High Precision Positioning and Very Low Velocity Control of a Permanent Magnet Synchronous Motor
The purpose of this report is to evaluate a direct driven permanent magnet motor in high accuracy position and low speed operation. Actuation in this case is usually accomplished by stepping motors combined with belts and pulleys. High accuracy positioning is considered to be within 0.1 degrees and low speed 0.05 degrees per second, while at the same time have a 180 degree step response within 0.5

M-commerce - A small part of E-commerce or something bigger?
Both e-commerce and m-commerce has had and have a big impact on how business today is operated. Furthermore, e-commerce is responsible for creation of many new jobs and its role to the overall economy in Europe is becoming increasingly important. E-commerce is a big part of retail and commerce and is constantly growing. However it is maybe not equally well known that the latest year mobile commerc
Bly i jord och växter: Tillväxt och blyupptag
Jord i anslutning till skjutbanor innehåller ofta mycket höga blyhalter. Blyföroreningarna medför ett ökat upptag av bly i de växter som växer i jord från skjutbanor. Matväxter från skjutbanor kan kraftigt överskrida gränsvärdena för bly i livsmedel. För växterna medför blyexponeringen en omfördelning av biomassa, från rötter till skott. Bly är en tungmetall, och är giftig för såväl växter som djThis study investigates how lead content and bioavailability in soil affects growth and root/shoot ratio in three commonly cultivated species: wheat (Triticum turgidum), clover (Trifolium) and radish (Raphanus sativus). The study investigates the levels at which soil lead content contribute to toxic effects in plants, and when it may pose a risk to consumers. In addition, lead accumulation and the
ADHD i ett familjesammanhang - föräldrars perspektiv på orsaker och behandling
Mot bakgrund av rådande kunskapsparadigm inom barnpsykiatrin samt förändringar i samhällets syn på barns psykiska hälsa avsåg studien att undersöka föräldrars syn på orsaker till ADHD och om denna kunde kopplas till behandlingsönskemål. Avsikten var att utröna om det fanns ett behov av behandlingsinsatser som adresserade mer än barnets ADHD-problematik. Studien genomfördes som en enkätstudie (N = Given the paradigms which are currently predominant in child and adolescent psychiatry and the changes in the societal view of children’s psychological health, this study examined parental attitudes towards the causes of ADHD and if these were related to choices of treatment. The aim of the study was to determine whether there was a need for treatment which addressed more than just the ADHD sympto

Stormwater management in Gaborone - A study of the quality and quantity of water in Segoditshane River
Återanvändning av regnvatten för att förbättra Gaborones vattensituation Gaborone, liksom större delen av södra Botswana, lider av extrem vattenbrist. Torka och uteblivna regnperioder har gjort att vatten nu måste transporteras långa sträckor för att täcka stadens behov. Den ansträngda vattensituationen talar för att använda alternativa vattenkällor, däribland återanvändning av regnvatten. Den sThis master thesis was partly performed as a field study in Gaborone, the capital city of Botswana, located in southern Africa. The semi-arid climate in Botswana together with a rapid financial development in the country during the last decades has increased the need for water. The last years the water situation has been strained in Gaborone, and Gaborone dam which used to be one of the city’s dri

Basophil Signaling in the Endocrine Pancreas - Implications of beta cell dysfunction/destruction in Diabetes Mellitus
Diabetes Mellitus is a generic term for metabolic diseases were insulin levels are insufficient and in type 2 Diabetes Mellitus insulin also fails to stimulate glucose uptake. Recent findings indicate that cells from the innate immune system could be involved in development of both type 1 and type 2 Diabetes Mellitus. Basophilic granulocytes are part of the innate immune system and contribute to h
Hemliga tvångsmedel i it-samhället: Hemlig avlyssning och övervakning av elektronisk kommunikation
Området för hemlig avlyssning av elektronisk kommunikation (hemlig teleavlyssning) och hemlig övervakning av elektronisk kommunikation (hemlig teleövervakning) är ett område som tidvis vållar stor debatt bland jurister och även bland allmänheten. få EU-rättsliga akter har nog varit så medialt uppmärksammade som datalagringsdirektivet som nyligen ogiltigförklarades av Europeiska unionens domstol. DThe area of covert interception of electronic communication (telephone tapping) and covert surveillance of electronic communication (covert telephone surveillance or metering) is an area which at times causes much debate in the legal profession and among the general public as well. There are probably few legal acts of the European Union that have received as much attention in the media as the Data

Elevers upplevelse av ljudmiljön i grundskolan – en enkätstudie
Bakgrund: Den här studien undersöker elevers upplevelse av ljudmiljön i grundskolan. Forskning visar att dålig ljudmiljö försämrar bland annat taluppfattning och arbetsminne. Man har sett att barn påverkas i större utsträckning än vuxna men det finns få studier som undersöker hur de själva upplever ljudmiljön. En enkät utvecklades 2013 i England för att undersöka detta. Syftet med denna studie är
