It is well known that the exact evaluation of the PDF of a project completion time is an #p-complete problem. To mitigate the high computational effort associated to the PDF evaluation, we propose a method that discards, in each step of the method, those times that has a low probability associated. This allows to consider only those relevant time elements of the project. The discard procedure is made with the restriction that a pre-established maximum accumulated error is achieved. In this way the method arrives to a compromise between accuracy and speed. To the best of our knowledge, this is the first time that an approximation method with a bounded cumulated error to the PDF evaluation of a SAN is proposed.","PeriodicalId":432676,"journal":{"name":"2016 35th International Conference of the Chilean Computer Science Society (SCCC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115741610","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 the eco-Connectivism is planed the configuration, the stabilization and the unification of an ecology of knowledge, composed of emerging clusters of personal learning environments. For this, it uses association rules, which are dynamically adapted for the analysis of the connections that occur between apprentices, in a socialized context of learning. The multi-agent system provides an intelligent model of dynamic configuration of roles, with the objective of providing configuration, stabilization and unification of the ecology of eco-connectivist knowledge, using concepts inspired from the ecology, the data mining and the collaborative filtering. Adaptive capacities of personal learning environments are provided by recommendation agents, which reason about emerging clusters based on a model of ecological survival. This enables to characterize the ecological unification of knowledge between individuals.","PeriodicalId":432676,"journal":{"name":"2016 35th International Conference of the Chilean Computer Science Society (SCCC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115900914","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 results of applying a systematic mapping to identify the most software metrics cited and the most statistical techniques/models used to evaluate quality in OO software. As a result, we highlighted 79 papers related to the research question in a total of 8,231 papers published in scientific journals.

The right choice of a methodology to guide the various activities to be made throughout the project can ensure its success. In order to know what the current proposals for the development of mobile applications are, a systematic mapping study which covered studies between 2007 and 2015 has been conducted. From this mapping, several studies have been selected; their contributions have been analyzed from different edges: goals, strengths, weaknesses, results, recommended tools, among others. The study showed that, although there are several proposed methodologies, most do not fit the life cycle of mobile application development; thus, adaptations and mergers of existing methodologies have to be made.","PeriodicalId":432676,"journal":{"name":"2016 35th International Conference of the Chilean Computer Science Society (SCCC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121955022","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}

Method: For this, we conducted a systematic mapping. Results: We identified 27 studies. All of these studies have explored the use of information related to software architecture to support the testing activity. The identified approaches have covered the integration, unit, and regression phases. Moreover, functional and structural techniques were also considered. Conclusion: We observe that there is still a range of open research topics to be explored, in particular, development of new supporting tools also applied in the software industry, what could result in high-quality software systems.","PeriodicalId":432676,"journal":{"name":"2016 35th International Conference of the Chilean Computer Science Society (SCCC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126367945","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}

We propose to use social network analysis to investigate the relationship between a nonprofits social media activity and the growth patterns of its online audience. To pilot the approach, we conducted a case study on the social media accounts of a well-known Chilean nonprofit. Facebook data show that the number of nonprofits posts increased over time, users' “comments” increased somewhat slower (and the network morphed into a few large clusters), but users' “likes” increased at a much faster pace (and morphed into a single strongly connected network). Twitter data reveal that the number of tweets dropped over time, and the “re-tweets” decreased even faster (morphing into ever more isolated small clusters). This pilot study shows that morphological analysis of social networks can be fruitfully applied to identify the changing interaction among nonprofits and their audiences.","PeriodicalId":432676,"journal":{"name":"2016 35th International Conference of the Chilean Computer Science Society (SCCC)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117260104","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}
