The thesis demonstrates a low-cost, low-bandwidth and low-resolution Analog-to- Digital Converter(ADC) in 0.35 um CMOS Process. A second-order Sigma-Delta modulator is used as the basis of the A/D Converter. A Semi-Uniform quantizer is used with the modulator to take advantage of input distributions that are dominated by smaller-amplitude signals e.g. Audio, Voice and Image-sensor signals. A Single-bit feedback topology is used with a multi-bit quantizer in the modulator.

Title: The auditor?s recommendations to small businesses in the choice of K2 and K3Authors: Christopher Dimovski and Dennis Carlsson Published: Spring 2014 Background: The background of this study is the introduction of the new K-regulations. For small businesses, there is a possibility to choose between the rule-based K2 and the principal-based K3. It becomes mandatory to apply the K-regulations from 2014. We want with this study understand and explain the significance of the auditor and its recommendations to small businesses in the choice between K2 and K3. Aim: The aim of this study is to describe how the auditor makes recommendations to small businesses in the choice between K2 and K3 and through that create an understanding of what influence the auditor have when it makes recommendations and at the end contribute to the building of models. Formulation of problem: How can we understand and explain the auditor?s recommendations to small businesses in the choice of K2 and K3?Methodology: We have used a qualitative method where we have interview eight auditors.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

High housing- and construction costs is a fact in Sweden today. Prices on building materials more rapidly than producer price index for industrial goods. Prices tend to rise during market boom but does not adapt during diminishing demand. The effects of fading demand can rather be deduced through discounts and quotations. During 1992-1998 when the Swedish construction sector found it self in severe crisis the prices of construction materials kept rising more rapidly than PPI for industrial merchandise.

During the past year it has been made possible to buy back a company?s outstanding stock. This is done in order to change the capital structure towards a situation with less equity. A change in capital structure means a change in the cost of capital for a company and by that a change in the value for the stockholder. This Master Thesis studies the relation between capital structure and business risk.

Inledning: Mycket diskussion har förts kring nedskrivningsprövningen av goodwill och de tydliga element av subjektivitet och bedömning som den präglas av. Då mer subjektivitet kännetecknar värderingen av goodwill än andra tillgångsposter leder det till att ledningen kan påverka nedskrivningen i större utsträckning än vad gäller nedskrivningen av andra tillgångar. Syfte: Studien syftar till att jämföra en teoretiskt framräknad diskonteringsränta och företagens egna diskonteringsränta, och en eventuell skillnad mellan dessa diskonteringsräntor. Ett antal förklaringsvariabler kommer undersökas för att se om dessa kan förklara en eventuell differens.Metod: I studien har en kvantitativ undersökningsmetod använts där redovisningsmässiga siffror har hämtas in samt studerats med hjälp av CAPM-modellen.Analys och slutsats: Analysen fastställer att det förekommer en skillnad mellan redovisad och teoretisk diskonteringsränta. Studiens slutsats är att det som är mest bidragande till de kraftiga skillnaderna mellan diskonteringsräntorna är utformningen av IAS 36. Detta beror till största del på att värderingen av goodwill baseras på osäkra antaganden och bedömningar. Förslag till vidare forskning: Förslag till vidare forskning är att göra en liknande studie men över en längre tidsperiod eller undersöka andra faktorer i nedskrivningsprövningen än diskonteringsräntan.

The main reason for this project is my interest of our environment. What are our two largest grocerychains doing to maintain our environment? The aim of the project is to show the consumer which similarities and differences there are between ICA and Coop. My questions are: What are ICA and Coop doing to satisfy the demands to preserve our environment, are they going further than they have to? What do they think is important? Environment, price, consumer friendly? Answers: ICA and Coop are working to keep up with the demands, but are they doing more than they have to? The branch is a close world; it's hard to get impartial information. They are turning towards different consumer groups. ICA and Coop has different ways to interest consumers, ICA points out the importance of the meals, while Coop points at the environment. New questions has risen during my work: How far will their own brandnames go? Will ICA, Coop and others have their own farms, producers and suppliers? How can the consumer be protected? The competition will decrease with an increase of their own brandnames..

The goal of this paper is to provide a model for a sustainable electricity system to an island, in the Pacific Ocean near the equator.The method which has been used is to model supply and demand of electricity in the computer program Stella, through the creation of a dynamic system that balances them against each other. The result from the model will then be used to calculate the electricity price per kWh for the island.The result of the work is that electricity from solar energy is comparable with electricity produced from oil, if the oil pays for all its external costs, and the potential for pumped hydro storage plants is located. It also requires that consumers of electricity can be their own producers to avoid the expenditure of tax and reducing the cost of distribution. But since oil is a finite resource and has had a rising cost in recent years, while solar energy has had a declining cost, perhaps this will be a more competitive solution in the future.

Although previous research conclude that mergers and acquisitions do not always lead to improved profitability or increased shareholder return, the number and size of M&A?s is steadily increasing. In this thesis we examine why an acquirer pays a price higher than the market value. Can accounting data explain the size of the premium? 618 European transactions between 1997 and 2008 are examined and relationships between the targets? accounting data and the premium is analysed through statistical regressions.

Med företagets kapitalstruktur avses den mix av eget kapital och skulder som används för att finansiera företagets tillgångar. En faktor som anses påverka valet av kapitalstruktur är den typ av tillgångar som företaget har. En hög andel immateriella tillgångar är förknippade med en lägre skuldsättningsgrad. Syftet med denna uppsats är att undersöka om det finns ett samband mellan andelen bokförda immateriella tillgångar och skuldsättningsgraden hos svenska börsnoterade företag i IT-branschen. Ett delsyfte är undersöka om det finns något samband mellan affärsrisken samt företagens storlek och skuldsättningsgraden.

The society of today can?t manage without transportation. We need transports to getfood, to go to work and to create new products. The transportation ofgood is thus an important part in the function of the society and they?ll increase, bothin number and in amount.

This examination work is the final work in our education to become a Bachelor of Science inMechanical Engineering by the University of Lund.The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all machines with unit-, semi- and finished goods during full production. The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.

The purpose of this paper is to examine and analyze past development of mutual funds in large and small mutual fund companies and see if there are any differences between these two segments. Limitations on the number of funds have been made by choosing Nordic mutual fund companies that invest in emerging markets over an 11-year period. The study is made on 66 mutual funds managed by 13 mutual fund companies in which the segment of small fund companies includes seven fund companies with assets under management less than 100 billion SEK and the segment of large mutual fund companies includes six fund companies with assets under management more than 400 billion SEK. In the comparison of the segments the Sharpe ratio has been used to calculate the risk-adjusted return. The study shows small differences of the risk-adjusted return between the segments.

The aim of this study was to examine retiared individuals view of oral health and dental care. A questionnaire was sent to three different retirement organizations and answared by 106 participants. Our studie showed that irrespective of education or health status, the majority considered oral health and dental care was important and will become so in the future. Most elderly individuals can consider getting help with their oral health with oral health care in the future. This studie showed that the elderly are concerned about their appearance.
