Through such maintenance activities, the internal structure of the software system becomes more complex. We believe that studying how the complexity has evolved is important for understanding the actual maintenance activities. In a previous experiment, we analyzed how code clones and use relations between application and framework components change through a longitudinal study of open source software. However, we performed our analysis over only one set of framework and application, so we would like to discuss how our findings generalize. In this paper, we replicate the previous experiment, targeting several open source projects. By comparing with the result of the past experiment, we will discuss about generalities of our findings. Moreover, we study the differences between the trends for both incoming and outgoing edges, how use relations increase and decrease through long term development, and how code clones are introduced in the software in the early period of the development. These analyses have a certain level of commonality for understanding actual developers' activities.","PeriodicalId":39465,"journal":{"name":"International Journal of Computer Science and Applications","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80396469","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}

Malicious and digital imaging (digital products) tamper detection is the subject of this article. In particular, we focus on a special type of digital forgery detection - copy attack campaign, in which part of the image is copied and pasted into the image and the cover features a large image of intentions another. In this paper, we investigate the dynamic forged copy detection problem, and describes a highly efficient and reliable detection method that based on image source ANN identification..

By processing the blob of sign boards, the meaningful features are extracted. Tracking moving targets is achieved by comparing the extracted features with training data. After classifying the sign boards the system will intimate to user in the form of alarms, sound waves.

When there are missing observations, some desirable design properties like orthogonality, rotatability and optimality can be adversely affected. Some attention has been given, in literature, to investigating the prediction capability of response surface designs; however, little or no effort has been devoted to investigating same for such designs when some observations are missing. This work therefore investigates the impact of a single missing observation of the various design points: factorial, axial and center points, on the estimation and predictive capability of Central Composite Designs (CCDs). It was observed that for each of the designs considered, precision of model parameter estimates and the design prediction properties were adversely affected by the missing observations and that the largest loss in precision of parameters corresponds to a missing factorial point.","PeriodicalId":39465,"journal":{"name":"International Journal of Computer Science and Applications","volume":"8 1","pages":"1-18"},"PeriodicalIF":0.0,"publicationDate":"2014-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91047384","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}

Some bad situations give stress and leads to different sufferings. One can’t avoid situation but can have awareness when body feel stress or any other emotion. It becomes easy for doctors whose patient is not in condition to speak. In that case person’s physiological parameters are measured to decide emotional status. While experiencing different emotion, there are also physiological changes taking place in the human body, like variations in the heart rate (ECG/HRV), skin conductance (GSR), breathing rate(BR), blood volume pulse(BVP),brain waves (EEG), temperature and muscle tension. These were some of the metrics to sense emotive coefficient. This research paper objective is to design and develop a portable, cost effective and low power embedded system that can predict different emotions by using Naive Bayes classifiers which are based on probability models that incorporate class conditional independence assumptions. Inputs to this system are various physiological signals and are extracted by using different sensors. Portable microcontroller used in this embedded system is MSP430F2013 to automatically monitor the level of stress in computer. This paper reports on the hardware and software instrumentation development and signal processing approach used to detect the stress level of a subject.To check the device's performance, few experiments were done in which 20 adults (ten women and ten men) who completed different tests requiring a certain degree of effort, such as showing facing intense interviews in office.","PeriodicalId":39465,"journal":{"name":"International Journal of Computer Science and Applications","volume":"1 1","pages":"19-31"},"PeriodicalIF":0.0,"publicationDate":"2014-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84561993","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}
