Unified Flow Sensor
Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.
Studie av smörjsystem
Målet med detta arbete är att undersöka smörjsystemet på två utsatta leder på en Boomer E2C. Förfrågan om examensarbetet kommer från Atlas Copco Rock Drills AB i Örebro som också tillverkar maskinen.Atlas Copco Rock Drills AB har idag ett fettsmörjningssystem som upprätthåller funktionerna på lederna. Uppgiften är att sammanfatta och utvärdera dagens system samt att finna nya lösningsförslag som skulle kunna ersätta eller delvis ersätta systemet. Information har hämtats från dokumentation, ritningar och samtal med konstruktörer på företaget. Efter att alla förutsättningarna för lederna specificerats så har lösningsförslag sökts.
Jämförelsestudie avseende stomsystem : Ramverk eller fackverk/balk/pelar-system
Projektet omfattade en jämförelsestudie avseende stomsystem. Studien undersökte ramverk och fackverk/balk/pelar-system och genomfördes självständigt med stöttning av Ramböll AB´s kontor i Falun. Syftet var främst att undersöka vilka skillnader det finns mellan tvåledsramar och fackverk/balk/pelar-system för lätta hallbyggnader och försöka få klarhet i varför fackverk/balk/pelar-system är det dominerande systemet i Sverige eftersom övriga Europa har tagit en annan utveckling och domineras av tvåledsramar. Studien undersöker skillnaderna mellan systemen i en hallbyggnad med förutbestämda mått i stål.Inledningsvis gjordes en litteraturstudie för att få en bredare bakgrund av systemen och en bättre förståelse om förutsättningarna för varje system. Efter litteraturstudien kunde sedan ett typhus och beräkningsunderlag för jämförelsestudien tas fram.
Det tragiskas hemvist : En uppsats om relationen mellan plats och sanning i Heideggers tänkande
In the 1969 Le Thor seminar, Heidegger stated that his philosophical journey could be characterized by three different themes: meaning, truth, place. The first two of these have been the subject of countless studies and discussions, but the question of place is still relatively unexplored in Heidegger?s thought, despite the increased interest for this topic in his writings. Even though scholars like Jeff Malpas, Edward Casey, Stuart Elden and Miguel de Beistegui have written books and essays on the importance of the conception of place in Heidegger?s thinking, there are still many important aspects of this theme to be discussed, given the importance Heidegger himself ascribed to this topic.In this essay, I therefore wish to pose the question of how one can understand the relation between place and the role of tragedy in Heidegger?s conception of truth.
Bildanalys för navigering i autonoma sensor-platformar
Det bör vara möjligt att skapa verktyg för att beskriva scenarion och med hjälp
av tillgänglig
mjukvara för visualisering kunna spela upp både verkliga och simulerad bilddata.
Detta examensarbete beskriver hur några sådana verktyg tagits fram. Till
förfogande fanns en
stor mängd bilddata, insamlad på ett militärt övningsområde som dessutom finns
representerad
som en syntetisk omvärldsmodell. Insamlingen gjordes med en UAV (Unmanned
Aerial Vehicle)-
prototyp, som var utrustad med videokamera, IR-kamera och
tröghetsnavigeringssystem. För
att simulerad bilddata skulle få ett verklighetstroget intryck placerades
markfordon ut i den
syntetiska modellen på exakt samma position som under fältförsöken.
Markfordonens position
mättes in med DGPS och UAV:ns hastighet, position och rotation bestäms med GPS
och tröghetsnavigeringssystem.
Resultatet, i form av lagrad tröghetsnavigerings- och sensorstyrnings-data,
ges efter en Kalmanfiltrering och blir vanligtvis noggrannare än vad som
erhålls från de respektive
delsystemen.
Tyngdpunkten i arbetet låg i att ta fram Matlab-funktioner som plockar ut rätt
vy vid rätt
tidpunkt och åskådliggör detta på ett tydligt sätt, samt att placera ut
markfordonen enligt
de givna koordinaterna.
Utveckling och dimensionering av en lastupptagande provningsram
ÅF Test Center in Borlänge had a need to expand their capacity for compressive and tensile strength tests. They wanted to do this by using a hydraulic cylinder, which they already possessed, to apply the force with. This required a load receiving structure. The aim of this work was to design and dimensioning a test bench for a cylinder marked NIKE 300 tons. The work would result in a completed design proposal on a test bench which could manage to run the compressive and tensile strength tests of up to 3000 kN.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Whole fat versus low-fat dairy products for primary prevention of cardiovascular disease. A systematic review.Author: Josefine Lindqvist, Robin Järnmark, Mathilde OhlinSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2014-04-09BackgroundResearch indicates that dairy products seems to have a protective impact on the incidence of cardiovascular disease regardless fat content. Paradoxically the Nordic nutrition recommendations recommend an exchange of full fat dairy product to low-fat dairy products.ObjectiveThe aim of this review is to investigate whether the variation in fat content of dairy products have any bearing on the onset of cardiovascular disease. With regard to common risk markers for cardiovascular disease the outcome measures hypertension, hyperlipidemia and weight gain is examined.Search strategyThe searches were made in the databases Medline (23/1-14) and Scopus (6/2-14).Selection criteriaRestrictions: Human Studies, Adults, Randomized Controlled Trials, English.Data collection and analysisTwo RCTs were included. Validation of the separate studies was performed with SBU's review template for individual studies and GRADE was used for summarizing the evidence of outcome measuresMain resultsThe two included studies examined the outcome measures blood pressure, weight and blood lipids.
Konstruktion av patientsimulator för anestesimaskiner
A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.
Metodik för fastställande av bärförmåga på befintliga betongkonstruktioner
Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.
The Psychology Driving&Barriers to Skunk Work Project
The Psychology Driving and Barriers to Skunk Work Projects (referred to throughout this thesis as the paper) represents a study predominantly on Tetra Pak from a selective perspective, the innovators. Innovators both past&present whose initiatives contribute to the well being of Tetra Pak as well as one from Ericsson were consulted. As with individuals, organizations possess definable characters that are influenced by the various stages of their life cycle. Theories of corporate life cycle phases and organizational character analysis were therefore employed to identify and explain organizational barriers to skunk work leaders&managers. Predicated on the Organizational Character Index survey developed by William Bridges PhD (himself a recognized leader in the field of transition management) and administered to sixty-one managers within a Tetra Pak business unit established the benchmark.
PIEZOELEKTRISK TRYCKSENSOR : En undersökning om textil struktur och piezoelektricitet
Arbetet syftar till att skapa en prototyp av en textil trycksensor som kan känna av och skilja på olika typer av belastning. En lämplig metod för att på ett vetenskapligt sätt testa sagda prototyp har också utvecklats. Prototypen har tillverkats för hand på en datoriserad vävstol och de ingående materialen är piezoelektrisk poly(vinyldifluorid), PVDF, tvinnad tillsammans med ett konduktivt garn, Shieldex®, samt polyester. När PVDF-fiber utsätts för töjning genererar de en spänning, vars storlek står i relation till töjningen. Den vävda konstruktion som valdes till prototypen är en distansvara där väftinläggen lagts in i 7 olika lager för att skapa volym.
Hur kan personer med hja?rtsvikt testa va?rden i hemmet, fo?r en snabbare behandling och korrigering av medicinering?
- To be trapped in a roller-coaster That ?s how some of the patients are describing the situa- tion of living with heart failure. To be stuck in their home not knowing if they will have to seek care today and not knowing if they will have the energy to attend that birth- day party later this week.Each year 2-3% of the Swedish population are diagnosed with heart failure, which results in 30,000 new individu- als with the disorder. Cardiovascular disease is rapidly in- creasing in the world and before 2030, people with heart failure will increased by 100%. Our improved living condi- tions and better health have allowed us to grow older and made us more dependent on other types of care, care at home.Today the patients are only looking for changes in weight and if they have excessive water in their body.
Att konstruera en frack : En kvalitativ studie om studentfrackens upplevda gränser
This explorative study focuses on young, university attending males (22-27 years) and their understanding and pratice of the classic tail coat. It is based on five qvalitatively interpreted interwievs with a total of six participants, and through open questions regarding individuality and identicalness, limits and possibilities and inclusion and exclusion, a masculininty of a less contemporary hue takes shape. These conversations have revealed the tail coats potential of respresenting a male stereotype that can set a foundational and minimal standard for inclusion. Above this layer these males can then manifest and negotiate their masculine position in a homosocial hierarchy which decides the amount of passage, privilieges and confirmation of self- worth received for the wearer. These negotiation is performed by value bearing symbols (such as medallions, cordons and the like) allowed by the wearer and by the actions that systematically ensure that the lines of the tail coat are watched and unbroken.
Augmented Reality i mobiltelefonen : En kunskapssammanställning med trafikinriktning
This master thesis is about Augmented Reality (AR), a phenomenon that has existed since the mid-fifties but only recently has become available for the general public. This report is a knowledge compilation about AR, focusing on AR in cell phones and the use of the technology in traffic related situations.AR is usually described as adding a digital layer of information onto the real world. There are different technologies to make virtual images; in cell phones sensor-based and camera-based technologies are the most common ones.In this report, the market of AR applications for cell phones has been investigated. Three use cases have also been investigated in order to get more knowledge about the designers' thoughts and visions.In order to analyze the technology and the applications in a broader and more scientific perspective, two theories has been used: Situation Awareness (SA) and the Service Dominant Logic (SDL). These theories seem useful when reflecting on the Swedish road administrations vision, and to investigate what the applications and the AR technology can contribute to the traffic domain.The conclusions of this thesis are that:- AR can be applied on most of the human senses, but augmenting by visualization is most common.- The market for cell phone applications is growing rapidly: AR applications are relatively new but on the rise.
Dolda resurser : Att synliggöra icke materiella tillgångar
Background: Once upon a time the most important resources in an economy were tangible goods. Historically, Swedish company culture has been dominated by engineering and techni-cal innovation has been the focal point. Today, Intangible values drive product development and form a company?s differentiation. Intangibles have therefore become the most prominent resources in a company.
