El levantamiento de arquitectura como dibujo de concurso sin tiempo: los dibujos del Pantheon desde el Renacimiento hasta la actualidad

En un estudio reciente sobre ?Los cuatro libros de arquitectura? de Andrea Palladio, Javier Rivera (2008) propone la hipótesis que el autor utilizó la publicación para influir en la adjudicación de obras en Venecia. Aunque no se tratara de un concurso formalmente establecido el dibujo de arquitectura en general y el de levantamiento en particular se utilizaba como herramienta competitiva para comparar habilidades. La obra de documentación de Antoine Degodetz en Italia también es fruto de una difícil selección para adjudicarse y mantener en los años la beca de estancia en la Academia de Roma. Puesto que el levantamiento es una operación crítica e interpretativa cada arquitecto entiende su trabajo como una mejora personal respeto al anterior y vuelve a dibujar obras ya documentadas previamente. El levantamiento y el dibujo se utilizan para superar los límites de los predecesores o contemporáneos posicionándose en continua comparación con otros trabajos sobre el mismo tema y configurándose efectivamente como un dibujo de concurso sin tiempo. El trabajo realizado tiene como objeto el análisis con esta óptica de una serie de dibujos de levantamiento del Pantheon. El modelo se ha elegido por su indiscutible valor histórico y por su presencia en un gran número de los estudios de edificios antiguos documentados a partir del Renacimiento hasta la actualidad.

Relationship between solar radiation on watercore on apple fruit assessed with MRI

This work is a preliminary studio of the possibility of assess a relationship between solar radiation and watercore development on apple fruit, during maturation, using a non destructive method such as Magnetic Resonance Imaging (MRI). For such purpose, several low cost solar radiation sensors were designed for the trial and placed at 2 different heights (1.5 and 2.5 m) on 6 adult ?Esperiega? apple trees, in a commercial orchard in Ademuz (Valencia). Sensors were connected along 27 days, during the end of the growth period and start of the fruit maturation process, and radiation measurements of the a-Si sensors were recorded every 1 minute. At the end of this period, fruits from the upper and the lower part of the canopy of each tree were harvested. In all, 152 apples were collected and images with MRI. A Principal Component Analysis, perfomed over the histograms of the images, as well as segmentation methods were performed on the MR images in order to find a pattern involving solar radiation and watercore incidence.

Experimental investigation on box-wing configuration for UAS

The range for airframe configurations available for UAS is as diverse as those used for manned aircraft and more since the commercial risk in trying unorthodox solutions is less for the UAS manufacturer. This is principally because the UAS airframes are usually much smaller than the manned aircraft and operators are less likely to have a bias against unconventional configurations. One of these unconventional configurations is the box-wing, which is an unconventional solution for the design of the new UAS generation. The existence of two wings separated in different planes that are, however, significantly close together, means that the aerodynamic analysis by theoretical or computational methods is a difficult task, due to the considerable interference existing. Considering the fact that the flight of most UAS takes place at low Reynolds numbers, it is necessary to study the aerodynamics of the box wing configuration by testing different models in a wind tunnel to be able to obtain reasonable results. In the present work, the study is enhanced by varying not only the sweepback angles of the two wings, but also their position along the models’ fuselage. Certain models have shown being more efficient than others, pointing out that certain relative positions of wing exists that can improve the aerodynamics efficiency of the box wing configuration.

Operational characterisation of a Micro-SME producing farmhouse cheese in the south of Venezuela

A piece of research is presented that was conducted on the Guayanes Farmhouse Telita Cheese Producers Network located in the Piar and Padre Chien rural municipalities of Bolivar state in Venezuela. Guayanes telita cheese is a regional dairy product. The producers are to be found in a rural area with a high potential for marketing the label in the Southern Common Market (MERCOSUR). This market is the focal point of the strategic importance of this study for the Region and the Country. The research is of a descriptive scope conducted in the field. A questionnaire based on good food production practice was used as a data gathering technique. The final sample comprised 30 production units. Statistical processing was performed with version 15.2 of the STATGRAPHICS Centurion computational tool. The results would appear to confirm previous studies that point to the existence of factors that prevent these Micro-SMEs from guaranteeing the food safety of the product. The results indicate that new lines of research need to be opened up. These are oriented towards formulating strategies for the continuous improvement of these micro-SMEs, including quality control indicators.

Activity based costing, time-driven activity based costing and lean accounting: differences among three accounting systems' approach to manufacturing

Choosing an appropriate accounting system for manufacturing has always been a challenge for managers. In this article we try to compare three accounting systems designed since 1980 to address problems of traditional accounting system. In the first place we are going to present a short overview on background and definition of three accounting systems: Activity Based costing, Time-Driven Activity Based Costing and Lean Accounting. Comparisons are made based on the three basic roles of information generated by accounting systems: financial reporting, decision making, and operational control and improvement. The analysis in this paper reveals how decisions are made over the value stream in the companies using Lean Accounting while decisions under the ABC Accounting system are taken at individual product level, and finally we will show how TD-ABC covers both product and process levels for decision making. In addition, this paper shows the importance of nonfinancial measures for operational control and improvement under the Lean Accounting and TD-ABC methods whereas ABC relies mostly on financial measures in this context.

Economic analysis of the renewable energy policies in the European Union

The European energy sector is undergoing a major transformation and is facing a series of difficult challenges. These include a high and increasing dependence on external energy resources; dramatically reduce the need for the emissions of greenhouse gases to meet environmental objectives and the difficulties related to the promotion of energy market effectively integrated and competitive. Some of the policies associated with the various objectives are sometimes in conflict with each other, while in other cases are mutually reinforcing.The aim of this paper is to do a scienti?c analysis of the developments so far and the expectations for the coming period focusing on the pillars of energy policy in the EU in terms of security of supply, environment, climate change and promoting a competitive and integrated market. The use of renewable energy sources is seen as a key element of European energy policy and should help to: reduce dependence on fuel from non-member countries; reduce emissions from carbon-based energy sources, and; decouple energy costs from oil prices.

Characterization of underground cellars in the Duero Basin by GNSS, LIDAR and GPR techniques

The underground cellars of the Duero River basin are part of spread and damaged agricultural landscape which is in danger of disappearing. These architectural complexes are allocated next to small towns. Constructions are mostly dug in the ground with a gallery down or "barrel" strait through which you access the cave or cellar. This wider space is used to make and store wine. Observation and detection of the winery both on the outside and underground is essential to make an inventory of the rural heritage. Geodetection is a non-invasive technique, suitable to determinate with precision buried structures in the ground. The undertaken works include LIDAR survey techniques, GNSS and GPR obtained data. The results are used to identify with centimetric precision construction elements forming the winery. Graphic and cartographic obtained documents allow optimum visualization of the studied field and can be used in the reconstruction of the place.

Muchos son los aspectos que interesan en la arquitectura de Lacaton y Vassal y que son analizados en los distintos artículos que se incluyen en esta publicación. En ocasiones, las acciones humanas tienen la cualidad de despertar un interés que va más allá del objeto mismo para el que fueron realizadas. La mayor parte de los proyectos y obras de Lacaton y Vassal posee esta cualidad que, entre otras cosas, se traduce en un alto valor pedagógico que, en este caso, tiene carácter metodológico.

Educación en el contexto de las IDE.

La demanda de recursos humanos capacitados es fundamental para la puesta en marcha de las iniciativas IDE, así como la generación de estrategias que contribuyan a su difusión y acercamiento a los distintos niveles educativos. En este contexto, se indaga en la normativa relacionada con IDE para identificar qué papel se le asigna a la educación. En particular INSPIRE apoya implícitamente la importancia de la educación y formación en el marco de las instituciones y organizaciones. Mucho más explícitas son las recomendaciones lanzadas desde instituciones y organizaciones nacionales e internacionales, como es el caso de la IDE de España, la iniciativa GSDI y el OGC. En algunos de estos casos, las organizaciones disponen de material de apoyo a la docencia (videos instructivos, listas de discusión, cursos, etc.) o recursos que han realizado orientados a otros niveles educativos, específicamente a la Educación Secundaria Obligatoria de España. Se hace una mención especial al reciente libro ?Fundamentos de las Infraestructuras de Datos Espaciales?, que representa un nuevo recurso susceptible de ser utilizado para impartir docencia. Este trabajo, incluye una parte del contenido incluido en uno de los capítulos del libro. Se presentan a continuación una serie recursos educativos de referencia susceptibles de ser utilizadas para la formación en IDE. Finalmente, se presentan unas breves conclusiones haciendo hincapié en la necesidad de dar a conocer a los ciudadanos las potencialidades de las IDE a través de distintas estrategias de formación y difusión orientadasa los distintos niveles educativos con la colaboración de instituciones relacionadas con la IG.
