Yrkesrelevant Gymnasiearbete på El- och Energiprogrammet

The purpose of this development project is to create a model for working with a high school project in Electrical and Energy Program. It should be conducted in a form like companies do according to the goals from The Swedish National Agency for Education. In order to fully perform this we use the concept of Young Entrepreneurship. The model is created according to the new conditions from The National Electrical Safety Board. There is now an exception saying that a student during education is released from the demand of employment that is the normal procedure where you are under supervision from a certified electrician. During the project there has been theoretical and practical examinations in order to clear out the advantages and disadvantages using this model, but also to examine whether it is useful in the future and to what extent it can be used. The result indicates that the model is useful and fulfills the goals from The Swedish National Agency for Education but that the model has its limitations and difficulties.

Beräkning av energianvändning i svenska småhus

An energy calculation model for Swedish houses   that is fast, flexible and user-friendly has been developed within the   framework of this thesis.  The model   also provides a set of actions which may be investigated in the model based   on savings and payback period. Energy use in a house depends on the technical   conditions, such as building envelope and heating systems, which outdoor   climate the house is exposed to and who lives in the house. Energy use for a   house can be divided into heating, hot water and household electricity. There   are several methods to calculate the energy use of a house. This report   summarizes the methods that may be suitable for a fast and user-friendly   calculation model.

Marknadens riskpremie ex-ante på Stockholmsbörsen

Resultaten visar på att abnormal earnings model är en mertillförlitlig modell i förhållande till dividend growth model. Dettafrämst då abnormal earnings model grundar sig på mer tillgängliginformation samt att tillväxträntan i dividend growth model harkonstaterats vara orealistiskt hög. Analytikers prognoser tenderaratt vara optimistiska i början av undersökningsperioden 2000-2002. Perioden 2003-2007 präglas mer av pessimistiskavinstprognoser. Marknadens riskpremie fluktuerar mindre underperioden 2005-2007, vilket kan förklaras utav införandet av IFRSår 2005..

Värdeförändring på butiksfastigheter och makroekonomiska variabler - en ekonometrisk studie av samvariation

The purpose of this Bachelor thesis in Economics at Lund University is to try to establish the correlation between the value change of retail real estate buildings in Sweden and macro economic variables. The principal method is the multiple regression model and it is used to estimate the basic model. The basic model is enhanced by estimating some 30 models and the result is two good models. The difference between the basic model and the two better models are small but important. In the lagged basic model, the same variables are used as in the basic model but with different time lags.

Den svenska modellen och dess framtid

This study reflects on the swedish model and the models future. The swedish modelmeans that legisilation acts with the collective agreements . The wage issue is notregulated by law instead it is managed by the social partners in the form of collectiveagreements. In 2008, a report was presented by the Commission on a joint regulation ofthe minimum wage for all EU countries. The issue has become increasinglycontroversial and was especially disccused for the election of candidates to theEuropean Parlament last spring.

En studie om införandet av expected loss model : - En mer tillförlitlig och relevant metod för nedskrivning av finansiella tillgångar?

Accounting has been critized for being one of the leading factors in the latest financial crisis. One of the primary problem areas was identified as delayed recogonition of losses on financial instruments. Consequently, a new impairment model is being developed and is to be namned expected loss model. The difference from the present model, incurred loss model, is that it takes losses into consideration on an much earlier level. Even though the model may be theoretically feasible, in practice it may implicate a number of issues.

Modellering av hydrauliskt aktuatorsystem

This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.

A Long Day?s Journey into Night ? examining the Swedish model, present and future

In this essay we strive to examine how the social work in Sweden will be affected if the Swedish welfare model goes through fundamental changes. The study illuminates the close connection between the Swedish collective bargaining model and the Swedish welfare system. The questions we present in this essay, and hopefully answer satisfactory, are: is the Swedish welfare model subject to thorough changes? How will such a change alter the social work in Sweden?, is the Swedish collective bargaining model in a state of modification? Would a modification in the collective bargaining model have effects on the Swedish welfare model?We have used a qualitative method in collecting empirical material. We interviewed three representatives, who worked for Confederation of Swedish Enterprise, IF Metall and The Swedish Municipal Workers respectively.

Jämförelse mellan MultiScat och konventionell beräkning av intensiteter till koncentrationer vid analys med röntgenflourescensspektrometri

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.

Barns tolkning av en modell för vattnets kretslopp : -förståelse och tillämpning

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.

Transferfunktionsmodeller modellering och prognoser av Sjötransportindex

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.

Parametriserad modell av motorprototyp med Solidworks

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.

Kommunernas dolda pensionsskuld

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.

Analysmodellen - en variation i tillämpningen?

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.

Icke-linjära modelleringsteknikerav förspänd betongkonstruktion : Reaktorinneslutningen på Forsmark 3

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.
