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).

In this investigation has an attempt to find out whether so called transplanting shock depends on the moving and transplanting of trees, to other conditions, or if it is due to the imbalance between the root to shoot ratio. Seventy trees of Prunus avium have been part of the investigation and these trees have been divided into four different groups depending on methods of production, untouched on the field, trees still on the field but with root pruning, trees moved and planted into Root-Control-Bag, trees moved and planted into Spring-rings. To be able to answer the question, measurements of the length of the terminal shoots and the lateral shoots and the dimension of the stem growth have been done and also has a visual judgment of the trees vitality been performed. The result shows that it is not only the move of the trees that gives them transplanting shock, but rather the loss of roots which gives an imbalance between the root and crown..

Globalization has stimulated the free markets and has made possible for Swedish companiesto expand internationally. Some markets have been deemed attractive and companies havechosen to enter them. The decisions concerning internationalization and marketing havedetermined the success of the companies on the new market. Therefore, several elementsbecome important: the motives behind the new market entry, the local marketcharacteristics and the adaptation of the four components of the marketing mix ? product,price, place and promotion.The purpose of this thesis is to study how three Swedish companies adapt their marketingmix to the local conditions in Australia and identifies success factors in order to help othercompanies considering a market entry.

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

Marknadens reaktion när ett företag informerar och annonserar om en eventuell nyemission sägs vara oförutsägbar. Enligt tidigare forskning pressas aktiekursen i de flesta fallen nedåt vid en nyemission. Under det senaste året har en del nyemissioner utförts i synnerhet på grund av den globala lågkonjunkturen då många företag haft för lite kapitalbas. Vad gäller företag på Stockholmsbörsen som valt att nyemittera aktier har även här de flesta fått se sin aktiekurs rasa.Författarna till denna uppsats avser att studera hur marknaden reagerar på ett offentligt tillkännagivande av en kommande nyemission. Det undersöks även om det förefaller någon skillnad mellan tillkännagivanden av nyemissioner genomförda innan eller under lågkonjunkturen och skillnader branscher emellan.Då vi ville se hur denna händelse påverkar ett företags aktiekurser valde vi att göra en eventstudie.

Börsnoterade bolag i spelbranschen med pokerklienter har det senaste året haft kraftigt stigande aktiekurser. Vår uppsats ämnar undersöka om dessa företag är övervärderade på grund av det stora ökade intresset för poker. Vi har genomfört analyser med hjälp av target price och multipelvärdering. Vi har förklarat hur regressioner på dessa bolagen ser ut samt koncentrerat oss ytterligare på vad som driver Unibets aktiekurs. Det resultat vi har kommit fram till är att branschen i sin helhet inte är övervärderad utan snarare korrekt prissatt, med reservation för eventuell undervärdering.

In southern Sweden, beech (Fagus silvatica) and spruce (Picea abies) are two species with similar demands on soil properties. With increased global warming and high acid deposition the future may bring larger areas were the two species are overlapping, competing for the same soil. The aim of this study was to compare spruce and beech concerning distribution, cultivation and soil properties. From available data comparisons were made between spruce and beech forests in Sweden. Soil analyses were made on samples from beech forest in southern Sweden, with and without natural regeneration of spruce.

There are various value-influencing factors that have various effects on the value of a cooperative flat for buyers. What generates value is individual and different from buyer to buyer, but also between buyers and real-estate agents. Consequently, the real-estate agents who perform valuations can make incorrect estimates of a residential value. Therefore, it is important to examine which factors are important for buyers to prevent incorrect valuations. To find out which these factors are and which of them that are the most important for potential buyers, previous research has been done in larger cities in both Sweden and other countries.

The purpose of this study is to evaluate the real aggregated consumption and empirically determine its exogenous variables. A multiplicative analysis is done in the context of government stabilization policy to find out how policymakers can execute a stimulus package that will bring the best multiplicative effect to the economy The conclusion of the study is that real income, net financial assets and real-estate price index are all statistically significant. An effective expansive fiscal policy is a public-financed investment in the private sector. Coordination is going to be crucial when stimulus package is developed due to the fact that leakage in the form of imports will prevent the expected multiplicative effect..

Title: A study about the purchasing process of ITLevel: Master thesis in Information Technology and Business Administration, 15 hp, EIK024Authors: Emelie Johanson and Mikael LindströmTutor: Peter Ekman, Mälardalens HögskolaKeywords: IT-investment, purchase, decisionProblem: In the last decades the amount of IT investments increased and has become an important resource within most organizations. IT gives the ability to compete and could also be a condition for many to be able to compete. In different businesses it could vary in where they put their focus when they choose an IT investment. This thesis examines how the purchase process of IT looks. How does processes differs in a bigger company versus a smaller company? From these two perspectives this study examined these research questions: Who makes the decisions whether or not an IT solution should be purchased? What aspects decide when companies are to choose between different IT solutions? Where in the purchase process do problems usually emerge?Purpose: The purpose of this thesis is to describe and analyze the purchasing process of IT from a business perspective.

?Det finns en chans att man hittar ett unikt plagg som ingen annan har.?(Kommentar från undersökningen)Idag används second hand kläder flitigt av trendsättare och kändisar och är ofta ett återkommande tema i modetidningar och styling jobb. Kända personer som skådespelerskan Josephine Bornebusch och artisten Agnes Carlsson förespråkar second hand och har alla second hand- kläder i sina garderober. Två detaljhandelsföretag som är välkända inom second hand- branschen är företagen Myrorna och Beyond Retro. Trots att de är verksamma inom samma bransch, andrahandskläder, har de enligt oss fokuserat på olika element som gör dem konkurrenskraftiga.
