Analog-to-Digital Converter Design for Non-Uniform Quantization

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.

Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem

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..

Kostnadsuppföljning avproduktionskalkyler

Calculations are an important part of planning around a construction project. From concept to completion of the project calculation is a tool to try to predict the actual cost. During the production stage in particular, deviations occur which makes the actual cost different from the calculations.This thesis is done in collaboration with JM Residential Stockholm. The study includes a cost follow-up in which a comparison was made between the calculated production cost and actual cost for the five projects. The aim of the study was to observe the most common reasons that a project deviates from the calculated production cost and then summing these causes in a number of categories.

Smartphoneutveckling förflera plattformar

Marknaden för de allt populärare smarta telefonerna är splittrad. Detta innebär nya utmaningar för utvecklare. Vill man vara säker på att nå mer än hälften av sin målgrupp med en mobilapplikation så måste man utveckla för minst två plattformar, något som kostar både tid och pengar. Ett antal så kallade multiplattformsverktyg har tagits fram för att lösa detta problem. Dessa låter utvecklare använda en och samma kodbas för flera olika plattformar.

Taiwan och Kinas relation över sundet - självständighetsledaren Chen Shui-bian

Uppsatsen redogör för förhållandet mellan Taiwan och Kina, den så kallade "relationen över sundet", och koncentrerar sig på åren 2000-2008 då Chen Shui-bian varit öns president. Chen anser Taiwan som ett suveränt, självständigt land, medan Kina anser att Taiwan borde acceptera "ett-Kina" principen, som innebär att Taiwan är en del av Kina. Uppsatsen undersöker om, och i så fall hur, Chens tid som president har inneburit förändringar i relationen över sundet..

Kriskommunikation i ett senmodernt samhälle ? exemplet Svenska Röda Korset

The purpose of this study is to examine how an organization communicates during a crisis and how a crisis can affect an organization's reputation/credibility in late modernity. The focus is on how the Swedish Red Cross handled crises from summer 2009 until spring 2010, and how the organization's reputation/credibility was affected by the fact that society has changed. The methodology used is a quantitative and qualitative text analysis. The results show that crises affect organizations, how much depends on how open they appear to be and how much credibility they have with them when the crisis begins. Getting to know the late modern society, to understand how it works, can bring benefits to an organization during a crisis.

Kapitalstruktur och Affärsrisk

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.

Sjukvårdspersonalens compliance gällande hygienrutiner

Vårdrelaterade infektioner kostar årligen 3,7 miljarder kronor och drabbar 10 % av dem som ligger inne för akut sjukvård. Det är därför viktigt med en god vård-hygien. Syftet med studien var att undersöka hur väl vårdpersonal följer Handbo-ken för hälso- och sjukvård då gäller handhygien, smycken, klädsel och hår. Data-insamlingen skedde med hjälp av en enkät som delades ut på en klinik. Resultatet analyserades sedan kvantitativt och visade att compliance var hög över lag men att den på vissa punkter behövde förbättras.

Dans som utställningsobjekt : Upplevelser och erfarenheter av tid och rörele i Dansmuseets permanenta utställning

This essay concerns dance as an exhibition object by examining the permanent exhibition at The Museum of Dance in Stockholm, Dansmuseet. Due to its dependence on the temporality and movement of the lived body, dance does not easily lend itself to being exhibited in a traditional exhibition display; and since the live dance performance itself is ostensibly absent at the exhibition display, other means of representation must be relied upon in order to evoke the exhibition visitors? experiences of time and movement as well as the feeling of dance. Starting from a phenomenological first-person perspective, as an exhibition visitor, I present three ways in which such experiences may come about. The cross-section of the experience evoked and the means that trigger them are intermedial, spatial, and performative taking their departure in the visitor?s pre-understanding of dance..

The Determinants and Impacts of Executive Stock Options

The thesis main objective is to establish the determinants for granting executive stock options and to examine their impact on performance for firms listed on OMXS30. The analysis is based on accounting data gathered from annual reports and Thomson Datastream. The empirical results display that firms grant stock options to mitigate the principal-agent problem. Furthermore, risk proves to be positively significant with executive stock options, implying that either executives increase the level of risk after being granted stock options or influence the decision of the remuneration towards stock options when the firm increase the level of risk, in purpose to boost the expected value of their options. No relation between executive stock options and firm performance could be established..

Utmattningssyndrom och KASAM. En möjlighet till en ökad känsla av sammanhang?

Some people who recovered from exhaustion disorder report that their lives feel more meaningful after the disease than before, despite residual symptoms and difficulties. This experience of increased meaningfulness has been linked to sense of coherence, SOC. The research question was whether individuals with exhaustion disorder at onset has a weak SOC, and if there is a general increase towards a higher SOC value ??during the recovery process. In a cross-sectional study, data were gathered on the SOC value via the SOC 29 form.

Den nya svenska kroppen

Detta examensarbete är en undersökning i kommunikation genom konst och design.Det är ett gränsöverskridande samarbetsprojekt vars syfte är att skapa en diskussion kring ett fortfarande tabubelagt ämne. Genom ett gestaltande arbete i textila material undersöks hur vi på ett kreativt sätt kan bidra till samhällsdebatten runt övervikt och fetma. Projektet resulterade i två textila verk som gestaltar den nya svenska kroppen. En textil skulptur i form av en överviktig dalahäst och en folkdräkt för den nya svenska kroppen. I vår gestaltning använder vi oss av dalahästen och folkdräkten som symboler för svensken.

Kvalitativ analys av Holmen Skogs internprissättningsmodell :

Transfer pricing has attracted considerable interest among tax authorities in recent years. One of the reasons for this is that various countries have now begun to protect their own tax bases to a greater extent than they did in the past. Sweden has introduced a law on the documentation on the grounds that the tax office to review the pricing of transactions that occur within multinational corporations. The purpose of the law is that companies should apply a transfer pricing that meet arm's length principle, which means that internal pricing reflects market prices. The EU Commission has, together with the EU member states formed a Forum, the EU Joint Transfer Pricing Forum (JTPF), since cross-border trade within groups constitute a threat to the internal market. The Forum has drawn up a code of conduct which includes a model of documentation.

Kapitalstruktur och immateriella tillgångar: en studie av
svenska börsnoterade IT-företag

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.

Cross-sectional study of bovine anaplamosis in South-western Uganda : the impact of wildlife-livestock interface

The tick-borne disease bovine anaplasmosis is primarily caused by Anaplasma marginale. A variety of wild animals act as reservoirs for A. marginale, but the understanding of their role in the epidemiology of A. marginale is yet poor. This cross-sectional study was conducted to establish if proximity of wildlife affect the prevalence of bovine anaplasmosis in cattle.
