A ocorrência desta violência pode implicar, em alguns casos, no afastamento da vítima da convivência familiar e comunitária, através da aplicação de medidas jurídicas de proteção a vítima, passando esta a viver em abrigo institucional. Mas, paradoxalmente, o que era para ser excepcional e transitório, tem-se configurado como a modalidade mais utilizada pela sociedade brasileira, e o tempo de permanência nos abrigos tende a ser longo. Assim, esta pesquisa tem como objetivo geral analisar o processo de institucionalização e desinstitucionalização através da perspectiva das adolescentes vítimas de abuso sexual. Buscou-se conhecer o “mundo” social, o cotidiano e os vínculos afetivos e sociais das adolescentes ingressas, e as representações sociais que as egressas (re)constroem no momento da saída do abrigo após (longos) anos de institucionalização, sinalizando para os desafios encontrados na vida de egressa. Para dar conta dessa dimensão privilegiamos uma metodologia de pesquisa qualitativa e de caráter exploratório. A Instituição estudada foi a ONG Lar Flor de Lis, Salvador/BA, que ampara cerca de 120 crianças e adolescente, do gênero masculino e feminino. A maioria dos abrigados é composta de afrodescendentes, possui baixa escolaridade, são oriundos de bairros periféricos de Salvador, Região Metropolitana e municípios do interior do Estado da Bahia. O recorte empírico privilegiou cinco adolescentes do gênero feminino, vítimas de abuso sexual. Verificou-se que as representações sociais sobre o abrigo são experienciadas de forma ambígua, sendo este entendido como um espaço de apoio, proteção, quanto de aprisionamento. Em relação a sua vivência na instituição, observou-se que o abrigamento tende a ser visto pelas adolescentes como uma dupla punição, sentem-se injustiçadas pelo afastamento da convivência familiar e comunitária, e pela impunidade do agressor. Uma questão apontada nos casos de abuso sexual verificada nessa pesquisa é que há uma tendência para uma idealização cristalizada de um tipo imaginário de família feliz, normal, dissimulando dessa forma, a realidade socioafetiva familiar vivenciada por essas, e a negação das relações de violência e “proteção social”.The shelter of children and adolescents is one of the forms of institutional care foreseen in the Child and Adolescent Statute (ECA), Law 8.069/90 (updated by Law 12,010 of 2009) as a measure of exceptional and temporary protection in cases of threat or violation of rights of children and adolescents, including sexual abuse cases against children and adolescents. The occurrence of this violence can lead, in some cases, to the removal of the victim from his/her family and community, through the application of legal measures to protect the victim that then begins to live in an institutional shelter. But, paradoxically, the measure of protection that is supposed to be exceptional and temporary, has been configured as the modality of protection used most often by Brazilian society, and the length of stay in the shelters tends to be long. Thus, this research aims to analyze the process of institutionalization and deinstitutionalization through the perspective of adolescents victims of sexual abuse. We sought to understand the social "world", the everyday life and the social and emotional bonds of intern teenagers, and the social representations that those who leave (re) build on leaving the shelter after (long) years of institutionalization, signaling to challenges encountered in the after-shelter life. To understand this dimension we favor a qualitative exploratory research methodology. The institution studied was the NGO Lar Flor de Lis, Salvador / BA, which shelters about 120 children and adolescents, male and female. Most sheltered children and adolescents are Afro-Brazilian, have low education, and are from the outskirts of Salvador metropolitan area and municipalities of the state of Bahia. The empirical cut favored five teenage female victims of sexual abuse. It was found that social representations about the shelter are experienced ambiguously, being perceived as a place of support, protection, but also of imprisonment. Regarding their experience at the institution, it was observed that the shelter tends to be seen by teenagers as a double punishment, they feel wronged by the separation from the family and community, and by the impunity of the perpetrator. It can be noticed in the sexual abuse cases analyzed in this research that there is a tendency toward idealizing a happy, normal, family, thus disguising the reality of the socio-affective family experienced by these, and the denial of the relations of violence and "social protection.

Transient vehicle thermal management simulations have the potential to be an important tool to ensure long component lifetimes in heavy-duty vehicles, as well as save development costs by reducing development time. Time-resolved computational fluid dynamics simulations of complete vehicles are however typically very computationally expensive, and approximation methods must be employed to keep computational costs and turn-around times at a reasonable level. In this thesis, two transient methods are used to simulate two important time-dependent scenarios for complete vehicles; hot shutdowns and long dynamic drive cycles. An approach using a time scaling between fluid solver and thermal solver is evaluated for a short drive cycle and heat soak. A quasi-transient method, utilizing limited steady-state computational fluid dynamics data repeatedly, is used for a long drive cycle. The simulation results are validated and compared with measurements from a climatic wind tunnel. The results indicate that the time-scaling approach is appropriate when boundary conditions are not changing rapidly. Heat-soak simulations show reasonable agreement between three cases with different thermal scale factors. The quasi-transient simulations suggest that complete vehicle simulations for durations of more than one hour are feasible. The quasi-transient results partly agree with measurements, although more component temperature measurements are required to fully validate the method.

Mauritius is an isolated island with ambitious targets for renewable energy generation and plans to invest in more solar power. The aim of this study is to assess how the implementation of photovoltaic technologies might affect the frequency stability in Mauritius and thus assess whether solar power can help the country obtain their targets for green energy generation. The research question is answered by conducting a literature study and simulating relevant scenarios in Matlab and Simulink. By simulating the frequency response for a production disturbance with different values for system inertia and PV capacity, the inertia requirements for frequency stability is assessed. Mauritius appears to have a high potential for increasing solar power generation. Based on the simulations, their electrical grid seems to be able to maintain frequency stability with PV capacity corresponding to the generation targets for 2020, 2025 and 2030, even for low amounts of system inertia. However, the significance of these results are called into question because of the varying quality of input data. With more accurate, specific data, the applicability of the results can be improved. Nevertheless, the study can be used as a guideline on how to use the given model to evaluate frequency stability in isolated power systems in island states. Ways to further this study is to evaluate other stability challenges related to PV production such as the reactive power in the system, voltage stability and rotor angle stability. / Mauritius är en isolerad ö som har sett en stor ekonomisk växt de sista åren. För att möta en ökande efterfrågan på el på ett hållbart sätt har Mauritius satt ambitiösa mål för förnybar energiproduktion som bland annat innebär betydande investeringar i solkraft. Målet med denna studie är att utvärdera hur implementeringen av utökad solcellskapacitet skulle kunna påverka frekvensstabiliteten i nätet på Mauritius och således fastställa ifall solenergin kan bidra till deras mål om ökad grön energiproduktion, utan att öka risken för strömavbrott. Frågeställningen besvaras genom att först utföra en litteraturstudie och sedan använda en matematisk modell, utvecklad av Danilo Obradovic från KTH, för att simulera relevanta scenarier i Matlab och Simulink. Simuleringarna visar frekvenssvaret vid produktionsbortfall som relateras till den mängd svängmassa som behövs för att säkerställa frekvensstabilitet vid olika mängder solceller. Litteraturstudien visar att Mauritius har god tillgång på solinstrålning och solceller verkar vara en lämplig teknologi för att utnyttja denna energin. Enligt de simuleringar som genomförts verkar Mauritius kunna bibehålla frekvensensstabilitet om den installerade solcellskapaciteten ökas till de planerade nivåerna i 2020, 2025 och 2030, även för låga värden på systemets svängmassa. Slutsatserna bör dock analyseras kritiskt då indatan som används för simuleringarna är av varierande kvalitet. Med bättre och mer specifik indata kan den föreslagna metodiken och modellen användas för att dra mer relevanta slutsatser för Mauritius. Metodiken som använts i denna studie kan därav ses på som en riktlinje för hur frekvensstabiliteten i isolerade elnät kan undersökas. Vidare kan studien utökas genom att utvärdera sociala och ekonomiska aspekter och även andra stabilitetsfrågor relaterade till en ökad mängd solceller, så som den reaktiva effekten i systemet, spänningsstabilitet och rotorvinkelstabilitet.

<p>Although traditional hazard analysis techniques, such as failure modes and effect analysis (FMEA), and fault tree analysis (FTA) have been used for a long time, they are not well-suited to handling modern systems with complex software, human-machine interactions, and decision-making procedures. This is mainly because traditional hazard analysis techniques rely on a direct cause-effect chain and have no unified guidance to lead the hazard analysis. The Systems Theoretic Accident Model and Process (STAMP) is based on systems theory to try to find out as much as possible about the factors involved in a hazard, and with providing clear guidance as to the control structure leading to the hazard.</p> <p>The Darlington Nuclear Power Generating Station was the first nuclear plant in the world in which the safety shutdown systems are computer controlled. Although FTA and FMEA have already been applied to these shutdown systems, Ontario power generation felt that it is still useful to try recent advances to evaluate whether they can improve on the previous hazard analysis.</p> <p>This thesis introduces the two most common traditional techniques of hazard analysis, FTA and FMEA, as well as two systemic techniques, STPA (which is a hazard analysis method associated with STAMP), and the Functional Resonance Accident Model (FRAM). The thesis also explains why we chose STPA to apply to the Darlington Shutdown System case, and provides an example of the application as well as an evaluation of its use compared with FMEA and FTA.</p> / Master of Applied Science (MASc)
