Today's industry increasingly requires flexibility and adaptability in the development of automation control software, especially for automated production systems (aPS) including an automated material flow system (aMFS). To meet these demands, the development of the automation control software and the modification during the operation of the aMFS has to become as easy as possible without taking a...
When designing dependable cyber-physical systems, software architects must plan for defects and environmentally caused failures. Determining the right degree of redundancy is a complex task which requires balancing failure potential reduction, additional coordination effort, increased costs, weight, and power consumption. An efficient fail-operational design requires software-based measures increasing...
As technology improves in size and the number of smart devices increases, security in personal devices undoubtedly becomes an important aspect of today's life. However, the complexity in hardware and software systems expose vulnerabilities in security. Vulnerabilities may exist in many layers of systems and would require a specific inputs or events to trigger it. Discovery of vulnerabilities require...
Today's research projects propose a modular manufacturing environment for production sites, which adapt itself autonomously and makes manufacturing decisions without human interaction. Therefore, it is necessary that the next generations of production lines, especially the intralogistics transportation systems, are designed more adaptable and flexible. The object in this paper is a cyber-physical...
Enabling interfaces to declare (instance) method implementations, Java 8 default methods can be used as a substitute for the ubiquitous skeletal implementation software design pattern. Performing this transformation on legacy software manually, though, may be non-trivial. The refactoring requires analyzing complex type hierarchies, resolving multiple implementation inheritance issues, reconciling...
This report shows that the architecture of Big Banks' Management Control Systems can be presented as a two or three-tier structure without separating the functional components to the front and back office. The report also examines the key legislative and regulatory documents that define the specific requirements for the Big Banks' Management Control Systems' Software. Functional components' classification...
This study describes the roles of architects in scaling agile frameworks with the help of a structured literature review. We aim to provide a primary analysis of 20 identified scaling agile frameworks. Subsequently, we thoroughly describe three popular scaling agile frameworks: Scaled Agile Framework, Large Scale Scrum, and Disciplined Agile 2.0. After specifying the main concepts of scaling agile...
In order to develop the bottom driver software more rapidly and efficiently which are used in automotive battery management system and to get rid of high dependence on the hardware and low reusability of the drivers in automobile controller, this paper puts forward a kind of driver design method based on automotive open system architecture (AUTOSAR). Simulation modeling module has been made with the...
In addition to in-house applications, networked enterprises are increasingly using data and services from various external sources. Conversion of data to useful information and IT alignment with business goals are big challenges faced by these enterprises. Integration platforms (IPs) aid enterprises in solving such challenges. However, the large number of commercial and academic IPs currently available...
The use of an Application Lifecycle Management (ALM) system to promote cross-discipline data capture, tracking and traceability has shown to provide a dramatic improvement during airworthiness audits of software-centric avionics systems by reducing both the time to locate relevant information and rework associated with errors in captured data and their traceability. When configured correctly, an ALM...
The development of a network centered life has increased overall data rates in core networks. Thus, data centers face the challenge to provide always more services at higher data rates while reacting quickly to complex failures and more powerful attacks thanks to efficient network forensics. Moreover, Software-Defined Networking (SDN) becomes a standard which offers agility but also requires forensic...
Web service is a popular solution to integrate components when building a software system, or to allow communication between a system and third-party users, providing a flexible and reusable mechanism to access its functionalities. Various web service based systems are prevailing in health service provision. We propose a framework of construction, searching and protection of typed health resources...
Recently, a micro-service architecture has been adopted to an edge device in smart factory due to its maintainability and scalability. In the architecture, all services are generally implemented as Docker containers and deployed by Docker APIs which might be harsh to a factory operator. In this paper, we propose an easy-to-use web-based service deployment method for containerized service to in-factory...
Remote Laboratories are used in educational settings as tools to give students access to experiments that are not physically available to them at their institutions. During implementation, problems such as: bandwidth, security or limitations in terms of the usability, have been identified. This paper proposes an approach that integrates, what we call, a Smart Adaptive Remote Laboratory (SARL) with...
Conventional cyber defenses require continual maintenance: virus, firmware, and software updates; costly functional impact tests; and dedicated staff within a security operations center. The conventional defenses require access to external sources for the latest updates. The whitelisted system, however, is ideally a system that can sustain itself freed from external inputs. Cyber-Physical Systems...
Real-time lossless compression can reduce the burden of big data transmission and storage. Hardware compression is faster and more energy saving when compared with software. This paper proposes a novel LZO hardware architecture and various acceleration methods, integrates the compressor module and other IP modules. Finally, test and demonstration are provided on the DE2 development board. The results...
This work presents the major characteristics and lessons learned by the development and prototype implementation of an event-oriented and cloud-based SCADA system that is constructed using a microservice architecture. The microservices are then utilized to propose an approach for implementing product-driven production systems under the RAMI4.0 specification.
The purpose of the following study is present the MOOC Information System Generic Architecture as a result of the analysis of quality characteristics found in the literature concerning of MOOC, and the application of the Discovering Hybrid ARchitectures by Modelling Actors (DHARMA) method based on the use of i∗. Generic Architecture refers to the identification of MOOC system actors, the services...
Software Defined Networks (SDN) has been attracting various researchers from both academia and industry to enhance the current ICT stakes and networking paradigm. The beauty of SDN is the division of Control and Data planes and make it easy for the engineers to modify the networking protocols without visiting onsite devices. Similarly, Smart Cities concept has been coined recently, where a plethora...
Virtual Content Delivery Network (vCDN) orchestration is necessary to optimize the use of resources and improve the performance of the overall SDN/NFV-based CDN function in terms of network operator cost reduction and high streaming quality. It requires intelligent and enticed joint SDN/NFV orchestration algorithm due to the evident huge amount of traffic to be delivered to end customers of the network...
