Existing approaches often require strict assumptions about or perfect knowledge of the underlying radio system, its resource allocation scheme, or user movements, none of which is readily available in practice.\r\n\r\nInstead, we propose three novel self-learning and self-adapting approaches using model-free deep reinforcement learning (DRL): DeepCoMP, DD-CoMP, and D3-CoMP. DeepCoMP leverages central observations and control of all users to select cells almost optimally. DD-CoMP and D3-CoMP use multi-agent DRL, which allows distributed, robust, and highly scalable coordination. All three approaches learn from experience and self-adapt to varying scenarios, reaching 2x higher Quality of Experience than other approaches. They have very few built-in assumptions and do not need prior system knowledge, making them more robust to change and better applicable in practice than existing approaches."}],"title":"DeepCoMP: Coordinated Multipoint Using Multi-Agent Deep Reinforcement Learning","ddc":["004"],"user_id":"477","year":"2021","citation":{"short":"S.B.

For an efficient use of solar and wind energy in an energy system, correct design and sizing of a power system is of high importance and improving or optimizing the process of data obtaining for this purpose leads to higher performance and lower cost per unit of energy. It is essential to have the most precise possible estimation of solar and wind energy potential and other local weather parameters in order to fully feed the demand and avoid extra costs. There are various methods for obtaining local data, such as local measurements, official organizational data, satellite obtained, and reanalysis data. In this paper, the Modern-Era Retrospective analysis for Research and Applications dataset version 2 (MERRA-2) dataset provided by NASA is introduced and its performance is evaluated by comparison to various locally measured datasets offered by meteorological institutions such as Meteonorm and Deutscher Wetterdienst (DWD, or Germany’s National Meteorological Service) around the world. After comparison, correlation coefficients from 0.95 to 0.99 are observed for monthly global horizontal irradiance values. In the case of air temperature, correlation coefficients of 0.99 and for wind speed from 0.81 to 0.99 are observed. High correlation with ground measurements and relatively low errors are confirmed, especially for irradiance and temperature values, that makes MERRA-2 a valuable dataset, considering its world coverage and availability.","lang":"eng"}],"article_type":"original","user_id":"28836","ddc":["620"],"file":[{"access_level":"closed","file_name":"energies-14-00882 Khatibi Krauter MERRA 2.pdf","date_created":"2022-01-06T13:33:09Z","content_type":"application/pdf","date_updated":"2022-01-06T13:33:09Z","success":1,"relation":"main_file","file_size":3837152,"file_id":"29177","creator":"krauter"}],"publication":"Energies","file_date_updated":"2022-01-06T13:33:09Z","keyword":["Solar irradiance","MERRA 2","Meteonorm","DWD"],"quality_controlled":"1","author":[{"first_name":"Arash","full_name":"Khatibi, Arash","last_name":"Khatibi","id":"43538"},{"first_name":"Stefan","full_name":"Krauter, Stefan","orcid":"0000-0002-3594-260X","last_name":"Krauter","id":"28836"}],"publisher":"MDPI","date_created":"2021-02-23T10:18:05Z","has_accepted_license":"1","status":"public","volume":14,"_id":"21265","intvolume":" 14","issue":"4","article_number":"882","main_file_link":[{"open_access":"1","url":"https://www.mdpi.com/1996-1073/14/4/882/htm"}],"type":"journal_article","citation":{"chicago":"Khatibi, Arash, and Stefan Krauter. “Validation and Performance of Satellite Meteorological Dataset MERRA-2 for Solar and Wind Applications.” Energies 14, no. 4 (2021). https://doi.org/10.3390/en14040882.","ama":"Khatibi A, Krauter S.

In this work, we present a dual amplitude holographic scheme based on the photon sieve principle, which is then combined with a phase hologram by utilizing the Pancharatnam–Berry phase. We demonstrate that two types of apertures, rectangular and square shapes in a gold film filled with silicon nanoantennas are sufficient to create two amplitude holograms at two different wavelengths in the visible, multiplexed with an additional phase-only hologram. The nanoantennas are tailored to adjust the spectral transmittance of the apertures, enabling the wavelength sensitivity. The phase-only hologram is implemented by utilizing the anisotropic rectangular structure. Interestingly, such three holograms have quantitative mathematical correlations with each other. Thus, the flexibility of polarization and wavelength channels can be utilized with custom-tailored features to achieve such amplitude and phase holography simultaneously without sacrificing any space-bandwidth product. The present scheme has the potential to store different pieces of information which can be displayed separately by switching the wavelength or the polarization state of the reading light beam.","lang":"eng"}],"date_created":"2021-10-28T07:15:52Z","status":"public","volume":10,"publication":"Nanophotonics","author":[{"full_name":"Frese, Daniel","first_name":"Daniel","last_name":"Frese"},{"first_name":"Basudeb","full_name":"Sain, Basudeb","last_name":"Sain"},{"last_name":"Zhou","first_name":"Hongqiang","full_name":"Zhou, Hongqiang"},{"first_name":"Yongtian","full_name":"Wang, Yongtian","last_name":"Wang"},{"last_name":"Huang","first_name":"Lingling","full_name":"Huang, Lingling"},{"id":"30525","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas","first_name":"Thomas"}],"quality_controlled":"1","publisher":"De Gruyter","issue":"18","_id":"26987","intvolume":" 10","page":"4543-4550","year":"2021","type":"journal_article","citation":{"ieee":"D.

Kredite für die Gründung oder den Ausbau von Unternehmen waren auf Grund des Kapitalmangels entweder unmöglich oder extrem teuer – ein für die wirtschaftliche Entwicklung ernst zu nehmendes Hemmnis. Das Land brauchte zur wirtschaftlichen Entwicklung also Investitionen aus dem Ausland. Jedoch hielten sich die europäischen Banken und Anleger mit solchen Investitionen vor den 1870er Jahren zurück. Warum diese Scheu der Kapitalanleger vor Griechenland, obwohl sie anderswo keineswegs vor risikoreichen Investitionen zurückschreckten, wenn nur entsprechend hohe Erträge lockten? Dieser Frage möchte der Beitrag anhand eines Beispiels nachgehen: der bayerisch-französischen Bankiersfamilie von Eichthal, die in den 1830er Jahren enge Geschäftsbeziehungen nach Griechenland aufbaute und zeitweilig sehr interessiert an Investitionen war – bevor das Bankhaus sich von diesen Plänen schließlich unverrichteter Dinge wieder abwandte. Das kulturelle Interesse an Griechenland überdauerte dagegen bis in die 1880er Jahre. Die Eichthals eignen sich hervorragend, um paradigmatisch zu untersuchen, auf welcher Grundlage und wie europäische Bankiers ihre Investitionsentscheidungen für oder gegen Griechenland trafen.","lang":"ger"}],"user_id":"89037","title":"Finanzielle Netze.

FPGAs are well-suited for many of these applications, but there is a reluctance in the robotics community to use hardware acceleration due to increased design complexity and a lack of consistent programming models across the software/hardware boundary. In this paper we present ReconROS, a framework that integrates the widely-used robot operating system (ROS) with ReconOS, which features multithreaded programming of hardware and software threads for reconfigurable computers. This unique combination gives ROS2 developers the flexibility to transparently accelerate parts of their robotics applications in hardware. We elaborate on the architecture and the design flow for ReconROS and report on a set of experiments that underline the feasibility and flexibility of our approach."}],"date_created":"2021-07-16T05:38:56Z","status":"public","publication":"arXiv:2107.07208","department":[{"_id":"78"}],"author":[{"last_name":"Lienen","id":"60323","first_name":"Christian","full_name":"Lienen, Christian"},{"last_name":"Platzner","id":"398","first_name":"Marco","full_name":"Platzner, Marco"}],"oa":"1","_id":"22764","date_updated":"2022-01-28T08:30:24Z","page":"19","type":"preprint","year":"2021","citation":{"short":"C.
