Ska vi byta väder? -Väderderivat som riskhanteringsinstrument

Background: As a result of the financial markets ever ongoing product innovation a new derivative was introduced in the USA in 1997. A derivative that derived it's value, not from the price of an underlying asset, but instead from a climate factor. It's been known for a long time that revenue in certain industries are affected by weather conditions. The suppliers of weather derivatives claim that these weather sensitive businesses can user weather derivatives in order to lessen weather risk. Purpose: To do a critical evaluation of how weather derivatives can be used by companies as a risk management tool.

Samband mellan luftföroreningar och klimatfaktorer - en statistisk unersökning

That air pollutants of different kind has impact on our climate can hardly haveavoided anyone during the past years environment explosion in the media. But howis it actually with the reverse, i. e. the climate's impact on air pollutants? The aimwith our degree thesis is to try to find out if different weather factors, statisticallyseen, promotes atmospheric pollutants and particles in the air and vice versa.We got access to data on air pollutants and weather factors that was registeredduring year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.In order to do a statistical investigation of these data, and to be able to analyze if itoccurs relations of various kind, we used the statistics program SPSS.

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.

Indianen och kalla kriget : Audiovisuella representationer av kalla kriget 1965-1986

The similarity between the Russian and the Indian, in a Cold War context, may be ambiguous considering the ethnic-social variables and the period in time from where the Indians relate. However, by analyzing these, as well as other, characters in the exhibition of movies, we could learn something about the ideology of the time from which the movies derive.This study examines ideology and movies in the Cold War era and concludes that the Indian, for example, may be representing the values of the common public enemy, originating from the Cold War ideology. The movies examined, regardless of influence of distinct Cold War themes or lack of such themes, carry attributes that give evidence of typical Cold War ideology. The fear of communism and common enemies connected to a Cold War context, the thought of America as the land of the free ? with the horizon in the ending of the movies as metaphoric to freedom ? and the moral rhetoric that connects to the American thought of a duty as a global savior, are all signs of the Cold War ideology.Even though the messages are somewhat clearer and more distinct in the movies with Cold War motifs, the fact that ideology is projected through other movies as well should be considered essential for the continuing study of movies as cultural artefacts..

Vädrets påverkan på byggarbetsplatsen

This exam report contains studies about how the weather affects the construction site from a planning and productivity perspective. In 1960?s the contractors started to build during the winter, since then the demands to obtain a good construction has been higher on both the contractor and then promoter.In this report you will see how the different actors at the construction site handle the weather problems. By several interviews of the actors at the construction site there have been opinions about the weather situation which has been collected. To get a wide perspective of the problem, field studies from four different construction sites been made.Weather statistics over Halmstad is a mayor part of this report.

Statistisk kartläggning av dimma längs E4:an mellan Helsingborg och Jönköping

Fog is a small-scale weather phenomenon that are fascinating to people. However, the presence of fog in road traffic reduces the visibility and increases the risk of road accidents. By the Swedish Road Weather Information System (VViS), the safety on roads could ameliorate and road accidents caused by fog and other weather hazards could be prevented. Fog is however a complex and usually local phenomenon, why fog formation generally is not easy to predict. For that reason, a statistical mapping of fog, especially along a motorway with high traffic volumes, could be useful in planning to prevent road accidents.

Personsäkerhet vid väderskyddsbyggande : En kartläggning över dagsläget och problematiken med frånvaron av föreskrifter i branschen

This paper, Personal safety when working with weather encapsulation constructions, is focused on weather encapsulation constructions and how the absence of Swedish standards and regulations is affecting the safety for the workers. The usage of weather encapsulation construction is increasing in Sweden therefore the needs for standards and regulations are becoming more and more urgent. The risks involving the rising and the demolition of the weather encapsulation construction and when the construction is transported along its rails are treated in the paper. Since there are no regulations companies have had to solve the safety issues without instructions, the paper regards how the companies have solved this problem without the support of formal institutions..

Tillverkarnas syn på utvecklingen av väderskydd

How does the weather protection systems look like today, and how will they be developed in the future? These are questions that we have worked with during this project. At the start of our report there?s a summary of the leading weather protection manufacturers in Sweden. We have explained how these systems are constructed and how they work.

Historiografi och paradigm i forskningen om kalla kriget : En komparativ analys av diplomatihistoria och internationella relationer

Adopting a socio-cultural approach to the study of cold war historiography, this master?s degree essay is a comparative study of the two main disciplinary fields of cold war scholarship, diplomatic history and international relations theory (IR). The study applies the theory of scientific development formulated by Thomas Kuhn and the concept of paradigm on the field of cold war research.Diplomatic history and IR shows many similarities in their development, and in the importance different schools has had in scholarly debate. These different schools are analysed as paradigms, a concept that has been more willingly adopted within IR than in diplomatic history. The transition from what historian John Lewis Gaddis has termed Old Cold War History to New Cold War History is discussed in terms of paradigms and paradigm shift.

Drivenhet för satellitantenner

The task in this master thesis was to design and construct a prototype of a satellite antenna driver unit. The unit is to be robust and work in cold weather down to -40°C, so that it can be mounted on the roof of a minibus. A microcontroller controls the H-bridges simultaneous, each connected to an electrical motor. Hardware and software protections were implemented to ensure that the antenna can not turn outside its allowed area and risk breaking. The unit can output voltages at many different levels and communicate at a multitude of signal standards..

Valsningsteknik för extremt höghållfasta tunna stål

New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.

Naturligtvis : en studie om naturens betydelse för ungdomars hälsa

The aim of this study was to investigate the importance of nature for the health and well-being of young adults. A qualitative method was used and data was collected through semi-structured interviews with eleven people from the ages of 15-20. The interviews were transcribed with the results of the study revealing that nearly everyone felt calm and relaxed while they were in a natural environment. The most common motivation to be outdoors was socializing with friends, performing any kind of sport and/or taking walks. Reasons to stay indoors were rainy, cold weather, lack of time, and in some cases circumstances related to their surroundings, such as where they live.

Betydelsen av hästens hud och päls för reglering av kroppstemperatur i kyla ? vad händer vid klippning och täckning?

The horse is a homeothermic animal and to keep a constant body temperature in winter season is important. Acclimatisation is to provide means for a good thermal insulation consisting of skin, hair, and an outer air layer. The skin covers the horses body and it is composed of three main layers where the top layer of the epidermis consists of dead keratinized cells that are constantly being sheed. The dermis is composed of collagen connective tissue that give the skin its strength. The bottom layer with subcutaneous fat provides a thermal insulation and can be used as an energy reserve in cold weather.

Kommunismens ansikte : Skildringen av kommunismen som ideologi och kommunistiska regimer i svenska och norska gymnasieläroböcker under perioden 1951-2011

This paper presents an analysis of history textbooks used in schools in Sweden and Norway. The intention of the research was to study how the history textbooks describe communism and communistic dictatorship mainly during the cold war. The result of this study is that there were no big differences between Swedish and Norwegian history textbooks, but there are, however, some differences in how communism was described between the authors and also over time. Mostly, the books that were written in the post cold war period were somewhat more critical to communism in the eastern Europe (even thought they mainly handled with Stalin´s communism. And they also set quotationmark between Stalin´s communism and the nazi terror during World War two..
