Intelligent prototype for the collection of small urban solid waste

Wasting disposal systems are a crucial sector in society, improper management of solid urban waste (SUW) can be harmful to health and the environment. In the state of Campeche, Mexico, an average of 3528.32 KG of waste is collected by every person, around 227 people are hired for this activity. This means that the generation of waste exceeds the collecting capacity in the state. This work presents an intelligent prototype for the collecting of small SUW. To achieve this task, we designed and created a model based on different electronic components (Raspberry, sensors, camera, etc.), as well as we created and implemented a SUW collection algorithm for its autonomy. The design of the prototype consists of two metal structures and the electronic components are integrated into the Raspberry. The creation and implementation of the algorithm work with artificial.

Thermal analysis of a parabolic trough solar collector with synthetic oil as working fluid using a computational tool

This work describes the use of a computational tool to assess a previously built parabolic trough solar collector (PTC) that uses a working fluid in liquid state. This work is focused on the thermal analysis of a PTC collector considering two common used synthetic oils: Syltherm 800 and Therminol VP1. The designing characteristics of the commercial LS3 solar collector was selected and as solar resource, the solar irradiance that reaches Mexico City was used with twelve monthly average values along the year. The computational tool provides thermal and flow data for every synthetic oil and for every solar irradiance value used. The most important data computed is the mass flow, which is obtained through iterative processes until the necessary value is found, in order to satisfy the working fluid final temperature for the synthetic oil, once the optimum mass flow value is found, the collector thermal parameters are computed, such as: heat gain, heat losses, thermal efficiency, and the temperatures for the absorber and coating tubes. The computational tool can assess any PTC collector with any working fluid in liquid state, and the data obtained can be used to improve of modify the design of the collector for a better performance.

RLC circuits: Obtaining the current graph using a mobile application

In this document we simulate the response (current value for t≥0) for a series RLC circuit through the solution of a second order differential equation. A mobile application is developed for the Android Operating System that obtains the graph of this current using the ANDROID STUDIO development environment and the GRAPHVIEW library. With the choice of the mathematical expression that defines the voltage in the circuit and the values of the resistance, the inductance, capacitance, the initial current and the initial voltage in the capacitor or initial charge, this graph is obtained, which when compared with what is obtained using a CAS, no difference is perceived, which shows the validity of the results of the app. This application can help engineering students to understand in an easy and simple way the concepts related to this type of circuits, thus promoting the use of mobile devices in teaching-learning environments.
