So schlicht erkl{\"a}rt sich die grundlegende und aktuelle Relevanz des Themas der Synchronisierung ebenso wie seine kulturtechnische und medienphilosophische Ausformung. Die aktuelle medientheoretische und medienhistorische Aufmerksamkeit f{\"u}r die Verfertigung der Gegenwart (deren wichtigste Operation diejenige der Synchronisierung ist), wie sie sich auch im Jahresthema 2012/2013 der Forschungen am Internationalen Kolleg f{\"u}r Kulturtechnikforschung und Medienphilosophie (IKKM) niedergeschlagen hat, reagiert auf eine spezifische zeitphilosophische Spannungslage, die sich im Anschluss an die strukturale und poststrukturale sowie die systemtheoretische Differenztheorie einerseits und an eher empirische, ph{\"a}nomenale, aber auch technikhistorisch und -theoretisch relevante Sachverhalte andererseits ergeben hat. Den ersten Pol dieser Spannung bildet die Dekonstruktion der Pr{\"a}senz, etwa, im Sinne Jacques Derridas, der Gleichzeitigkeit von Stimme und Ohr beim Sprechen, oder, im Sinne Deborah Eschs, der Live-{\"U}bertragung des Fernsehens. Den anderen Pol jedoch bilden die dennoch sich behauptenden ph{\"a}nomenalen und funktionalen Gleichzeitigkeitserfahrungen und -effekte. Sie umfassen etwa das Miterleben des Spielzuges im Sport, wie Hans Ulrich Gumbrecht es gefasst hat, und zahlreiche andere {\"a}sthetische, insbesondere erhabene Erfahrungen. Am anderen Ende der Skala geh{\"o}ren aber auch Prozesse wie die technische Einsteuerung und Abstimmung von Taktfrequenzen in Regelkreisen und {\"U}bertragungszusammenh{\"a}ngen zu den g{\"u}ltigen Formen effektiver Gleichzeitigkeit. Auch Verdichtungsvorg{\"a}nge wie die mehr oder weniger instantane, ereignisbezogene wie ereignisf{\"o}rmige Bildung und Aufl{\"o}sung von Publika sind derlei relevante Pr{\"a}senzeffekte. Die grundlegende Einsicht in die Gemachtheit und folglich Dekonstruierbarkeit der Gegenwart durch Synchronisierungs- und Desynchronisierungsoperationen jedenfalls widerstreitet nach medienwissenschaftlicher {\"U}berzeugung nicht ihrer Wirklichkeit im Sinne der Wirksamkeit - der lateinischen »actualitas«, als deren deutschsprachige Entsprechung die Scholastik des Mittelalters bei Meister Eckhart den Begriff der »Wirklichkeit« erst einf{\"u}hrte.}, subject = {Medienwissenschaft}, language = {de} } @periodical{OPUS4-4851, title = {Focus Producing Places}, volume = {2014}, number = {5.2014, Heft 1}, editor = {Engell, Lorenz and Siegert, Bernhard}, publisher = {Felix Meiner Verlag}, address = {Hamburg}, organization = {Internationales Kolleg f{\"u}r Kulturtechnikforschung und Medienphilosophie}, issn = {2366-0767}, doi = {10.28937/ZMK-5-1}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20240507-48519}, pages = {171}, abstract = {Producing places is a twofold topic. It can refer to places as sites that produce something, that are productive, that have operations unfold, or actions happen, or objects emerge. Or it can refer to the fabrication of places as specific entities themselves. With the extended availability and practicability of digital positioning, locating, and tracking systems, it has become evident that places are not just there, but that they are generated, that they are subject to mediatechnological operations and effects. Nonetheless, and at the same time, the aspect of places as being productive has also attracted considerable attention. Furthermore, in either perspective, a media-theoretical challenge has come up. It invests two different threads within the realm of conceptualizing not only space, but precisely place under conditions of media, both of them leading way back into the evolution of media societies and cultural technologies.}, subject = {Medienwissenschaft}, language = {de} } @article{AdamatzkySchubert, author = {Adamatzky, Andrew and Schubert, Theresa}, title = {Slime mold microfluidic logical gates}, series = {Materials Today}, journal = {Materials Today}, doi = {10.1016/j.mattod.2014.01.018}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170413-31168}, pages = {86 -- 91}, abstract = {We demonstrate how logical operations can be implemented in ensembles of protoplasmic tubes of acellular slime mold Physarum polycephalum.

In the refinement procedures, a robust error estimator based on the value of the least square residuals functional of the governing differential equations and its boundaries at nodal points is used which is inherently available from the MDLSM formulation and can efficiently identify the zones with higher numerical errors. The results are compared with the refinement procedures in the irreducible formulation of discrete least squares meshless (DLSM) method and show the accuracy and efficiency of the proposed procedures.

The considered prosthesis is fabricated from a functionally graded material (FGM) comprising a layer of a titanium alloy bonded to a layer of hydroxyapatite. The elastic modulus of the FGM was adjusted in the radial, longitudinal, and longitudinal-radial directions by altering the volume fraction gradient exponent. Four cases were studied, involving two different methods of anchoring the prosthesis to the spongy bone and two cases of applied loading. The results revealed that the FG prostheses provoked more SED to the bone. The FG prostheses carried less stress, while more stress was induced to the bone and cement. Meanwhile, less shear interface stress was stimulated to the prosthesis-bone interface in the noncemented FG prostheses. The cement-bone interface carried more stress compared to the prosthesis-cement interface. Stair climbing induced more harmful effects to the implanted femur components compared to the normal walking by causing more stress. Therefore, stress shielding, developed stresses, and interface stresses in the THR components could be adjusted through the controlling stiffness of the FG prosthesis by managing volume fraction gradient exponent.}, subject = {Finite-Elemente-Methode}, language = {en} } @phdthesis{Buchwald, author = {Buchwald, Anja}, title = {Der Einfluss des Kalziums auf die Kondensation von (Alumo-)Silikaten in alkali-aktivierten Bindern}, doi = {10.25643/bauhaus-universitaet.2104}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20140124-21046}, school = {Bauhaus-Universit{\"a}t Weimar}, pages = {35}, abstract = {Es werden geopolymere und alkali-aktivierte Bindemittel definiert und ihre prinzipiellen technischen und {\"o}kologischen Eigenschaften diskutiert.}, subject = {Bindemittel}, language = {de} } @phdthesis{Cervantes, author = {Cervantes, Juan}, title = {Liberal or coordinated Sustainability?

This makes it necessary to recover the critical thinking to analyze and understand the reality, thus overcoming the ideological barrier towards claiming that things can be otherwise. It is clear from this research that the discourse of sustainable development has unquestionably transformed the context and content of political activity in Europe. This discourse has exercised and obvious influence in the Governance processes, mainly because it has contributed to the introduction of a new political field, which was then promoted, either explicitly or implicitly by policy-makers, researchers on the field and practitioners during the last three decades. Though it may be bold to affirm that the discourse of sustainable development is the sole driver of these whole set of changes, there is no doubt that it has played a key part in the way in which the governance priorities have been handled in the European continent.}, language = {en} } @article{ChenSchwingKarlovšeketal., author = {Chen, Zhen and Schwing, Moritz and Karlovšek, Jurij and Wagner, Norman and Scheuermann, Alexander}, title = {Broadband Dielectric Measurement Methods for Soft Geomaterials: Coaxial Transmission Line Cell and Open-Ended Coaxial Probe}, series = {International Journal of Engineering and Technology}, volume = {2014}, journal = {International Journal of Engineering and Technology}, number = {volume 6, number 5}, doi = {10.7763/IJET.2014.V6.728}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20210408-43984}, pages = {373 -- 380}, abstract = {Broadband dielectric measurement methods based on vector network analyzer coupled with coaxial transmission line cell (CC) and open-ended coaxial probe (OC) are simply reviewed, by which the dielectric behaviors in the frequency range of 1 MHz to 3 GHz of two practical geomaterials are investigated.

The results are consistent with previous study on standardized compacted kaolin and suggest that the dielectric properties at frequencies below 100 MHz are not only a function of water content but also functions of other soil state parameters including dry density. The hydration process of a commercial grout is monitored in real time by using OC. It is found that the time dependent dielectric properties can accurately reveal the different stages of the hydration process.

Abandonment that followed the deindustrialization contributed to an estrangement, turning derelict industrial spaces and run-down factories into a ballast to conjure with. At present, industrial heritage management applies flexibility and creativity, partially overcoming the essentially traditional paradigm of heritage preservation. This approach permits sustainable conservation - utilization and integration of disused industrial constructs in the contemporary urban landscape. Being a part of the European cultural stock, industrial heritage is an exciting and unique setting from many perspectives. It is defined and consumed by many markets, ranging from the industrial heritage tourism to the market of special events and festivals. Reused industrial buildings and factories come into view as products of post-industrial societies, fitting to the Western post-industrial (consumer) culture, offering a field of activities that are at an interface between the industrial history and contemporary socio-cultural milieu. Alteration of values, growth of new roles and definitions of industrial heritage, generated by functional restructuring, is a subject which is often left behind the general discussion about sustainable conservation and adaptive reuse of industrial heritage. Yet, in the modified state, industrial heritage is very complex to understand and to define. By conducting a desk and a case study research of former industrial complexes - Leipziger Baumwollspinnerei and Mattatoio di Testaccio, this doctoral thesis aims to identify industrial heritage as a contemporary (post-industrial) concept. Observation of ideas, values and definitions that emerge as a consequence of the transformation and re-conceptualization of industrial heritage are intended to raise awareness and appreciation of industrial heritage in the full richness of its contemporary interpretation.}, subject = {Denkmal}, language = {en} }
