    Análisis Cinemático y Dinámico del Mecanismo de Cuatro Barras de una Máquina de Ejercicios
    (LACCEI Inc., 2018-09) Hurel, Jorge; Flores Nicolalde, Francisca Angelica; Amaya, Jorge; Calderon, Clemente; Suarez, Nicole
    La máquina de ejercicios al aire libre (Pony), se encuentra instalada en la mayoría de parques de la ciudad de Guayaquil, es un ejemplo muy común de un mecanismo de cuatro barras impulsado por el movimiento humano. El objetivo principal de este proyecto es analizar este mecanismo, mediante un estudio cinemático y dinámico, usando modelado analítico en MATLAB por medio del método cinetostático, y modelado de sistema multicuerpo mediante el software ADAMS (Automatic Dynamics Analysis of Mechanical Systems). Los resultados corroboran la exactitud de los métodos empleados.

    Domestic Plastic Waste in the city of Guayaquil: Generation Rate and Classification
    (LACCEI Inc., 2021-07) Hidalgo, Jose; Amaya, Jorge; Soto, Manuel; Caamaño, Daniel
    A significant contributor to the waste streams nowadays are domestic plastics. However, in Ecuador most of them end up in the local landfills impacting the environment in a major form. The aim of this paper is to classify and quantify the total amount of household plastics generated for the city of Guayaquil. To obtain this, we developed a novel methodology with the help of students from a local university. Each household produces approximately 1.64 kg of plastics daily. From all plastic waste, PET occupies the 1st place as the most disposed of with approximately 44%, followed by HDPE with 20% and PP with 10%.

    Waste to Energy Potential of Domestic Waste Cooking Oil in Guayaquil: A review.
    (LACCEI Inc., 2020-07) Hidalgo, José; Coello, Silvia; Crespo, Tania; Amaya, Jorge; Soto, Manuel; Jervis, Freddy; Moreira, Cesar
    This paper examines the opportunity for waste cooking oil as a potential source of energy by means of (i) production of biodiesel, (ii) direct burning and (iii) biodegradation. It offers a profound review of existing literature and it measures possible uses of the waste cooking oil produced in the city of Guayaquil. In addition, important chemical and physical properties are presented after the development of a sampling process for after laboratory testing. Conclusions show that the most suitable technology is biodiesel generation, followed by biodegradation, but direct burning is found to be not a possible solution due to its kinematic viscosity.
