Its applications include the defrosting, cooking and pasteurization of food, the disinfestation of fruits, and the production of biofuels, among others. The main advantage of electromagnetic processing methods is that the heating takes place in the entire volume of the biomass to be treated; in addition, it has great flexibility for its application in batch or continuous processing, resulting in faster and efficient processes. Although applications at microwave frequencies have recently received more attention than the radio frequency range, the latter has an important advantage: as the operating frequency is lower, the radiation penetration depth is greater, allowing more uniform heating and the possibility of processing larger volumes. This work presents the design, construction and electrical characterization of an electromagnetic heating system suitable biomass processing. From reflection coefficient measurements between 1MHz and 30MHz, an equivalent electrical model is developed and its parameters are determined. The operation of the system is described, with emphasis on the applicator.","PeriodicalId":70645,"journal":{"name":"高等工程教育研究","volume":"236 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78700097","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 company La Libertad S.R.L was taken as a case study, applying the use of the business intelligence tool as an effective and efficient solution. For this article, points in the design of the DataMart have been considered, such as the management and analysis in a strategic way in the operational part of the company's sales area based on the types of products with the highest valuation and / or sale. Currently in the company La Libertad S.R.L., in the sales area, it has a transactional system that performs processes such as the registration of categories, customers, districts, employees, orders, suppliers, stores. This system that goes hand in hand with the database is feasible for the company, however there is no form of visibility of complete movements for the manager of the sales area, either from the current year or from previous years, which is of important interest. for the planning of future projects, and in case of wanting to carry out a project, they must handle visible data to support the marketing and production area. The article aims to develop a DataMart as a business intelligence tool which is a decision support service for Peruvian hardware companies that need to plan their activities and in turn reduce the time it takes to generate reports .","PeriodicalId":70645,"journal":{"name":"高等工程教育研究","volume":"334 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72424062","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}

Currently, the program is working on the learning outcomes model following the guidelines of the ABET accreditation model, which requires the creation of capstone-type courses that seek the integration of the learning and skills acquired throughout the student’s training, when analysing the ABET requirements and the CDIO methodology, common elements were observed that could be applied in the Aircraft Design courses. The way of working and the integration strategy of the CDIO methodology and the capstone course has allowed the courses seen within the study plan not to become isolated themes, but rather to become tools for solving real problems under a project environment that allows the development of new skills such as teamwork, self-learning, design, and problem-solving as close as possible to reality. The results of the implementation strategy and the conclusions that have been observed throughout the implementation of this work modality are presented, which include the motivation of students to carry out different activities such as participating in national and international aircraft design competitions such as the DBF (Design, Build, and Flight) by the American Institute of Aeronautics and Astronautics (AIAA).","PeriodicalId":70645,"journal":{"name":"高等工程教育研究","volume":"601 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77342058","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}
