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...
Formal verification has become very useful and popular in last decade in area of embedded systems design and in analysis of critical systems. It can reveal common errors like deadlocks, starvation, check system invariants, but also verify more complex properties defined by LTL formulas whose writing may be very error prone for non expert users. To reduce the time-to-market for embedded systems and...
This paper discusses the open issues in incorporating trust techniques in the NFV environment specified by the ETSI NFV Industry Specification Group, and analyses the available technologies to fill this gap. ETSI is developing security and trust specifications within its NFV-SEC working group, with the aim of establishing and assessing trust of both the hardware platform and the virtualised infrastructure...
This work presents a low-area scalable architecture for the Depth Modelling Mode 1 (DMM-1) encoder of the 3D High Efficiency Video Coding (3D-HEVC) standard, removing the refinement stage. This simplification causes a small BD-rate increase (0.09%) but a significant reduction in memory usage of 30%. The scalable architecture can support different block sizes. Synthesis results for ST 65 nm Standard...
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...
The methodological aspects of building standardized profiles describing the development of a security system that is an integral part of a distributed information system are considered. Functional standardization instruments and the theory of open systems are used.
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...
Energy efficiency has become a primary concern in the design of multimedia digital systems, particularly when targeting mobile devices. Approximate computing is a highly promising approach to address this challenge. This paper presents an architectural exploration in a variable block size motion estimation (VBSME) architecture using imprecise Lower-Part-OR Adders (LOA). These adders were applied to...
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,...

The generation of pseudorandom number sequences can be achieved in a variety of ways, with the most secure methods generally requiring substantial processing to generate. Other pseudorandom number generation (PRNG) methods accept a compromise between processing power and security by mixing two independent, but less secure, PRNG outputs with each other. This paper presents a generalized mixing method...
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,...
An improved real-time method for smoke detection based on motion and color analysis is presented. Smoke detection in video surveillance is very important for early fire detection. In general, it is assumed that smoke is a low frequency signal, which may smooth the background. However, these conditions can be met by some pure-color objects, and smoke also produces high frequency signal on the edges...
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...
Approximate computing addresses many of the identified challenges for exascale computing, leading to performance improvements that may include changes in fidelity of calculation. In this paper, we examine approximate approaches for a range of DOE-relevant computational problems run on a variety of architectures as a proxy for the wider set of exascaleclass applications.We show anticipated improvements...
The determining problem of several fracton mixture srtucture of materials grinding in the gas jet mill is considered. The problem is solved by comparing the standard deviation of the standart power spectral density of acoustics signals of individual fractions and of the mixture ones.
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.
Accelerators are specialized hardware designs that generally guarantee two to three orders of magnitude higher energy efficiency than general-purpose processor cores for their target computational kernels. To cope with the complexity of integrating many accelerators into heterogeneous systems, we have proposed Embedded Scalable Platforms (ESP) that combines a flexible architecture with a companion...
