Erfarenhetsåterföring i praktiken : En studie vid Jernhusen AB
This examination has been made in cooperation with Jernhusen which is an estate company owned by the government, with estates along the railways in Sweden. This assignment is to help Jernhusens business area Projektfastigheter with their experience feedback, which is to-day almost absent. Business area Projektfastigheter has the task of supporting Jernhusens three other business areas with skills and resources for the estate projects that Jernhusen runs. Jernhusen must become stronger with the collecting of experiences and as a business because of the liberalization of the railways, which leads to a more competitive market. A tool for this is successful experience feedback.The concept of experience feedback is to gain experience across a variety of cases, where individuals and/or groups can chose situations with relevant similarities and differences with current case.
Nytt koncept för linspridning
Sammanfattning
Projektet, Nytt koncept för linspridning, vilket tillhandahölls av Abu Garcia,
bestod i att vidareutveckla multiplikatorrullen, Ambassadeur Classic 5000c.
Målet var att konstruera en multiplikatorrulle, med vilken fritt utkast
erhålls. På dagens multiplikatorrullar passerar linan genom linspridaren, detta
medför att linan följer linförarens rörelse under utkastet. Till följd av
linförarens rörelse genereras friktion, vilket i sin tur ger ett kortare kast.
För att öka kastlängden, skall linspridaren ej vara i kontakt med linan under
utkastet. Det är dock viktigt att linan sprids direkt på spolen vid påbörjad
invevning.
Simulering av bordläggningslucka
Kockums i Karlskrona har givit i uppdrag att ta fram lösningar till
öppningsmekanismen för större bordläggningsluckor på marina ytfartyg. De önskar
att luckans dimension ska vara max 10 * 3 m.
I uppgiften ingår att ta fram en lösning på öppningsmekanism, simulera öppning
och stängningsförloppet i Virtual Reality samt utvärdera konstruktionen enligt
givna lastfall. Acceleration är ett exempel på laster som luckan kan tänkas
utsättas för under öppet läge samt under öppning och stängning.
Första delen av rapporten innehåller principkonstruktionen, här har det tagits
fram ett antal lösningsförslag som visas med enkla skisser. Dessa utvärderas i
olika omgångar mot de krav och önskemål som tagits fram i samarbete med
Kockums.
Webbaserat resultat och uppföljningsprogram för idrottsförening
Students at the School of Engineering at Jönköping University have on behalf of the swimming organization ?Nässjö Sim och Livräddningssällskap? conducted research on how to monitor and evaluate swimmers and swimming groups in a simple and efficient manner with a focus on usability and user friendliness. Since no system existed that could meet these requirements, the client had a desire to tailor and develop such a system. The purpose of this work was to develop a system that would work as a tool to be used by coaches and swimmers alike and allow them to eventually follow the development of swimmers and swimming groups. The organization also wanted to have the ability to create tests and exams, both for land and water training, register these in the system and in a structured way know which swimmers took and passed these.For this thesis, the following questions functioned as a framework for progress.UsabilityHow to design a usable system and what is required?SystemWhat type of system is best suited to meet the client's requirements and preferences?Competition resultsHow can one retrieve all the competition results for swimmers of Nässjö SLS?DatabaseWhat type of database is best suited to easily share data with an external existing database?Usability has been the main focus throughout the project.
Studie av dagvattenkanalen utmed Sjöstadsparterren i Hammarby Sjöstad
In Europe, the central governments are the ones to coordinate the international standards and strategies regarding GPP; Green Public Procurement. However in Spain a GPP program was introduced late and only applied to the Central Government Institutions, (AGEA) (BOE nr. 027, 2008). These means that smaller administrations, such as, Autonomous Regions, Municipalities and Town Councils were not included in the program. The absence of a national program which excludes those governments made them introduce their own criteria for GPP, and the difference in criteria varies from one government to the other.
Optimering av reducerad bearbetning : högre skörd till lägre kostnad
Optimization of soil tillage and crop rotation is important in many aspects, but particularly in maximizing profit margins. Since the economic outcome is usually decisive, it can be interesting to study different combinations of soil tillage systems and crop rotations in order to identify the maximum economic outcome. How a crop functions in a particular tillage system determines whether it is profitable to grow that crop. Different tillage systems affect the soil and its processes in different ways. Reduced tillage often works best on weak-structured heavy clays and on silty clays.
Utveckling av säte till kulventil SKV
This report contains a degree project made by the mechanical engineering students Lennart Andersson and Daniel Jansson. The project has performed in assignment by SOMAS Valves AB in Säffle. SOMAS are leading in development on control and on/off valves. To maintain this position they always want to improve their products. One way in this development is valves that are more tightened.The purpose with our project was to investigate another seat design on a HiCo (High Cobalt Alloy) seat to a SKV 150 PN 25 valve and compare this to an original HiCo seat.By modifying the seat on a ball valve we want to achieve a valve that leaks lesser then a valve whit original seat.
Bedömning av området energi : En jämförelse mellan Miljöbyggnad, Svanen, FEBY12 och PHI
The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.
Automatiserad mätning av kvalité : Varför är inte all mätningautomatiserad?
AbstractThis bachelor?s thesis at the Department of Production Engineering at the Royal Institute of Technology in Stockholm deals with the subject of automated metrology. The degree of automation of tasks within production has been a growing trend but the measurement of quality has not followed the same trend. The main thesis follows:What incentives are there to automate the measurement of quality in production?What factors are crucial and why are not all metrology automated?The thesis comes along with a number of sub-queries and delimitations.The working method includes both theoretical and empirical studies.
Jämförelse av metoder för mätning av kroppssammansättning och energiomsättning
Syftet med detta examensarbete var att utvärdera tre olika metoder för mätningav energiomsättning hos människokroppen med förhoppningen att kunna komma fram till en enklare metod vilket kan underlätta främst för patienter men även för sjukvårdspersonalen. Utvärderingen grundas på mätningar av BMR.Det finns flera olika metoder att mäta energiomsättningen och jag har använt mig av indirekt kalorimetri (referensmetod), bioimpedansmätning (BIA) och Sensewear Armband. Den sistnämnda är en helt ny metod och det är denna metod som främst har utvärderas gentemot de andra. Mätningarna med alla tre metoderna utfördes vid samma tillfälle efter fasta för varje försöksperson (n=10)och patient (n=2). Armbandet bars i tre dygn, indirekt kalorimetri mättes under 30 min och BIA mättes vid ett tillfälle.
Kulturell påverkan på koncept
Dagens film och spelkoncept inom genrerna science fiction och fantasy börjar
likna varandra mer och mer och för oss känns inget längre annorlunda. Genom att
basera dem på historiska samhällen och kulturer hoppas vi på att bryta normen.
Vi hoppas att med detta som grund kunna skapa realistiska och trovärdiga
folkslag som skiljer sig från det som funnits tidigare. Detta examensarbete
handlar om konceptutveckling av en fiktiv värld och tre fiktiva folkslag.
Konceptet skall kunna appliceras på både film och spel men även litteratur
eller andra medietekniska områden.
Utvecklingen av mekatronikämnet på KTH : ? anställningsbarhet, forskning och innovation
This thesis examines history of the subject of mechatronics and innovation. The main reason tostudy mechatronics from a historical point of view is that it has never been done to a greater extent before. An overview is justified because various definitions have been used over the decades, but nowadays the subject has become more established. Focus in this thesis is mainly on development of the subject of mechatronics at Royal Institute of Technology in Stockholm. Innovation is the other aspect of this thesis.
PARAMETRISERAD DESIGN APPLICERAD PÅ EN MOTORSÅGSKEDJA
The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.
Fem-studie av rörelser i planet mellan bakaxelbrygga ADA1100 och centralväxelhuslock R780
This thesis has been performed at Scania CV AB Technical Centre in Södertälje and its aim hasbeen to study the causes and effects of deformations in the interface between the rear axlehousing ADA1100 and the central gear house R780 during operation. Design changes that wouldincrease the sealing capability of the studied interface are also suggested. Finite element (FE)and CAD software have been the primary tools in this study.Finite element (FE) simulations are used in the industry to predict and develop engineeringdesigns. The main motive for FE simulations has traditionally been to identify weak spots in thedesign, regarding high tensions and large deformations.The FE model is an aggregation of submodels and interface models that represents the rear axlehousing, suspension, central gear, central gear housing, wheels, bolts and weldings, and theirinteractions. The submodels have different material properties and they are connected withcontact interface models.Boundary conditions are defined on the bushings in front of the rear axle and on the air bellowsbehind the rear axle.
