On the basis of EST (Equivalent STate hashing) algorithm, this paper researches a kind of test generation algorithm based on search state dominance for combinational circuit. According to the dominance relation of the E-frontier (evaluation frontier), we can prove that this algorithm can terminate unnecessary searching step of test pattern earlier than the EST algorithm through some examples, so this algorithm can reduce the time of test generation. The test patterns calculated can detect faults given through simulation.

Solution techniques for Markov decision problems rely on exact knowledge of the transition rates, which may be difficult or impossible to obtain. In this paper, we consider Markov decision problems with uncertain transition rates represented as compact sets. We first consider the problem of sensitivity analysis where the aim is to quantify the range of uncertainty of the average per-unit-time reward given the range of uncertainty of the transition rates. We then develop solution techniques for the problem of obtaining the max-min optimal policy, which maximizes the worst-case average per-unit-time reward. In each of these problems, we distinguish between systems that can have their transition rates chosen independently and those where the transition rates depend on each other. Our solution techniques are applicable to Markov decision processes with fixed but unknown transition rates and to those with time-varying transition rates.

This paper considers the general filtering problem for a distinct class of two-dimensional (2-D) discrete linear systems, i.e. information propagation in two independent directions, known as discrete linear repetitive processes which are of both system-theoretic and applications interest. In particular, new results on the design of filters with guaranteed levels of performance are developed. These take the form of algorithms for the design of an H infin and l 2 -l infin dynamic output feedback filter which guarantees that the resulting filtering error process is stable and has prescribed disturbance attenuation performance as measured by H infin and l 2 -l infin norms.

An optical current sensor based on the theory of Fabry-Perot interferometer is reported. Theoretical aspects of FP interferometer and optical sensors are described. A structure of the fixed cross beam with a permanent magnet has been designed and the deflection of the magnet under an electromagnetic field leads to the beam displacement. The length of FP microcavity changes with this displacement and the variation is detected by FBG scanning demodulation. The relationship between the measured current and the output light intensity is established and simulation results are also showed herein.

This paper proposes a new mechanism to support Medium Access control (MAC)-level Quality-of-Service (QoS) in IEEE 802.11. Several slots are assembled together to form a super slot, and every slot in the super slot is designated for a given priority traffic to send frames. The slot assignment is done according to the traffic priority. The highest priority traffic is sent at the first slot in a super slot and the lowest priority traffic is sent at the last one. By the arrangement on the sending order, if many stations with different priority traffic want to send frames in a super slot all together, only the highest priority traffic of them can get the transmission opportunity (TXOP). This new priority scheme is robust and provides good performance on throughput, MAC delay and frame dropping probability for the high priority traffic. This new mechanism can improve the performance of IEEE 802.11e EDCA greatly. © 2006 IEEE.

In this paper the structure-based test generation algorithm has been studied for the problem that test patterns are obtained by determined finite faults set in the past. This Algorithm can find out all test patterns one tithe, so faults detection is very convenient. By simulation, the smallest test patterns set can be obtained and faults coverage rate is 100%.

Adopting the traditional object-oriented and component-based methods, the software architecture design pattern can be applied in the concurrent, realtime and distributed fields, which will replace the kind of strong-coupling and process-oriented development predominant in the real-time embedded software to satisfy the needs of the fast development of hardware and communication technology. Combined with the mechanistic design pattern put forward by Gamma et al. (like layer, microkernel, component, etc.), in the light of the view between the subsystem and the component architecture and of the concurrency, correct design pattern is generated by means of pattern incubating, mining or instantiation, which is then applied to develop a robust and scalable architecture for real-time system. As the Component-based Software engineering (CBSE) can effectively enhance the quality and efficiency of the software development process, the technology is introduced to architecture design, offering mature applications by means of framework instantiation. Based on the hybrid design pattern, the architecture and the process of the software become mutually reinforcing and complementary, and both the interior quality and the process quality of the software are guaranteed. © 2006 IEEE.

Detection and prevention of Phenylketonuria (PKU) is becoming more and more important. However, the current methods are either imprecise or time-consuming. We propose a biosensor system based on phenylalanine ammonia-lyase (PAL) immobilized on an ammonia electrode to measure blood phenylalanine for PKU prevention. The biosensor exhibits good linearity from 10-5000 muM and the response time is only about 2 minutes. It remains stable for at least 5 days and less than 20% drop of the original activity after ten day storage at 4 D, while the service life of the biosensor could be up to 30 days. We also develop an intelligent system to ensure optimal conditions for operation and preservation of the biosensor and to make detection more convenient and reliable. All of these advantages indicate that the newly developed method could be a better one for solving the problems of PKU detection
