@inproceedings{DuranParedesMottaghyHerrmannetal.2020, author = {Duran Paredes, Ludwin and Mottaghy, Darius and Herrmann, Ulf and Groß, Rolf Fritz}, title = {Online ground temperature and soil moisture monitoring of a shallow geothermal system with non-conventional components}, series = {EGU General Assembly 2020}, booktitle = {EGU General Assembly 2020}, year = {2020}, abstract = {We present first results from a newly developed monitoring station for a closed loop geothermal heat pump test installation at our campus, consisting of helix coils and plate heat exchangers, as well as an ice-store system. There are more than 40 temperature sensors and several soil moisture content sensors distributed around the system, allowing a detailed monitoring under different operating conditions.In the view of the modern development of renewable energies along with the newly concepts known as Internet of Things and Industry 4.0 (high-tech strategy from the German government), we created a user-friendly web application, which will connect the things (sensors) with the open network (www). Besides other advantages, this allows a continuous remote monitoring of the data from the numerous sensors at an arbitrary sampling rate.Based on the recorded data, we will also present first results from numerical simulations, taking into account all relevant heat transport processes.The aim is to improve the understanding of these processes and their influence on the thermal behavior of shallow geothermal systems in the unsaturated zone. This will in turn facilitate the prediction of the performance of these systems and therefore yield an improvement in their dimensioning when designing a specific shallow geothermal installation.}, language = {en} } @article{DuttaHartkopfFroederWitteetal.2013, author = {Dutta, Suryendu and Hartkopf-Fr{\"o}der, Christoph and Witte, Karin and Brocke, Rainer and Mann, Ulrich}, title = {Molecular characterization of fossil palynomorphs by transmission micro-FTIR spectroscopy: implications for hydrocarbon source evaluation}, series = {International journal of coal geology}, volume = {Vol. 115}, journal = {International journal of coal geology}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1872-7840 (E-Journal); 0166-5162 (Print)}, pages = {13 -- 23}, year = {2013}, language = {en} } @incollection{DuweTippkoetterUlber2018, author = {Duwe, A. and Tippk{\"o}tter, Nils and Ulber, R.}, title = {Lignocellulose-Biorefinery: Ethanol-Focused}, series = {Biorefineries}, booktitle = {Biorefineries}, publisher = {Springer}, address = {Cham}, doi = {10.1007/10_2016_72}, pages = {177 -- 215}, year = {2018}, abstract = {The development prospects of the world markets for petroleum and other liquid fuels are diverse and partly contradictory. However, comprehensive changes for the energy supply of the future are essential. Notwithstanding the fact that there are still very large deposits of energy resources from a geological point of view, the finite nature of conventional oil reserves is indisputable. To reduce our dependence on oil, the EU, the USA, and other major economic zones rely on energy diversification. For this purpose, alternative materials and technologies are being sought, and is most obvious in the transport sector. The objective is to progressively replace fossil fuels with renewable and more sustainable fuels. In this respect, biofuels have a pre-eminent position in terms of their capability of blending with fossil fuels and being usable in existing cars without substantial modification. Ethanol can be considered as the primary renewable liquid fuel. In this chapter enzymes, micro-organisms, and processes for ethanol production based on renewable resources are described.}, language = {en} } @inproceedings{DyllaFerreinLakemeyer2003, author = {Dylla, Frank and Ferrein, Alexander and Lakemeyer, Gerhard}, title = {AllemaniACs 2003 team description}, series = {RoboCup 2003 : Robot Soccer World Cup VII}, booktitle = {RoboCup 2003 : Robot Soccer World Cup VII}, pages = {1 -- 3}, year = {2003}, language = {en} } @inproceedings{Doeren1988, author = {D{\"o}ren, Horst-Peter}, title = {The examination of surfaces of cold rolled wire for gas-shielded arc-welding}, series = {WAI/BISPA joint conference : proceedings.
