A novel philosophy of secure mobile agent model which is based on trust model, risk evaluation and cryptography is proposed in this paper. Compared to current related research, our dynamic model can update in real time and is comprehensive for combining subjective and objective estimation. In addition, this model is broadly adaptive due to its flexibility. Trust and trust relationship are defined on secure problem as while as character of trust itself which are faced when analyzing mobile agent, and trust update function and recommender evaluate function which are already existent are improved. Finally, secure problems which might be brought by trust are discussed.

This paper proposes to adopt the goal-oriented computing as a paradigm of computing and software development for industrial ubiquitous computing. We analyze several planning techniques and conclude that partial conditional HTN is most appropriate for goal-oriented computing within the pervasive industrial environment, in view of software engineering. We propose the language and algorithm required for such goal-oriented computing.

The safety of producing is a very important thing in the industry. But in some dangerous factories e.g. coal mines, circumstances are not allowed to deploy wires. So we bring in the ad hoc wireless sensor network to measure the key physical elements in the workshop. As soon as there are some signs of the accident or the accident has just happened, the system will know it and give the alarm to workers. Our system uses the AOA (angle of arrival) method with the RSSI (received signal strength indicator) filter to get the position of workers. And we propose an improved divisional Dijkstra algorithm to calculate the escape way for the first time to our acknowledgment.

Analyzed here is the physical interpretation of objective function of semi-supervised fuzzy C-means (SS-FCM) algorithm and its coefficient alpha. A conclusion-Stutzpsilas modification to the objective function of Pedrycz is much clearer: unlabeled samples involves in unsupervised learning of FCM, labeled samples involves in unsupervised learning with coefficient (1-a) and participate in supervised learning with a, and when a=1 or 0, the SS-FCM degrades to FCM-is illustrated. The corresponding alternately optimizing algorithm of SS-FCM with fuzzy covariance is provided. The experimental results show that: 1) Modified algorithm has the same semi-supervised role and has much clearer physical interpretation. 2) Using FCM algorithm to assign membership for labeled samples is better than using random number. 3) SS-FCM with fuzzy covariance and a small number of well-selected labeled samples can effectively improve the accuracy and convergence speed.

Position awareness is a desirable feature for many applications of Wireless Sensor Networks. The Received Signal Strength Indication of a radio channel provides a feasible way of estimating distance between nodes because its use doesnpsilat require any additional hardware but a radio transceiver. The main drawback of using RSSI is its instability and interference susceptibleness noticed in real environments. This work shows an evaluation of a location algorithm for wireless sensor networks and presents a new calibration approach that substantially improves the trustworthiness in its results. The results show that adequately adjusted RSSI measurements can be successfully used for localization in wireless sensor networks.

The external controller (EC) of a series flexible AC transmission system (FACTS) device, which is the series capacitive reactance compensator (SCRC), can provide effective damping of low-frequency oscillations in a power system. The saturation limiter in the EC is used to enforce practical limits resulting from system restrictions such as equipment and component ratings. In this paper, the effect of a saturation limiter on the overall system dynamic behavior is analyzed. Also, a systematic nonlinear tuning method is proposed to determine the optimal values for saturation limits based on the sensitivity trajectory analysis.

An optical inspection apparatus was prototyped for examining BioCD samples, and an automatic focusing mechanism using an embedded bio-image feedback mechanism was built in to control the focusing lenses system as to obtain adequate images on the image sensing chip, where sharpness of the captured images are evaluated and compared for subsequent motor movements. Over the motor course motion intervals, piezoactuator minute adjustments are henceforth triggered in fine movements to obtain clear images of the designated layer within inspected BioCD samples. The prototype is featured in its Linux OS based application on an ARM platform, which can execute a variety of servo-motions, including fine motions through implementing piezo-actuations, once the assistances of processed bio images are employed.
