It is composed of a set of protocols that utilizes cryptographic algorithms to encrypt and authenticate packets. This security mechanism has been widely deployed to implement virtual private networks (VPNs). To protect data during transmission and ensure data integration after transmission, both of the forward and the inverse cryptographic operations suffer from a very high cost of computation load. To lower down this cost, various hardware accelerators have been developed to offload these operations from the core CPU. Among them, Intel had integrated three security accelerators in its XScale core. On top of them, we had developed software modules to upgrade the performance of IPSec applications. Results show that acceleration has been achieved. In terms of network throughput, hardware-aided solutions have an average of 2.7 times faster than the software solutions.","PeriodicalId":326887,"journal":{"name":"International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121896117","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 paper presents a hybrid approach of a text-mining technique for measuring semantic relatedness among texts. In this work we develop several text classifiers using support vector machines (SVM) method to supporting acquisition of relatedness among texts. First, we utilized our developed text mining algorithms, including text mining techniques based on classification of texts in several text collections. After that, we employ various SVM classifiers to deal with evaluation of relatedness of the target documents. The results indicate that this approach can also be fitted to other research work, such as information filtering, and recategorizing resulting documents of search engine queries.","PeriodicalId":326887,"journal":{"name":"International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122206055","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}

There are several benefits associated with using an unfamiliar platform and development tools in upper-level software engineering courses. The student's lack of familiarity with the development environment forces more time to be spent early on in the requirements and design of the project. In addition, the increasing popularity of mobile computing devices has made handheld programming experience valuable to graduating students in their job searches. This paper addresses the motivation for using handheld device programming projects, the technical issues associated with such projects, and the results of several semesters worth of teaching experience and student feedback.","PeriodicalId":326887,"journal":{"name":"International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123962114","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}

Our purpose is to show alternative approaches to writing tabular specifications and to help practitioners who want to apply such methods by allowing them to pick the best one for their problem. The object for the case study is software used by Dell Products for testing the functionality of the keyboards on notebook computers. Starting from informal documents, we developed a variety of tabular representations of finite state machine specifications and tabular trace specifications. We found that the discipline required by these methods raised issues that had never been considered and resulted in documents that were both more complete and much clearer. The various tabular representations are compared from a user's point of view, i.e., clarity, consistency, unambiguity, completeness, suitability, etc.","PeriodicalId":326887,"journal":{"name":"International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123376789","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 technology has become increasingly important in communication and networking. Routing is one of the most important and difficult aspects in ad hoc network since ad hoc network topology frequently changes. Conventional routing algorithms are difficult to be applied to a dynamic network topology, therefore modeling and design an efficient routing protocol in such dynamic networks is an important issue. One of the meta-heuristic algorithms which is inspired by the behavior of real ants is called ant colony optimization (ACO) algorithm, it can definitely be used as a tool to tackle the mercurial scenarios present in this dynamic environment. In this paper, the author has designed a model, which combines ant colony behavior and queuing network analysis to evaluate end-to-end packet delay in MANET.","PeriodicalId":326887,"journal":{"name":"International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127693805","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}

It treats role as the independent modeling element and introduces RoleOf relationship between business class and role, which makes the business logic and the pattern logic completely separated, thus improves its reusability. Through the extension of UML, the meta-model and semantics of RoleOf relationship, and stereotypes and tagged values used for identify pattern information are provided, it resolves the traceability and overlapping problem.
