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...
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...
The IEEE 1516-2010 — Standard for Modeling and Simulation High Level Architecture (HLA) range of standards are widely used for distributed simulation, interoperability, reusability and the modeling of large-scale systems in many application domains. Although it provides several advantages, the development of distributed simulations based on the HLA standards remains a challenging task that requires...
Given the recent difficulty in continuing the classic CMOS manufacturing density and power scaling curves, also known as Moore's Law and Dennard Scaling, respectively, we find that modern complex system architectures are increasingly relying upon accelerators in order to optimize the placement of specific computational workloads. In addition, large-scale computing infrastructures utilized in HPC,...
The work is focused on intellectualization of the development process of integrated expert systems basing on the the problem-oriented methodology and AT-TECHNOLOGY workbench. Basic intelligent software environment components like intelligent planner, reusable components, standard design procedures are described. Development process with use of intelligent technology is reviewed. An example development...
In this work, we present a modular software subsystem that exposes a set of APIs for supporting the automation of a set of design choices in the synthesis of a hardware accelerator by a proprietary FPGA toolchain. We model the subsystem around Vivado, Xilinx's proprietary FPGA toolchain, in order to provide a finer grained control on the toolchain's features with respect to the standard .tcl interface...
In this work, we present a proposal for a reference architecture for the modeling and execution of business processes. We define business processes following the subject-oriented business process management (S-BPM) methodology, which recently has been amalgamated in a Web Ontology Language (OWL) definition. Consequently, all created process definitions are serialized as OWL files. The S-BPM approach...
The vehicles typically have a lifetime of several years, possibly even longer than 10 years, over which communication technology will almost certainly evolve dramatically. The challenge of automotive communication platform is to ensure that a radio communication component remains relevant over the entire lifetime of a vehicle. A highly efficient software reconfiguration solution is introduced in this...
Architecture-Driven Modernization (ADM) intends to standardize software reengineering by relying on a family of standard metamodels. Knowledge-Discovery Metamodel (KDM) is the main ADM ISO metamodel aiming at representing all aspects of existing legacy systems. One of the internal KDM metamodels is called Structure, responsible for representing architectural abstractions (Layers, Components and Subsystems)...
Softwarization is a systemic trend which appears under several paradigms impacting networks, services and terminals evolution. Even the Internet of Things (IoT) scenario is going to be affected by this revolution. The efforts that are being made to provide IoT objects with embedded logic reconfiguration capabilities and the architectures that are being defined to support standard Machine-2-Machine...
Service Function Chaining (SFC) serves the traffic of a specific service along an ordered set of Service Functions (SFs). SFC uses Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies to reach the deployment and removal of SFC in an appropriate time with minimal costs. However, during the life time of deployed SFCs, the SFs are exposed to the risk of overloading,...
Programmable Logic Controllers (PLCs) are specialized computing systems for the control and monitoring of distributed industrial devices. Aiming for a highly connected industrial Internet-of-Things (IoT) ecosystem, PLCopen OPC Unified Architecture (UA) specification has been released. This paper presents the implementation and evaluation of a PLCopen OPC-UA software component for industrial control...
In this paper, a reconfigurable component based on the new platform is designed for the intercommunication between different communication devices and the difficulty of software and hardware upgrade with the purpose of improving the portability and sharing of components. According to the development process of reconfigurable components and the key technology of reconfigurable components in GNU Radio...
This paper presents a System-on-Chip approach (SoC), exploiting the availability and capacity of SRAM-based FPGA technology to design and implement an on-board computer system (OBC) for use in low earth orbit (LEO) nano-satellite. This work is part of a University project that aims to develop the first Moroccan university nano-satellite based on the “CubeSat” standard. As such, the proposed OBC is...
This paper is an exploratory study on architects' attitudes towards risk and its influences on the architectural decision-making process. A classification of architects' attitude to risk-taking has been developed on the basis of Fowler's Technical Debt Quadrants. The core proposition of the paper is that the well-established concept of 'risk appetite' can be equally well applied to characterise and...
Rockwell Collins, in Cedar Rapids, Iowa, is using a product line approach for a family of radios they produce for military and international markets, with an agile systems engineering process tailored individually for synchronized software, firmware, and hardware development. This mixed-discipline engineering group encompasses some 350 employees working on multiple projects simultaneously for multiple...
In vehicular communication protocol stacks, received messages may not always be decoded successfully due to the complexity of the decoding functions, the uncertainty of the communication load and the limited computation resources. Even worse, an improper implementation of the protocol stack may cause an unfair data age distribution among all the communicating vehicles (the receiving bias problem)...
Agile methods have gained wide acceptance over the past several years, to the point that they are now a standard management and execution approach for small-scale software development projects. While conventional Agile methods are not generally applicable to large multi-year and mission-critical systems, Agile hybrids are now being developed (such as SAFe) to exploit the productivity improvements...
Software defined networking (SDN) is a new networking paradigm that in recent years has revolutionized network architectures. At its core, SDN separates the data plane, which provides data forwarding functionalities, and the control plane, which implements the network control logic. The separation of these two components provides a virtually centralized point of control in the network, and at the...
Over the previous years, many service-oriented (SO) solutions have been proposed by European research projects for the technological advancement of industrial systems. These projects typically include a software reference architecture (RA) based on the concepts of service-oriented architectures (SOA) and, often-times, an accompanying technology stack to guarantee system-wide interoperability. In this...
