The manufacturing equipment used in a manufacturing line is the result of a long learning process, and may be in a totality a result of internal development, imitation (copy), external acquisition, parallel replication, combination/permutation and selection of multiple capabilities and know-how. Investments in manufacturing technologies are, by and large a non-reversible fact, it represent long-term...
Aim at the high computational complexity of level set methods has excluded themselves from many real-time applications. An improved image segmentation method using the fast level set algorithm is proposed in this paper. The algorithm adopts improved fast level set base on single list to realize the curve evolution, which simplifies the fast level set method. Avoiding the traditional level set methods...
The mechanism of active counter-attack on worms has been developed and studied for several years. The worm vaccination, a kind of active counter-attack on worms, has some preliminary results. But further research is still required. In this work, we explored a new vaccine to promote the release time through ana-lyzing the structure proposed by Castaneda F, and presented its structure and generation...
Use the Petri net theory and studied out a synthetical expression method of static state and trends behavior in fire control system fault diagnose. The method may be convenient and succinct for fault phenomenon of multilayer rank order and many route. Amount of work is simplified in the fault diagnose system. The fault information characteristic, fault information molde and propagation behavior fashion...
This paper firstly examines the traditional vehicle styling evaluation methods and issues, and then presents a new approach which uses ANN (artificial neural network) to build an expert system for bus styling evaluation. It describes the key technical issues of quasi-three-dimensional bus styling evaluation expert system from data collection, graphical pre-processing, graphics feature extraction,...
One dimensional cellular automation traffic flow model is suitable for simulating the traffic flow of freeway and circle line of round-the-city traffic. The mixed traffic flow, which is composed of different types or performances motor vehicles, is the common phenomenon in road traffic. On the periodic boundary condition, motor vehicles mixed traffic flow of one-way and single lane is the target of...
The need for quality improvement in software has led to emphasis on software process. But during process enactment, deviations inevitably occur and have to be managed Control limits are established and when the actual process fall outside the control limits, repairing action is taken to bring them under control. Due to lead lag, action has to be taken before deviations reach the control limits. And...
Agile methods of developing software such as extreme programming (XP), are becoming increasingly important for the rapid development of software applications. The paper describes a system dynamics model of the XP development process which can be used to quantitatively evaluate the software process and studies the effect of XP practices by simulation.
Inherent uncertainty and unreliability of data exists widely in emerging applications, like sensor network based ubiquitous computation, results output in information extraction and data integration, etc. Multidimensional skyline analysis is crucial to multicriteria decision-making. Although previous work has addressed skyline computation over traditional data stream, skyline computation over probabilistic...
Planar transformers are a good solution for high power density high frequency switching-mode power supplies (SMPS), their research and application are growing in the last decade. Although these kinds of transformers provide a distinct advantage over the traditional transformer, the high frequency parasitic effects have a great influence on the transient performance. This paper presents a method to...
