This thesis work resulted in a template for how the thermal spray process can be controlled through robot programs. The robots today and their programs need to be replaced, therefore a new structure which can be matched with the new robot systems is needed. The work is limited to only concern structured programming on the new robots on Thermal Spray Centre (TC) with the programming language Rapid. The basic data for the program was retrieved from interviews with concerned personnel at TC, from studies on process parameters for thermal spray and from existing specifications at Volvo Aero Corporation (VAC). The thesis work briefly describes the process thermal spray and the four methods used at VAC.
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.
Klimatförändringar, ett problem för vem? : En institutionell policystudie om könets betydelse i svensk klimatpolitik
The UN has a goal to gender-mainstream all politics, but its politics in climate change is not gender-sensitive. The Swedish government has the same goal concerning gender mainstreaming, but does the Swedish politics of climate change reach this goal? The aim of this paper is to examine the relations between the Swedish politics of gender and climate change. In addition, the aim is also to investigate how gender is constructed in the climate politics. To reach these aims, an institutional, policy and gender analysis is used.
Den försvinnande staten Tuvalu : En fallstudie om klimatflyktingars rättigheter och staters ansvar
This thesis aimed to, with the help of a case study, investigate and discuss state responsibility towards climate refugees. The state of Tuvalu was selected because of their vulnerability as a low-lying island state. This was fulfilled by on-site study how the state Tuvalu acted to climate threats, determine if the future migrants from Tuvalu can be counted as climate refugees and find out if they are by that definition included by the UN Refugee Convention. The result indicated that the state of Tuvalu is adapting to climate threats, that in the future the population can be seen as climate refugees, if they are forced from their homes due to climate change, and that they, despite that definition, can not be included by the UN Refugee Convention. The study also indicates a need for greater international protection of climate refugees by, for example, an expansion of the UN Refugee Convention so that these vulnerable people do not fall into oblivion due to a question of definition..

Solenergi på Nya Karolinska Solna
In today?s society climate change has grown to one of the largest global issues. To reduce emissions of greenhouse gases, large changes of the energy system are required. An increasingly popular solution is investments in local production of renewable energy resources like wind, solar or geothermal power. The following report examines the possibility for implementing a solar power plant on the new hospital Nya Karolinska Solna. Two different technologies for extraction of solar energy has been studied, solar thermal collectors to meet the need of heating and solar cells to satisfy the need for electricity linked to operating the hospital building.
Metoder för lastprioritering i fjärrvärmecentraler
A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.
Metodik för identifiering av T-stycke med risk för termisk utmattning
Thermal fatigue is a serious problem in todays power plants. A large amount of damages around the world circles around that subject. The damage can come from the mechanism of two flows mixing with different temperatures in a T-junction. It is a fundamental prerequisite that these T-junctions are frequently tested for damages. An amount of criterias steers the rate of testings.
Inverkan av Kiselhalten på Värmeutvidgningskoefficienten hos Aluminiumlegeringar
The purpose of this report is to document the experiments carried out, methods used and results gained during research into how the silicon content of an aluminium alloy affects the coefficient of thermal expansion (CTE).The goal of this paper is to better understand and to find a relation between silicon content and the coefficient of thermal expansion.Experiments were carried out using carefully prepared samples of Al Si alloys (0, 7, 10 and 20% Si content). Using these alloys, the CTE could be measured using a dilatometer.Comparative analysis carried out could map the effects of silicon content on the coefficient of thermal expansion and an equation was created. Using simple graphs and the rule of mixture method, the authors were able to build a simple tool for calculating the CTE of specific aluminum silicon alloys..
Hur förhåller sig EU till en (o)hållbar utveckling? En studie av EU:s klimatpolitiska samhällsstyrning inom jordbruks- och klimatpolitiken
This bachelor thesis, written as a part of the European Studies at Gothenburg University, is concerned with the European Unions? (EU) climate political governance in their both climate- and agricultural policy, and in particularly the question whether it is sustainable. This thesis intends to problematize if it is possible for the EU to continue to pursue its current agricultural policies, while at the sametime maintain its role as a sustainable actor on the global arena. The framework of theEUs? climate policy governance disciplines this analysis.
EN ANNAN RETORIK? Nationalistiska partiers anv?ndning av nationalistisk milj?- och klimatpolitik
Climate change is a phenomenon that know no boundaries. While focus on environment and
climate change has become highly prioritized, nationalism has spread across Europe.
Nationalism is by many considered to refuse action to combat climate change although some
argue that nationalism could combat global climate change. Previous research on how
nationalism is implemented in environment and climate politics has mainly focused on single
parties. The thesis therefore aims to give a broad approach and compare how nationalism is
used in environment and climate politics by analyzing 4 European parties with either ethnic or
civic nationalism and different roles in their party system. With a qualitative content analysis
on party programs and election manifestos the findings imply that parties use nationalism in
the climate and environment discourse in a variety of ways.
OMBYGGNAD AV TRAFIKPLATS : Ekhagsmotet i Jönköping
We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.
Hållfasthetsegenskaper i gjutjärn : tensile properties of cast iron
In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

EU:s klimatpolitik - förhandlingsvägen till framgång
Eleven years after broking the Kyoto-protocol, the European Union still stands in the front line, combating climate change. How come the EU, with 27 diversified states, is able to integrate its members to what is widely considered the most progressive climate policy in the world? This thesis takes a closer look at the negotiations that have shaped EU climate policy. Using negotiation-models to categorize different aspects of EU climatenegotiations, several key-findings are presented. The thesis concludes that while EU entered the Kyoto-protocol with little to lose because of external factors like previous energy-reforms in key member countries, it had plenty to win in global influence and the satisfaction of an overwhelmingly Kyoto-positive public.
