optimization of maintenance resources to maximize the system availability is a major concern in different manufacturing systems. therefore, a lot of effort is put to construct optimization models to reach the maximum availability level and to reduce the costs of lack of availability. however, despite these efforts, data uncertainty in the real world problems was neglected in proposed models whi...

Modern power-network communications are based on the IEC 61850 series standards. In this paper, we investigate real-time performance and vulnerabilities attack scenarios at sensor level communication networks more precisely Sampled Measured Value protocol. The approach jointly evaluates protocol, network topology impact electrical protection functions. We test practical feasibility of attacks a...

Abstract As a rocket engine for thrust vector control system of high reliability and redundancy, precision, the requirements lightweight, servo test can quickly certain level fast data processing location, transient, frequency characteristic indexes, motor using GLINK as bus. Moreover, first is an all-in-one machine with four drives controls, so required to have ability actuators simultaneously...

Abstract PUF (Physical unclonable function) is a new hardware security primitive, and the research on PUFs one of emerging focuses. For PUF-based mutual authentication protocols, method to abstract properties by using logic events proposed, application aspects are extended protocols based security. With interaction protocol formally described events, basic sequences constructed strong property ...

Hardware faults on the regular 2-D computing array of a typical deep learning accelerator (DLA) can lead to dramatic prediction accuracy loss. Prior redundancy design approaches typically have each homogeneous redundant processing element (PE) mitigate faulty PEs for limited region rather than entire avoid excessive hardware overhead. However, they fail recover when number in any exceeds same r...

The parallelism allowed by FPGAs has attracted attention for knowing applications that need processing power. However, the specific and very technical development language not stimulate its broad use. As an alternative, there are High-level Synthesis Languages (HSL), which allow less complicated FPGA they do tend to take full advantage of technology. Therefore, another alternative was developed...

many of the video processing algorithms cannot be implemented in real time on general computers, due to their computational complexity. for an efficient implementation, a custom hardware that can be reconfigured for the algorithm, is used. in this paper a new acceleration hardware based on fpga elements is proposed. this hardware can be adapted with the processing algorithm through fpga design ...

There are generally considered to be four major types of digital circuit redundancy techniques in use today. They are the Shannon-Moore component redundancy method, the "quadded logic" approach suggested by Tryon,von Neumann's triplication and majority-voting technique, and the basic standby redundancy systems. When viewed in the light of design criteria which are based upon the requirements of...

Mobile communication has a great potential to the users due to fulfilling the dreams of real-time multimedia communication like voice, image, and text. The huge amount of data redundancy in still image should be compressed using exact image compression algorithm (ICA) before transmitting via wireless channel. Thus, an ICA should be adaptive, simple, and cost-effective and suitable for feasible ...
