Azobenzenes and dithiocarbamates in molecular film devices
No full textThe “top-down” approach to improve the performance of small electronic devices is becoming more and more challenging due to economic and engineering restrictions. Thus, researchers seek for alternatives towards efficient, smaller and faster devices. The “bottom-up” method, in which molecules or molecular films implement electronic functionalities, is an outstanding challenge for scientists. The functionalization of metals with molecular films changes the metals’ characteristics and thus the tuning of device properties is possible. The fundamental research of exploring functionalized surfaces is the driving force of this PhD-work. In particular, the focus will be set on the electronic communication between two interfaces which have to be considered when gearing towards applications such as organic light-emitting diodes and organic field?effect transistors. The investigations on appropriate metal-molecule and molecule-semiconductor interfaces are crucial to improve the charge transport of a molecular thin film device. The exploration of the metal’s work function is of particular interest and is the main aspect addressed in this work. However, the modulation of the molecular backbone to tune the crystallinity of the self?assembled monolayer and thus the electronic properties of the metal is also investigated within this project.
The design, synthesis and characterization of molecular structures bearing azobenzenes and dithiocarbamates, which are appealing functional units, is presented in this work. Subsequently, the self-assembled monolayers of these structures are prepared and the interdependence of the self-assembled monolayers and the substrate electrodes is investigated. These studies are performed in a close collaboration with the research groups of Prof. P. Samorì, Prof. Dr. B. Doudin, Prof. C. Wöll and Prof. M. A. Rampi and with Dr. F. von Wrochem and Dr. W. Ford from the Material Science Laboratory of SONY Deutschland GmbH. Within this research activity the main aim is to obtain a deeper understanding of the correlation between the structural architecture of molecular films and the overall device’s electronic performance

Vision-based 3D Human Motion Analysis in a Hierarchical Way
No full textIn the last decade, computer vision has drawn more and more attention because of its potential applications in our daily lives, such as health care, education, safety, and training. However the high complexity of many of the vision-based approaches hinders their practical applications, especially in applications where immediate feedback is required. This thesis focuses on developing fast and robust algorithms to track multiple people in a scene, which can be used in applications like interactive education, crisis analysis, serious games, or virtual reality. We proposed a complete system for people tracking and interaction recognition. This system consists of three modules: detection and tracking persons from a single camera view, position estimation of body parts of each person from multiple camera views, and human pose and interaction recognition. In the first module, we detect and track people in a single camera view. A simple and efficient approach is proposed to track a single person’s motion in real time. Based on this approach, we designed a pose-driven spatial game, which demonstrated a practical vision-based application. Further, we extended this single person tracking approach into multiple people tracking, by using color information to distinguish persons. Due the simplicity of the features and the simplified model, the tracker is able to track two persons simultaneously in close real-time. In the second module, we investigate multiple view approaches for multiple people tracking and pose estimation. The advantages of multiple view approaches over single view approaches are more camera views and better depth estimation. Multiple view approaches can lead to more accurate tracking compared with single view approaches, especially for multiple persons tracking. We proposed a novel approach that combines multiple views in such a way that we rely more on the features derived from clear views and less on those from occluded views. In this way, the proposed approach leads to accurate tracking results at much lower computational costs. In the third module, we use the tracking results (positions of body parts) to represent and recognize human interactions. We investigate what are the most informative features to distinguish the interactions while keeping good recognition performance. The necessity of informative feature lies in practical applications. By using the informative features, even a linear classifier is shown to be sufficient for interaction recognition. This is quite attractive from a computational point of view. Our proposed approaches do not only contribute to academic research in vision-based human motion analysis, but also provide practical solutions to innovative human computer interactions.Intelligent SystemsElectrical Engineering, Mathematics and Computer Scienc
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Forecasting errors in the averseness of apologizing
No full textApologizing is often seen as the appropriate response after a transgression for perpetrators. Yet, despite the positive effects that apologies elicit after situations of conflict, they are not always delivered easily. We argue that this is due –at least in part- to perpetrators overestimating the averseness of apologizing, thus committing a forecasting error. Across two laboratory experiments and one autobiographical recall study, we demonstrate that perpetrators overestimate the averseness they will experience when apologizing compared to the averseness they experience when they actually apologize. Moreover, we show that this effect is driven by a misconstrual of the effects of an apology. Perpetrators overestimate the potentially negative effects of apologizing while simultaneously underestimating the potentially positive effects of apologizing. This forecasting error may have a negative effect on the initiation of the reconciliation process, due to perpetrators believing that apologizing is more averse than it actually is
