In the future intelligent transport systems (ITS) the reliability and precision of the cooperative and autonomous vehicles are of the utmost importance. For such systems vehicle-to-vehicle and vehicle-to-infrastructure (V2X) communications is safety-critical component of ITS. Many mobility and convenience applications of ITS require the V2X bidirectional communications mode. This paper focuses on...
General reliability and availability analysis methods that can be applied to structures, systems, and components (SSCs) in nuclear power generating stations and other nuclear facilities are contained in this guide.
Emergency protection of objects in the process of testing and functioning should respond to a wide range of abnormal situations: malfunctions, which can be eliminated during testing; emergency situations that can be eliminated in the operational mode, or require the shutdown of the process and the elimination of the consequences of the accident; catastrophic situations that require an a priori reaction...
Safety Instrumented Systems (SIS) act as important safety barriers in industrial systems for preventing hazardous accidents. It is therefore significant to study the reliability issues of SIS. As a matter of fact, SIS have common behaviors such as periodic test policies to discover dangerous undetected failures. Modeling patterns capitalize the experience from modeling SIS. By reusing modeling patterns,...
This paper proposes a reliable MAC protocol for a fully distributed Vehicular Ad-Hoc Network (VANET) using the slot states sharing scheme. Recently, technology for reliably transmitting safety messages in VANET has become an issue. With VANET (operating on the IEEE 802.11p standard), as the number of vehicles increases on the highway, the network traffic also increases. It causes more frequent packet...
There are two broad safety related message categories in vehicular networks: emergency and periodic messages that should share the scarce wireless resource simultaneously. Emergency messages deliver time-critical information with guaranteed reliability, e.g., road-safety information, whereas periodic ones convey normal status update information, e.g., vehicular positions, that is less time- and loss-critical...
A functional safety solution based on multi-purpose built-in self-test and repair infrastructure for automotive SoCs is presented. This solution allows building a hierarchical network and managing it in multiple in-field test and repair modes.
A Reliable power transmission is one of the asset management objective of PLN Trans-JBTB as a Power Transmission Utility. This objective is measured by frequency and duration outages of transmission line and transformer (TLOD, TROD, TLOF, and TROF) that occur every year. In order to improve reliability, fault history data in 2014–2017 is evaluated using FMECA and risk matrix to obtain a failure mode...
In the paper, principles of constructing systems of information support of human-operators (IOSS) of power units of nuclear power plants (NPP) and their place within the system of upper unit-level of automated process control systems (APCS) of NPP. The purpose of implementation of the NPP IOSS is preventing or decreasing the frequency and heaviness of operator errors appearing under transients and...
This paper proposes an in-vehicle power line communication (PLC) system which provides an in-vehicle communication for the video and vehicle messages transmission as a reliable alternative networking medium. The proposed in-vehicle PLC system adopts an existing in-vehicle 12-V battery power system, which means we don't need an external DC power supply for in-vehicle communication equipment to achieve...
The rapidly growing software content within the vehicles continue to make automotive systems more intelligent through the addition of software enabled electronics. A plethora of change in the automotive industry is largely driven by the embedded software technology. The Advanced Driver Assistance Systems are one of such innovations of technology which are gaining widespread momentum in today's ever...
Dependability of cyber-physical systems rests crucially on the fidelity of formal models to their real-world physical subject matter; yet little explicitly focused research has been devoted to this concern. This talk sketches the concern and commends it as a focus for future research in the RE community.
This paper reveals that the standard test procedures for the qualification and verification of traction battery systems are not sufficient in certain cases. In fact, realistic and application-oriented tests on the interaction among the complex battery subsystems are inevitable. To achieve these objectives, a high-performance test bench with the unique selling features of a high voltage/- and current...
With the envisioned era of Internet of Vehicles (IoVs), all aspects of Intelligent Transportation Systems (ITS) will be connected to improve transport safety, relieve traffic congestion, reduce air pollution, enhance the comfort of transportation and significantly reduce road accidents. In IoVs, regular exchange of current position, direction, velocity, etc., enables mobile vehicles to predict an...
The Internet of Things (IoT) is captivating the society because of its potential to rapidly transform businesses and people's lives. It is widely believed that IoT will also transform the industrial automation business in terms of improved productivity, less cost, flexibility, and increased revenues. Hence, there are some challenges that needs to be addressed when IoT is introduced to the industrial...
The use of wireless technologies within factories demands a comprehensive understanding of the problems and potential solutions associated with the rigors of the manufacturing environment. A clearly defined problem space would significantly ease the selection and deployment of appropriate wireless solutions to connected factory systems. A mapping of potential technologies to classes of use cases within...
Every facility, regardless of size, has process loads which are considered critical. However, what does the term “critical” mean? A process engineer's ideas of a critical load may differ from those of an electrical engineer, an HSE engineer, or plant engineer. This paper defines critical loads and discusses a methodology to evaluate if a load should be considered critical. The methodology considers...
Dependability models are focused only on the basic stuck-at faults. In previous work a method has been shown on how to calculate dependability prediction using Markov chain models. This method has been described using the TMR architecture. In this paper a similar method for calculating the dependability parameter lambda (i.e., the failure rate of the system) is proposed. Focus is given on the dependability...
Network-based deployments within the Internet of Things increasingly rely on the cloud-controlled federation of individual networks to configure, authorize, and manage devices across network borders. While this approach allows the convenient and reliable interconnection of networks, it raises severe security and safety concerns. These concerns range from a curious cloud provider accessing confidential...
Intelligent Transportation Systems (ITSs) are built considering numerous legal regulations, organisational conditions, and user needs. For this reason, they cannot be sold as plug & play products and their implementation requires a clear definition of functional and technical requirements. The primary objective of ITSs is to improve the efficiency and safety of road traffic. In fact, nowadays,...
