The main task of modern electric networks is the reliability of electricity supply to consumers, as well as in optimizing voltage levels. One of the possible measures to increase reliability is the construction of a rational topology of the electrical network and the use of distributed generation in the form of alternative sources of electricity. Such networks allow you to dynamically adjust the parameters...
Asymmetric Error Reduction Huffman Coding (AERH) is proposed for MLC/3LC NAND flash memory used as SSD cache in the tiered hierarchical storage. AERH compresses data, reduces asymmetric memory cell errors by modulating Vth distribution and thus enhances reliability and endurance of memory cells. AERH decreases data-retention errors by 72.6% and 82.6% of MLC and 3LC NAND flash, respectively. In addition,...
This paper reports on a large-size CPU package for UNIX servers which employs embedded thin film capacitor layers. The substrate of this package has two thin film capacitor layers in the surface of the core layer, which has a capacitance of 25 uF in total. In order to adopt this package substrate, we confirmed the effect of the thin film capacitor layers on the package assembly process. We actually...
With the rapid growth in the mobile industry, Package-on-Package (PoP) technology has been widely adopted for the 3D integration of logic and memory devices within mobile handsets and other portable multimedia products. The PoP solution offers significant advantages, including increased density through stacking logic and memory devices in the same formfactor and a high degree of flexibility for variable...
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...
The challenges of the Internet of Things (IoT) in an urban environment are driven by smart vehicles which need to be able to efficiently sense and communicate with other nearby vehicles. System-on-chip (SoC) applications in the automotive market have strict circuit performances and reliability requirements for a temperature range of up to 175 0C. This work proposes an analysis of latched-comparators...
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.
Grid connection of distributed generation would have a certain impact on safe and stable operation of receiving-end network, so systematic analysis on it would be significant. The method for comprehensive assessment on effects caused by grid connection of distributed generation on power grid is presented. The assessment system is divided into steady-state operation assessment, reliability assessment,...
The health status assessment of power distribution areas (PDA) can provide a basis for the decision-maker to ascertain the unhealthy PDAs among multiple PDAs. In this paper, an evaluation indicator system of the health status of PDAs is established based on four evaluation indicators. A new data acquisition system is proposed in this paper to enhance the reliability of communication system. The evaluation...
Monte-Carlo sampling method in reliability evaluation has defects of great sampling number and low efficiency. This paper proposed control variable method in power system integrated with wind power unit, considering its feather of small unit capacity and large unit number. The proposed method is carried out on the IEEE RTS79 test system, compares with the conventional Monte-Carlo method and the average...
In order to make full use of the joint sparse characteristics of sparse signals, a new distributed Subspace Pursuit algorithm based on the Subspace Pursuit (SP) algorithm is proposed in this paper. The algorithm improves the support set initialization and update processing of the traditional SP algorithm. During the initialization stage of the support set, the positions of the larger values of inner...

The Integrated Navigation System (INS in brief) is a kind of navigation system with multiple systems, multi-function, high performance and reliability. Its essence is to make...
In order to meet the needs of large capacity, long distance power transmission and nationwide power grid interconnection, China is making great efforts to develop UHV transmission project. Switching overvoltage directly influences the construction cost and operation reliability of UHV transmission system, how to reduce the switching overvoltage deeply is one of the key technical problems that need...
Due to the geomagnetic abnormality in indoor environment, made by various ferrous structural materials such as pipelines, the magnetic signals of a region are regularly different and sustainable. In this paper, we develop an application based on the Android system to implement the indoor geomagnetic positioning. To estimate the pedestrian's position, the real-time geomagnetic sequence measured by...
Many state-of-the-art approaches to multi-object tracking rely on detecting them in each frame independently, grouping detections into short but reliable trajectory segments, and then further grouping them into full trajectories. This grouping typically relies on imposing local smoothness constraints but almost never on enforcing more global ones on the trajectories.,,In this paper, we propose a non-Markovian...
The goal of complex event detection is to automatically detect whether an event of interest happens in temporally untrimmed long videos which usually consist of multiple video shots. Observing some video shots in positive (resp. negative) videos are irrelevant (resp. relevant) to the given event class, we formulate this task as a multi-instance learning (MIL) problem by taking each video as a bag...
The capability to ensure reliability while operating in extreme environments is important for the most demanding automotive applications. Even though pressure sensors are a well-established area in the MEMS industry, improvements in sensor design are needed to deliver reliability and long operational life. This paper reports the design, fabrication and testing of a harsh media backside absolute piezoresistive...
Across the globe nearly 1.6 billion people lack access to electricity, of which many live in rural or remote areas of the developing countries. The extension of central grid for rural electrification is not economically viable due to the geographical placement and low initial power demand. However, for rural villages, systems that are less reliable than grid standards may be acceptable, and allow...
We present a digital system for measurement of neutron spectra in mixed gamma-neutron fields. The signal from a standard scintillation detector is sampled at rate up to 1 GHz, using 12-bit analog-to-digital converters. First stage of the signal processing is performed on a Virtex 6 FPGA and partial results are streamed through a fast Ethernet link to a computer, where the final processing takes place...
Current methods to compare measurement series are based on the comparison of multiple measurement points or fit parameters. These approaches depend on the quality of the fit and are prone to type I error accumulation, when standard statistical tests are used for evaluation. In this work, we present an approach based on a two-sample Kolmogorov-Smirnov test of residuals of data series to a fit in order...
