Utveckling av lastmodell för Uppsala fjärrvärmenät
The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.
Framtagning och analys av en arbetsmodell för kartläggning av användarbehov
This study began with a mission statement from the firm Tobii Technology AB to identify customer needs in the relatively new and rapidly growing market for eye tracking analysis. After consuling external experts, the authors however found that the availability of previous academic published market studies of new and fast growing markets was poor. Therefore a decision was made to execute the task and at the same time create a methadology for future studies in this area. The identification of customer needs, which formed the basis of the insights and analysis, led to frequent discussions between the authors and the firm's supervisors. This resulted in a project plan and a decision that an iterative model would be used, were earlier decisions would be questioned and refined throughout the project.
Kunskapsteori och kunskapsorganisation: En diskursanalys
This Masters thesis concerns epistemology in Knowledge Organization KO, as a field of study in Library and Information Science LIS. Using a theoretical model by Birger Hjørland and foucauldian discourse analysis as springboards, this study analyses three epistemological discourses in the practice of KO. The aim of the study is to show how these discourses are constituted and demarcated in relation to KO, as well as to examine how they fit into Hjørlands model. A brief historical outline of some epistemological trends in LIS is sketched, as well as examples of how different epistemological schools influence different parts of KO, e.g. information retrieval, indexing- and classification theory.
Metoder för prediktion av kardiovaskulär sjukdom med njurfunktionen
This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which measure of prediction one prioritizes..
ITS under byggtid - utvärdering med dynameq : Fallstudie: Intunnling av E4/E20 Tomteboda - Haga södra
Essingeleden in Stockholm is the most heavily congested road segment in Scandinavia and it is ofgreat importance for as well traffic within the city as for transit traffic. The capacity of Essingeledenand Norra Länken is not enough to accommodate all traffic. At times it is not moving at all, whichresults in long queues and an augmented risk of accidents. Consequently measures for increasing thecapacity on E4/E20, which will reduce congestion and the risk of accidents, are implemented byTrafikverket. In fall 2012 one lane of three at Pampas will be closed and so will the exit fromEssingeleden to Norra Stationsgatan, called Parkeringsbron.
Målsättning, prognostisering och resursfördelning i en budgetstyrd bank respektive budgetlös bank: En fallstudie av två svenska banker på kontorsnivå
Speaking of budget and budgeting is almost as adding fuel to the fire. The subject evokes a lot of emotions, both positive and negative. Some might consider budgets as a bureaucratic process that won?t lead to any good. Others might find budgets as extremely helpful and necessary in a company?s planning process.
Transporttidsmodellering vid provpumpning i heterogen jord : spårämnesförsök i en isälvsavlagring
When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. Nevertheless, many aquifers are strongly heterogeneous which may lead to differences between estimates and actual travel times. As a part of the process to develop improved methods for delineating protection zones for groundwater supply wells, a tracer experiment was performed in a glaciofluvial esker formation in Järlåsa. On the basis of the experiment, a numerical flow model was created for the test site.The purpose of this master?s thesis was to apply the flow model to an aquifer where the hydraulic conductivity shows great variability and should be described by a stochastic distribution.
Några aspekter på filmens tid : Ögonblicket och nuet i filmen och fotografiet
Abstract Cinematic time is the most complex of all: it is composed of public time (clock), personal time (experienced) and in addition, it can run backwards, be contingent, stored and (re)created. The present study examines some aspects of cinematic time, with special reference to the instant, the moment and the present. The strictly defined instant or moment does not exist. It is a passage between the past and the future and it is impossible to record on film or a photograph. One example is the moment of death, which is an abstraction with zero duration.
Kol-14 datering : En litteraturstudie över hur kol-14 isotopen används för datering, samt utveckling och tillämpning av djup-åldersmodeller inom naturgeografin.
This literature study concerned the use and function of the radioactive isotope carbon-14, as a dating method of organic material, within the scientific field of physical geography. In this report it is presented the need of atmospheric calibration curves and the development of these as a necessity to translate carbon-14 years to calibrated calendar years. A number of common age-depth models that is used to give an approximation of an accumulation sequence and its related dates over the actual time period in different natural archives is presented and discussed. Different problems that commonly occur when age-depth models are utilized as for instance reservoir effects, contaminations or other age deviations are addressed and analyzed. The software CLAM in presented and discussed and was also used to produce age-depth models.
Ett företags internationaliseringsprocess : - i ett land kulturellt skilt från dess hemmamarknad
AbstractPurpose:The purpose of the study is to describe the internationalization process of one firm when in a country culturally diverse from the firm?s original market.Methodology/approach:The study is a single case study which examines one firm?s internationalization process when entering the Chinese market. The approach has been an empiric interaction between empirical and theoretical data.Findings:The theory of the Uppsala model was applied to the case-company to test the model?s completeness. The authors found weaknesses and added three more aspects to the model.
Effekter av kön, ålder och region på sjukpenningen i Sverige - en variansanalys
According to TCO (The Swedish Confederation for Professional Employees) the worst threat to the Swedish welfare is that so many people because of bad health and unemployment are not a part of the labour force. If Sweden could make the number of people with health and unemployment problems half the size as today, the GDP would increase with more than five percent. In real money this means 110 billion Swedish kronor a year. According to SCB (Statistics Sweden) the difference between women?s and men?s absence owing to illness should be investigated more closely in order to get at better understanding of the problem.
Den aggregativa demokratin : Hur Jürgen Habermas, John Dryzek och Stephen Elstub använder termen liberal demokrati
?Liberal Democracy? is a common term in political theory, and it is used as if it had a commonly accepted referent, with both normative and descriptive content. This is certainly the case in democratic theory, where it on the one hand seems to refer to a normative democratic model; on the other hand it is used descriptively, to refer to real-life democracies. The deliberative democratic sub-field is not an exception; on the contrary, the term is frequently used albeit rarely defined; yet the concept it refers to is supposedly developed enough to allow detailed propositions about its citizens?s political behaviour.This essay is an attempt to analyze how Liberal Democracy is used by three deliberative democrats (Jürgen Habermas, John Dryzek and Stephen Elstub), in order to understand the democratic model (or models), whether normative or descriptive, they refer to.
Gestaltningsförslag till ny förskola på Zakrisdal
Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.
Svarstiden vid klinisk bedömning av högre språkliga förmågor hos vuxna
The aim of the present study was to investigate response time variations in tasks for assessment of high level language functions and how response time is related to education, age and gender. Response time is defined as the time to complete a task after it has been presented. 103 subjects, aged 20 to 80 years, were tested with the Assessment of Subtle Language Disorders, Sentence analysis and Morphological completion. The subtest Comprehension of ambiguous sentences showed the longest response time and Morphological completion the shortest. Correlations were found between increasing age and longer response time for Comprehension of metaphors and between education and response time for several subtests.
