The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Harmoniseringen av bolagsbeskattningen inom EU har länge gått långsamt. Trots att eta-bleringsfriheten i artiklarna 43 och 48 i EG-fördraget stadgar att företag har rätt att startaoch driva verksamhet i andra medlemsstater finns det fortfarande skattemässiga hinder som avskräcker från sådana etableringar. Endast ett fåtal direktiv har utfärdats inom bolagsbeskattningen för att underlätta för företag på den inre marknaden. Anledningen till avsaknaden av reglering är att artikel 94 i EG-fördraget föreskriver att rådet måste vara enigt vid utfärdandet av direktiv inom direkt skatt i vilket bolagsbeskattning inkluderas. Eftersom det saknas tillräcklig reglering har EG-domstolen kommit att spela en roll i harmoniseringsarbetet.

Studiens övergripande syfte har varit att i en jämförelsestudie undersöka hur barns lek på tre olika skolgårdar skiljer sig åt och om det finns ett samband mellan de olika skolgårdarnas utformning och barns lekar. Undersökningen är baserad på observationer och enkätformulär som har använts för att samla in data som är såväl kvalitativa som kvantitativa. Undersökningen avgränsades till tre närliggande skolgårdar med olika utformning. Barnen som deltog i enkätundersökningen gick i årskurs tre. Vid observationstillfällena ingick barn från årskurs ett till tre.Resultatet visar att oberoende av skolgårdens utformning så är rasterna populära och att barnen leker oberoende av dess utseende och funktion.

Funktionskraven på industrigolv har under senare år ökat. Ett industrigolv skall klara att överföra laster till underlaget samt utgöra ett fast och plant underlag. I denna rapport har två utföranden av påldäck för golv i lagerlokaler jämförts. Den traditionella metoden med armeringsnät har jämförts med en något nyare metod med stålfiberarmerad betong. Jämförelserna har gjorts under förutsättning att golvet skall belastas med 3 ton per kvadratmeter.

Syftet med uppsatsen var att undersöka Pantrarna genom att se på vad för typ av social rörelse Pantrarna är. Sociala faktorer som låg bakom bildandet, deras förebilder, metoderna de använde, hur de organiserade sig och vad de ville uppnå undersöktes. Bakgrunden till bildandet av en social rörelse som Pantrarna var komplex och flera teorier och begrepp fick därför användas för att försöka förklara kontext såväl som Pantrarna som social rörelse. Uppsatsen är gjord genom en kvalitativ metod bestående av intervjuer, innehållsanalys på filmen om dem, observation vid deras festival, netnografisk studie av rörelsen där Facebook,Youtube och deras hemsida studerats. De viktigaste resultatet som hittades var att Pantrarna är en social rörelse som bygger på ett konfliktperspektiv där de använder metoder som att storma politikers möten och genom demonstrationer.

 Today a major part of the energy produced steams from fossil fuels, finite resources, and a change towards an energy sector based on renewable energy is necessary. Sweden is one of the leading countries with regards to investments in renewable energy but most other countries have a long way to go. This makes it interesting in developing renewable energy projects in new markets in countries like Poland where still a lot of fossil fuel is used. Large infrastructure development projects are very costly and therefore external investors needs to be involved. The investors play an important role in changing the usage of fossil fuels towards renewable energy sources.

Modedieter är någonting som kommer och går i Sverige och den senaste populärdieten är 5:2-dieten. Syftet med studien är att undersöka och få en ökad förståelse om 5:2-dieten och dess utövare. Studien är baserad på en tvärsnittsdesign och som metod har en enkätundersökning utförts. Studiedeltagarna som deltog i enkäten är 150 personer varav 121 är kvinnor. Deltagarna i undersökningen hade utövat dieten olika länge, alltifrån 3 veckor upp till mer än 6 månader.

This thesis examines source criticism and critical thinking among upper secondary school students in social science in three different schools in Sweden. Our particular focus lies in investigating the student's critical thinking skills and evaluation of digital sources when they work independently with different projects. How do students value and sort the information they find? We looked furthermore at what factors that may influence students in their evaluation of sources. Moreover, the purpose of this thesis to investigate how the student's critical thinking skills can be used as tools to become more information literate in a learning context.

In Eskilstuna and Sweden in general the level of reuse of surplus material containing soils and rocks from excavation is low. In this report the potential for increasing the reuse of excavated material in Eskilstuna by using a web-based earth information database has been examined. The purpose of a web-based earth information database is to connect those who have surplus material with those who need material for a fast and simple transaction. The intention is to give Eskilstuna a more environmentally and economically efficient handling of surplus material by increasing the level of reuse and thereby reducing the amount of surplus material that is wasted and emissions given off to the atmosphere during transportation. The potential has been examined in two different ways, by tracing information about a number of projects to see if excavated material driven to the dump could have been used in another project and by interviewing eight of the work leaders active in Eskilstuna.

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.
