description: Die vorliegende Arbeit untersuchte die Frage, welche Bedeutung sexuelle Fantasien in der Sexualberatung nach Sexocorporel haben. Dabei wurde den Fragen nachgegangen, wie sexuelle Fantasien innerhalb des Modells zu verstehen sind und welche beraterischen Interventionen sich rund um sexuelle Fantasien in der Sexualberatung nach Sexocorporel anbieten. Zur theoretischen Einbettung des Konzepts der sexuellen Fantasie, wurden Literatur und Studien aus den Bereichen der kognitiven Psychologie, der Sexualwissenschaft, der systemischen Therapie, bezüglich der Sexoanalyse und des Modells Sexocorporel hinzugezogen. Um die Fragestellungen zu beantworten wurden Expert*inneninterviews mit drei Sexualberater*innen durchgeführt, welche nach dem Sexocorporel-Ansatz arbeiten. Basierend auf einer qualitativen Auswertungsmethode nach Bogner, Littig, und Menz (2014), welche sich an der Grounded-Theory-Methodologie orientiert, wurden die Interviews kodiert und ausgewertet. Aus den Daten ergaben sich folgende zentrale Themen: Offenheit der Definition sexueller Fantasien; Sexuelle Fantasie als Teil des Körpers; Sexuelle Fantasien und das Bedürfnis nach genitaler Erregung; Sexuelle Fantasien im Kontext der Paarbeziehung; Sexuelle Fantasie als Möglichkeitsform – können statt sein; Vielfalt der Interventionen. Die vorliegende Arbeit zeigt auf, dass sich rund um sexuelle Fantasien verschiedene Interventionen anbieten, die beraterisch vielseitig eingesetzt werden können. Es wird diskutiert, dass auch die Scham, häufig im Zusammenhang mit sexuellen Fantasien auftretend, ihre Sinnhaftigkeit hat und beraterisch genutzt werden kann.

description: The effect of formalin on the organoleptic parameters, biochemical composition and storage quality of iced and frozen stored giant freshwater prawns (Macrobrachium rosenbergii) was investigated. The organoleptic characters such as appearance, textural condition, colour, odour of both formalin added and non-added prawns were evaluated. The quality of non-added prawns was judged good up to first 3 days of iced storage and remained acceptable in terms of commercial standard for processing in the industry up to 6 days. On the other hand, formalin added samples were organoleptically acceptable up to 8 days. The expressible moisture content of both formalin added and non-added prawns continued to increase gradually during 90 days of frozen storage and it was higher in non-added sample. Study of proximate composition at initial storage showed that there were variations in composition between formalin added and non-added samples. At the end of 10 days of iced storage, there was little change in composition in both the cases. To assess the freshness of the prawn samples, TVB-N value and myofibrillar protein solubility were determined. Under iced storage, there was a clear trend of increasing TVB-N value both in formalin added and nonadded samples with higher value in non-added sample. The initial myofibrillar protein solubility of formalin added prawn was 88% and that of non-added sample was 80%. After 10 days of iced storage, the protein solubility of both the samples decreased to 50% of their initial value. The solubility of myofibrillar protein of formalin added prawn was lower than non-added sample. Overall loss of freshness took place much faster in non-added prawn sample than the formalin added sample both under iced and frozen storage conditions.

description: This paper presents for the first time, to our knowledge, a framework for verifying neural network behavior in power system applications. Up to this moment, neural networks have been applied in power systems as a black-box; this has presented a major barrier for their adoption in practice. Developing a rigorous framework based on mixed integer linear programming, our methods can determine the range of inputs that neural networks classify as safe or unsafe, and are able to systematically identify adversarial examples. Such methods have the potential to build the missing trust of power system operators on neural networks, and unlock a series of new applications in power systems. This paper presents the framework, methods to assess and improve neural network robustness in power systems, and addresses concerns related to scalability and accuracy. We demonstrate our methods on the IEEE 9-bus, 14-bus, and 162-bus systems, treating both N-1 security and small-signal stability.

description: We study the effects of noise on a recently discovered form of intermittency, referred to as in-out intermittency. This type of intermittency, which reduces to on-off in systems with a skew product structure, has been found in the dynamics of maps, ODE and PDE simulations that have symmetries. It shows itself in the form of trajectories that spend a long time near a symmetric state interspersed with short bursts away from symmetry. In contrast to on-off intermittency, there are clearly distinct mechanisms of approach towards and away from the symmetric state, and this needs to be taken into account in order to properly model the long time statistics. We do this by using a diffusion-type equation with delay integral boundary condition. This model is validated by considering the statistics of a two-dimensional map with and without the addition of noise.

title: Three-sided Football and the Alternative Soccerscape: A Study of Sporting Space, Play and Activism
Creators: name: Pollock, Benjin
Publisher: name: University of Kent
Year: 2021

description: Three teams, three goals, and one ball. Devised as an illustrative example of 'triolectics', Danish artist and philosopher Asger Jorn conceived of three-sided football in 1962. However, the game remained a purely abstract philosophical exercise until the early 1990s when a group of anarchists, architects and artists decided to play the game for the first time. Since these early experiments three-sided football has been played across the globe, from 'anarchist' football festivals in Germany, contemporary art installations in France, through to youth outreach programs in Colombia. Far beyond its emergent context, and as a codified and formalised sport, the game continues to resonate for a myriad of social actors in search of alternative ways to play and live in contemporary culture. This thesis provides the first ethnography into three-sided football. In doing so, it privileges much needed player perspectives on how DIY initiatives are attempting to redefine football in response to the hyper commodification of the elite two-sided game. More broadly, this research is an exploration of how societal alternatives (sporting or otherwise) are imagined, produced, fragmented, and transformed as popular practices in the 'fully lived' space. Further, how such spaces are comprised of individual and collective social agencies which respond, and adapt to, pre-existing structures, inherited symbolic practices and received cultural logics. Drawing from forty-four semi-structured interviews with players, coaches, curators and activists from across the social field, this research is situated within the recent contestations over the games trajectory. This demonstrates the complex social dynamics and 'narrative horizons' at play as the three-sided football community has grappled with how best to foster inclusive, less competitive sporting spaces. Also, how the 'strategic appropriation' of the practice within pedagogical settings has offered a sustainable future for the game. In highlighting the heterotopic, dynamic and ontologically uncertain status of three-sided football, this thesis argues that the game offers participants multiple and competing forms of 'practical consciousness' through which to remake the world; be that as a 'desportized' form of football, as an absurd and playful spatial intervention, or as a form of community engagement.

description: Pangasius catfish, Pangasianodoan hypophthalmus farming has been evolved to a shape of commercial enterprise over the last two decades in north-central part of Bangladesh, particularly in Mymensingh area but there is a lack of quantitative and qualitative data on the impacts of it on land use pattern. This study was conducted using multiple methodological tools including participatory rural appraisal (PRA) tools and mainly questionnaire based farm survey to assess the impacts of Pangasius farming on land use from February to September, 2009. The mean farm size (ha), water area (ha) and dyke area (ha) was 1.36±1.25, 1.06±1.31 and 0.30±0.27, respectively. The Pangasius productivity was significantly and positively correlated with water area and dyke area. Around 10.1% area of the study area was converted to Pangasius farm which was previously used as rice-field. Farmers expanded their farm area by taking leased lands which contributed to 56.47% of total farm area and the lease value of Pangasius pond was doubled compared to agriculture land. Around 48% area of dyke were used to produce agriculture crops and the production was 71.01% lower but profit margin was 76.58% higher than normal land. The discharging wastewater of Pangasius pond also increased rice productivity in adjacent agriculture farm by 10% and additionally reduced fertilizer and irrigation cost by 30% and 40%, respectively.

description: The ab-plane thermal conductivity $κ$ of single-crystalline hexagonal MgB_2 has been measured as a function of magnetic field H with orientations both parallel and perpendicular to the c-axis and at temperatures between 0.5 and 300 K. In the mixed state, $κ(H)$ measured at constant temperatures reveals features that are not typical for common type-II superconductors. The observed behavior may be associated with the field-induced reduction of two superconducting energy gaps, significantly different in magnitude. A nonlinear temperature dependence of the electronic thermal conductivity is observed in the field-induced normal state at low temperatures. This behavior is at variance with the Wiedemann-Franz law, and suggests an unexpected instability of the electronic subsystem in the normal state at T ~ 1 K.

description: The probability that an advantageous mutant rises to fixation in a viral quasispecies is investigated in the framework of multi-type branching processes. Whether fixation is possible depends on the overall growth rate of the quasispecies that will form if invasion is successful, rather than on the individual fitness of the invading mutant. The exact fixation probability can only be calculated if the fitnesses of all potential members of the invading quasispecies are known. Quasispecies fixation has two important characteristics: First, a sequence with negative selection coefficient has a positive fixation probability as long as it has the potential to grow into a quasispecies with an overall growth rate that exceeds the one of the established quasispecies. Second, the fixation probabilities of sequences with identical fitnesses can nevertheless vary over many orders of magnitudes. Two approximations for the probability of fixation are introduced. Both approximations require only partial knowledge about the potential members of the invading quasispecies. The performance of these two approximations is compared to the exact fixation probability on a network of RNA sequences with identical secondary structure.

Backward error accurate methods for computing the matrix exponential and its action
Creators: name: Zivcovich, Franco
Publisher: name: Universit� degli studi di Trento
Year: 2020

description: The theory of partial differential equations constitutes today one of the most important topics of scientific understanding. A standard approach for solving a time-dependent partial differential equation consists in discretizing the spatial variables by finite differences or finite elements. This results in a huge system of (stiff) ordinary differential equations that has to be integrated in time. Exponential integrators constitute an interesting class of numerical methods for the time integration of stiff systems of differential equations. Their efficient implementation heavily relies on the fast computation of the action of certain matrix functions; among those, the matrix exponential is the most prominent one. In this manuscript, we go through the steps that led to the development of backward error accurate routines for computing the action of the matrix exponential.
title: Crosspoints: Toward an Integrative Framework for Actor training, Rehearsal and Performance
Creators: name: Atkins, Stephen
Publisher: name: University of Kent
Year: 2021

description: The range of actor training methods used in most conservatoire-style curricula are derived from dramatic text analysis methods pioneered by Constsntin Stanislavski. Predominant shifts in aesthetics such as those ushered forth by postmodernism, new technologies, hybrid arts and cross-cultural collaboration present new problems for the contemporary actor. The broadening of the field of performance suggests that dramatic acting techniques are not universally suited to the expanding horizon of practices. This research extends a tributary of actor training that is generally related to Jerzy Grotowski's work. It uses the term "source" in a way that evokes Grotowski's Theatre of Sources but is not directly connected to it. This research also incorporates pedagogical and sociological theory to outline issues such as symbolic control and "legitimate" versus "avant-garde" cultural production. This work is an exegesis describing the development of the Crosspoints, exaining how it was inspired by the Viewpoints. It documents the process of creating the method through stages of ideation, the invention of exercises and the design of an instructional model (the "pedagogising") of the approach. Through situated practice-based research across multiple sites, exercises were imagined, metaphors and illustrations were created, workshops were taught, and a handbook was written (and illustrated). Accompanying this paper is a handbook intended for actors, directors and teachers. It is the artistic artifact of the process and instructs the reader on ways to incorporate Crosspoints with current acting pedagogy. It also suggests future investigations to extend the system.

description: We compute the gravitational self-force (or ``radiation reaction'' force) acting on a particle falling radially into a Schwarzschild black hole. Our calculation is based on the ``mode-sum'' method, in which one first calculates the individual $\ell$-multipole contributions to the self-force (by numerically integrating the decoupled perturbation equations) and then regularizes the sum over modes by applying a certain analytic procedure. We demonstrate the equivalence of this method with the $ζ-$function scheme. The convergence rate of the mode-sum series is considerably improved here (thus notably reducing computational requirements) by employing an analytic approximation at large $\ell$.

Numerical convergence of physical variables in hydrodynamical simulations of cooling clusters

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Results from hydrodynamical SPH simulations of galaxy clusters are used to investigate the dependence of the final cluster X-ray properties on the numerical resolution and the assumed models for the physical gas processes. Two different spatially flat cosmological models have been considered: a low-density cold dark matter universe with a vacuum energy density Omega_L=0.7 (LCDM) and a cold+hot dark matter model (CHDM). These simulations first include radiative cooling and then also conversion of cold gas particles into stars. When cold gas particles are allowed to convert into stars the final gas profiles show a well defined core radius and the temperature profiles are nearly flat. For the most massive test cluster in the LCDM model, these simulations show a prominent cooling flow in the cluster core. This cluster was analyzed in detail, running simulations with different star formation methods and increasing numerical resolution. A comparison between different runs shows that the results of simulations, based on star formation methods in which gas conversion into stars is controlled by an efficiency parameter c_star, are sensitive to the numerical resolution of the simulation. In this respect star formation methods based instead on a local density threshold, as in Navarro and White (1993), are shown to give more stable results. Final X-ray luminosities are found to be numerically stable, with uncertainties of a factor two.

title: Exploring the diversity of mitochondrion related organelles in Cryptosporidium species
Creators: name: Fung, Shelly Ann
Publisher: name: University of Kent

description: Cryptosporidium is an apicomplexan parasite that causes widespread diarrhoeal disease in both humans and animals. It is a parasite that is responsible for large waterborne outbreaks of Cryptosporidiosis. Humans are thought to acquire the parasite by the ingestion of oocysts, which are shed in the stool of infected animals or humans. Research has been done on this parasite, however up till now there has not been a treatment against this. Cryptosporidium have lost their mitochondrial genome and therefore various mitochondrial pathways have been conserved in some of these species. Using bioinformatics analysis, we summarized the differences and similarities in the metabolic pathways in the mitosomes of six Cryptosporidium species (C. parvum, C. hominis, C. tyzzeri, C. ubiquitum, C.andersoni and C.muris) . As only C. parvum and C. hominis pathways have been mapped on KEGG Pathway Database, amino acid sequences were extracted for proteins involved in glycolysis/gluconeogenesis (map00010), TCA cycle (map00020), protein import machinery (map03060), pentose phosphate pathway (map00030), pyruvate metabolism (map00620) and oxidative phosphorylation (map00190). Amino acid sequences for the protein coding genes were run in BlastP on CryptoDB using the set parameters. The gene results were analyzed and used to produce diagrams to show the metabolic pathways in the mitosomes of the Cryptosporidium species. In this study we show that the essential TCA cycle enzymes were present in the gastric species C. andersoni and C.muris, whereas C.parvum, C.hominis, C.tyzzeri and C.ubiquitum only retain the membrane bound malate-quinone oxidoreductase (MQO) and pyruvate synthase. All species investigated showed a highly reduced protein import machinery in comparison to P.falciparum, and conserved glycolysis/gluconeogenesis proteins and Fe-S (iron-sulfur) cluster assembly, suggesting that these two pathways are the main ways in which the parasite acquires energy. Our results from the CryptoDB Blast search for the Protein Import Machinery and other pathways investigated contained some putative protein coding genes which needs to be experimentally validated. The Tim 9-10 which is responsible for transporting hydrophobic proteins to the inner mitochondrial membrane was annotated as uncharacterized in three protein coding genes: C.hominis (GY17_00000465), C.parvum (cgd6_4450) and C.tyzzeri (CTYZ_00001648). Further studies such as PCR analysis as well as Western blotting can be used to characterize the protein present and molecular structural analysis carried out to find out the shape and immunofluorescent assays as well as neutralization assays used to assess the function of the protein. The results from this study can be helpful to direct further research in understanding the functions of the mitosomes of these species and could be pivotal in developing new therapeutic drugs that are used to target various pathways in Cryptosporidium species.

description: Evidence-based decision making often relies on meta-analyzing multiple studies, which enables more precise estimation and investigation of generalizability. Integrative analysis of multiple heterogeneous studies is, however, highly challenging in the ultra high-dimensional setting. The challenge is even more pronounced when the individual-level data cannot be shared across studies, known as DataSHIELD contraint. Under sparse regression models that are assumed to be similar yet not identical across studies, we propose in this paper a novel integrative estimation procedure for data-Shielding High-dimensional Integrative Regression (SHIR). SHIR protects individual data through summary-statistics-based integrating procedure, accommodates between-study heterogeneity in both the covariate distribution and model parameters, and attains consistent variable selection. Theoretically, SHIR is statistically more efficient than the existing distributed approaches that integrate debiased LASSO estimators from the local sites. Furthermore, the estimation error incurred by aggregating derived data is negligible compared to the statistical minimax rate and SHIR is shown to be asymptotically equivalent in estimation to the ideal estimator obtained by sharing all data. The finite-sample performance of our method is studied and compared with existing approaches via extensive simulation settings. We further illustrate the utility of SHIR to derive phenotyping algorithms for coronary artery disease using electronic health records data from multiple chronic disease cohorts.

description: Infrared (IR) radiation detectors are used in numerous applications from thermal imaging to spectroscopic gas sensing. Obtaining high speed and sensitivity, low-power operation and cost-effectiveness with a single technology remains to be a challenge in the field of IR sensors. By combining nano-thermoelectric transduction and nanomembrane photonic absorbers, we demonstrate uncooled IR bolometer technology that is material-compatible with large-scale CMOS fabrication and provides fast and high sensitivity response to long-wavelength IR (LWIR) around 10 $μ$m. The fast operation speed stems from the low heat capacity metal layer grid absorber connecting the sub-100 nm-thick n- and p-type Si nano-thermoelectric support beams, which convert the radiation induced temperature rise into voltage. The nano-thermoelectric transducer-support approach benefits from enhanced phonon surface scattering in the beams leading to reduction in thermal conductivity, which enhances the sensitivity. We demonstrate different size nano-thermoelectric bolometric photodetector pixels with LWIR responsitivities, specific detectivities and time constants in the ranges 179-2930 V/W, 0.15-3.1$\cdot10^{8}$ cmHz$^{1/2}$/W and 66-3600 $μ$s, respectively. We benchmark the technology against different LWIR detector solutions and show how nano-thermoelectric detector technology can reach the fundamental sensitivity limits posed by phonon and photon thermal fluctuation noise.

title: Signal processing and graph-based semi-supervised learning-based fault diagnosis for direct online induction motors
Creators: name: Kawsar Zaman, Shafi Md
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: In this thesis, fault diagnosis approaches for direct online induction motors are proposed using signal processing and graph-based semi-supervised learning (GSSL). These approaches are developed using experimental data obtained in the lab for two identical 0.25 HP three-phase squirrel-cage induction motors. Various electrical and mechanical single- and multi-faults are applied to each motor during experiments. Three-phase stator currents and three-dimensional vibration signals are recorded simultaneously in each experiment. In this thesis, Power Spectral Density (PSD)-based stator current amplitude spectrum analysis and one-dimensional Complex Continuous Wavelet Transform (CWT)-based stator current time-scale spectrum analysis are employed to detect broken rotor bar (BRB) faults. An effective single- and multi-fault diagnosis approach is developed using GSSL, where discrete wavelet transform (DWT) is applied to extract features from experimental stator current and vibration data. Three GSSL algorithms (Local and global consistency (LGC), Gaussian field and harmonic functions (GFHF), and greedy-gradient max-cut (GGMC)) are adopted and compared in this study. To enable machine learning for untested motor operating conditions, mathematical equations to calculate features for untested conditions are developed using curve fitting and features obtained from experimental data of tested conditions.

description: New concepts of mobility, as part of societal change in form of mega trends, are leading to disruption in the automotive industry. Above all the rise of electric mobility is creating changes in structures within the whole sector supply chain. While still only modestly in use up to now, the majority of automotive sector specific forecasts estimate a market share for electric vehicles of 50% and above by 2030. All major automotive manufacturers invest massively in electric driving concepts. In this context, the brakes are one of the most important pieces of safety equipment on a vehicle. Whereas in internal combustion engine vehicles, the braking system is mostly based on creating abrasion resistance thereby inducing the deceleration, brakes in electric vehicles aim at avoiding the latter. Through regeneration, the electric braking system can convert the kinetic energy previously lost and convert it into electric energy subsequently used for acceleration of the vehicle. This shift in paradigm is causing manufacturers to rethink from the scratch the requirements, possibilities and layout of brake systems. At the same time, the given legislation demands compliance with existing standards that even though presumably outdated, may impede further commercialization of beneficial changes. As a consequence, these developments also have a strong impact on tier 3 suppliers such as producers of additives for friction materials. Aim of this thesis is to provide an overview over the fundamentals of friction braking, regenerative braking and presumably new necessities and challenges, followed by pointing out subsequent implications on friction materials currently in use.

Integrative analysis of multiple heterogeneous studies is, however, highly challenging in the ultra high dimensional setting. The challenge is even more pronounced when the individual level data cannot be shared across studies, known as DataSHIELD contraint (Wolfson et al., 2010). Under sparse regression models that are assumed to be similar yet not identical across studies, we propose in this paper a novel integrative estimation procedure for data- Shielding High-dimensional Integrative Regression (SHIR). SHIR protects individual data through summary-statistics-based integrating procedure, accommodates between study heterogeneity in both the covariate distribution and model parameters, and attains consistent variable selection. Theoretically, SHIR is statistically more efficient than the existing distributed approaches that integrate debiased LASSO estimators from the local sites. Furthermore, the estimation error incurred by aggregating derived data is negligible compared to the statistical minimax rate and SHIR is shown to be asymptotically equivalent in estimation to the ideal estimator obtained by sharing all data. The finite-sample performance of our method is studied and compared with existing approaches via extensive simulation settings. We further illustrate the utility of SHIR to derive phenotyping algorithms for coronary artery disease using electronic health records data from multiple chronic disease cohorts.

description: We investigate quantum phase transitions in the frustrated orthogonal-dimer chain with an arbitrary spin $S \geq 1/2$. When the ratio of the competing exchange couplings is varied, first-order phase transitions occur 2S times among distinct spin-gap phases. The introduction of single-ion anisotropy further enriches the phase diagram. The phase transitions described by the present model possess most of the essential properties inherent in frustrated quantum spin systems.

description: We consider strings with large spin in AdS_3xS^3xM with NS-NS background. We construct the string configurations as solutions of SL(2,R) WZW theory. We compute the relation between the space-time energy and spin, and show that the anomalous correction is constant, and not logarithmic in the spin. This is in contrast to the S-dual background with R-R charge where the anomalous correction is logarithmic.

description: Let $Γ$ be a finite rank subgroup of $\overline{\mathbb{Q}}^*$. We prove that the multiplicative group of the field generated by all elements in the divisible hull of $Γ$, is free abelian modulo this divisible hull. This proves that a necessary condition for Rémond's generalized Lehmer conjecture is satisfied.
description: A serious error was found in the proof of the former Lemma 5.1 which could not be fixed. Since the result concerning elliptic curves in the former Theorem 1.2 was dependent on this lemma, this result and Sections 5, 6, and 7, were removed. The new version now only contains the proof of the result on the linear torus
title: Stimuli-Responsive Polymers Derived from a Visible Light Photoswitchable Species

description: The incorporation of photoswitches into polymeric materials is a favoured method for providing a degree of external control over certain macroscopic properties. Popularly used switches include: azobenzenes, spiropyrans and diarylethenes. However, species like these most often require damaging, high energy UV light for activation, as such visible light activated systems are highly sought after. Donor-Acceptor Stenhouse Adducts (DASAs) are a relatively new class of visible light photoswitches, that exhibit negative photochromism upon activation. These new switches are synthetically accessible and producible under mild conditions with relatively inexpensive reagents. Their large changes in polarity and the ability to almost completely decolourise when exposed to visible light, make them a highly desirable alternative to other more traditional photoswitches. Herein, stimuli-responsive materials were produced through the doping of Sn-catalysed crosslinked polydimethylsiloxane (PDMS) networks with recently discovered visible light photoswitches, DASAs, and precursory species, known as Meldrum's activated furan (MAF). MAF reacts readily with secondary amines to produce a DASA, this synthetic route was exploited by the doping of a crosslinked PDMS network with the precursor molecule (PDMS-MAF). The amine-detection responses were evaluated through UV-Vis spectroscopy, an image analysis technique and changes in RFID sensing values. The applicability of the PDMS-MAF architecture as a colourimetric sensing device was demonstrated by simulation of a food packaging environment. The amine-sensing material was sealed in a container for 24 hours, along with a cod fillet cutting - the presence of decomposition product amines was indicated by a colour change in the material. The doping of a crosslinked PDMS network with a DASA culminated in a photo-responsive material (PDMS-DASA). Crystallisation of DASA at higher concentrations was apparent, encouraging the curing of PDMS-DASA networks in a sealed, solvent-rich environment. Powder X-ray diffraction provided evidence to suggest that the sealed atmosphere curing (SAC) reduced the concentration of crystallisation. The photoswitching kinetics of PDMS-DASA samples were examined using UV-Vis spectroscopy, with a focus on the effect of variation in DASA concentration. Furthermore, initial investigations into photoswitching fatigue, the effect of solvent swelling of photoswitching kinetics and RFID-sensing applicability were conducted. Additionally, other investigations into the covalent incorporation of DASAs for stimuli-responsive polymers are detailed. These further investigations included various polymeric systems, such as polyethyleneimine, poly(methylhydrosiloxane-co-dimethylsiloxane) and building from a polyurea-based scaffold.

description: In dieser Bachelorarbeit wird das Informationsdesign in Videospielen durch die Analyse der Einflüsse von Spielmechaniken auf die Bereiche Tutorialisierung, visuelles User-Interface und Steuerung untersucht. Es werden die Spiele "Dark Souls" und "Stellaris" als gegensätzliche Beispiele herangezogen, um die unterschiedlichen Anforderungen und Herausforderungen des Informationsdesigns aufzuzeigen. Zum Testen der Analyseergebnisse werden die gewonnenen Erkenntnisse in einem Praxisprojekt umgesetzt, bei dem ein eigenes Spielkonzept entwickelt und prototypisch realisiert wird. Die Validierung der theoretischen Annahmen erfolgt durch eine umfassende Nutzerbefragung, deren Ergebnisse zur Evaluation der Effektivität und Benutzerfreundlichkeit des entwickelten Designs herangezogen werden. Ziel der Arbeit ist es, die Wechselwirkungen zwischen Spielmechaniken und Informationsdesign zu verdeutlichen und eine fundierte Grundlage für die Entwicklung zukünftiger Spiele zu schaffen, wobei die Ergebnisse der Nutzerbefragung die theoretischen Überlegungen bestätigen und zur Reflexion des eigenen Designs beitragen.

title: The role of bodily signals in facial expression recognition

description: This thesis examines the role of facial mimicry during tasks of facial emotional expression recognition. The first study examines whether facial proprioception modulates the ability to recognise facial expressions, and/or facial mimicry. Results showed that, although mimicry was detected, participants' recognition ability was not modulated by their facial proprioceptive ability. Study 2 examines whether and how the presence of contextual information that are either congruent or incongruent with emotional facial expressions modulates the accuracy of the recognition of the expression and/or facial mimicry. Study 3 has a similar method and design to the second and includes both clear-cut and low-intensity emotional facial expressions. Taken together, Studies 2 and 3 show that the ambiguity of facial expressions and/or the affective incongruence of linguistic context decreased the recognition ability of happy and angry faces. In the fourth chapter we report two EEG-EMG studies (Study 4 and 5) aimed at examining the relationship between facial mimicry and ERPs associated with emotional processing (EPN and N400). The two studies compare the time-course of these ERPs with that of facial mimicry during a fast valence detection task (Study 4) and an explicit emotional recognition task (Study 5), to examine the interplay between cognitive processes and facial mimicry. The facial expressions used in both studies cover four levels of intensity per emotion. Study 4 involves a valence detection task of rapidly exposed emotional facial expressions. The task of Study 5 measured instead the participant's ability to recognise discrete emotional expressions. Findings from both studies are in line with the hypothesis that N400 is sensitive to the augmented demand of an emotion recognition task. The studies' findings suggest that internal simulation occurs especially in case of increased task demand and develops through a complementary cognitive-peripheral process where mimicry responds selectively in respect to central activity.
