This document will present an educational videogame called Ashy.alRescate () that aims to teach the subject of object-oriented programming (OOP) in Java programming language through the mixture of a baseline story of the videogame with the implementation of programming code. The student programs the classes of the characters, their methods, attributes among others, for providing functionality to the characters. The results tested on university students show that there are improvements either in learners with only previous knowledge in C programming and in learners which have pursued an OOP course.

Effective learning and achieving universal primary education has been one of the United Nations focuses on recent years. To this, we must consider the effect of lack of interest in reading that exists on the part of students at the basic level [1]. The following work shows a proposal of a tool so that students of basic education can learn myths through ROLE type games. 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.
有效学习和普及初等教育是联合国近年来关注的重点之一。对此,我们必须考虑到在基础阶段存在的学生对阅读缺乏兴趣的影响[1]。下面的工作展示了一个工具的建议,使基础教育的学生可以通过角色类型的游戏来学习神话。还公布了测试前测试的设计、选定的案例研究以及在评估活动开展后通过测试在学习水平上获得的结果。所获得的结果表明,学生在学习上获得了实质性的改善,这意味着它在其他领域的应用是有希望的。

This paper describes an implementation of a FEM acoustic application on a GPU using C/C++ and CUDA libraries. 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.
本文介绍了利用C/ c++和CUDA库在GPU上实现有限元声学应用程序。声学模型是一个具有封闭流体和矩形面的刚壁腔。在一般特征值问题中,利用惯性矩阵和刚度矩阵计算固有频率。这些矩阵是对称的,密集的,并且从网格中的划分数量中以立方的比例增长。该模型采用cuSOLVER库实现,解决特征值问题。为了比较GPU的实现结果,对CPU进行了MATLAB实现。基于gpu的雅可比方法在单精度下给出了最好的结果,该方法比MATLAB实现速度快5倍。与模型的精确解相比,GPU双精度分治法是最精确的实现方法。最后,利用特征向量绘制腔内声压分布图。

Debugging is the task of locating and fixing defects in a program. 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.
调试是在程序中定位和修复缺陷的任务。基于频谱的故障定位(SFL)由于其相对较低的执行成本,是一种很有前途的调试技术。SFL通过对更可能包含错误的行、方法、类和包进行排序来确定最可疑的程序元素。我们比较了两种使用不同隐喻的SFL工具。Jaguar使用文本隐喻,而CodeForest使用三维隐喻。本文介绍了对76名学生使用这两种工具进行评估的结果。评估了它们在故障定位过程中的有效性和效率。通过工具将开发人员引导到错误方法或线路的能力以及定位错误所花费的时间,分别评估了有效性和效率。结果表明,Jaguar比CodeForest更有效。然而,这两种工具在效率上并没有区别。

There are many factors present in the current problems found in the teaching-learning of programming. 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.
目前程序设计教学中存在的问题是多方面的。这是一个世界性的情况,影响着我们学校,也影响着这个国家的其他学校。在本文中,我们关注的是集成开发环境在课堂上使用的效果,特别是在第一年的编程课程中。更具体地说,本文展示了在Code::Blocks IDE上进行启发式评估的设计、应用和结果。Code::Blocks IDE目前用于C编程教学,与其说是教学工具,不如说是一个专业工具。基于为学习环境量身定制的最先进的启发式,我们发现了60个问题,其中Code::Blocks被认为是威胁和非激励,从而潜在地阻碍了学生的学习过程。我们认为这项工作是为我们的编程课程开发以学生为中心的编程环境的一步。

The automatic generation of video description is currently a topic of interest in computer vision due to applications such as web indexation, video description for people with visual disabilities, among others. In this work we present a Neural Network architecture Encoder-Decoder. First, a Convolutional Neural Network 3D extracts the features of the input video. Then, an Long Short-Term Memory decodes the vector to automatically generate the description of the video. To perform the training and testing we use the Microsoft Video Description Corpus data set (MSVD). Evaluate the performance of our system using the challenge of COCO Image Captioning Challenge. We obtain as results 0.3984, 0.2941 and 0.5052 for the BLEU, METEOR and CIDEr metrics respectively. Competitive results compared with certificates in the bibliography.

Currently, the detection of students who may drop out from an academic program is a relevant issue for universities, so there are efforts to examine the variables that determine students' drop out. 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.
目前,对于大学来说,检测可能从学术课程退学的学生是一个相关问题,因此有人努力检查决定学生退学的变量。辍学有不同的定义,然而,所有的研究都一致认为,一个学生要想退出一门课程,必须结合一些变量。本文对目前基于逻辑回归技术的universsidad del Bío-Bío (UBB)退学模型的绩效指标进行了比较,并与基于决策树的新模型进行了比较。该模型通过数据挖掘方法得到,并通过SAP预测分析工具实现。为了训练、验证和应用模型,使用了来自UBB数据库的真实数据。对比表明,该模型预测学生辍学的准确率为86%,精密度为97%,错误率为14%,优于目前基于逻辑回归的模型所提供的指标。随后,考虑其他变量对得到的预测模型进行优化,进一步提高了预测指标。高等教育机构应该考虑到最能解释学生辍学现象的变量,以提高学生的保留率。

Computer science tecniques, methodologies, and approaches, are directly applied to improve other enginnering disciplines. Construction is no exception, where software and data analysis are used to improve the processes of control and monitoring of construction projects. Most of the analysis are based on a key-value perspective analysis of the data. However, an emerging Process Mining discipline has proven to be able to capture a different process perspective. This interdisciplinary work is a step on this direction, proposing the Constraint Bag Process Model (CBPM), a novel use of Process Mining for answering process-oriented questions on construction projects.

Extending the CMHD Compact Data Structure to Compute Aggregations over Data Warehouses 扩展CMHD紧凑数据结构以计算数据仓库上的聚合
Pub Date : 2018-11-01 DOI: 10.1109/SCCC.2018.8705230

Compact data structures are data structures that allow compacting data without losing the ability of querying them in their compact form. 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.
紧凑数据结构是一种数据结构,它允许压缩数据而不会失去以紧凑形式查询数据的能力。我们提出了扩展紧凑数据结构CMHD(多层域多维数据的紧凑表示)功能的算法,它允许在多维矩阵上使用SUM函数计算聚合查询。我们实现了其余的聚合函数,即函数MIN, MAX, COUNT和AVG。我们在数据仓库(dw)上使用chd, dw是组织起来支持决策过程的数据集合。数据仓库中查询处理效率的提高是一个非常重要的问题。因此,在这个方向上作出了各种努力,例如视图的具体化、索引的使用等等。通过使用合成数据对数据仓库进行实验,我们发现,通过使用数据仓库的紧凑表示,我们可以在处理聚合查询时获得更好的性能。

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.
