There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

The margin in crop production is more and more less and it forces the producer to check out how to reduce the cost of establishment of new crop. One way to reduce the cost in establishment is to begin with plough less farming. It saves money and time compares to conventional soil preparation with plough and harrow. Not all soil types are god for plough less farming and should be continued with ploughing (mainly light soil), but other soil types working very well with plough free farming. If you want to success with plough less farming you have to think in new lanes. One of the things you have to think about is to not grow too much cereal after cereal. Low stubble is important when you harvest the crop and also to spread and chop the straw well. I have in this work interviewed some farmers and farm advisers in Östergötland to see which thoughts they have about plough less farming.

The research of the essay will be about Solidarity, the Polish trade union that began to rise in the beginning of 1980. In more specific tendencies to the empirical study, it is interesting getting to know about when the free trade union was created with a view to liberate the Polish people from Communism.The essay will be studied as an empirical case study, with a qualitative text analysis. The content will also include how power is allocated to the political, economic and social aspects of the national, and international relations. Therefore it will be relevant to use a method of ideology analysis to the qualitative text.The result of the theoretical analysis was that it is difficult to apply the social movements into a political change, even if it leads to success. According to this, participants in social movements are able to use the most potential and most necessities of resources, just as activists tend to do in reality..

Det övergripande syftet med uppsatsen är att diskutera och analysera de val av belöningssystem för anställda som arbetar i team, som har gjorts vid SEB. Analysen bygger på material inhämtat genom intervjuer med chefer och anställda vid tre olika avdelningar inom företaget. Samtidigt som vår analys, byggd på vårt val av teoretisk referensram, tycks peka på att valen av belöningssystem vid två av de tre undersökta avdelningarna skulle kunna ifrågasättas, har våra respondenter inte uttryckt någon önskan om att radikalt förändra dagens belöningssystem. Vi anser därför att såväl företag som forskare bör fundera över vad syftet med användandet av belöningssystem är. Beroende på om man anser att belöningssystem primärt är till för att teammedarbetarna ska känna sig nöjda och motiverade, eller att belöningssystem är till för att öka teamens effektivitet och produktivitet, kan slutsatserna om hur man bör belöna team se olika ut..

Föreliggande uppsats syfte är att utreda huruvida Sverige är i behov av en moderniserad och mer internationellt anpassad avtalslag. För snart tjugo år sedan ratificerade Sverige den internationella köplagen United Nations Convention on Contracts for the International Sale of Goods, CISG, med reservation för konventionens del II om ingående av avtal. Detta eftersom Sverige tillämpar löftesprincipen vid ingående av avtal och CISG utgör en kompromiss mellan löftes- och kontraktsprincipen. Sverige är tillsammans med de övriga nordiska länderna ensamt om att reservera sig mot denna del och har därför av andra staters näringsliv kommit att ses som provinsiellt samt bakåtsträvande. Den globala handeln blir allt viktigare för Sverige och det svenska näringslivet har till följd av detta ställt krav på landets ledande makthavare att dra tillbaka reservationen och att anta den avtalsrättsliga delen.

Purpose: The purpose of this thesis is to investigate whether abnormal stock returns could be identified as a result of a layoff announcement during weak economy.Method: An event study methodology.Theory: Efficient market hypothesis, signal theory.Empirical results: Quantitative data from observations of stock prices in thirty two companies listed on the Nasdaq OMX Stockholm, in the period 2008 -2012.Conclusion: The results indicate that the market reaction was negative because there were negative abnormal returns on the Stockholm Stock Exchange during the period 2008-2012 in connection with the layoff announcements. The market reaction was milder when staff reductions were carried out as a result of a restructuring and stronger when staff reductions were carried out as part of a cost reduction program.The layoff announcements elicited different market reactions depending on the company's industry affiliation. The most negative reaction was in the Healthcare industry. Negative abnormal returns were lower in industries Industrials, Consumer Services and Consumer Goods. There were no abnormal returns for shares of companies in the industry Financials.

The aim of this thesis is to form a theory of the green consumer power and to distinguish whether this phenomenon could indicate a movement toward the ecological citizenship. To do so, scientific theories regarding the responsibility of companies have been used, as well as the public choice theory, to link individuals as citizens to individuals as consumers. The motives of corporate environmental responsibility, along with consumers ability to bring pressure in different dimensions, are later drawn on as indicators applied to empirical information. The largest producer of ecological products in Sweden, Arla Foods, is employed as case study to explore if the green consumer power can and does exist. The ecological citizenship uses the ecological footprint, to define in what ways we can minimize our part of environmental degradation.The study seems to strengthen the theory, consumers do have a power to make companies go green and they tend to use it increasingly.

Sandvik Wire needed a review of the administrative part of the order fulfillment process and especially the work around packing and the inventory of finished goods. Therefore we acquired the assignment to investigate the administrative part of the order fulfillment process in the company with the purpose to identify potential for improvement. This investigation was performed with focus on the terminal and packing functions. The purpose with the investigation was also to identify critical factors for an efficient order fulfillment process and investigate if information quality is such a factor.Data was collected through interviews and observations on Sandvik Wire. With the help of this data the information and material flows was mapped, the work within terminal and packing, and adjacent functions was investigated.

Theft without break-ins has increased significantly in the last year of swimming, sports and leisure facilities in Karlskrona, more precisely 60%. Vandalism in the shape of graffiti is another common crime. The solutions are divided into social and situational crime prevention. Social crime prevention engage in actions that are based on social causes of crime rather than the opposite situational crime prevention, which instead assumes that discourage with the help of technical solutions and has as primary objective to hinder accessibility for example theft friendly goods. The main purpose of this work is to come up with solutions to prevent these crimes, while also being cost-effective and realistic to implement.

The purpose of this thesis is to study the level of democracy within the European Union (EU). To do so the following issues were examined: How the EU works and the efforts it has made to improve levels of democracy; and the degree to which the EU fulfils the criteria set by Robert Dahl in his theory of polyarchy.The study is based on a qualitative text analysis. The focus of the analysis is documents released by the EU that can be connected to democracy, and human and fundamental rights. The theory of polyarchy proposed by Robert Dahl and Joseph Schumpeter?s theory of democracy are the principal theories applied.

AbstractThe purpose of this study is to answer the following questions regarding confirmation: In what ways do children seek confirmation in preschool? What are children confirmed for and how do they react to the confirmation? How is confirmation used by teachers? What do children want to receive confirmation for?The starting point for this study is based on the unique theories of Skinner, Maslow and Bronfenbrenner. The main focus with regard to Skinner?s theory (in this study) lies in reinforcement. In Maslow?s theory, the concentration is on hierarchy of needs while in Bronfenbrenner?s theory, the study centers upon interaction.

Detta examensarbete har utförts hos Norrskog Wood Products AB (NWP AB) som omfattar fyra sågverk och tre hyvlerier i mellannorrland. NWP AB bildades 2004 när Skogsägare-föreningen Norrskog köpte Camforegruppen i Jämtland och fusionerade den med sitt tidigare helägda sågverk SAEF AB (Östavallsågen). Vid årsskiftet 05/06 förvärvades det tredje hyvleriet som ligger i Forsa utanför Hudiksvall. I dagsläget när företaget fortfarande är relativt ungt sker det mesta av transportplanering och fraktbokningen vid varje enhet och man gör som man tidigare har gjort. Syftet med examens-arbetet är att för en bestämd period, 2005-01-01 till 2005-05-31, kartlägga transporter och kostnader från industri till kund för hela NWP AB.

The main purpose of this essay is to look closer at how and when the Swedish women?s organization Grupp 8 changed their initial socialistic ideological approach and turned it into a feministic one during 1971 to 1979.
