This paper presents the development of an intelligent bicycle system with automatic gear shifting based on the user’s physiological information and environment sensing. The sensor data are collected during the ride, uploaded to the cloud database, and analyzed using random forest to derive the appropriate riding requirement. Our proposed technique performs the automatic gear shifting operation using inexpensive sensor components and embedded system development boards. The gear shifting module is designed and installed as an external device for the off-the-shelf bicycle, without the need to dismantle or modify the body structure. A bicycle riding specific online management interface is developed for web access and administration. It allows the cloud data being displayed and let users acquire and understand their riding behaviors. The experiments and evaluation in the outdoor environment have demonstrated the feasibility of the proposed intelligent gear shifting system.

An important area for applying self‐adaptation that emerged around 2010 is the Internet‐of‐Things (IoT). This chapter introduces an IoT application for building security monitoring, called DeltaIoT. DeltaIoT consists of a collection of 15 nodes that are connected through a wireless network. It uses multi‐hop wireless communication and offers a management interface for system operators to collect data about the network and set the network parameters. The chapter considers two primary types of uncertainty in DeltaIoT: network interference and noise; and fluctuating traffic load. It presents the quality requirements for DeltaIoT defined by the stakeholders. The key problem of DeltaIoT is how to ensure the quality requirements of the system regardless of the uncertainties in the IoT network caused by network interference and the fluctuating traffic load of packets. A typical approach used in practice to deal with such uncertainties in IoT applications is to over‐provision the network.

Intersection management of Connected Autonomous Vehicles (CAVs) has the potential to improve safety and mobility. CAVs approaching an intersection can exchange information with the infrastructure or each other to schedule their cross times. By avoiding unnecessary stops, scheduling CAVs can increase traffic throughput, reduce energy consumption, and most importantly, minimize the number of accidents that happen in intersection areas due to human errors. We study existing intersection management approaches from following key perspectives: (1) intersection management interface, (2) scheduling policy, (3) existing wireless technologies, (4) existing vehicle models used by researchers and their impact, (5) conflict detection, (6) extension to multi-intersection management, (7) challenges of supporting human-driven vehicles, (8) safety and robustness required for real-life deployment, (9) graceful degradation and recovery for emergency scenarios, (10) security concerns and attack models, and (11) evaluation methods. We then discuss the effectiveness and limitations of each approach with respect to the aforementioned aspects and conclude with a discussion on tradeoffs and further research directions.

As the complexity of Internet of Things (IoT) systems increases, a large variety of tools and technologies for IoT management are making their way into both research setups and the market. IoT management solutions must consider the resource restrictions of embedded devices, as well as their heterogeneity and network dynamics. With these in mind, the Internet Engineering Task Force developed several standards targeting the integration and interoperation of heterogeneous devices, such as the Representational State Transfer Configuration Protocol (RESTCONF) or the Constrained Application Protocol (CoAP) Management Interface. Concurrently, the Open Mobile Alliance developed the Lightweight Machine-to-Machine protocol, for IoT device management. This paper provides a comprehensive, up-to-date overview of IoT management technologies, frameworks and protocols. Also, it proposes a taxonomy for IoT devices management. In addition to presenting the various solutions, the paper provides comparative views, standardization timeline, and market analysis. The presented analysis ranges from traditional network management protocols, such as Simple Network Management Protocol, to the newest IoT management and configuration protocols, such as CoAP Management Interface and Lightweight Machine-to-Machine protocols. Moreover, this survey identifies remaining challenges and solutions offered by recent management protocols, not covered by previous surveys.

With the rapid development of the stereo garage, there are plenty of security problems appeared in stereo garage. The monitoring and management system of the stereo garage has attracted more and more attention. A cloud monitoring and management system for stereo garage is designed based on Web technology, which collects real-time data from the intelligent controller of the stereo garage, stores them in the cloud database. History and real-time data are studied to complete the functions of garage overview, real-time video monitoring, fault management, garage management, and system management. Deep confidence networks are proposed to conduct fault diagnosis for stereo garage, and the results are sent to the management interface of cloud portal (APP and website) for remote management. Test results show that the management efficiency of the stereo garage is significantly improved. The system guarantees the safe and reliable work of the stereo garage. It achieves better performance especially in the remote management and fault diagnosis.

Water being an essential commodity is stored at several locations such as buildings, offices domestic households, hospitals smart homes and specifically in industries in tanks. Any place where individuals live and carry out life processes, water plays a major role. Ensuring the proper usage and non-wastage of water is an obligation on every individual. This water is generally used for cleaning, daily use, and surgical instruments, sanitizing in the case of the medical field, manufacturing products, and even cooling of heavy machinery. Such large-scale applications, especially in industries like dairy, wastewater disposal, manufacturing, and food processing, impose documenting the levels of water from various tanks to keep track of the water levels used, cost usage, and generate warnings in the occurrence of any water wastage. This necessitates a sophisticated user interface that is both interactive and effective, for both the industrialists and the labour force. This project puts forth a solution to this stipulation. It consists of a front panel that shows each of the water monitoring system's controls and indicators, a report generation system, and a cloud server that incorporates the entire industrial monitoring system allowing it to be accessed remotely from anywhere on the planet. The framework is built with a graphical programming tool that employs function blocks as well as API keys to connect the cloud to the user interface. LabVIEW is a powerful tool for implementing this device on a desktop or in an industrial water management interface. LabVIEW is a versatile platform that can be used for real-time applications and used in combination with numerous high-quality industrial equipment. The framework of this project is configured to take into account the date, period, and consumption hours with a daily and monthly overview of the different locations of the tanks, and is interpreted and extracted in a LabVIEW VI based on the information requested by the user. A report is produced for the entire time period and records the data over a month. In addition to this function, the device can be remotely supervised through the cloud, and the overflow of the water sends warnings to the user based on the threshold set to avoid excessive loss of water. According to estimates, introducing such a water management scheme has supported industries and households in minimizing their water use, and decreasing costs by three times, making it efficient for the owners, and the government while also ensuring environmental sustainability.

The virtual customer premises equipment (VCPE) is a virtual Computing platform, capable of to host simultaneous and dynamically provisioned virtual network functions (VNFs), the VCPE has become an important element in SD-WAN and Edge Computing. Notwithstanding the SDWAN points to new management solutions (such as, gRPC-Network Management Interface, or RestConf), the basic management tasks, namely monitoring, and simple configuration, still the same. In this interim of coexistence between traditional WAN and SD-WAN, the maturity, the past investments, and dominance of Internet management solutions, suggest that it would be quite interesting for the operators to extend their legacy Internet management solutions till VCPE and SD-WAN get their maturity. This paper presents the DynagentX, a VCPE internal management instrumentation’s architecture, aiming to adapt the Internet management framework to the SD-WAN, and edge computing scenario, focusing the VCPE. In this work I show results that substantiate the proposal feasibility, performance, and security.

With the development of the Internet of Things (IoT), it has been widely deployed. As many embedded devices are connected to the network and massive amounts of security-sensitive data are stored in these devices, embedded devices in IoT have become the target of attackers. The trusted computing is a key technology to guarantee the security and trustworthiness of devices’ execution environment. This paper focuses on security problems on IoT devices, and proposes a security architecture for IoT devices based on the trusted computing technology. This paper implements a security management system for IoT devices, which can perform integrity measurement, real-time monitoring and security management for embedded applications, providing a safe and reliable execution environment and whitelist-based security protection for IoT devices. This paper also designs and implements an embedded security protection system based on trusted computing technology, containing a measurement and control component in the kernel and a remote graphical management interface for administrators. The kernel layer enforces the integrity measurement and control of the embedded application on the device. The graphical management interface communicates with the remote embedded device through the TCP/IP protocol, and provides a feature-rich and user-friendly interaction interface. It implements functions such as knowledge base scanning, whitelist management, log management, security policy management, and cryptographic algorithm performance testing.

the mass individualization in training communities and education is the next big development in the system of education. In the contemporary world, this school of thought and practice is generally accepted in most education systems across the world where the performance of the students is enhanced via the available numerous e-learning platforms to fit various individual requirements. The e-learning platforms have allowed the students to get the knowledge as dictated by their passion and talents. Putting the interest of the students at heart while creating the e-learning platform has not only enabled success in the performance in class but has also enabled an interactive session with the various stakeholders who are keen to understand the very context of talent growth. Through analysis of many studies, this excerpt investigates the various pedagogical approaches to distance education techniques like the micro-conforming methods, the macro accommodative approaches, personalized adaptive education systems, the constructivism approaches, and the aptitude management interface methodologies.

Real-time traffic video streaming, such as roadside surveillance and aerial video, has been widely used in traffic monitoring nowadays. However, most of the traditional traffic data collection methods lack mobility that can only collect macroscopic data. In this paper, an intelligent traffic monitoring system based on an open source cooperative platform called SAGE2 was developed. Based on the integrated big screen TV wall of SAGE2, a map-based aerial traffic video streaming management interface was designed. In the image pre-processing section, it provides functions such as lens distortion removal, top view projection transforms, and video stabilization; simulate video streaming to provide instant and long-term micro-flow data collection. Micro-traffic flow data provides high-resolution information both in time and space which can be used to analyze the driving behavior of individuals and the public. Combined with the lane level map, it can provide a variety of visual vehicle flow presentations, such as intersection traffic distribution that can also be used to develop an innovative application in the future.

We envision a combinative use of an AR headset and a smartphone in the future that can provide a more extensive display and precise touch input simultaneously. In this way, the input/output interface of these two devices can fuse to redefine how a user can manage application windows seamlessly on the two devices. In this work, we conducted a formative interview with ten people to provide an understanding of how users would prefer to manage multiple windows on the fused interface. Our interview highlighted that the desire to use a smartphone as a window management interface shaped users' interaction practices of window management operations. This paper reports how their desire to use a smartphone as a window manager is manifested.

This paper details the working methodology of the cyber attackers and define a sample strategy that can be used to deter, detect, and successfully defend against this kind of attack. The concept of the cyber kill chain will be discussed and mapped to the relevant stages of the broadcast chain. Any device that has an internet protocol management interface is susceptible of command and control by an unauthorized user. Following the recent hacks of U.S. radio stations in the Republican heartland that successfully aired a song against Donald Trump, the hacking of Channel 2 in Israel for politically motivated reasons, and the TV5 attack, broadcasters need to pay more attention to the cyber security of the broadcast network. Attacks come from far and wide; however, when the methodology used in attacks is analyzed, it is very similar to that used in other industries from which we can learn lessons to prevent any negative impact on our operations. Attacks come from far and wide; however, when the methodology used in attacks is analyzed, it is very similar to that used in other industries from which we can learn lessons to prevent any negative impact on our operations.

The vision of self-managing software systems was proposed in the past two decades. We argue that to be able to realize such vision, a suitable machine consciousness computational model must be incorporated into the software design, as it will be responsible for all cognition, thinking, learning, planning, and decision making tasks. Currently, there exist many general computational models for machine consciousness that could be adopted. They differ in their complexity and their definition of what consciousness is. Therefore, in this paper, we propose to offer machine consciousness as a service (MCaaS). This enables any software system to become “self-managing” by loosely coupling itself with the MCaaS service via a suitable management interface. We propose a roadmap for building such MCaaS service as a composite web service, adopting the Starzyk–Prasad machine consciousness computational model.

Heart failure is long-lasting and progressive, i.e., life-threatening, and leads to death. The patients with Heart Failure (HF) are subjected to medical observation for their remaining days. In this paper, we have presented a Medical Decision Support System (MDSS) for the examination of Heart Failure patients for providing various outputs such as HF Criticality Assessment, HF type prediction and a management interface that compares with different patient reports. The proposed system composed of a portion of Intelligent Core and one HF special-purpose management tool. The management tool offers the function to act as an interface the usage of Artificial Intelligence and its training. We followed a Machine Learning (ML) method to implement smart intelligent roles. Here we have related the performance of a system with fuzzy rules that are produced inherently, neural networks, Random Forest algorithm, and Support Vector Machine (SVM) for analyzing our database. Comparison of HF Criticality Assessment and Type predictions are evaluated by using Random Forest Algorithm. The management tool permits the cardiologist to reside on a supervised database that is appropriate for Machine Learning during his daily consultation. The Machine Learning system automatically provides a readable output based on the condition of the patient that can be understandable by other doctors and even nurses.

This paper presents an IntelliBike with automatic shifting based on the riding condition. It is able to collect and transmit multiple sensor data to the cloud database, and the real-time sensor information is used to analyze for an appropriate riding state through random forest. Our technique performs automatic gear shifting using inexpensive sensor components and embedded system development board, which is not available in current expensive electronic shifting systems. The function and the installation of the external components can be carried out on the off-the-shelf bicycle with a shifting line, without the need to dismantle or modify the basic equipment. The system also includes an IntelliBike-specific online management interface that allows all cloud data to be displayed and let users access and understand their riding conditions.

In this work, the database was designed and implemented in accordance with the requirements of the relational model, which ensures the storage and collective access to the information of the auto-filling system and CMS WordPress data. Algorithms of system functioning were developed, the order of interaction of classes during program code execution was determined, as a result of which the application was implemented. Template Method architectural pattern was chosen to implement the web-based automatic content filling system. The following tools and technologies were selected to create the software package HTML markup language for HTML documents; programming language PHP; MySQL database management environment; Apache web server; the OpenServer package. The algorithms of the basic processes of content filling automation were considered and the interaction of the system classes during the processes of parsing, filtering and storing of information were analyzed. The developed system does not require specialized hardware, additional settings and deployment tools other than the standard ones for such plugins. This application is mostly for the site administrator and does not have user interface. That is why the features of the plugin automation system configuration interface; RSS feeds view and management interface, as well as the RSS feed configuration interface are described in detail. In the future, this system can be improved by introducing new functionality and improving the algorithm for reading data.

With the increasing demand for distributed generators (DGs), the grid-connection of DGs has become an important issue. In order to connect to gird friendly, and effectively control and manage DGs, in the paper, an adaptive protecting and monitoring management interface device of grid-connected DGs is proposed. Firstly, based on the operation of DGs, the management device can adaptively complete the functions of protection, monitoring and communication management in accordance with wide time scale and frequency. In the actual testing, the proposed strategy can not only enhance the timeliness of data utilization and the accuracy of control, but also improve the security and stability of DGs and other devices. In addition, the solution can optimize the allocation of power and the fault-tolerant protection capability of the device.

In the paper, we present the framework to offload VNF's data plane to the cloud infrastructure by leveraging the capabilities of P4. This approach allows tenants to run data plane functions directly on the programmable switches. Moreover, we propose the P4-based VNF offloading management interface as the extension to the DPPx framework - the target-independent P4 plugin for OpenStack.

Scaling up the software system on service robots increases the maintenance burden of developers and the risk of resource contention of the computer embedded on robots. As a result, developers spend much time on configuring, deploying, and monitoring the robot software system; robots may utilize significant computer resources when all software processes are running. We present Rorg, a Linux container-based scheme to manage, schedule, and monitor software components on service robots. Although Linux containers are already widely-used in cloud environments, this technique is challenging to efficiently adopt in service robot systems due to multi-tasking, resource constraints and performance requirements. To pave the way of Linux containers on service robots in an efficient manner, we present a programmable container management interface and a resource time-sharing mechanism incorporated with the Robot Operating System (ROS). Rorg allows developers to pack software into self-contained images and runs them in isolated environments using Linux containers; it also allows the robot to turn on and off software components on demand to avoid resource contention. We evaluate Rorg with a long-term autonomous tour guide robot: It manages 41 software components on the robot and relieved our maintenance burden, and it also reduces CPU load by 45.5% and memory usage by 16.5% on average.

Desktop virtualization, which is to make the desktop virtual so that users can access any application through the network with any devices at any time and any place, is being widely used now as an emerging trend. However, it is important to further improve this approach while maintaining good user experience. Though the simple protocol for independent computing environments as a virtual desktop solution can achieve a user experience similar to an interaction with a local machine, there are still many deficiencies in it. For instance, it cannot apply to environment of high controllability of user, and the quality of graphic interactive experience is to be improved. In this paper, to meet QoE requirements of user, we build a feasible file transfer and sharing mechanism and propose a graphics subsystem optimization strategy based on simple protocol for independent computing environments SPICE, namely Transparent Desktop. We also verify that the Transparent Desktop can provide users with ubiquitous desktop services of higher efficiency, stronger user-controllability and better QoE through the experimental.

Modeling and simulations are important methods in environmental research. Currently, massive simulation resources from different domains have been developed to simulate various dynamic phenomena and processes to address different environmental problems. These heterogeneous simulation resources (e.g., models, data, and servers) can be wasted if they are not shared and reused effectively. Recently, experts may exchange resources and conduct simulations in the open web environment via these shared and distributed services. However, some challenges remain, such as the heterogeneity and reusability of simulation resources. The goal of this study was to analyze typical scenarios involved in simulation tasks and design a set of service-oriented interfaces for different simulation resources. These interfaces, including the model description interface, model encapsulation interface, server management interface and sim-task operation interface, can be used to describe, encapsulate, manage and invoke environmental simulation resources, which can further contribute to resource assembly for environmental simulation tasks. This study evaluated the case of PM2.5 concentration distribution simulation by meteorological data, land cover data and a random forest model in 2014. Using the designed interface, this study conducted the simulation and explored the influence of different interpolation methods (inverse distance weighting (IDW) and kriging) for meteorological data in the random forest-based PM2.5 concentration simulation. For this case, the results show that kriging is a more suitable interpolation method than IDW for meteorological data in the simulation, and this interface design can organize simulation resources, configure tasks, and balance task loads in different servers on the open web.

The issue of distribution of large amounts of information on server stations is researched. The analysis of existing methods for distributing data of heavily loaded web applications is carried out. A system for computing load distribution using a balancing server is proposed. A description of the software necessary for the functioning of the system and server management interface is provided.

Many businesses prefer to run their web application in a cloud, as this provides an access to large numbers of computing and storage resources. To run a web application in a cloud, a virtual environment with the corresponding technology stack has to be created. The interfaces provided by cloud services (Amazon Web Services, Microsoft Azure, etc.) require micromanagement of all individual components. This makes the management of technology stacks an extremely time consuming and complex task, which involves a high degree of expertise. We present here SMI, a stack management interface that let you think about your cloud infrastructure as stacks of cloud technologies and enables moderately experienced users to manage the stacks as a whole.

The design uses PHP to realize the graphical campus network management interface, and finally presents a complete campus network management system through Web page. The system will bring convenience on network management and maintenance for the administrator.

The rise in number and complexity of Internet of Things (IoT) devices and networks has led to a profusion of tools and technologies that aim to facilitate IoT management. These management solutions must consider the resource restrictions of embedded devices, their heterogeneity and network dynamics. In this context, the Internet Engineering Task Force (IETF) engaged itself in an effort to develop standards that allow for the integration and interoperation of heterogeneous devices, such as RESTCONF and CoMI (CoAP Management Interface). On the other hand, the Open Mobile Alliance (OMA) is developing a protocol for IoT device management named Lightweight Machine-to-Machine (LwM2M). This paper provides an overview of management protocols for IoT devices. The presented analysis ranges from traditional network management protocols, such as Simple Network Management Protocol (SNMP), to the newest protocols used for management and configuration of IoT devices, such as the already mentioned CoMI and LwM2M protocols. In addition, this paper also provides an analysis of the challenges of IoT device management.

Currently gamification is being extended as a methodology to create learning courses.

According to the results of the rewinding analysis, the system indeed can promote the sewage treatment knowledge to the visitors. Most of the visitors feel the system is interesting and useful.

Cyber-attacks and breaches are often detected too late to avoid damage. While "classical" reactive cyber defenses usually work only if we have some prior knowledge about the attack methods and "allowable" patterns, properly constructed redundancy-based anomaly detectors can be more robust and often able to detect even zero day attacks. They are a step toward an oracle that uses knowable behavior of a healthy system to identify abnormalities. In the world of Internet of Things (IoT), security, and anomalous behavior of sensors and other IoT components, will be orders of magnitude more difficult unless we make those elements security aware from the start. In this article we examine the ability of redundancy-based anomaly detectors to recognize some high-risk and difficult to detect attacks on web servers---a likely management interface for many IoT stand-alone elements. In real life, it has taken long, a number of years in some cases, to identify some of the vulnerabilities and related attacks. We discuss practical relevance of the approach in the context of providing high-assurance Web-services that may belong to autonomous IoT applications and devices.

Within the MEDNET project “Mediterranean Network for Custom Procedures and Simplification of Clearance in Ports” funded by the MED programme (2007–2013), Taranto Port Authority (TPA) in Italy has designed and developed newly automatic system (prototype) for an effective and seamless management of port operators enrolment and access in the port area. Taranto Port Authority developed and tested an effective Information Technologies (IT) based on a multi-user management tool with a single interface for all port operators. The interface is based on functionalities coming from the integration and re-engineering of two different procedures managed by TPA: 1) enrolment in the TPA's Register foreseen in art. 68 of the Italian Navigation Law, mandatory for all private companies and individuals operating in the port; 2) the procedure of issuing of passes for vehicles and people to enter in the port area. The scope of this initiative was to re-engineer the two aforementioned procedures into a single IT based procedure with a single management interface. It enables to accelerate the process for passes release as well as to improve port accessibility by reducing the number of potential errors and transforming the nature of the procedure from “preventive” to “fact-finding”. In this way, the port community of Taranto will be able to provide relevant services in less time. The prototype is able to speed up the issuing of passes for persons and vehicles entering in the port area by reducing the time needed to check documents provided by companies as well as informing relevant authorities. The developed prototype enables to automatically manage different categories of passes for entering in the port of Taranto: annual passes, provisional passes as well as visitors passes. The combined effect of the new local regulation (TPA's Ordinance no. 04/14 of April 28th 2014) and the prototype enables to issue passes in 7–8 days against the previous 60 days required to complete (annual) pass request procedure. The benefits in terms of time saving have been also achieved for the other categories of passes (provisional and visitors). The prototype leads to seamless procedures management as well as to simplification of checks in entering in the port area. Streamlining procedures enables not only a reduction in terms of needed time for regular control of requests, but also a real-time control of the handled requests in parallel with the traditional ways (paper protocols). Taranto Port Authority as well as the other competent bodies are now able to check each single person and vehicle accessing in the port of Taranto, improving actual procedure and related controls, through an efficient check-in/check-out reporting. Seamless administrative formalities related of both companies’ enrolment and passes requests enable to reach an overall improvement of port accessibility and transit of vehicles and goods in the area, positively affecting its competiveness as well as quality of provided added-value services. The prototype is able to significantly reduce relevant administrative and bureaucratic aspects. Simplification of the procedures is expected to positively influence the door-to-door transport time and costs for business accessing and circulating in the port area and beyond.

As "working with a browser" continues to gain acceptance, an emerging strategy adopted by software companies is to provide a Web version of their applications previously developed in a desktop environment.

In recent years, adoption of cloud computing for computational needs is growing significantly due to various factors such as no upfront cost and access to latest service. In general, cloud infrastructure providers offer a wide range of services with different pricing models, instance types and a host of value-added features. Efficient selection of cloud services constitutes significant management challenges for cloud consumer, which is tedious and involves large information processing. To overcome this, the cloud brokers provide resource provisioning options that ease the task of choosing the best services based on consumers requirements and also provide a uniform management interface to access cloud services. This paper proposes a novel cloud brokering architecture that provides an optimal deployment plan for placement of virtual resources in multiple clouds. The objective of the deployment plan is to select the best cloud services with optimal cost, taking into account various attributes defined in service measurement index (SMI) with additional physical and logical constraints. The proposed cloud brokering architecture has been modeled using mixed integer programming formulation and Benders decomposition algorithm to solve efficiently. Efficacy of the proposed algorithm has been verified by extensive numerical studies and sensitivity analysis.

The fast spread of computer networks and broadband Internet access, and also the development of different operating systems, makes possible to use different virtualization techniques and virtual machines. The release and spread of virtualization platforms makes possible the development of cost-effective information systems that can provide in addition dynamic resource management and simplified system administration. In this paper we present a comparative performance analysis of Remote Desktop Virtualization based on Hyper-V versus Remote Desktop Services. We introduce system architecture for the two tested scenario and test environment including detailed hardware description. The main conclusions of the paper are that despite the higher acquisition and maintenance costs, the Remote Desktop Services outperforms the Hyper-V based Remote Desktop Virtualization in memory, CPU and also storage management.

Patient privacy has recently become the most important issue in the World Health Organization (WHO) and the United States and Europe. However, inter-hospital medical information is currently shared using paper-based operations, and this is an important research issue for the complete and immediate exchange of electronic medical records to avoid duplicate prescriptions or procedures. An electronic medical record (EMR) is a computerized medical record created by a care-giving organization, such as a hospital and doctor's surgery. Using electronic medical records can improve patient's privacy and health care efficiency. Although there are many advantages to electronic medical records, the problem of exchanging and sharing medical images remains to be solved. The motivation of this paper is to attempt to resolve the problems of storing and sharing electronic medical records and medical images between different hospitals. Cloud Computing is enabled by the existing parallel and distributed technology, which provides computing, storage and software services to users. Specifically, this study develops a Medical Image File Accessing System (MIFAS) based on HDFS of Hadoop in cloud. The proposed system can improve medical imaging storage, transmission stability, and reliability while providing an easy-to-operate management interface. This paper focuses on the cloud storage virtualization technology to achieve high-availability services. We have designed and implemented a medical imaging system with a distributed file system. The experimental results show that the high reliability data storage clustering and fault tolerance capabilities can be achieved.

We describe ProDesk, an ubiquitous, projection-based touch surface system that extends the screen space of today's desktop computer workplaces to the whole surface of an ordinary office desk, along with highly accurate multi-touch interaction. The objective of this system is to offer users more flexibility on tasks in which lots of complex information have to be handled. We propose a novel user interface concept that extends normal WIMP functionality and a software architecture that implements this UI concept. We present evaluation results of the system in technical benchmarks and a user study.

It also demonstrates a proof of concept RADIUS appliance and the web-based management interface as well as examples of API integration with a number of products.

This paper presents a safety assessment model with regard to electromagnetic compatibility (EMC) fault suitable for estimating the EMC failure probability (EMC FP) of the complex system facing uncertain electromagnetic environment. First, the model is successfully applied to decompose the complex system into different independent subsystem and equipment. Then the practical EMI scenario is modeled as different typical EMC problem, such as the Plane Wave Coupling and Crosstalk respectively. After that the fault tree analysis (FTA) is proposed to use in combination with electromagnetic topology (EMT) calculating the EMC FP of the system. A focus is put on the practical case of the Desktop Management Interface (DMI) system. In this context, a system-level EMC safety assessment model has been applied to solve EMC FP by uncertainty analysis in high speed railways with the complex electromagnetic environment.

The economies of scale afforded by cloud computing has been a driving force behind the rapid development and deployment of new cloud-based network applications and services. With the massive growth of IoT devices, we expect a sharp rise in the volume of traffic seen going to and coming from cloud datacenters, which will continue to grow over the next several years. Network Function Virtualization (NFV) is a recent concept which promises to grant network operators the required flexibility to quickly develop and provision new network functions and services in the cloud. As NFV is agnostic to the computing resource, we foresee scenarios where unconventional resources such as FPGAs and GPUs will be of benefit. To this end, we present an architecture based on Software-Defined Infrastructure (SDI) which offers an abstracted control and management interface over virtualized heterogeneous resources in the cloud. Through a unified set of APIs, this architecture enables both application developers and network operators to dynamically deploy and manage new services in the cloud alongside the underlying network that interconnects them, all in a fully software-defined manner. We demonstrate and evaluate an implementation of our NFV-enablement architecture using the SAVI testbed, a multi-tier and SDN-enabled cloud containing virtualized heterogeneous compute resources.

Software Defined Networking (SDN) application development is a novel field that has emerged in the context of SDN. This new networking paradigm is intended to mitigate limitations that appeared in traditional networks, such as vendor dependency, complexity or the lack of agility. It gradually migrated through several types of networks, beginning from campus networks, to data centers, transport networks or even Internet exchange points. The SDN ecosystem is expanding, from the SDN controller perspective and both southbound and northbound, including the development of applications. This paper introduces part of the work that was done for the third Wireless Transport SDN Proof of Concept (PoC). The purpose of the PoC was demonstrating the utility of a common information model that would represent a wireless transport device, to be used for its management and configuration in the context of SDN. A simulator consisting of a NETCONF server implementation, that would emulate the management interface of a network element but only return default values for its corresponding YANG attributes (Default Values Mediator — DVM) was realized using the OpenYuma software framework. This eased the development and testing of SDN applications that were proposed and implemented for the use cases of the PoC.

The ongoing integration of various devices and services into nowadays buildings as part of networked building automation systems (BAS) demands for flexible and dynamically adaptable system architectures as they are supported by service orientation, which, moreover, can provide suitable abstractions when integrating new technologies and systems arising for example from the Internet of Things. The increasing complexity of such service systems, however, is accompanied by increasing dependability requirements. Therefore a comprehensive and automated technical management system including service lifecycle management, dynamic (re-)configuration, distributed (re-)deployment, self-repair etc. has to be accomplished. Furthermore the management tasks and the required abstraction of the managed system should span a defined state space in order to enable formal verification of system characteristics like dependability. This work reports on a technical management system utilizing general and system-specific event-condition-action-rules (ECA rules) to enable the dependable operation of BAS. The management tree does not only serve as homogeneous management interface to the BAS, but spans in conjunction with the ECA rules the desired state space.

The remote desktop environment (Virtual Desktop Infrastructure) is attracting interest as a way to strengthen security and support mobile access or telework. To realize the remote desktop environments, a remote desktop protocol is required to transfer information via a network about the user’s operations made on the keyboard and mouse on a terminal to the remote server. The growing popularity of remote desktop environments makes it important to determine the factors that govern the user’s perceived operability with a remote desktop protocol. It is also necessary important to find out the conditions for a wide-area live migration of virtual machines, to use resources efficiently in the remote desktop environments. This paper examines the impact of network quality deterioration (long network delay, high packet loss, small downlink bandwidth) on a user’s perceived operability in remote desktop environments, assuming RDP, PCoIP and ICA as remote desktop protocol. Next, this paper studies the impact of network quality on the performance of a live-migration of virtual machines in remote desktop environments.

Traditional web-based e-learning system suffers from unstable workloads and security risks of incorporating external executable objects to servers. This paper addresses these issues with emerging technologies, as desktop grid and cloud computing. Learning users are motivated to be volunteers by hosting the virtual machines equipped with e-learning desktop grid applications. We develop components to integrate the e-learning system and desktop grid into the circumstance in which each user serves not only a task producer, but also a volunteer that solves tasks. In order to enhance the responsiveness between the passive desktop grid server and e-learning system, we have also developed asynchronous processes to enable the server and volunteer workers to cooperate in a tightly coupled manner. The system achieves the scalability by maintaining the ratio between the number of volunteers and the number of online users beyond certain threshold.

In this paper, the current problems and demands of campus information system was analyzed and the desktop virtualization solutions were probed. Thus, under the cloud system structure, the user can simply login by the client in desktop systems of data center, as well as traditional computer operating. As a result, the flexibility and security in application of resources are enhanced. More over, schools can avoid the repeated investment and reduce the pressure on hardware and software maintenance, and improve the working efficiency.

Desktop grid computing is the computing paradigm that can execute large-scale computing jobs using the desktop resources with heterogeneity and volatility. However, such the computing environment can not guarantee the stability and reliability of task execution because the desktop resources with different performance can freely participate and leave in task execution. Therefore, in this paper, we design resource grouping scheme using k-means clustering algorithm with an aim to provide desktop grid computing with the stability and reliability of task execution. Moreover, we conduct resource grouping using the execution log data of actual desktop grid systems and present application methods of desktop resource groups to fault-tolerance.
