    Diseño y construcción de un prototipo de turbina tipo tornillo sin fin para la iluminación y electrificación de cercados eléctricos en las comunidades y sectores rurales del cantón Latacunga
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-07) Guilcamaigua Chacon, Bryan Steeven; Yunapanta Velastegui, José Luis
    Due to the need to improve the energy supply in the rural sectors of the Latacunga canton, it is proposed to carry out the respective design, improving the quality of life of the inhabitants of the sector. In this research, the data obtained from the water channel of the Anrracas sector in the parish of Juan Montalvo in the city of Latacunga were used, taking into account as important data the value obtained from the water flow, the design and mechanical construction of the Archimedes screw type turbine prototype was elaborated, for the realization of this project several scientific articles and investigative documents referring to the subject were used. The construction of the design was made based on the data of the flow of the channel, for this a previous sketch was made in a 3D software simulator of mechanical design, for the proper functioning of the screw in the water was considered an average flow of 0.5 to 1.5 cubic meters per second. The materials for the construction and assembly of the prototype were selected after the analysis of the weight of the screw, dimensions, resistance of the structure, the materials selected for the assembly of both the structure and the turbine are corrosive materials because the turbine prototype will be submerged in water. Once the operation tests were carried out with a multimeter, the voltage measurement was taken, resulting in 13.5 V, and 550 rpm, with the values obtained led lamps were turned on, obtaining an optimal result for the project's functionality.

    Análisis estructural del desempeño sísmico del edificio de la Facultad de Ciencias Agropecuarias bloque 1 mediante la medición de vibraciones
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2021-09) Campos Nuñez, William Dario; Cevallos Cabrera, Jorge Washington
    In the present research work, a qualitative and quantitative analysis was carried out to determine the seismic vulnerability of the building of the Faculty of Agricultural Sciences Block 1 of the Technical University of Ambato. The qualitative analysis was carried out through a quick visual inspection with the forms proposed by the FEMA 154 and NEC 15 methodologies, where it was determined that the structure has a high degree of seismic vulnerability caused by irregularity in: plant and elevation, year of construction, the type of soil and hitting problems with adjacent structures. The quantitative analysis was done using the ETABS software for which we found out the behavior of the structure with a modal spectral analysis in which it was determined that it does not comply with the NEC 15 standard because it has large floor drifts and its vibration period is not among the ranges established by standard. With these results of the two methodologies used, a proposal for the reinforcement of the building was made, which at a global level is the placement of cutting walls that provide greater rigidity and at the local level of the elements with a steel jacketing in both beams and columns, then the quantitative analysis was carried out again where it was possible to comply with the requirements established by the Ecuadorian Construction Standard.
