The theoretical part introduces regulation reserve that are used by transmission system operator to balance power imbalances. In the next part is made introduction to the system state classification and knowledge of European Network of Transmission System Operators for Electricity about unsolicited disconnection of photovoltaic plants. The theoretical part of the recommendations and simulations is followed by a part of the work in which the analysis of the implementation of the frequency boundary in which the photovoltaic power plants are operated in selected states of synchronously interconnected Europe. The master thesis continues to explain the origin of power imbalances by introducing a theory of electricity trading. Deterministic frequency deviations are one of the causes of the occurrence of frequent imbalances in the system and are discussed in the following chapter together with a proposal for a possible solution. In the last part of the master thesis are presented simulations that were made to determine the impact of the speed control regulator in the Czech Republic on unsolicited disconnection of photovoltaic power plants.

Consequently, divorce has become more accepted, although adolescents from divorced families are considered at risk for maladjustment. The aim of this study is to give a voice to adolescents who have experienced their parents' divorce and to highlight their resilience despite the challenges they faced. The epistemological framework is social constructionism. In-depth interviews with two adolescents who have experienced the divorce of their parents were undertaken. The method of analysis used was `Thematic content analysis'. The participants' stories were recounted through the lens of the researcher in the form of themes. Recurring themes in these stories were elucidated and linked with the literature. This study allowed rich and detailed descriptions about adolescents' experiences to emerge, which the researcher hopes will broaden the therapeutic understanding of the complexities of divorce for the adolescents who survive it. / Psychology / MA (Clinical Psychology) Adjustment Adolescence Boundaries Connection Coping Disconnection Divorce Epistemology Loss Maladjustment Qualitative research Postmodernism Research methodology Resilience Silence Social constructionism Thematic content analysis. 306.890835 Divorce -- Psychological aspects Social work with teenagers Life change events Divorce -- Case studies Adolescent psychology Adjustment (Psychology) in adolescence Stress in adolescence Interpersonal relations in adolescence Adolescent psychotherapy Separation (Psychology)

54	Skolgårdens plats i den föränderliga staden / The place of the school ground in the transformative city Hansson, Sanna, Lundeberg, Sonja January 2021 (has links) I stadens förändringsprocess, ständigt präglad av nya ideal, ska många intressen förenas och beaktas vid utformningen av skolgårdar. Med utgångspunkt i naturens betydelse för barns hälsa och utveckling undersöker denna studie två skolgårdar i Malmö utifrån tre perspektiv: skolgårdarnas utformning, högstadieelevers användning av och preferenser på skolgården samt planerarens prioriteringar och tillvägagångssätt vid utformningen av skolgårdsmiljöer. Syftet är, genom förståelse för hur dessa tre perspektiv kan förenas, öka kunskapen kring hur skolgårdarna kan planeras mer socialt och ekologiskt hållbart i den föränderliga staden. Detta undersöks med en mixad metod genom platsobservationer, enkätundersökningar och intervjuer. Empirin påvisar en relativt passiv inställning till skolgården bland eleverna, oberoende av skolgårdens storlek och mängd grönska samt att de överlag prioriterar social interaktion och mobilanvändande på rasterna. Tolkningen av det empiriska materialet utifrån teorin tyder på att det är grönskans kvalitet som påverkar elevernas intresse för att ta del av miljön. Genom intervjuerna framkom det att utformningen av ett grönt ramverk som erbjuder olika rumsligheter kan bidra till en mer jämlik, inkluderande och hållbar skolgårdsmiljö. Den ideala skolgårdsmiljön, som kan anses vara en där naturen företräds, speglar dock inte nödvändigtvis elevernas uppfattning av den ideala skolgården. Elevernas preferenser kan däremot få ta plats inom det hållbara ramverket, genom aktiv gestaltning. / Within the city's transformative process, constantly tinged by new ideals, different interests must be united and considered in the planning and design of school grounds. Based on the importance of nature for children's health and development, this study examines two school grounds in Malmö from three perspectives: the school grounds design and shape, the use and preferences of the students on the school grounds, and the planner´s priorities and proceedings in planning school ground environments. The purpose is, through an understanding of how these three perspectives can unite, to increase knowledge on how school grounds can be planned more socially and ecologically sustainable in the transformative city. This is investigated with a mixed method through site observations, surveys and interviews. The empirical evidence shows a relatively passive relation to the school ground among the students, regardless of the school grounds size and amount of greenery, and generally they prioritize social interaction and mobile phone use during breaks. The interpretation of the empirical material, based on the theory, indicates that it is the quality of the greenery that affects the student’s interest in using the environment. Through the interviews, it emerged that the design of a green framework that offers different spatialities can contribute to a more equal, inclusive and sustainable school ground. The ideal environment of the school ground, which can be considered one that is characterized by natural environments, does not necessarily reflect the student's ideal of it. The students' preferences can however be accommodated within the sustainable framework through continuous design. sustainable urban development densification urban green spaces school grounds affordance attention restoration theory (ART) mental bandwidth temporary urban development co-creative planning continuous design hållbar stadsutveckling förtätning urbana grönytor skolgårdar affordance attention restoration theory (ART) mental bandbredd temporär stadsutveckling medskapande planering aktiv gestaltning Political Science Statsvetenskap Social Sciences Interdisciplinary Architecture Arkitektur Humanities and the Arts Humaniora och konst
55	市場風險值管理之應用分析以某金融控股公司為例 / The analysis of Market Risk VaR management ：the case of financial holding company 周士偉, Chou, Jacky Unknown Date (has links) 2008年次貸風暴橫掃全球金融市場，Basel II制度歷經多年的實施，卻無法有效防阻金融風暴的發生。觀察2008已採用內部模型法之主要國際金融機構之年報，亦發現採用蒙地卡羅模擬法之代表銀行『德意志銀行』於該年度竟發生了35次穿透，市場風險管理到底出了什麼問題？這是被極度關心的現象，產官學界也對此現象提出了許多議題。2012年的現在，次貸的風暴尚未遠去，新的歐債危機也正在蔓延，若金融風暴再次來臨，市場風險管理是否能克服次貸風暴後所凸顯的缺失，市場風險管理的價值除被動管理外，是否還可以進階到主動預警，以作為經營決策的重要參考資訊？這些都是國內金融機構需積極面對的急迫的市場風險管理議題。個案金控的市場風險管理機制致力於解決次貸以來所凸顯的市場風險管理議題、提升市場風險衡量的精準度、擴大市場風險管理之應用範圍，並將市場風險管理的價值由被動管理角色進階到主動預警角色，以期作為經營決策的重要參考。經過多年的淬煉，其發展理念與經驗應具相當參考價值，故本論文以個案金融控股公司(以下簡稱個案金控)之實務經驗進行個案研究，除分析個案金控市場風險管理機制的基礎架構外，也將研究重心放在個案金控如何在此基礎架構下，開發多種進階市場風險量化管理功能。本論文除研究個案金控如何完善市場風險值量化機制外，也對各量化功能的實施結果進行分析，以期研究成果可更客觀的作為其他金融控股公司未來發展進階市場風險衡量機制之參考。市場風險風險值經濟價值信託基金操作風險風險因子一般風險值壓力風險值條件風險值增額風險值邊際風險值變異數-共變異數法歷史模擬法蒙地卡羅模擬法隱含波動度厚尾順景氣循環標準法內部模型法市場流動性風險外生性市場流動性風險內生性市場流動性風險流動性調整後風險值壓力測試回溯測試 Market Risk Value at Risk Economic Value Active Management VaR Tracking Error Risk Factor Common VaR Stressed VaR Conditional VaR Incremental VaR Marginal VaR Variance-Covariance Approach Historical Simulation Approach Monte Carlo Simulation Approach Fat Tail Time-Varying Volatility pro-cyclical Standardized Approach Internal Models Approach Implied Volatility Generalized Error Distribution Bernoulli trial test Likelihood ratio test Unconditional Coverage Test Conditional Coverage Test Backward Looking Model Forward Looking Model Forecasting VaR Pearson Correlation Cholesky decomposition Kendall Correlation Copula method Future Volatility Disconnection Market Liquidity Risk Exogenous Market Liquidity Risk Endogenous Market Liquidity Risk Liquidity-adjusted VaR Stress Test Backtesting Net Interest Income Re-pricing Model Maturity Model Duration Model
