Especially for seasonal storage, power-to-gas can be a promising approach. Biologically produced methane from hydrogen produced from surplus electricity can be used to substitute natural gas in the existing infrastructure. Current reactor types are not or are poorly optimized for flexible methanation. Therefore, this work proposes a new reactor type with a plug flow reactor (PFR) design. Simulations in COMSOL Multiphysics ® showed promising properties for operation in laminar flow. An experiment was conducted to support the simulation results and to determine the gas fraction of the novel reactor, which was measured to be 29\%. Based on these simulations and experimental results, the reactor was constructed as a 14 m long, 50 mm diameter tube with a meandering orientation. Data processing was established, and a step experiment was performed. In addition, a kLa of 1 h-1 was determined. The results revealed that the experimental outcomes of the type of flow and gas fractions are in line with the theoretical simulation. The new design shows promising properties for flexible methanation and will be tested.}, language = {en} } @article{KuertenMottaghyZiegler2015, author = {K{\"u}rten, Sylvia and Mottaghy, Darius and Ziegler, Martin}, title = {Design of plane energy geostructures based on laboratory tests and numerical modelling}, series = {Energy and Buildings}, volume = {107}, journal = {Energy and Buildings}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0378-7788}, doi = {10.1016/j.enbuild.2015.08.039}, pages = {434 -- 444}, year = {2015}, language = {en} } @article{RochefortVerverGrunendahletal.2005, author = {Rochefort, E. de and Verver, M. and Grunendahl, A. and Mooi, H. and Butenweg, Christoph}, title = {Detailed modelling of the lumbar spine for investigations of low back pain}, series = {SAE transactions : papers presented at Society and Section meetings / Society of Automotive Engineers}, volume = {Volume 114}, journal = {SAE transactions : papers presented at Society and Section meetings / Society of Automotive Engineers}, number = {Part 7}, organization = {Society of Automotive Engineers}, issn = {0096-736X}, pages = {788 -- 796}, year = {2005}, language = {en} } @article{KernSchelthoffMathieu2011, author = {Kern, Alexander and Schelthoff, Christof and Mathieu, Moritz}, title = {Detaillierte Berechnung der Einfangwirksamkeiten von Fangeinrichtungen mit einem dynamischen elektro-geometrischen Modell - Detailed calculation of the interception efficiencies for airtermination systems using a dynamic electro-geometrical model}, pages = {1 -- 5}, year = {2011}, language = {de} } @article{HelsperMoelter1987, author = {Helsper, Christoph and M{\"o}lter, W.}, title = {Determination and Neutralization of the Charge Produced by the Dispersion of Powders}, series = {Journal of Aerosol Science. 18 (1987), H. 6}, journal = {Journal of Aerosol Science. 18 (1987), H. 6}, isbn = {0021-8502}, pages = {877 -- 880}, year = {1987}, language = {de} } @article{HelsperFissanThielen1983, author = {Helsper, Christoph and Fißan, H.

We derive the phase mask from a Gerchberg-Saxton-type algorithm as an array and create each individual phase shift using a refractive index modification of variable axial length. We realize the variable axial length by superimposing refractive index modifications induced by an ultra-short pulsed laser at different focusing depth. Each single modification is created by applying 1000 pulses with 15 μJ pulse energy at 100 kHz to a fixed spot of 25 μm diameter and the focus is then shifted axially in steps of 10 μm. With several proof-of-principle examples, we show the feasibility of our method. In particular, we identify the induced refractive index change to about a value of Δn=1.5⋅10-3. We also determine our current limitations by calculating the overlap in the form of a scalar product and we discuss possible future improvements.}, language = {en} } @article{BreitbachPenkallaSchubert1989, author = {Breitbach, Gerd and Penkalla, H.-J. and Schubert, F.}, title = {Diskussion eines neuen ORNL-Stoffgesetzes fuer Inconel 617 / H.-J.

Researchers explore the fine details of why diversity management is central for generating innovations in heterogeneous research groups and how it could be effectively implemented into organizations. Complex research associations that discuss topics with a high impact on society increasingly address the necessity of establishing a diverse workforce to confront the challenges of tomorrow. Characterized by complex management structures as well as hierarchies, research associations have not been a subject of investigation until now. For this reason, the presented research project aims to develop a diversity and innovation management strategy with the ultimate goal of inducing change in the corporate culture. The proposed approach consisted of six phases; the first two phases investigated the status quo of diversity in the existing organizational structures of member institutes and the variety of particular working cultures within the research association. The third and the fourth phases utilized qualitative and quantitative studies. The third phase focused on the connection of management level to diversity and innovation, and the need for diversity and innovation management, and tailor-made methods of implementing them. The first three phases have been accomplished successfully; preliminary results are already available. The fourth phase will mainly focus on exploring the mind-set of the employees. The fifth phase will consolidate the findings in the first four phases into an implementable strategy. The final phase will address the implementation of this strategy into the organization.

The protection of the environment and the health of the population is the highest priority of our society. For the transport companies that operate these buses, not only ecological issues but also economic issues are of great importance. Due to the high purchase costs of electric buses compared to conventional buses, operators are forced to use electric vehicles in a targeted manner in order to ensure amortization over the service life of the vehicles. A compromise between ecology and economy must be found in order to both protect the environment and ensure economical operation of the buses. In this study, we present a new methodology for optimizing the vehicles' charging time as a function of the parameters CO₂eq emissions and electricity costs. Based on recorded driving profiles in daily bus operation, the energy demands of conventional and electric buses are calculated for the passenger transportation in the city of Aachen in 2017. Different charging scenarios are defined to analyze the influence of the temporal variability of CO₂eq intensity and electricity price on the environmental impact and economy of the bus. For every individual day of a year, charging periods with the lowest and highest costs and emissions are identified and recommendations for daily bus operation are made. To enable both the ecological and economical operation of the bus, the parameters of electricity price and CO₂ are weighted differently, and several charging periods are proposed, taking into account the priorities previously set. A sensitivity analysis is carried out to evaluate the influence of selected parameters and to derive recommendations for improving the ecological and economic balance of the battery-powered electric vehicle. In all scenarios, the optimization of the charging period results in energy cost savings of a maximum of 13.6\% compared to charging at a fixed electricity price. The savings potential of CO₂eq emissions is similar, at 14.9\%. From an economic point of view, charging between 2 a.m. and 4 a.m. results in the lowest energy costs on average. The CO₂eq intensity is also low in this period, but midday charging leads to the largest savings in CO₂eq emissions. From a life cycle perspective, the electric bus is not economically competitive with the conventional bus. However, from an ecological point of view, the electric bus saves on average 37.5\% CO₂eq emissions over its service life compared to the diesel bus. The reduction potential is maximized if the electric vehicle exclusively consumes electricity from solar and wind power.}, language = {en} } @article{FoersterSchaepersKruegeretal.1995, author = {F{\"o}rster, Arnold and Sch{\"a}pers, T. and Kr{\"u}ger, M. and Appenzeller, J.}, title = {Effect of electron-electron interaction on hot ballistic electron beams / Th.
