The effective use of UAVs in agriculture, especially crop-spraying drones, requires a more extended flight range. Batteries currently limit a drone’s flight time since purely electric drones tend to consume more electrical energy with their higher payload capacity. For this reason, the present project proposes the improvement of an Agras MG-1P octocopter drone batteries’ load supply through a load system consisting of a double-cylinder VVRC RCGF 70cc combustion engine and a KDE10218XF-105 brushless motor as a generator. The brushless motor operates as a generator since it weighs less than an alternator or generator. The weight is significant, and the octocopter can stay longer in the air. This project aims to increase the Agra MG-1P Octocopter UAVs flight time by more than two hours, as well as its payload, having a 9 l variable load of fumigant and a 4.4 kg load of added components,...

After conducting the historical review of marketing and especially experiential marketing, which considers various types of experiences such as sensations, feelings, thoughts, actions and relationships, seeking in the consumer greater satisfaction and therefore greater effectiveness in the action of marketing, as well as establishing the state of the art of immersive technologies and their applications in marketing, the authors propose a software architecture model for hotel services, which includes the description of hardware and software elements for development and implementation. The model would make it possible to bring customers closer to experiences that are very close to reality,based on their profiles and characteristics, previously treated by a recommendation module included in the proposal, a fact that supports the decision of purchase, with a high degree of adaptation to thei...

Interactive whiteboards are an educational tool widely adopted as part of the integration of Information and Communication Technologies (ICT) and cost reduction. This technology becomes more effective when teachers know and apply interactive teaching methods that can improve the results of the teaching-learning process. This research presents a training model for primary and high school teachers in Yanaquihua, Condesuyos, Arequipa. The proposed training model generated good results: teachers improved their interactive content-making skills by 29 percent. Also, 50 percent of the interactive content created by teachers is considered satisfactory quality. Only 11 percent of teachers needed to dedicate more effort to achieve the objectives. This document reports the importance, the limitations, and the results of applying the proposed training model to improve the performance and effectivene...

La utilización de recursos virtuales para facilitar el aprendizaje de habilidades y técnicas de investigación en estudiantes de pregrado es fundamental para su formación profesional. Por esa razón, el objetivo del artículo es determinar la influencia de las tutorías virtuales en la redacción de informes de investigación en estudiantes de carreras de negocios en la modalidad de educación virtual. El artículo describe un diseño de investigación descriptivo longitudinal, analizando los resultados obtenidos por los estudiantes en la redacción de sus informes de investigación durante los años 2016, 2017, 2018 y 2019. Se evalúa cuantitativamente por los logros de aprendizaje de cada criterio definido y cualitativamente en función del juicio de experto de 8 docentes con experiencia en el desarrollo de asignaturas de investigación en pre y post grado. Los resultados muestran u...

Solar thermoelectric cooling technology applied to transport ofA thermoelectric cooling system supplied by photovoltaic solar energy was built and evaluated with different thermal loads. The thermoelectric cooling module consumes 70 W, it is supplied by a photovoltaic system of 90 W and 40 Ah battery. The voltage and electrical current in each component (panels, battery, and electric charge) has been measured. The tests were performed with different thermal loads placed in glass containers used for vaccines. To analyze the cooling and preservation process, the experiments were started at room temperature. The results show that the thermoelectric cooling system works for small thermal loads, and it could be applied to transport vaccines in isolated areas where people carry medicines in small containers that do not maintain the temperature necessary for the conservation of vaccines. vaccin...

A reliable methodology for the dimensioning of photovoltaic systems is presented in this paper. This method generates technical-financial variables that aid in the choice of the most adequate photovoltaic power system for each project. The techniques that are usually used determine the size of PV power plants considering the monthly average of the solar energy potential of the month with the lowest solar radiation and the electricity to be supplied to satisfy the demand. These conventional techniques generate an uncertainty of at least 40 %, mainly due to the daily dispersion of the solar energy availability and of the electric load. The proposed methodology takes into account a region’s own photovoltaic energy potential and the detailed characteristics of the electric load, matching both with different PV power plants sizes, and analyzing the whole during a time period that guarantees...

El presente proyecto de innovación intenta impulsar la promoción y difusión de las actividades de vinificación a través de la introducción de la tecnología de "estimulación sensorial dinámica" (DSS). El primer objetivo de este trabajo es describir la implementación de un salón interactivo que utiliza esta tecnología para mostrar algunas características organolépticas del pisco y el vino. La tecnología DSS está equipada con equipos sincronizados que brindan a los visitantes una experiencia sensorial integral que consiste en estimulación climática, similar a la del viñedo (principalmente en cuanto a temperatura y humedad relativa); estimulación olfativa con diferentes aromas a través de un aerosol controlado (simulando la recolección de olores asociados con los procesos de fermentación y destilación); estimulación científico-gustativa (degustación técnica); y es...

In the present experimental study, a photovoltaic (PV)-powered system in continuous current (4 kW) for the pumping of water in an isolated, rural agricultural zone in Arequipa—Peru was analyzed. A meteorological station was installed in the studied zone, measuring solar radiation, temperature, relative humidity, and wind speed. The electrical and hydraulic parameters of the solar-pumping system (i.e., electric current, voltage, mass flow, and hydraulic pressure) were measured in order to evaluate the efficiency of the energy transformation processes. The results indicate that, during the year of 2017, the PV pumping system in direct current (DC) functions from 07 h 30 min to 15 h 30 min, during an average of 8 h a day. The PV array, hydraulic, and global efficiencies were evaluated. This allows for the interpretation of efficiency independent of solar irradiance. The efficiency of the ...
