The HIRM+ Flight Dynamics Model

The major objective of the GARTEUR Action Group on Analysis Techniques for Clearance of Flight Control Laws FM(AG-11) is the improvement of the flight clearance process by increased automation of the tools used for modelbased analysis of the aircraft’s dynamical behaviour. What is finally needed are techniques for faster detection of the worst case combination of parameter values and manoeuvre cases, from which the flight clearance restrictions are be derived. The basis for such an analysis are accurate mathematical models of the controlled aircraft. In this chapter the HIRM+ flight dynamics model is described as one of the benchmark military aircraft models used within FM(AG-11). HIRM+ originates from the HIRM (High Incidence Research Model) developed within the GARTEUR Action Group on Robust Flight Control M(AG-08). In building the HIRM+, additional emphasis has been put on realistic modelling of parametric uncertainties

Theory of Evolution and Faith in Creation On the History of a Tense Relationship

This overview of the history of the idea of evolution includes the work of many European scholars often omitted from such accounts, particularly in the United States. It provides a case study in the origin of cultural tensions, owing to the attempts of some scientists and theologians, without sufficient interdisciplinary understanding, to undermine public confidence in each other\'s proper authority

Zum Einsatz von MICRO-FCS und Symphony für die strategische Unternehmensplanung

In einer Fortgeschrittenen-Übung zur Unternehmensgesamtplanung wurden von Studenten der Christian-Albrechts-Universität Kiel Methoden und Verfahren zur strategischen Planung implementiert und präsentiert. Während eine erste Gruppe die Planungssprache MICRO-FCS einsetzte, implementierte eine zweite Gruppe ihre Anwendungen mit dem integrierten Software-Paket SYMPHONY. In beiden Gruppen wurden interessante und überraschende Programme geschaffen. Im Verlauf der Übung stellten wir eine erhebliche Verbesserung bei der Implementierung fest. In den SYMPHONY-Applikationen wurde durchgehend eine Makro-Steuerung mit eigenen Befehlsmenüs programmiert, und auch in der MICRO-FCS-Gruppe setzte sich ein eigener Maskenaufbau mit F-Tasten-Steuerung, in zuletzt fast professioneller Qualität, durch..

Anatomie einer Leidenschaft : Anmerkungen zu Bernardo Bertoluccis transgressivem Liebesfilm DER LETZTE TANGO IN PARIS

Mit Ultimo tango a Parigi gelang Bernardo Bertolucci ein Skandalerfolg Anfang der siebziger Jahre. Begünstigt durch Gerüchte um extreme Sexszenen, gerichtliche Klagen und Verbote, spielte der Film, dessen Budget lediglich bei 1,2 Millionen Dollar lag (vgl. David Thompson: Last tango in Paris. London 1998, S. 16), insgesamt über 40 Millionen Dollar ein (vgl. Dietrich Kuhlbrodt: L´ultimo tango a Parigi. In: Peter W. Jansen / Wolfram Schütte: Bernardo Bertolucci. München 1982, S. 170). Obwohl Ultimo tango a Parigi in den USA als Pornofilm vermarktet wurde (vgl. ebd.), erkannte die Filmkritik schon früh seine künstlerische Qualität

Stand und Perspektiven der Informationsverarbeitung in Banken

Der vorliegende Bericht verfolgt das Ziel, die aktuelle Situation der Daten- und Informationsverarbeitung in Banken vor dem Hintergrund der gravierenden Umwälzungen innerhalb der Bankwirtschaft zu skizzieren. Darauf aufbauend sollen Perspektiven entwickelt werden, wie eine zukunftsfähige informationstechnologische Infrastruktur für Kreditinstitute gestaltet werden kann. Zu diesem Zweck wird ein Vorgehensmodell präsentiert, das den erforderlichen Transformationsprozeß unterstützen soll

Efficiency and profitability of European banks: how important is operational efficiency?

Most previous research on efficiency in banking takes a regulatory perspective. In contrast, this paper investigates the empirical relation between efficiency and profitability in five large economies of the European Union during the period 1998-2005 and discusses the results from the perspective of corporate bank strategy. Methodologically the existing literature is expanded by the use of DEA super-efficiency values to regress profitability, the incorporation of risk by calculative costs of capital, and a model specification built on the modern understanding of banks as centers of value creation. The results of the conducted static and dynamic regression analyses show that profitable banks operate with higher technical efficiency than their competitors. Furthermore, the strategic environment and in this regard the structure and concentration of the national financial sector have a considerable impact on a bank's financial performance. Both issues proved to be statistically and economically significant. Thus, the results support the appropriateness of the generic strategy of cost leadership for the European banking market. Banks following this strategic position were able to achieve higher excess returns during the analyzed period. --Banks,corporate strategy,efficiency,operational efficiency,profitability

Wandel im Gesundheitswesen: Analyse der Auswirkungen auf Ärzte und Patienten am Beispiel der Ukraine

Background The health care sector is experiencing a drastic transition all over the world. This has an impact not only on the way hospitals, clinics, special-care homes etc. are organized, but also on patients, personnel and other stakeholders involved. The consequences of changes for both physicians and patients are investigated using a comprehensive health care reform in Ukraine as an example. Methods The analysis is based on empirical data collected from general physicians in 2 Ukrainian cities. Based on the Job Demands-Resources Model, we developed a set of hypotheses and tested them using the structural equation modelling technique. A total of 178 general physicians (81% of the approached population) participated in the study. Results Our investigation reveals a clear relationship between the organizational job demands (additional tasks, structural changes, new processes) and their psychological effects (e. g., burnout). The latter have a negative impact on cooperation of physicians in hospitals leading to lower patient satisfaction. Discussion and Conclusions Change in health care is inevitable. The example of Ukraine shows that openness of hospitals towards change reduces the probability of physicians’ burnout and, eventually, increases patient satisfaction. We strongly suggest applying the process management approach in order to increase openness to change, especially in turbulent times

Riftdalkoorts kan lang verborgen blijven

Riftdalkoorts komt nu in vrijwel heel Afrika voor. In 2000 dook de ziekte ook op in Jemen en Saoedie-Arabië. Noordelijker is het te koud voor het virus, maar dat is volgens viroloog Rob Moormann geen reden om achterover te leunen. Van blauwtong werd immers ook gedacht dat het in Nederland niet kon overleve

Ultrafast all-optical wavelength conversion in silicon waveguides using femtosecond pump-probe pulses

Experimental results on ultrafast all-optical wavelength conversion in silicon-on-insulator waveguides are presented. Red and blue shifts of 10nm have been observed in femtosecond pump-probe experiments. Alloptical switching and the importance of waveguide dispersion are discussed
