However, aspect-oriented programming (AOP), a relatively new programming paradigm, has properties that other programming paradigms do not have. These characteristics bring new challenges and issues not present when testing other types of programs such as object oriented programs (OOPs). So this new paradigm can not provide correctness by itself, and thus it also, like any other programs, requires the use of systematic testing approaches to produce validated and high quality software. This paper surveys the research on testing AOPs, the testing approaches that are being proposed, and issues that arise when testing AOPs. The effectiveness of proposed approaches is compared in terms of their ability to find different kind of faults as described by [6]. By making comparison on AOPs testing approaches, a better understanding of these approaches and issues related in testing AOPs is provided, as well as conclusion about existing state of research in this area and future trends for testing of aspect-oriented is identified.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128461952","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 location-based service (LBS) is one of the technologies providing the services adoptively according to the changed user position. The existing filtering technology employed in the typical pub/sub model has some drawbacks such as useless connection and wasted queue space. In this paper we propose an efficient and dynamic location- based event service solving these problems. It is achieved by employing location monitor which dynamically manages the event channel. Performance evaluation shows that the proposed scheme provides much higher performance than the existing scheme when the number of suppliers is larger than six.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129002090","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}

These are well known for their benefits like focus on quality, early business value delivery, higher morale of stakeholders, and the reduced cost/schedule. Also, they can support the earlier and quicker production of the code by dividing the product into small segments called iterations. However, there are on-going debates about their flexibility to accommodate changing requirements and whether the productivity and quality of the agile processes is satisfactory for the customers or not. Previously available studies have mostly focused on comparing XP(eXtreme Programming) with some other agile methodologies, rather than comparing it with traditional plan-driven software development methodologies. In this paper, we identify the XP phases and practices, how they ensure product quality, and map XP phases against the Spiral model phases to prove that XP has built-in QA (quality assurance) practices in its life cycle, in addition to its focus on productivity. A case study is also included to empirically investigate quality of the product developed using XP with comparison to the product developed using Spiral model.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121034059","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 can form decision regions with arbitrary shapes if activation functions of hidden nodes are chosen properly. However, in data collection and analysis there often exist outliers which affect the performance of classification. In order to enhance the classification performance of the SLFNs, it is important to detect and eliminate these outliers. In this paper, we propose an approach for outlier reduction based on distribution of every feature, in which scores are assigned to patterns. Patterns detected as outliers based on these scores will be eliminated from data set. One interesting observation is that, our approach can obtain high accuracy with fast learning speed if the training set exist patterns deviating from mainstream of the remaining of the data set.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122504632","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}

But there are many problems in traditional single sink sensor networks. The energy of the sensors near the sink or on the critical paths consumes too fast causing unbalanced energy consumption. The routing algorithms mainly focus on the nearest path or minimum hops. The invalidation of the single sink node causes the breakdown of the whole sensor network. In this paper, through the analysis of the disadvantages of single-sink sensor networks, we propose the system architecture of multi-sink sensor networks and new routing algorithms ELBR (Energy Level Based Routing) and PBR (Primary Based Routing) in multi-sink sensor networks. Experiment results show ELBR and PBR have better performances than traditional methods and balance the energy consumption in sensor networks.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"94 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122629035","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 provide high resilience against failures, OTNs must have an ability to maintain an acceptable level of service during network failures. Fast and resource optimized light- path restoration strategies are urgent requirements for the near future OTN with a generalized multi-protocol label switching (GMPLS) control plane. Our objective in this paper is to presents a multi-layer recovery scheme that guarantees fast and efficient recovery of lightpaths in ASON/GMPLS networks.

This paper addresses the vehicle routing problem occurred in a refuse collection area, Seoul, South Korea. The vehicle routing problem considered in this case study is the problem of determining the vehicle routes that satisfy the demand at each collection point while satisfying the vehicle capacity for the objective of minimizing the total distance traveled. Unlike the ordinary deterministic version of the problem, we consider the problem with stochastic demand at each collection point. Therefore, the vehicle capacity may be violated at random. Two types of solution algorithms, deterministic and stochastic ones, are suggested. To show the performances of the algorithms, simulation experiments were done on the case data, and the results show that our algorithms significantly improve the conventional method.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133461698","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 method is well established for triatomic molecules, and recently it has been applied to biomolecules such as alanine dipeptide.
