The uncertainty of the energy demand in existing mediterranean urban blocks
2013
The objective of the paper is to describe a stochastic model that has been developed to obtain load profiles for household electricity. For the study, several profiles have been generated in order to simulate the electrical demand of a residential building block or neighbourhood and evaluate the uncertainty of its energy use. The paper is divided in three different parts: development of the model, validation and determination of the uncertainty demand. In the first parts the basis of the model and how it works is explained. The second one represents the validation of the model, the input data and its results. The last step is focused on a statistical analysis of the electricity demand of a …

PUBLIC POLICY PLANNING TO ENHANCE THE RESILIENCE OF SOCIO-ECOLOGICAL SYSTEMS TO CLIMATE CHANGE: OPERATIONALIZING RESILIENCE CONCEPTS FROM A DYNAMIC P…
This study outlines a system dynamic based approach to the planning for resilience in food systems to climate change. The processes described and the insights gained are novel in the literature since they focus on describing operational aspects of resilience that can be generalized to multiple contexts and problems. On the one hand, the process described offers an aid for researchers and practitioners operationalizing resilience in public sector settings. Simultaneously, the insights gained from multiple stakeholder discussions and modelling work open new questions regarding the general mechanisms driving resilience in food systems. Climate change is threatening the extent to which social, …
La riqueza socioemocional: resiliencia y desempeño en la empresa familiar
2023
El estudio de la relación: Riqueza Socioemocional (SEW) - Desempeño de la organización ha crecido significativamente, sin embargo, los hallazgos empíricos presentan diversas controversias, suscitando recientemente el interés de los académicos por identificar constructos mediadores que expliquen los efectos indirectos que SEW puede generar sobre el desempeño. Dada la coyuntura económica mundial y que aún es escaso el conocimiento sobre la forma en que SEW desencadena cambios en los niveles de desempeño de la firma, la presente tesis propone un nuevo mediador en tal relación: la resiliencia. Para ello, se emplea una estrategia sistematizada en tres estudios. El primero centrado en el diseño d…
Mathematical modelling of Membrane Bioreactors
2015
Mathematical modelling of membrane bioreactors (MBRs) for wastewater treatment has targeted either the biological processes (treatment quality target) as well as various aspects of system management. However, the high number of interactions among the involved physical – chemical processes, hampers a straightforward mathematical modelling. This circumstance is much more emphasized for submerged MBR systems where the membrane is immersed in an aeration tank. One of the main crucial point that prevents a comprehensive understanding is the interpretation of the fouling phenomenon and its connections with the biological processes. An overall mathematical model for MBR has not been completely est…

ESTIMATION OF ATTRIBUTE IMPORTANCE BY CHOICE TIME IN A RANKING TASK
2010
The evaluation of the quality of products and services as a function of their attributes has been broadly implemented in marketing research. The current methods for identifying important attributes and prioritize them suffer from theoretical and practical limitations. The former are related to the choice of the most appropriate model for the specific experimental context, the latter are due to the large amount of variables (cognitive, context and survey variables) affecting the chosen model. This work aims at presenting a new method for capturing consumer attribute preferences and estimating the relative importance weights by using the choice time in a ranking task. All is made through an e…
Ciclo del carbono y modelización biogeoquímica de un lago somero hipertrófico: la Albufera de Valencia
2015
Los lagos someros son uno de los ecosistemas acuáticos más numerosos a nivel global y hacen posible el desarrollo de multitud de actividades de interés económico y recreativo. En las últimas décadas, gran parte de estos lagos se han visto sujetos a un proceso de eutrofización cultural que a menudo conlleva una transición desde un estado "claro" caracterizado por una alta transparencia del agua y gran abundancia de macrófitos, a un estado "turbio" caracterizado por una baja transparencia del agua, dominancia de fitoplancton y macrófitos sumergidos prácticamente ausentes. El cambio que experimentó la Albufera de Valencia al estado turbio a principios de los años 1970 como resultado de un inte…
Palermo. Un museo virtuale - Palermo. A virtual museum
2016
Conoscenza, conservazione e valorizzazione sono tra gli obiettivi principali delle discipline riguardanti il disegno, il rilievo e la restituzione grafica dell’architettura, che non si fermano soltanto alla documentazione dello stato di fatto ma comprendono anche ricostruzioni congetturali del processo diacronico di modificazione del monumento ai fini di una sua più ampia conoscenza; la storia del monumento si inserisce, in tal modo, nella storia della città e dei suoi cambiamenti culturali; queste nuove immagini sono veri e propri importanti elementi di un "virtual museum" del sito e, più in generale, della città sulla quale esso insiste. Da molti anni, ormai, i docenti, gli assegnisti di …
BENEFICIOS RELACIONALES, SATISFACCIÓN Y LEALTAD EN EL COMERCIO MINORISTA: UNA COMPARATIVA INTERSECTORIAL
2009
RESUMENEn el contexto del marketing de relaciones, resulta de gran importancia para el establecimiento minorista identificar el tipo de beneficios de la relación que influye en mayor medida sobre sus resultados en términos de satisfacción del cliente y lealtad hacia el minorista, de manera que se garantice una relación continua y satisfactoria. Dichos beneficios pueden tener distinto peso en función del tipo de actividad llevada a cabo por el minorista. El presente trabajo pretende analizar empíricamente un modelo que refleje los distintos tipos de beneficios relacionales obtenidos por los clientes, así como los beneficios obtenidos por la organización en términos de lealtad del consumidor …
