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).

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.

Syftet med detta examensarbete är att undersöka hur förskollärare ser på arbetet med musik i förskolan, vilket syfte de har med musikstunderna och på vilket sätt barnen ges inflytande över hur musikstunderna utformas och får möjlighet att använda sin kreativitet. Studien genomfördes med hjälp av kvalitativa intervjuer med fyra förskollärare och den teoretiska bakgrunden utgår från ett sociokulturellt perspektiv.Musikstunderna på förskolor är vanligtvis spontana och initieras av både vuxna och barn. Förskollärarna är positivt inställda till musik men det förekommer en osäkerhet om den egna kompetensen inom ämnet. Musiken fungerar ofta som ett medel för att lära sig något annat, och inte som ett mål i sig. Förskollärarna upplever att barnen ges möjlighet till inflytande i musikstunderna och att barnen har tillgång till material av olika slag, som exempelvis instrument.

Entrepreneurship is said to be the missing link between knowledge and growth in the Swedish economy. New ventures run a high risk of failing and this holds true especially for technology ventures. Since company leaders have proven to exert an influence on organisations' survival possibilities, the selection of an appropriate CEO is important. The purpose of this study is to describe the importance of the CEO for ventures as well as to explain how knowledge and experience affect the opinion of who should be CEO. Using a qualitative case study research design including three life science companies, we show that there are three main factors crucial when selecting a CEO.

Most companies and organizations today depend on technology connected to the Internet. Schools and offices have therefore been providing computers, phones and other technology to the employees. The recent technological development and decline in prices for technology have contributed to making these products a part of everyday life for most people. This has made it very common for employees and students to bring their own devices into school and workplaces.The aim of this study is to define what "Bring your own device" means for Swedish companies and organizations and how it has been implemented in those. The aim is not mainly to generalize to all Swedish companies but create an understanding how the trend is used to provide a basis for continued research in this area.

Title: Creating meetings - a study in interactionism and creating music. In this study I had my focus on teenagers in a school class. My aim was to explore how pupils experience the processes of creating music together and how they choose to organize their interactions during these creative processes. As analytical tools I used sociological and sociopedagogical concepts and theories. Interactionism provided models toward individualization as well as socialization, related to learning, knowledge and creativity.

I denna uppsats syftar jag till att undersöka hur, när och på vilka sätt samlärande kan ske imusikundervisning. Genom observationer och intervjuer på barn undersöks hur och påvilket sätt barn lär av varandra på musiklektioner. Med samlärande menas allt lärandesom sker mellan människor och begreppet utgår ifrån hur vi i en lärprocess kanförespråka delaktighet, kommunikation och mångfald av idéer och tankar. Vygotskij ochPiaget har haft stor inverkan på samarbetes roll i våra läroplaner och det framgår främstgenom ett demokratiperspektiv på undervisningen. Dock tycks betydelsen av barnssamverkan i läroplanerna minskat genom åren.

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.

Distributed system development is a common occurrence in today?s technological and global world. Because the consequences of its geographically distributed nature it creates barriers between people that affects their communication and collaboration efforts in the distributed context. Despite a lot of technological breakthroughs over the last decades and the occurrence of video-conference applications and other tools for communication and collaboration, cultural and geographical issues have so far not yet been completely resolved. In this study I have made a literature study over distributed system development to form a set of central factors that affects the distributed development process.

This study examines how to translate digitally composed symphonic music to note script and how it gets readable and playable. With the help of professional musicians from the Norrköping Symphony Orchestra, teachers from Kulturskolan in Norrköping as well as other musicians, I have learned how I can improve each individual stem in my composition. I also learned how to write for a real musician. My score have been analyzed by composers and a conductor which have given me a more in depth insight into composing symphonic music.The theory section describes important MIDI aspects, score preparation and note editing techniques. Thereafter is a section about the symphony orchestra and its instruments? history and how the situation is today.
