In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.

AbstractThe purpose of this study is to find out how pupils give expression of a water cycle model and if the model causes any misunderstanding. Two problems constitute the starting point for this investigation. The first question is: how do the pupils explain the water cycle with the help of the jar model (can of glass). The other question is: can the children see any similarities between the can of glass and our earth. Qualitative semi structured interviews with seven pupils in the ages of 8-9 have been used to show the pupils? own thoughts and how they express them.

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

En stillasittande livsstil utgör idag ett mycket stort folkhälsoproblem och fysisk aktivitet är något som förespråkas i samhället. Motivation är en förutsättning för att en person skall kunna förändra sin livsstil. Distriktssköterskan skall befrämja den fysiska, psykiska och sociala hälsan och kan göra det genom att hjälpa människor att finna sin egen motivation. Distriktssköterskan möter patienter med skilda hälsoproblem och olika grad av motivation. För att kunna möta människors olika behov är det av betydelse att ha kunskap och förståelse för vad motivation innebär och hur det uttrycks.

The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.

Penningtvätt är ett ämne som under de senaste åren fått mycket uppmärksamhet. Nya lagar och regleringar med målsättningen att förebygga och bekämpa penningtvätt har införts. För att uppskatta problemets storlek har ett flertal estimat beräknats med hjälp av olika metoder. I denna uppsats har vi valt att fokusera på de metoder som används för att beräkna estimat, då det finns tecken som tyder på att estimaten som beräknas sällan utsätts för kritik.Syftet med uppsatsen har varit att undersöka och jämföra tre av de idag vanligaste metoderna för att beräkna penningtvättens storlek. De vanligaste modellerna är Walkermodellen, Zdanowicz metoder för handelsbaserad penningtvätt och en två-sektor modell vilka har utgjort fokus i denna studie.

Background: In 1998 it was stated that Swedish municipalities would report the pension liabilities according to the mixed model where the pension liabilities before 1998 was moved from the balance sheet. The mixed model has been criticized by economists for not showing the total pension liabilities. To remove some of the liabilities in the municipalities balance sheets means that the solvency improves. Some municipalities have decided to go against the municipal accounting law and recognize all of the pension liability as a liability according to the full funding model. When two accounting models are being used the comparison of the municipalities' financial statements is much harder.Purpose: The main purpose of this study was to study the reason why some municipalities apply full funding model rather than the mixed model.

Bakgrund: Nästan var tionde patient i den svenska somatiska sjukhusvården drabbas av envårdskada (1). Ungefär 50% av dessa sker i samband med kirurgiskt ingrepp (2). När patientergenomgår ett kirurgiskt ingrepp förväntar de sig att få en säker vård. Men vad innebäregentligen begreppet patientsäkerhet?Syfte: Syftet med arbetet var att göra en analys av begreppet patientsäkerhet ur ettvårdvetenskapligt perspektiv och i samband med kirurgiskt ingrepp.Metod: I arbetet har en begreppsanalys gjorts av begreppet, enligt Walker och Avants modell.

The purpose of our essay is to examine if variation exists in the way that auditors try their independence, this so called analysis-model. We will suggest some factors that influence the way auditors practise the analysis-model. The institutional theory predicts no differencies since the normative pressure could be expected to be severe. But we found that among other things people?s qualifications, personalities and audit firm?s size and age influence the way auditors try their independence.

Body awareness is a term that refers to a person´s perception and knowledge about his or her body. It includes proportion, size, weight, contour and image of ones body. The Ben- Tovim Walker Body Attitudes Questionnaire (BAQ) contains 44 questions concerning the different aspects of body awareness: Feeling fat, Body disparagement, Strength and fitness, Salience of weight, Attractiveness and Lower body fatness. The purpose of this study was to investigate body awareness among men in military recruit training. BAQ was distributed to fifty recruits for military service in Boden.

Bakgrund: Hur vet vi som sjuksköterskor vad som menas när det talas om palliativ? Världen utvecklas och så gör även begreppen i den. Genom att studera ord får forskaren reda på den egentliga betydelsen och den allmänna definitionen. Syfte: Att klargöra och definiera begreppet palliativ. Metod: Begreppsanalysmodell av Walker och Avant (1995).

A new material model, for the FE-program ADINA, has been verified against twoexperiments. One unreinforced concrete beam and one reinforced concrete beam.The model, DF-concrete, has the possibility to estimate true concrete. However theresults indicate that in order to be sure that the estimations are true, there ought tobe data from the true concrete to verify against.Two FE-models have simulated the behavior of a ring-shaped part of the nuclearcontainment vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment vessel. Thesimulations of the nuclear containment vessel show cracking in the concrete after10-11 bars of over pressurization.

Problems:How would a decision model that takes into account more aspects and dimensions than just the financial aspect look for smaller service compa-nies? What aspects are important to consider in such a decision model?Purpose:The purpose of this master thesis is to develop a decision model based on previous research, to improve decision making in smaller service com-panies ? by considering perspectives that traditional investment calcula-tions ignore.Method:The study was qualitative and was based on both primary and secondary data. As data collection method for the development of the model we used literature search on previous research. The study?s primary data consisted of responses from five smaller service companies.

Through geopolitical theory this thesis explores how conflicts within states can be read and understood according to an analytical model determining one or several possible causes for the conflict.  The model is created by the author and reflects geopolitical theory by giving three possible explanations to an intrastate conflict: culture, economy or territorial construction. The aim of the thesis is testing this model on two selectively chosen case studies ? i.e. two intrastate conflicts ? namely: the upcoming referendum in Scotland and the terror attack at Tiananmen Square in China.

The work with this report has been focused on developing a methodology model for control at purchase. The methodology model covers parts classification, dispatching systems, batch shaping and more. The aim with the methodology model is that it will be used as an aid for a cost effective material planning to increase the value for customer.The work covers also a description of the present situation and the purchase process at Company X. Six parts have been applied, two from each class (A, B and C), in the methodology/model. The parts that have been applied are included in the flow between Company X and their supplier Company Y.Data have been collected trough literature studies, interviews and the company?s business system.
