Traditionally unmanned undersea vehicles (UUVs) have been large, complex and expensive. Development of UUVs has been driven by defense and commercial requirements. This has allowed for extensive research and development budgets and long development cycles. This paper briefly discuses these historic drivers and how this situation has changed. It focuses on a new compact affordable UUV. In 2015, several...
In this work, a method to design STIM for sensor network system is proposed. Hardware selects TMS320F28335 as main controller. A common software implementation method is also presented. Electronic spreadsheet and independent interface configuration is the key research points to realize hot-plug function. After testing, system can be used in electric transmission line leakage current and voltage detection...
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...
Modern systems are becoming ever more complex and, thus, the possibility of failures in their operation is also growing. The complexity makes it practically impossible to make the hardware and software error-free without the special effort invested in the design process. Recently, a design methodology with the objective to avoid unacceptable risk of physical injury or of damage to the health of people,...
This design provides a kind of double CPU communication between solution, using PROTUES software structures, basic simulation circuit, the load KEIL software written in HEX file, USES the RS232 interface standard, simple circuit structure, solve the problem of the complicated parallel communication lines, applies to close range, low rate of communication occasions.
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,...
Due to the growing size of compute clusters, large scale parallel applications increasingly have to deal with hardware malfunctions and other failure scenarios during execution. The overall goal of this research is to get good performance of MapReduce applications despite failures. The paper focuses on evaluation of the performance of two representative Hadoop MapReduce applications, 'WordCount' and...
Household energy consumption is largely inefficient. In recent years, development in residential energy-use optimisation has attracted a great deal of attention. Given that consumers comprise a significant part of total demand, there is an incentive to assist users to manage household demand. This paper provides an introduction to Home Energy Management (HEM). An overview of available Home Energy...
A problem-oriented processor on the basis FPGA for high-precision calculations in floating-point formats (64-, 80-, 128-bit) for solving poorly conditioned systems of linear algebraic equations by the Gauss method was developed.
It is important to allow the test engineer great flexibility when developing a test program. Highly skilled test engineers desire flexibility and different hardware platforms to test a Unit Under Test (UUT). In the past, the engineer was told to use specific test equipment and not provided with the option to program an instrument to their specific test and diagnostic plans. Being stuck in a rut on...
To utilize the proper test techniques that expand our test and diagnosis process we should regularly evaluate and integrate new devices and new techniques. Willingness to embrace change is the major requirement for successful technology integration. Test technology is continuously and rapidly evolving. It is an ongoing process and demands continual research and understanding. Effective integration...
DOD Automatic Test Systems (ATS) guidance addresses the DOD-wide problem of Automatic Test Equipment (ATE) proliferation by establishing a requirement for a standard family of ATE in each Service that is based on non-proprietary open-architecture hardware and software. Policy requirements for ATS management are described in Navy Instructions and Army Regulations and DA PAMs. These guidance publications...
A new turn in information revolution contributed to the formation of a new universal identity of the uniform postindustrial society. We refer to this phenomenon as the concept of a “New axial period”. The system of education, like all cultural institutions, turned out to be not ready for such a breakthrough in creating a new reality that entails certain problems. Among the problems are: pedagogical...
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...
This paper presents the work performed at (removed for blind review) to automate the integration of virtual systems development (VSD) and simulation in its embedded software development process. The approach is based on a combination of metamodels, model transformations and design patterns, the SysML standard and the use of the open source Eclipse framework. The purpose is to derive all the design...
This article introduces the Hardware Robot Operating System (H-ROS), a joint hardware and software infrastructure to create vendor-agnostic reusable and reconfigurable robot hardware components. These robot components dynamically modify and extend the internal representation model of the robot enabling robots to switch on or off components selectively and literally exchange hardware components between...
Inter-vehicle communication (IVC) is a key component enabling the autonomous driving vehicles. Standardization of IVC is advanced but yet improvements are still introduced. Congestion control is one of the sensitive topics. The IVC European standard ITS-G5 addresses the congestion issue enabled by a geo-networking protocol that exploits at networking level the geographic information. Implementation...
This paper presents a versatile implementation of a reconfigurable module for acquisition and synthesis of modulated signals that are specific to the modern communication equipments. The hardware structure of the system is elaborated mainly around the TDA 8702 high speed video digital-to-analog converter and ADC 0820 analog-to-digital converter, both connected in a configuration that is controlled...
