Diseño y construcción de un secador solar para el secado de madera de baja densidad

The purpose of this research was to demonstrate that the use of residual oil as a heat transport fluid and the use of rice husk as a thermal insulator is an efficient alternative for the greater use of solar energy. For this, a prototype of a solar dryer was designed and built consisting of a flat solar thermal concentrator and a parabolic cylindrical thermal concentrator (CCP), this was validated by drying Guazuma crinita, Mart. (White ball) and monitored by a contact hygrometer. Five tests were carried out, the first test was considered as a control, in which heat transport fluid and thermal insulators were not used, and in the following four tests two types of heat transport fluids were combined (residual motor oil and brine) and two types of thermal insulators (wood sawdust and rice husk), obtaining as a result that the most efficient test was number three, consisting of residual motor oil as heat transport fluid and rice husk as thermal insulator. With the most efficient test, the prototype was validated by drying low-density wood, reducing the humidity of the wood from 45.8% to 12.3% in ten sunny days.

Sistema de información geográfica para el registro de actos delictivos como soporte de las comisarías usando el API de ArcGis

Citizen insecurity is one of the biggest problems in the world, in search of a solution to address this problem, we found that a GIS is a tool worth evaluating for a possible solution. As an objective of this study, we seek to evaluate the feasibility of using a GIS to record criminal acts supported by police stations, for the development of this project we propose SCRUM as a development framework and for the methodology of data collection we will take articles, theses, newspapers and external statistics. Throughout some research, we will be able to make different comparisons about elements for our software, this goes from the effectiveness of using it to improve citizen security, the different perspectives that similar software can take (real time population, time period population, state entities), to the best way to get a better cost benefit for the development by evaluating the differences between the software. Finally, we were able to conclude that there is a high degree of effectiveness on the part of the GIS, in addition to the fact that it makes possible new methods of prevention for the improvement of citizen security.

Nuevas tendencias para la optimización de los procesos de Inteligencia de Negocios

Business Intelligence is becoming more and more relevant in companies, this is due to the fact that decision makers rely on it to perform the work itself. Based on this assertion, it is necessary to facilitate the BI process, reducing response times and increasing effectiveness and efficiency. This article shows different ways to perform Business Intelligence, from the origin, i.e. the extraction of data, to the last link of the process related to decision making. To this extent, new alternatives are presented that with the necessary study have shown that they go beyond what we now know as BI, allowing not only to make decisions but also to propose that these have an automated support, also allowing the data to be processed practically alone and to handle more real reports based on data from various sources. The objective of the study is to analyze the new trends for the development of processes related to business intelligence, for which a meticulous bibliographic review has been carried out by consulting scientific articles, books and scientific conferences. First, the description of terms and the staging of the information collected through the research, dedicated to the various innovative trends for the deployment of Business Intelligence, showing new definitions, architectures and trends that are currently being carried out, have been developed. Finally, SOA architecture proposals, open data acquisition, process automation and data warehouse reengineering would allow the optimization of business intelligence through their alternatives.
