There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.

Bankruptcy is a problem for the society in form of high costs for including suppliers, customers, employees, investors, banks, insurance companies etc. The purpose of this study is to confirm or dismiss a bankruptcy prediction model that has been developed in a previous Swedish study, in order to predict bankruptcy with help of specific key figures. The model has only been tested in a larger perspective where the population consisted of all small firms in Sweden, in this study the model´s reliability is tested by that it instead been applied to a minor perspective, where the population only includes Stockholm. With a quantitative approach of 12 different key figures from a total of 60 Swedish smaller registered companies in Stockholm between the years 2005-2007, has been studied. The companies are divided into two groups, companies with good financial health and companies that have ended up in bankruptcy.The results shows that the model is applicable in a smaller population, but some of the key figures do not generate essential or any type of information about bankruptcy, but the majority of the key figures in the model did.

A frequently asked question in real estate marketing is at what time of the year it is optimal to invest or sell. The aim of the project was to answer this question and to generate a prediction model over real estate located in the centre of Stockholm that takes seasons into account. With acquired sales statistics in Stockholm between 2010 and 2013 it was possible to perform a linear least square regression, also known as Ordinary Least Square (OLS), with describing qualities and season of sale as parameters. Statistical problems such as Multicollinearity and Heteroskedasticity have been taken into account when deriving the model. The result was a highly accurate prediction model indicating the profitability of investing in real estate during the summer and selling during the autumn..

Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110). The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.

This essay is included as a sub-study of a survey about child poverty, which the Department of Sociology at Uppsala University, the Ombudsman for Children and Gillbergska Stiftelsen (the Gillberg?s foundation) has been commissioned by Uppsala Town to implement. The intent of this essay is to investigate how three pre-school managers in the municipal preschool in Uppsala describe child poverty, how they see the preschool?s social responsibility and how they manage child poverty in their practical operation. The essay is a qualitative study and informants' responses has been analyzed and related to symbolic interactionism, the thesis theoretical basis.

Fastighetsmäklaryrket och fastighetsmäklartjänsten debatteras ofta, både i media och privat, en anledning till detta kan vara att bostadsaffären är en av de största affärer som görs under ens livstid. I denna uppsats vill författarna belysa den rådande uppfattningen om fastighetsmäklare och fastighetsmäklaryrket i Uppsala samt att söka påvisa var utrymme finns för en förbättring av kundens upplevda tjänstekvalitet. En undersökning av vilka förväntningar som människor har på fastighetsmäklare, vilken tjänstekvalitet som har upplevts, samt vad fastighetsmäklare tror om människors förväntningar, har genomförts.För att svara på frågorna ställda i problemformuleringen använde sig författarna av modellen SERVQUAL-P, med en komplettering från modellen RESERV, som påvisar gap mellan upplevd och förväntad tjänstekvalitet samt mellan kundernas förväntningar på tjänsten och tjänsteutövarens tro om vad som förväntas. För att illustrera olika förväntningsgap används en gapmodell som är bunden till SERVQUAL-P.Utöver insamling av sekundärdata, insamlades också primärdata via en enkätundersökning riktad till potentiella kunder och de som tidigare hade varit i kontakt med fastighetsmäklare, samt en motsvarande enkätundersökning riktad till fastighetsmäklare.Undersökningen resulterade i små SERVQUAL-P-gap som tyder på att förväntningarna på fastighetsmäklartjänsten till stor grad motsvaras av upplevelserna och att inga större kriser finns att se för fastighetsmäklartjänsten i Uppsala. Rekommendationer som ges bör därför mer ses som en vägledning för framtiden än som problem som måste åtgärdas.

Det som motiverar en människa behöver inte motivera en annan, det finns många olika faktorer som påverkar en människas motivation. I denna uppsats undersöktes vad som motiverade teknologer och naturvetare vid Uppsala universitet att engagera sig ideellt inom Uppsala teknolog- och naturvetarkår. Teorin som har använts är inre och yttre motivation, samt fyra behovsteorier; Maslows behovspyramid, Herzbergs tvåfaktorsteori, McClellands behovsteori och Alderfers ERG-teori. Utifrån denna teori togs 13 stycken nyckelord fram till en analysmodell, vilken sedan låg till grund för påståendena i enkäten. Metoden som användes i undersökningen var kvantitativ och resultatet visade att inre motivation hade mycket större påverkan än yttre motivation för ideellt engagemang.

Internal working models of attachment are claimed to be unconscious structures operating outside the conscious awareness. Existing measures of attachment are almost exclusively explicit, either self-reports or interviews and it is questionable whether these instruments are able to tap into unconscious attachment attitudes. The main purpose of the present study is to develop Implicit Association Test (IAT) tools for assessing adult attachment and to examine their construct validity. Two sets of implicit attachment measures, based on the two-dimensional attachment model (Bartholomew & Horowitz, 1991), were developed. Convergent validity was assessed by examining (1) the relationship between implicit model of self and implicit self-esteem and (2) the relationship between the implicit model of other and implicit sociability.

This thesis is a case study of the search function on the University of Uppsala?s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical.

Vi hade en skissuppgift i bo?rjan av kandidatprojektet, da?r vi skulle fundera o?ver va?r passion till arkitekturen. Min passion kan vara minnet av en byggnad, ett rum, da?r jag ka?nt ett sug i magen. Jag inspireras av film, teater, foto och konst.

In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.

In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.

Målet med undersökningen är att utreda hur sju definierade stadskvaliteter ser ut i två bostadsområden i Uppsala och att undersöka om dessa kvaliteter på ett enkelt sätt kan mätas. Vidare diskuteras dess inverkan och framtida betydelse för de två områdena, och en generell diskussion om hur de sju stadskvaliteterna kan behandlas i stadsbyggnadssammanhang förs. I en rapport gjord i Stockholm visar resultaten att sju stadskvaliteter tydligare korrelerar med betalningsviljan för bostadsrätter än andra stadskvaliteter. Baserat på dessa sju attraktiva stadskvaliteter för boende undersöktes kvaliteternas förekomst genom platsbesök och analys av stadsdelarna Gottsunda och Kungsängen. Resultaten visar att Kungsängens centrala läge i Uppsala gör att tillgången till de sju stadskvaliteterna är högre än i Gottsunda.

This report brings up the question - ?Is BIM profitable when planning a single-family home??.The methodology for finding the answer to this question is firstly to state the definitions of BIMand the company that is projecting by using the BIM-model. The answer is then obtained byanalyses of the factors of profitability with respect to: time, opportunity of revision, problemvisualization, preference adjustments and energy. A BIM-model has been made simultaneously asthe writing has proceeded to get a perception of how a BIM-model really matters for the analysis.The analysis shows that the answer for the question depends on further factors. The factors thatare mostly discussed are the company?s intentions and the complexity of the house.
