There are many approaches for finding solution to the TSP. In this paper we used combination of local search heuristics and genetic algorithm (GLS) that has been shown to be an efficient algorithm for finding near optimal to the TSP. We also evaluate the run time behavior and fitness of our approach and compare it with other methods. A reasonable result is obtained and the proposed algorithm is able to get to a better solution in less time.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117133379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Image, audio and video are some popular media for steganography. But text is ideal for steganography due to its ubiquity and smaller size compared to these media. However, text communication channels do not necessarily provide sufficient redundancy for covert communication. In this paper, a new approach for steganography in Microsoft Word documents is proposed. The main idea is that setting any foreground color for invisible characters such as the space or the carriage return is not reflected or viewed in the document.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124822691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present new method to construct a general student project allocation model (SPA-(s, p)) in which the lecturers have preference lists over pairs (student, project), and the students have preference lists over projects. SPA-(s, p) is turned out to be very useful in combination between the student project allocation models with preference lists over students (or projects). Our model proposes several ways to construct the lecturer's preference lists which give us higher efficiency and accurate results. Furthermore, we present algorithmic issues for SPA-(s, p), the algorithm yields a stable matching of students to projects, which respects the preference lists and capacity constraints.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122502886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nvidia’s CUDA general-purpose graphical processing unit (GPGPU) architecture can greatly benefit single instruction multiple thread (SIMT) styled, computationally expensive programs. Video encoding, to an extent, is an excellent example of such an application which can see impressive performance gains from CUDA optimization. This paper details the experience of porting the motion JPEG 2000 reference encoder to the CUDA architecture. Each major structural/computational unit of JPEG 2000 is discussed in the CUDA framework and the results are provided wherever required. Our experimental results demonstrate that the CUDA based implementation works 20.7 times faster than the original implementation on the CPU.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124165793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on this information finally the reference point and reference orientation will be obtained. The proposed method is of high accuracy and performance and at the meantime tolerates displacement and rotation of the input fingerprint. This can be applied to all classes of fingerprints especially to problematic arch class ones.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130182192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of induction motors is rapidly and increasingly growing in the industry especially in highly important sectors. This leads us to a serious focus on their operation and their availability. The early detection for motor deterioration can increase plant availability and safety in economical way, help to avoid expensive failures, reduce coasts and the fault number. Many publications have investigated the detection and diagnosis of short circuit fault in electrical machines supplied directly online. This paper presents a technique based on spectral analysis of stator currents to detect short-circuit fault in the stator using a mathematical model of three-phase squirrel cage induction motor under stator short-circuit fault. The simulation show the impact and the effectiveness of failure. The tests are validated by numerical simulation and the obtained results clearly show the possibility of extracting signatures to detect and locate faults.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130602639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
