This paper presents findings from an in-depth eye-tracking study with 103 participants, evaluating the effectiveness of phishing awareness tools and trainings. The study examines how a phishing awareness system influences user behavior, efficiency, and the ability to identify phishing attempts. By analyzing eye movements, the study reveals real-time interactions and oversights, providing insights into the decision-making process. Results indicate that while the system improves the efficiency of users already proficient in phishing detection, it does not universally enhance recognition rates. Notably, participants using the tool spent significantly less time looking at attachment-related phishing markers, indicating partial efficiency improvements. Since phishing attempts containing suspicious attachments were successful in 19\% of cases, as compared to an overall phishing success rate of 15\%, the phishing awareness tool is particularly useful here. A usability evaluation revealed that users reporting a higher perceived usability score profited more from the help of the tool. Additionally, no improvement in phishing detection rates was observed in users who had completed prior IT-security training, highlighting the necessity for a paradigm shift in phishing training to adequately prepare users for phishing attempts.}, language = {en} } @inproceedings{SetzpfandtSolntsevTitcheneretal., author = {Setzpfandt, Frank and Solntsev, Alexander S. and Titchener, James and Wu, Che Wen and Xiong, Chunle and Pertsch, Thomas and Schiek, Roland and Neshev, Dragomir N. and Sukhorukov, Andrey A.}, title = {Optically Tunable Entangled Photon State Generation in a Nonlinear Directional Coupler}, series = {Nonlinear Optics [Kauai, Hawaii 26-31 July 2015]}, booktitle = {Nonlinear Optics [Kauai, Hawaii 26-31 July 2015]}, number = {paper NW2A.4}, publisher = {OSA}, address = {Washington, D.C.}, isbn = {978-1-55752-001-2}, doi = {10.1364/nlo.2015.nw2a.4}, abstract = {We propose and experimentally demonstrate an all-optically tunable biphoton quantum light source using a nonlinear directional coupler.

It is becoming increasingly rare for elementary school children to come to grips with technology in the sense of recognizing functional interrelationships and understanding modes of action in the context of technical-practical confrontation. The picture at secondary schools is also rather sobering. Here, a strong focus on facts and knowledge and too little emphasis on modeling, application and problem solving lead to insufficient results in the cognitive area. In addition, a massive shortage of engineers and specialists with a technical and scientific orientation has been predicted for years and is being increasingly observed. The motivation of students in traditional lectures is decreasing and in general there is a decline of university students in technical subjects. These problems are not only known throughout Germany, but also internationally. Especially in developing countries, additional problems make technical education more difficult, regardless of the type of school. Therefore, this master thesis is evaluated in South Africa in order to consider as many influencing factors as possible. "Learning is experience. Everything else is simply information." - Methods and concepts developed in the thesis build upon this quote of Albert Einstein. Teaching methods are elaborated and applied for three different age groups and school types, depending on known influencing factors. The aim of this thesis is not to produce further findings in the sense of basic research, but to show ways in which the current situation can be steered in a different direction. It has been shown that technology lessons in elementary/secondary schools inspire interest in technical professions in the field of electrical engineering. Furthermore, the combination of frontal teaching, for a necessary theoretical background, together with student-active, action-oriented teaching shows advantages in terms of learning efficiency and an increase in performance levels for all three age groups. However, it could also be observed that factors such as social background, family influence and gender have partial effects on the promotion and education in the field of electrical engineering.}, language = {en} } @masterthesis{Marterer, type = {Bachelor Thesis}, author = {Marterer, Verena}, title = {Simulation der elektromagnetischen Eigenschaften von gestricktem Stoff}, address = {Regensburg}, doi = {10.35096/othr/pub-5760}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:898-opus4-57605}, school = {Ostbayerische Technische Hochschule Regensburg}, abstract = {Periodische Strukturen besitzen eine Reihe interessanter Eigenschaften, die sie unter anderem f{\"u}r den Einsatz im Bereich der Hochfrequenz- und Mikrowellentechnik attraktiv erscheinen lassen. In der vorliegenden Arbeit steht insbesondere deren Anwendung beim Entwurf gestrickter Stoffe, die auf metallischen F{\"a}den basieren, im Vordergrund. Es wird in diesem Zusammenhang zun{\"a}chst die vollst{\"a}ndige Modellierung der Struktur unter Verwendung von 3D-Elementen in repr{\"a}sentativen Elementarzellen durchgef{\"u}hrt. Innerhalb der Designumgebung von CST Studio Suite kann das analytische Elementarmodell von Leaf und Glaskin f{\"u}r die Einfaden-Maschenware implementiert werden. Abh{\"a}ngig von den variablen Faktoren beim Stricken bewegen sich die Kantenl{\"a}ngen der hier betrachteten Einheitszelle in der Gr{\"o}ßenordnung von 1 cm bis 2 cm. Bei der Analyse der elektromagnetischen Eigenschaften unter Verwendung eines Frequenzbereichsl{\"o}sers k{\"o}nnen somit die Streuparameter f{\"u}r Reflexion und Transmission in einem Frequenzbereich von 13 GHz bis 30 GHz ermittelt werden. Aus den 1D-Simulationsergebnissen werden Frequenzen sichtbar, bei denen Resonanzph{\"a}nomene auftreten. Die polarisationsabh{\"a}ngigen Strukturen weisen Abschirmwirkungen von 30 dB und mehr auf. Da das Resonanzverhalten mit den Oberfl{\"a}chenstr{\"o}men in Verbindung steht, wird die Oberfl{\"a}chenstromverteilung zeitgleich mit dem elektrischen Feld untersucht. Weiterhin wird den Wechselwirkungen zwischen den ver{\"a}nderlichen Strickparametern und den elektromagnetischen Spezifikationen wie Resonanzfrequenz, Bandbreite oder G{\"u}te Aufmerksamkeit geschenkt.
