In many cases, suitable models do not exist and building these from scratch is a costly effort. A potential approach to bootstrap this process is to generate models with reverse-engineering methods. Potential sources of information for such models include user sessions, existing test cases, and field data. All of these can be seen as different forms of test data. However, using existing test cases as a basis to create a model for test generation raises the question of what is the benefit over the previously existing tests. This paper aims to answer this question by evaluating the benefits in terms of a practical case study.","PeriodicalId":117236,"journal":{"name":"2012 Ninth International Conference on Information Technology - New Generations","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130826485","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 service represents either a part of or a complete business process, which in turn depicts the life cycle of a Business Object (BO). A number of actions constrained by a set of business policies cause the BO to transit from an initial state to a final state during its life cycle. The constraints would vary for different customized business processes. To engineer reliable service based systems it is crucial to verify the reachability of the desired final states of the BO model against a given set of constraints. We propose the formal specification of a constraint-driven BO model, and thereby, present a verification tool to validate the life cycle of the BO model given a set of constraints. The core object and its constraint-driven life cycle are modeled separately for flexibility and customizability. We also define a language specification to represent our BO model and the business goals. The specification is automatically interpreted by our verification tool, which outputs a graphical view of the life cycle and a textual report of the validation results.","PeriodicalId":117236,"journal":{"name":"2012 Ninth International Conference on Information Technology - New Generations","volume":"55 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120920415","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}

This method depends on calculating the summation of the difference between images of a specific slice that we work on it, then applying thresholding on the resulting image to get the region of interest. To validate our method, we compare between our results and results of another method used in localizing the position of the heart which depends on the standard deviation. We worked on images of 14 different patients, come from STACOM database. We achieved by this method good results in determining the position of the heart. This method has different advantages like: it works on different contrast images, fast, and fully automatic.","PeriodicalId":117236,"journal":{"name":"2012 Ninth International Conference on Information Technology - New Generations","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121367108","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}

To speed up computation and extend the simulated area, a sound rendering system based on the two-dimensional Digital Huygens Model (DHM) with timing sharing architecture is designed and implemented by a Field Programmable Gate Array (FPGA) chip XC5VLX330T. Compared with the DHM system with the traditional parallel architecture, the proposed system implemented by a FPGA chip extends about 20 times in simulated area, and speeds up 1.47 times against the software simulation carried out in a computer with an AMD Phenom 9500 Quad-core processor (2.2 GHz) and 4GB RAM. The system is relatively easy to cascade many FPGA chips to work in parallel in real applications.","PeriodicalId":117236,"journal":{"name":"2012 Ninth International Conference on Information Technology - New Generations","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121128858","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}

Overlay graphs based on geographic clusters constructed for wireless networks, modeled as 2D graphs, are generally nonplanar and planar graph routing applied on such overlay graphs may fail. Existing planarization algorithms create planar overlay graphs, when the network graphs obey assumptions like Unit Disk Graph (UDG) property. However, in real wireless networks due to radio range irregularities they fail to create connected planar graphs for connected network graphs. We propose a new planarization algorithm for overlay graphs based on the localized link removal and addition based planarization algorithm. Theoretical analysis shows that planarized graphs created by our algorithm are always planar and connected for connected UDG modeled networks. Evaluation of our algorithm on Log Normal Shadowing model, a realistic wireless model, shows that our algorithm creates connected networks in almost all simulations. Moreover, the probability of getting planar graphs is really high compared to the existing planarization algorithms.","PeriodicalId":117236,"journal":{"name":"2012 Ninth International Conference on Information Technology - New Generations","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121416062","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 SBM website displays and shares each user's bookmarks. The SBM service aggregates the number of users who bookmark a given Web page and provides useful information as a result of these aggregations. However, an increase in the popularity of the SBM service and in the number of the users of the SBM service results in an increase in the amount of SBM SPAM. In addition, the SBM service generates irrelevant information to many users because of the aggregation of a large number of bookmarks, we call this problem \"SBM pollution.\" In this paper, we propose a method for countering the problem of SBM pollution based on the degree of bookmark similarity. The proposed method creates blacklists that contain lists of users having a high degree of bookmark similarity. Based on the created blacklists, the number of bookmarks of the Web pages influenced by SBM pollution is reduced. From the results of the performance evaluation, we show that our method reduces the number of bookmarks of most Web pages influenced by the SBM pollution to a great extent.","PeriodicalId":117236,"journal":{"name":"2012 Ninth International Conference on Information Technology - New Generations","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121611737","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}

This of course depends on the type of software as well. If it is banking or tax software then, security is of concern. However, in most cases the thought rarely crosses the average users mind. That is until something happens to the system or information the system may hold. This way of thinking is very similar to the way some software is created. The software's features, usability, and interface are normally at the forefront. On the other hand the software's security is just an afterthought for many developers. While software is developed in a very intricate process, it does not currently stress security. In this paper, we will describe different approaches that have been recently researched to help create more secure software. Although these approaches will be introduced separately, using a combination of two or all three together would be the most secure combination.","PeriodicalId":117236,"journal":{"name":"2012 Ninth International Conference on Information Technology - New Generations","volume":"137 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130876317","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}
