The design of a control system in certain processes in the industry is the main problem for engineers. Since the input and output data of a certain process are obtained, we can know the response of the system, the same that allows us to study a model prototype and using the theory of nonlinear control the limit cycles are predicted, we can propose a function descriptive whose parameters will be necessary to implement the Neurocontroller that will be trained with the Back propagation algorithm. In our case, we address the design and implementation of a Neurocontroller in the LabVIEW graphical program environment under the supervision of the Simulation Toolkit. Our application is the control of a prototype physical system whose model can represent first and second order systems. The model of the process dynamics was obtained experimentally, for which the identification of parameters was ap...

Discrete-time survival models are discussed and applied to the study of which factors are associated with student dropouts at a private university in Lima, Per_u. We studied the characteristics of 26; 790 incoming students enrolled between 2004 and 2012 in all the under-graduate programs at the University. The analysis include the estimation of the survival and hazard functions using the Kaplan-Meier method and the _tting of parametric models using the Cox proportional hazards regression and the Logistic regression for survival analysis, this last one, in order to include time varying variables as predictors. During the period of analysis, the cumulative probability of remain at the University after _ve years was 73.7% [95% CI: 73.1% - 74.4%]. In any period the hazard is greater than 4.4% and this highest value is reached in the 3rd semester. In a multivariate analysis, we found that aca...

Predicting the exact behavior of elements under stress has been and continues to be a matter of study in various professional branches, with the finite element method (FEM) being an alternative solution to this premise over a long period of time. However, in contrast to its relevance, this methodology presents some flaws in its learning, which often creates a false complexity of application in students willing to understand this methodology. Due to the complexity presented by the theoretical-applicative learning of the MEF, the present research aims to provide a learning strategy that is easy to understand, directly relating the theoretical and applicative part of the method. An investigation was carried out on various publications of prominent authors in the methodology, compiling their various forms of teaching. From this research, the possible elements that may hinder the learning of ...

We present a scheme of eHealth based on teleconsults aimed to reduce unexpected events and complications in type-2 diabetes mellitus (DM-II). To this end, this study has considered the history of glucose tests taken as input inside a predictive mathematical scheme based on probabilities. The resulting output goes to a real-time monitoring system in order to detect and update those cases where patients would require of rapid assistance. The simulations have shown that the opportune intervention of teleconsults might be effective in the sense of monitoring diet and drug-based treatment by employing simple mobile phones and minimal software applications. For example, the case of a critic patient with a rapid increasing of glucose above 200 mg/dL, the opportune intervention of teleconsults might reduce these values by a 50% during a time of 20±2 days. It can also be traduced as the improvem...

It's well known that the duration of the engineering programs in Latin American countries like Peru are of order of 5 years, roughly. Commonly, the target of the fifth year of program is to carry out activities of thesis and capstone projects. Clearly these activities would demand that the student can exhibit skills and a certain level of maturity which might be crucial for a successful completion of the projects. However, the expected performance of the students might be correlated to the educational features of the institution (university, technological institute, etc) to some extent. In this manner, in this paper we try to measure the quality of education (QoE) of a Peruvian engineering program through the application of a mathematical methodology based on the individual score of students along the time where the projects take place. Furthermore, the error of the model is interpreted ...

The demand for the food industry has maintained sustained growth in recent years. In Peru, as a consequence of the high competitiveness in the food sector, it has reflected a considerable contribution to the manufacturing GDP with 20% and 2.6% to the national GDP (Gross domestic product). However, the high demands of the market are not satisfied due to problems such as the availability of machinery, mainly due to high programming times, and high frequency of machine stoppages, among others. These problems generate large monetary losses and a bad image in front of large potential customers. Thus, this research work, taking as a case study an SME (Small and Medium-Sized companies) of the food sector, seeks to provide the application of the tools of the LM (Lean Manufacturing) and TPM (Total Productive Maintenance) philosophies, to reduce the high setup times and the high frequency of machi...

For a long time, J2EE has been the dominating framework for the development of business applications. This fact resulted in a rich ecosystem of tools, manuals, tutorials, etc. that explain different implementation alternatives or peculiarities. The incursion of .NET Framework in the business environment has generated a strong demand of application implementation under this architecture. However, the quantity and quality of documents available significantly differs from its main alternative (J2EE). This documentation gap is especially visible and worrying when the objective is to teach the concepts of Framework, from a teacher’s point of view, to the future graduates of the Information Systems Engineering program. This paper describes the teaching approach used in order to achieve the goal of having the students become familiar with this alternative framework and the usual model practi...

Genealogical and productive records are the most important pillars within genetic and genomic improvement programs, where the diversity of data that can be collected must be systematized and related, to carry out an adequate statistical analysis considering all the factors that influence the variables. On the other hand, the current proposals do not contemplate the total registration of the population, both genealogical and productive records. Moreover, there is no software that allows systematizing, ordering and providing objective and measurable information in an orderly manner within the management of domestic camelids. For this reason, the construction of a computer application was proposed allowing the collection of genealogical and productive records of the entire population of both alpacas and llamas within the herds. As a result, the computer application called "Pacokipu" and "Ll...

The task of elaborating accurate test suites for program testing can be an extensive computational work. Mutation testing is not immune to the problem of being a computational and time-consuming task so that it has found relief in the use of heuristic techniques. The use of Genetic Algorithms in mutation testing has proved to be useful for probing test suites, but it has mainly been enclosed only in the field of imperative programming paradigms. Therefore, we decided to test the feasibility of using Genetic Algorithms for performing mutation testing in functional programming environments. We tested our proposal by making a graph representations of four different functional programs and applied a Genetic Algorithm to generate a population of mutant programs. We found that it is possible to obtain a set of mutants that could find flaws in test suites in functional programming languages. Ad...
