- Abstract
Cooling water towers are commonly used in industrial and commercial applications. Industrial sites frequently have harsh environments, with certain characteristics such as poor air quality, close proximity to the ocean, large quantities of dust, or water supplies with a high mineral content. In such environments, the quality of electrical conductivity in the cooling water towers can be significantly negatively affected. Once minerals (e.g., calcium and magnesium) form in the water, conductivity becomes too high, and cooling water towers can become easily clogged in a short time; this leads to a situation in which the cooling water host cannot be cooled, causing it to crash. This is a serious situation because manufacturing processes are then completely shut down, and production yield is thus severely reduced. To solve these problems, in this study, we develop a practical designation for a photovoltaic industry company called Company-L. Three control methods are proposed: the motor control method, the PID control method, and the fuzzy PID control method. These approaches are proposed as solutions for successfully controlling the forced replenishment and drainage of cooling water towers and controlling the opening of proportional control valves for water release; this will further dilute the electrical conductivity and control it, bringing it to 300 µS/cm. In the experimental processes, we first used practical data from Company-L for our case study. Second, from the experimental results of the proposed model for the motor control method, we can see that if electrical conductivity is out of control and the conductivity value exceeds 1000 µS/cm, the communication software LINE v8.5.0 (accessible via smartphone) displays a notification that the water quality of the cooling water towers requires attention. Third, although the PID control method is shown to have errors within an acceptable range, the proportional (P) controller must be precisely controlled; this control method has not yet reached this precise control in the present study. Finally, the fuzzy PID control method was found to have the greatest effect, with the lowest level of errors and the most accurate control. In conclusion, the present study proposes solutions to reduce the risk of ice-water host machines crashing; the solutions use fuzzy logic and can be used to ensure the smooth operation of manufacturing processes in industries. Practically, this study contributes an applicable technical innovation: the use of the fuzzy PID control model to control cooling water towers in industrial applications. Concurrently, we present a three-tier monitoring checkpoint that contributes to the PID control method. [ABSTRACT FROM AUTHOR]

- Abstract
High-quality software tends to be expensive to develop and maintain because it is used in social infrastructures. In previous studies, a description format for requirement specifications was defined in a form that can be handled by machines, and customers were asked to describe their requirement specifications using this description format. However, a method for generating test cases from natural language documents has not been developed. We proposed a method to automatically generate test cases for system tests from requirement specifications. We applied this method to various system specifications and confirmed its usefulness. As a result, sufficient accuracy was obtained, confirming the usefulness of the proposed method. We also applied the proposed method to large-scale communication node software and clarified the specification-dependent characteristics of the proposed method. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Many new technologies are being used in dentistry, enhancing and accelerating dental procedures. However, there is still a lack of a comprehensive and coherent understanding of the extent of technology use and the factors influencing its adoption in any specific society. Objectives: This study aimed to investigate the frequency of digital technology use among dentists in Zahedan, Iran, in 2023. Methods: In this descriptive-analytical study, ninety-three dentists working in Zahedan city were investigated. Simple random sampling was used to select participants, and a questionnaire was administered that included sections on demographic information (gender, experience, workplace, level of degree, level of education), administrative and communicative aspects (4 questions), clinical and diagnostic aspects (9 questions), and reasons for not using certain technologies. The validity of the questionnaire was 100%, and the reliability was 0.8. Data analysis was performed using frequency analysis and comparisons between groups, which were conducted using the chi-square or Fisher's exact test. A P-value of less than 0.05 (P < 0.05) was considered statistically significant. Results: The usage rate of digital technologies among dentists in Zahedan was 60.2% low, 35.5% moderate, and 4.3% high. There was a significant relationship between the use of digital technologies and factors such as gender (P < 0.001), workplace (P < 0.001), experience (P < 0.006), and level of education (P < 0.002). However, no significant relationship was found between digital technology use and the level of degree. Digital radiography was the most commonly used technology, with a usage rate of 74.3%. The most frequently used administrative and communicative technology was the "use of communication program or software with other centers," at 49.9%. The majority of digital technologies began to be adopted from 2019 onwards. The main reason for not using administrative and communicative technologies was "inaccessibility," while the primary reason for not using clinical and diagnostic technologies was deemed "unnecessary use." Conclusions: The use of digital technologies by dentists in Zahedan was found to be low. Given the limited adoption of digital technologies in dentistry, it is essential to provide more training for dentists and to facilitate better access to these technologies in the field.

- Abstract
Mentorship refers to the guidance given by a mentor to a less experienced individual to enhance their professional and personal development. For graduate research students, seeking independent mentors external to their institution offers the rewarding opportunity to obtain objective guidance on a variety of work, study and life matters. This article outlines the steps taken to develop a professional society‐based, international mentoring program of over 70 participants. This 6‐month program aimed to connect graduate research students with more senior academic scientists in response to the limited networking opportunities imposed by the coronavirus disease 2019 (COVID‐19) pandemic in Australia. Outlined here are the resources used to maximize the potential of this successful program, which include (1) an 'Introduction to Mentoring' workshop, (2) the use of a mentoring software or communication strategy to maintain program momentum and (3) the integration of in‐person networking events. Overall, the program was a great success, with a high satisfaction rating (8.7/10) and a large number of participants reported that they would maintain their mentoring relationship. All participants stated that they would recommend the program to a peer, and thus reiterations of the program would likely be similarly well‐received and beneficial to the Australasian immunology community.

- Abstract
Progress in Information and Communication Technologies (ICT) can make a real difference in the quality-of-life of persons with Autism Spectrum Disorder (ASD) by acting on several aspects, from customized software for communication, to emotion recognition, to social behavior and also to provide systems for the observation of the wide spectrum of manifestations, to ease the diagnosis, to support the therapy, and to monitor the improvement and the growth of children with ASD. This has been achieved by the introduction of a large number of innovative technologies, spanning from Internet of Things, to robotics, virtual and augmented reality, etc. Differently from other surveys on the same research area, we focus this survey on innovative technologies used in this field, and we organize a classification of the papers based on three different but strictly crossed axis, namely the triad of impairment (either communication, social interaction, or social behaviors), research purpose (either diagnosis or therapy), and system activity (either monitoring or intervention).

- Abstract
The rapid changes and advanced technology do not ensure the performance of the communication system. The system is still not resistant to signal strength, and multipath fading, etc. Due to fixed spectrum policy the system became less reliable and inefficient in spectrum utilization. To enhance the system performance, we use this software-based approach in WCS. The system and equipment design were proprietary, there were very limited openness both in hardware and software. Software Defined Radio(SDR) offers low operational cost, holistic management, and also customised infrastructure. Therefore, besides theoretical analysis, the approach should be also, to do the practical implementation of the fairly widespread technology using the platforms. Reconfigurability of the SDR provides dynamic operation, hence in numerous applications viz military, defense, and for relaying, etc. Proposed system deploys SDR that changes its parameters according to the interaction with the environment. The paper demonstrate the implementation of software based communication system using USRP, HackRF One and VUSDR. The paper emphasis software-based communication, using VUSDR, HackRF, and USRP N210 for reliable communication. [ABSTRACT FROM AUTHOR]

- Abstract
Rationale: The sampling throughput of immediate drop‐on‐demand technology (I.DOT) coupled with an open port sampling interface (OPSI) is limited by software communication. To enable much‐needed high‐throughput mass spectrometry (MS) analysis capabilities, a novel software was developed that allows for flexible sample selection from a 96‐well plate and for maximized analysis throughput using I.DOT/OPSI‐MS coupling. Methods: Wells of a 96‐well I.DOT plate were filled with propranolol solution and were used to test maximum sampling throughput strategies to minimize analysis time. Demonstration of chemical reaction monitoring was done using acid‐catalyzed ring closure of 2,3‐diaminonaphthalene (DAN) with nitrite to form 2,3‐naphthotriazole (NAT). Analytes were detected in positive electrospray ionization mode using selected reaction monitoring. Results: A maximum throughput of 1.54 s/sample (7.41 min/96‐well plate with three technical replicates) was achieved, and it was limited by the peak width of the MS signal resulting in an occasional slight overlap between the peaks. Relative standard deviation was 10 ± 1% with all tested sampling strategies. Chemical reaction monitoring of DAN to NAT using nitrite was successfully accomplished with 2 s/sample throughout showing almost complete transformation in 10 min with no signal overlap. Conclusions: This work illustrates the development of a noncontact, automated I.DOT/OPSI‐MS system with improved throughput achieved through an optimized software interface. Its achievable analysis time and precision make it a viable approach for drug discovery and in situ reaction monitoring studies. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: This paper aims to automatically obtain the implant parameter from the CBCT images to improve the outcome of implant planning. Design/methodology/approach: This paper proposes automatic simulated dental implant positioning on CBCT images, which can significantly improve the efficiency of implant planning. The authors introduce the fusion point calculation method for the missing tooth's long axis and root axis based on the dental arch line used to obtain the optimal fusion position. In addition, the authors proposed a semi-interactive visualization method of implant parameters that be automatically simulated by the authors' method. If the plan does not meet the doctor's requirements, the final implant plan can be fine-tuned to achieve the optimal effect. Findings: A series of experimental results show that the method proposed in this paper greatly improves the feasibility and accuracy of the implant planning scheme, and the visualization method of planting parameters improves the planning efficiency and the friendliness of system use. Originality/value: The proposed method can be applied to dental implant planning software to improve the communication efficiency between doctors, patients and technicians. [ABSTRACT FROM AUTHOR]

- Abstract
Fighter jets are a critical national asset. Because of the high cost of their manufacture and that of their related equipment, both pilots and maintenance personnel must complete intensive training before coming into contact with a jet. Due to gradual military downsizing, one-on-one training is often impracticable, and the level of familiarization with procedures among personnel is difficult to measure. The US military introduced a chatbot as part of its digital training material to enhance training effectiveness and avoid equipment damage. In this study, the contribution of an artificial intelligence (AI) chatbot in training is explored. To evaluate the necessity of an AI chatbot, research samples were divided into two groups, namely an experimental and a control group, with 20 people in each group. A paired t test was employed for differentiation analysis of pretest and posttest average scores, revealing that the two groups exhibited a statistically significant improvement in their learning performance. In addition, the blend of analysis of variance results indicated significant differences between the two groups. The chatbot training was more effective than traditional instructor teaching in terms of trainee performance improvement. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: Efficient appointment scheduling in the outpatient setting is challenged by two main factors: variability and uncertainty leading to undesirable wait times for patients or physician overtime, and events such as no‐shows, cancellations, or walk‐ins can result in physician idle time and under‐utilization of resources. Some methods have been developed to optimize scheduling and minimize wait and idle times in the inpatient setting but are limited in the outpatient setting. Methods: People and Organization Development, an internal group of organizational developers, led the development of a solution that selects the optimal group of appointments for a patient that minimizes the time between associated procedures as well as lead time built using a linear integer program. This program takes appointment requests, availability of resources, order constraints, and time preferences as inputs, and provides a list of the most optimal groupings as an output. Included in the methodology is the technical infrastructure necessary to deploy this within an electronic medical record system. Implementation and Test Plan: A pilot has been designed to run this algorithm in a single department. The pilot will include training staff on the new workflow, and conducting informal interviews to gather qualitative data on performance. Key performance indicators such as schedule utilization, resource idle time, patient satisfaction, average appointment lead time, and average waiting time will be closely monitored. Discussion: The model is limited in accounting for variability in appointment length potentially resulting in inaccurate schedules for healthcare providers and patients. Future states would incorporate certain visit types starting through machine learning techniques. Additionally expanding our data pipeline and processing, developing greater communication software, and expanding our research to include other departments and subspecialties, will enhance the accuracy and flexibility of the algorithm and enable healthcare providers to provide better care to their patients.

This study examines the opinions of teachers about the digital competencies of administrators in schools. The study was carried out with the phenomenological design, which is one of the qualitative research methods. In the study, the participants were determined by using the criterion sampling method, which is one of the non-probability sampling methods. The participants of the study consisted of 41 teachers who completed a non-thesis master's degree in the field of Educational Administration at the Fırat University Institute of Educational Sciences in 2022-2023. In the study, semi-structured interview forms containing questions prepared by the researchers were prepared as a data collection tool, and semi-structured interview forms were applied by making face-to-face interviews. The obtained data were analyzed by content analysis method. In line with the findings obtained in the study, teachers stated that school administrators should have digital competencies such as using digital devices, basic office software, officially used package programs, social media and online communication software. They stated that managers with digital competencies will increase efficiency in the organization, use time and energy more effectively, increase the effectiveness of internal communication and solve problems faster. It has been stated that the pandemic process has made a significant contribution to the use and development of digital competencies, and that managers have developed digital competencies in order to quickly adapt to the process.

Developing the communication skills of software engineering graduates to meet industry requirements is a challenge for educators. This study presents a project-based learning framework that promotes students' communication skills in a software engineering project course. The questionnaire on selfefficacy for software development (CSESD) was designed for students' self-assessment of their confidence in communication skills. Findings indicate that students' CSESD increased significantly after the course ended. Educators can apply the designed framework to software development-related project courses. The CSESD questionnaire can be used to assess students' confidence in their communication skills and assist educators in preparing students' readiness before graduation. [ABSTRACT FROM AUTHOR]

- Abstract
Recent advances in automation have fostered the development of unattended data collection services at a handful of synchrotron facilities worldwide. At the Swiss Light Source, the installation of new high-throughput sample changers at all three macromolecular crystallography beamlines and the commissioning of the Fast Fragment and Compound Screening pipeline created a unique opportunity to automate data acquisition. Here, the DA+ microservice software stack upgrades, implementation of an automatic loop-centering service and deployment of the Smart Digital User (SDU) software for unattended data collection are reported. The SDU software is the decision-making software responsible for communications between services, sample and device safety, sample centering, sample alignment with grid based X-ray diffraction and, finally, data collection.

- Abstract
A task to identify occupied seats in government buses for passengers emerges in the digital communicating world. In this project, the second stage is verifying a system with tagged seat sense and a camera for detecting whether the seat is occupied. It sees the availability or occupancy status of seats in any coach. In this work, detection of face overcomes the drawback caused due to seat sensor that indicates the seat is occupied when any objects are placed. The camera is inserted in the buses, connected with Raspberry Pi 3 B+ microcontroller. When the vehicle starts from its corresponding station, the images of people traveling are captured, adjusted, and improved by software communication. The transferred images are processed to count the commuters in the vehicle to find the vacancy of seats so that the passengers waiting in various stops can monitor the seat is available or not.

- Abstract
Reports have shown that the demand for data managed by wireless systems is expected to grow by more than 500 exabytes by 2025 and beyond. 5G networks are predicted to meet these demands, provided that the spectrum resources are well managed. In this paper, an enhanced dynamic spectrum allocation (E-DSA) method is proposed, which incorporates a cooperative type of game theory called the Nash bargaining solution (NBS). It was assumed that there is one primary user (PU) and two secondary users (SU) in the network and their spectrum allocation was analyzed by testing the validity of the algorithm itself by using price weight factors to control the costs of the spectrum sharing. The solution was established by combining a proposed multiplexing method called the Filter Bank Multicarrier (FBMC) for 5G configuration, with the E-DSA algorithm to maximize the throughput of a heterogeneous 5G network. It was shown that the throughputs for 5G with EDSA implementation were always higher than those of the ones without E-DSA. The simulation was done using the LabVIEW communication software and was analyzed based on a 5G urban macro and micro network configuration to validate the heterogeneity of the network.

In a recent article and in the context of open science, the FAIR for Research Software (FAIR4RS) working group introduced the FAIR (Findable, Accessible, Interoperable, and Reusable) principles for research software. This ThinkEPI discusses the difference in these principles between research software (created during research) and software in research (used to write, develop, or process scientific work). Some questions are proposed for discussion, such as: Is it open science if it was written, developed, or processed with proprietary software? Should we consider software in research -and not just research software- as another piece of open science? The debate is currently even more relevant due to the recent publication of the first National Open Science Strategy (ENCA) 2023-2027 by the Government of Spain, and its content that includes, among other topics, references to open source and free software.

- Abstract
Drawing insight from Toyin Falola's call for African scholars to Africanize knowledge, this article argues for reviewing the digital technological tools used for African Studies research to process and present African data properly. To achieve this, the inadequacies of digital humanities (DH) for specific areas of African Studies will be highlighted, especially in the deployment of digital humanities tools. The major challenge is the distortion and constraint experienced in processing and presenting research through DH means of translation and communication. The article argues that such technological limitation has its root in the incompatibility of the epistemological frameworks within which those digital tools were developed. The article discusses Ojú lòrówà ('discussion is in the eye'), that is, 'communication takes place when we see physically' – a theory of communication in African society used as a model to highlight the importance of African context to African scholars in their exploration of African history, technology, culture, philosophy and tradition. The indigenous theory is an appropriate model for developing digital and virtual software for African scholars in human communication. The article concludes by urging scholars in African Studies to ensure that the digital tools employed in African Studies can collect data and process and present data adequately without losing the original meaning or sense.

Purpose: In this study, the effect of cognitive‐behavioral therapy (CBT) on death anxiety and depression was investigated in patients with heart failure. Design and Methods: In this quasi‐experimental study, 66 patients with heart failure were randomly assigned to intervention (n = 33) and control (n = 33) groups. Data collection was done using a demographic questionnaire, Templer death anxiety scale, and Beck depression inventory. Findings: It was found that the overall scores of death anxiety and depression in posttest were significantly lower than those at the follow‐up stage in the intervention group. Practice Implications: CBT could significantly reduce death anxiety and depression in patients with heart failure. Therefore, it is recommended to equip nurses with CBT trainings to manage patients with heart failure better. [ABSTRACT FROM AUTHOR]

- Abstract
Information is one of the most valuable objects of modern life. Accessing it has become incredibly easy with the development of global computer networks. At the same time, the ease and speed of such access significantly increased the threat of data security violations in the absence of means to protect them. The relevance of the topic lies in the fact that in today's realities messengers are an integral part of the life of almost every person in the world, therefore the security of personal information has a high priority. The purpose of the work is to develop a method of hiding messages in a set of sequential images, its software implementation and use in the messenger. To achieve the defined goal, the following tasks were formed: analysis of existing popular messengers and their methods of information protection, analysis of the relevance of steganography in messengers; development of a steganographic method of hiding messages in a set of consecutive images; development of software implementation of the proposed method; study of the resistance of the proposed hiding method to possible disturbed actions by the attacker; software implementation of the messenger that uses the proposed method. The object of the study is the process of ensuring the security of the user's personal information when using messengers. The subject of the research is methods of hiding information and algorithms for transporting messages in messengers. The novelty of the work lies in the development of a method for encoding messages using images, which was first used in a user messenger. The developed method of hiding messages is implemented in an independent software product for communication, in addition, its implementation can be used in other existing messengers.

- Abstract
Agricultural fertilization and irrigation are closely related to the problems of agricultural yield, product quality, and environmental pollution. Precision fertilization and irrigation is an effective method to solve this problem. In order to precisely control plant fertilization and irrigation, a monitoring system is designed and implemented using open-source software, loose communication structure, industrial control computer (IPC), programmable logic controller (PLC), and control and monitoring devices. The control command management subsystem of the system's upper computer is built using GoWin IPC, cloud server, mobile devices, and 4G wireless network. Each application running in the upper computer is developed using open-source software such as PostgreSQL, Smobiler, etc. The fertilization and irrigation monitoring subsystem of the lower computer was built using HollySys PLC model LE5107L and different sensors for various data parameters as control units. The system allows real-time remote monitoring and control of agricultural precision fertilization and irrigation through mobile applications, with an average communication delay of 1.45 s between the upper and lower units, and less than 3 s overall, allowing for long-term stable communication. The current system can adapt to the variable environment in the field and has been operating stably in the field for 2 months. This paper provides a convenient system construction solution for field farmland where network wiring is not possible, and it has low construction and maintenance costs, reliable operation, and a flexible structure for agricultural applications.

The article discusses the basic principles of the implementation of the prototype of the communication, navigation and power supply subsystems in the onboard equipment of unmanned aerial vehicles. Ensuring the correct interaction of peripheral devices of unmanned aerial vehicles is an important design stage. In this case, the used element base must ensure communication between the software modules of the onboard software and peripheral devices within the framework of the architectural solution of the project. At the design stage, the proposed method of replacing real subsystems with their prototypes for debugging the software environment of the life cycle of the cross-platform onboard software of an unmanned aerial vehicle has demonstrated high efficiency. To emulate the basic modules, a software environment developed by the authors was used to ensure the life cycle of cross-platform onboard software and onboard equipment modules for an unmanned aerial vehicle.

- Abstract
The Internet of Things (IoT) is an interconnected network of computing nodes that can send and receive data without human participation. Software and communication technology have advanced tremendously in the last couple of decades, resulting in a considerable increase in IoT devices. IoT gadgets have practically infiltrated every aspect of human well-being, ushering in a new era of intelligent devices. However, the rapid expansion has raised security concerns. Another challenge with the basic approach of processing IoT data on the cloud is scalability. A cloud-centric strategy results from network congestion, data bottlenecks, and longer response times to security threats. Fog computing addresses these difficulties by bringing computation to the network edge. The current research provides a comprehensive review of the IoT evolution, Fog computation, and artificial-intelligence-inspired machine learning (ML) strategies. It examines ML techniques for identifying anomalies and attacks, showcases IoT data growth solutions, and delves into Fog computing security concerns. Additionally, it covers future research objectives in the crucial field of IoT security. [ABSTRACT FROM AUTHOR]

- Abstract
Recently, too much afford has been conducted toward development of novel communication techniques (biological inspired) for implementing in nano and micro scale systems inspired from electro-chemical communication systems that naturally used by living beings. One of these techniques is known as nano/micro scale communication (NMSC) in which chemical signals are used as carriers for transmission of information through fluid media. The information carrier particles used in such communication systems consist of biological components such as DNA and protein components. Studies regarding NMSC are considered to highly contribute to the developments in the field of nano-technology which can be used to detect and treatment of the some unsolved illness yet. Therefore, in this study, software based a new NMSC model that could potentially be used in nano-scale systems were developed and analysed in terms of communication performance. Firstly, Diffusion constant which affect the communication performance of the software based NMSC model is derived using some Physics laws such as Fick's. Secondly, different forms of receivers such as sphere, cube and rectangular prism topologies have been tried for increasing the rate of molecule reception and reducing the inter symbol interference of the receiver. It was observed that the signal transmission rate increased and the interference decreased with the use of a cube receiver model. The results obtained from the proposed NMSC model encourages one to think that such receiver models might have the potential for Alzheimer and many illness which cause missing and/or wrong communication of the cells.

- Abstract
Distributed-memory graph algorithms are fundamental enablers in scientific computing and analytics workflows. A majority of graph algorithms rely on the graph neighborhood communication pattern, i.e., repeated asynchronous communication between a vertex and its neighbors in the graph. The pattern is adversarial for communication software and hardware due to high message injection rates and input-dependent, many-to-one traffic with variable destinations and volumes. We present benchmarks and performance analysis of graph neighborhood communication on modern large-scale network interconnects from four supercomputers: ALCF Theta, NERSC Cori, OLCF Summit and R-CCS Fugaku. Our benchmarks characterize communication from the perspectives of latency and throughput. Benchmark parameters make it possible to mimic the behaviors of complex applications on real world or synthetic graphs by varying work distribution, remote edges, message volume, and per-vertex work. We find that minor changes in the input graph can substantially increase latencies; and contention can develop in memory caches and network stacks before contention in the network itself. Further, latencies and contention vary significantly for different graph neighborhoods, motivating the need for exploring asynchronous algorithms in greater detail. When adding work, load imbalance on real-world graphs can be pronounced: latencies for the 99th percentile were 8–128× than the corresponding average latencies. Our results help analysts and developers understand the performance implications of this important pattern, especially for the impending exascale platforms. [ABSTRACT FROM AUTHOR]

- Abstract
This work presents results related to the development and validation of a remotely controlled experiment and a three-dimensional simulator, aimed at the practical study of the inverse square law of distance. The prototype creation steps consisted in the manufacture of the physical mechanisms, hardware and software necessary for the communication and control between the user and the experiment through a device with internet access, making it possible to measure the luminous intensity of a light source that gradually moves away of a photoresistor (LDR, "Light Dependent Resistor"). The simulator development stages were divided into 3D graphic modeling of all components and interaction programming, animation and data simulation, thus creating the application for Android devices. The prototype validation was performed using statistical analysis and error propagation, in addition to comparing the data obtained with a lux meter. The results were satisfactory for the validation of the prototype and the quality of the experimental practice tools, due to the relative low cost spent and its potential for use.

- Abstract
Requirements specifications are essential to properly communicate requirements among the software development team members. However, each role in the team has different informational needs in order to perform their activities. Thus, the requirements engineer should provide the necessary information to meet each team member's necessities to reduce errors in software development due to inadequate or insufficient communication. Although some research is concerned with communicating requirements among clients and analysts, no related research has been found to evaluate and improve requirements communication within the software development team. With this in mind, we present the ReComP framework, which assists in the identification of problems in the artifacts used to communicate requirements, identification of informational requirements for each role of the development team, and provide improvement suggestions to address requirements communication problems. ReComP was developed using the Design Science Research (DSR) method and this paper presents the results of two DSR cycles considering the use of ReComP for the developer and tester roles by using, respectively, user stories and use cases as requirements specifications. The results provide evidence that ReComP helps software development teams to identify and improve issues in the requirements specifications used for project communication. In two independent studies, ReComP was able to decrease the frequency of problems by 77% in user stories identified by developers and the frequency of all (100%) problems in use cases identified by testers.

- Abstract
Dynamic traffic of multicast communication in the Software Defined Network environment focused less though it is more natural and practical. In multicast communication, the traffic is dynamic due to the dynamic group memberships (i.e., participants join and leave the group anytime), which are not explored much in the previous research works. The multicast in dynamic traffic requires a method to handle dynamic group membership and minimum tree alteration for every join and leave of participants from the multicast group. This paper proposes a multicast tree construction algorithm, which considers receiving devices and network capability as base parameters to construct the multicast path. The proposed routing method uses Dijkstra's Shortest Path algorithm for initial tree formation, identifies a multicast path, and processes the Shortest Path Tree to reduce the overall hop count and path cost. The multicast tree generated by the proposed enables the dynamic join and leaves of participating devices with reduced tree alteration using more common paths to reach the devices. The implementation and results show that the proposed method works efficiently in resource utilization with a reduced hop count and quality for multicast communication in static and dynamic scenarios. Also, the results demonstrate that the proposed method generates a stable common path for multicast communication. [ABSTRACT FROM AUTHOR]

- Abstract
Background: The objective of this study was to investigate inter- and intraobserver reliability of the morphological Mutch classification for greater tuberosity (GT) fragments in consecutive proximal humerus fractures (PHF) regardless of the number of parts according to the Codman classification system for three different imaging modalities (plain radiographs, two-dimensional [2-D] computed tomography [CT], and reformatted, three-dimensional [3-D] CT reconstruction). Materials and methods: One hundred thirty-eight consecutive PHF with GT involvement were identified between January 2018 and December 2018 in a supraregional Level 1 trauma center. GT morphology was classified by three blinded observers according to the morphological Mutch classification using the picture archiving and communication software Visage 7.1 (Visage Imaging Inc., San Diego, CA, USA). Fleiss' and Cohens' kappa were assessed for inter- and intraobserver reliability. Strength of agreement for kappa (k) values was interpreted according to the Landis and Koch benchmark scale. Results: In cases of isolated GT fractures (n = 24), the morphological Mutch classification achieved consistently substantial values for interobserver reliability (radiograph: k = 0.63; 2-D CT: k = 0.75; 3-D CT: k = 0.77). Moreover, use of advanced imaging (2-D and 3-D CT) tends to increase reliability. Consistently substantial mean values were found for intraobserver agreement (radiograph: Ø k = 0.72; 2-D CT: Ø k = 0.8; 3-D CT: Ø k = 0.76). In cases of multi-part PHF with GT involvement (n = 114), interobserver agreement was only slight to fair regardless of imaging modality (radiograph: k = 0.3; 2-D CT: k = 0.17; 3-D CT: k = 0.05). Intraobserver agreement achieved fair to moderate mean values (radiograph: Ø k = 0.56; 2-D CT: Ø k = 0.61; 3-D CT: Ø k = 0.33). Conclusion: The morphological Mutch classification remains a reliable classification for isolated GT fractures, even with 2-D or 3-D CT imaging. Usage of these advanced imaging modalities tends to increase interobserver reliability. However, its reliability for multi-part fractures with GT involvement is limited. A simple and reliable classification is missing for this fracture entity. [ABSTRACT FROM AUTHOR]

- Abstract
Recently, a concept of virtual emotion barrier by wireless signal gained a lot of interests because it supports human emotion recognition within given IoT environment. If detection of human emotion can be made with possibly high detection accuracy by virtual emotion barrier, it can be utilized to an extensive scope of emotion-based applications and communication software services. But, some IoT devices failures in the barrier may cause emotion-based system performance degradation critically. Also, thanks to recent advent of technology, intelligent smart UAVs with rapid speed are considered as promising devices when existing infrastructures are recovered. In this study, fault-tolerant mutual assisted virtual emotion barrier system is introduced with intelligent autonomous UAVs in convergent smart cities. Moreover, we present a formal definition of the problem whose goal is maximizing entire total accuracy of emotion detection where the failed locations are recovered by UAVs’ movement from initial locations without any potential conflicts among UAVs. A greedy UAV movement scheme that constructs resilient virtual emotion barriers is proposed by handling those failed parts in the barriers continuously. Moreover, the proposed schemes are executed by comprehensive simulations with useful scenarios and we evaluate the earned outcome. [ABSTRACT FROM AUTHOR]

- Abstract
Empirical software engineering research relies on good communication with industrial partners. Conducting joint research both requires and contributes to bridging the communication gap between industry and academia (IA) in software engineering. This study aims to explore communication between the two parties in such a setting. To better understand what facilitates good IA communication and what project outcomes such communication promotes, we performed a case study, in the context of a long‐term IA joint project, followed by a validating survey among practitioners and researchers with experience of working in similar settings. We identified five facilitators of IA communication and nine project outcomes related to this communication. The facilitators concern the relevance of the research, practitioners' attitude and involvement in research, frequency of communication and longevity of the collaboration. The project outcomes promoted by this communication include, for researchers, changes in teaching and new scientific venues, and for practitioners, increased awareness, changes to practice, and new tools and source code. Besides, both parties gain new knowledge and develop social‐networks through IA communication. Our study presents empirically based insights that can provide advise on how to improve communication in IA research projects and thus the co‐creation of software engineering knowledge that is anchored in both practice and research.

- Abstract
The importance of online handwriting recognition technology has steadily increased in recent years. This importance stems from the rapid increase in the number of handheld devices with digital pens and styluses. In addition, a large number of currently available communication software have been designed to support handwriting boards. During the past decade, most innovation in online handwriting recognition technology was geared towards supporting languages using the Latin alphabet. There has been a lack of sufficient development of Arabic online handwriting recognition (AOHR) systems, especially ones that perform recognition at the sentence level. In this paper, we present DeepOnKHATT, an end-to-end AOHR based on bidirectional long short-term memory and the connectionist temporal classification (BLSTM-CTC). DeepOnKHATT is capable of performing recognition at the sentence level in real-time. We evaluated our system utilizing two open access databases: CHAW and Online-KHATT. Our model achieved a 4.08% character error rate (CER) and a 14.65% word error rate (WER) against the CHAW dataset and a 12.24% CER and a 28.35% WER against the Online-KHATT dataset. A Comparison of the functionality of our proposed model to that of other existing systems showed that DeepOnKHATT had outperformed these systems. [ABSTRACT FROM AUTHOR]

- Abstract
A new Muon-to-Central-Trigger Processor Interface (MUCTPI) was built as part of the upgrade of the ATLAS Level-1 trigger system for the next Run of the Large Hadron Collider at CERN. The MUCTPI has 208 high-speed optical serial links for receiving muon candidates from the muon trigger detectors. Three high-end field-programmable gate arrays (FPGAs) are used for real-time processing of the muon candidates, for sending trigger information to other parts of the trigger system, and for sending summary information to the data acquisition and monitoring system. A System-on-Chip (SoC) is used for the control, configuration, and monitoring of the hardware and the operation of the MUCTPI. The SoC consists of an FPGA part and a processor system (PS). The FPGA part provides communication with the processing FPGAs, while the PS runs software for communication with the run-control system of the ATLAS experiment. In this article, we will describe our experience with running CentOS Linux on the SoC. Cross-compilation together with the existing framework for building the ATLAS trigger and data acquisition (TDAQ) software is being used in order to allow the deployment of the TDAQ software directly on the SoC.

- Abstract
Brain–computer interfaces (BCIs) development is closely related to physics. In this paper, we review the physical principles of BCIs, and underlying novel approaches for registration, analysis, and control of brain activity. We analyze recent advances in BCI studies focusing on their applications for (i) controlling the movement of robots and exoskeletons, (ii) revealing and preventing brain pathologies, (iii) assessing and controlling psychophysiological states, and (iv) monitoring and controlling normal and pathological cognitive activity. We consider the BCI as a hardware/software communication system that allows interaction of humans or animals with their surroundings without the involvement of peripheral nerves and muscles, using control signals generated from brain cerebral activity. Classifying BCIs into three main types (active, reactive and passive), we describe their functional models and neuroimaging methods, as well as novel techniques for signal enhancement and artifact recognition and avoidance, to improve BCI performance in real time. We also review different BCI applications, including communications, external device control, movement control, neuroprostheses, and assessment of human psychophysiological states. Then, we describe the most common techniques for the analysis and classification of electroencephalographic (EEG) and magnetoencephalographic (MEG) data. Special attention is paid to modern technology based on machine learning and reservoir computing. We discuss main results on the creation and application of BCIs based on invasive and noninvasive EEG recordings. First, we consider neurointerfaces for controlling the movement of robots and exoskeletons. Second, we describe BCIs for diagnosis and control of pathological brain activity, in particular, epilepsy. We also discuss the results on the development of invasive BCIs for predicting and mitigating absence epileptic seizures. After that, we focus on passive neurointerfaces for assessing and controlling a person's psychophysiological states and cognitive activity. Special attention is given to optogenetic brain interfaces using photostimulation to deliver intervention to specific cell types. We outline the basic principles of optogenetic neurocontrol and extracellular electrophysiology recording. We also describe the state-of-the-art of miniaturized closed-loop optogenetic devices to control normal and pathological brain activities. Further, we discuss the new emerging technological trend in the BCI development which consists in using neurointerfaces to improve the interaction between people, so-called brain-to-brain interfaces (BBIs). Such interfaces can increase the efficiency of collaborative processes when working in a group. We propose a BBI which distributes a cognitive load among all team members working on a common task. This BBI allows sharing the workload among the participants according to their current cognitive performance, estimated from their electrical brain activity. The novel results of the brain-to-brain interaction are promising for the development of a new generation of communication systems based on the neurophysiological brain activity of interacting persons, where the BBI estimates physical conditions of each partner and adapts the assigned task accordingly. Finally, we trace the main historical epochs in BCI development and applications and highlight possible future directions for this research area, including hybrid BCIs. [ABSTRACT FROM AUTHOR]

- Abstract
The communication network of wide‐area protection may be interrupted because of the severe environment or artificial damage. The delay of communication will increase so much that the wide‐area protection cannot work normally in some severe cases mentioned above. That is one of the factors which affect the application of wide‐area protection. A reconstruction algorithm including different circuitous modes for different situations is proposed to maintain the transmission of the data on the interrupted channel. On the one hand, a single‐path circuitous mode is proposed when the data in the shut path is small. In this situation, the best circuitous path can be found out by Floyd considering the several reference factors affection. On the other hand, a multi‐paths circuitous model is proposed to solve the congestion which is caused by detouring under single‐path circuitous mode. The available margin of the bandwidth of the weakest channel called the short‐board channel in each circuitous path is the focus of the algorithm. In this situation, the optimal shunt coefficients are determined according to the bandwidth margin ratio of the short‐board channel. Then the data on the interrupted channel is divided into several streams based on the shunt coefficients. Therefore, the balance of the communication network can be ensured after the interrupted channel is divided. Finally, with OPNET communication simulation software, the IEEE14 nodes network is built. Delay and balance of system based on this reconstruction algorithm are tested. © 2021 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC. [ABSTRACT FROM AUTHOR]

- Abstract
The rapid development of technology and the Internet, drastically change the environment for both, consumers and businesses. The Internet is widely accepted by consumers and its use obviously changes their behavior. In order to be efficient and sustainable in their operations, businesses need to respond quickly to these change. Customer relationships management is a business strategy used to identify consumer needs and their behavior and to build long-term and sustainable customer relationships. Although customer relationships management is a business activity practiced from a lot of generations, today, building long-term customer relationships is at the core of business sustainability and becomes unacceptable without the use of digital communication technologies and software applications. The aim of this paper is to research and analyze the CRM systems in order to give an overview of the benefits of certain applications that build successful customer relationships.

- Abstract
Synchronizing movements with an external periodic stimulus, such as tapping your foot along with a metronome, is a remarkable human skill called sensorimotor synchronization. A growing body of literature investigates this process, but experiments require collecting responses with high temporal reliability, which often requires specialized hardware. The current article presents and validates TeensyTap, an inexpensive, highly functional framework with excellent timing performance. The framework uses widely available, low-cost hardware and consists of custom-written open-source software and communication protocols. TeensyTap allows running complete experiments through a graphical user interface and can simultaneously present a pacing signal (metronome), measure movements using a force-sensitive resistor, and deliver auditory feedback, with optional experimenter- specified artificial feedback delays. Movement data is communicated to a computer and saved for offline analysis in a format that allows it to be easily imported into spreadsheet programs. The present work also reports a validation experiment showing that timing performance of TeensyTap is highly accurate, ranking it among the gold standard tools available in the field. Metronome pacing signals are presented with millisecond accuracy, feedback sounds are delivered on average 2 ms following the subjects' taps, and the timing log files produced by the device are unbiased and accurate to within a few milliseconds. The framework allows for a range of experimental questions to be addressed and, since it is open source and transparent, researchers with some technical expertise can easily adapt and extend it to accommodate a host of possible future experiments that have yet to be imagined.

- Abstract
Worker health centers and health zones provide occupational healthcare services to workers in underserved areas of industrial health. Health zones cannot counsel workers on occupational disease prevention; worker health center personnel have to provide such services through in-person visits. Video teleconsultation can increase the accessibility of high-quality services to workers who visit health zones and improve professional personnel's efficiency. This study aimed to develop a system and an infrastructure that could facilitate video teleconsultation services between worker health centers and health zones, and analyze the services' operation status. A video teleconsultation process based on the role of local and remote institutions was designed. Based on the designed services, a web system supporting teleconsultation and an integrated gateway guaranteeing the interface with medical equipment in the web environment was developed. After analyzing the working environment, an infrastructure consisting of networks, video equipment, medical equipment, and servers necessary for teleconsultation was designed. Statistical results from the developed system and a satisfaction survey conducted by the Korea Occupational Safety and Health Agency were used to analyze the video teleconsultation services' operation status. A system, gateway, and hardware infrastructure within 21 worker health centers and 21 health zones has been operating this service since January 1, 2018. Over two years, the total number of teleconsultation service users was 4979, and the total number of questionnaire respondents was 1270. The total number of service activities was 6388 and total satisfaction was rated as 4.58 (± 0.59) out of 5. In this study, video teleconsultation services were evaluated as being very satisfactory. In particular, service accessibility and local medical personnel service were rated highly, demonstrating that the developed system and infrastructure were well designed according to the goals of the project.

- Abstract
System families (Software Product Lines) are becoming omnipresent in application areas ranging from embedded system domains to system-level software and communication protocols. Software Product Line methods and architectures allow effective building many custom variants of a software system in these domains. In many of the applications, their rigorous verification and quality assurance are of paramount importance. Lifted model checking for system families is capable of verifying all their variants simultaneously in a single run by exploiting the similarities between the variants. The computational cost of lifted model checking still greatly depends on the number of variants (the size of configuration space), which is often huge. Variability abstractions have successfully addressed this configuration space explosion problem, giving rise to smaller abstract variability models with fewer abstract configurations. Abstract variability models are given as modal transition systems, which contain may (over-approximating) and must (under-approximating) transitions. Thus, they preserve both universal and existential CTL properties. In this work, we bring two main contributions. First, we define a novel game-based approach for variability-specific abstraction and refinement for lifted model checking of the full CTL, interpreted over 3-valued semantics. We propose a direct algorithm for solving a 3-valued (abstract) lifted model checking game. In case the result of model checking an abstract variability model is indefinite, we suggest a new notion of refinement, which eliminates indefinite results. This provides an iterative incremental variability-specific abstraction and refinement framework, where refinement is applied only where indefinite results exist and definite results from previous iterations are reused. Second, we propose a new generalized definition of abstract variability models, given as so-called generalized modal transition systems, by introducing the notion of (must) hyper-transitions. This results in more precise abstract models in which more CTL formulae can be proved or disproved. We integrate the newly defined generalized abstract variability models in the existing abstraction-refinement framework for game-based lifted model checking of CTL. Finally, we evaluate the practicality of this approach on several system families. [ABSTRACT FROM AUTHOR]

This paper aims to assist future organizers of international online conferences with designing and realizing these events. On the basis of the authors' experience of having to move a corpus linguistics conference – originally planned as a physical event – into the digital space, this paper describes the conference's organization and management structure, outlines the software and communication tools used and sketches what is important to foster interaction and discourse among participants. The paper contains a manual and a checklist for preparing an online conference, and a discussion of the chances of online and hybrid conferences in terms of outreach, Open Access and co-creation. It ends with an appeal to colleagues to devise conferences with courage, develop new ways of transferring linguistic research findings (to the public) and to move out of their comfort zones to sustainably use the digital transformation for innovative paths of exchanging research findings.

- Abstract
Many industries often use different devices and controllers in automation systems. They all face the same difficulty how to exchange data between all those components. This paper proposed the implementation of OPC Server as software interface on communication between two different controllers, PLC Mitsubishi and PLC Omron. The main advantage of the method is the compatibility and solution for the factory difficulty problem because of using several driver controller. The compatibility among the different platforms of both controller, PLC Mitsubishi and PLC Omron, can be reached by use of KEPServerEx6 (OPC server) as a software interface. To test the compatibility amongst two different controllers, there was developed and implemented two field application devices, bottle unscramble and bottle filling station. This implementation shows OPC Server technology resolving data compatibility issues between different platforms and reducing development costs. It is envisaged that the method can be very useful to realize integration. [ABSTRACT FROM AUTHOR]

- Abstract
A virtual environment (VE) of an industrial splitter has been developed to test a dynamic real-time optimizer prior to on-site deployment. The paper describes the architecture of the VE, which represents the process using the EcosimPro© modeling and simulation software, and a real-time manager to maintain a controlled pace of simulation progress. The virtual process has been integrated with the same commercial predictive controller (Aspen© DMC) as installed in the plant (even with the same configuration) and a dynamic real-time optimizer has been developed in Matlab© and implemented on top of it, allowing the VE to test the optimization layer before deployment in the real factory. The data generated by the plant is stored using InfluxDB©, a time series data platform, for further analysis. The results show that the VE allows revamp studies to be conducted with less cost and more confidence. • A virtual environment (VE) of an industrial process has been developed. • The VE uses the same industrial communication and software as the plant. • The VE allows reliable validation of industrial control software. • The VE increases the confidence of industrial staff in revamping studies.

- Abstract
Universal Music Group has signed a new licensing deal with Meta Platforms, allowing its music to be used on WhatsApp. This expands on their previous agreement in 2017, which covered music used in the background of videos on Facebook, Instagram, Messenger, and Oculus. The new deal includes short-form video and licensed music for WhatsApp, providing monetization opportunities for Universal Music artists and songwriters. The agreement also addresses the issue of unlicensed content created using artificial intelligence. This follows a similar agreement with TikTok earlier this year, highlighting the growing importance of social media platforms for artist revenue. [Extracted from the article]
