La invención de las masas : Ciudad, corporalidades y culturas. Rosario, 1910-1945

El libro reconstruye una multiplicidad de experiencias y prácticas urbanas. Sus páginas exploran tiempo-espacios, cuerpos, narraciones y esquemas culturales quebrados en una ciudad que se configura en el umbral de lo masivo. Protagonizada por Rosario y sus agentes, la narración transcurre entre el centenario de la Revolución de Mayo y las vísperas del peronismo. Las fiestas del centenario, la formación de dispositivos disciplinarios y biopolíticos para el cultivo de los cuerpos, la producción y diseminación de espacios verdes, la segregación urbana, la cuestión de la vivienda, las asociaciones y movimientos vecinales, las bibliotecas populares, las prácticas futbolísticas, las exhibiciones cinematográficas, los choques de la incultura y la organización de los carnavales dibujan un mapa y un recorrido curvo y complejo. Roldán ensaya la reunión de procesos, fuerzas y vectores dispersos que se chocan, se rompen y transforman. Es la escritura de una confluencia y sus desperfectos. Universos desconectados se ensamblan por yuxtaposición y contraste en una composición que pretende dar vida y movimiento a una multiplicidad social, corporal, cultural, histórica y urbana.

Optimization of laser-firing processes for silicon-heterojunction solar-cell back contacts

One of the key steps to achieve high efficiencies in amorphous/crystalline silicon photovoltaic structures is to design low-ohmic-resistance backcontacts with good passivation in the rear part of the cell. A well known approach to achieve this goal is to use laser-fired contact (LFC) processes in which a metal layer is fired through the dielectric to define good contacts with the semiconductor. However, and despite the fact that this approach has demonstrated to be extremely successful, there is still enough room for process improvement with an appropriate optimization. In this paper, a study focused on the optimal adjustment of the irradiation parameters to produce laser-fired contacts in a-Si:H/c-Si heterojunctionsolarcells is presented. We used samples consisting of crystalline-silicon (c-Si) wafers together with a passivation layer of intrinsic hydrogenated amorphous silicon (a-Si:H(i)) deposited by plasma-enhanced chemical deposition (PECVD). Then, an aluminum layer was evaporated on both sides, the thickness of this layer varied from 0.2 to 1 μm in order to identify the optimal amount of Al required to create an appropriate contact. A q-switched Nd:YVO4laser source, λ = 532 nm, was used to locally fire the aluminum through the thin a-Si:H(i)-layers to form the LFC. The effects of laser fluences were analyzed using a comprehensive morphological and electrical characterization.

System Integration in a UAS design. An example of undergraduate student's tasks.

Systems integration is the origin of most major difficulties found in the engineering design of aeronautical vehicles. The whole design team must assure that each subsystem accomplishes its particular goals and that, together with the rest of the systems, they all meet the general aircraft requirements.Design and building of UAS is a field of actuation to which leading Universities, research Centers and Aeronautical designers have dedicated a lot of effort. In recent years, a team of students, lecturers and professors at the Escuela Universitaria de Ingeniería Técnica Aeronáutica (EUITA) have been working on the design and building of a UAS for civil observation. The design of multi-mission Unmanned Aerial Vehicles (UAVs) has seen a rapid progress in the last years. A wide variety of designs and applications, some of them really ingenious, have been proposed. The project, which has been going on as a teamwork experience for the last ten years, consists of the design and building of a UAV, and its peculiarity is that it has been carried out entirely by undergraduate students, as part of their Final Research Project. The students face a challenge that includes all the features and stages of an authentic engineering project. We present the current moment of evolution in the process, together with a description of the main difficulties the project has undergone, as a global experience in engineering design and development.

Ruta del Peregrino

Artículo sobre la Ruta del Peregrino en Jalisco, México. La Ruta del Peregrino tiene 117 kilometros de largo, y es una ruta de peregrinación popular en México que antes tenía poca infraestructura. A través de nuevas estaciones de servicio y monumentos arquitectónicos, ahora es atractiva no sólo durante las fiestas religiosas. -------------------- ABSTRACT: "Every year, especially at Easter, more than 2 million people come from all over Mexico to walk along 117 kilometers of the western mountain range in Jalisco, from the village of Ameca to the sanctuary of the Virgin of the Rosary in Talpa de Allende." Recognizing the importance of this religious tourism the State of Jalisco "commissioned a master plan from Dereik Dellkamp and Tatiana Bilbao for the strategic incorporation of spaces for worship, leisure and services with functional infrastructure for the pilgrims' needs." As a result, 15 interventions have been created, including chapels, rest stops and pavilions. [Quotes from Arquine, Autumn 2010].

Absorción acústica a incidencia normal de espumas de aluminio

En este artículo se presentan los primeros resultados de absorción acústica a incidencia normal de espumas de aluminio fabricadas mediante una técnica pulvimetalúrgica. El interés de estas espumas radica en que en ellas se combinan interesantes propiedades acústicas y mecánicas. Se estudian espumas de aluminio de distinta morfología superficial conseguida variando el tipo de precursor y usando materiales de relleno durante el proceso de espumación. Se muestra un estudio comparativo de las espumas fabricadas mediante esta técnica con las espumas comerciales ALPORAS. Las espumas de menor densidad presentan una absorción acústica comparable a la de las comerciales ALPORAS. ABSTRACT. In this paper, the first experimental data of acoustic absorption at normal incidence in aluminum foams generated by a metallurgic technique are presented. The interest of this kind of structures is due to the combination of mechanical and acoustic properties. By changing the precursor type or using filling materials during the foaming process, we have obtained aluminum foams with different surface morphologies. A comparative study between foams fabricated using this technique and ALPORAS commercial aluminum foams is shown. The foams which present the lower density show an acoustic absorption comparable to the ALPORAS commercial ones.

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.

Project based learning activities as a means of adapting conventional curricula to the demands of the 21st century aeronautical engineer: The design and building of the EYEFLY 1.

In this paper we report the process of designing and building the EYEFLY 1, a real UAS platform which has just performed its maiden flight. For the development of this aircraft, 30 groups of students from successive years at the Escuela Universitaria de Ingeniería Técnica Aeronáutica (EUITA) of the Universidad Politécnica de Madrid (UPM) carried out their compulsory End of Degree Project as a coordinated Project Based learning activity. Our conclusions clearly indicate that Project Based Learning activities can provide a valid complement to more conventional, theoretically-based, teaching methods. The combination of both approaches will allow us to maintain traditional but well-tested methods for providing our students with a sound knowledge of fundamental engineering disciplines and, at the same time, to introduce our students to exciting and relevant engineering situations and sceneries where social and business skills, such as communication skills, team-working or decision-taking, can be put into practice.
