"Forschung fördern, Lehre entwickeln, Versorgung stärken - für die Zukunft der Physiotherapie" war das Motto des 5. Forschungssymposiums Physiotherapie, welches durch die Brandenburgische Technische Universität Cottbus-Senftenberg (BTU) und die Deutsche Gesellschaft für Physiotherapiewissenschaft e. V. (DGPTW) am 26. und 27.11.2021 veranstaltet wurde.
Im Abstractband des 5. Forschungssymposiums Physiotherapie sind die Abstracts der eingereichten und beim 5. Forschungssymposiums Physiotherapie präsentierten Beiträge veröffentlicht. Zudem sind die veranstalteten Workshops zusammenfassend dargestellt.
High Medieval chimneys, although often the focal point of contemporary representative buildings, are rarely a topic of construction history. More often they appear in art or architectural history where they are discussed regarding their style and ornamentation. It is however worthwhile to examine these important representative objects with the tools of the construction historian. In them, we can find important information regarding the contemporary craftsmanship and skills. Based on extensive firsthand examinations and building archaeology this paper aims to discuss the planning and building process of the highly complex cut-stone chimney system in the keep of Schönburg Castle (1201 CE) using new methods of reverse engineering.
1. Memristor-Symposium 2023
(2023)
The 1.Memristor-Symposium was held from 27-28.02.2023 in Bamberg. Young scientists and PhD students presented their research and covered several topics regarding ongoing memristive research in Germany. Several talks on the topic of memristive devices, their testing, modeling and usage were presented and discussed, covering the whole vertical integration from material and divice up to application level.
There are many names we use to call them, like the (original) Wireless Sensor Networks, Wireless Sensor and Actuator Networks, Internet of Things, Cyber-Physical Systems, Cyber-Physical Systems of Systems, and some others. More or less visible, wireless sensor networks are already applied in many aspects of our lives and for different purposes. During the 20 years of Fachgespräch Sensornetze (FGSN) we were able to observe the process of the birth and evolution of wireless sensor networks. What do they look like now, from that time perspective? Is there still room for research andimprovements? Or are they maybe already that mature that everything has already been said? And what do they look like from the industry point of view? What is the future of sensor networks? Where are they heading? These retrospective and perspective views are the central topic of the 20th edition of the Fachgespräch Sensornetze (FGSN 2023) held on the 4th of September 2023 at Hasso-Plattner-Institut as part of the NetSys 2023 conference in Potsdam. We were happy to meet again, to discuss these subjects within the scientific community. The aim of this series of Fachgespräch is to give scientists from academia and industry the opportunity for an informal exchange of ideas and to strengthen cooperation in this multidisciplinary research area.
Die Geoarchäologie ist ein noch sehr junges, interdisziplinäres Feld in der Wissenschaftslandschaft. Umso erfreulicher ist das steigende Interesse an diesem Bereich. Diese Beliebtheit zeigt sich auch durch die stetig zunehmenden Beitragsmeldungen bei den Jahrestagungen des AK Geoarchäologie. Zudem finden Sessions zur Geoarchäologie bei nationalen und internationalen archäologischen und geowissenschaftlichen Konferenzen großen Zuspruch.
Viele Mitglieder des AK Geoarchäologie gestalten diese Konferenz aktiv mit ihren Beiträgen. Vorträge und Posterpräsentationen, Exkursionen und nicht zuletzt persönliche Gespräche sind essentielle Grundlage für den wissenschaftlichen Austausch.
Vom 2. bis 4.Mai 2013 richten die Brandenburgische Technische Universität Cottbus (BTU), das Brandenburgische Landesamt für Denkmalpflege und Archäologische Landesmuseum (BLDAM) und das Landesamt für Bergbau, Geologie und Rohstoffe (LBGR) des Landes Brandenburg die neunte Jahrestagung des AK Geoarchäologie aus. Wir freuen uns sehr, dass unserer Einladung nach Cottbus mehr als 90 Wissenschaftlerinnen und Wissenschaftler sowie Vertreter von Behörden, Kommunen und Wirtschaftsunternehmen gefolgt sind.
26 Vortrags- und 31 Postermeldungen konnten berücksichtigt werden, und die Exkursion in den Tagebau Jänschwalde ist mit 60 Teilnehmern ausgebucht. Wir hoffen, dass unser Treffen in Cottbus einen Beitrag zur Stärkung und Weiterentwicklung der Geoarchäologie in Deutschland leisten kann. In diesem Sinne möchten wir mit dem vorliegenden Tagungsband auch eine Handreichung für die wissenschaftliche Nachbereitung geben.
Unser Dank gilt allen Teilnehmerinnen und Teilnehmern sowie den zahlreichen Helferinnen und Helfern aus den ausrichtenden Institutionen, die bei der Vorbereitung der Tagung aktiv waren. Wir wünschen der Tagung ein gutes Gelingen und zahlreiche anregende Diskussionen.
Nostocales form thick-walled, resting cells (akinetes) for overwintering in lake sediments of Central Europe. The pelagic Nostocales population recruits after the germination of akinetes, which mainly takes place in the spring with increasing temperatures and light intensities. The study aimed to i) characterize the sediment surfaces inhabited by viable akinetes that potentially contribute to the formation of a pelagic population, and ii) estimate the inoculum size of the available sedimentary akinete pool. We investigated the horizontal distribution of akinetes in sediments and the seasonal course of light and temperature in two deep dimictic lakes (Lake Stechlinsee, max. depth 69 m and Lake Scharmützelsee, max. depth 29.5 m; NE Germany). The akinete pool was calculated and the potential inoculum was estimated using assumed light and temperature data for akinete germination. The akinete abundance in sediments depended on the basin morphometry and increased with water depth. Only a small proportion of the viable akinete pool in shallow water areas contributed as inoculum to pelagic population. The potential inoculum size in Lake Scharmützelsee was larger than in Lake Stechlinsee.
Vortrag “ICESP XIV. International Conference on Electrostatic Precipitation 2016”, Wroclaw, Polen, 19.-23.09.2016
Back corona and dust resistivity are well known topics in electrostatic precipitation. Back corona results from high dust resistivity and occurs when the field strength in the dust layer surpasses a critical value E crit, which is typically found to be in the order of 15 to 30 kV/cm. Besides the resistivity ρ, the current density is the main parameter: E = i ρ < E crit. Hence, possible actions against back corona include a reduction of ρ by dust conditioning, or a reduction of i, for example by pulsed corona operation.
Much work has been devoted to study the dependence of ρ on dust composition, temperature, humidity, adsorption layers and dust layer porosity, and a variety of different set-ups for dust resistivity measurements has been proposed. Even though some authors report a dependence of ρ on current density or field strength resp., dust resistivity is mostly seen as a material property.
However, in measurements on product dusts in the upper resistivity range, we found that dusts show extremely non-ohmic properties:
Most strikingly, resistivity may vary by several orders of magnitude with time.
Also, the experimental arrangement can change the resistivity results by orders of magnitude: When resistivity is measured with the dust layer exposed to a corona discharge (imitating the situation in a real ESP), ρ depends strongly on the layer thickness. Meanwhile the same dust does not show the strong layer thickness dependence when electrodes are placed on both sides of the dust layer, and also time effects are much less prominent.
Additional findings include that dusts that have been exposed to resistivity measurements show a high level of electrostatic charging afterwards.
An interpretation of these results may be found from the theory of semiconductors and electret materials. Accordingly, highly resistive dust layers do not contain mobile electrons. Current transport occurs only after charge carriers (free electrons or holes) have been injected from the electrodes or from a gas discharge adjacent to the surface.
When the injection process is non-symmetric (e.g. with corona discharge), the current transport through the dust layer can be dominated by charge carriers of one polarity, depending on the polarity of the corona. Some of the effects observed in experiment, namely the layer thickness effect and the current density influence, can indeed be ascribed to unipolar injection and space charge limited conduction.
The time effects can mainly be ascribed to the “deep trapping” of the charge carriers, leading to a high level of immobile space charge. As overall space charge is limited, this reduces the level of mobile space charge available for current transport. The space charge also leads to a deformation of the electric field inside the dust layer, and hence influences injection via the Schottky (thermionic field emission) mechanism.
By integrating the mechanisms of charge transport in dielectrics (injection, drift, immobilization, recombination) into the OpenFOAM® simulation package, rather realistic simulations of time-dependent resistivity are possible. The simulations also are helpful to identify the mechanisms responsible for certain types of resistivity behavior.
The tiny logic elements in modern integrated circuits increase the rate of transient failures significantly. Therefore, redundancy on various levels is necessary to retain reliability. However, for mixed-criticality scenarios, the typical processor designs offer either too little fault-tolerance or too much redundancy for one part of the applications. Amongst others, we specifically address redundant processor internal functional units (FU) to cope with transient errors and support wear leveling. A real-time operating system (RTOS) was extended to control our prototypical hardware platform and, since it can be configured deterministically within few clock cycles, we are able to reconfigure the FUs dynamically, at process switching time, according to the specified critically of the running processes. Our mechanisms were integrated into the Plasma processor and the Plasma-RTOS. With few changes to the original software code, it was, for example, possible to quickly change from fault-detecting to fault-correcting modes of the processor on demand.
The ongoing and unprecedented transformation of power systems leads to a reduction in the number of conventional power plants, which are the classical actuators of the grid. In addition, this development results in a decreasing system inertia, which is expected to yield faster frequency dynamics. Therefore power-electronics-interfaced units have to take over system control tasks and, in particular, frequency control. For this purpose, accurate and fast estimation algorithms for time-varying frequency signals are needed. Motivated by this fact, we propose a time-varying parameter estimator and a tuning criterion, which for sufficiently small initial estimation errors allows to reconstruct the time-varying frequency signal of a symmetric three-phase waveform in finite time. The proposed estimator is derived by using a time-varying version of the super twisting algorithm and its performance is illustrated via numerical examples.
