När kan Flow upplevas på arbetsplatsen?
Syftet med denna studie har varit att undersöka relevansen i tre olika teorier som förklarar hur Flow kan upplevas på en arbetsplats. Teorierna är skapade efter forskning från Csikzentmihaly, Hofstede samt Maslow. Undersökningen har skett på två olika arbetsplatser inom två olika yrkesgrenar för att finna om eventuella skillnader mellan dessa två arbetskontext kan påverka upplevelsen av Flow. Det ena företaget kategoriseras som en affärsmiljö och det andra företaget rubriceras som en kontorsmiljö. Tre hypoteser skapades som var för sig testade de tre teoriernas effekt på Flow.
Lärande och flow : Den optimala lärandeupplevelsen
Detta arbete har utförts för att undersöka frågeställningen ?Hur bör ett dataspels tutorial designas för att spelaren ska lära sig samtidigt som den främjar uppkomsten av flow??. För att besvara detta har teorier inom pedagogik, lärande av spel, användbarhet och flow samt mer generella teorier kring spel studerats för att skapa en teoribildning inom området. För att testa detta har ett spel med två olika tutorials skapats. Detta spel har sedan använts för att, med hjälp av två testgrupper, samla data om hur spelare lär sig samt deras flowupplevelse.
Kartläggning och visualisering av riggkonstruktionsprocessen : Fallstudie från Scania
Mapping a process enables a greater understanding of the work, and is standard to evaluate and improve a process. This thesis is conducted at Test Bed Mechanical Design at Scania in Södertälje. Test Bed Construction is a complex process, characterized by a large amount of creative work, technical challenges and coordination between different people and different organizational functions.The aim of the thesis was to identify the Test Bed Construction Process and to develop a visual model of the workflow that also served as support for the engineers in their daily work. During the mapping process, comparisons were made with previous research in lean product development to identify process improvement.A literature review on process mapping and process visualisation resulted in a method for process mapping. The study showed that research on process visualisation is neither structured nor well defined.
Flow i multiplayerspel
Detta arbete syftar till att undersöka hur Csikszentmihalyis teorier kring optimala upplevelser, eller flow-upplevelser, kan appliceras på praktisk speldesign. I arbetet kombineras Csikszentmihalyis definition av begreppet flow med Jenova Chens riktlinjer för flow-uppmuntrande design i singleplayerspel för att ge underlag för framtagandet av ett brädspel i vilket applicerbarheten hos deras teorier och riktlinjer på multiplayerspel undersökts. För att teorierna och riktlinjerna effektivt skulle kunna undersökas utvecklades det tre olika versioner av brädspelet som alla innehåller olika element som, enligt Csikszentmihaly och Chen, bör alstra flow. Ett flertal spelgrupper fick spela dessa tre versioner och via enkätundersökningar och intervjuer förmedla hur de upplevde de olika versionerna, både som individuella produkter och i jämförelse med varandra. De data som erhålldes från dessa undersökningar indikerade på att nivån av kontroll spelaren har över sin spelsituation spelar en väldigt avgörande roll i hur han eller hon upplever spelaktiviteten i sin helhet..
Karaktärisering av hårdmetallpulvrets råvaror och dess påverkan på pulvrets flödesegenskaper
This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.
Design av Riskdatabas : En studie för effektivare hantering av risker
Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.

Informationsflöden inom mobila-stationära organisationer
A good flow of information in organizations is one of the key aspects of how we define a well-functioning organization. The information flow could be internal as well as external between actors within as well as outside of the organization. In a logistics organization this flow of information is equally important as in any other kind of organization. In this paper we have explored information flows in logistics organizations by applying, boundary spanning and the mobile-stationary divide perspective. In boundary spanning the main goal is to erase or relocate some of the boundaries within an organization, in our case to make the flow of information internally as well as externally better.

Krafter på rörsystem vid transient flöde : En jämförelse mellan RELAP5 och Fluent
At Forsmarks Kraftgrupp AB (FKA) forces on pipe systems due to transient flow are frequently calculated as a step to verify their structural integrity. In nuclear industries these forces are often calculated with a one dimensional thermal-hydraulic analysis-code called RELAP5. When calculations regarding more complex geometries are needed, the three dimensional code Fluent is often used. This code is highly time consuming and requires large computational power.This projects aim is to compare calculations of pressure, flow and forces carried out by RELAP5 and Fluent for an arbitrary pipe section during transient flow conditions. This has been accomplished by constructing a simple geometry for which a transient flow is simulated in both programs.
Fältmätning och utmattningsanalys av hjullastarskopa
I denna rapport predikteras livslängden, med avseende på utmattning, för en hjullastarskopa. Två av de mest kritiska svetsarna utvärderas enligt IIW:s (International Institute of Welding) rekommendationer genom nominella spänningsmetoden, hot spot-metoden och effective notch-metoden. Beräkningarna utförs med hjälp av finita elementmetoden. Genom att utföra töjningsmätningar på hjullastarskopan i drift erhålls spänningsdiagram. Dessa uppmätta spänningsdiagram analyseras med rain-flow count-metoden.
VÄRDEFLÖDESANALYS AV PW1000G 30k TEC
The thesis work has been carried out at Volvo Aero Corporation (VAC) in Trollhättan. VAC has entered a partnership as developing and producing partner with engine manufacturer Pratt & Whitney and is currently at the starting phase of producing the turbine rear frame (TEC) to the engine PW1000.The purpose of this study was to create a report on process level that describes the conditions and the potential with PW1000 TEC to reach the product cost calculation taking into account lead times and describe alternative method solutions.The report describes a comparison between the present flow (2012), a flow based on product cost calculation (2016) and a potential flow (2016). The work has mainly been based on acquiring the knowledge and information available to inspect the present flow; this has been done by workshop observations, meetings and gathering of the information that is available on the work site for the PW1000 TEC.The information obtained has been merged into an Excel document, called Roadmap. It serves as a roadmap with current situation as the start and the potential flow for 2016 as the goal. With the roadmap as a tool, assumptions have been taken considering the flow and how it will change, where processes have been eliminated, reduced or marked as a problem..

Twittrande bibliotekarier: informationshantering 2.0?
The present study is embedded in the research field of Personal Information Management (PIM) and its goal is to contribute to this research area by showing information management aspects in untraditional contexts, as in the social networking site Twitter. The aim and purpose of this two year's master thesis was to investigate the beha-viour of librarians within the context of Twitter. The objectives of this thesis focus on the query of the informa-tion management aspect of Twitter, and on the investigation into whether Twitter offers the possibility to reach a state of flow while using it, as well as inquiring into the relationship between Mihaly Csikszentmihalyis flow theory and PIM. The theoretical framework of this thesis is centred upon the flow theory and the conditions that are necessary to reach a state of flow. To fulfill the purpose of this thesis a directed content analysis is applied as an investigative method, where its in-depth research aspects will be applied upon the empirical material, which contains 429 tweets.
Flow i undervisningen - en studie om lärares uppfattning om begreppet flow
Det här arbetet handlar om flow och hur begreppet samverkar med olika aktiviteter i våra liv. Bakgrunden till flow förklaras inledningsvis i kapitlet om teoretisk bakgrund och sätts senare i relation till inre förändring, socialt samspel, fysisk aktivitet, kommunikation, samt pedagogik. Syftet med arbetet är att ge svar på hur flow kan användas i undervisning. Som metod för datainsamling har jag gjort en gruppintervju med fyra lärare aktiva vid Musikhögskolan i Malmö. Gruppintervjun fungerade som ett vardagligt samtal mellan fyra personer och resultatkapitlet är sammanställt i sex rubriker: Introduktion; Personernas uppfattning om flow; Vägar till flow och hinder på vägen; Gruppflow; Flow, kvalitet och kommunikation; samt flow och undervisning.
