A depth image is computed by calculating the distortion of a known infrared light (IR) pattern which is projected into the scene. While these sensors are great devices they have some limitations. The distance they can measure is limited and they suffer from reflection problems on transparent, shiny, or very matte and absorbing objects. If more than one RGB-D camera is used the IR patterns interfere with each other. This results in a massive loss of depth information. In this paper, we present a simple and powerful method to overcome these problems. We propose a stereo RGB-D camera system which uses the pros of RGB-D cameras and combine them with the pros of stereo camera systems. The idea is to utilize the IR images of each two sensors as a stereo pair to generate a depth map. The IR patterns emitted by IR projectors are exploited here to enhance the dense stereo matching even if the observed objects or surfaces are texture-less or transparent. The resulting disparity map is then fused with the depth map offered by the RGB-D sensor to fill the regions and the holes that appear because of interference, or due to transparent or reflective objects. Our results show that the density of depth information is increased especially for transparent, shiny or matte objects.}, language = {en} } @incollection{Alt1971, author = {Alt, Helmut}, title = {Fußball oder Mathematik}, series = {Alma Mater Aquensis : Jahresbericht}, booktitle = {Alma Mater Aquensis : Jahresbericht}, pages = {110 -- 114}, year = {1971}, language = {de} } @incollection{Alt1983, author = {Alt, Helmut}, title = {Analog anzeigende Digitaluhr}, series = {FH-Texte ; 36 : Berichte aus dem Fachbereich Elektrotechnik Aachen}, booktitle = {FH-Texte ; 36 : Berichte aus dem Fachbereich Elektrotechnik Aachen}, publisher = {Fachhochschule Aachen}, address = {Aachen}, pages = {98 -- 104}, year = {1983}, language = {de} } @incollection{Alt2022, author = {Alt, Helmut}, title = {Speicher speichern, Leiter leiten}, series = {Generationenprojekt Energiewende : Elektroenergiepolitik im Spannungsfeld zwischen Vision und Mission / Herbert Niederhausen (Hrsg.)}, booktitle = {Generationenprojekt Energiewende : Elektroenergiepolitik im Spannungsfeld zwischen Vision und Mission / Herbert Niederhausen (Hrsg.)}, publisher = {Books on Demand}, address = {Norderstedt}, isbn = {9783755774389}, pages = {125 -- 136}, year = {2022}, language = {de} } @incollection{AltherrDoerigEdereretal.2017, author = {Altherr, Lena and D{\"o}rig, Bastian and Ederer, Thorsten and Pelz, Peter Franz and Pfetsch, Marc and Wolf, Jan}, title = {A mixed-integer nonlinear program for the design of gearboxes}, series = {Operations Research Proceedings 2016}, booktitle = {Operations Research Proceedings 2016}, publisher = {Springer}, address = {Cham}, isbn = {978-3-319-55701-4}, doi = {10.1007/978-3-319-55702-1_31}, pages = {227 -- 233}, year = {2017}, abstract = {Gearboxes are mechanical transmission systems that provide speed and torque conversions from a rotating power source.

In the face of more than 75 RPA products currently on the market, guidance considering those specifics is required. Therefore, this chapter proposes a criteria-based selection method specifically for RPA. The method includes a quantitative evaluation of costs and benefits as well as a qualitative utility analysis based on functional criteria. By using the visualization of financial implications (VOFI) method, an application-oriented structure is provided that opposes the total cost of ownership to the time savings times salary (TSTS). For the utility analysis a detailed list of functional criteria for RPA is offered. The whole method is based on a multi-vocal review of scientific and non-scholarly literature including publications by business practitioners, consultants, and vendors. The application of the method is illustrated by a concrete RPA example. The illustrated structures, templates, and criteria can be directly utilized by practitioners in their real-life RPA implementations.

Conductive charging stations, which are today's state of the art, are of limited suitability for urbanised areas, since they cause a significant diversification in townscape. Furthermore, they might be destroyed by vandalism. Besides for those urbanistic reasons, inductive charging stations are a much more comfortable alternative, especially in urbanised areas. The usage of conductive charging stations requires more or less bulky charging cables. The handling of those standardised charging cables, especially during poor weather conditions, might cause inconvenience, such as dirty clothing etc. Wireless charging does not require visible and vandalism vulnerable charge sticks. No wired connection between charging station and vehicle is needed, which enable the placement below the surface of parking spaces or other points of interest. Inductive charging seems to be the optimal alternative for E-Mobility, as a high power transfer can be realised with a manageable technical and financial effort. For a well-accepted and working public charging infrastructure in urbanised areas it is essential that the infrastructure fits the vehicles' needs. Hence, a well-adjusted standardisation of the charging infrastructure is essential. This is carried out by several IEC (International Electrotechnical Commission) and national standardisation committees.

First, a multi-speed system is able to improve the overall energy efficiency. Secondly, it is able to reduce the maximum momentum and therefore to reduce the maximum current provided by the traction battery, which results in a longer battery lifetime. In this paper, we present a systematic way to generate multi-gear gearbox designs that—combined with a certain electric motor—lead to the most efficient fulfillment of predefined load scenarios and are at the same time robust to uncertainties in the load. Therefore, we model the electric motor and the gearbox within a Mixed-Integer Nonlinear Program, and optimize the efficiency of the mechanical parts of the powertrain. By combining this mathematical optimization program with an unsupervised machine learning algorithm, we are able to derive global-optimal gearbox designs for practically relevant momentum and speed requirements.}, language = {en} } @incollection{LuczakWolfMuehlfelder2001, author = {Luczak, Holger and Wolf, Martin and M{\"u}hlfelder, M.}, title = {Arbeitswissenschaft}, series = {CSCW-Kompendium : Lehr- und Handbuch zum computerunterst{\"u}tzten kooperativen Arbeiten ; mit 9 Tabellen}, booktitle = {CSCW-Kompendium : Lehr- und Handbuch zum computerunterst{\"u}tzten kooperativen Arbeiten ; mit 9 Tabellen}, editor = {Schwabe, Gerhard}, publisher = {Springer}, address = {Berlin}, isbn = {978-3-540-67552-5}, doi = {10.1007/978-3-642-56848-0_2}, pages = {7 -- 14}, year = {2001}, abstract = {Unter Arbeit wird das T{\"a}tigsein des Menschen verstanden, bei dem dieser mit anderen Menschen und (technischen) Hilfsmitteln in Interaktion tritt, um unter wirtschaftlichen Zielsetzungen G{\"u}ter und Dienstleistungen zu erstellen (Luczak, 1998a).

The management of a shared car fleet, the energy management of electric mobility and the management of various carsharing users with individual likes and dislikes are just some of the major challenges of e-carsharing.
