The detection method of partial discharge (PD) ultrasonic array signals is a new method that applies array sensors and array signals process technique to the PD detection. Moreover, the technique has high signal-to-noise ratio and high reliability. Compared with a full array sensor, degree reduction array sensor is a sparse array detection system, which has advantages of simple structure, low cost,...
As a part of automatic control system of rock roadheaders, the dynamic load identification is of great significance to improve the intelligent level and increase lifetime of roadheaders. In order to solve the problems of rock roadheaders such as complicated operating conditions, difficult dynamic load real-time identification, a recognition method based on multi-neural network and evidence theory...
Recent experimental studies reveal that FinFET devices commercialized in recent years tend to suffer from moresevere NBTI degradation compared to planar transistors, necessitating effective techniques on processors built with FinFET for endurable operations. We propose to address this problem by exploiting the device heterogeneity and leveraging the slower NBTI aging rate manifested on the planar...
Varied Lateral Thickness (VLT) technology is a novel voltage-sustaining technology which has been developed recently. This paper focuses on the static and dynamic operation performance of SOI LDMOS using the VLT technology. Firstly, the VLT LDMOS is optimized by using the TCAD tool to maximize the off-state breakdown voltage. The results show that the drift doping concentration and the breakdown voltage...
Traditional design space exploration mainly focuses on performance and power consumption. However, as one of the first-class constraints for modern processor design, the relationship between hard-error reliability and processor configurations has not been well studied. In this paper, we investigate this relationship by exploring a large processor design space. We employ a rule search strategy, i.e...
High-performance processors suffer from soft error vulnerability due to the increasing on-chip transistor density, shrinking processor feature size, lower threshold voltage, etc. In this paper, we propose to use a rule search strategy, i.e. Patient Rule Induction Method (PRIM), to optimize processor soft error robustness. By exploring a huge microarchitectural design space on the Architectural Vulnerability...
Using wireless mesh network characteristics of multi-hop networks, self-organization and other features, to improve the question of the overlarge quantities of communication task, uneven use of resources lead to the problem of low reliability of network communication. Analyze the factors which affect network reliability in the processes of information communication. And combine with bandwidth, node...
Studying the application and development status of QFD and TRIZ theory, the paper proposes a new innovative design method of energy-saving products to overcome the shortcomings of traditional theories. This new method, which bases on house of quality of QFD, uses TRIZ theory to solve problems and DEA to select solutions. At the end it's obtained with practice that this method is effective.
Since emerged in 2004, Unified Threat Management (UTM) has been used widely to enhance network security protection. Typical UTM device integrates multiple security technologies, therefore its control and management involves various interfaces, message formats, communication protocols, and security policies and so on. Therefore, it is a big challenge to design and implement the configuration and management...
A MRAS (Model Reference Adaptive System) method for evaluation of induction motor speed to achieve speed sensorless vector controlling by the variation of transient reactive power is discussed in terms of traditional methods. A mathematic model is derived, and the reliability of the speed estimator is performed in speed-torque domain using small signal analysis. The simulating model of speed-sensorless...
In China, more and more companies are constructing internal control system as enterprise internal control basic standard (EICBS) was released last year. Based on the data obtained in a survey, we firstly examine the quality of internal control in China companies. Secondly we examine how and to what extent the firm-specific characteristics determine the quality of internal control. We find that size,...
Iris recognition is of great significance in biometric technologies, due to the highest reliability and accuracy. As the first crucial step of iris recognition, iris segmentation is continuously and widely studied. A novel iris location method, based on rotation average analysis of intensity-inversed image, is presented here for iris segmentation: First, it locates the pupil by checking the consecutive...
Instant wireless sensor network (IWSN) is a type of WSN deployed for a class of special applications which have the common requirement on instantly responding for collecting and transmitting sensory data, e.g., volcanic eruption monitoring or nuclear leakage detection. In this paper, having a cluster-based WSN, we present a compensation-based reliable data delivery protocol (CRDD) to collect and transmit...
The synthesis and design problem for reliable tracking controller against actuator faults is studied in this paper. A more practical and general model of actuator faults for linear uncertain systems is presented. Sufficient conditions for the existence of a reliable tracking controller are derived. Then the design of a state feedback reliable controller design is accomplished by means of LMI based...
