Известно, что любой строительный проект является успешным при условии своей экономической целесообразности на каждом из этапов своего жизненного цикла для этого должны быть налажены процессы автоматизации работы. Современные технологии информационного моделирования открывают новые возможности в оценке эффективности управления объектом. Рассмотрим возможности применения BIM-технологий для автоматизации процессов работы с цифровой информационной моделью (ЦИМ) на этапе подготовки и во время самого строительства, также этапы реализации методики мониторинга и контроля строительного производства на основе современных инновационных технологий и цифровой модели проекта здания.

La présente étude vise à mieux comprendre les trajectoires de vie de travailleuses du sexe indépendantes en s’intéressant au processus d’initiation à l’industrie du sexe, aux variations des pratiques, ainsi qu’aux risques de victimisation et aux stratégies mises en place pour limiter ces risques. Pour ce faire, une méthodologie qualitative a été mobilisée où treize travailleuses du sexe indépendantes ont été amenées à élaborer sur leur trajectoire de vie, de leur enfance jusqu’au moment de l’entretien. Les résultats illustrent des points d’entrée variés et de multiples motivations à offrir des services sexuels rémunérés. Certaines ont commencé en tant que danseuse érotique ou en tant que masseuse érotique, alors que d’autres ont commencé directement en tant qu’escorte indépendante. Si les besoins financiers s’avèrent être un élément influençant leur entrée dans l’industrie du sexe, on remarque qu’il ne permet pas, à lui seul, de maintenir les travailleuses du sexe dans l’industrie. Il y a donc une évolution des motivations au cours de leur trajectoire. Enfin, les risques de victimisation encourus découlent directement de leur relation avec les clients, mais la manière de les filtrer semble limiter considérablement les actes de victimisation. En parallèle, ce mémoire illustre l’amplification de la vulnérabilité des travailleuses du sexe indépendantes en raison de la marginalisation et des mesures législatives qui entourent l’industrie du sexe. / This study aims to better understand the life trajectories of independent sex workers by focusing on the process of initiation into the sex industry, the variations in practices, as well as the risks of victimization and the strategies implemented. to limit these risks. To do so, a qualitative methodology was mobilized where thirteen independent sex workers were led to elaborate on their life trajectory, from their childhood until the moment of the interview. The results illustrate varied entry points and multiple motivations for offering paid sexual services. Some started as an erotic dancer or as an erotic masseuse, while others started directly as an independent escort If financial needs prove to be an element influencing their entry into the sex industry, we note that it does not, on its own, allow sex workers to remain in the industry. We therefore observe an evolution of motivations during their trajectory. Finally, the risks of victimization incurred stem directly from their relationship with the clients, but the way of filtering them seems to considerably limit the acts of victimization. In parallel, this thesis illustrates the amplification of the vulnerability of independent sex workers due to the marginalization and legislative measures surrounding the sex industry.

Målet med projektet var att undersöka samt implementera en fysikbaserad DFN modell för att simulera kalender samt cyklingåldrande av litiumbatterier som används i elbilar. Den fysikbaserade modellen var konstruerad baserad på ett Python biblioteket vid namn PyBaMM, vilket till skillnad från datadrivna modeller ger essentiell information om de kemiska processerna inuti batteriet. Den första delen av projektet täcker konceptet av kalenderåldring, vilket inkluderar en jämförelse mellan tre olika tre olika hastighetsbegränsande SEI modeller. Parametrar som påverkar det erhållna resultatet från modellen är identifierade, estimerade, och till slut validerade för att säkerhetsställa att modellen och parametrarna är identifierbara gentemot experimentella data. Resultatet av jämförelsen gav att SEI tillväxt begränsad av litium interstitiell diffusion är den mest optimala modellen att applicera när kalenderåldring för litiumbatterier ska modelleras. Resultaten visade också att endast en parameter, inre SEI litium interstitiell diffusivitet ska justeras för att erhålla optimal anpassning mot experimentella data. Andra delen av projektet använde resultatet från den första delen och litium plätering implementerades som en andraåldringsmekanism som undersöktes under tre olika laddningsprotokoll. Modellen var optimerad och anpassad gentemot experimentella data, där parametervärdet för kinetisk hasighetskonstanten för plätering var estimerad. Den optimerade modellen användes därefter för att erhålla mer information om elektrokemiska variabler för att kunna analysera samt beskriva åldringsprocessen utan att behöva genomföra praktiska laborationer. Resultaten visade att mängden pläterat litium på den negativa elektroden ökade för celler som var exponerade till högre ström under laddningsprocessen, samt när cellerna var laddade vid höga SoC nivåer. Sammanfattningsvis, visade modellen hög potential att representera och evaluera experimentella data, samt tillhandahålla en inblick i elektrokemiska processer och kapacitetsförluster länkade till SEI tillväxt och litium plätering. Däremot, för att erhålla en högre grad noggrannhet av elektrokemiska åldringsmekanismer i litiumbatterier, fler ytterligare mekanismer måste implementeras såsom mekanisk stress av både negativ och positiv elektrod. / The aim of this study was to investigate and apply a physics-based DFN model to simulate the calendar and cycling ageing of lithium-ion batteries manufactured for EV applications. The physics-based cell ageing model was constructed based on the open-source software Python library PyBaMM, which in comparison to data-driven models provides more essential information about the chemical process within the battery cell. The first part of the project covers the concept of calendar ageing which includes comparisons between three different rate-limiting SEI growth models. Parameters that affect the output from the physics-based model are isolated, estimated with numerical methods, and lastly validated to ensure that the model and the parameters rep- resent the physics behind the experimental data. It was found that the SEI growth limited by lithium interstitial diffusion is the most optimal model to apply for a physics-based model when modeling calendar ageing. It was also found that the only parameter that should be tuned against experimental data is the inner SEI lithium interstitial diffusivity. The second part of the project utilizes the results from the first part and introduces lithium plating as a second cell ageing mechanism under three different charging protocols. The model was optimized and fitted against experimental data by sweeping the lithium plating kinetic rate constant parameter. The optimized model was thereafter used to generate outputs that more thoroughly can explain the degradation effects of the cell without constructing real-world experiments. Where increased rate of plated lithium could be observed for the cell subjected to higher charging C-rate, and when the cells were charged at high SoC levels. To summarize, the model showed great potential in representing and evaluating the experimental data and providing the project with insight into the electrochemical processes and cell capacity losses of SEI growth and lithium plating. However, in order to achieve a higher accuracy of cell ageing model in relation to the lithium-ion cells used in customer vehicles, several additional cell degradation mechanisms have to be introduced, such as mechanical degradation of the two electrodes.

This diploma thesis covers the individual citizens' perception of suburban events in order to discuss the point of view of the early modern Czech citizen and their ability to gain information of the world around through the analysis of such suburban events that were registered in the chosen chronicles, originating between the years 1575-1600, a period that is considered "a golden age of the Czech cities". First, the background of the chroniclers is outlined, because it might have influenced the choice of events they decided to include in their works, i.e. the position of the concrete city, the level of education in the said period or the author's personal life. Second, the general knowledge of the authors is described in the thesis through the means of analysis of the type of recorded information (e.g. Turkish wars, the deaths of famous persons, wildfires, councils and the like). In other words, the thesis is to point out what type of information was considered to be the most interesting or extraordinary to the wider public, and which circles were usually covered by the chroniclers. Therefore, the reader is to discover the world of thought of the early modern citizen, which has been restricted to us because of the lack of other than administrative materials, and the impulses that influenced and...

Subject: Active senior lifestyle Author's name: Bc. Iveta Dušková Supervizor: profesor Ing. Václav Bunc CSc. Objective: To verify whether biological age of tested seniors is in line with their calendar age. The differnce towards calendar age will be evaluated via ECM/BCM ration based on body content analysis. I will investigate the influence of physical activity on slower ageing physiology and the effect of physical activity on status of net muscle mass and on frequency of civilazation diseases. The goal is to figure out if active lifestyle is available also for seniors. Methods: The core of the work is qualitative and quantitative survey mapping antropometric parameters by bioimpedancy method. The functional values were collected by motorical step est and by handgrip. Further the subjective quality life judgment interview with yes/no options was used for the target senior group. Results: The relationship was found for the bioimpedancy results and the the volume of physical weekly activity (in hours) and level of BMI and pecentage of body fat. Further the realtionship was found for physical activity volume and for the dynamometric and motorical test results. Thjere is a difference between men and women. There was no relationship found for ECM/BCM coefficient and physical activity volume. The type...

Dans un contexte de progression du stockage d’énergie sous forme électrochimique dans les transports, notamment dans l’aéronautique, les problématiques de performance, de fiabilité, de sureté de fonctionnement et de durée de vie du stockeur sont essentielles pour utilisateurs. Cette thèse se focalise ces voltes pour l’avion plus électrique. Les technologies étudiées correspondent à des éléments commerciaux de dernière génération de type Lithium-ion (NMC/graphite+SiO, NCA/graphite, LFP/graphite, NMC/LTO), Lithium-Soufre (Li-S), supercondensateur et hybride (LiC). Une première partie de ce manuscrit s’attache à la quantification des performances des différents éléments dans l’environnement aéronautique [-20°C, 55°C] et pour l’usage aéronautique. Un modèle comportemental de type électro-thermique est développé et validé. La seconde partie est consacrée à la quantification du vieillissement des différents éléments. Les résultats de vieillissement calendaire et en cyclage actif sont présentés ainsi que ceux des tests abusifs. Une méthode d’estimation de l’état de santé (SOH) des éléments basés sur l’analyse de la capacité incrémentale (ICA) est proposée. Enfin, l’évaluation de la robustesse des éléments de stockage lors de tests de vieillissement accéléré avec un profil spécifique à l’usage aéronautique est proposé. Les modèles de vieillissement et la méthode d'estimation de SOH proposés précédemment sont utilisés ici pour évaluer l'impact de la température sur la vitesse de dégradation et pour estimer le SOH des cellules vieillies à l’aide de ce profil aéronautique. / In the context of progress in the electrochemical energy storage systems in the transport field, especially in the aeronautics, the issues of performance, reliability, safety and robustness of these elements are essential for users. This thesis is focused on these issues for the more electric aircraft. The technologies studied correspond to the latest generation commercial elements of Lithium-ion batteries (NMC/ graphite + SiO, NCA/graphite, LFP/graphite, NMC/LTO), Lithium-Sulfur (Li-S), Supercapacitor and Lithium-ion capacitors. The first part of this manuscript is dedicated to the performance quantification of the different electrochemical energy storage elements in aeronautical environment [-20°C, 55°C] and usage. An efficient and accurate electro-thermal model is developed and validated. The second part is devoted to the calendar and power cycling ageings as well as to the presentation of abuse testing results. A State Of Health (SOH) estimation based on incremental capacity analysis method is proposed. Finally, the robustness of the storage elements during accelerated ageing tests with a specific profile for the aeronautical usage is evaluated. The ageing models and SOH estimation methods proposed in the previous sections are used here to evaluate the impact of temperature on the degradation rate and to estimate the SOH of the cells with this aeronautical profile.

The first part is devoted to the modeling of lithium batteries with an equivalent electric circuit model, whose parameters could be identified using linear characterization tests. The second part is dedicated to the study of aging, and results in an aging estimator using data collected from accelerated aging tests programs. Then the postal usage is studied, and a power profile representative of the actual load on the battery is provided. The latter was used to validate the model of the battery in the field of postal use. Then the postal use is studied, and a current profile representative of the real behavior of the battery is provided. This profile was used to validate the model of the battery in the postal use domain. Then a model of electric vehicles is presented, it integrates the battery model, which can simulates the aging state of the battery using the ageing estimator. Finally, the various possible strategies of recharge are listed and compared, which leads to conclusions about their influences on aging of batteries, and the vehicles performance.
