An artificial vibrissa-like sensor for detection of flows. - In: Sensors - Basel : MDPI, ISSN 1424-8220, Volume 19 (2019), issue 18, 3892, Seite 1-16

In nature, there are several examples of sophisticated sensory systems to sense flows, e.g., the vibrissae of mammals. Seals can detect the flow of their prey, and rats are able to perceive the flow of surrounding air. The vibrissae are arranged around muzzle of an animal. A vibrissa consists of two major components: a shaft (infector) and a follicle-sinus complex (receptor), whereby the base of the shaft is supported by the follicle-sinus complex. The vibrissa shaft collects and transmits stimuli, e.g., flows, while the follicle-sinus complex transduces them for further processing. Beside detecting flows, the animals can also recognize the size of an object or determine the surface texture. Here, the combination of these functionalities in a single sensory system serves as paragon for artificial tactile sensors. The detection of flows becomes important regarding the measurement of flow characteristics, e.g., velocity, as well as the influence of the sensor during the scanning of objects. These aspects are closely related to each other, but, how can the characteristics of flow be represented by the signals at the base of a vibrissa shaft or by an artificial vibrissa-like sensor respectively? In this work, the structure of a natural vibrissa shaft is simplified to a slender, cylindrical/tapered elastic beam. The model is analyzed in simulation and experiment in order to identify the necessary observables to evaluate flows based on the quasi-static large deflection of the sensor shaft inside a steady, non-uniform, laminar, in-compressible flow.

Zoom systems with tunable lenses and linear lens movements. - In: Journal of the European Optical Society - London, ISSN 1990-2573, Volume 15 (2019), issue 1, article 9, Seite 1-10

Background: Classical zoom lenses are based on movements of sub-modules along the optical axis. Generally, a constant image plane position requires at least one nonlinear sub-module movement. This nonlinearity poses a challenge for the mechanical implementation. Tuneable lenses can change their focal length without moving along the optical axis. This offers the possibility of small system lengths. Since the focal range of tuneable lenses with significant aperture diameters is still limited, the use of tuneable optics in zoom lenses is usually restricted to miniaturized applications. Methods: To solve the challenge of the nonlinear movement in classical zoom lenses and the limitations of tuneable lenses for macroscopic applications we propose a combination of both concepts. The resulting 'Hybrid Zoom Lens' involves linear movements of sub modules as well as changing the focal length of a tuneable lens. The movements of the sub-modules and the focal length tuning of the lens are already determined by the collinear layout of the zoom lens. Therefore, we focus on collinear considerations and develop a method that allows a targeted choice of specific collinear layouts for our 'Hybrid zoom lenses'. Results: Based on examples and an experimental setup we demonstrate the feasibility of our approach. We apply the proposed method to examples of classical zoom lenses and zoom lenses based exclusively on tuneable lenses. Thereby we are able to show possible advantages of our 'Hybrid zoom lenses' over these widespread system types. Conclusions: We demonstrate important collinear considerations for the integration of tuneable lenses into a zoom lens. We show that the combination of classical zoom lens concepts with tuneable lenses offers the possibility to reach smaller system lengths for macroscopic zoom lenses while requiring only a small focal tuning range of the tuneable lens.

Modeling and design of flexure hinge-based compliant mechanisms. - In: Kinematics : analysis and applications. - London : InTechOpen, (2019), S. 1-24

A compliant mechanism gains its mobility fully or partially from the compliance of its elastically deformable parts rather than from conventional joints. Due to many advantages, in particular the smooth and repeatable motion, monolithic mechanisms with notch flexure hinges are state of the art in numerous precision engineering applications with required positioning accuracies in the low micrometer range. However, the deformation and especially motion behavior are complex and depend on the notch geometry. This complicates both the accurate modeling and purposeful design. Therefore, the chapter provides a survey of different methods for the general and simplified modeling of the elasto-kinematic properties of flexure hinges and compliant mechanisms for four hinge contours. Based on non-linear analytical calculations and FEM simulations, several guidelines like design graphs, design equations, design tools or a geometric scaling approach are presented. The obtained results are analytically and simulatively verified and show a good correlation. Using the example of a path-generating mechanism, it will be demonstrated that the suggested angle-based method for synthesizing a compliant mechanism with individually shaped hinges can be used to design high-precise and large-stroke compliant mechanisms. The approaches can be used for the accelerated synthesis of planar and spatial flexure hinge-based compliant mechanisms.

detasFLEX - a computational design tool for the analysis of various notch flexure hinges based on non-linear modeling. - In: Mechanical sciences : MS ; an open access journal for theoretical and applied mechanics. - Göttingen : Copernicus Publ., ISSN 2191-916X, Bd. 9 (2018), 2, S. 389-404

A novel computational design tool to calculate the elasto-kinematic flexure hinge properties is presented. Four hinge contours are implemented. It is shown, that FEM results correlate well with the analytical design tool results. For a given deflection angle of 10˚ and a corner-filleted contour, the deviations of the bending stiffness are between 0.1 % and 9.4 %. The design tool can be beneficial for the accelerated and systematic synthesis of compliant mechanisms with optimized flexure hinges.

Plasmonic nanosponges. - In: Advances in Physics: X : APX. - Abingdon : Taylor & Francis Group, ISSN 2374-6149, Bd. 3 (2018), 1, Article: 1456361, insges. 19 S.

Gold nanosponges, or nanoporous gold nanoparticles, possess a percolated nanoporous structure over the entire nanoparticles. The optical and plasmonic properties of gold nanosponges and its related hybrid nanosponges are very fascinating due to the unique structural feature, and are controllable and tuneable in a large scope by changing the structural parameters like pore/ligament size, porosity, particle size, particles form, and hybrid structure. The nanosponges show the strong polarization dependence and multiple resonances behavior. Besides, the nanosponges exhibit a significantly higher local field enhancement than the solid nanoparticles. Strong nonlinear optical properties are confirmed by their high-order photoemission behavior, whereby long-lived plasmon modes are also clearly observed. All this is very important and relevant for the applications in enhanced Raman scattering, fluorescence manipulation, sensing, and nonlinear photonics.

Subjective evaluation of media content as a moderator of media effects on European identity: mere exposure and the hostile media phenomenon. - In: Media and Communication - Basel : Librello Publishing House, Bd. 5 (2017), 2, S. 41-52

This paper posits that the concept of European identity is an important indicator of the legitimacy of the European Union (EU). It further assumes that the exposure to EU related media content can influence the feeling of European identity. In order to verify this assumption, we combined the mere-exposure-theory and the hostile media phenomenon. We assume that these theoretical concepts could help to understand the influence of media on peoples levels of attachment to the EU. Regression analyses are performed on secondary data that were collected in a Eurobarometer survey in 2013. Our findings revealed that media exposure affected the respondents' identification with Europe, as well as the modifications of this effect based on their assessments of EU media coverage. The results of the current study not only validate assumptions about the mere-exposure effects on identity but also confirm the theoretical assumption that perceived hostility reduces such effects, whereas exposure to information that is perceived as neutral promotes the effects of media exposure on the feeling of European identity.

General design equations for the rotational stiffness, maximal angular deflection and rotational precision of various notch flexure hinges. - In: Mechanical sciences : MS ; an open access journal for theoretical and applied mechanics. - Göttingen : Copernicus Publ., ISSN 2191-916X, Bd. 8 (2017), 1, S. 29-49

Notch flexure hinges are often used as revolute joints in high-precise compliant mechanisms, but their contour-dependent deformation and motion behaviour is currently difficult to predict. This paper presents general design equations for the calculation of the rotational stiffness, maximal angular elastic deflection and rotational precision of various notch flexure hinges in dependence of the geometric hinge parameters. The novel equations are obtained on the basis of a non-linear analytical model for a moment and a transverse force loaded beam with a variable contour height. Four flexure hinge contours are investigated, the semi-circular, the corner-filleted, the elliptical, and the recently introduced bi-quadratic polynomial contour. Depending on the contour, the error of the calculated results is in the range of less than 2 % to less than 16 % for the suggested parameter range compared with the analytical solution. Finite elements method (FEM) and experimental results correlate well with the predictions based on the comparatively simple and concise design equations.

Laser-based joining of thermoplastics to metals: influence of varied ambient conditions on joint performance and microstructure. - In: International journal of polymer science - New York, NY : Hindawi, ISSN 1687-9430, (2016), Article ID 5301081, insges. 9 S.

Laser-based joining of thermoplastics to metals shows a great potential for functional design especially in terms of lightweight constructions. In the joining process, the joining speed and the energy per unit length, respectively, show an influence on time-temperature profiles measured in the joining zone. The time-temperature profile affects the joining zone and consequently the joint behavior in mechanical testing. In the current investigation, the joining zone was characterized by the melting layer. Moreover, the mechanical properties of the joint by tensile shear testing and the fracture mode were investigated. Based on the results obtained, three sets of joining speeds/energies per unit length with different mechanical behaviors were selected for further investigations under varied ambient conditions. Thereby, the influence of outdoor weathering as well as aging above the glass transition temperature of the plastic part on the joints performance was compared with the nonaged joints.

Introducing a method for modeling knowledge bases in expert systems using the example of large software development projects. - In: International Journal of Advanced Computer Science and Applications : IJACSA. - New York, NY, ISSN 2156-5570, Bd. 6.2015, 12, Paper 1, S. 1-7

Goal of this paper is to develop a meta-model, which provides the basis for developing highly scalable artificial intelligence systems that should be able to make autonomously decisions based on different dynamic and specific influences. An artificial neural network builds the entry point for developing a multi-layered human readable model that serves as knowledge base and can be used for further investigations in deductive and inductive reasoning. A graph-theoretical consideration gives a detailed view into the model structure. In addition to it the model is introduced using the example of large software development projects. The integration of Constraints and Deductive Reasoning Element Pruning are illustrated, which are required for executing deductive reasoning efficiently.

Categorizing terrorist entities listed by the European Union, according to terrorist groups' underlying motives. - In: Conflict & communication online - Berlin : Regener, ISSN 16180747, Bd. 14 (2015), 2, S. 1-14

States and international organizations have compiled lists of a great variety of terrorist groups. The current European Union list includes 44 entities. This study analyzes the underlying motives of the terrorist organizations named in this list. In order to understand the groups' motivations and consequently be able to advise on methods of countering them with communication strategies, we employ a three-item typology provided by Waldmann (2001). The results show that only five of the 44 groups were religiously motivated to commit terrorism. Most of the groups (n=20) had nationalist-separatist motives, and 19 groups displayed social-revolutionary motives. Based on the respective motives, differing counter-terrorism strategies are proposed, e.g., developing rhetorical counter-narratives that address and reduce the groups' motivational and identity-generating characteristics.
