Considering the growth potential of ultra wide band (UWB), the government revised the technical requirements in November 2022 to enable services to use the technology through mobile communication devices such as smartphones. This study estimates the economic impact of an unlicensed spectrum management policy by analyzing cases of technical requirement revisions. Through inter-industry analysis, the revision of technical requirements is expected to induce a production effect of KRW 7.1787 trillion and an added-value effect of KRW 2.2151 trillion over the next 10 years. As an unlicensed spectrum is expected to be utilized in various industrial fields, regulators are implementing active management policies. However, analyses of the contribution of these policies to the national economy are lacking. This study not only addresses this academic gap but also provides foundational data for market-based spectrum management policies based on economic feasibility. [ABSTRACT FROM AUTHOR]

The highest level of the present-day geomagnetic recordings is presented by the absolute controlled magnetic measurements. This quality is permanently fulfilled in geomagnetic observatories (GO) only. The absolute records are based on nuclear magnetometers for the intensity measurement and on DIM (Declination and Inclination Magnetometer) instruments for the direction determination of the ambient magnetic field. Although the density of GOs is not dense enough for every scientific purpose (i.e., modelling the secular variation in detail), repeat station (RS) networks were founded in a lot of countries on the Earth. Regarding to the main task of RS measurements, almost the same requirements must be fulfilled during the fieldwork as in the GOs. Consequently, the environmental and instrumental expectations are pre-defined as well as the procedure of measurement which are generally absolute readings. After the reduction of the absolute measurements to the simultaneous record of the nearest GO is performed, the data can be represented to a relevant yearly mean value.The present article shortly summarises the environmental and the instrumental background of geomagnetic absolute measurements on reoccupations of two different RS in Croatia. In 2010 tree-days-long reoccupations were performed on the selected stations with applying an on-site magnetic variometer.One of the results of data processing pointed out the appearance of a geomagnetic sea-side effect on both of RSs. The phenomenon is the geomagnetic influence of the induced current system in the seawater near to the shore. The anomalous lateral currents are the consequence of the high conductivity contrast between the mainland and the (moving) salinity water and the induction effect of the fluctuating external geomagnetic field.The calculation steps of the geomagnetic elements will be also detailed regarding the recorded samples of a presented dataset as well as the diagnostic values (i.e., offset value and misalignment error of fluxgate probe).

Purpose: Lean management is a suitable methodology for companies that want to improve their productive performance and competitiveness. This study aims to research levels of implementation and internalisation of Lean production tools in Spanish manufacturing companies, and explores differences in behaviour between SMEs and large companies based on data gathered over three time periods. The correlation between Lean adoption and company performance is also analysed. Design/methodology/approach: Company survey data for the years 2012, 2015 and 2018 collected from 354 respondents were used to conduct a longitudinal study on the level of lean tool adoption and internalisation in manufacturing companies. Findings: Over the years, the use of Lean tools has increased, whereas levels of internalisation have remained stable. Lean tool use in SMEs and large companies show significant differences in 2012 and 2015, but this is no longer the case 2018. Results also show that higher Lean tool use helps increase return on sales (ROS), and higher levels of internalisation of tools helps reduce the number of products rejected. Originality/value: To date, there are no known studies on the use and internalisation of Lean tools or their correlations with business performance indicators in Spanish manufacturing companies.

In this study, standards of high-biocontainment facilities (including laboratories and large-scale production facilities) formulated by China and other countries were analyzed and compared, and the technical points and requirements for Heating, Ventilating, and Air Conditioning (HVAC) systems in different series of standards were discussed. The main focus was on expounding the design and verification of the containment area’s indoor parameters, ventilation system, filter design, integrity test, fan standby, airflow pattern, and system reliability. This study expects suggestions and opinions on the construction and development of biosafety facilities in China and the possible future revision of relevant national standards.

Currently, there are various methods of testing vehicles and its components used by different car manufacturing companies. Also, these methods are given in the UNECE regulatory documents in the field of transport, but these documents do not take into account the separate operating conditions of cars in different regions. In this regard, the paper presents the road and climatic conditions of Central Asia characterized by peculiar characteristics. Based on the climatic features of the operation in a hot region, technical requirements have been developed for electromechanical sensors of cars for operation in hot climatic conditions, which should ensure the reliability of these components when the car runs at least 250,000 km. The method of testing electromechanical sensors of cars has been presented. It is established that in order to ensure the normal operability of sensors operating in hot climates, it is necessary to conduct tests at a nominal ambient temperature 45 ± 5 °C. The test procedure is built based on this parameter. All developed test methods are consistent with current standards in the field of electromagnetic, electromechanical and other electrical parameters of the automotive industry. Schematic diagrams of stands for testing have been given. The paper reflects the methodology of accelerated reliability tests, in which the temperature is set as the accelerating factor. The tests fully reflect the operational characteristics of the movement of cars in a sharply continental climate with a hot slope of ambient temperature with sharp temperature changes. After each test, it is determined that the nominal parameters of the sensors are checked for compliance with the established requirements. Conclusions reflecting the results of the work carried out have been made.

The availability of non-reimbursable funds for water supply networks has made the public procurement of construction work in this sector of particular interest in terms of performance. The purpose of this research is to identify key issues and patterns emerging from the engagement between Romanian contracting entities awarding such construction contracts and economic operators. The engagement is materialized through rounds of clarification requests during the offer preparation stage. Following the analysis of the specialized literature, it was found that the subject was not addressed in many scientific publications. The research undertaken was an empirical analysis of selected tenders. The research methodology focuses on the qualitative analysis of publicly available questions and responses, complemented by the analysis of numerical data relating to the same tenders. From the study, it results that a high percentage of all questions analyzed target the technical requirements of the contract notice documents. In some instances, the same questions are found in multiple tenders. Tender evaluation periods are lengthy. The tenders are published with a similar strategic profile (e.g., open tendering, no division into lots) and participation is dominated by bidder associations of multiple economic operators. This study concludes that the quality of the technical requirements does not support the type of strategic profile employed by the contracting entities. The rigidity of written communication makes it unsuitable to mitigate the negative effects of a flawed approach in developing technical requirements for high value, high complexity projects directly connected with Romania's public water supply challenges.

Modularity is often employed to increase the flexibility and adaptability of a system. A well-known issue during the design of modular systems is the emergence of ripple effects propagating throughout the system when one module is changed, which is dependent on other modules within the system. While several techniques or approaches have been proposed to mitigate these effects, they often neglect the integration and interconnection of cross-cutting concerns (i.e., functionalities that are required across different parts of the main functional dimension) within the system. This article argues that the proper integration of cross-cutting concerns is important in order to avoid ripple effects and preserve the adaptability of a modular system. Based on a set of possible integration architectures that offer different alternatives to integrate cross-cutting concerns within a modular structure, we introduce the integration design matrix (IDM) as an instrument to systematically analyze the cross-cutting concern provisioning within specific modular artifacts. A set of design guidelines is proposed to optimize the integration of the cross-cutting concerns, applicable within the context of the IDM. We illustrate our approach by means of examples in several domains. [ABSTRACT FROM AUTHOR]

Quality function deployment (QFD) has been a popular product or service development method to convert customer needs (CNs) into technical requirements (TRs). Nevertheless, the traditional QFD has vagueness inherent in experts’ opinions in determining CNs’ weights and the relationship between CNs and TRs. In the previous research works, fuzzy set theory is popular to deal with imprecise information in QFD. However, it still suffers from several deficiencies. For example, it needs prior information that leads to relatively fixed intervals expressing vagueness; and it assumes the membership degrees are crisp. To solve the issues, this article develops an integrated QFD method, where rough sets and cloud model are utilized for treating uncertain information. The former expresses impreciseness without any other assumptions and the latter considers expert evaluations’ randomness. In order to obtain more comprehensive importance of CNs, a combination weighting method is utilized. In the end, a compressor rotor's industrial service design is conducted utilizing the proposed method, where its effectiveness is verified. [ABSTRACT FROM AUTHOR]

Objectives: The online workshop on IVD regulation was performed to broaden the understanding of the technical documentation needed for IVD licensing and the strategies to asses it. Background: Testing of blood donors and donations significantly reduces the risk of transmitting transfusion‐transmissible infections. Many test systems are commercially available, but not all meet the recommended sensitivity and specificity standards. Many African countries either lack functional structures for the regulation of IVDs this poses a threat to the quality of the blood supply. Materialsand Methods: The Paul‐Ehrlich‐Institut BloodTrain organised an online workshop in September 2021 to introduce staff from several National Regulatory Authorities (NRAs) in Africa to the regulation of IVD and the technical information that need to be provided by the manufacturers of blood screening IVD. Their evaluation was trained in practical exercises. Results: This online workshop brought together over hundred participants from NRAs of 12 African countries. Speakers from PEI, Blood Train, WHO and academia, with experience in IVD regulation trained participants in the various topics addressed during this workshop. Conclusions: This workshop presented a great starting point for most participating NRAs to set up and/or strengthen their regulatory structures for IVDs. [ABSTRACT FROM AUTHOR]

Within a relatively short period of time, we have seen five distinct generations of cellular technology roll out, with each delivering enhancements in terms of quality of service (QoS) while at the same time enabling new features and services, as highlighted in. Every successive generation of wireless standards has introduced advances in data-carrying capacity and reliable low latency as well as different use cases. At first glance, we may expect that the evolution is driven by the insatiable and ever-increasing demand for capacity, where a year-on-year growth of global mobile network data traffic is in excess of 40%. The traffic growth is primarily driven by both the rising number of smartphones and subscriptions and an increasing average data volume per subscription. However, as we start to look deeper, we see a much more intricate set of requirements and complexities that intertwine: the applications, technical requirements, and radio technology developments. The evolution could not have happened were it not enabled by a parallel evolution in cellular base station technology to support more spectrum, better spectral efficiency, and network densification.

Over the last few years, the number of grid-connected photovoltaic systems (GCPVS) has expanded substantially. The increase in GCPVS integration may lead to operational issues for the grid. Thus, modern GCPVS control mechanisms should be used to improve grid efficiency, reliability, and stability. In terms of frequency stability, conventional generating units usually have a governor control that regulates the primary load frequency in cases of imbalance situations. This control should be activated immediately to avoid a significant frequency variation. Recently, renewable distribution generators such as PV power plants (PVPPs) are steadily replacing conventional generators. However, these generators do not contribute to system inertia or frequency stability. This paper proposes a control strategy for a GCPVS with active power control (APC) to support the grid and frequency stability. The APC enables the PVPP to withstand grid disturbances and maintain frequency within a normal range. As a result, PVPP is forced to behave similar to traditional power plants to achieve frequency steadiness stability. Frequency stability can be achieved by reducing the active power output fed into the grid as the frequency increases. Additionally, to maintain power balance on both sides of the inverter, the PV system will produce the maximum amount of active power achievable based on the frequency deviation and the grid inverter's rating by working in two modes: normal and APC (disturbance). In this study, a large-scale PVPP linked to the utility grid at the MV level was modeled in MATLAB/Simulink with a nominal rated peak output of 2000 kW. Analyses of the suggested PVPP's dynamic response under various frequency disturbances were performed. In this context, the developed control reduced active power by 4%, 24%, and 44% when the frequency climbed to 50.3 Hz, 50.8 Hz, and 51.3 Hz, respectively, and so stabilized the frequency in the normal range, according to grid-code requirements. However, if the frequency exceeds 51.5 Hz or falls below 47.5 Hz, the PVPP disconnects from the grid for safety reasons. Additionally, the APC forced the PVPP to feed the grid with its full capacity generated (2000 kW) at normal frequency. In sum, the large-scale PVPP is connected to the electrical grid provided with APC capability has been built. The system's capability to safely ride through frequency deviations during grid disturbances and resume initial conditions was achieved and improved. The simulation results show that the given APC is effective, dependable, and suitable for deployment in GCPVS. [ABSTRACT FROM AUTHOR]

The fifth generation (5G) of wireless networks promises to meet the stringent requirements of vehicular use cases that cannot be supported by previous technologies. However, the stakeholders of the automotive industry (e.g., car manufacturers and road operators) are still skeptical about the capability of the telecom industry to take the lead in a market that has been dominated by dedicated intelligent transport systems (ITS) deployments. In this context, this paper constructs a framework where the potential of 5G to support different vehicular use cases is thoroughly examined under a common format from both the technical and business perspectives. From the technical standpoint, a storyboard description is developed to explain when and how different use case scenarios may come into play (i.e., pre-conditions, service flows and post-conditions). Then, a methodology to trial each scenario is developed including a functional architecture, an analysis of the technical requirements and a set of target test cases. From the business viewpoint, an initial analysis of the qualitative value perspectives is conducted considering the stakeholders, identifying the pain points of the existing solutions, and highlighting the added value of 5G in overcoming them. The future evolution of the considered use cases is finally discussed.

Abstract Background Implementing the health information system (HIS) is more complex and costly than implementing other information systems. The present study was conducted to design and evaluate technical requirements for the HIS. Methods The present study was conducted in 2016 by determining technical requirements for the HIS using the Delphi technique and then evaluating this system using a checklist based on the approved requirements. Results The first part of the study designed a 73-item final list of technical requirements for the HIS in four domains, i.e. communication service, system architecture, security service and system response time. The evaluation results obtained in the second part showed that communication service was met in 63.8% of the HIS programs, system architecture in 65.5%, security service in 72.4% and system response time in 76.3%. Conclusions A technical evaluation tool was designed and used to select and evaluate the HIS. The evaluation results suggested the study HIS was poorer in terms of communication service and system architecture than in the other two dimensions.

Requirements represent the first opportunity for mistakes in an engineering effort and their effects are felt downstream in the form of increased costs and schedule overruns. Many of the innovations and revolutions to systems engineering have omitted changing requirements and instead assume them as intrinsic components to the process. Perhaps this is due to a lack of understanding in the purpose and history of requirement statements. This article establishes a theoretical basis for requirements based on primary source research that describes their use to solve problems and maintain accountability. That theoretical basis is applied to construct a historical basis for requirement statements that shows there has been very little change to the use or formatting in almost 200 years. This lack of innovation is confirmed in an analysis of a series of definitions from a leading systems engineering guideline. By establishing a theoretical and historical basis for requirement statements, this research sets a foundation for future innovations, such as the use of other media beyond the natural language text-based requirements of today, to enable more efficient development of more effective systems.

In the last few years, LIBS has become an established technique for the assessment of elemental concentrations in various sample types. However, for many applications knowledge about the overall elemental composition is not sufficient. In addition, detailed information about the elemental distribution within a heterogeneous sample is needed. LIBS has become of great interest in elemental imaging studies, since this technique allows to associate the obtained elemental composition information with the spatial coordinates of the investigated sample. The possibility of simultaneous multi-elemental analysis of major, minor, and trace constituents in almost all types of solid materials with no or negligible sample preparation combined with a high speed of analysis are benefits which make LIBS especially attractive when compared to other elemental imaging techniques. The first part of this review is aimed at providing information about the instrumental requirements necessary for successful LIBS imaging measurements and points out and discusses state-of-the-art LIBS instrumentation and upcoming developments. The second part is dedicated to data processing and evaluation of LIBS imaging data.

This paper presents the result of the application of the technical requirements for voice performance on 6 selected voice major students of the Department of Music, University of Nigeria, Nsukka, having noted the problem of poor professional performance by voice performance students. This was done in order to find out how proper training on the technical requirements for voice performance can bring about positive output in the teaching and learning of Voice and voice performance. The participants were six randomly selected voice major students from the diploma one class of the Department of Music, University of Nigeria, Nsukka, who were exposed to the learning process for eight weeks. The diploma students were used for this study to ensure the avoidance of involving voice students that are already used to a particular teaching method for voice. Random selection of the students was also done to avoid bandwagon result from the exercise. Data for the work included secondary sources, participant journals, group and individual interviews. Findings suggest that a successful career in voice performance can be achieved when the technical considerations involved in singing are studied and carefully adhered to. [ABSTRACT FROM AUTHOR]

The technical requirements and hygiene standards for the buildings and internal building installations of the medical establishments provided in various normative documents are considered. Fulfilment of these requirements would increase the readiness of medical institutions to isolate a (suspected) patient with an airborne infection (such as Severe Acute Respiratory Syndrome and/or COVID-19), in order to prevent the spread of infection among staff, other patients and visitors, especially those with reduced immunity or falling into another risk group vulnerable to various pathogens transmitted in the hospital environment. We mainly focus on the Ordinance No. RD-02-20-3 of the Ministry of Regional Development and Public Works of 21/12/2015 for design, implementation and maintenance of public service buildings in the field of education and science, healthcare, culture and arts, as well as the Medical Standard on prevention and control of hospital-acquired infections, approved by the Ordinance No. 3 of 08/05/2013 of the Ministry of Health. Adjustment of isolation rooms or parts of buildings of medical institutions in the country to the cited requirements would increase their readiness for early response in epidemic situations related to airborne infections.

The highest level of the present-day geomagnetic recordings is presented by the absolute controlled magnetic measurements. This quality is permanently fulfilled in geomagnetic observatories (GO) only. The absolute records are based on nuclear magnetometers for the intensity measurement and on DIM (Declination and Inclination Magnetometer) instruments for the direction determination of the ambient magnetic field. Although the density of GOs is not dense enough for every scientific purpose (i.e., modelling the secular variation in detail), repeat station (RS) networks were founded in a lot of countries on the Earth. Regarding to the main task of RS measurements, almost the same requirements must be fulfilled during the fieldwork as in the GOs. Consequently, the environmental and instrumental expectations are pre-defined as well as the procedure of measurement which are generally absolute readings. After the reduction of the absolute measurements to the simultaneous record of the nearest GO is performed, the data can be represented to a relevant yearly mean value. The present article shortly summarises the environmental and the instrumental background of geomagnetic absolute measurements on reoccupations of two different RS in Croatia. In 2010 tree-days-long reoccupations were performed on the selected stations with applying an on-site magnetic variometer. One of the results of data processing pointed out the appearance of a geomagnetic sea-side effect on both of RSs. The phenomenon is the geomagnetic influence of the induced current system in the seawater near to the shore. The anomalous lateral currents are the consequence of the high conductivity contrast between the mainland and the (moving) salinity water and the induction effect of the fluctuating external geomagnetic field. The calculation steps of the geomagnetic elements will be also detailed regarding the recorded samples of a presented dataset as well as the diagnostic values (i.e., offset value and misalignment error of fluxgate probe)., (© 2024 The Author(s).)

The article illustrates a theoretical research path and project experimentation on post-disaster temporary housing modules in order to verify if and how the temporary dimension of the intervention is strategic for the implementation of the transition towards reconstruction, and in line with requests for environmental sustainability. After a brief introduction on the critical issues and opportunities of temporary living in post-disaster reconstruction processes, the article describes the results of some theoretical and application research, and the effects on technical control tools in recent civil protection emergencies in Italy. In conclusion, the article proposes some useful considerations for the definition of strategic and sustainable planning connected to the temporal dimension of the post-disaster reconstruction interventions.

Technical requirements of geometry, construction and manufacturing methods of toothed gears of transmissions of electric motor cars are given. It is shown, that the drive type is defined not only by design requirements: the kinematic scheme of the drive, transmitted power, velocities of operation, fatigue life, reliability, etc., but also by technological requirements taking into account applied gear machinery. The special attention is paid to the reasonable choice of a brand of the sparingly alloyed steels and to requirements of their metallurgical quality in conditions of deliveries.

Social interest housing (VIS, in Spanish) and priority interest housing (VIP, in Spanish) programs have been promoted in Colombia to provide affordable housing to low-income households. Currently, in addition to the Colombian Seismic Resistant Construction Regulations, last updated in 2010 (NSR-2010), there are other mandatory construction regulation that have been issued after 2010, producing an additional cost per square-meter of constructed area and exceeding the maximum limits established for these types of residential projects. Adjust the project to the established limits result in area reduction of the areas and quality of construction finishes of the final product. In this research, historical statistics of the construction costs of VIS and VIP in Cali are reviewed, and the impact on the cost of these housing types with respect to the inclusion of new technical dispositions is evaluated. The results reveal that the established maximum values for these types of projects must be adjusted due to the fact that the new standards must be incorporated.

Water quality is subject to judgement by three components: the protection of public health, public acceptance and impact on the acceptability and durability of facilities. In modern times, extraction of water resources before they are restored with a lack of discipline and regulations for efficient management of pollutants and protection of water has accelerated the deterioration of water quality and has caused unwanted changes in water resources. However, the social demand regarding the issue of water quality has extended beyond being healthy and having effect on public to areas of social satisfaction and facility protection. In such circumstances, water sanitation units in water companies will not be able to meet the demand of the public on the issue of water quality with traditional structure inspired by health institutions which judges the quality of water on aspects of its effect on the public health, so it is necessary for them to replace "water hygiene" model with "water quality engineering" model, considering the favorable idealistic horizon and having an evolutionary view. In this model, water quality engineer presents the best and most accurate inferences with a complete knowledge of the scientific principles and with the requirements of adaptive management, from raw data, laboratory indicators of efficient management, extraction and taking into account economic orders, risk assessment and technical and social requirements. Giving his opinion in decisions related to designing treatment processes and structures, storage and transport of water and selection of materials, he realizes the idea of engineering water quality.

The officers were warm to patients, doctors always heard complaints and stories of patients, pharmacy officers always prayed for patients to get well soon. [ABSTRACT FROM AUTHOR]

This paper focuses on the bidding strategy and online control methodology of battery storage systems (BSS) to participate in the frequency containment reserve (FCR) market. The new technical requirements for the FCR markets in the Nordic power system does not allow controlling the BSS in other ways than on the basis of frequency. Therefore, control mechanisms such as recovering the state of charge (SOC) whenever the power system frequency is in its acceptable (dead-band) range cannot be used. In this regard, this paper proposes and compares different control mechanisms to recover the SOC that are in line with the new regulation and maximizes the BSS profit using the lifetime model of the BSS. In order to compare different control mechanisms, this paper investigates the behaviour of a large BSS unit installed in the Helsinki area by simulating the proposed strategies over measured frequency and market data from 2014 till 2019.

Background: Implementing the health information system (HIS) is more complex and costly than implementing other information systems. The present study was conducted to design and evaluate technical requirements for the HIS.Methods: The present study was conducted in 2016 by determining technical requirements for the HIS using the Delphi technique and then evaluating this system using a checklist based on the approved requirements.Results: The first part of the study designed a 73-item final list of technical requirements for the HIS in four domains, i.e. communication service, system architecture, security service and system response time. The evaluation results obtained in the second part showed that communication service was met in 63.8% of the HIS programs, system architecture in 65.5%, security service in 72.4% and system response time in 76.3%.Conclusions: A technical evaluation tool was designed and used to select and evaluate the HIS. The evaluation results suggested the study HIS was poorer in terms of communication service and system architecture than in the other two dimensions. [ABSTRACT FROM AUTHOR]

Systems engineering traditionally approaches the design of systems through determination of requirements for and implementation of a system. The system is conceived as something to enable achievement of an effect with the tacit assumption that the system to be designed must achieve technical performance, including availability characteristics, which enable delivery of the whole of the intended effect. This approach determines the technical requirements of the system to ensure achievement of the system purpose under assumptions about how the system, or fleet, would be deployed to provide the intended service. Usually, cost is addressed after requirements, either to find the cheapest method to achieve the requirements or as one dimension of a trade-space analysis. In this paper, we explore a different philosophy for finding the system requirements; starting with the required system level service provision, but agnostic about the technical quality needed. We investigate a trade-space including the life cycle cost (LCC) of service provision as a contribution to determining subsystem requirements. We model the life cycle, for many variations of technical composition, using a Monte Carlo method, and show that a trade-space of LCC and requirements is likely to produce a cheaper solution than starting with sub-system requirements.

Let $q$ be a prime power and $\mathbb {F}_{q}$ be the finite field of size $q$. In this paper we provide a Galois theoretical framework that allows to produce good polynomials for the Tamo and Barg construction of optimal locally recoverable codes (LRC). Using our approach we construct new good polynomials and therefore optimal LRCs with new parameters. The existing theory of good polynomials fits entirely in our new framework. The key advantage of our method is that we do not need to rely on arithmetic properties of the pair $(q,r)$ , where $r$ is the locality of the code. [ABSTRACT FROM AUTHOR]
