However, when this task is performed manually by humans, they are susceptible to the risks presented by the environment, whether it is difficult to access the affected area or the presence of venomous animals, such as snakes and hornets. Given this scenario, and following the development of Unmanned Aerial Vehicles (UAVs), there is a proposal to use them to automate this task. However, external factors, such as wind, can influence the movement of these vehicles and consequently the effectiveness in performing certain tasks. Thus, this work had as purpose the study about the influence of the wind under free falling objects, which, in the scenario of this work, are the glasses containing the natural enemies of a certain pest, and the proposition of a strategy to be taken by the aircraft, in order to ensure the effectiveness of the task at hand. During the tests performed in a simulated environment, it was observed that the mathematical modeling of the wind and the strategy taken by the aircraft at run time were able to achieve good results, allowing the cup to be deposited very close to the pre-defined location.","PeriodicalId":379986,"journal":{"name":"2018 XLIV Latin American Computer Conference (CLEI)","volume":"58 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":"126569835","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}

Considering this scenario, the objectives of this work are to discuss the ocurrency of alerts in intravenous systems and to contribute to the reduction of the emission of false alerts in electromedical equipments, in particular in infusion pumps. To this purpose, the developed proposal, called BIRB, explores the use of Bayesian Networks to minimize the occurrence of false alerts when occurs a change in the flow rate caused by occlusions in infusion pumps. The occlusion is the procedure with the highest index of false alerts in this type of equipment. The achivied results with the BIRB proposal are promising, reaching 85% of accuracy, based on data from actual infusion pumps.","PeriodicalId":379986,"journal":{"name":"2018 XLIV Latin American Computer Conference (CLEI)","volume":"24 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":"126870711","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}

Usually, these business rules are designed to process the input data and change the software's internal state match this event. As a consequence of such design, software usually does not have reliable means to keep memory from its past states unless specifically programmed to do so. Even when such capabilities are built into the system, they are often too detached from the system's rules to be useful or they are built only in particular points of the system selected as relevant. This article discusses Event Sourcing, a software architecture design that organizes software's classes in such a way to provide a native memory of its past states, enabling the system to even replay old computations at will. We also present a case study where this architecture is applied in the development of an ERP System. The architecture was particularly useful to the development team as it dramatically increased error traceability.","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":"115362364","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}

A total of 502 studies were identified, and finally 6 studies were selected and analyzed according to distinct aspects. Conference proceedings is the most common venue. There is a concentration of approaches published that comes from Asia and Europe. Disco tool is the most frequently used tool. Meanwhile, the process discovery being the most relevant process mining type used by researchers in this research area. There are two evaluation methods reported as being used: case study and running example, where Scrum is the most frequently methodology used.

However, in general, the elderly present difficulties in this interaction because, in addition to the physical limitations imposed by aging, many applications were not properly designed to consider such restrictions. This paper presents the results of a survey pointing out main difficulties that elderly people face when using mobile devices and proposes strategies to overcome these barriers. The research was carried out by applying questionnaires in the form of customized applications. Based on the answers, some alternatives were proposed to try to circumvent the reported difficulties and to make the elderly acquire autonomy and use their devices safely, efficiently, without frustration regardless of their physical limitations. In order to evaluate and validate the proposals, a framework was developed to make it easier for application developers to create interfaces that incorporate the proposed estrategies.","PeriodicalId":379986,"journal":{"name":"2018 XLIV Latin American Computer Conference (CLEI)","volume":"29 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":"132337839","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 Uruguay, computer courses are increasingly being integrated into curricular content, since learning to program seems to be part of the skills needed for today's people. However, programming in general is absent in mathematics teaching, contrary to the inherent relationship of both. In turn, according to 2015 data from the Educational Monitor of the National Administration of Public Education of Uruguay, Mathematics is the least approved subject of the basic secondary cycle. MateFun is a functional programming language, accessible from a web application, especially aimed to math functions learning. It is intended that through MateFun the learning of programming strengthens the appropriation of the concept of mathematical function, at the same through this project we seek to generate scientific evidence of the transfer or the contributions of programming learning to math. Preliminary data show that the adolescents who experimented with MateFun had similar learning to the control group in mathematical functions, but they also acquired basic knowledge of functional programming.","PeriodicalId":379986,"journal":{"name":"2018 XLIV Latin American Computer Conference (CLEI)","volume":"44 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132783099","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}

To test the genetic algorithm, a substation virtual environment was used where the dimensions and distances are reliable for a real environment. In order to do so, the map division strategy and the creation of individuals with variable sizes were applied.
