This paper presents the latest functional safety innovations at the power management level of a System Basis Chip (SBC), from the development phase to system design, underscoring the link to reliability and how to enable hardware that is safety ready. The presentation will also demonstrate how using architecture developed for Automotive Safety Integrity Level (ASIL) can help improve the functional...
Nowadays, the nuclear island and conventional island make use of sea water to cooling in most of nuclear power plant, in order to maintain the heat dynamic balance of nuclear power plant, and to protect the safety of nuclear power plants. As a result, the safety of the cold source system for nuclear power plant production and operation has a very important role. In this paper, by analyzing the threat...
Combining actual demands for ultra-high voltage (UHV) power grid of our country electricity production, power collection, electricity transmission and distribution, functions, adequacy and reliability of different UHV power grid projection are discussed in this paper. They were discussed that differences in function and reliability of different UHV power grid structure, and the development necessity,...
Probabilistic safety assessment is one of the standardized ways of assessing safety of nuclear power plants. The objective of the method is to present an extension of the fault tree in order to reduce the size of the shutdown probabilistic safety assessment model. The shutdown probabilistic safety assessment method is developed. The modelling for all plant operating states include consideration of...
Current public safety (PS) networks support mission critical voice communication, but are limited to narrowband data. As long term evolution (LTE) is the most widely deployed broadband communication technology so far, efforts are being made to develop LTE-based mission critical PS communication systems. In this paper, we propose delayed-response-based device discovery to support the application of...
The article deals with the issue of quality and competitiveness of “electric drive — stop valves” systems. The main reasons for the decline of systems' competitiveness are given. The stiffness of the mechanical part of the system is suggested as a new control parameter. When designing it allows to increase competitive advantage of national systems provided that general requirements of NPP safety are...
A high-temperature gas-cooled reactor-pebble bed module (HTR-PM), as a demonstration nuclear power plant (NPP), is now under construction in the Shandong province of China. The reactor protection system (RPS) in an HTR-PM is a safety-related system and is mainly in charge of monitoring safety-related parameters according to the reactor protection requirements. Thus, an RPS is very important to operations...
VANET (Vehicular ad hoc network) is a network which mainly consists of mobile nodes which are categorized by high speed, dynamically changing topology, lack of any central authority, relationship between nodes are often short lived. It is a network which mainly focus on providing applications which save human lives and provide comfort to drivers during driving. So, Communication which are of two types,...
In this study, the implementation of monitoring system is made, aimed for home surveillance. The sensor of the system is camera. The camera will capture image of the room and will evaluate whether an intruder is detected or not, by subtracting the image with the background frame. When the intruder is detected, the system will automatically activate the alarm to alert the home occupant. In the same...
10kV cross-linked polyethylene (XLPE) cables are widely used in power system because of its advantages of small external influence factors and high reliability and safety. However, cable accessories are weak links of the cable lines. Considering the hot and humid environment in Guangzhou areas, the applicability of cold and hot shrinkable cable accessories is questionable. This paper has carried out...
In cellular networks, the introduction of device-to device (D2D) technology could promote cell coverage and expand user experience. In this paper, we consider the scenario of relay assisted D2D communications, and developed an adaptive architecture for D2D communications to be used in emergency conditions. Such events are difficult to predict. Therefore, their situations are accompanied by uncertainty...
Driving with shared control systems has been shown to be efficient in reducing collisions during a lane change. However, the ability of the current shared control systems is limited and their absolute reliability is not assured. The goal of this study is to determine how changes in system performance affect human-machine cooperation and safety. An experiment using a driving simulator was designed...
The purpose of this paper is to illustrate the Internet of Everything based integrated security system designed for World War One commemorative Museum of Fogliano Redipuglia in Italy, capable of ensuring visitors security, cultural heritage préservâtion/protection and great usability for visitors, with particular reference to visitors with disabilities. Genetic Algorithms (GAs) have been used to design...
Infrastructure Asset Management was first adopted in 1980s for challenges faced by the utilities, road and rail transport systems, mining, process and manufacturing industries in asset life cycle value optimization. International standards ISO 55000 and PAS 55 were subsequently developed to provide a basis for a structured methodology in the development of Asset Management System. This methodology...
Air safety authorities are forced to develop regulations for UAS due to incidents disturbing public safety and demands from UAS operators. Despite numerous studies from the FAA and EASA, none of them decided on a regulation for UASs. The reliability of the flight is considered to be one of the main obstacles for UAVs integration. This is not an easy topic considering the unknowns of the systems, environment...
As demands increase to use unmanned aircraft systems (UAS) for a broad spectrum of commercial applications, regulatory authorities are examining how to safely integrate them without loss of safety or major disruption to existing airspace operations. This work addresses the development of the Safeguard system as an assured safety net technology for UAS. The Safeguard system monitors and enforces conformance...
This paper presents a summary and analysis deployment of a secure Intelligent Electronic Device (IED) management system at two different utilities in North America. Each of these utilities began their investigation into technologies and methodologies for securing their system for North America Reliability Corporation (NERC) Critical Infrastructure Protection (CIP) standards. This report is intended...
Security for women has become a major issue in most of the countries. Survey results shows that every year around 25000 crime against women were booked across India. From the last ten years, the statistics among women abusement, sexual harassment have been steadily increasing. It has become mandatory to come up with a solution to protect the women from being a victim and to reduce the attacks. The...
In the United States, medium-voltage power distribution typically uses withdrawable circuit breaker switchgear. Withdrawable breakers allow for regular maintenance and provide an easily visible confirmation of circuit isolation but at a cost — having removable parts and the act of inserting and withdrawing breakers could result in the possibility of causing arc flash incidents. Modern fixed circuit...
The fuse is a very important component for the protection of power electronic devices. There are several parameters for choosing. Inrush energy is considered as an important parameter. This paper presents the calculation of the fuse melting point by inrush energy and determination of the eligibility. The testing set has been designed as case study.
