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

Alternate bearing of 'Golden Reinders' and 'Summered' apples
No full textThe aim of the present study was to study the effect of biennial bearing (irregular yields) on the generative production of apple cultivars 'Golden Reinders' and 'Summerred' on M.9 rootstock. The observations were made at Nagykutas in West-Hungary for four years. The authors have studied the flowering time, flower density, fruit density, fruit drop, seed content, yielding and fruit quality in the on-year and off-year. Based on the results, it can be stated that the alternation does not cause a significant change in the flowering time of cvs. 'Golden Reinders' and `Summerred': the difference between the flowering time of trees in the on-year and off-year period was 0-1 day. However, there were significant differences in the flower density. 'Golden Reinders' proved to have a weaker tendency to alternation similarly to the statements of the literature. Alternation (off-year) was observed only in three years from the studied four years. While in the case of `Summerred', strong alternation was observed in all four years. In fruit density, there were differences among the cultivars and among the different cycles of biennial bearing. Fruit density (and its opposite, fruit drop) changed inconsistently in the period between flowering and harvest. In the case of 'Golden Reinders' and 'Summerred' 2 and 4 fruit drop periods were detected, respectively. In the off-year, the different periods were less distinct, in most cases they were overlapping each other. The dynamics of fruit drop was related to seed content per fruit. The lower the seed number was, the higher the degree of fruit drop was. In both the high- and off-year cycles, the number of seeds in fruits on the tree and on the ground increased with time. In the yield parameters (fruit number, fruit load, yield efficiency), the differences were greater among the yields of trees in the high- and off-year cycles for 'Summerred'. The fruit quality parameters were greatly influenced by the fruit load of the trees in the different alternation cycles. In general, it can be stated that fruit mass, diameter and height were lower on trees in the on-year. A similar trend could be observed in flesh firmness, cover colour and dry matter content, but the differences were smaller. 'Summerred' was more sensitive to the differences in fruit load
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

No full textLearning from weakly representative data and applications in spectral image analysis
No full textSpectral imaging has been extensively applied in many fields, including agriculture, environmental monitoring, biomedical diagnostics, etc. Thanks to the advances in sensor technology, spectral imaging systems nowadays provide finer and finer spectral resolution needed to characterize the spectral properties of materials. The high spectral resolution, however, raises an issue as the difference in spectral information between two adjacent wavelength bands is typically very small. As a result, much of the data in a scene seems to be redundant. However, critical information is embedded that often can be used to identify materials. This thesis aims at facilitating the analysis in spectral imaging by making use of pattern recognition techniques, on the one hand, to improve visualization, and on the other hand, to directly solve classification problems.Intelligent SystemsElectrical Engineering, Mathematics and Computer Scienc
