Imbalanced load distribution among multiple APs (access points) has become a serious problem in enterprise WLANs. Load imbalance causes inefficiency of network usage and unreasonable resource allocation. We find that users tend to come and leave together, which can lead to fluctuation of network load. We propose a novel online AP allocation scheme (ASC) to keep load balanced when users come and leave...
During the past few decades, many Evolutionary Algorithms together with the constraint handling techniques have been developed to solve the constrained optimization problems which have attracted a lot of research interest. But it's still very difficult to decide when and how to use these algorithms and constraint handling techniques effectively. Some researchers have proposed some general frameworks...
The capability of an intelligent services system is based on a set of services processes, which are often organized into and managed by a process library. In order to react to a outside requirement, the system takes one of the approaches of using a predefined process directly, composing existing process models or generating a new process model based on a search algorithm on demand. Therefore, to decide...
In this paper, a novel approach for defects detection in web inspection based on TMS320DM642 DSP development board is proposed. The whole commercial web inspection system can be divided into three major function units: image capture, real-time processing of line-scanned images and the networking transmission. An innovative line-analysis based threshold detection algorithm is presented. The experimental...
To overcome shortcomings that semantic association in traditional model is just dependent on words instead of their relationships, the concept retrieval model based on description logic is introduced in the paper, and extend reasoning algorithm is proposed. And then on the basis of previous work, a concept retrieval system based on description logic is implemented. The experimentation comes to the...
This article uses the advanced wavelet theory to perform multi-criteria transformation on the medical CT image wavelet in order to obtain directive components. The improved wavelet threshold value law is combined with the wavelet homomorphism filter corresponding to the obtained directive components to remove noise and enhance image effect, finally resulting in the multi-scale (level) enhanced images...
