ADS och Matlab för optimering av pre-distortion av effektförstärkare

This master?s thesis deals with integrating simulations using Agilents Electronic Design Automation tool ADS with customized Matlab scripts, for solving complex analog and digital radio architectures. In particular, it addresses predistortion, realized in the digital domain, of power amplifiers, modeled in the analog domain. The former is implemented in Matlab while the latter is implemented in ADS. Two versions of integrating the two systems have been tested: 1) Iterative approach on sample basis and 2) Scheduled batch solution by matrix inversion.

Social E-handel?: - Hur närvaro av andra besökare påverkar utvärderingen av en webbsida

Internet - and the website - has developed into an essential key for the relationship between enterprises and its customers. Today, a website might be the first or only impression a customer gets of a company. With this in mind we have focused our study on customer evaluations on websites. Social presence and its impact on people have so far mostly been given attention in the research of behavior in physical environments. However, in the electronic marketplace this has so far been overlooked, which is why our aim is to study how the presence of visitors impacts other visitors on the same website.

Termisk analys av kompakta jordvärmesystem - Sensitivitetsanalys och korrektions faktorer baserat på fältmätningar i referensanläggningar i Östergötland

Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.

Den svenska åldersstrukturens påverkan på den ekonomiska tillväxten

Hur åldersstrukturen i ett land påverkar den ekonomiska tillväxten i Sverige är en aktuell fråga, då den svenska befolkningen håller på att bli allt äldre. Det kommer att påverka ekonomin på flera sätt. Uppsatsen syftar till att undersöka hur förändringar i den svenska åldersstrukturen har påverkat den ekonomiska tillväxten i Sverige, samt försöka ge en fingervisning om hur de framtida förändringarna kommer att påverka den ekonomiska tillväxten. En regressionsanalys med förklarande demografiska variabler genomförs för att utreda hur den svenska åldersstrukturen har påverkat den svenska ekonomiska tillväxten. Regressionsanalysen är gjord efter inspiration av en Solow-modell som har utvecklats med demografiska variabler.Resultatet visar att olika åldersgrupper påverkar den ekonomiska tillväxten på skilda vis.

Skapandet av ett integrerat ledningssystem

To be able to compete on the market environmental Management System has become an important part of operations work. However, many companies still haven?t implemented an environmental management systems due to lack of time and the high costs. One of the companies with this problem is Falu Bildemontering. Their goal is to accredited according to the ISO 14 001 certificate.

Bremsningens effekter hos häst : utvärderat med hjälp av termografi, hormonanalyser och hematologi

Twitching is frequently used in horse management because of its sedating and pain-relieving effects. In this study, the effects on the horse?s nervous system by twitching were investigated by thermography of the skin temperature. The temperature is regulated by the sympathetic nervous system through postganglionic sfincters at the capillaries of the skin. The effects on the endocrine activity have also been studied by the measuring of ACTH and cortisol in blood plasma.

Det svenska konsumtionsbeteendet-En ekonometrisk analys av den permanenta inkomsthypotesen

Abstract Titel: Det svenska konsumtionsbeteendet ? En ekonometrisk analys av den permanenta inkomsthypotesenTopic/course: NEKK01, Bachelor thesisWriters: Ida Hedlund, Anna Persdotter Supervisor: Fredrik NG Andersson Keywords: Permanent income hypothesis, Milton Friedman, Consumption smoothing, Sweden Purpose: The purpose of this thesis is to examine whether the permanent income hypothesis can be applied on the consumption pattern of Sweden during the time period 1950-2006. Method: To do the observation an econometric regression analysis has been made. The variables tested are consumption, real GDP, stock- and real estate market prices. In the model three different time periods have been investigated to facilitate the origin of different patterns.

Downsizing : Hur överlevare av uppsägningar påverkas av upplevelsen

In today?s business environment, cost-cutting practices such as downsizing and layoffs remains a widespread phenomenon. Although, the understanding of the effects that these practices has on the remaining individuals, defined as the survivors, is poor. The focus in this paper is therefore to examine how survivors of layoffs can be affected on an individual level, and by what causes.The study was conducted using open-ended, qualitative interviews with three individuals with different experiences of layoffs. The empirical data was analyzed by extracting quotations from the interviews.The study found that layoffs affected the morale and attitude towards management of the individual, and that perceived justice and uncertainty are two causes of negative effects from layoffs..

Effects of brown bear (Ursus arctos) odour on the patch choice and behaviour of different ungulate species

The return of large predators to regions where they were previously extirpated has created a need for knowledge about their effect on prey species, not only their lethal but also their behavioural or risk effects. In this study the behavioural risk effects of brown bear (Ursus arctos) were tested on fallow deer (Dama dama), roe deer (Capreolus capreolus), red deer (Cervus elaphus), moose (Alces alces) and wild boar (Sus scrofa). This was done by using patches of fur to simulate the presence of the novel predator (brown bear), a novel nonpredator (reindeer (Rangifer tarandus) and no fur as control. These three treatments were then compared. The response variables measured were increased vigilance, decreased feeding time and change in patch use.

En vindkraftparks inverkan på Gävle Energis elnät

The effects from a planned wind farm on the grid utility Gävle Energis electrical grid have been studied. The wind farm is planned to be built in the forest 15 km north of Gävle and will have 23 turbines with rated power from 2 to 2.5 MW, resulting in a total installed power between 46 MW and 57.5 MW. The grid connection will be made at 70 kV. The aim of the analysis was to determine what effects the wind farm would have on the power grid in the form of electrical disturbances (flicker etc.), need for new investment and raised operational cost. To allow the connection of the wind farm technical solutions (new lines, power stations and grid reinforcements) have been constructed.

Implementeringen av miljöansvarsdirektivet i den svenska rätten : En europarättslig studie om förvaltningsförfarandet vid miljöskador utifrån principerna om god förvaltning och processuell autonomi

The aim of this thesis is to examine how the EU directive 2004/35/EC on environmental liability impacts the Swedish administrative legal order. The thesis examines the directive through two main EU principles - the principle of good administration and the principle of procedural autonomy. The EU principle of good administration as a concept contains various procedural and substantive obligations that make up the subject for examination of the directive, both as regulated in the directive and as general principles of EU law. The directive is analyzed using a comparative method to determine to what extent the procedural and substantive principles of the directive impacts the Swedish administrative law, and weather or not the Swedish regulations comply with the EU principle of good administration.The results of the study shows that, althought there?s a general principle of national procedural autonomy, the EU principles of good administration do affect the Swedish administrative regulation in various aspects, through the implementaion of the directive on environmental liability as well as general principles of EU law.

Samhällsuppbyggnad och demokratisering i Bosnien-Hercegovina : En utvärdering av SIDA:s aktuella verksamheter i Bosnien ur ett fredsperspektiv

SIDA?s relief work in Bosnia aims at making the country ready for a membership in the EU where the main focus lies in the creation of a sustainable state as well as liberalizing the market to create an increased economic cooperation between Bosnia and the rest of Europe. These ambitions are closely related to the neo-liberal theory of state building which aims at creating democratic societies in line with the western democracy model, with a liberal economy constituting its base. Despite generous financial aid, the democratic and economic development in Bosnia is moving very slowly and the ethnical tensions seem to grow despite international involvement in the country. The purpose of this study is to evaluate SIDA?s present relief work in Bosnia out of a peace perspective.

Psykologiska mekanismer och miljöperspektivet : sambandet mellan attityder och beteendeintentioner inför samhällets miljöpåverkan

Syftet med studien var att pröva vilka psykologiska mekanismer som påverkar sambandet mellan attityder och beteendeintentioner inför miljöpåverkan hos individer i konsumtionssamhället. Hypotesen var att det finns ett miljömedvetande hos människan, men att det är en skillnad mellan attityd och beteendeintention. Även emotioner inför miljöpåverkan hos deltagarna undersöktes, för att fördjupa studien. Undersökningen har gjorts kvantitativt via en webbaserad enkät, genom utskick via Facebook till vuxna individer i Sverige mellan 18-65 år (N=49). Svarsprocenten var 46 procent.

Anställdas attityd till miljön och miljöledningssystemet: ALSTOM Power Sweden AB

Today environmental management systems (EMS) are common documents (more correctly, a combination of documents) that direct, steer and regulate environmental efforts within many companies. The intention of EMS is that its guidelines are reflected in how the employee carries out his everyday work tasks. This study aims to illuminate the attitudes that exist regarding the EMS at ALSTOM Power Sweden. By using questionnaires and interviews as a method to communicate with employees,a study of the existing attitudes regarding the EMS was carried out. The results were analyzed categorically and statistically and show that there are consistent attitudes among employees, but that there are also inconsistent attitudes.

Internprissättning : Bevisbörda, dokumentationskrav och rättssäkerhet

As the globalization of companies increases day by day, the need for a clear and comprehensible legislation to overcome the problems with transfer pricing transactions increases as well. Incorrect pricing in transfer pricing situations between companies with close economic ties to each other makes countries risk parts of their taxation income.Swedish legislation uses the internationally accepted arm?s length principle to regulate the transfer pricing transactions. Through the correction rule, the rule is upheld that the pricing between two companies with close economic ties to each other must apply to the same conditions as it would have been if it was between two companies without close economic ties to each other.To ensure that enough material is provided to base the assumption whether or not the correction rule has been followed or not, Swedish legislation provides a number of paragraphs to regulate the matter. The legislation is spread all over and is hard to interpret.
