Dysphagia is a serious eating disorder currently affecting around 100 thousand people in Sweden and it’s estimated that 1 in 10 people will develop some form of dysphagia during their lifetime around the world. The condition occurs mainly in elders and people who’ve suffered a stroke. The disorder prohibits proper swallowing of food, impairing the ability to close airways and let food enter the proper pathways. Patients with dysphagia have to eat grounded food in order to not suffer from malnutrition. The food is usually served in timbales which are sometimes decorated but might not look as appealing or realistic as one might think. The repetitive and unrealistic food creates further appetite loss which may lead to malnutrition. This is the case amongst many elderly in home care and the complications maybe very serious indeed, leading to organ dysfunction, hospitalization and eventually death. The current timbales made at the kitchens for elderly care in Helsingborg are punched with a tool in rectangular, circular shapes and often decorated. A solution would be to increase the aesthetics of the served timbales and make them realistically looking. 3D printing offers numerous new opportunities for food production and may very well set a standard in the future for producing aesthetically pleasing food. Silicone molds may also provide the same, if not better results at the time being at a fraction of the price, sufficing to revert any negative impacts of the current timbale appearance. In the hopes of proving both concepts the work will initially be focused on preparing a broccoli but also applying one of the concepts on a cinnamon bun providing additional application. This report presents the progress of designing a realistic 3D broccoli model, product development of a realistic broccoli food mold, 3D scanning, 3D food printing and a literature study. The designed model could not be printed due to the printing gel’s incapability of supporting complex structures. Instead master shapes created for shaping the food mold were scanned, sliced and printed. The same masters were used as means for a second food mold. Both food molds did manage to cast realistic shapes with a broccoli puré and of a soft gelatine suspension. Material alternatives were evaluated as well as manufacturing possibilities. The designed broccoli and a refined scanned broccoli were both offered for free as means for further research and development.

In that sense, the<br />position of &bdquo;feminine&ldquo; is constructed and<br />labeled as &bdquo;the other&ldquo;, the figure reflecting<br />prevailing social relations. Thus, woman is a<br />category and things attributed to this category,<br />i.e. to the feminine principle, are other, secondrated,<br />unwelcome, less worth within the<br />dominant ideologies and media practices typical<br />for them. One of the issues I deal with in this<br />work is the research on whether the new media<br />technologies and new forms of communication<br />and conveying media content, as well as the<br />dynamic relationship between media contents<br />and media audiences, contribute to the change<br />of representing and constructing feminine<br />identities in media discourses, or they just<br />repeat the patriarchal discriminatory patterns in<br />a new media setting.<br />Aim of the research is to show how different<br />identities of women are being constructed in the<br />representation practices of the online editions<br />of the printed media, as well as to determine if<br />these media practices include the strategies of<br />excluding women through certain constructions<br />of reality, ghettoization and stereotyping of<br />women in the media, and if they do, to examine<br />how these strategies work.<br />Methodological framework of the research<br />&bdquo;Gender Analysis of the Online Editions of<br />Printed Media in Serbia&ldquo; includes combination<br />of quantitative and qualitative approaches to the<br />process of proving hypotheses &ndash; one general<br />and three specific hypotheses derived from the<br />general one.<br />General Hypothesis<br />Unrelated to the global transformation of media<br />genres and ways of communication, female<br />identity in the contemporary transitional society<br />of Serbia is always represented as &bdquo;the other&ldquo;<br />and through &bdquo;otherness&ldquo;, regardless of the<br />position an identity has in the social distribution<br />of power.<br />Hypothesis 1<br />In the media discourse there is uneven<br />distribution of power and visibility of different<br />female identities (women from the public sphere<br />vs. marginalized women).<br />Hypothesis 2<br />Media texts recognize the subject of violence<br />against women as the crucial subject of the lives<br />of women, i.e. it is crucial in the media<br />representations of women in the social context &ndash;<br />and the majority of women are presented as<br />victims.<br />Hypothesis 3<br />Women from minority and marginalized groups<br />are invisible in the media discourse of the online<br />editions of printed media.<br />Hypotheses were tested through the research<br />based on monitoring online editions of the<br />printed media (texts and comments of readers):<br />four national &ndash; Blic, Politikа, Kurir, Dаnаs, and<br />one local &ndash; Dnevnik from Novi Sad.

Un modèle analytique complet est développé. Des prototypes sont réalisés, validant le modèle et démontrant l’intérêt de la topologie.L’agencement des composants de puissance constituant une cellule de commutation est ensuite étudié. En particulier, un modèle analytique permettant une compréhension intuitive des mécanismes oscillatoires dans le cadre de l’emploi de transistors rapides est décrit.Une technique de reprise de contact de face avant pour puce enfouie, basée sur un morceau de mousse pressée, est proposée.

A comprehensive analytical model is developed. Prototypes are manufactured, validating the analytical model and highlighting the value of the topology.The arrangement of the power components of a switching cell is then studied. In particular, an analytical model offering an intuitive understanding of the oscillation mechanisms in cells using fast transistors is proposed.A simple and economical top-side connection technic for PCB-embedded power dies using a pressed piece of metal foam is described.

Les énergies fossiles (Pétrole, Charbon, …) représentent 80 % des énergies consommés. Malheureusement pour l’environnement, elles sont les plus polluantes. Le remplacement actuel des énergies fossiles permet au marché de l’électronique de puissance de grandir d’année en année. L’électronique de puissance permet d’adapter l’énergie électrique à son utilisation finale. Dans la pratique, l’adaptation de l’énergie électrique utilise des convertisseurs. En plus de respecter le volume, l’efficacité et la fiabilité imposés par le cahier des charges pour chaque application, l’électronique de puissance doit aussi permettre de réduire sensiblement les coûts. Le convertisseur doit assurer le fonctionnement électrique du circuit, le support mécanique des composants et la gestion thermique. Le package utilisé par les nouveaux composants à grand gap limite leurs performances. L’intégration des convertisseurs doit développer des méthodes d’interconnexion permettant d’éliminer ce package. L’objectif de la recherche sur l’intégration des convertisseurs est de repousser les limites imposées par un cahier des charges standard tout en assurant ces 3 fonctions principales. Parmi les nombreuses techniques d’intégration, le circuit imprimé (PCB) est mature industriellement, permet la fabrication collective et un assemblage automatisé. L’intégration utilisant le PCB a développé la technique d’enfouissement de puce avec laquelle la puce est directement enfouie dans le PCB sans son package. Cette thèse va étudier la méthode d’enfouissement pour les autres composants nécessaires à la réalisation d’un convertisseur (Condensateurs, Composants Magnétiques). Une optimisation du convertisseur qui doit être réalisé permet de prendre en compte les avantages de cette nouvelle technologie. Un prototype de convertisseur intégré a été réalisé avec des composants utilisant cette technologie. / With the endangering of the environment due to the use of fossil fuels, the power electronics market is growing through the years. The number of applications is increasing in numerous field as, for example, transport (electric car, "more electric" aircraft) or energy (photovoltaic, smart grid). Beyond meeting the volume, efficiency and reliability specifications for each application, power electronics should also reduce substantially costs. Today, the managing of the electric energy uses power electronic converters. The conception of a converter is a multiphysic problem. The converter has to ensure electrical functionality, mechanical support and proper thermal management.The new wide-band gap components are limited in performance by their package. The integration of a converter should use new interconnection methods to avoid the use of packaged components. The trend is to integrate the maximum of components into a single system. This integration can offer benefits such as size and weight reduction, cost saving and reliability improvement by managing the complexity and the high density of interconnection. Among many integration technologies available, Printed Circuit Board (PCB) is well known in the industry, allowing mass production with automated manufacturing and assembly. The PCB integration was developed with the “Die Embedding” technology in which a bare die in embedded directly in the PCB to not use package. This thesis studied the embedding technology on others components necessary to the realization of a converter (Capacitors, Magnetics, …). An optimization of the converter is done taking into account the advantages of this new technology. A prototype of an AC/DC bidirectional converter fully integrated using this technology was realized.

The thesis describes the transposition of the Czech Television crisis on the pages of daily newspapers and weekly magazines. The theoretical part of the thesis describes the genesis of the TV crisis and later shows the problematic of biased news. In the practical part it divides the Czech media according to the quantitative content analysis to the media which openly supported the rebelling journalists or the new management of Czech TV. Interesting in the study is that the traditional right-left division of the Czech media was disproved in the analysis, because the Socialist Party was speaking frequently and with biggest weight also in the traditional right-wing daily newspapers such as Hospodarske noviny, Lidove noviny and Mlada fronta Dnes.

<div>Additively manufactured (AM) metals have been increasingly fabricated for structural applications. However, a major hurdle preventing their extensive application is lack of understanding of their mechanical properties. To address this issue, the objective of this research is to develop a computational model to simulate the creep behavior of nickel alloy 718 manufactured using the laser powder bed fusion (L-PBF) additive manufacturing process. A finite element (FE) model with a subroutine is created for simulating the creep mechanism for 3D printed nickel alloy 718 components.</div><div><br></div><div>A continuum damage mechanics (CDM) approach is employed by implementing a user defined subroutine formulated to accurately capture the creep mechanisms. Using a calibration code, the material constants are determined. The secondary creep and damage constants are derived using the parameter fitting on the experimental data found in literature. The developed FE model is capable to predict the creep deformation, damage evolution, and creep-rupture life. Creep damage and rupture is simulated as defined by the CDM theory.</div><div>The predicted results from the CDM model compare well with experimental data, which are collected from literature for L-PBF manufactured nickel alloy 718 of creep deformation and creep rupture, at different levels of temperature and stress. </div><div><br></div><div>Using the multi-regime Liu-Murakami (L-M) and Kachanov-Rabotnov (K-R) isotropic creep damage formulation, creep deformation and rupture tests of both the secondary and tertiary creep behaviors are modeled.</div><div>A single element FE model is used to validate the model constants. The model shows good agreement with the traditionally wrought manufactured 316 stainless steel and nickel alloy 718 experimental data collected from the literature. Moreover, a full-scale axisymmetric FE model is used to simulate the creep test and the capacity of the model to predict necking, creep damage, and creep-rupture life for L-PBF manufactured nickel alloy 718. The model predictions are then compared to the experimental creep data, with satisfactory agreement.</div><div><br></div><div>In summary, the model developed in this work can reliably predict the creep behavior for 3D printed metals under uniaxial tensile and high temperature conditions.</div>

This thesis deals with principles of thermochromism and its possible applications in heat distribution testing. Theoretical part describes mechanisms which allow the thermochromic properties of the substances. Particular attention is paid to cholesteric liquid crystals. Ability to measure the heat for this type of liquid crystals was varified. Also long service life in high humidity environment, enviroment with intense UV radiation, cyclic changes in temperature or immersion in water was tested. A possibility of their practical use in diagnosis was verified as well. Specifically mapping of heat distribution on an assembled PCB. Conclusion contains comparison and evaluation of this method in terms of accuracy, user comfort and economic advantages compared to conventional infrared sensors.

This diploma thesis is studing the possibilities of influencing the optoelectric properties of printed light emitting panels, which work on the principle of electroluminescence excited by alternating electric field. The aim of this worrk is to monitor the influence od dielectric properties of electroluminescent phosphor binder on the targeted electroluminescence. In the theoretical part of this thesis, there are described principles of electroluminescence, suitable materials methods of characterization and preparation of panels using printing techniques. Experiment part contains electrical characterization of selected binders to determine their dielectric constants. Subsequently, printing pastes were formulated in different weight ratios of binder electroluminescent phosphor and model light-emitting panels were prepared. Optoelectric characterization was used to determine the change in irradiance. It was found that the dielectric properties of the binder significantly affect the resulting irradinace. It has same irradiance for a smaller amount od phosphor than with the binder with a low dielectric constant. The finding of this work can be used to improve the luminosity at the electroluminescent panels.

Organické elektronické zariadenia sú vyvíjané ako vhodné riešenia senzorov pre bioelektroniku, a to najmä kvôli dobrej biokompatibilite organických polovodičov v nich použitých. Takzvané biosenzory dokážu premeniť elektrochemické procesy na elektronický signál. Matrica takýchto biosenzorov môže simultánne skenovať množstvo biologických vzoriek, alebo rôznych tkanív v živých systémoch. Aktívnou súčasťou zariadenia je organický elektrochemický tranzistor (OECT). V tejto práci je diskutovaný teoretický rámec fungovania takéhoto zariadenia, jeho elektrická charakterizácia, aplikácia v biosenzoroch na báze buniek, spôsoby výroby a aktuálnym stavom techniky v oblasti organickej elektroniky. Experimentálna časť obsahuje konkrétne výrobné postupy vývoja OECT zariadení, ktoré boli použité v našom laboratóriu. Hlavný dôraz sa kladie na schopnosť vyrobených zariadení detekovať reakciu a monitorovať stimuláciu elektrogenných buniek. Za týmto účelom boli vyvinuté matice mikroelektródových OECT zariadení založených na polovodivom polyméri PEDOT:PSS. Tieto boli vyrobené s využitím bežnými tlačiarenských techník (atramentová tlač a sieťotlač) spolu so štandardnými litografickými postupmi. Najnovšie nami vyvinuté zariadenia dosahujú najväčšieho zosílením signálu, g = 2,5 mS a časovú konštantu t = 0,15 s. Tieto zariadenia sú porovnateľné, často dokonca lepšie ako niektoré iné najmodernejšie a plne litograficky pripravené senzory.

The Master's thesis discusses the design and realization of electronic meter of volt-ampere characteristics using Wifi module ESP32. The device is designed to be able to measure the characteristic in the voltage range of +/- 20 V and current range of +/- 200 mA. The device is controlled by web interface. The user is able to connect to it with for example his or her smartphone. This interface enables the user to configure various parameters, including the range of measurement and the power restriction. Furthermore, it is possible to graphically display the measured characteristic and export the data. To be independent on the outer network, the ESP32 is operated as an access point, which is creating a new simple network without the internet connection. In the Master's thesis, the principle of voltage and current measurement is explained theoretically, the circuit connection of device and the printed circuit board are designed and the cover of the device is modeled. Also the process of creating the device according to the design is described and the cover of the device is printed on 3D printer. After that, the control program is designed, described and uploaded into the resulting device. Finally, the functionality of the device is tested by measuring the volt-ampere characteristics of a few components.
