High-level synthesis (HLS) tools have vastly increased the productivity of field-programmable gate array (FPGA) programmers with design automation and abstraction. However, the side effect is that many architectural details are hidden from the programmers. As a result, programmers who wish to improve the performance of their design often have difficulty identifying the performance bottleneck. It is...
Network pharmacology which is based on bioinformatics and system biology knowledge has been employed into the field of Traditional Chinese Medicine (TCM) researches in recent years. In order to summarize current available bioinformatics databases, especially those can be used for TCM formulae study; a systematic search of Chinese literature by May 2017 was conducted. Results showed that research methods...
This paper focuses on the systematic design and development of an optimized embedded system platform from ground up to handle special real-time requirements of control applications. An embedded system is usually embedded as a part of a complete device including hardware and mechanical parts, and both the hardware system and the software system are tailored and optimized to realize specific functions...
The under-determined direction of arrival (DOA) estimation problem for a mixture of circular and non-circular signals is studied in the context of sparse arrays and a novel compressive sensing based DOA estimation algorithm is proposed. Compared to a direct application of existing compressive sensing based DOA estimation algorithm, the new one can make a more effective use of the degree of freedoms...
Some sleep disorders, such as sleep apnea, restless legs syndromes (RLS), and periodic limb movement disorder (PLMD), require a full-night sleep monitoring for diagnosis. Conventional sleep monitoring devices are disturbing and inconvenient for daily scene applications. In this poster paper, we propose a sleep monitoring system by embedding RFID tags into bed cloth and realize two main functions:...
The active-forced-commutated (AFC) bridge for high-voltage (HV) DC transmission has recently been proposed, which operates low-loss thyristor valves in the manner of a voltage source converter (VSC) with the assistance of a self-commutated full-bridge (FB) chain-link (CL) circuit, creating a hybrid VSC solution which retains the key advantage of high-efficiency performance found in conventional line-commutated-converters...
The correct analysis of power system transient stability is of great significance to the safe and stable operation of power system and the construction of smart grid. Based on the basic theory of Extreme Learning Machine (ELM), this paper studies the transient stability of power system. Firstly, the simulation model is built to simulate power system for obtaining data sets. Then, the implementation...
The B-spline Gaussian mixture probability hypothesis density (BS-GM-PHD) filter can track an unknown number of extended targets and estimate their shape. However, the target tracks might be inaccurately associated when targets are closely spaced. This paper presents a novel track association approach for the BS-GM-PHD filter using the estimated shape information. First, a shape table (ST) will be...
This paper addresses a new type of distributed assembly permutation flow-shop scheduling problem, where the single distributed assembly line in the conventional version is replaced by multiple assembly factories. Then within this scheduling framework, we consider two transportation problems. One is the transportation of jobs between origin and the assigned processing factory by obeying the capacity...
For power semiconductor devices, such as IGBTs, MOSFETs and FRDs, a high area efficiency of the edge termination structure can enlarge the active area and thus improve the current capacity for a given chip area. In this paper, a double-sided edge termination (DSET) is proposed for the first time. Simulation results show that it can improve the breakdown voltage by about 42% without increasing the...
For the first time, this paper reveals and explains the detailed contribution of the main-junction lateral resistive zone to the ruggedness of high-voltage fast recovery diodes during a harsh reverse recovery. And its optimized width is discussed.
This paper presents a compact bandpass filter based on stacked eighth-mode substrate integrated waveguide (EMSIW) resonators. By properly constructing the feeding and coupling topology of four EMSIW cavities, the proposed filter not only exhibits compact size, but also achieves enhanced selectivity by virtue of its three transmission zeros (TZs). A novel cross-coupled structure which contributes to...
In cloud storage systems, the use of erasure coding results in high read latency and long recovery time when drive or node failure happens. In this paper, we design a parity independent array codes (PIT), a variation of STAR code, which is triple fault tolerant and nearly space-optimal, and also propose an efficient single-failure recovery scheme (PITR) for them to mitigate the problem. In addition,...
The softness and the switching losses are the key characteristics to evaluate the quality of the ultra voltage power diodes, especially for high frequency application. In this paper, we applied the Controlled Injection of Backside Holes (CIBH) structure to the 10kV SiC diode based on TCAD, by which, the softness and snap-off characteristics of the diode is significantly optimized compared with conventional...
The requirements for lead-free electronics lead to the development of new Pb-free solders. The Sn-3.0-Ag-0.5Cu (SAC305) is one of them and is widely used in the lead-free solder market. But the melting point of it, 217°C, exceeds that of traditional Sn-37Pb solder. The lower melting temperature of lead-free solder are needed to meet the requirements of the manufacturing process that depend on conventional...
Through the continuous collection and in-depth analysis of the quality monitoring data of colleges and universities, we combine the efficiency processing of big data and data evaluation, monitor the status of higher education normally, and construct a higher education quality monitoring and evaluation platform based on Spark. This platform is teaching centered with schools as its basis, including...
Conventional reliability demonstration test based on statistical method is widely used in industry as it is simple and convenient to apply. But for the products with high reliability and long life, this test method fails to satisfy the demand for short cycle and low cost, and is liable to cause the phenomenon of over-test and short-test. This paper gives a step-stress accelerated sequential probability...
Accelerated degradation testing (ADT) Bayesian optimization design can determine prior distribution of model parameters by prior information, which avoiding the uncertainty to the result of design brought by assuming parameter selection arbitrarily. However, different people may have different tendencies when choosing prior distributions through the same prior information. It may result in different...
Fixed wing canard aerodynamic forces during flight control process was used as an energy source for internal control mechanisms, based on this kind of situation, control system was power up in flight control process, so we needed to initialize roll attitude angle of the fixed wing canard in flight. In this paper, a new algorithm based on aerodynamic synthesis vector analysis for the roll attitude...
Diastolic time (DT) may reflect the functioning status of cardiac relaxation/diastolic filling. Previous studies shown that beat-to-beat variation in RR interval (i.e., HRV) is preferentially expressed in the variation in DT series, raising up a question that whether DT possesses intrinsic variation, or whether the DT variation is simply a surrogate of HRV without additional information. In this study,...
