Klimatanpassning och lantbruket i Värmland : Klimatförändringarnas upplevda effekter på lantbruket och olika aktörers åsikter om klimatanpassning

Climate change is a global and slow process that affects humans all over the world. Climate adaption within agriculture is important to reduce the risks that agricultures are exposed to because of climate change.  Through climate adaption you can improve the positive effects and take advantage of them optimally. How the climate change affects agricultures varies depending on regions and societies. The purposes of the study are to examine how different actors experience the impacts of climate change on the agriculture in Värmland.

Bitcoins adaption : En undersökning av faktorer som påverkar Svenska företagares val att implementera Bitcoin i sin verksamhet.

Många länder går mot ett samhälle där kontanter används till en mindre grad vilket har lett till en ökning av elektroniska betalningsmetoder. Utöver kortbetalningsmetoder har andra mer hög teknologiska betalningsmetoder vuxit fram. Bland dem är Bitcoin ett nytt system som vuxit sig relativt stor under de senaste åren. Bitcoin är både kritiserat och hyllat i olika medier. Utifrån de två väletablerade teorierna; Diffusion av innovation och Teknologi acceptans modellen avser studien att identifiera betydande faktorer i Svenska företags adaption av Bitcoin.

Pedagogers adaption av surfplattor : En studie av implementeringen av iPad i en F-5 skola

The tablet is a new IT-tool which have started to get introduced into school, but research is still missing and especially in the pre-school environment. The purpose with this study is to investigate teachers uptake, how they use the tablet in everyday pedagogy work as well as the organizational conditions that that facilitate and hinders. Through my observations and interviews in a Swedish K-5 school I have found that the teachers find tablets more appealing to use in comparison to computers. These findings are partly supported by Davis et al.?s (1989) TAM-theory who considers there to be three types of aspects that affect the way individuals adapt to technology.

Marknadsföring av ungdomsverksamhet på folkbibliotek

The purpose of this bachelor thesis is to examine the methods public libraries can use in order to market youth services. It is also a chance to evaluate an untested marketing model adapted to public libraries. Young people are one of the most difficult groups to attract to the library and thus librarians need adequate methods to deal with this problem. We have interviewed librarians, carried out observations and examined documents in accordance to the triangulation method. Before one can begin marketing the libraries one ought to know of how marketing is done and the principles behind it, therefore we have given a simple explanation of marketing and marketing theory.

Fattar du vad de säger? : En begriplighetsanalytisk jämförelse mellan Ekot och P3 Nyheter

In this study we compare Ekot with P3 Nyheter with a comprehension analytical perspective. The more traditional radio news program Ekot differs from the younger P3 Nyheter in a lot of aspects. One of them is that P3 Nyheter?s primary target group is young people between the ages of 20 to 34. Because of this, P3 Nyheter aim to make their news as adjusted to their young audience as possible.

Logikbaserade dokumentåtervinningsmodeller

The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

eWOM-kommunikation på Facebook & Prisjakt : En studie av skillnader i konsumenters uppfattning om eWOM

Purpose ? The purpose of this study is to identify and describe how consumer perceptions regarding information quality, sender credibility and effect of eWOM-communication differ between Facebook and Prisjakt.Approach ? Based on previous research an analytical model was designed. The parts in the model were the aspects of the problem which the present study aimed to examine. An experimental design was applied in which ten students at Örebro University were exposed to a scenario where they took part of eWOM-communication concerning a specific product on Facebook and Prisjakt and then had to answer questions in an interview. The analytical model formed the base of the interview guide used in the interview and the specific product was chosen with help from a focus group.Implication ? The study illustrates that consumers may perceive the quality higher on Prisjakt while the sender credibility can be perceived higher on Facebook.

Modellering, identifiering och reglering av skannern i ett laserbatymetrisystem

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

Från bok till film - The Hunger Games : En karaktärs- och miljöanalys

Syftet med denna uppsats är att jämföra boken The Hunger Games (2008) av Suzanne Collins med filmen The Hunger Games (2012) regisserad av Gary Ross och försöka ta reda på vilken sorts adaption som är gjord. Jag arbetar med boken och filmen The Hunger Games var för sig för att eventuella skillnader ska framträda tydligare vad gäller karaktärer och miljöbeskrivning. När jag gått in på djupet och jämfört boken The Hunger Games med filmen märker jag vad som är förändrat. Till exempel saknas vissa karaktärer och scener i boken i filmversionen, medan andra scener har lagts till i filmen. Samtidigt är det förståeligt att en del måste göras om och tas bort för att en bok på flera hundra sidor ska kunna visas i en film på cirka två timmar.

Summary Title: How to make decisions on software based servicedevelopment in the mobile handset industry.?The Rapid Model for Holistic Application Evaluation Authors: Per-Inge AnderssonPatrik Dreveborn Tutors: Björn Regnell, Department of Computer Science,Lund UniversityRobert Wenglén, School of Economics and Management,Lund University Problem formulation: Academically the questions of finding out what constitutes a sound decision base and finding out how to handle the issue of a holistic approach must be addressed in order to make a well balanced and relevant decision model. The core question is which decision criteria to include and which drivers are important in estimating the status of the criteria? Practically to provide Sony Ericsson with a formalized evaluation process for decisions on software development that is transparent, objective and challengeable. Purpose: Academically to contribute to the field of decision making research by elaborating on how to make a holistic, rapid and rational decision model.

Modellering av indunstning på Södra Cell Mönsterås

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

Modellering av en panna med rörlig rost :  

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

Adaptiv katalysatormodell för reglering

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.
