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...
Urban electrical distribution networks are mostly comprised of Medium Voltage (MV) ring distribution feeders to improve reliability. Transformers connected to MV feeders transfer power from MV network to Low Voltage (LV) distribution networks. In underground LV distribution networks, feeder pillars are used to branch out LV feeders emerging from distribution transformers. Currently, the existing distribution...
The article deals with the method for the assessment of the fiber-optic communication line reliability taking into account the effect of the optical fiber tension, the temperature influence and the built-in diagnostic equipment errors of the first kind. The reliability is assessed using the theory of Markov chains and probabilistic mathematical modeling. The reliability is assessed in terms of the...
With the rapid advances in IoT technologies, the role of IoT gateways becomes even more important. Therefore, improving the reliability, availability and serviceability (RAS) of IoT gateways is crucial. Nowadays, Linux is widely adopted for core enterprise systems not only because it is a free operating system but also because it offers advantages in regards to operational stability. With many Linux...
Digital lifestyle with always-on connection to internet as well as the emergence of Internet of Things (IoT) throughout the world calls for reliable, concurrently maintainable data center and telecommunications systems. Thus, this need had pushed the limit of electrical and mechanical system, in particular power and cooling systems to provide reliable, economical and maintainable services. This requirements...
In this paper, Spread Spectrum Time Domain Reflectometry (SSTDR) has been implemented for the first time across the gate and the source of a power metal oxide semiconductor field effect transistor (MOSFET) to perform the online degradation monitoring of switching devices as well as the overall converter. To accomplish this, the SSTDR test signal is superimposed with the pulse width modulated (PWM)...
Research in the area of internet-of-things, cyberphysical-systems, and smart health often employ sensor systems at residences for continuous monitoring. Such research-oriented residential monitoring systems (RRMSs) usually face two major challenges, long-term reliable operation management and validation of system functionality with minimal human effort. Targeting these two challenges, this paper describes...
Along with our country the implementation of the strategy of developing the new energy, solar energy is a kind of ideal clean energy future energy, with the power grid operation requirements of photovoltaic power generation system is increasing day by day, for the needs of the operation and control, is necessary for photovoltaic system monitoring, photovoltaic power plant key components of condition...
We introduce a methodology for efficient monitoring of processes running on hosts in a corporate network. The methodology is based on collecting streams of system calls produced by all or selected processes on the hosts, and sending them over the network to a monitoring server, where machine learning algorithms are used to identify changes in process behavior due to malicious activity, hardware failures,...
Research objects were designed in data-intensive science under the premises of interoperability and machine-readability to describe scientific processes and findings including all the resources that were used in the research endeavour. In this poster we present our work with Earth Science communities, that have embraced the research object model for long-term preservation and reuse of knowledge, to...
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...
With the requirement of real-time and reliability on monitoring power transmission lines, this paper proposes a cooperative communication protocol with network coding in long-chain wireless sensor networks (WSN). The protocol makes full use of channel broadcast characteristics and cooperative communication. It applies the classical butterfly structure of network coding among the successive three hops...
Some approaches and techniques that allow conducting of complex physiological research using closed-architecture measurement systems of different manufacturers are discussed. The experience in developing a system with flexible configuration and in solving arising problems by virtue of integration of equipment using an external synchronizing device, is described. Parallels are drawn with the modern...
The trends of transistor size and system complexity scaling continue. As a result, soft errors in the system, including the processor core, are predicted to become one of the major reliability challenges. A fraction of soft errors at the device level could become an unmasked error visible to the user. Unmasked soft errors may manifest as a detectable error, which could be recoverable (DRE) or unrecoverable...
The questions connected with the use of the modern element base in the development of some types of monitoring and monitoring systems for large-scale objects are considered.
The article considers the problem of complex estimation of the product state, associated with the need to help decision-makers in managing the life cycle of space facilities. A system analysis of the subject area was conducted, which showed the presence of limitations in the existing information system of the technical state and reliability of space facilities. The article presents a new intellectual...
The power grid is a complex, interconnected system that requires the coordination of multiple entities to ensure the reliability of the system. System operators must be aware of the impacts of various natural and man-made contingencies through telemetry from their control systems, and they must also be aware of the integrity and availability of the cyber assets on their systems. A team of researchers...
This paper presents a in situ on-chip micro tensile fracture strength tester, which is based on a thermal actuated test platform. In this test platform, tensile fracture strength could be extracted and process could be evaluated, there are two samples with same layout but fabricated under different process conditions were evaluated through this test platform and the results showed that this test platform...
Due to technology scaling, which means smaller transistor, lower voltage and more aggressive clock frequency, VLSI devices are becoming more susceptible against soft errors. Especially for those devices deployed in safety- and mission-critical applications, dependability and reliability are becoming increasingly important constraints during the development of system on/around them. Other phenomena...
In recent years, with the rapid development of China's high-speed railway, high-speed rail EMU production is also increasing, but the existing high-speed rail EMU brake test system requires a lot of manual operation, recording, workload, braking signal and data, vehicle status confirmation can not be centralized managed, archiving. The structure is complex with high maintenance requirements and the...
