„Wenn ich es nicht tue, dann macht's ein anderer“ – Subjektwerdungen und Verantwortung

Poststructuralist theory focuses largely on describing how and why subjects reproduce the social conditions they have internalised. This is a deconstruction of the central idea of the Enlightenment, the human capacity for autonomous action. At the same time, however, it also denies all individuals any responsibility and ultimately leads criticism into a crisis. Pragmatist philosophy offers the possibility of determining the role of the mind in processes of becoming a subject without abandoning the achievements of the poststructuralist concept of subjectification. The concept of transaction describes how actors constitute each other as subjects within social situations. The relationships that arise through such processes depend, among other things, on the personalities of those people involved. Accordingly, it is possible to identify the responsibility of individuals to govern their social relations and personality development. Since these aspects can only be determined in localised individual cases, this offers a particularly suitable starting point for geographical critic.</p

Initial Multidisciplinary Design and Analysis Framework

Within the Supersonics (SUP) Project of the Fundamental Aeronautics Program (FAP), an initial multidisciplinary design & analysis framework has been developed. A set of low- and intermediate-fidelity discipline design and analysis codes were integrated within a multidisciplinary design and analysis framework and demonstrated on two challenging test cases. The first test case demonstrates an initial capability to design for low boom and performance. The second test case demonstrates rapid assessment of a well-characterized design. The current system has been shown to greatly increase the design and analysis speed and capability, and many future areas for development were identified. This work has established a state-of-the-art capability for immediate use by supersonic concept designers and systems analysts at NASA, while also providing a strong base to build upon for future releases as more multifidelity capabilities are developed and integrated

Review on computational methods for Lyapunov functions

Lyapunov functions are an essential tool in the stability analysis of dynamical systems, both in theory and applications. They provide sufficient conditions for the stability of equilibria or more general invariant sets, as well as for their basin of attraction. The necessity, i.e. the existence of Lyapunov functions, has been studied in converse theorems, however, they do not provide a general method to compute them. Because of their importance in stability analysis, numerous computational construction methods have been developed within the Engineering, Informatics, and Mathematics community. They cover different types of systems such as ordinary differential equations, switched systems, non-smooth systems, discrete-time systems etc., and employ di_erent methods such as series expansion, linear programming, linear matrix inequalities, collocation methods, algebraic methods, set-theoretic methods, and many others. This review brings these different methods together. First, the different types of systems, where Lyapunov functions are used, are briefly discussed. In the main part, the computational methods are presented, ordered by the type of method used to construct a Lyapunov function

Praxis ist mehr als Praktiken – Warum moderne Ärzte und spirituelle Heiler im Prinzip das Gleiche tun

The pragmatist concept of praxis involves more than conventionalised practices. It also regards performative dynamics which derive from the fact that practices actually never are enacted in an exemplary manner. Each and every execution of a practice always bears the chance of success but also the risk of failure. Furthermore, the execution of a practice can be fractured in many ways. As situations are always unique, a variety of different dynamics can evolve, each of which might lead to further events which in turn might even result in an alteration of the convention of the practice. Due to such performative dynamics, individuals might experience diverse qualities of emotions, insights, and practical skills that are not inherent to the practices. Those individuals who are engaged in practices thus develop not only an understanding of conventionalised practices (unversalities) but also personal attitudes towards and opinions about these practices (singularities). The example of medical practices in Botswana can function as a role model to illustrate this notion of praxis. A juxtaposition of modern and traditional medicine shows that analysing the way how such fields of practice are epistemologically founded helps us to understand why they are incommensurable

Integration of Propulsion-Airframe-Aeroacoustic Technologies and Design Concepts for a Quiet Blended-Wing-Body Transport

This paper summarizes the results of studies undertaken to investigate revolutionary propulsion-airframe configurations that have the potential to achieve significant noise reductions over present-day commercial transport aircraft. Using a 300 passenger Blended-Wing-Body (BWB) as a baseline, several alternative low-noise propulsion-airframe-aeroacoustic (PAA) technologies and design concepts were investigated both for their potential to reduce the overall BWB noise levels, and for their impact on the weight, performance, and cost of the vehicle. Two evaluation frameworks were implemented for the assessments. The first was a Multi-Attribute Decision Making (MADM) process that used a Pugh Evaluation Matrix coupled with the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). This process provided a qualitative evaluation of the PAA technologies and design concepts and ranked them based on how well they satisfied chosen design requirements. From the results of the evaluation, it was observed that almost all of the PAA concepts gave the BWB a noise benefit, but degraded its performance. The second evaluation framework involved both deterministic and probabilistic systems analyses that were performed on a down-selected number of BWB propulsion configurations incorporating the PAA technologies and design concepts. These configurations included embedded engines with Boundary Layer Ingesting Inlets, Distributed Exhaust Nozzles installed on podded engines, a High Aspect Ratio Rectangular Nozzle, Distributed Propulsion, and a fixed and retractable aft airframe extension. The systems analyses focused on the BWB performance impacts of each concept using the mission range as a measure of merit. Noise effects were also investigated when enough information was available for a tractable analysis. Some tentative conclusions were drawn from the results. One was that the Boundary Layer Ingesting Inlets provided improvements to the BWB's mission range, by increasing the propulsive efficiency at cruise, and therefore offered a means to offset performance penalties imposed by some of the advanced PAA configurations. It was also found that the podded Distributed Exhaust Nozzle configuration imposed high penalties on the mission range and the need for substantial synergistic performance enhancements from an advanced integration scheme was identified. The High Aspect Ratio Nozzle showed inconclusive noise results and posed significant integration difficulties. Distributed Propulsion, in general, imposed performance penalties but may offer some promise for noise reduction from jet-to-jet shielding effects. Finally, a retractable aft airframe extension provided excellent noise reduction for a modest decrease in range
