Mjölkkyl till espressomaskin : Impressive cooler
The project was made in cooperation with Coffee Queen AB, Arvika. The task was to develop and design a new cooler for the milk to Jura Impressa X9, an espresso machine. The good assistance with staff at Coffee Queen and engineers in China and at KPA in Karlstad led to a solution to the problem. It was a long road to get there, many different concepts was developed. When the day came to decide which concept to work with, the choice stood between two different technical solutions.
Förändringar i västra Yoldiahavets vattenmiljö under trettioett år : En studie av fossil från ostracoder, mollusker och foraminiferer från Myssjaren, östra Mellansverige
I denna studie undersöks hur vattenmiljön förändrades i ett område av västra Yoldiahavet, idag sjön Myssjaren i östra Mellansverige. Syftet med undersökningen har varit att återskapa hur vattnets salthalt förändrades i området genom att studera förekomsten av fossil från saltvattenkrävande bentisk kalkskalsfauna i lera från perioden.Fossil hittades från sju år, 10 395-10 388 lervarvsår BP, av den 31 år långa period, 10 410-10 379 lervarvsår BP, som har undersökts. Utifrån fossilförekomsten kunde det konstateras att vattnet var bräckt under dessa sju år. Eftersom att fossil inte hittades från tidigare och senare perioder Därför är det möjligt att vattnet var bräckt både före och efter denna period.Det som begränsade de undersökta arternas utbredning i området var halten suspenderat sediment i vattnet. Det var en konsekvens av att mycket sediment transporterades till området i och med att området befann sig mellan två större utlopp av glacialt smältvatten.Därför har denna studie, förutom att konstatera att vattnet var bräckt under den undersökta perioden, även visat en succession av arter i Yoldiahavet.I studien identifieras också en 4 år lång kallperiod som varade mellan 10 393-10 389 lervarvsår BP.
Vem bryr sig? : Ett kommunikativt perspektiv på fusionen mellan Växjö Universitet och Högskolan i Kalmar
This essay takes the three models from Allison and Zelikow book Essence of decision and applies them on the Swedish defense system. After the cold war the Swedish defense system had to undergo changes to be a more modern defense and be able to defend Sweden against threats. To also be able to cooperate with other countries in peacekeeping operations the Swedish defense had to be reorganized. The solution was to change direction from a defense system that was organized for invasion to instead be a movable defense ready for any challenge in Sweden or abroad. This reorganization will be analyzed according to the three different models..
Utvärdering av laddningskoncept för lastbilsbatterier
When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.
Det etniska säkerhetsdilemmat-en idealtypsanalys över etniska konflikter
In the world after the Cold War, internal and ethnic conflicts have been predominant. Ethnic conflicts have their own theories on why they erupt and what can be done to solve them. This essay seeks to analyze how the Ethnic Security Dilemma can explain the causes, and possible solutions, of today´s armed ethnic conflicts.By making an ideal types typology over different types of ethnic conflicts, and then analyzing the Ethnic Security Dilemma´s impact on each conflict type.

Optimering av OTEC-system
Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.
En Djupdykning i Kommunikationsstrategi : om konsten att locka folk till svenska dykvatten
Purpose/Aim: To create a communication strategy for PADI Nordic with the intention of getting Swedish divers, who have been certified abroad, to Swedish dive centers.Material/Method: The study is based on a number of personal interviews conducted with a) divers who are active in Sweden, b) divers who are not active in Sweden and c) representatives from PADI and PADI affiliated dive centers.Main results: The main reason that people who have been certified abroad do not dive in Sweden is that they regard it as being too complicated, too cold, too expensive and with nothing interesting to see. These might partly be misconceptions that can be corrected through a communication strategic effort. The best way to change this perception is by two different forms of communication. One will go from PADI Nordic straight to the divers through an email. This will have the purpose of getting their attention, making diving sound interesting and raise their awareness in preparation for the other part of the process.
Värvningsförbud av anställda och konkurrensbegränsande samarbeten
This thesis focuses on employers? use of non-?solicitation of employees in commercial contracts within the union?s internal market and how this can result in restrictive practices in violation of European law. Using legal method, legal economic considerations, and guidance from modern American legal development in antitrust law, this thesis is aiming to investigate how this kind of anticompetitive cooperation in the European labor market should be assessed. The result seems to be that despite a distinct and pronounced restrictive approach to the application of EU competition rules in the labor market, there are strong incentives and not any legal impediment to apply Article 101 TFEU on no cold call agreements between employers. .
Den villkorliga självkänslans relation till self-efficacy
A self-esteem that is contingent on affirmation from others leaves the individual psychologically vulnerable. Ccontingent self-esteem has been shown to be either relationship or competence based. The aim of the current study was to examine the relationship between relationship based self-esteem, competence based self-esteem, the under dimensions of those, and self-efficacy. Questionnaires were handed out to 69 university students. The results indicated that competence based self-esteem predicted a significantly low self-efficacy.
Energieffektivitet och kvalitet på inomhusluft i radon förorenade bostadshus
To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.
Skuggvävens effekt på fryslagrade täckrotsplantor av tall (Pinus sylvestris) i upptiningsstadiet :
This project was an assignment by Sveaskog and Svenska Skogsplantor. The purpose was to study the effect of protective fabric on the thawing stage of frozen pine seedlings. The function of the protective fabric is that it should protect the seedlings against strong sunlight and create an even temperature inside the boxes containing the seedlings. The result has shown that there was no statistically significant difference when the protective fabric was used or when it was not used, although this was probably due to the weather conditions. The study was carried out under cold and cloudy weather conditions and probably would have given other results if there had been more sunny days with a higher ambient temperature.
Galoppträning och körning med två travare
The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.
Luft/luftvärmepump : - Med möjlighet till återvinning
Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems."Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has installed electrical radiators and an exhaust ventilation system that makes the energy demand high due to the large ventilation flows. The building was built as the price of electricity was still low and would reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs.
Sverige och Nato : En studie om de svenska relationerna till Nato efter det kalla krigets slut
The purpose of this essay is to examine the Swedish relations to Nato and by doing so see on what terms the cooperation is executed and why. However, Sweden is not a member of Nato and is thereby not seen as an ally of the organization but even so Sweden has a close cooperation with Nato. The theories used in this essay is The Rational Actor Model and The Organizational Behaviour Model by Graham Allison and Philip Zelikow. To this a number of additional theorises are used as to complement these two main theories. The aim with these theories is to see which one gives the most satisfying explanation of the Swedish strategy to cooperate with Nato and still not be a member of the alliance or if all theorises are needed.
