Bakgrunden till examensarbetet är att det existerar ett behov inom Sandvik Materials Technology att komma tillrätta med problemen avseende dålig leveransprecision och antalet reklamationer genom ett förbättringsprogram som kan angripa alla bekymren inom företaget. Företaget har i dagsläget inlett ett internt förbättringsprogram kallat Lyftet Ledtid, med övergripande syfte att sänka ledtiderna i processerna för att minska kapitalbindningen samt uppnå bättre kvalitet. Andra företag har implementerat förbättringsprogrammet Sex Sigma och en undersökning av dess lämplighet för Sandvik Materials Technology bör ske. Arbetet syftar till att undersöka förbättringsprogrammet Sex Sigmas utrymme inom det interna förbättringsprogrammet Lyftet Ledtid. Det bör även ange hur en eventuell implementering kan ske.

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

Sociala nätverk tar stor plats på Internet genom virtuella communities. Användare har en större möjlighet att nå dem via mobila lösningar och därmed göra dem till mobila communities. Kriterierna som ligger till grund för framgång för virtuella communitiesvill vi applicera på mobila communities. För att undersöka dessa kriterier, och bakomliggande faktorer, har vi valt att titta på ?tidigt bruk? användning av en mobil community, Facebooks mobila portal med hjälp av Technology Acceptance Model (TAM).

Background: Sweden is a country where vitamin D deficiency seems to be common, partly because of its geographical position, which reduces the availability of UVB radiation, but also that people avoid sunlight due to increased skin cancer risk. Research shows that vitamin D plays an important role in the prevention of many diseases such as cancer as well as autoimmune and neuropsychiatric diseases.Vitamin D is a fat soluble pre-hormone and a collective name for closely related compounds which act as hormones after undergoing a transformation in the body.Humans can utilize vitamin D through diet and produce it in the body by exposing the skin to the sun. Previous observational studies and epidemiological studies have established a hypothesis that there seems to be an association between vitamin D supplementation and reduction of depressive symptoms.Objective: The aim of this study was to investigate if vitamin D supplements may decrease depressive symptoms.Methods: This work is organized as a literature review and article search is made in the database PubMed in January 2012. Keywords used were ?vitamin D and depression? and inclusion criteria were: randomized clinical trials, be conducted on humans, written in English.

Purpose: The purpose of this thesis is to give a contribution to the studies of what strategies those are of importance for challengers in consumer technological markets aiming for the market leader position. To be able to investigate this phenomenon we have chosen to study Microsoft?s second position in the video game console industry. In addition, we want to illuminate Microsoft?s competitive advantages, how Microsoft can take advantage from Sony?s setbacks and what strategies those are of importance for Microsoft in the battle of becoming the market leader.

The purpose of this thesis is to study the relationship between the definition and bibliographical classification of a certain academic subject; social anthropology. The theoretical framework consists of views held in Information Science regarding the definition and classification of subjects. The methodological onset is based on hermeneutical concepts that allow an extended analysis of abstract structures of thought. This analysis comprises of two parts; a descriptive analysis and a comparative analysis. The result of the descriptive analysis, whose aim is to describe the academic subject social anthropology, shows that this is not easy to define, instead it is nowadays almost the same as cultural anthropology.

In this thesis I have chosen to study the use of crowdsourcing in Swedish archival institutions as well as the influence this methodic platform has on the work of modern archivists. This also raises the question whether the nature of the platform is in any way influenced by the attitude working professionals might have towards crowdsourcing as a legitimed working method. This investigation is based on case studies and interviews with archivists from select Swedish institutions and also the methodology of two now ongoing crowdsourcing projects.The theoretical framework on which this composition is based comes from the work of Gregory Asmolov and his work on crowdsourcing platforms and their functionality as tools of governing. Cultural-Historical Activity Theory (CHAT) is applied to analyze how the method of crowdsourcing is utilised by archival institutions and influenced by their daily routine in conjunction with Governmentality as the chosen way of studying how these platforms might control their users.From the results of the performed case studies, two discourses emerged based on the view on quality concerning gathered information amongst the involved subjects. The first of these discourses places it´s trust and faith in users themselves where validity is of a lesser concern than the actual availability of information through the concept of ?wisdom of the crowds?.

This paper aims to examine whether there are any substantial differences between a generation of users born during the 1960?s and younger generation born during the 1990?s regarding the use of digital technologies connected to the Internet. Based on Marc Prensky?s theories on people born before and after 1980 saying those born before are not as natural when it comes to using digital technologies. We used diaries as a qualitative method to gather data from 16 respondents.

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

What drove me to write this paper is the will to  examine if there is a philosophically and scientifically viable  alternative foundation for an objective morality other than what we like to refer to as "God". The  American philosopher and neuroscientist Sam Harris presents in his book The Moral Landscape a thesis for an objective morality based on science in which he states that  science can determine human values. The purpose of this paper is to perform a theoretical trial of The Moral Landscape, examining Harris' thesis and it's relations to the philosophical obstacles that stands in its way, these being mainly the famous philosophical principle "Hume's Law" and G.E. Moore's "Naturalistic Fallacy and Open Question Argument" and thus will serve as my main theoretical foundation. The results of my study was not conclusive since Harris in fact doesn't succeed in bridging the gap between facts and values on a scientific ground.

The main purpose of this examination paper has been to do a review of recent scientific and evaluated studies performed on children 0-15 years of age, treated with an animal as an assistant to the therapist/professional. The key term is Animal Assisted Therapy (AAT). Our focus has been to describe in what fields these kinds of studies have been performed, what the results are and how effective they have been. As a supplement to our study we have performed 8 short telephone interviews with professionals in the same field of occupation corresponding to the studies we have summarized. Our results concerning the studies show that there has been a positive outcome in the treatment of children and adolescents and AAT.

The purpose of this study is to examine modern constructions of Jane Austens work in films and in books on history of literature. The theoretical framework contains sociology of literature, cultural studies and film theory. I compared Jane Austens books Emma, Pride and prejudice and Sense and sensibility with three film versions from recent years. In the books on history of literature I studied, I found three different attitudes towards history of literature, which also influenced the interpretation of Austens novels. The stories in Austens books and in the films are similar.

The aim of this thesis is to examine the characteristics of film cataloguing, and to compare general as in library use and specific as in archival use cataloguing rules. Most rules, both in archives and libraries, use the book as a point of reference. This is somewhat unfortunate on account of the great difference between books and films. The method used is studies of literature and qualitative interviews with three persons whose professional duties include cataloguing of films. The sets of rules which are studied are Katalogiseringsregler för svenska bibliotek KRS and The FIAF Cataloguing Rules for Film Archives.

Under hösten 1997 och våren/hösten1998 har ett pilotprojekt bedrivits i Linköpings kommun. Det är drivet av Kungliga Vetenskapsakademien och Kungliga Ingenjörsakademien och handlar om ett amerikanskt undervisningsmaterial inom naturvetenskap och teknik. På engelska heter det"Science and Technology for Children"vilket givit namnet STC. Det är ett temaarbete med 24 olika teman att använda under de 6 första skolåren.För att använda materialet i skolan har vissa utvalda delar översatts till svenska. Det är endast en direktöversättning och inget speciellt anpassat till den svenska skolan.

Current technology offers many possibilities for remotecommunication. Nevertheless, people with cognitive and communicativedisabilities have limited access to common communication technology like textmessaging via a mobile phone. This study is part of the project Text messagingwith picture symbols - a possibility for AAC users and people with cognitiveimpairments. Semi structured interviews were used to investigate three menand four women?s experiences of using Windows mobiles with adaptedfunctions for text messaging.
