This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..

Tidigare forskning har visat att systematisk självrapportering är en fördelaktig metod för att följa enpersons psykiska mående över tid, och att en digital mätmetod i sin tur skulle innebära många praktiskafördelar jämfört med en analog. Detta är en experimentell randomiserad, kontrollerad studie som medutgångspunkt i personcentrerad vård och spelifiering undersöker 35 personers användarfrekvens ochattityder efter en tvåveckorsperiod där hälften har fått prova att självskatta sitt psykiska mående via enmobilapplikation, och hälften fått göra detsamma via ett analogt stämningsformulär. Resultatet visar enhögre användarfrekvens bland deltagarna i mobilapplikationsgruppen, samt ett uttalat intresse hosbägge grupper för digitala metoder för självskattning av psykiskt mående. Bägge metoderna ansesstärka personcentrerad omvårdnad. The aim of this study is to explore user frequency and attitudes for persons using a mobile applicationfor assessing mental health compared to persons using an analogue assessment method.

There is a clear difference between the way football players and leaders regard the role of the referee, compared to the way the refereeing body looks at it. The refereeing body regard themselves as fundamental for the existence of the sport, while the other mentioned parties merely see them as functional justice makers. This view places the referees outside the field of football. This establishes a football culture, which is conflicted when it comes to the role of the referees on the field. The conflict comes to its edge in youth football, where the referees are under severe pressure.

This master essay is about teenagers, alcohol and the preventing measures taken by the Swedish government. Consequences of the rising consumption of alcohol among adolescents and how to prevent dangerous alcohol consumption in the future is one of the most prioritized issues in the Swedish society today. Today there is no prevention that clearly shows any effect on teenager?s alcohol consumption and the education about the dangerous effect of alcohol is clearly not the same in schools around Sweden. To gain knowledge about how teenagers view their own consumption of alcohol we have used the Grounded Theory.

This work examines the students´ thoughts on climate change with a focus on carbondioxid through photosynthesis and the carbon emissions from cars. The study is based on two subject areas, one with a focus on enhanced greenhouse effect, and the other focusing on photosythesis. The survey was conducted by means of qualitative interviews with students in grades four and six. The results describe that student´s understanding for photosynthesis and the carbondioxids function for photosynthesis doesn´t change significantly from grade four to grade six. I have divided the students inte three levels based on their understandingof the various fields, and their use of adequate concepts.

The main purpose of this thesis is to analyze why or why not Swedish municipalities implement the gender equality policy ? ?right to work fulltime?. In order to understand this institutional change, the analysis is based on a theoretical framework consisting of two fields: political representation and feminist institutionalism. The study is divided into two empirical inquiries. The first part is based on a quantitative survey that describes the casual relationship between two independent variables; women´s political representation and party ideology, and the dependent variable; political decision about ?right to work fulltime?.

The swedish healthcare is in many situations one of the best in the world. But still, the healthcare system includes elemnts that reduce the efficiency. Partly becouse the swedish healthcare is largely monopolized, the servicecs are not properly prized and the economic responsibility and the liability legislation is limited. The main problem this study evolves around, is how a different liability rule would change the shape of the healthcare organisation. Abouve all, how would the approach to riskmanagement and preventive and riskreducing performance change with a diffrent liability rule.

This thesis is composed within the framework of the supplementary course in psychotherapy concentrating on family therapy (60 credits) arranged by Lund University's affiliate in Västerås, Sweden.The purpose of this thesis has been to explore how the idea to initiate evidence based methods in the workings of the Individual and Family Care Department of the City of Västerås was born. Furthermore the thesis will explore if consideration for methods of theoretical implementation are implied. The study assumes a qualitative attempt and is based on semi-structured interviews from three levels within the organization, including both management and operation.Theories on organization,implementation and the theory on change strategies have been used as a theoretical starting point.The study result shows that introduction of evidence based methods in the City of Västerås is based on the experiences of the organization regarding the need to develop and increase social services contributions to non-institutional care. Experiences from expensive transferrals to institutions which only occasionally produced satisfactory results were a contributing factor. New published research and a strong interest and desire inside the department to improve and change social services contributions have naturally been a positive influence for the development.

Actors deliberately change their preferences, contrary to the assumptions of rational decision models. This study shows why, and to some extent how. Preferences are necessarily ambiguous and unstable. Rationality is a regulating myth which has had a profound influence on Western conceptions of what an actor is.The aim of this study is to help individual actors understand the theoretical grounds of their actions. The analysis provides tools for examining decision methods and preference changes.

It is a well known fact today that suffering due to skin disorders is one of the most common causes to veterinary calls. For the Doberman breed included in the group of working dogs, the frequency and distribution of the different skinrelated diagnoses that causes visits to the veterinary clinics remains undocumented. The purpose of this study was to evaluate the frequency of skinrelated problems causing veterinary visits of Doberman at four different veterinaryclinics in Sweden retrospectively, and compare these results with dogs in general and three other working dog breeds with the help of information collected from Agria - a Swedish animal insurance company. The total amount of veterinary calls that were registered at the clinics in question during the time of the study was 2460 visits. From these, 658 visits were due to skinrelated disorders, which amount to 27%. The most frequent cause to skinsuffering was injury caused by trauma, 15,7% of the Dobermans that were included in the study were affected, the second most frequent cause was inflammatory and infectious skin problems with 12,3% followed by neoplastic changes in the skin with 7% of the Dobermans affected.

Intangible assets are often a significant part of Swedish companies? assets. Most of these are accounted for as goodwill, arising from acquisitions. After EU:s decision to adopt IFRS as the new accounting standard, intangible assets will to a larger extent be recognized separated from goodwill. This thesis aims to quantify this change and to analyze what specific intangibles are affected most by the transition to IFRS.

This study explores Sweden's climate change denial by analyzing the spoken-word discourse of its countermovement, focusing on digital media content from Swedish parliament member Elsa Widding with an aim to provide empirical insights into the discourse of Sweden's Climate Change Countermovement (CCCM). Questions guiding this study are: What are the most prevalent topics and themes related to climate change denial and skepticism? How do they align with established categories of climate change denial, shaping the overall narrative? What mobilizing ideas and meanings are present, how are they shaped, and how do they contribute to the movement's goals? The material consists of Elsa Widding's complete audio-based "movement texts'' from 2019-2023, including YouTube content, podcasts, and appearances on Riks, totaling over 2000 minutes of audio transcribed into text via AI technology. Methodologically, this study adopts a mixed-method approach which blends computational pattern detection, topic modeling, clustering, and spatial relationship mapping techniques, along with qualitative content and framing analysis. Theoretically, the study employs a perspective which uses epistemic and response skepticism to examine climate change denial, viewing it through the lens of countermovements and social movement framing. The study's main contribution lies in the enablement of comprehensive analysis of a large audio-based dataset, achieved by leveraging recent AI advancements for reliable audio-to-text conversion combined with topic modeling.

The purpose of this Bachelor degree project is to design different types of services that can increase the amount of re-used timber within the building sector and by that means improve their environmental efforts. By examining how the sectors environmental work concerning recycling and re-using timber as a building material is getting on at present, conclusions have been drawn about what further could be done for improvement.The project has shown that there is a scarcity of information and statistics within the sector, but that there are efforts in progress to change this. Questionnaires have been sent to a number of companies working with demolition and utilizing re-usable materials in order to find out what kind of problems there are within the trade. Unfortunately the survey gave insufficient result due to the low reply frequency.It is obvious that active environmental work within the building sector is important and the knowledge acquired while working with the project has led to the design of three suggestions for services regarded as being of interest for improving the negative environmental impact caused by the sector:Suggestion 1 ? Sale of construction parts prior to the demolition of a buildingSuggestion 2 ? Re-utilization circulation when manufacturing buildingsSuggestion 3 ? Education in relation to the purchase of houses  The positive and negative qualities of the suggestions have been examined with SWOT-analysis and further adaptions and the results have been interpreted.

The following essay studies the change in the use of terminology pertaining to socioeconomic categorising in public political material, and how this relates to ideological changes in politics. The aim is to determine which expressions government commission reports have used after the Second World War to classify citizens in social and economic groups, and subsequently, to link the understanding of these terms to the development of Swedish welfare politics. Welfare politics in Sweden have experienced a transition in a liberal and economistic direction that is reflected in the commission reports? choices of words and phrases ? thus studying the altering terminology can increase understanding of the ideological change. My methodology is grounded in ideology critique where I examine how dominant ideology is reproduced in public political documents.
