Stabilitätsbetrachtungen zu VSC-HGÜ-Systemen

  • Sanz López, Víctor
Der Eintritt in das 21. Jahrhundert hat viele neue Erfindungen gebracht, aber es gibt noch viele Probleme für die Zukunft. Die nicht erneuerbaren Energiequellen können bald der Vergangenheit angehören und jetzt kommt der Moment für neue Energien, um die ökologische Nachhaltigkeit in der Zukunft zu erreichen. Noch brauchen diese neuen Energien viele neue Entwicklungen in der Technik., Outgoing

Background. The findings of internation- al studies suggest high rates of interperson- al violence and posttraumatic stress disorder (PTSD) among patients with schizophrenia spectrum disorders. Only few studies, how- ever, have so far been conducted in the Ger- man-speaking countries. Objectives. The aim of our study was to determine the prevalence of lifetime experi- ences of interpersonal violence and comor- bid PTSD among inpatients in a German uni- versity hospital. Method. In N=145 consecutively admitted patients with schizophrenia spectrum disor- ders (67% male) the structured trauma in- terview (STI) was used to assess experiences of interpersonal violence and the structured clinical interview for DSM-IV (SCID) to assess comorbid PTSD. Results. Sexual violence under the age of 16 years was reported by 17% of the patients (women 27%, men 12%). Approximately one third (32%) reported physical violence by pa- rental figures (women 38%, men 29%). At least one form of early violence (sexual or physical) was reported by half of the women (48%) and one third of the men (34%). Neg- ative sexual experiences later in life were re- ported by 17%, physical violence by 38% and at least one of these forms by 48% of the pa- tients. In total two thirds of all patients (66%) reported experiences of violence during their lifetime. The prevalence of acute PTSD was 12%. Another 9% of patients had a subsyn- dromal PTSD. Conclusion. The present study confirmed the high rates of experiences of interperson- al violence and comorbid PTSD in a German sample of patients with schizophrenia spec- trum disorders. Violence and it's consequenc- es should therefore be routinely assessed and the full spectrum of trauma-specific therapies should be integrated into the treatment of this group of patients.

Die ersten offiziellen Ausgrabungen in Ampurias (Empuries, L'Escala, Provinz Girona): 1846

  • Buscató i Somoza, Lluís
  • Pons Pujol, Lluís, 1971-
En el año 2008 tuvo lugar el aniversario del centenario de las excavaciones arqueológicas en la ciudad greco-romana de Ampurias. Precisamente las investigaciones de esa época tienen un significado cultural y simbólico muy importante para el desarrollo de la autognosis de Cataluña a comienzos del siglo XX. El presente artículo intenta llamar la atención sobre los verdaderos comienzos de las investigaciones sobre la antigua ciudad, que habían comenzado bastante antes. Si nos concentramos en considerar los lugares de patrocinio público<br> las excavaciones privadas fueron habituales en todas las épocas<br> entonces las excavaciones científicas comenzaron siete décadas antes. Responsable fue la Comisión de Monumentos de Girona, que contó con el apoyo financiero de la Diputación Provincial.

Entwicklung eines abgaskühlers

  • Carrillo Forster, Roman
PFC del programa Erasmus elaborat a Hochschule Darmstadt University of Applied Sciences, The project is part of a cooperation between Hyuandai GmbH and Ecokat, Ecokat is a company dedicated to the construction of catalytic converters and particulate filters for diesel engines. The testing of Ecokat catalysts in Hyundai engines are done in the laboratory of the Hochschule Darmstadt, equipped with testing banks and measuring devices. Specifically, the subject of my project is to develop a system to cool the exhaust of a diesel engine with 80 kW of power. The reason for having to cool the exhaust gas is to check whether the temperature influences the performance of the catalyst and particulate filter, and the goal is to cool the exhaust gases 50 º C. Above all I asked to choose within a liquid and a air cooling. As a cooling liquid required more pieces and more accurately due to the tightness I decided to do the calculations with cooling air. The first step was to calculate the composition of exhaust gas to calculate their physical and chemical characteristics with the help of the data bank of tests. After calculating the internal and external convection of the system, raising it to two different designs, a single tube with cooling fins and the other three tubes with the same smooth and cooling fins. To simplify the calculations I made an Excel sheet to experiment with different diameters, thicknesses, materials, etc.. In the end I decided to design a single tube with squared fins, as the design of three tubes would have had masses of gas friction losses. The choice of squared fins was for costs reasons, since copper is sold in square plates, and it was easier to cut the square-shaped and weld them to the tube. The building plans are made with Catia v5, after I asked the cooper and then the workers of the workshop built the radiator at the University. Once assembled, I did the tests, check results were not unexpected, since it not obtained the calculated cooling, especially at low rpm and low power. To promote the heat transfer coefficient I introduced a spring inside the tube, so the turbulence of the gases increased. After that I got good test results at low rpm and low power but at high power and at high rpm the results were worse than those calculated, probably because the spring had no effect. In conclusion, I think the reason for the difference between the calculated values and there obtained on the testing bank are because the formula that I used is based on ideal cases and gives approximated values with poor accuracy.

Parametrische Optimierung eines Querträgers

  • Orantes Riera, Manel
Desarrollo de una metodología que permita obtener de manera sistemática y, a partir de unas condiciones de contorno fijadas, una primera gometría del conjunto (travesía+deformables). La optimización paramétrica debe tener la suficiente flexibilidad para adaptarse a diferentes ensayos de choque (tanto de baja velocidad como de alta velocidad). Puntos destacables del proyecto: 1)Definición de los requisitos que debe cumplir el conjunto (traviesa+deformables) 2)Contraposición de diversos procedimientos de optimización 3)Elección y definición del procedimiento de optimización empleado (variables, restricciones, función objetivo,...) 4)Desarrollo de la optimización 5)Comprobación y valoración de los resultados obtenidos, Outgoing
