Till en älskad vän : materia och objekt som medier för överföring

With self-hypnosis as a method, I work with levels of consciousness in relation to practice. Focus lies in the relation between a language of materials and an inner experience. How do material expressions function as mediums of a spiritual matter between a beholder and me? The trance functions as a space for a spiritual contact/communication. Abstract images of crystalline glaze on ceramic tiles are direct results of these acts.

Samspelet mellan IT-avdelning och verksamhet : En studie av hur koordination påverkas av strukturer och social interaktion

Several surveys indicate that corporate leaders still consider the aligning of IT and business functions as a top management issue. The aim of this thesis is to illustrate how coordination emerges between IT and business departments and how formal structures intended to coordinate are influenced by human action. To deepen the understanding of this phenomenon we seek to analyze IT/business coordination from a perspective based on practice theory. A field study was conducted where observations and informal interviews were carried out at the IT department of a global company. The empirical analysis indicate that coordination problems between IT and business departments is in part affected by embedded factors such as different goals and perspectives on how IT is to be used in the organization or how to design IT related processes.

Trådlös kommunikation för Anybus

The industry struggles with problems concerning physical damage to wiresand communication in remote areas. Introducing a wireless network canprovide a solution to these issues.

ARM i inbyggt system - med prototyp

Inbyggda system blir allt vanligare i dagens samhälle. De inbyggda systemen finns i nästan allt nuförtiden, från diverse fordon till leksaker för barn.Dagens teknik innebär bland annat att gårdagens lösningar kan realiseras på en bråkdel av den tidigare ytan. Allt mer blir ytmonterat med mindre och mer komplexa kretsar. Detta är inte alltid till utvecklarnas fördel då montering av prototypkort blir en svår och/eller dyr process.Målet är att ta fram ett inbyggt system med en ARM-processor. Systemet ska innehålla USB-OTG, ethernet, minne av olika slag som FRAM och microSD samt en display med pekskärm för användargränssnitt.

Al-Jazeera och CNN - En jämförande fallstudie i krigsjournalistik

Författare: Magnus Gustafsson Niclas HagelHandledare: Thomas KnollExaminator: Martin DanielssonTitel: Al-Jazeera och CNN - En jämförande fallstudie i krigsjournalistikTyp av rapport: C - uppsatsÄmne: Medie- och KommunikationsvetenskapÅr: Höstterminen 2008Sektion: Sektionen för Hälsa och SamhälleSyfte: Vårt syfte är att studera och jämföra al-Jazeeras och CNN:sbevakning av en händelse i Afghanistankonflikten för att kunnaredogöra för eventuella skillnader. Vi vill se hur olika faktorerpåverkar journalistiken. En analys ur ett genusperspektivkommer också att göras.Metod: Fallstudie har tillämpats som huvudsaklig metod och vid analysav material har innehållsanalys och kritisk diskursanalys använts.Slutsatser: Efter att ha jämfört de två nyhetskanalerna kan vi tydligt se attdet finns stora skillnader i rapporteringen av ett amerikansktflyganfall mot en afghansk by. CNN som amerikansknyhetskanal visar att deras rapportering påverkas av detamerikanska medieklimatet där en neutral krigsrapportering kanses som stötande och journalister ständigt utsätts förpåtryckningar. Ur ett genusperspektiv ser vi dock tydligalikheter mellan kanalerna..

Service i privat sektor ? En kvalitativ studie om servicearbetarens upplevelse av sitt jobb

The aim of this qualitative study of service work in the private sector is to examine how the service worker experiences his/her work. There are three dimensions of the service workers experience in focus, and they are the base of my formulation of questions. The first dimension refers to how the service worker experiences the emotional labor demands from the employer. The second dimension concerns the relation between service worker and customer, from the view of the service worker. The third dimension problematizes how service workers experience efficiency.I have interviewed three call center customer workers and two hotel receptionists, using semi-structured interview technique.

Fallstudie för distribuerad installation av operativsystem

Rapporten undersöker om det är möjligt att använda Clonezilla för distribuerad installation av Windows Vista som alternativ till Symantec Ghost. Ett ytterligare krav är att installationen ska vara automatiserad och inte kräva något extra arbete efter installationens slut. Dessutom ska datorerna vara redo att användas i en Windows-domän efter en färdig installation.Programmet Clonezilla är av typen open source och är fritt att använda medan Symantec Ghost är en kommersiell produkt som kräver flertalet licenser beroende på antalet datorer. Clonezilla körs i Linux och saknar grafiskt gränssnitt, Symantec däremot har ett eget gränssnitt för att överskådligt hantera datorer och distribuera operativsystem i välkänd Windows-miljö. Båda lösningarna testas under flera praktiska experiment i labbmiljö.

Co-Creation - Synsätt inom marknadsföringslitteraturen

The creation of value is considered the core purpose and central process of economic exchange. Value creation is now conceptualized as shared by both producers and customers, and value is seen as fundamentally derived and determined in use, the integration and application of resources in a specific context, rather than in exchange, embedded in products and manifested as price. The field of research is abundant with publications but these do not fully further the understanding of value creation and co-creation in a way that is meaningful for theoretical development and decision making in business and marketing practise. Without a thorough understanding of the factors characterising value co-creation, the nature as well as content and locus of co-creation cannot be identified. In that case value co-creation easily becomes a concept without substance. Until now, individual publications on co-creation have focused on few or different aspects, have emphasized the process from either the customer?s or from  the firm?s vantage point, have different theoretical approaches and have ignored the complexity in interactions between actors.The purpose of this essay is to analyse how five fundamental aspects of co-creation of customer value are perceived in contemporary marketing literature. Discussing the different views on co-creation, this essay concludes that thoughthere are evident points of agreement, finding one generally valid doctrine of predestination or value co-creation is improbable.

Deltagarnas utställning : Utställningarana Hej! och Present i teori och praktik

Many institutions currently work with visitor participation. Participatory culture is basically to invite visitors to participate and to give an opportunity to co-creation. In my research I have studied two projects. The first one is the exhibition Hej! produced by Postmuseum (the Swedish mail museum) and the second one is Present by Riksutställningar (a Swedish government).This development indicates that the museums are on their way towards a new definition. Earlier museums were defined as a source of knowledge which purpose was to spread lore to the people.

Karakterisering av bioslam för modellering av biogasproduktion

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Det individuella samlandet : från längtan till begär

This essay deals with the individual collecting of four individuals with different backgrounds and lives. The essay investigates what, how and why people collect. It provides a stepping-stone in moving closer to understanding one, in human nature, deeply rooted phenomenon - collecting.The essay is based on a list of questions made by the Nordic Museum in Stockholm. It also includes in-depth examinations of four person?s passion of collecting, in which four individuals were interviewed: a pig collector, a collector of Mickey Mouse items, a multi-collector of objects from other cultures and one collector of items related to the artist Madonna.

Arkitekturer i operativsystem : en fallstudie i monolitisk och micro kernel

Den tekniska utvecklingen driver fram allt mer avancerade datorsystem. Samtidigt ställs allt större krav på stabilitet och flexibilitet i de operativsystem som ska användas på dessa system. De senaste årtiondena har micro kernel arkitekturen varit föremål för intensiv forskning och det finns idag ett flertal operativsystem på marknaden som använder denna arkitektur. Traditionella monolitiska operativsystem är relativt resurskrävande system som ofta anklagats för att sakna struktur. Micro kernel baserade system är en lösning på detta problem där man bantat ner kernel till så lite som ett tiotal kilobyte och flyttar ut tjänster som normalt ligger i kernel till user space.

BitTorrent i kommersiella system : Identifiering av incitament och användarbeteenden

Companies that sell digital products such as software and movies transfer large amounts of data to its customers. In order to send this amount of data using FTP or HTTP and still maintain a high speed transfer rate it is required that the company have a large number of servers and a huge bandwidth. Servers and bandwidth costs money which means they have great costs on the distribution of their products. In order to reduce distribution costs, P2P technology can be used and the most powerful technology to transmit popular files is called BitTorrent.BitTorrent requires users to share their bandwidth. Nowadays, BitTorrent is frequently used to transfer products that are free of charge; one example is the Linux distribution Ubuntu.
