The purpose of this paper is to analyse the maturity of project management at the Faculty of Engineering and Architecture of the University of Pamplona. An instrument of the Kerzner-PMMM maturity model was applied. The respondents are part of the teaching and administrative academic staff. With the model chosen, a medium-low degree of maturity is observed, allowing an opportunity to unify processes and seek alternatives until a high level and success is achieved in the projects.

La investigación analiza la resonancia sub síncrona en un sistema de energía eléctrica, abordando este problema desde el estudio de sus causas primarias hasta el diseño de una solución general. Desde un enfoque cuantitativo, los datos de vibración recogidos tanto de forma estable como transitoria durante el arranque de los compresores tienen como objetivo generar curvas de órbita y modelos matemáticos predictivos y preventivos. Los resultados muestran disminución de consumo para condiciones iguales de temperatura y velocidad, en vibración las características de órbitas truncadas de la fricción interna relacionadas con el aumento de la velocidad, la cascada de espectro completo se construye a partir de dos transductores; se concluye que operar la torre de enfriamiento con dos bombas de recirculación con los ventiladores a igual velocidad, reduce pérdidas por consumo eléctrico, la vibración tanto en modo estacionario como transitorio genera modelos predictivos para la prevención del deterioro del rotor y la inestabilidad del compresor

Advanced oxidation processes such as TiO2/UV heterogeneous photocatalysis are suitable treatment methods for wastewater with high pollutant loads such as landfill leachates. Optimizing the variables that influence the process is a fundamental aspect. However, in this regard, experimental conditions are limited in terms of resources and time, which is why modeling allows obtaining a general understanding of the phenomenon from a set of experimental data. This work sought to model the photocatalytic process via multivariate polynomial regression, considering variables such as the catalyst concentration, the pH level, and the accumulated energy concerning the percentage of degradation in terms of dissolved organic carbon (DOC). The implemented fitting method resulted in a third-degree polynomial with an R2 of 0,8652, concluding that the model and its conclusions are valid. Moreover, with greater degrees, the model curve overfitted, even with better R2. DOC abatement showed a negative correlation with pH and the catalyst dose, while an opposite trend was observed for the accumulated energy. The model predictions allow inferring that, at low catalyst doses and medium and high pH levels, it is possible to find maximum degradations at low cumulative energies
