By establishing a predator-prey automatic SIRS model with saturation infectious force and HollingⅡ functions, we have obtained the conditions of the existence of various equilibriums. Furthermore, the global stability or the local stability of equilibrium has been proved. In this paper, we have obtained the existence and the asymptotical stability of the positive equilibriums when the saturation infectious force is large enough.

In this paper, we introduced new methods in implementing ultra-fast-efficient BCH decoder that frequently used in many applications. A Reformulated inversionless-Berlekamp-Massey algorithm is adopted in order to eliminate the finite-field inverter and to reduce the hardware complexity. Furthermore, we proposed a Direct reformulated-inversionless Berlekamp-Massey algorithm (DriBM). While in the Chien Search stage, the Constant-Factor Multiplication-Free Matrix transform is also introduced to avoid expensiveness which significantly reduce the area and critical path. Moreover, we also developed Extended Fast Chien Search algorithm which significantly reduce computation complexity and the area by nearly 33% compared to Constant-Factor MFTM. Using our proposed design, we design a BCH(15,7) decoder which can reach speed up to 2.2 GHz with total area of is 8170 μm2 using 0.18 μm CMOS standard cell technology. The merits of the proposed algorithms and architecture are very efficient and fast. The implementation of the proposed BCH decoder architecture is also scalable to higher n block lengths and t number of correctable error, by using the same concept as we design BCH(63,51) using the same concept as BCH(15,7). In addition to the parallel BCH Decoder, we also design an area efficient parallel GF multiplier and squarer which minimized the number of logic gates. This design has been implemented and verified on Altera DE2 FPGA using codeword with various error positions and weight (0-2 guaranteed error correction). Due to its low complexity, it is suitable for VLSI implementation and also provide excellent tradeoffs between the correcting capacity, speed and area penalties.

In the traditional laboratory surveillance system, its effectiveness depends on the number of cameras installed, but the price is too high, and most adopt fixed video, and often some dead ends, such as an emergency can not be real-time monitor. The purpose of this study propose a set of the use of a small number of network cameras and wireless sensors developed by combining real-time laboratory safety monitoring system (WebNet System), used in laboratory safety and personnel tracking, on via the computer or 3G mobile phone to remote monitoring for the purpose. In this study, WebNet immediate laboratory safety monitoring system monitoring system compared with the traditional results show that this study has the excellent effect of the monitor.

An AOTF-based hyperpsectral tongue imaging system which can capture both spectral and spatial information of human tongue is developed and used in computerized tongue diagnosis. This new type of tongue imaging system has the advantage of having no moving parts and can be scanned at very high rates. This makes the structure of the new system more compact and more suitable for tongue images capture. A series of hyperspectral images of tongue surface and sublingual veins are captured by using the new system. The automatic tongue segmentation and tongue features extraction based on hyperspectral images are also discussed. Preliminary experiment results show a great deal of potential of this system for computerized tongue diagnosis.

A unified drain current model for undoped or lightly doped double-gate (DG) and surrounding-gate (SRG) MOSFETs incorporating velocity saturation effect are presented in this paper. The unified charge-based core model for undoped or lightly doped DG and SRG MOSFETs is presented first. Caughey-Thomas engineering mobility model with exponent factor n=2 is then integrated self-consistently into the unified drain current model derivation of the two device structure. Extensive two dimensional (2D) and three dimensional (3D) device simulations are performed to validate the proposed model. Symmetry property of the proposed unified current model is obtained with the exponent factor n=2 in Cauhey-Thomas Model.
