Fundamental indexering - fundamentalt rätt?? : En studie av den svenska aktiemarknaden
I denna undersökning konstrueras fundamentala aktieindex med aktier innefattade av indexetStockholm OMX30 under perioden 1999-04-01 till och med 2009-03-31. Dels konstruerasenskilda index där indexeringen sker efter faktorerna bokvärde, utdelning, försäljning, resultat,kassaflöde och antal anställda, dels ett index där faktorerna sammanvägs. Detta för att undersökahuruvida fundamentala index bättre speglar företags fundamentala värde och därmed genererarhögre riskjusterad avkastning i förhållande till ett marknadsvägt referensindex. De enskildaindexen bokvärde, utdelning, försäljning, antal anställda samt det sammanvägda indexet visarhögre riskjusterad avkastning än referensindexet. Kassaflödes- och resultatindexet presterardäremot markant sämre än referensindexet.

Filterdesign och hårdvarukonstruktion för FMCW-radar
Den här högskoleavhandlingen beskriver designen av ett IF-filter samt hårdvarukonstruktion av en ny 77 GHz FMCW-radar demonstrator. Syftet med demonstratorn är att illustrera hur kisel germanium-, SiGe, teknologi kan användas istället för den mer vedertagna men dyrare gallium arsenik-, GaAs, teknologin. Den gamla radar-prototypen vilken Acreo AB utvecklat är funktionell men behöver konstrueras om för att bättre kunna utvärdera radarprestandan. I avhandlingen presenteras grundläggande radarteori och ekvationer för att underlätta förståelsen av de olika systemblocken. Rapporten beskriver också systemarkitekturen och hur dess funktionalitet kommer att testas.
Hur tränas hundar inom svenska brukshundklubbar? :
This is a descriptive paper based on a questionnaire- and literature study regarding how dogs are trained, what type and frequency of injuries that occur as well as how the dogs are best prepared for work. Using the results from the questionnaire, an overview is given on how members of Working dog clubs train their dogs and what kind of injuries that occur most frequently. The average age among the dogs included in the study was only about three years. This could indicate that older dogs are not trained in the same extent as young dogs. The results show that only a third of the dog owners warmed up their dogs before training.
Läsinlärning och läsförståelse : Sju pedagogers erfararenheter i undervisningen med läsinlärning och läsförståelse
This thesis is based on qualitative text analyses of four works of fiction, used as teaching materials in the school subject of Swedish, from a queer theoretic perspective. The purpose of the study is to examine how sexual identities and expressions are being presented, as well as what positions are offered a reader, in relation to the heterosexual norm. Basis for this thesis are the schools fundamental values, which highlights the importance that intolerance be confronted through both knowledge and active measures, and the syllabus, which states that fiction should be viewed as a tool for identity development as well as an understanding of the outside world.The analyses reveals a distinct connection between the generally accepted heterosexual norm and a professed (or taken for granted) heterosexuality which is being carried out by the characters or the books as a whole. Out of the four titles only one disputes this norm, by offering a wide range of sexual identities and expressions. These expressions, however, are being invalidated ? through insufficient ability to relate to the norm ? or made invisible ? through an imagined heterosexuality which, by superiority over other expressions, excludes them..

Undersökning av modulationsscheman för existerande bredbandsteknologier
In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.
Svensk vapenexport - varför (inte)? : En undersökning av för- och motargument till Sveriges export av krigsmateriel
Title: Det nya Ryssland - En inblick over Rysslands utrikespolitik under 2000-taletAuthor: Tim Balder and Jens KindhLinnaeus UniversityDepartment of Political ScienceAutumn term 2011The purpose of this thesis is to gain a better understanding of how the Russian foreign policy is, how it is conducted and how it may develop in the future. To do that, we are going to try to answer the following questions:What characterizes Russia's official foreign policy?What theories are there for the Russian foreign policy?How can the various theories explain the Russian foreign policy actions at the international level?Our theory is to try explaining how the Russian foreign policy is continuing its development during the 21st century through three theories known as the Western liberalism, Pragmatic nationalism and Fundamental nationalism. Furthermore, to explain Russia's foreign policy and their behaviour, we are going to use the two foreign policy doctrines from 2000 and 2008.

Grälsjuka svenskar : En undersökning av verbala konflikter i två svenska 2000-talsfilmer
The purpose of this essay is to highlight the conceptions that exist in school towards homosexuality. My overall essay questions are: What rules does the school have to apply concerning homosexuality? What approach do the professors have towards young lesbian women and kind of support is offered to the group? In order to answer these questions I interviewed a professor and a young lesbian female. One of the surveys that has been made, as a normative order, about heterosexuality in the last decade is known as queer theory.One of the theories that in surveys investigates homosexuality as a normative order is known as ?queer theory? and it is the one I decided to use in this essay.Inspired by feminist research, gay and lesbian studies and the poststructuralist theory, the queertheory focuses on some peoples way of organizing sexuality is privileged, sanctioned and is perceived as normal, while others are seen as deviant, abnormal and therefore unwelcome.

Förbränningslära för bubblandefluidbädd
Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report, the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.
Industriellt köpbeteende av utlandsresetjänster
The purpose of this thesis is to examine the organizational buying behaviour in the purchase of travels abroad. We have conducted a case study of two companies, one medium sized and one larger. Our empirical studies have shown that the companies? buying process is divided into two types, the process of recruit a new travel supplier and the process of a straight rebuy of a regular travel service. In the recruiting process we found that the evaluation process of the purchase is an ongoing process that contradicts estab-lished theories.
Innovate or Evaporate : -En kvalitativ studie av idéhantering på IKEA AB
The thesis focus on how organizations can improve the ability of absorbing coworkers ideas in purpose of gaining long term competitive advantage through innovations. The study was conducted at IKEA AB where a campaign to collect coworkers ideas was a big success given the quantity of ideas collected. This fact allows a comparative analysis of idea management in the shape of campaigns and in comparison, idea management in the everyday line-organization.The analysis show that fundamental factors for innovative environments such as organizational climate, culture and leadership perceives auspiciously by the respondents. However, lack of infrastructure such as systems and processes hinders coworkers ambitions to contribute with ideas.An important issue in idea management is the treatment of incentives for innovation. Results of the study show that the ?soft? incentives ?feedback, encouragement and attention have a higher impact in coworkers willingness to the contribution of ideas than for instance monetary rewards..
