This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

Graphic design is an integrated part of the public spaces we move through in our daily lives. This thesis explores the emotional aspects of graphic design, with a focus on environmental graphics for the public space. The goal is to find ways in which the emotional aspects of a design solution can be varied without compromising the practical aspects, i.e. affect the conveyance of information. This goal is pursued through an analysis of historical and contemporary literature as well as by design practise.

 A villas price depends on several important factors. By statistical data, a mathematical multiple regression model was modeled. The model has important explanatory variables such as living space, renovation year and standard points has been taken into consideration, in order to assess their impact on the final price for private homes.By using a statistical program,Minitab 16, the final model was selected with eight explanatory variables. The regression for this model explains up to 67.3 % of the variation on the final price.The results showed percentage wise that the standard points had the greatest impact on the price, there after renovation year and then living space..

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

The purpose of this study is to examine the Swedish national student organizations attitudes towards school food and the school food debate between 1957-1982. The previous research on the subject maps the historical background and development of the school meal, but lacks a contemporary student perspective from the chosen time period, not least on a deeper and more political level. The theoretical starting points in the study concern organizations and their influence on public authorities as well as student influence. These theoretical frameworks are used to describe the conditions for the currently active national student organizations; Elevf?rbundet and SECO, in the political arena.

Purpose: The purpose of this thesis is to examine the ERK model's relevance, validity and potential need of development to better reflect how it looks today (2013). Method: The study is conducted through three surveys; the first two were face interviews with companies that sponsor Swedish soccer teams and the third study was conducted with a questionnaire to supporters outside a soccer stadium. Results: A model that would better reflect the reality of today (2013) could contain company pride, chairman?s whim, exposure, relationships and associations..

To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.

Den förväntan en gäst har på en måltidsupplevelse är central i arbetet med att skapa extraordinära måltidssituationer. I studien har de faktorer som skapar förväntan på en måltidsupplevelse sökts fram och dess påverkan på skapandet av förväntan studerats.Uppsatsens syftet var att undersöka hur rummet kan påverka gästens förväntningar och upplevelser i en måltidssituation.Studien grundar sig på fakta hämtat ur granskade, publicerade vetenskapliga artiklar som sökts fram med hjälp av centrala, det vill säga relevanta och viktiga, sökord ur databasen FSTA. Resultatet visade att den förväntan en gäst har på en måltidsupplevelse skapas och baseras på ett flertal olika faktorer. Dessa faktorer är bland annat det omgivande rummet med dess design, dukning och inredning, den yttre miljön, den marknadsföring och information som getts, personal och bemötande samt den sociala interaktionen i samband med måltiden. Egen empiri och förförståelse utifrån liknande, tidigare upplevelser bidrar också till att skapa en förväntan på den upplevelse som skall komma att konsumeras.

This thesis deals with the information-seeking behaviour of occupational therapists. Focus was on three different aspects of information-seeking behaviour. The purpose was to investigate how occupational therapists conceive of work-related information needs, their choice and use of formal and informal information sources and their use of the hospital library. Twelve interviews with occupational therapists were conducted at a rehabilitation clinic in a hospital. The theoretical frame consists of a general model of the information-seeking of professionals by Leckie, Pettigrew and Sylvain.

The building industry are currently going through a huge alteration. The introduction of BIM (Building Information Modeling). Which also implements a lot of new ways of solving problems that building modeling can cause. This report is written for Uppsala University in cooperation with Temagruppen in Uppsala. However, it contains a comparison between two different systems that checks building models.

This thesis deals with the compatibility between analysis software Revit Structure2012 and Robot Structural Analysis 2012. The purpose is to become more aware ofinformation management models to be compatible across different softwareapplications. The structural model is made to be optimal for the compatibility of othersoftware Aim is also to gain an understanding of the transferring methods that exist,and which method is most convenient to use and to examine whether the methodswork in practice. Objective of this project is to make the modeling processtime-efficient for constructors. Models do not need to be structured in severaloccasions in different software; it only needs an optimal model that transfers properlybetween software.The method used in the thesis consist cases where the transferring process isexamined.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

Syftet med detta arbete är att undersöka vilken uppfattning pedagoger i förskola och skola har om sambandet mellan mat och koncentration. Anser de att mat har en betydelse för barns förmåga att delta i de verksamheter de befinner sig i? För att barn och vuxna skall orka vara delaktiga i sociala sammanhang och kunna vara koncentrerade krävs en näringsriktig kost. Vi har därför sökt att få fram vad som betraktas vara en näringsriktig måltid för barn. Genom enkätundersökning, intervju, observation samt litteraturstudier har vi försökt att få fram svar på dessa frågor.

If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.

The purpose of this paper is to analyze the ongoing changes in German family policy. It explores the issue of whether the German welfare state, in this policy field, can still be regarded as a conservative welfare model or rather approaches a more liberal or social democratic model. A qualitative method is used to analyze the material, especially from the German government, including press releases, other public documents and also articles from the political weekly magazines Der Spiegel and Die Zeit. The changes analyzed are the new parental benefit, the expansion of child care, the concept of whole-day schools and the system of joint taxation. The point of departure is Gösta Esping-Andersen?s categorization of three types of welfare states: the social democratic, the conservative and the liberal.
