Reducering av ledtid genom en värdeflödesanalys En fallstudie på Lammhults Möbel AB

The purpose of this study is to increase the understanding of activities, flows and waste in a company's production process. By performing a value stream analysis, non-value adding activities are identified in a production process and then the suggested improvements that can reduce lead times will be stated. The value-stream mapping identifies the flow of information and the flow of material in a production process and this provides the basis for the identification of non-value adding activities.We conducted the study at Lammhults Möbel AB in Lammhult Sweden, where the production flow of Spira-21 has been investigated. This to identify any non-value adding activities that affect the flow negative and consumes time and money in a non-value adding way.A reasonable approach for the project was taken by studying the methodologies and theories. We conducted interviews and site surveys at Lammhults Möbel AB where the flow of information and material in the production process were investigated.

Vad behöver en speldesigner tänka på vid utvecklingen och analys av ett implementationsförslag till ett spelgränssnitt?

Denna reflexiva rapport undersöker processen att utveckla ett implementationsförslag för ett användargränssnitt till ett spel som ska lära ut riskhantering till körskoleelever. Den reflexiva rapporten genomför också en analys av användargränssnittet och innehåller därför en kort genomgång av riktlinjer och gränssnittsprinciper från människa-datorinteraktion (MDI) samt teorin om Flow. Den reflexiva rapporten avslutas med en utvärdering av arbetsprocessen och lärdomar kring arbetet. Slutsatsen som dras är att riktlinjer och principer från MDI samt Flow inte alltid kan appliceras på ett gränssnitt i ett sådant tidigt utvecklingsskede men en designer kan fortfarande få mycket användbara reslutat av att göra en analys..

Hur bestraffningstyp påverkar flow

Syftet med detta arbete är att undersöka hur olika implementeringar av Juuls uppdelning av bestraffningstyper kan påverka möjligheten för spelare att hamna i tillståndet som Csikszentmihalyi identifierade som flow. För att undersöka påverkan av olika bestraffningstyper på spelares upplevelse skapades tre olika versioner av ett plattformsspel med olika implementationer av bestraffningstyper baserade på Juuls uppdelning av bestraffningstyper. Ett antal respondenter fick spela alla tre versioner för att därefter, via semi-strukturerade intervjuer, försöka förmedla hur deras upplevelse varierade från en version till en annan. Undersökningsdeltagarna observerades under spelning för att försöka fånga spår av flow-tillståndet i deras kroppsspråk. Även deras prestation i varje spelsession lagrades för att möjliggöra en jämförelse av spelversionerna.

Autenticitet i ett öppna data-sammanhang : Utmaningar och möjligheter ur ett arkivvetenskapligt perspektiv

By tradition, archival sciences has emerged in a context with defined information processes, with explicit information producers and custodians to which consumers make requests for the information. In this process, the archival science has developed methods and strategies to preserve authentic and reliable records and by that providing trustworthy information. In an online society, people are using the internet to get information for different purposes. Even though there is no legal obligation to guarantee the authenticity, it is of societal importance that the end users get trustworthy information. In this online context, open data is a trend that is growing fast over the world and it is interesting because its conditions raises many questions regarding authenticity.Since open data is free to reuse, link and combine with other information, and it is preferably in primary format it raises questions about how to maintain the integrity and identity of the information, which is the constituents of authenticity as it is used in this work.

Från retailer till e-tailer: En studie av konsumentattityder

With the fast development of Internet and the e-commerce during the last decades, retailers are now introducing online stores. This has been adopted as a common strategy within the industry and the phenomenon seems likely to increase over time. Theory based on brand extension is used in this study to explain the effects on brand attitude and the link with willingness to pay when a traditional retailer introduces an online store. We execute an experimental study in order to investigate the effects where we use the offline- and online channel as well as two brands with different strengths as independent variables. Results show that brand attitude and its link to willingness to pay transfers to the online channel.

Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

Swedish Open: Konsekvenser av ett evenemang

Syftet med föreliggande studie är att få en ökad förståelse för vilken betydelse tennisturneringen Swedish Open har för Båstad genom att undersöka vilka effekter som evenemanget genererar utifrån en hållbarhetsaspekt.Studien utgår ifrån ett fenomenlogiskt och konstruktivistiskt synsätt. Vidare utgår den från en abduktiv forskningsansats med hjälp av en kvalitativ forskningsmetod. Denna kvalitativa metod görs med hjälp av egna primärkällor som består av tre djupintervjuer med nyckelpersoner som på olika sätt kommer i kontakt med Swedish Open. Ytterligar sex kortare intervjuer görs med lokalinvånare i olika åldrar..

En bra Chef går hem : - en undersökning av Landstinget i Värmlands chefsbrev

Internal communication is very important for the success of an organization. The county council Landstinget i Värmland is a large organization with many managers on different positions. Every one of these managers gets an email every week, with the message that a new manager letter, called Chef, is published on the intranet. With my paper I am examining what the managers think of this letter, how they use it and if managers on different positions differ from each other in opinions about and use of the letter. I want to find out if there is a need of Chef as a part of the internal communication of Landstinget i Värmland.To answer these questions, I have chosen a quantitative method in the form of a questionnaire which is send to all the receivers of the manager letter.

Ternära koder för variabelt felskydd

Ternary codes for unequal error protection is a part of a communication system where different parts of the information to be transmitted can receive different amount of error protection. There are a lot of applications where the channel conditions fluctuate so that reliable or acceptable communication can not be guaranteed. Regardless whether the fluctuations of the channel are intentional or not the idea is to let the coderate decrease so that the error correcting capability can increase for the part of the information to be more protected. By using the support, the nonzero positions of the ternary code, a new binary code can be extracted with properties different from the ternary code in the sense of cardinality and minimum Hamming distance. When the channel conditions are good the receiver decodes the message using ternary decisions and receives all information included in the codeword.

PRESTIGE, KARRIÄR OCH OPEN ACCESS Forskares syn på publicering i vetenskapliga tidskrifter

Dissatisfaction with the current market for scientific publishing, dominated by a few large publishers able to obtain high subscription fees, gave birth to the Open Access movement. One problem for the Open Access movement, which aims at making research results freely available, is that scientists are reluctant to publish in journals that are free on the Internet, so called Open Access journals. This master's thesis aims at showing how scientists reason about their own publishing in scientific journals. It is investigated which factors are important when scientist decide on which journals to send their articles. The aim is to increase the understanding of scientists' views on Open Access.Six interviews were conducted with scientists in Biomedicine at Lund University.

Isproblem i Barduelva

I Barduelva som ligger i norra Norge uppträder ett dämningsproblem från en isdamm, som tidvis orsakar översvämning och produktionbortfall för Statkraft. Isbildning i rinnande vatten domineras av att iskristaller bildas i under- kylt och omblandat vatten, kristallerna växer till sig och successivt utvecklas s.k. kravis. Då vattnet har en hög turbulens når inte kravisen till ytan, utan en del kommer att häfta på bottnen (ankaris), vilket kan vara början till en isdamm. Isdammar av detta slag tender att bildas då bottenlutningen ökar med ökande omblandning och värmeutbyte med atmosfären som följd.

Nitrogen flow in Scania : substance flow analysis on a regional level

In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.

"Man vet inte vad man inte vet". En studie av informationsflödet inom Gatukontoret i Borås Stad
