The problem of finding a minimum vertex cover (MinVC) in a graph is a prominent NP-hard problem of great importance in both theory and application. During recent decades, there has been much interest in finding optimal or near-optimal solutions to this problem. Many existing heuristic algorithms for MinVC are based on local search strategies. Recently, an algorithm called FastVC takes a first step...
With the developing of technology and economic of society, skilled workforce has been playing as the key role through the trend of prosperity. Project scheduling problems with multi-skilled workforce constraints (PSPMSWC) have become a research hotpot in the field of human resource allocation and project scheduling. Following the description and model of the PSPMSWC, a hybrid Benders decomposition...
Binaural hearing-aids are under intensive study nowadays. The information exchange across both ears provides an opportunity to perform the blind source separation to enhance the signal SNR. This study combines the conventional InfomaxICA with our proposed novel algorithms: binaural delay compensation, minimum-interference initial de-mixing guess and low power design concept, for a real-time binaural...
Ad Hoc networks is recently a hot spot in wireless network researching domain. The design of routing algorithm, which is as the core layer technology in Ad Hoc networks, has drawn great concern. In response to the drawbacks of traditional routing protocols such as bad convergence and providing no QoS guarantee, this paper gives the way to construct node vector function to represent QoS indices in...
A solution is urgently expected to meet the higher-quality web service requirements of various applications on the limited bandwidth of internet. This paper presents a new scheme of load balance of web cluster servers, making possible the service of the two-class priority station polling system under the mixed policy of exhaustive and gated services, optimizing the services of the system in time of...
License plate recognition system (LPR) plays an important role in many applications such as access control, traffic control, and the detection of stolen vehicles. A LPR system can be classified into the detection and recognition parts. Improvement of the detection part will be discussed in this paper. Binarization of plate images is one of the major tasks of detection which consumes huge processing...
