Framtagning av demonstratorer

På Alfred Nobelmuseet i Karlskoga finns en avdelning som kallas Fiffiga huset. Där finns många experiment som besökare kan prova på, samt montrar som visar hur olika tekniska och maskinella apparater fungerar. Till utställningen och öppnandet sommaren 2009 ville de ha två nya demonstratorer. I rapporten kallas dem för reaktionstidsväggen och baklängesprataren. Reaktionstidsväggen skulle mäta besökarens reaktionstid genom att tryckknappar, med inbyggda dioder som slumpvis tänds, trycks ned i rätt ordning.

Parametriserad 3D-modell av cyklon : Parametrisering av en 3D-modell av ett cyklonfilter i SolidWorks för snabb framtagning av nya konstruktioner till Outotec Skellefteå

This bachelor thesis project has been executed at Outotec Sweden AB in Skellefteå. Outotecs main business focus is selling mineral and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement Device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

Reglering av matarsystem vid höghastighetskapning

Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like Device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.

Under hökens alla vingar : Fördelning och sortering vid upptagningshemmet i Sandsbro mellan åren 1933-1935

Under the hawks wingsDistribution and sorting at the upptagningshem in Sandsbro between the years 1933-1935This paper aims to study a so called ?upptagningshem? in Sandsbro, Sweden during theperiod 1933 to 1935. All the children during those three years were enrolled in theupptagningshem is included in the study, a total of 101 children. The main sources studied areprimary sources obtained from the county archive in Kronoberg which is shown in aquantitative method with the thesis that the upptagningshem works according to YeheskelHasenfelds ?people-processing technologies?, which acts as a sorting Device which meanscategorizing and classifying activities where different kinds of people are sorted and based onthe results taken care of, by appropriate other organization that can provide the rightresources.

Use me and play me : Grafiskt gränssnitt med Mp3-spelare för insulindoserare

Abstract: Typ-1 diabetes eller så kallad insulinberoende diabetes, drabbar vissa barn och tonåringar. De tvingas leva hela sina liv med att injicera insulin i sin kropp, eftersom deras egen kropp har slutat tillverka insulin på egen hand. Insulinpennan är typ-1 diabetikers medicinska redskap som de måste ha tillhands vid varje måltid.Syftet med denna studie är att utveckla och ta fram ett exempel på hur ett grafiskt gränssnitt med Mp3-spelare bör se ut i en insulindoserare som riktar sig till tonåringar. För att utreda hur gränssnitt ska utformas har kvalitativa intervjufrågor ställts till produktutvecklare, diabetessjuksköterskor och tonåringar. Vidare har också analyser gjorts på befintliga insulinpennor och Mp3-spelare.Resultatet av studien är en prototyp av en insulindoserare som simuleras i Shockwave.

Forensisk hårddiskkloning och undersökning av hårddiskskrivskydd

Detta examensarbete reder ut arbetsprinciperna för olika typer av hårddiskskrivskydd; hårdvaruskrivskydd, mjukvaruskrivskydd, hybridskrivskydd och bygelskrivskydd. Slutsatsen av utredningen är att endast hårdvaruskrivskydd Detta examensarbete reder ut arbetsprinciperna för olika typer av hårddiskskrivskydd; hårdvaruskrivskydd, mjukvaruskrivskydd, hybridskrivskydd och bygelskrivskydd. Slutsatsen av utredningen är att endast hårdvaruskrivskydd bedöms ha tillräckligt pålitliga skyddsprinciper, vilket motiveras av dess oberoende från både hårdvara och operativsystem. Vidare undersöks hårdvaruskrivskyddet Image MASSter(TM) Drive Lock från Intelligent Computer Solutions (ICS). Några egentliga slutsatser gick inte dra av kretskonstruktionen, bortsett från att den är uppbyggd kring en FPGA (Xilinx Spartan-II, XC2S15) med tillhörande PROM (XC17S15APC).

Visuellt typinstrument : en metrologisk studie

Visual Type Instrument - VTI, is a tool containing a typeface and a set of geometric calculations that generates numerical data in spreadsheets. The data is determined from the typefaces visual dimensions and is used to calculate leading, type size, margins and format. The aim is to offer, for all of those working with typography and design, a practical way to manage text, image and format in relationship to visual size. Instead of using point measurements, VTI uses a new Device called Edo. An Edo is the same as one twelfth of a millimetre.

Fem hjul och en propeller - En explorativ studie av alternativ till skrivbordsmetaforen

I dagens samhälle ökar datoranvändandet stadigt och datorerna blir snabbare och snabbare. Trots detta står utvecklingen på ett område i det närmaste still, gränssnitten till våra operativsystemet. Den stora majoriteten av dagens gränssnitt bygger på samma principer som när de introducerades för över 20 år sedan, dessa principer kallas för WIMP vilket står för window, icon, menu och pointing Device. Då operativsystemet kan sägas vara basen för allt arbete med en dator och till väldigt stor del styr effektiviteten i användningen, kan man undra varför inte mer har hänt på detta område. Syftet med vår undersökning är att visa på att det dels finns tydliga användbarhetsproblem med dagens dominerande gränssnitt, samt att det finns flera alternativ som erbjuder annorlunda lösningar.

Utvecklingen av samverkansregler mellan hälso- och sjukvården och näringslivet : Samverkan och krishantering i fält av legitimitet

Collaboration is a form of organization on the rise in Sweden. For health care, it is ofinterest to collaborate with industry to ensure that needs for specialist education andtraining are met and that products developed meet the relevant requirements.Conversely, industry actors have an interest to have a close collaboration with healthcare in order to gain insight into customer needs, provide information about theirproducts and to test products in development.The starting point of this study is an agreement and regulatory framework for formsof collaboration between public health care in Sweden in general and thepharmaceutical industry, the medical Device industry and the laboratory technologyindustry. The research questions concerns how this agreement has evolved and theprocess surrounding its emergence may contribute to knowledge about collaborationas a form of organization and the relationship to concepts such as legitimacy,corruption and institutional theory.By tracking the emergence of the current regulatory framework genealogicalthroughout history, the study uncovers how the agreements have played a role in andcontributed to the legitimization and institutionalization of collaboration practices andhow crises have changed the shape of the practices. A theoretical treatment ofrelevant concepts such as legitimacy, institutionalization of practices, corruption andstigmatization of organizations form the basis for an interpretation and analysis of theprocess.The conclusions of the examination of the historical process that led to the currentagreements contribute to empirical knowledge of how crises and stigma affect thelegitimacy of collaboration practices and how the repair of legitimacy can be donesuccessfully after a crisis. The treatment of the empirical material is also a historicalsource for the development of ethics agreements between public health care andpharmaceutical industry and the medical industry in Sweden..

Omkonstruktion av treaxlig plockrobot och dess plockverktyg

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built Device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

"The spirit of ayahuasca" : de kognitiva grunderna i erfarenheten av substansen ayahuasca: en fältstudie genomförd i Pisac, Peru

This essay aims at understanding the experience of the use of ayahuasca, and similarities and differences between interview protocols and socio-cultural identities. The work is based on field studies conducted in the Peruvian Andes, in the village of Pisac September to November 2009. What has emerged is that the experience does not seem to be dependent on cultural manifestations as much as it is dependent on general human cognition. Theories have been applied on an empirical phenomenological descriptive study. Various brain activities, along with mental mechanisms contribute to a deeper understanding of the findings in the descriptive analysis.It seems that the cultural differences, which I have classed as typological in the phenomenological study, mostly are expressions of meaning for the informants.

Att öppna texten för det främmande : en studie av litteraturens gränser och möjligheter vid gestaltningen av det främmande och annorlunda, den andre och av lidande.

The aim of this study is to examine ways of writing experiences of the strange and different, experiences of the other in his or her otherness and experiences of suffering. The study focuses possibilities and limits for the writing of these experiences and aims at finding a tangible way of writing literature. Part of the aim of this study is to elaborate a proposal for a way of writing experiences of the strange and different, experiences of the other in his or her otherness and experiences of suffering.    The material for the study consists of three different approaches to literature, in which theories on literature or analyses of literary works are presented. This material is initially analysed in separate analyses in which conceptions, strategies and methods for writing experiences of the strange and different, the other and suffering are identified. Secondly, the material is analysed in a comparative analysis, aimed at finding similarities and differences between the approaches but above all to let the approaches supplement and challenge each other.
