This technical project was intended to develop and implement a Comprehensive Risk Management Plan at M&M PLASTICOTOPAXI, located in the province of Cotopaxi, in order to establish the guidelines established by the National Risk and Emergency Management Service (SNGRE), a model comprising five phases: Phase I was focused on risk analysis and vulnerability identification, in which it refers to naturally sourced threats as volcanic eruptions, in this the MESERI method was used; Phase II contains...

Emergency management is based on human planning and organization through a plan that allows optimal use of the technical means envisaged, in order to minimize the possible human consequences and/or economic that may arise of the emergency situation. That is why the objective of the research was to develop and implement an Institutional Emergency Plan in the Tourist Complex La Moya of the G.A.D. municipal of the canton San Pedro de Pelileo. For this purpose, a qualitative study was carried out...

The main objective of this research work was to develop and implement an Integral Risk Management Plan (PIGR) for the main building, hotel theater, municipal theater and tourism belonging to the Decentralized Autonomous Government of the canton Guano, in order to safeguard life, as well as the physical integrity of the people who work and visit the facilities under study, at the time of a natural or anthropic event. The PYGM has five phases which relate to risk analysis, risk reduction guidel...

The objective of this study was to analyze and characterize the mechanisms of failure due to torsion, traction and impact in the steel of hydraulic turbines (ASTM A743 CA-6NM) in order to determine the type of fracture that the material presents, due to the CIRT wear and Failure Analysis Laboratory does not have a record of standard photographs of these mechanisms Verification of ASTM A743 CA-6NM steel was carried out by spectrometric, metallographic and hardness tests. Specimens were machine...

The objective of the present research work was the design, modeling, construction and programming of a prototype of a land explorer vehicle with wirelessly controlled real-time vision in a maximum operating range of 50 meters. The process for selecting the materials and components that made up the vehicle were established through the methodology of deployment of the quality function under weighting criteria, with this a conceptual design was established which was subsequently subjected t...

Pollution by plastic material in our city has caused the need for an efficient recycling method for water storage tanks made of low-density polyethylene, the proposal of this project was born before the possibility that the city of Riobamba has water 24 hours a day. Once the Alao Maguazo Project was completed, the design and construction of a shredder was carried out to recycle water storage tanks for residential use. To know the availability of the material, a survey was carried out among th...

In this titling work, the objective of designing a machine for testing resistance to mechanical fatigue by rotary bending was set and its subsequent construction with the low-cost modality to test in specimens based on 3D-printed polymers using source materials for the benefit of the students who carry out the practices in the Materials Mechanics Laboratory of the ESPOCH, for which investigations were analyzed where it is mentioned that for this application it is essential to carry out the de...
