Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören

The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.

Kommunala kulturmiljöprogram : strategiska planeringsunderlag för landskapsanalys, kulturhistorisk värdering och utveckling av kulturmiljöer

In 1999 the Swedish Parliament decided about 15 environmental goals aimed to be achieved in time for the next generation. For example physical social planning must be based on programs and strategies how cultural-historical values has been attended, so called programs of cultural heritage. By law the Swedish municipalities are responsible for reaching these goals by creating program of cultural heritage. But only a few of the municipalities have these programs, meaning that many municipalities need to create programs of cultural heritage in the next five years.The aim of this report is to present a model of analysis on programs of cultural heritage in municipalities for preservation and development of cultural environments. By testing the model on the municipalities of Osby and Tomelilla methods on how to create a new program of cultural heritage or how to complete existing documents are formulated.One of the conclusions is that one document, program of cultural heritage, functions as landscape analysis, model of cultural valuation and strategy of developing cultural values.

Beräkningsmodell för massbalanser för Slottshagens reningsverk

In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..

Emotionell intelligens : En studie av den dskursiva produktionen av begreppet emotionell intelligens i ett organisationssammanhang

Emotional Intelligence (EI) is a highly used concept in contemporary organizations, especially in the recruitment process or education of employees and managers. The aim of this study was to examine the discursive production of the concept emotional intelligence and how it, linked to an organizational context, is expressed in web-based articles and course homepages. In total 11 texts related to emotional intelligence and organizational contexts were used as the object of study. A three-stage model was used as a method for analysis. The model included a content analysis, argument analysis and a deconstruction analysis in order to expose what was said about emotional intelligence and how it was said.

Prognosmodell för svenska läns bruttoregionalprodukt (BRP) : En komparativ analys av bayesian model averaging, best subset selection och en longitudinell modell.

Föreliggande uppsats har som främsta syfte att skapa en prognosmodell för bruttoregionalprodukten (BRP) för Sveriges 21 län. Behovet av en prognosmodell motiveras av att Statistiska centralbyrån (SCB) i dagsläget redovisar de definitiva siffrorna av BRP med två års fördröjning. Det kan därmed finnas ett intresse hos regionala beslutsfattare att få en uppfattning om hur BRP utvecklats under de två senaste åren. Metoden som används är bayesian model averaging (BMA), vilken kommer att utvärderas samt jämföras med två andra metoder: En multipel linjär modell som skattas med minsta kvadratmetoden där variabelselektion utförs med best subset selection (BSS). Den andra metoden är en tidsseriemodell och kallas här för en longitudinell modell (LM).

Överlevnadsanalys i tjänsteverksamhet : Tidspåverkan i överklagandeprocessen på Migrationsverket

Migrationsverket är en myndighet som prövar ansökningar från personer som vill söka skydd, ha medborgarskap, studera eller vill jobba i Sverige. Då det på senare tid varit en stor ökning i dessa ansökningar har tiden för vilket ett beslut tar ökat. Varje typ av ansökning (exempelvis medborgarskap) är en process som består av flera steg. Hur beslutet går igenom dessa steg kallas för flöde. Migrationsverket vill därför öka sin flödeseffektivitet.

Utvecklingsarbete med inriktning på gruppsamverkan

The idea to create authentic learning situations where students are highly integrated made me want to try to develop a new method in the course Restaurant and Catering B MAKU 1208 (another field practicing cuisine). In my quest to do just the practical part as rewarding, stimulating and efficient as possible for the student, I planned for a training model with   focus on group interaction.The implementation of the model for learning was to strengthen students confidence both in themselves and in each other, stimulated to greater cooperation and it has also provided an incentive to the student's own development but not least, a growing self-confidence for many students. Several have also had an increased sense of knowing something, to have something to contribute and that their labour input actually was needed. While highlighting that further education to seek knowledge strengthens the individual's skills and consolidates and increases deeper knowledge in the professional field.In conclusion, training should be done in both individual and group basis for optimal learning process..

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.

Processorienterad arkivredovisning : Ny arkivredovisningsmodell tilla?mpad i fem svenska la?rosa?ten

The investigation analyzed the implementation and application of the Swedish National Archives' new Process-Oriented Archives Description Model to activities of the hierarchical, function-oriented and decentralized university organizations.The basic reason why a new archive description has evolved is because documents are becoming more and more digital. It requires a new interpretation of how evidence is secured for their reliability and authenticity, and a new way of looking at provenance, for the purpose of describing and searching electronic documents. The new archive description model's logical structure is based on business processes.The relationship between the new archive description and a function-oriented organization's activities can be seen from the different outlooks of processes between archive activities and activities of the organization. It is also reflected in the modification that all universities have made ??of the new archive description model to be more flexible and pragmatic to fit a function-oriented organization.The relationship between provenance and process-oriented archive description is mainly the link between documents and business processes that produce them.

Den oretuscherade sanningen - En oretuscherad modells påverkan på konsumenters CSR-uppfattning, attityder och köpintention

Within the subject of retouching there is an ongoing debate about whether fashion retailers should retouch their ads or not. There has been a large amount of criticism to the communication of stereotyped beauty ideals that is used by companies in their marketing. The stereotyped ideals also contribute to negative psychological effects among people. As a response to the criticism, or as a way to differentiate one-self from competitors, retailers are starting to use unretouched models in their advertising. How this affects the consumer's perception of CSR along with the attitudes and behaviors is still unknown.

Skogs påverkan på vindkraftsproduktion - en fallstudie av vindkraftverk vid Andersfält.

The purpose of this master thesis is to investigate how nearby forests affect the energy production in wind turbines. To reach the purpose a case study is performed on three wind turbines sited on a field in a north-south line at Andersfält in the municipality of Halmstad, Sweden. Approximately 100 meters south of the southern wind turbine a forest is situated. The case study is divided into three sub studies where the difference in energy production, the affect of the forest and a wind meteorology model, WAsP, is studied. The result show that the forest have a significant influence and that the WAsP-model gives an incorrect result of the energy production in wind turbines sited near a forest..

Det osynliga entreprenörskapet : - en intervjustudie av företagare med utländsk bakgrund

The invisible entrepreneurship is a study of owners of businesses with foreign heritage. It describes the unexplored relationship between ethnicity and class within this group of entrepreneurs.The result of the study is a model which I have found to be suitable to use when depicting the relationship between the ethnic profile and class. The model indicates that the importance of ethnicity decreases as both the owner of, and the business reach a more prominent class. The method of collecting data has been interviews with owners of businesses and Grounded theory has been used to analyse this data. Theories on ethnicity, owners of businesses with foreign heritage, and class in relation to ethnicity have been discussed on the basis of social constructivism.
