Este tipo de reflexiónes, por su carácter inestacionario, posee tres variables independientes (x, y, t) y son fenómenos más complejos que aquellos generados en flujos estacionarios o pseudo-estacionarios que dependen de dos variables independientes.

Although being very energy efficient, the compass-like gait bears the inherent problems of forcing the swing-leg tip to below-ground position while walking and allowing for almost no terrain irregularities. In this paper, an underactuated biped based on the double pendulum is made to walk via swinging the leg in the direction opposite to that of the compass-like gait. Actuation torque on the stance foot is required to change signs during leg swing in order for the pre- and post-impact states to allow for stable limit-cycle walking. This sign-changing torque is implemented by means of a simple control strategy that generates a whip-like gait and allows the biped to walk over irregular terrain and to admit a broad range of initial conditions. Simulations are given including control tuning guidelines for stable walking.","PeriodicalId":318846,"journal":{"name":"2022 IEEE Biennial Congress of Argentina (ARGENCON)","volume":"275 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133133786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then an efficiency mapping test is done experimentally to validate a simple direct-quadrature model. The good correlation obtained from this model, with an error lower than 2% for the majority of the operating points, shows that the model is adequate for representing the behavior of the machine. Future work will be oriented to develop more complex models and to validate simpler experimental parameters determination techniques.","PeriodicalId":318846,"journal":{"name":"2022 IEEE Biennial Congress of Argentina (ARGENCON)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115976662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

La introducción de este sistema de ecuaciones requiere de considerar que el sistema se encuentra localmente en equilibrio termodinámico, lo cual se verifica según el criterio de McWhirter. Además, se modela la evolución de la temperatura del plasma mediante la aplicación de la conservación de la energía de la lámina de plasma, considerando el calentamiento por efecto Joule, las pérdidas por radiación y la energía asociada a la fuerza de Lorentz. Al modelo se lo implementa numéricamente, lo que permite estimar parámetros de rendimiento, como la masa ablacionada, el bit de impulso, el impulso específico y la eficiencia propulsiva, entre otros.

In addition, the temporal fluctuation of water-affected surfaces in response to the seasonal cycle of precipitation was explored, which would be influenced by the antecedent water storage. Most of the water-affected surfaces are composed of Mixed Water, Open Water surfaces are made up of certain water bodies with a high frequency of occurrence, located in the lower part of the basin. A sector of accumulation in the upper part coincides with an area of \"cañadas\". In other sectors of the basin, the surfaces affected by water have low frequencies of occurrence.
