The Technological University of Bahía de Banderas offers the career of Advanced University Technician and Engineering in Renewable Energies. Considering that its program of studies is 70% practical and 30% theory, it is of the utmost importance to have inside a system that serves to perform tests of operation and assembly of hybrid systems (wind, photovoltaic) so that students can acquire the necessary skills to a demanding work field. In addition, a space for solar pumping is contemplated, due to one of the eco-economic areas of the regios; agriculture and livestock, although there are irrigation channels there are remote areas with water needs. It is intended to use equipment, accessories and conditions attached to a common facility in the field of work, so that students when they arrive at a private facility are familiar with real, not theoretical marks, models and diagnoses, as the academic modules normally do. of manufacturers.

Electrification of remote areas in the developing world can greatly improve the health and economic standing of the population. Unfortunately, providing power to these remote areas can be expensive and determining the most economical solution is not trivial. This paper presents a method to compare the economics of different small-scale power systems for developing world. In this method, models are developed to describe the performance of power systems composed of diesel generators, batteries with photovoltaics or wind turbines, and hybrid systems. These models are coupled to an optimizer to determine the lowest cost solution that meets the desired system reliability. The reliability is expressed as Loss of Load Probability, and is computed using hourly solar and wind data. In this paper, this method is used to design a power system for a small hospital in the developing world. The results are presented for three sample locations in Honduras, Pakistan, and Uganda. Results show that the economic attractiveness of different technologies varies greatly due to local climatic conditions. The variety and soundness of the solutions found using this method show that it can aid in the design of a small-scale power system for any location in the developing world.

The use of renewable energy sources plays an irreplaceable role in remote areas where the power grid is not available. Photovoltaic power conversion (PV) and wind power conversion are the main types of renewable energy sources used. Hybrid systems are considered the most efficient solution for remote areas that are not connected to the centralized power grid. Renewable energy is attracting the attention of researchers around the world. The main challenge is to combine the various existing sources into a single model in order to benefit from each of them, while complementing each other's disadvantages. The possibilities of managing combined hybrid systems based on renewable energy sources are currently not thoroughly studied. To increase the generation of electrical energy and reduce losses during the operation of these systems, it is necessary to conduct research aimed at improving the interactions of individual nodes of the proposed generation systems and improving the calculation methods for hybrid power plants. The integrated use of solar and wind generation systems can significantly improve energy performance and increase the generation of electrical energy. This paper proposes a method for integrating a solar photovoltaic system, a wind turbine, and a diesel generator connected to a load. An additional load is also connected to the system to absorb excess power. The hybrid system model was developed in MATLAB / Simulink. A controller based on an adaptive neuro-fuzzy inference system was developed and the system analyzed in terms of energy production and consumption. The results obtained show the degree of increase in the reliability and stability of the system.

Ceramic fibers are being used to improve the mechanical properties of metal matrix and ceramic matrix composites. This paper reports a study of the structural and other microstructural characteristics of silicon nitride whiskers using both conventional TEM and high resolution electron microscopy.The whiskers were grown by T. E. Scott of Michigan Technological University, by passing nitrogen over molten silicon in the presence of a catalyst. The whiskers were ultrasonically dispersed in chloroform and picked up on holey carbon grids. The diameter of some whiskers (<70nm) was small enough to allow direct observation without thinning. Conventional TEM was performed on a Philips EM400T while high resolution imaging was done on a JEOL 200CX microscope with a point to point resolution of 0.23nm.

The aim of the article is to develop a method for calculating water losses from irrigation channels in determining the permeability of rock in the zone of filtration flow on the basis of the law of infiltration A.N. Kostyakov using the results of studies of free filtration from pits and foundation pits in loess loams. Pressure movement of water in irrigation canals is subject to the laws of two-phase flow, in which – in contrast to the Darcy law for the zone of saturation plays an important role, the volume and its change in time. The filtration rate (VF) increases with increasing rock moisture (θ) along the S-curve, while the pressure gradient (I = dh/dz) decreases. The dependences of these parameters on the pressure are represented by power functions, and their product CDP = VFI does not change in time and can serve as a characteristic of the filtration flow under the channel. When installing paired piezometers near the water chore line in the channel and determining the graph I(t) by the value of the twophase flow constant CDP, it is possible to calculate the filtration rate at a number of times and the water losses during unsteady filtration. Water losses from the channels at equilibrium humidity increases with increasing head according to the formula A.N. Kostyakova, in which the water permeability of rocks is characterized by a steady filtration rate at a head of 1.0 m, and the gradient is the function of pressure. The application of the proposed method of calculating losses in the design of irrigation systems will increase the reliability of the justification of the volume of anti-filtration measures and the forecast of the groundwater level.
