The working principle meanwhile gives rise to the crucial problem and challenge to protect the metasurface from dust or clean the unavoidable contaminants during daily usage. Here, taking advantage of the intelligent bioinspired surfaces which exhibit self-cleaning properties, a versatile dielectric metasurface benefiting from the obtained superhydrophilic or quasi-superhydrophobic states is shown. The design is realized by embedding the metasurface inside a large area of wettability supporting structures, which is highly efficient in fabrication, and achieves both optical and wettability functionality at the same time. The superhydrophilic state enables an enhanced optical response with water, while the quasi-superhydrophobic state imparts the fragile antennas an ability to self-clean dust contamination. Furthermore, the metasurface can be easily switched and repeated between these two wettability or functional states by appropriate treatments in a repeatable way, without degrading the optical performance. The proposed design strategy will bring new opportunities to smart metasurfaces with improved optical performance, versatility, and physical stability."}],"file":[{"relation":"main_file","success":1,"content_type":"application/pdf","file_id":"26748","access_level":"closed","file_name":"AdvOptMat_Lu_2021.pdf","file_size":2801333,"creator":"zentgraf","date_created":"2021-10-25T06:42:52Z","date_updated":"2021-10-25T06:42:52Z"}],"ddc":["530"],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2195-1071","2195-1071"]},"has_accepted_license":"1","publication_status":"published","intvolume":" 10","citation":{"ieee":"J.

For certain modes of high angular order, the incident wave is able to transfer its directionality to the field in the fiber, exciting effectively only one of a pair of degenerate OAM modes"}],"file":[{"relation":"main_file","content_type":"application/pdf","file_id":"30444","file_name":"2022-03 Hammer - SPIE Photonics West 2022 - Resonant evanescent excitation of OAM modes in a high-contrast circular (official version).pdf","access_level":"open_access","file_size":2015899,"creator":"fossie","date_created":"2022-03-22T18:03:50Z","date_updated":"2022-03-22T18:03:50Z"}],"publication":"Complex Light and Optical Forces XVI","ddc":["530"],"keyword":["tet_topic_waveguide"],"language":[{"iso":"eng"}],"year":"2022","title":"Resonant evanescent excitation of OAM modes in a high-contrast circular step-index fiber","publisher":"SPIE","date_created":"2022-03-21T10:12:58Z"},{"publication_status":"published","citation":{"chicago":"Schulz, Michael, Uwe Neuhaus, Jens Kaufmann, Stephan Kühnel, Emal M.

Therefore, our vision is the provision of model-driven continuous experimentation, which provides the developer with a framework for structuring the experimentation process. For that, we introduce the overall concept, apply it to the experimentation on component-based software architectures and point out future research questions. In particular, we show the applicability by combining feature models for modeling the software variants, users, and experiments (i.e., model-driven) with MAPE-K for the adaptation (i.e., continuous experimentation) and implementing the concept based on the component-based Angular framework.","lang":"eng"}],"file":[{"date_updated":"2022-07-04T12:34:52Z","creator":"sego","date_created":"2022-07-04T12:33:18Z","file_size":183185,"access_level":"open_access","file_id":"32322","file_name":"ICSA_CR.pdf","content_type":"application/pdf","relation":"main_file"}],"publication":"Proceedings of the 18th International Conference on Software Architecture Companion ","title":"Model-driven Continuous Experimentation on Component-based Software Architectures ","publisher":"IEEE","date_created":"2022-02-15T07:32:10Z","year":"2022","file_date_updated":"2022-07-04T12:34:52Z","project":[{"_id":"1","name":"SFB 901: SFB 901"},{"_id":"4","name":"SFB 901 - C: SFB 901 - Project Area C"},{"name":"SFB 901 - C5: SFB 901 - Subproject C5","_id":"17"}],"_id":"29842","user_id":"47208","department":[{"_id":"66"},{"_id":"534"}],"status":"public","type":"conference","doi":"10.1109/ICSA-C54293.2022.00011","conference":{"end_date":"2022-03-15","location":"Hawaii","name":"18th International Conference on Software Architecture ","start_date":"2022-03-12"},"date_updated":"2022-07-04T12:34:53Z","oa":"1","author":[{"first_name":"Sebastian","last_name":"Gottschalk","id":"47208","full_name":"Gottschalk, Sebastian"},{"orcid":"0000-0002-5967-833X","last_name":"Yigitbas","full_name":"Yigitbas, Enes","id":"8447","first_name":"Enes"},{"id":"107","full_name":"Engels, Gregor","last_name":"Engels","first_name":"Gregor"}],"citation":{"chicago":"Gottschalk, Sebastian, Enes Yigitbas, and Gregor Engels. “Model-Driven Continuous Experimentation on Component-Based Software Architectures .” In Proceedings of the 18th International Conference on Software Architecture Companion .

Abgesehen von den konventionellen Methoden um einen Trojaner in eine Schaltung für ein Field-programmable Gate Array (FPGA) einzuschleusen, können auch die Entwurfswerkzeuge heimlich kompromittiert werden um einen Angreifer dabei zu unterstützen einen erfolgreichen Angriff durchzuführen, der zum Beispiel Fehlfunktionen oder ungewollte Informationsabflüsse bewirken kann. Diese Dissertation beschäftigt sich hauptsächlich mit den beiden Blickwinkeln auf Hardwaretrojaner in rekonfigurierbaren Systemen, einerseits der Perspektive des Verteidigers mit einer Methode zur Erkennung von Trojanern auf der Bitstromebene, und andererseits derjenigen des Angreifers mit einer neuartigen Angriffsmethode für FPGA Trojaner. Für die Verteidigung gegen den Trojaner ``Heimtückische LUT'' stellen wir die allererste erfolgreiche Gegenmaßnahme vor, die durch Verifikation mittels Proof-carrying Hardware (PCH) auf der Bitstromebene direkt vor der Konfiguration der Hardware angewendet werden kann, und präsentieren ein vollständiges Schema für den Entwurf und die Verifikation von Schaltungen für iCE40 FPGAs. Für die Gegenseite führen wir einen neuen Angriff ein, welcher bösartiges Routing im eingefügten Trojaner ausnutzt um selbst im fertigen Bitstrom in einem inaktiven Zustand zu verbleiben: Hierdurch kann dieser neuartige Angriff zur Zeit weder von herkömmlichen Test- und Verifikationsmethoden, noch von unserer vorher vorgestellten Verifikation auf der Bitstromebene entdeckt werden.","lang":"eng"},{"lang":"eng","text":"The battle of developing hardware Trojans and corresponding countermeasures has taken adversaries towards ingenious ways of compromising hardware designs by circumventing even advanced testing and verification methods. Besides conventional methods of inserting Trojans into a design by a malicious entity, the design flow for field-programmable gate arrays (FPGAs) can also be surreptitiously compromised to assist the attacker to perform a successful malfunctioning or information leakage attack. This thesis mainly focuses on the two aspects of hardware Trojans in reconfigurable systems, the defenders perspective which corresponds to the bitstream-level Trojan detection technique, and the attackers perspective which corresponds to a novel FPGA Trojan attack. From the defender's perspective, we introduce a first-ever successful pre-configuration countermeasure against the ``Malicious LUT''-hardware Trojan, by employing bitstream-level Proof-Carrying Hardware (PCH) and present the complete design-and-verification flow for iCE40 FPGAs. Likewise, from an attackers perspective, we present a novel attack that leverages malicious routing of the inserted Trojan circuit to acquire a dormant state even in the generated and transmitted bitstream. Since the Trojan is injected in a post-synthesis step and remains unconnected in the bitstream, the presented attack can currently neither be prevented by conventional testing and verification methods nor by bitstream-level verification techniques."}],"language":[{"iso":"eng"}],"ddc":["004"],"keyword":["FPGA Security","Hardware Trojans","Bitstream-level Trojans","Bitstream Verification"],"year":"2022","title":"Hardware Trojans in Reconfigurable Computing","date_created":"2022-02-07T14:02:36Z","publisher":" Paderborn University, Paderborn, Germany"},{"year":"2022","date_created":"2022-10-11T07:27:51Z","title":"End-to-End Dereverberation, Beamforming, and Speech Recognition in A Cocktail Party","publication":"IEEE/ACM Transactions on Audio, Speech, and Language Processing","license":"https://creativecommons.org/publicdomain/zero/1.0/","file":[{"date_updated":"2022-10-11T07:23:13Z","creator":"huesera","date_created":"2022-10-11T07:23:13Z","content_type":"application/pdf","file_size":6167931,"file_name":"End-to-End_Dereverberation_Beamforming_and_Speech_Recognition_in_A_Cocktail_Party.pdf","file_id":"33674","access_level":"open_access","relation":"main_file"}],"abstract":[{"lang":"eng","text":"Far-field multi-speaker automatic speech recognition (ASR) has drawn increasing attention in recent years. Most existing methods feature a signal processing frontend and an ASR backend. In realistic scenarios, these modules are usually trained separately or progressively, which suffers from either inter-module mismatch or a complicated training process. In this paper, we propose an end-to-end multi-channel model that jointly optimizes the speech enhancement (including speech dereverberation, denoising, and separation) frontend and the ASR backend as a single system. To the best of our knowledge, this is the first work that proposes to optimize dereverberation, beamforming, and multi-speaker ASR in a fully end-to-end manner. The frontend module consists of a weighted prediction error (WPE) based submodule for dereverberation and a neural beamformer for denoising and speech separation. For the backend, we adopt a widely used end-to-end (E2E) ASR architecture. It is worth noting that the entire model is differentiable and can be optimized in a fully end-to-end manner using only the ASR criterion, without the need of parallel signal-level labels. We evaluate the proposed model on several multi-speaker benchmark datasets, and experimental results show that the fully E2E ASR model can achieve competitive performance on both noisy and reverberant conditions, with over 30% relative word error rate (WER) reduction over the single-channel baseline systems."}],"language":[{"iso":"eng"}],"ddc":["000"],"related_material":{"link":[{"relation":"confirmation","url":"https://ieeexplore.ieee.org/abstract/document/9904314"}]},"has_accepted_license":"1","publication_identifier":{"issn":["Print ISSN: 2329-9290 Electronic ISSN: 2329-9304"]},"publication_status":"published","citation":{"short":"W.

The increasing demands on the efficiency and reliabilityof the modules have led to technological developments and copper wires with significantlybetter electrical and thermal properties are used more often nowadays. This results in new challengesin process development due to higher process forces and ultrasonic power; for this purpose,a simulation model is developed to improve process development.Ultrasonic wire bonding tests with 400 m aluminium and copper wires were carried out to investigatethe influence of the process parameters on the bond quality; these results and additionalmeasurements of wire deformation and vibrations were used to define the requirements for themodel and validate the results of the simulation.A process model based on a co-simulation was developed between MATLAB and ANSYS; thephysical phenomena such as ultrasonic softening of the wire material, bond formation and dynamicbehaviour of the components were considered.Based on a tensile-compression testing machine, a test rig was developed to identify the modelparameters. In additional compression tests with the wires with and without ultrasonic excitation,the reduction of the forming forces under ultrasonic influence was characterised.With the developed process model, the parameter studies from the ultrasonic wire bond testswere simulated and directly compared with the experimental results; a relative good agreementbetween simulation and measurement could be achieved for both aluminium and copper."}]}]
