In molecules, electronic state transitions can occur via quantum coupling of the states. If the coupling is due to the kinetic energy of the molecular nuclei, then electronic transitions are best represented in the adiabatic frame. If the coupling is instead facilitated through the potential energy of the nuclei, then electronic transitions are better represented in the diabatic frame. In our study, we modeled these latter transitions, called ``nonadiabatic transitions.'' For one nuclear degree of freedom, we modeled the de-excitation of a diatomic molecule. For two nuclear degrees of freedom, we modeled the de-excitation of an ethane-like molecule undergoing cis-trans isomerization. For both cases, we studied the dependence of the de-excitation on the nuclear configuration and potential energy of the molecule. We constructed a numerical model to solve the time-dependent Schr\"{o}dinger Equation for two coupled wave functions. Our algorithm takes full advantage of the sparseness of the numerical system, leading to a final set of equations that is solved recursively using nothing more than the Tridiagonal Algorithm. We observed that the most effective de-excitation occurred when the molecule transitioned from a stable equilibrium configuration to an unstable equilibrium configuration. This same mechanism is known to drive fast electronic transitions in the adiabatic frame. We concluded that while the adiabatic and diabatic frames are strongly opposed physically, the mathematical mechanism driving electronic transitions in the two frames is in some sense the same.

In this thesis, I explore how performance storytellers create intense focus on imaginal realities through language—a phenomenon sometimes called “transport” or “realm-shift.” To this end, recordings of performances by two professional storytellers were transcribed and examined through the lens of frame theory and discourse analysis. Examination of these transcripts shows that storytellers employ clusters of linguistic involvement strategies around frame transitions, facilitating realm-shift. Additionally, it shows that throughout a telling, tellers shape discourse around frame shifts that draw attention to significant elements, particularly those that establish a story’s relevance to the occasion of its telling and those that contribute to meaningful story interpretation. This research highlights the ways that meaningful interpretation of a story depends on successful navigation of frames, revealing that the power of a storytelling event depends largely on the connections between realms of discourse.

KL-träelement används som stommaterial i allt fler flerbostadshusprojekt i Sverige, då det fortfarande är en relativt ny metod är det intressant att undersöka den närmare. Vid val av stomme är byggtiden ofta en viktig faktor och därför ligger montagetiden till grund för jämförelsen i studien. Denna rapports syfte är att ge mer information inför valet genom att jämföra en KL-trästomme med en platsgjuten betongstomme utförd med plattbärlag och skalväggar med hänsyn till tidsåtgång av montage. En litteraturundersökning har genomförts för att analysera vilka faktorer som påverkar tidsåtgången vid resning av de två stomalternativen. Planeringsverktyget Powerproject har använts för att ta fram en tidsplanering för vardera stomme. Tidsplaneringarna har sedan jämförts för att se vilket stomalternativ som ger minst tidsåtgång. För att stommarna ska bli så jämförbara som möjligt har gemensamma egenskapskrav ställts på bärighet, brandmotstånd och ljudisolering samt U-värde. När stommen uppfyller dessa krav, betongen torkats till 90 % relativ fuktighet och efterföljande aktiviteter kan påbörjas bedöms stomarbetet klart. Simuleringarna av tidplanerna har gjorts för kvarteret Norrstjärnan i Örebro som har använts som referensobjekt. Tiderna i rapporten är baserade på underlag tillhandahållet av NCC. Utifrån tidsplaneringarna för referensobjektet konstateras att den totala tidsåtgången för en KL-trästomme är 125 arbetsdagar och 169 arbetsdagar för en betongstomme. Det är en skillnad på 44 arbetsdagar vilket ger en procentuell skillnad på ca 35 %. / CLT-elements are used as frame material in an increasing number of multi-dwelling buildings projects in Sweden, as it is still a relatively new method, it is interesting to investigate it more closely. In the choice of frame, construction time is often an important factor and therefore the assembly time is the basis for the comparison in the study. The purpose of this report is to provide more information prior to the choice by comparing a CLT-element frame with a cast concrete frame made with lattice girder system and half shell precast walls with regard to the time required for assembly. A literature survey has been carried out to analyze which factors influence the time spent on raising the two frame options. The planning tool Powerproject has been used to develop a time schedule for each frame. The time schedules have then been compared to see which framework alternative gives the least amount of production time. In order for the frames to be as comparable as possible, common property requirements have been set for bearing capacity, fire resistance, sound insulation and U-value. When the framework meets these requirements, the concrete is dried to 90 % relative humidity and subsequent activities can be started, the work with the frame is considered finished. The simulations of the timetables have been made for the project Norrstjärnan in Örebro, which has been used as a reference object. The times in the report are based on data provided by NCC. Based on the time schedules for the reference object, it is stated that the total time spent on a CLT-element frame is 125 working days and 169 working days for a concrete frame. This is a difference of 44 working days, which gives a percentage difference of about 35 %.

The development of steam turbines is continuously moving forward and the aim is oftento develop configurations with higher power output. Siemens Industrial Turbomachinery AB is currently in the beginning of a development project which replaces a single turbine with two interconnected turbines with higher pressure and temperature of the steam than before. To ensure reliable quality and hold down costs is it an advantage to do most of the assembly before delivery to site.This thesis work at Linköping University has been written in collaboration with Siemens Industrial Turbomachinery AB, Finspång. The objective of this work is to investigate the possibility to mount two turbines and a gearbox on a turbine frame. Theframe will be used both for transportation and during operation.The thesis considerate analyses of the turbine layout and critical parameters that may affect a turbine frame. In addition was a frame concept developed and evaluated with respect to solid mechanics and alignment of the shaft arrangement.Our conclusion is that there are good possibilities to install the equipment on a frame and achieve demands due to solid mechanics and alignment of the shaft arrangement.We recommend Siemens Industrial Turbomachinery AB to carry on with the project and do further investigations of the natural frequency of the frame concept, compare financial advantages and disadvantages together with possibilities for transportation.

The purpose of this thesis is to investigate the inelastic action in the reinforced concrete frame-wall structures analytically and with that analysis to follow the plastic formation of the structure. For this purpose, six mid-rise reinforced concrete buildings with frame-wall are modeled and analyzed to understand the effect of the height and base shear force ratio of the wall on the nonlinear interaction between reinforced concrete wall and frame members under static lateral loads and ground motion excitations. The parametric analysis is conducted by assuming planar response of the buildings under loadings. The buildings are generated considering the limit design concept suggested by Turkish Earthquake Code 2007 and Turkish Standards TS500, and the frame-wall members are modeled by using spread plasticity elements and fiber discretization of sections. In the analysis stage, each element section is divided into confined and unconfined regions for detailed modeling of the building by using OpenSEES nonlinear finite element program. Two dimensional analyses are conducted under static and dynamic loadings. For static pushover analyses, three different lateral load cases (Triangular, Uniform and First-Mode Lateral Load Patterns) are considered. For dynamic analyses, eight different ground motions are used. These ground motions are scaled to the corresponding design response spectrum suggested by Turkish Earthquake Code 2007 by using RSPMATCH program. Using the result of the complex and simplified analyses, inter-story drift ratios, plastic rotations and internal force distributions of the buildings are investigated.

While previous research into understandings of climate change has usually examined general public perceptions and mainstream media representations, this thesis offers an audience-specific departure point by analysing climate change frames and frame formation in Swedish agriculture. The empirical material consists of Swedish farm magazines’ reporting on climate change, as well as eight focus group discussions among Swedish farmers on the topic of climate change and climate change information. The analysis demonstrates that while Swedish farm magazines frame climate change in terms of conflict, scientific uncertainty, and economic burden, farmers in the focus groups tended to concentrate on whether climate change was a natural or human-induced phenomenon, and viewed climate change communication as an issue of credibility. It was found that farm magazines use metaphorical representations of war and games to form the overall frames of climate change. In contrast, the farmers’  frames of natural versus human-induced climate change were formed primarily using experience-based and non-experience-based arguments, both supported with analogies, distinctions, keywords, metaphors, and prototypical examples. Furthermore, discussions of what constitutes credible climate information centred on conflict-versus consensus-oriented frames of climate change communication along with different views of the extent to which knowledge of climate change is and should be practically or analytically based. This analysis of climate change communication in the Swedish agricultural sector proposes that the sense-making processes of climate change are complex, involving associative thinking and experience-based knowledge that form interpretations of climate change and climate change information. / Den här avhandlingen studerar uppfattningar om klimatförändringar och bidrar med sin målgruppsorienterade utgångspunkt till tidigare forskning kring hur klimatförändringar kan förstås och uppfattas. Avhandlingen studerar klimatkommunikation inom den svenska lantbrukssektorn genom analyser av 10 års klimatrapportering i tidningarna ATL samt Land Lantbruk, samt åtta fokusgruppsdiskussioner med svenska lantbrukare. Analysen visar att medan svensk lantbruksmedia ramade in klimatförändringar som en fråga om konflikter, vetenskaplig osäkerhet och ekonomisk börda, rörde lantbrukarnas diskussioner om klimatförändringar (i) dess orsaker; naturliga eller antropogena, (ii) olika faktorer som påverkar huruvida klimatinformation anses trovärdig. Därtill visar avhandlingen att lantbrukstidningar använde krigs- och spelmetaforer för att gestalta klimatförändringar medan lantbrukarna formade klimatinramningar genom analogier, distinktioner, nyckelord, metaforer och prototypiska exempel. Tillsammans med lantbrukarnas upplevda erfarenheter bildade dessa kommunikativa verktyg olika gestaltningar av klimatförändringar. Lantbrukarna visade på olika uppfattningar kring trovärdighet och klimatinformation. Vanligen efterfrågades ett informationslandskap karaktäriserat av en mångfald av perspektiv. Återkommande i materialet var också uppfattningen att kunskap om klimatförändringar borde vara praktiskt baserad snarare än teoretisk hållen för att öka i trovärdighet. Denna avhandling kring klimatkommunikation inom den svenska lantbrukssektorn pekar på komplexiteten i tolkningsprocesser och visar att associativt tänkande och erfarenhetsbaserad kunskap tillsammans utgör grunden för hur klimatförändringar och klimatinformation uppfattas.

Governments and policy-makers are currently dealing with some key issues as energy security in countries dependent on oil imports; global economic development, including increased food production; and controlling global climate change and greenhouse gas emissions. The perception that biofuel could solve these challenges simultaneously has led to the implementation of policy and regulatory mechanisms on the mandatory use of biofuels, resulting in a sharp increase in biofuel production and consumption. Serious concerns about large-scale ethanol production have been raised regarding loss of biodiversity and competition for land between food and ethanol production. It is also suggested that sugarcane-based ethanol increases GHG emissions due to indirect land use change. Furthermore, sugarcane harvesting has been criticised for causing air pollution and bad working conditions for cutters. These criticisms have mostly been denied by Brazilian actors. This thesis seeks to clarify these divergent views and conflicts concerning Brazilian ethanol. It was carried out within a KTH research programme that uses frames in the analysis of conflicts emerging from the development and implementation of new technologies. Frame analysis can help improve understanding of such conflicts, which derive from differences in values, world views and beliefs and can be difficult to resolve. Frame analysis seeks to identify the particular factors determining the actions taken by different stakeholders, giving equal treatment to all actors. The results showed that the international views expressed in the media captured the attention of the public and policy-makers, and led them to frame ethanol as a destructive for nature fuel. The analysis identified that the ethanol as a threat to food security frame combined with the ethanol as a destructive for nature frame led the public and policy-makers to frame ethanol as a brown fuel. However, Brazilian actors frame ethanol differently: as a green and safe fuel. These differences have raised the conflicts that are analysed in this thesis. Furthermore, the analysis identified that the changes in the harvesting system, from manual to mechanised –besides decreasing air pollution- will cost the job of hundreds of thousands of cane cutters. Values and beliefs orientating such changes are analysed in the thesis. / QC 20110912

As constructive process, the LSF shows a progress compared to the traditional system is characterized by being an industrial building, rationalized with high productivity and require one skilled labor. The ergonomic point of view, such a system offers significant improvements in employees' working conditions and despite these improvements are significant, we can still identify ergonomic problems related to the activities of workers. In this context, this work aims, through ergonomic work analysis - AET, to survey the critical activities performed during the construction process and a diagnosis of the situations encountered on site. This research is exploratory to be keen to discover and observe phenomena, trying to describe them, classify them and interpret them and their driving was used as a research method, the case study. To capture the data, makes use of ergonomic analysis of manual work - EWA (Ergonomic Workplace Analysis), METs (The standard metabolic equivalent) and OCRA (Occupational repetitive actions) in which the following items were considered: Load-lifting, accident risk, attention, general physical activity, working postures and movements and repetitiveness of the work. Among the main findings stand out: the high risk of this accident carrying out the work due to organizational process of the company, moderate caloric expenditure in the execution of activities and high IE OCRA present in fixing activities (screwing) the structures and the sealing elements. / Sistemas construtivos pré-fabricados em Light Steel Frame - LSF são amplamente utilizados em países desenvolvidos como Inglaterra, Japão e EUA. Como processo construtivo, o LSF apresenta uma evolução quando comparado com o sistema tradicional, caracteriza-se por ser uma construção industrializada, racionalizada, com elevada produtividade e por demandar uma mão de obra capacitada. Do ponto de vista ergonômico, esse sistema apresenta melhoras significativas nas condições de trabalho dos trabalhadores e, apesar dessas melhoras serem significativas, ainda podemos identificar problemas ergonômicos relacionados às atividades dos trabalhadores. Dentro desse contexto, esse trabalho busca, por meio da análise ergonômica do trabalho – AET, realizar um levantamento das atividades críticas desenvolvidas durante o processo construtivo e realizar um diagnóstico das situações encontradas em obras. Essa pesquisa tem caráter exploratório por estar interessada em descobrir e observar fenômenos, procurando descrevê-los, classificá-los e interpretá-los e na sua condução utilizou-se como método de pesquisa o estudo de caso. Para a captura dos dados, fez-se uso de três instrumentos ergonômicos: manual de análise ergonômica do local de trabalho – EWA (Ergonomic Workplace Analysis), MET's (The Standard Metabolic Equivalent) e do OCRA (Occupational repetitive actions). Foram considerados os seguintes itens para avaliação: elevação de carga, riscos de acidente, atenção, atividade física geral, posturas de trabalho e movimentos e repetitividade do trabalho. Dentre os principais resultados obtidos, destacam-se: o elevado risco de acidente presente na execução da obra, devido ao processo organizacional da empresa, gasto calórico moderado na execução das atividades e elevado IE OCRA presente nas atividades de fixação (parafusamento) das estruturas e dos elementos de vedação.
