We identified seven relevant value dimensions in a first case study and in a second case study we investigated the relation between the seven different value dimensions. Afterwards we define an optimal iteration based on our value definition for multiple non-cross-functional teams and show that this problem is a NP-hard problem.","PeriodicalId":120340,"journal":{"name":"Research in Adaptive and Convergent Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126038063","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}

Novice web programmers, with little or no secure programming skills, unknowingly develop web applications ripe with security vulnerabilities, thus compromising the integrity of the application. As a result, a number of static analysis security tools have been developed to flag potential security vulnerabilities. Yet, these tools are difficult to use, divorced from the software integrated development environments (IDE) and remain unknown to novice developers. This paper contributes an Eclipse plugin that enables static analysis of PHP source code using existing tools directly within a common IDE to enable novice developers to build more secure web applications. We make two claims for the extension of SSVChecker. First, it seamlessly embeds into a common IDE making it easy/familiar to use for novice developers. Second, it provides functionality leveraging multiple tools to reduce reported false positives and better focus novice developers on potential security vulnerabilities. To demonstrate these claims, we use SSVChecker on a popular, open source, PHP-based web application with known security vulnerabilities.","PeriodicalId":120340,"journal":{"name":"Research in Adaptive and Convergent Systems","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126126669","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}

Human lives in the world where web documents have a great potential and the amount of valuable information has been consistently growing over the year. There is a problem that finding relevant web documents corresponding to what users want is more difficult due to the huge amount of web size. For this reason, there have been many researchers overcome this problem. The most important thing is document classification. All documents are composed of numerous words. Many classification methods have been extracted keywords from documents and then analyzed keywords pattern or frequency. In this paper, we propose Category Term Weight (CTW) using keywords from documents in order to enhance performance in document classification. CTW combines keywords frequency with semantic information. The frequency and semantic information have a great potential to find similarities between documents. That is why we calculates CTW from collection of training documents. After this step, CTW from unknown document and CTW in previous Category Term Database will be applied by designed Markov Logic Networks Model. Our designed MLNs Model and existing Naive-bayse Model will be compared by applied CTW. The experimental results shows the improvement of precision compare with the existing model.","PeriodicalId":120340,"journal":{"name":"Research in Adaptive and Convergent Systems","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130445648","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}

Such a developing trend would prolong the initialization time of these embedded computing systems. Hibernation (or suspend-to-disk) that retains a computing system's state after power recycling is regarded as a solution to reduce the booting time of systems and applications to meet the requirement of user experiences. In contrast to the existing hibernation techniques that dump most of the memory pages to the secondary storage, we propose a classification-based prefetching scheme to improve the system performance on both of the hibernation and resuming with minimized I/O overheads by jointly considering the system/application behaviors and the usage patterns of memory pages. The proposed scheme was also implemented with the Linux kernel on an evaluation board to show the capability of the proposed scheme.","PeriodicalId":120340,"journal":{"name":"Research in Adaptive and Convergent Systems","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116948199","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}

For binaries, not many reliable birthmarks are developed. API sequences are known to be successful birthmarks, but dynamically extracted sequences are often too large and unnecessarily repetitive. In this paper, we propose a static approach to generate API sequences along major paths, which are analyzed from control flow graphs of binaries. Since our API sequences are extracted along the most plausible paths of the binary codes, they can represent actual API sequences from executing binaries, but in a more concise form. In addition, as it is a static analysis, we can apply to partial binary objects, which cannot be executed on their own. Our similarity measures use the Smith-Waterman algorithm that is one of the popular sequence alignment algorithms for DNA sequence analysis. We evaluate our static path-based API sequence with multiple versions of five applications. In our experiment, our method reports a quite reliable similarity result for binary codes.","PeriodicalId":120340,"journal":{"name":"Research in Adaptive and Convergent Systems","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126505335","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}

In this paper, we address the issue of quantifying uncertainties on the energy demand side. Specifically, we first develop approaches using statistical modeling analysis to derive a statistical distribution of energy usage. We then utilize machine learning based approaches such as the Support Vector Machines (SVM) and neural networks to conduct accurate forecasting on energy usage. We perform extensive experiments of our proposed approaches using a real-world meter reading data set. Our experimental data shows that the statistical distribution of meter reading data can be largely approximated with a Gaussian distribution and the two SVM-based machine learning approaches achieve a high accuracy of forecasting energy usage.","PeriodicalId":120340,"journal":{"name":"Research in Adaptive and Convergent Systems","volume":"4 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132273506","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}
