Förändringar sker ständigt i organisationer av olika anledningar och som konsekvens av covid19 har distansarbete under den senaste tiden haft en snabb ökning, då många arbetsplatser tvingades ställa om till detta för att begränsa smittspridningen. Nya direktiv kom snabbt och förutsättningarna kunde ändras från dag till dag. Arbetet på distans resulterade i en ökad digitalisering och ledarskapet på plats fick i många fall skötas på distans och från det egna hemmet via en mobiltelefon eller dator. Flera faktorer påverkar ledares kommunikation och relationer till sina medarbetare och i föreliggande studie kommer fokus ägnas åt hur distansarbete som en förändring påverkat medarbetare och arbetsgrupper ur ett ledarskapsperspektiv. Vi har utfört en kvalitativ studie som undersökt de nya förutsättningarna och hur de påverkat kommunikation och relationer. För studien har vi genomfört nio semistrukturerade intervjuer med ledare inom kultur och fritidsenheten på olika kommuner som innan covid-19 inte arbetat så mycket på distans. Vår studie handlar om hur ledare upplevt denna tid och om de sett någon påverkan på relationer och kommunikation med medarbetarna, de har fått anpassa sig till nya arbetssätt och funnit nya strukturer.  Syfte och metod: Studiens syfte har varit att öka förståelsen för den upplevda förändringen och de upplevda möjligheter och svårigheter som kommit med att hålla relationer och kommunikation digitalt. LMX är den teori som beskriver relationens betydelse mellan ledare och medarbetare. Teorin används för att ge en teoretisk grund för det material som studien presenterar. Då studiens ska ge en djupgående beskrivning av det valda problemområdet är studien baserad på en kvalitativ metod. Studien baseras på nio semistrukturerade intervjuer med ledare som arbetar i kommunal verksamhet som ger sina upplevda tankar kring ämnet. Intervjuerna genomfördes i form av videosamtal med samtliga respondenter med hänsyn till rekommendationerna om social distansering. Resultat och slutsats: Studiens resultat visar utifrån det empiriska materialet och teorin att relationer som tidigare fungerat bra i stor grad fortsätter att fungera bra även vid ett distansledarskap. Kommunikationen har kunnat utvecklas med digital hjälp och det har funnits substitut till fysiska möten via digitala plattformar. Studiens viktigaste slutsats är att mycket tid får läggas på de relationer med medarbetarna som inte fungerat fullt ut, de relationer som är krävande från start blir inte mindre krävande i en tvingande förändring. / Background and problems: Changes are constantly taking place in organizations for various reasons and as a consequence of covid-19, teleworking has recently increased rapidly, as many workplaces were forced to switch to this to limit the spread of infection. New directives came quickly and the conditions could change from day to day. The work at a distance resulted in increased digitization and the leadership on site had in many cases had to be managed remotely and from one's own home via a mobile phone or computer. Several factors affect leaders' communication and relationships with their employees, and in the present study, the focus will be on how teleworking as a change has affected employees and workgroups from a leadership perspective. We have conducted a qualitative study that examined the new conditions and how they affected communication and relationships. For the study, we conducted nine semi-structured interviews with leaders in the culture and leisure unit in different municipalities who before covid-19 did not work that much at a distance. Our study is about how leaders experienced this time and if they saw any impact on relationships and communication with employees, they have had to adapt to new ways of working and found new structures. Purpose and method:The purpose of the study has been to increase the understanding of the perceived change and the perceived opportunities and difficulties that have come with keeping relationships and communication digital. LMX is the theory that describes the importance of the relationship between leader and employee. The theory is used to provide a theoretical basis for the material that the study presents. As the purpose of the study is to provide an in-depth description of the selected problem area, the study is based on a qualitative method. The study is based on nine semi-structured interviews with leaders who work in municipal activities who give their perceived thoughts on the subject. The interviews were conducted in the form of video interviews with all respondents concerning the recommendations on social distancing. Results and conclusion: The results of the study show, based on the empirical material and theory, that relationships that previously worked well to a large extent continue to work well even at a distance leadership. Communication has been able to be developed with digital help and there have been substitutes for physical meetings via digital platforms. The most important conclusion of the study is that a lot of time may be spent on the relationships with employees that have not worked fully, the relationships that are demanding from the start will not be less demanding in a compelling change.

Depending on the observed values a technical solution was created in variations and applied in the calculation program.

This diploma thesis deals with dynamic analysis of the steam turbine blade. This blade is part of the last row of low pressure level of steam turbine. Computational analysis has been performed in first part using FEM and software ANSYS. A Transient analysis has been used to solve forced vibrations. Main goal is to obtain a behavior of main stresses and its directions as a function of loading of the blade in the crack initiation area. Second part deals contain a an experiment. Experiment has been set up to perform a modal analysis which is necessary to obtain a fundamental numbers. Then the vibration of the blade has been performed. To perform this experiment same edge conditions as which has been used during the computational analysis. Goal is the same as in the first part – obtain a behavior of main stresses and its directions as a function of loading of the blade in the crack initiation area. The comparison of results obtained during experimental analysis and computational analysis has been performed in the last part of the thesis. Also the question if any geometrical nonlinearities appeared during analyses is answered.

The recent uprise of end-to-end speech translation models requires a new generation of parallel corpora, composed of a large amount of source language speech utterances aligned with their target language textual translations. We hereby show a pipeline and a set of methods to collect hundreds of hours of English audio-book recordings and align them with their Italian textual translations, using exclusively public domain resources gathered semi-automatically from the web. The pipeline consists in three main areas: text collection, bilingual text alignment, and forced alignment. For the text collection task, we show how to automatically find e-book titles in a target language by using machine translation, web information retrieval, and named entity recognition and translation techniques. For the bilingual text alignment task, we investigated three methods: the Gale–Church algorithm in conjunction with a small-size hand-crafted bilingual dictionary, the Gale–Church algorithm in conjunction with a bigger bilingual dictionary automatically inferred through statistical machine translation, and bilingual text alignment by computing the vector similarity of multilingual embeddings of concatenation of consecutive sentences. Our findings seem to indicate that the consecutive-sentence-embeddings similarity computation approach manages to improve the alignment of difficult sentences by indirectly performing sentence re-segmentation. For the forced alignment task, we give a theoretical overview of the preferred method depending on the properties of the text to be aligned with the audio, suggesting and using a TTS-DTW (text-to-speech and dynamic time warping) based approach in our pipeline. The result of our experiments is a publicly available multi-modal corpus composed of about 130 hours of English speech aligned with its Italian textual translation and split in 60561 triplets of English audio, English transcript, and Italian textual translation. We also post-processed the corpus so as to extract 40-MFCCs features from the audio segments and released them as a data-set.

The rapid antidepressant effect of ketamine changed the direction of the research of potential antidepressants and its effect was also evaluated in this thesis. However, the main focus of this thesis is a new methodological approach to the research of depressive disorder. The main interest lies with the evaluation of automated monitoring of behaviour in this research. The first aim of this thesis was to evaluate the antidepressant effect of ketamine in the forced swimming test using software enabling automated monitoring of behaviour. The second aim was to meassure the change in phosphorylated Mammalian target of rapamycin (mTOR), using Enzyme-Linked ImmunoSorbent Assay (ELISA). The last, but the most important aim of this thesis was to implement the utilization of Phenotyper boxes in the automated behavioural evaluation of the olfactory bulbectomy model of depressive disorder and also evaluate the effect of ketamine in this model. Ketamine did not show an antidepressant effect in forced swimming test, however this observation could be influenced by chosen dose and mouse strain. Sensitivity of the test to chosen experimental protocol shows insufficient validity of this test. Observed change in level of phosphorylated mTOR corresponded with the behavioural results. Data collected from Phenotyper...

Dropwise condensation, which collects the condensate liquid in the form of droplets, has attracted a growing interest due to much higher heat transfer coefficient. One important and challenging issue in dropwise condensation is the presence of non-condensable gas (NCG) which drastically reduces its heat transfer performance. Concerning the mechanism understanding, this thesis is aiming to investigate dropwise condensation in case of NCG by combing different methods. Firstly, convective dropwise condensation out of moist air is experimentally investigated under controllable conditions. In modeling, some crucial aspects are reasonably captured: the coupled heat and mass transfer during droplet growth by a multi-scale droplet growth model; the inter-droplet interaction defined by a distributed point sink method; the enhancement of the convective mass transfer using the droplet Sherwood number. Furthermore, a multi-component multi-phase thermal pseudopotential-based LB model is developed to advance the directly numerical simulation of dropwise condensation.

This master thesis deals with a study of forced migration from the Chechen republic during Chechen wars in 1996-2002. The aim of the paper is to contribute to the study of migration strategies of refugees from Chechnya. This qualitative study attempts to grasp the complexity of forced migration process and to depict it from the perspective of refugees. It explores motives and strategies of mobility of the Chechen refugees now living in Russia and Austria and of those refugees, who have returned to Chechnya after the war was over. The impact of this armed conflict on population mobility was examined with a qualitative research of sixteen refugees, who had left Chechnya because of the war. The results of the research show the link between refugee's age and likelihood of return, differences in decision-making of Chechen and Russian refugees, and the strong influence of the social networks on the decision-making and after arrival at destination. Key words Chechnya, forced migration, reasons for migration, destinations, returns, qualitative approach
