This paper is concerned with sampled-data based reliable control for switched stochastic delay systems with actuator failures and nonlinear perturbations under asynchronous switching. By the multiple Lyapunov functional approach and the average dwell time technique, sufficient conditions are given to guarantee the mean-square exponential stability of switched stochastic delay systems with actuator...
For the miniaturization and multifunction of electronic devices, the vertical interconnection technology has been developed to replace the traditional planar packaging technology. The interposer connection using double-side solder bump is used as the vertical interconnection technology in this study. Three kinds of solder bumps with different diameters of 0.76mm, 1.2 mm and 2mm were prepared and mounted...
Three-dimensional structure has been achieved using interlayer connecting technology with double-side solder bump and the lifetime of the solder joints under thermal shock test has been forecasted by finite element method. The simulation result presents that the stress at the interface between 0.76mm solder bump and PCB is evidently higher than that in other places. The interface between 0.76mm solder...
Most existing weakly supervised localization (WSL) approaches learn detectors by finding positive bounding boxes based on features learned with image-level supervision. However, those features do not contain spatial location related information and usually provide poor-quality positive samples for training a detector. To overcome this issue, we propose a deep self-taught learning approach, which makes...
This research examines the influence of logistic service supply chain network (hereinafter referred to as the LSSC network) to the growth of logistic service integrator (LSI) from the perspective of social network. We divided the LSSC network into five sub-networks, they are social network, reputational network, marketing network, logistic collaboration network and logistic innovation network. We...
Operational ocean observing system (OOOS) can meet the needs of marine disaster prevention and reduction, safeguard socio-economic development in coastal zones, and promote marine resource exploitation. As a solid foundation for the establishment of the OOOS, operational ocean observing equipment (OOOE) is attached great significance across the world. Three kinds of OOOEs in China are introduced and...
This paper proposes a distribution network reliability cost-benefit analysis and optimization method. When carrying out the distribution network planning to improve the reliability of power supply, through analyzing a variety of major reliability improvement measures, each measure's reliability cost-benefit analysis curve decomposed can be obtained. Then the curves corresponding to all the measures...
With the development of the equipment, general quality characteristics (GQCs) are getting more and more important. This paper mainly focuses on the procedure and several methods for identification of GQCs.

To meet the need of high rate and high reliability for next generation of wireless mobile communication system, in this paper, we designed a new communications system of OFDM-IDMA based on QC-LDPC. The performance under different coding rate, different length of frame is analyzed, and we also compared the performance with the system based on convolutional codes, the simulation results show that this...
Due to large variations in temperature in VLSI circuits and the linear relationship between metal resistance and temperature, the delay through wires of the same length can be different. Traditional thermal aware floorplanning algorithms use wirelength to estimate delay and routability. In this work, we show that using wirelength as the evaluation metric does not always produce a floorplan with the...
Analyzing the limitation of traditional fuzzy-integral measure method, this paper puts forward an improved fuzzy-integral measure method. With this method, decision-maker will find deficiencies of the measure object by changing numerical value of parameter e, based on which, they can establish and implement corresponding strategies. At last, this paper makes a demonstrated analysis, which proves the...
A 1.0 V to 1.8 V mixed-voltage I/O buffer implemented with 90-nm 1-V standard CMOS devices is proposed. By using a dynamic gate bias generator to provide appropriate gate drive voltages for the output stage, the I/O buffer can transmit 2×VDD voltage level signal without any gate-oxide overstress hazard. Besides, the leakage current is eliminated by adopting a floating N-well circuit. The maximum data...
Management Research Methodology (MRM) is the compulsory curriculum for candidates of Master of Engineering, which can solves the difficulties of management, enhances the efficiency. Currently there are more than 20,000 candidates in the field and deficient professional teachers, let along the communication and discussion. With the MRM teaching practice, the author induced the issues and reflection,...
Spectrum sensing is an important component of cognitive radio technology. Cooperative spectrum sensing is regarded as the most promising method to improve the reliability of spectrum sensing. However, such cooperation also introduces overhead traffic of control signaling and result transmission which consumes more power in battery operated mobile terminals. In this paper, an RLECSS (run-length encoding...
How to build the mutual trust among peers in P2P network is crucial to secure distributed P2P applications. In this paper, we propose to use Mamdani-type fuzzy inference techniques in the design of P2P trust systems based on collecting and aggregating peers' trust value, which can better handle uncertainty and fuzziness in peer trust. There are five parts in the process of P2P trust fuzzy inference:...
