this paper presents a lumped parameter dynamic model of a Fresnel collector field of a solar refrigeration plant. The plant is located in the Escuela Superior de Ingenieros of the University of Seville. The dynamic model parameter model developed can be used as a control model or as a simulation tool to test controllers. The lumped parameters have been determined by using real data from the plant in different operating conditions. The model has been validated against a data validation set obtained from the plant. The model has shown to reproduce the system behavior with a good compromise in accuracy and model complexity.
This is a slightly modified and simplified version of a protocol by Thomas G.W. Graham et al, which is available at https://gitlab.com/tjian-darzacq-lab/bearmix and has been described in depth in the article 10.1371/journal.pone.0246647, for the recombinant expression of a E602D mutant of Taq DNA polymerase in pET-28a that is available in Addgene (Addgene plasmid # 166944 ; http://n2t.net/addgene:166944 ; RRID:Addgene_166944). The main goal of this protocol is to eliminate the use of large volumes for dialysis and potential issues with the protein crashing out of the solution due to the use of concentrators for buffer exchange of this enzyme into storage conditions.
<p><span style="font-family: Arial; font-size: x-small;">En esta comunicación se muestra la tarea llevada a cabo por profesores de diferentes asignaturas de la titulación de Ingeniería Técnica en Topografía de Barcelona, dentro de un proyecto de innovación docente financiado por la </span><em style="font-family: Arial; font-size: x-small;">Universitat Politècnica de Catalunya</em><span style="font-family: Arial; font-size: x-small;">. Se ha desarrollado una herramienta para que el estudiante, frente a un problema práctico que involucra varias asignaturas de la carrera, se enfrente a su resolución a partir de datos provenientes de observaciones virtuales, pueda consultar la teoría correspondiente a las diferentes materias que intervienen, realice los cálculos necesarios con ayuda de las herramientas matemáticas implementadas y compruebe el avance de su aprendizaje y el grado de comprensión de las materias mediante la resolución de tests de autoevaluación. </span></p><p> </p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
