In this paper, an adaptive method for detecting abnormal activities in video surveillance is proposed. In this method, a multi-Gaussian distribution called activity model is used to model a moving object activities. The activity model parameters are updated to satisfy the object motion attributes in a real-time when every new frame comes, and at same time this moving object current activity can be recognized by means of its possibility in the activity model. The advantage of this method is that the proposed activity models can update itself adaptively to match the current motion style of the object. The models are robust to the light change in the style of the object activity, and they are sensitive to these activities that do not meet the models. Several experiments are given to show that the proposed method is efficient. ©2008 The Institution of Engineering and technology.

The traditional electronic jamming pod depends on the power supply of the carrier. Limited by the power supply of the carrier, its ability of electronic jamming is weak, and the difference between the power supply system of the pod and the carrier makes the loading flexibility of the electronic jamming pod poor, which restricts the improvement of the performance of the electronic jamming pod. Under this background, this paper puts forward three schemes of autonomous power generation and refrigeration integrated system of electronic jamming pod. Based on the proposed system scheme, the system simulation model is established to simulate and compare the maximum effective power generation and refrigeration capacity of electronic jamming pod in the whole flight envelope and the fuel penalty of the system in the whole mission curve. The results show that the maximum effective power generation of system scheme 1 is greater under the same working conditions in the whole flight envelope, and the overall cooling capacity of system scheme 3 is stronger. Under certain power generation and cooling demand, the applicable flight envelope range of system scheme 1 is larger when the altitude is more than 4000m, while the total fuel penalty of system scheme 1 is smaller for the given flight mission curve. © 2022 IET Conference Proceedings.

In the process of missions, how to transmit messages to the destination node quickly is a crucial issue for UAVs. Some existing methods show bad effects such as low delivery ratio, long delay, large average hop count, and high ping-pong effect ratio, thus this paper proposes a new algorithm. By considering the position of all UAVs at each moment, UAVs can obtain optimal message transmission, thus get the optimal path for the message to reach the destination node. After doing simulation experiments with the existing algorithms as DTNgeo, DTNclose and DTNload, the DPTM algorithm is superior to those in terms of delivery ratio, delay, hop count and ping-pong effect ratio. © 2020, ICST Institute for Computer sciences, Social Informatics and Telecommunications Engineering.

In order to realize the accurate positioning and recognition effectively of the analog circuit, the feature extraction of fault information is an extremely important port. This arrival based on the experimental circuit which is designed as a failure mode to pick-up the fault sample set. We have chosen two methods, one is the combination of wavelet transform and principal component analysis, the other is the factorial analysis for the fault data's feature extraction, and we also use the extreme learning machine to train and diagnose the data, to compare the performance of these two methods through the accuracy of the diagnosis. The results of the experiment shows that the data which we get from the experimental circuit, after dealing with these two methods can quickly get the fault location. © 2016 ACM.

From the viewpoint of mission's completion, the occurrence of any failure or safety accident is decided by multiple complex and dynamic factors. The safety analysis methods in present only focus on failure modes in system itself, rather than the whole mission system dynamical process, the Ground Proximity Warning System (GPWS)'s mission dynamic safety modeling was presented based on SoTeRiA in this paper. Combining with the technical system risk model, maintenance process model and organizing risk model, the model of dynamic safety analysis was established. Case study in the end shows the effectiveness of the proposed method

In this paper, we propose open bisimulations for open processes in higher order π-calculus. The equivalence of open bisimulations and other bisimulations for open processes is proved. Furthermore, we present a symbolic operational semantics of higher order open processes, and give some symbolic bisimulations for higher order processes. The relation between symbolic bisimulations and other bisimulations is also studied. At last, we introduce a higher order π-calculus with sum and conditional operators, then we study open bisimulations and symbolic bisimulations for this calculus. © 2010 IEEE.

In this paper, we first propose a specification approach combining interface automata and Z language. This approach can be used to describe temporal properties and data properties of software components. A branching time logic for ZIAs is presented. We then give an algorithm for model checking this logic on ZIAs with finite domain. Furthermore, we present a mu-calculus logic for ZIAs, and give a model checking algorithm for this logic.
