Descriptive Study of a Rotary Machine Affected by Misalignment and Imbalance Applying the Wavelet Transform

Increasing An algorithm is developed to identify differences between concrete slabs with some type of Crack and Fissure discontinuity. The Fourier transform is used as a basis. Different types of fil-ters were evaluated within the image processing algorithm, in order to adapt favorably to the discontinuity detection process, allowing the image data to be read in the frequency domain, generating a figure of merit to compare the image. where there are no discontinuities and those that have some alteration in their structure.

The objective of the development of the prototype or scale model of production of hydrogen and oxygen through the electrolysis process of water is to generate an alternative with a sustainable approach, which proposes the supply or source of energy initially with a direct current power source. replaceable in the future by a photovoltaic solar system. For the development of the prototype, it began with the academic compilation of information, then the model was made in CAD, followed by the need to integrate an electronic control system and a mechanical system to obtain the final model, materials were selected and used premises for the development of the two systems, the electronic and physical schematization was carried out, chaired by the assembly and field experimentation. It is important to highlight that the constructed scale model generates hydrogen and oxygen with a low current consumption and a constant voltage, the maximum point of gas generation is the maximum point of energy consumption and its relationship is almost linear.

The objective of the project is to carry out the dimensioning of a photovoltaic system that allows its integration with a condensation system for the production of fresh water in isolated areas (Rural), in such a way that a sustainable condensation application capable of producing water is generated. sweet to supply small groups of inhabitants in areas where the basic supply of liquid is deficient. The study area is the Department of Santander, Colombia, specifically in the Municipality of los Santos and the area known as Mesa de los Santos, in which difficult geographical conditions are presented such as: altitude of 1650 meters above sea level and deficiency in aquifers. The methodological development proposes the analysis of the meteorological conditions of the area, the identification, selection and dimensioning of the condensing system and the photovoltaic system through the amp-hour method and the software system advisor model (SAM). Additionally, a CAD model is developed to obtain the complete schematization of the model and carry out a simulation process to analyze the behavior of the integration of the aforementioned systems. Finally, a techno-economic analysis of the proposed system is carried out.
