[[abstract]]This paper mainly treats with the state estimator design of non-linear stochastic systems with state dependent noise. The state and measurement are cormpted by internal noise and exogenous disturbance, ' the exogenous disturbance in system equation is allowed to be stochastic uncertain. Some sufficient conditions on stochastic H-infinity and mixed H-2/H-ifinity filter design are given in linear matrix inequalities(LM1s).
[[abstract]]To integrate GPRS and WLANs, we proposed a GPRS-WLAN Mobility Gateway (GWMG) which resides on the border of GPRS and WLAN systems. The design goal is to minimize the modifications in GPRS and WLANs as that both systems are widely available in the markets already. By deploying the GWMG, users can seamlessly roam between two systems. This paper presents the analytical models to quantify the performance of the design. Handoff latency and buffer size on GWMG are analyzed. The results show that the GWMG could achieve the design goal to effectively integrate GPRS and WLANs. © 2004 IEEE.
[[abstract]]In this paper, we proposed an energy conserving routing protocol in mobile ad hoc network. The goal of our protocol is to reduce power consumption in transmission and hence to increase the lifetime of the whole network. To achieve energy conservation, the transmission power is controlled to the minimum level that packets can be correctly received. To find a proper route, we take into account both the transmission power and the remaining energy of the mobile hosts along the path. We also proposed a route caching strategy to increase the cache efficiency. Simulation results show that our protocol can conserve 10% to 20% more energy than dynamic source routing does. Also, our protocol also have not only longer network lifetime but also lower standard deviation on remaining energy among hosts.
[[abstract]]This paper presents the design and analysis of GPRS-WLAN Mobility Gateway (GWMG) for the integration of GPRS and wireless LANs (WLANs). The proposed architecture leverages Mobile IP as the mobility management protocol over WLANs. The interworking between GPRS and WLANs is achieved by the GWMG which resides on the border of GPRS and WLAN systems. The design goal is to minimize the modifications in GPRS and WLANs as that both systems are widely available in the markets already. By deploying the GWMG, users can seamlessly roam among two systems. Both mathematical analysis and simulation are developed to analyze the performance. The proposed GWMG has also been implemented in a commercial GPRS system. The results show that the GWMG could achieve the design goal to effectively integrate GPRS and WLANs. © 2005 IEEE.
[[abstract]]The transition from reverse-saturable absorption to saturable absorption of the chloroaluminum pthalocyanine solution excited by a giant laser pulse was discussed. It was found that the transition was ascribed not just to the saturation of excited state absorption but also to the outward migration of the solute molecules at the laser beam center. It was observed that while the saturation of excited state absorption occurred within a single picosecond laser pulse, the beam center population decrease was sustained much longer than the pulse duration. Analysis shows that the two mechanisms were distinguished with the Z-scan technique utilizing picosecond pulses with pulse-to-pulse separations ranging from 0.1 to 5.0 s.
[[abstract]]Fuzzy reasoning processors have been employed in many commercial and industrial applications. A high-performance pipelined, single-instruction-stream, and single-data-stream architecture of fuzzy reasoning engine has been designed. Based on this architecture, the proposed VLSI processor for embedded real-time fuzzy logic applications was fabricated in a 0.8-mm CMOS technology. Its computation power can reach 2.5 Million Fuzzy Logic Inferences Per Second (MFLIPS) at a system clock of 20 MHz. In order to efficiently realize fuzzy applications, a software development system under Microsoft Windows has also been designed. For the purpose of showing its effectiveness, we have carried out the experiments to successfully control the crane system. Experimental results have shown the efficient cooperative control of the proposed fuz...

Alcohol consumption during pregnancy can result in fetal alcohol spectrum disorders (FASD), which encompass a range of physical, behavioral, learning, emotional and social disturbances. Many mechanisms for this array of alcohol-derived fetal injuries have been proposed, but none fully accounts for the deficiencies observed. Alcohol is a ubiquitous drug that may affect the brain at any or all stages of development and at multiple sites; regional differences in vulnerability of different brain structures during different periods of exposure have been demonstrated. This study investigates possible mechanisms for the alcohol induced neurodevelopment damage seen as a result of prenatal alcohol exposure, and also includes evaluation of a potential intervention strategy (glutamine). These experiments all utilized the sheep model, which has di...
