The sound spatialization framework of the University of Aizu, which supports number of spatialization backends, has been extended to include a sound spatialization server for a multichannel loudspeaker array (Pioneer Sound Field Control System). Our goal is that the spatialization server allows easy integration into virtual environments. Modeling of distance cues, which are essential for full immersion, is discussed. Furthermore, the integration of this prototype into different applications allowed us to reveal the advantages and problems of spatial sound for virtual reality environments.}, language = {en} } @phdthesis{Herder1999, author = {Herder, Jens}, title = {A Sound Spatialization Resource Management Framework}, publisher = {University of Tsukuba}, address = {Tsukuba}, organization = {University of Tsukuba}, year = {1999}, abstract = {In a virtual reality environment, users are immersed in a scene with objects which might produce sound. The responsibility of a VR environment is to present these objects, but a practical system has only limited resources, including spatialization channels (mixels), MIDI/audio channels, and processing power. A sound spatialization resource manager, introduced in this thesis, controls sound resources and optimizes fidelity (presence) under given conditions, using a priority scheme based on psychoacoustics. Objects which are spatially close together can be coalesced by a novel clustering algorithm, which considers listener localization errors. Application programmers and VR scene designers are freed from the burden of assigning mixels and predicting sound source locations. The framework includes an abstract interface for sound spatialization backends, an API for the VR environments, and multimedia authoring tools.}, language = {en} } @inproceedings{BackesFaberAnthrakidisetal.2008, author = {Backes, Klaus and Faber, Christian and Anthrakidis, Anette and Ille, Fabian and Adam, Mario and Schramm, Sebastian}, title = {A small scale Combined Cooling, Heating and Power System}, series = {World Renewable Energy Congress X and Exhibition, 19-25.07.2008, Glasgow}, booktitle = {World Renewable Energy Congress X and Exhibition, 19-25.07.2008, Glasgow}, editor = {WREN,}, address = {Glasgow}, year = {2008}, language = {en} } @article{FallingKaluzaStrucks2021, author = {Falling, Luisa and Kaluza, Stefan and Strucks, Peter}, title = {A Short Review on Ni-Catalyzed Methanation of CO²: Reaction Mechanism, Catalyst Deactivation, Dynamic Operation}, series = {Chemie Ingenieur Technik}, volume = {93}, journal = {Chemie Ingenieur Technik}, publisher = {Wiley}, issn = {1522-2640}, doi = {10.1002/cite.202100049}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-32134}, pages = {1526 -- 1536}, year = {2021}, abstract = {Today, the use of renewable energies and recycling of climate-changing gases are increasingly important. In this context,coupling of methanation with small, decentralized CO2sources such as biogas plants provides one possibility. However,fluctuating availability of renewables for hydrogen production in combination with small storage volumes result in anenhanced demand for dynamic process operation. This leads to new research challenges with respect to the required cata-lysts and the overall process design. To draw reliable conclusions about the catalytic performance under dynamic processoperation, the mechanism of the methanation reaction as well as typical deactivation procedures of the catalyst appliedunder steady-state conditions have to be reviewed thoroughly.}, language = {en} } @inproceedings{HateburHeiselSchmidt2007, author = {Hatebur, Denis and Heisel, Maritta and Schmidt, Holger}, title = {A Security Engineering Process based on Patterns}, series = {18th International Workshop on Database and Expert Systems Applications (DEXA 2007)}, booktitle = {18th International Workshop on Database and Expert Systems Applications (DEXA 2007)}, publisher = {IEEE}, address = {Regensburg}, isbn = {978-0-7695-2932-5}, doi = {10.1109/DEXA.2007.36}, pages = {734 -- 738}, year = {2007}, abstract = {We present a security engineering process based on security problem frames and concretized security problem frames.
