This paper presents an automatic gait recognition system that recognizes a person by the way they walk. The gait signature is obtained based on the angle and the contour of the silhouette. For each image sequence, background subtraction is used to extract moving silhouettes of the walker. The silhouette is divided using three parameters: the perimeter of the contour of the silhouette, the area of the silhouette and the angle between right leg and left leg. Principal component analysis (PCA) was then applied to this dataset in order to reduce the dimensionality. The perimeter of contour and the area of each silhouette was added to the dataset. This paper applies dynamic time warping to distinguish between the different gaits of human subjects. The performance of the proposed method is tested using CASIA database B. Recognition results show this approach is efficient.","PeriodicalId":137864,"journal":{"name":"2012 International Conference on Information Technology and e-Services","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115234549","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}

An efficient bandwidth reservation mechanism in neighboring cells is important in handoff process, particularly when the handoff traffic is heavy. As the next generation wireless networks cater for various kinds of applications with varying degree of QoS parameters, resource management is an important part in order to optimize the overall system performance. The performance of a wireless network is bounded by the efficiency of resource management. The objective is lessening the handoff call dropping probability by using future network traffic load and responding properly to it. In prediction based resource reservation, a priori estimation of the future traffic load affects the process of resource reservation. Our scheme is compared through simulations with other schemes. The simulation results show that our proposal provides better performance in terms of handoff dropping probability.","PeriodicalId":137864,"journal":{"name":"2012 International Conference on Information Technology and e-Services","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114061911","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}

Over the last few years, the aspect oriented paradigm has matured and gained widespread industrial support at the programming phase, while aspect oriented modeling (AOM) is still a fertile field of research. Due to its substantial and crucial importance, the application of aspect orientation at the design stage in software development process has interested many researchers. Recently, numerous works have attempted to provide aspect oriented support at the model level, in various forms that many of which were based on UML, however, there exists no generic AOM language that is capable of supporting all the concepts introduced by the different aspect oriented languages, such as AspectC++. Due to the substantial importance, and to the large use of AspectC++ at the programming level, in software development process, we propose, in this paper, a UML profile for AspectC++ language, which aim to provide AspectC++ specific modeling facility, allowing the modelers to produce aspect oriented models which conform to this language.","PeriodicalId":137864,"journal":{"name":"2012 International Conference on Information Technology and e-Services","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114323468","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}

Therefore, fragmentation and proper allocation of fragments across various sites of the network is considered as a key research area in distributed database environment. However, the issue of allocating fragments to the most appropriate sites is not an easy task to perform. In this paper, a synchronized horizontal fragmentation, replication and allocation model in the context of relational database is proposed. A heuristic technique to satisfy horizontal fragmentation and allocation using a cost model to minimize the total cost of distribution is developed. Experimental results are consistent with the hypothesis confirming that the proposed model can efficiently solve dynamic fragmentation and allocation problem in a distributed relational database systems.","PeriodicalId":137864,"journal":{"name":"2012 International Conference on Information Technology and e-Services","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124316986","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}

A face recognition system aims at recognizing a face in a manner that is as independent as possible of these image variations. Such variations make face recognition, on the basis of appearance, a difficult task. This paper attempts to overcome the variations of facial expression and proposes a biological vision-based facial description, namely Perceived Facial Images (PFIs), applied to facial images for 2D face recognition. Based on the intermediate facial description, SIFT-based feature matching is then carried out to calculate similarity measures between a given probe face and the gallery ones. Because the proposed biological vision-based facial description generates a PFI for each quantized gradient orientation of facial images, we further propose a weighted sum rule based fusion scheme. The proposed approach was tested on three facial expression databases: the Cohn and Kanade Facial Expression Database, the Japanese Female Facial Expression (JAFFE) Database and the FEEDTUM Database. The experimental results demonstrate the effectiveness of the proposed method.","PeriodicalId":137864,"journal":{"name":"2012 International Conference on Information Technology and e-Services","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122492573","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}

Healthy and malignant tissues have different dielectric properties in the microwave frequency region, therefore, the dielectric properties of human body's tissues are generally different from other contraband materials. Consequently the dielectric data analysis techniques using microwave signals can be used to distinguish between different types of materials that could be hidden in the human body, such as explosives or drugs. Other concerns raised about these particular imaging systems were how to build them cost effectively, with less radiation emissions, to overcome the disadvantages of X-ray imaging systems. This paper will discuss in details how microwave tomography scanning could overcome the challenge of imaging concealed objects in the human body and prove the concept of detecting lower values of dielectric properties using image reconstruction.","PeriodicalId":137864,"journal":{"name":"2012 International Conference on Information Technology and e-Services","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116183326","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}

With the advent of ontologies, an important progress has been done with the explicit representation of data semantics with data. In this paper, we are interested in the use of domain ontologies as a semantic enrichment for traditional databases. Our first aim is to help the user in his search when his initial query doesn't return any result. So, we propose an ontological approach for SQL query expansion based on different refinement types. Our approach is described by a generic algorithm that can be used with any traditional database.","PeriodicalId":137864,"journal":{"name":"2012 International Conference on Information Technology and e-Services","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116430030","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}
