The FH Aachen - Aachen University of Applied science is one of the biggest Fachhochschulen in Germany with roughly 11,300 students, 220 professors, 300 contract lecturers, and 340 assistants. It is specialized in certain topical areas . It must not be confused with the RWTH Aachen, which is also located in Aachen. FH Aachen ranks as the first best among the universities of Applied science in Germany in the fields of Electrical and Mechanical engineering. Ten Faculties offer 48 Bachelor's, 22 Master's and three cooperative degree programmes. In 2011 the external and research funding added up to 12,2 million Euro. The FH Aachen is situated in Aachen and in Jülich. Wikipedia.

Temperature sensing is essential for the survival of living organisms. Since thermal gradients are almost everywhere, thermoreception could represent one of the oldest sensory transduction processes that evolved in organisms. There are many examples of temperature changes affecting the physiology of living cells. Almost all classes of biological macromolecules in a cell (nucleic acids, lipids, proteins) can serve as a target of the temperature-related stimuli. This review is devoted to some common features of different classes of temperature-sensing molecules as well as molecular and biological processes involved in thermosensation. Biochemical, structural and thermodynamic approaches are discussed in order to overview the existing knowledge on molecular mechanisms of thermosensation. © 2011 Springer Science+Business Media B.V.

The concept of an injective affine embedding of the quantum states into a set of classical states, i.e., into the set of the probability measures on some measurable space, as well as its relation to statistically complete observables is revisited, and its limitation in view of a classical reformulation of the statistical scheme of quantum mechanics is discussed. In particular, on the basis of a theorem concerning a nondenseness property of a set of coexistent effects, it is shown that an injective classical embedding of the quantum states cannot be supplemented by an at least approximate classical description of the quantum mechanical effects. As an alternative approach, the concept of quasi-probability representations of quantum mechanics is considered. © 2014 AIP Publishing LLC. Source

Structural reliability analysis is based on the concept of a limit state function separating failure from safe states of a structure. Upper and lower bound theorems of limit and shakedown analysis are used for a direct definition of the limit state function for failure by plastic collapse or by inadaptation. Shakedown describes an asymptotic and therefore time invariant structural behavior under time variant loading. The limit state function and its gradient are obtained from a mathematical optimization problem. The method is implemented into a general purpose finite element model (FEM) code. Combined with first-order methods/second-order methods (FORM/SORM) robust and precise analyses can be performed for structures with high reliability. This approach is particularly effective because the sensitivities which are needed by FORM/SORM are derived from the solution of the deterministic problem. © 2014 World Scientific Publishing Company.

Stepped spillways are known to enhance the energy dissipation potential when compared with common smooth invert chutes. In the skimming flow regime, the self-aerated flow becomes more chaotic and surface waves (referred to as air-water surface roughness) are enhanced when the discharge decreases. In this study, experiments on smooth invert and stepped chutes models with a slope of 1: 2 were conducted to characterize this surface roughness by the use of a high-speed camera and ultrasonic sensor. It was found that the amount of entrapped air - at the water level where the air concentration is 90% - is reduced when a stepped spillway is considered. With decrease in step height (and on smooth invert chutes), entrapped air became more relevant. Wave heights increased with increase in step height and exceeded significantly the characteristic water level with 90% air concentration which was detected by a conductivity probe. A wide range of wave frequencies indicated the turbulent structure of stepped spillway flows. © 2013 Copyright International Association for Hydro-Environment Engineering and Research. Source

CIVITAS-DYN@MO is an ambitious project with strategic importance to sustainable mobility planning in four dynamic European cities. Aachen (DE), Gdynia (PL), Koprivnica (HR) and Palma (ES) will jointly develop Mobility 2.0 systems and services, implement city and citizen-friendly, electric mobility solutions and vehicles, and engage in a dynamic citizen dialogue for mobility planning and service improvement. CIVITAS-DYN@MO is targeting dynamic citizens, and especially the digital natives in response to an emerging new mobility paradigm. A considerable part of the younger population in the DYN@MO university cities will be challenged to use web 2.0 apps to find appropriate means of travelling within the city and to communicate with PT operators. A sound basis for mobility planning is a citizen-centred Sustainable Urban Transport Plan. The two leading cities Aachen and Gdynia will advance their planning culture, while Koprivnica and Palma will develop ambitious sustainable urban transport plans all involving extensively citizens and stakeholders via web2.0 applications. Clean public transport remains the backbone of urban transport systems, and the cities have strong commitment to enhance the environmental performance and energy efficiency of their fleets. Alternative fuels, such as CNG and hybrid buses, and the increased use of electromobility in public transport and car sharing schemes will help to accelerate the introduction of clean vehicles in the European market. Venturing in new technology and mobility options as well as promoting new life styles will increase the peoples acceptance for mobility without a private car. The cities propose complementing packages with a high degree of transferability across Europe. Profound evaluation and research with strong dissemination and mutual learning through SUTP Competence Centres will strengthen the strategic impact of the project.
