Big data includes huge volume, high velocity, and extensible variety of data. The Big data is in the form of Structured data (Ex: Relational data), unstructured data (Ex: Text, PDF, Word) and Semi Structured data (Ex: XML data). It is really a tedious task to process such data through a traditional database server. Google solved this problem using an algorithm called Map Reduce, used in the technology Hadoop. In this paper we discuss some security issues in Hadoop associated with Big data. Big data applications are very much useful to Organizations, all type of Companies may be small or large scale companies and to the Industries etc.","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85430925","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 is observed that SMEs are picking up the most from cloud computing, as it is a complex and costlier task to set-up and run ICT (Information and Communication Technology) in a traditional way. But, many SMEs generally do not see all the information security risks involved in cloud computing and have to compromise on their data at the end. This paper provides a guidance for SMEs of India about the security aspects of cloud computing. It facilitates the decision making process through the proposal of a taxonomy which highlights the security factors to be considered when evaluating the cloud as a potential solution.

These earthquakes have been ranked among the most significant ones due to their effects. The earthquakes were felt in many settlements. Nepal earthquakes caused considerable damage to buildings and to public facilities. The first damage assessment of constructions after earthquake has importance in order to prevent loss of life and property in coming earthquakes. In this study the effects of earthquakes on constructions in Nepal have been evaluated. The damages to reinforced-concrete (RC) and masonry structures after earthquake are evaluated and recommendations made in Nepal which is seismically active. The goal of this paper is to introduce major reasons for structural damages after earthquakes. The observed damages overlap with typical earthquake damages. It has been observed that the negative features of constructions have caused an increase in damage extent. The careless selection of the design and construction of structural systems has increased the damage extent.","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76837752","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}

Association rule mining is an important topic in data mining field. Association rule mining finds collections of data attributes that are statistically related to the data available. Apriori algorithm generates all significant association rules between items in the database. Besides, ACO algorithms are probabilistic techniques for solving computational problems that are based in finding as good as possible paths through graphs by imitating the ants’ search for food. The use of such techniques has been very successful for several problems. The collaborative use of ACO and DM (the use of ACO algorithms for DM tasks) is a very promising direction. In this paper, based on association rule mining and Apriori algorithm, an improved Ant Colony algorithm is proposed to solve the Frequent Pattern Mining problem. Ant colony algorithm is employed as evolutionary algorithm to optimize the obtained set of association rules produced using Apriori algorithm. The results and comparison of the method is shown at the end of the paper. --------------------------------------------------------------------------------------------------------------------------------------Date of Submission: 11-07-2017 Date of acceptance: 22-07-2017 --------------------------------------------------------------------------------------------------------------------------------------","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78270168","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 2010 alone, HIV/AIDS killed 1.8 million people, 1.2 million of whom were living in sub-Saharan Africa. In Ethiopia,HIV/AIDS is one of the key challenges for the overall development of Ethiopia, as it has led to a seven-year decrease in life expectancy and a greatly reduced workforce. Even if there are a number of voluntarily counseling and testing centers that work on HIV/AIDS prevention located in several cities of the country, they didn’t change and solve the problem related with HIV/AIDS. In addition in most of Countries counseling and Testing centers ,the data collected is simply put together and maximum used for statics purpose rather than analyzing to discover relevant and interesting previously unknown data characteristics,relationships,dependencies etc . The main objective of this study was pattern discovery and generating interesting hidden association rules from data which is taken from Marie stopes Gondar branch clinic. The contribution of this Study is by analyzing customer’s data that did HIV/AIDS test on the clinic, to identify which customer is more vulnerable to HIV/AIDS. It helps counselors in VCT centers in predicting some hidden but interesting relationships among the attributes they use during the course of counseling. For doing this, methodology such as data collection and tool selection was used. After data was collected, the main data preprocessing tasks are applied on data sets to clean data and to make it ready for experiment purpose. Out of 1992 instances of original data 1861 was made ready for the experiment. Weka3.4. tool is used for experiment and the well known association rule mining algorithm Apriori was used to extract those interesting rules from data. In order to get those interesting rules three basic experiment was conducted .Experiment I was conducted by using the whole data set. Experiment II was conducted by considering only those positive classes. Experiment III was done by only considering those positive classes but with the absence of positive class attribute. One of the result of experiments showed that customers that donot use condom during sexual intercourse and non employed person are vulnerable to HIV/AIDS.","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75116173","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}

Inter-agent communication is the most integral part of any MAS. The problem of impreciseness and obscurity in agent communication has been swelled with increasing complexity of MAS and deepened with the rise of heterogeneity and diversity in varied platforms of data storage. Another technology with parallel growth is the semantic theory, significantly contributing in providing meaning to expressions thereby reducing ambiguity. The authors here provide two layers of verification of messages. At first, a vocabulary of terms used in messages is constructed with the help of an ontology in OWL to diminish vagueness. Then at a higher level business organization rules contribute to another ontology defining the policies that orchestrate the MAS establishing the domain of organization. The O-MaSE is used as MAS design methodology. In this paper, extension to O-MaSE is provided through dual verification system.","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90884862","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}
