The design of the pre-test tests, the selected case study and the result obtained at the learning level with a test after the development of the evaluative activity are also announced. The obtained results demonstrate a substantial improvement in the learning obtained by the students for which it means that its application in other areas is promising.","PeriodicalId":235495,"journal":{"name":"2018 37th International Conference of the Chilean Computer Science Society (SCCC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129499858","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 acoustic model is a rigid-walled cavity with enclosed fluid and rectangular faces. Natural frequencies were computed using inertia and stiffness matrices in a general eigenvalue problem. These matrices are symmetric, dense and grow in a cubic ratio from the number of divisions in the grid. The model was implemented using cuSOLVER libraries to solve the eigenvalue problem. The MATLAB implementation was performed for CPU in order to compare the results of GPU implementation. The GPU-based Jacobi method in single precision gives the best results, this method is five times faster than the MATLAB implementation. The divide and conquer method in double precision for GPU is the most accurate implementation when comparing with the exact solution of the model. Lastly, the sound pressure distribution in the cavity was graphed using eigenvectors.","PeriodicalId":235495,"journal":{"name":"2018 37th International Conference of the Chilean Computer Science Society (SCCC)","volume":"600 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123944345","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}

Spectrum-Based Fault Localization (SFL) is a promising debugging technique due to it is relative low execution cost. SFL pinpoints the most suspicious program elements by ranking lines, methods, classes and packages more likely to contain faults. We compare two SFL tools that utilize different metaphors. Jaguar uses a textual metaphor while CodeForest a three-dimensional one. The results of an evaluation with 76 students using both tools are presented. They were assessed regarding to the effectiveness and efficiency during fault localization. The effectiveness and efficiency were assessed, respectively, by the tool’s ability to direct the developer to the faulty method or line and the time spent to locate them. The results show that Jaguar is more effective than CodeForest. However, there is not difference between the tools for efficiency.","PeriodicalId":235495,"journal":{"name":"2018 37th International Conference of the Chilean Computer Science Society (SCCC)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130719341","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 is a world-wide situation that affects our school, as well as others in the country. In this paper we focus on the effects of the Integrated Development Environment used in the classroom, specifically for first-year programming courses. More concretely, the paper shows the design, application and results of an heuristic evaluation performed on the Code::Blocks IDE, currently used for teaching C programming, and which is more of a professional tool than a teaching instrument. Based on state-of-theart heuristics tailored for learning environments, we found 60 problems in which Code::Blocks is perceived as threaning and non-motivating, thus potentially hampering the learning process of our students. We conceive this work as a step towards the development of a student-focused programming environment for our programming courses.","PeriodicalId":235495,"journal":{"name":"2018 37th International Conference of the Chilean Computer Science Society (SCCC)","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129123669","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}

Drop out is defined in different ways, however, all the studies converge in that for a student to drop out a course of study, some variables must be combined. This study presents a comparison of performance indicators of the current drop out model of the Universidad del Bío-Bío (UBB), which is based on logistic regression technique and it is compared with a new model based on decision trees. The new model is obtained through data mining methodologies and it was implemented through the SAP Predictive Analytics tool. To train, validate, and apply the model, real data from the UBB databases were used. The comparison shows that the prediction of student´ drop out of the proposed model obtains an accuracy of 86%, a precision of 97% with an error rate of 14%, better indicators than the current values delivered by the model based on logistic regression. Subsequently, the prediction model obtained was optimized considering other variables, improving even more the prediction indicators. Higher education institutions should take into account the variables that explain the most the phenomenon of student´s drop out to improve the retention of their students.","PeriodicalId":235495,"journal":{"name":"2018 37th International Conference of the Chilean Computer Science Society (SCCC)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133624830","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 present algorithms to extend the functionality of the compact data structure CMHD (Compact representation of Multidimensional data on Hierarchical Domains), which allows the computation of aggregate queries with SUM function on multidimensional matrices. We implement the rest of aggregate functions, i.e., functions MIN , MAX , COUNT and AVG . We use the CMHD over Data Warehouses (DWs), that are collection of data organized to support the decision-making process. The improvement of efficiency of query processing in DWs is a very important issue. Therefore, various efforts have been made in that direction, such as materialization of views, use of indexes, among others. We show through experimentation over DWs with synthetic data, that by using a compact representation of DWs, we can achieve better performance in processing aggregate queries.","PeriodicalId":235495,"journal":{"name":"2018 37th International Conference of the Chilean Computer Science Society (SCCC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115469145","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}
