There are several motives for this. Some situations are the generation of these bases from texts, another is the amount of open data generated from information systems. Their growth results in a large volume of information available. This fact brings the possibility of large-scale use in question-and-answer systems. Which have a general function that is based on a structure of information to generate phrases and to conference of produced answers. From literature studies, we foresee an opportunity of bigger use, in several applications. It is possible to generate natural language phrases from linked open databases, in Portuguese. In addition, we identified challenges to effective applicate linked open data resources for this purpose effectively. In this way, this work aims to see which aspects of the structure of open linked databases could be used as support in generating natural language questions.","PeriodicalId":379986,"journal":{"name":"2018 XLIV Latin American Computer Conference (CLEI)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114968927","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 was developed for the Hololens device, following the Suzuki method for instructing the first lesson of the instrument. This prototype utilizes a 2D marker, using the video game engine Unity3D. The prototype was tested comparing the learning experience it offered to the one of a non-immersive learning methodology. As a result, the study did not show any considerable difference between the two methods, but it revealed learners' acceptance towards the augmented reality teaching tool, and it showed information which could be considered to define the research approach for the following stages of the project. It is still necessary to implement several design and functionality improvements to the initial prototype for a new process iteration.","PeriodicalId":379986,"journal":{"name":"2018 XLIV Latin American Computer Conference (CLEI)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115156809","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 mutation of the code is carried out through a process of model transformations that starts with a transformation of a JAVA program to a representation of it in XMI, which satisfies the requirements of the JAVA metamodel. Later, mutation rules are applied to the model by means of a transformation, model by model, to generate a mutated version of the original program. Finally, JAVA code mutated again through a transformation, model to text, defined with MOF2Text. This last version is the one used to experiment with the different test cases. The main contribution of this work is the proposal of a mutation mechanism of JAVA programs that makes use of existing standards and tools in the context of model-driven development.","PeriodicalId":379986,"journal":{"name":"2018 XLIV Latin American Computer Conference (CLEI)","volume":"809 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123290288","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}

However, the structure of the systematic review and the catalog under development can be extended to other areas. With a traceable structure among the key elements of the catalog (play practices, levels of knowledge and contents), we try to present a practical reference material for developers of educational games or even for teachers who want to apply recreational activities in the classroom. The catalog under construction is available on a wiki in order to enable it to grow collaboratively.

Most use the C language as development tool, but the approach applies more effort in describing the language's peculiarities than exploiting the practical applications in engineering endeavors. The contributed programming techniques are born from the experience of teaching Functional Programming, embodied in headers that enhance depth and rigorousness in the development of high quality code: (i) Functional emphasis from the beginning; (ii) Formal Specifications with exception generation; (iii) Early focus in recursion, particularly tail recursion; (iv) Development of Abstract Data Types using C's opaque types; (v) Incorporation of First Order and Higher Order Functions; (vi) Efficient dynamic memory management using a \"garbage collector\"; (vii) Using and Integrated Developed Environment (IDE) with embedded debugger.

With the technological advance, the means used to acquire these sets, such as Computed Tomography or Magnetic Resonance Imaging, underwent improvements that resulted in a significant increase of the amount of information collected per sample, making it necessary to develop techniques to generate the visualization of this large quantity of information. The research presents in this paper has the purpose to develop a three-dimensional visualization tool to represent in real time volumetric data with the size of hundreds of megabytes. This tool is based on the ray casting algorithm using graphical acceleration features. To achieve this goal, a methodology was used that involved dividing the volume of data into smaller parts, compatible with the memory limitation of the video hardware. Then the data is used to compose a high quality final image representing the information contained in the volume. In order to evaluate and validate this methodology, comparative tests are performed between the standard rendering procedure and the procedure used in this research.","PeriodicalId":379986,"journal":{"name":"2018 XLIV Latin American Computer Conference (CLEI)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127916277","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}
