Reglering av vridbord
This report describes a master thesis performed at Saab in Arboga. The main purpose was to build a controller for a system containing a turn table and an antenna beam. The idea is to use this system on a boat where it will be exposed to position disturbances due to waves. The desired behaviour is that antennas placed on the antenna beam should point towards the same target all the time. To solve this problem the system has been modeled and simulated in Matlab and Simulink.
Aktivt balanserad cykel
To conclude this year?s introductory course in Mechatronics the students, in groups of 6,constructed a prototype based on the technical requirements established by the course teachers.This year they consisted of the following: two wheels only, active balancing, remote controlledand able to stop when crossing a pre-determined marker on the ground. The project lasted for 7weeks and the result is a working prototype and this report.The report reviews the chosen solution, subsystems and the finished prototype as well assuggestions for improvements, discussion and analysis.The prototype constructed embodied most of the group?s earlier individual technical specialtiesand consists of the following: a flywheel for balancing, ultrasound for angle measurement, areflective photomicrosensor to detect the marker and Bluetooth for the hand control..
CTF ur ett ekonomiskt perspektiv : en analys för storskaliga växtodlingsföretag
Denna uppsats är skriven inom ämnet Företagsekonomi och omfattar 15 högskolepoäng på C-nivå på Institutionen för ekonomi vid Sveriges lantbruksuniversitet. Tanken bakom vår uppsats är att ge en bild av vad controlled traffic farming (hädanefter förkortat CTF) är, samt om odlingstekniken kan ge bättre lönsamhet i svenskt lantbruk. Förhoppningen är därmed att uppsatsen skall ge en grundförståelse inom ämnet.
CTF innebär att permanenta körspår anläggs och att all fälttrafik sker i dessa körspår. Följderna av detta blir således att åkermarken mellan körspåren övergår till att vara mer lucker, eftersom lantbruksmaskinernas markpackning koncentreras till körspåren. Markpackning är ett av de stora problemen i dagens jordbruk och målet med CTF är att öka lönsamheten genom högre fältavkastning till följd av bättre markförhållanden för grödan.
Studien utgörs av en jämförelse mellan konventionell plöjningsfri växtodling och odling med systemet CTF.
Det (o)möjliga föräldraskapet : Reproduktion och etablering av en god familjerelation
This theises focus on how a ideal parentship can be reproduced and established in an organization that is incorporated in the familycourt, provided by the social institution. The organization provides help for parents and children during and after a divorce or separation, the organization also provides help for families where violence has occured or in cases when parent and child doesn´t know one another. When a custodial dispute arise´s and one of the two is granted soul costody of the child, the guardian in most cases is the mother. Therefor this organization mostly handels fathers and their children. The study shows that gender, class and possesing of the right will are the three main aspects that have an effect on who ends up at the organization.
Temperaturstyrning av aluminiumextruderingsprocess
In this final thesis a rough description of aluminium extrusion is made, the importance of temperature of both the raw material and the extruded profile for a good profile quality. The difficulty in controlling these temperatures are discussed and attempts to increase the control are described. The attempts are basically made by controlling the furnace that is heating the raw material. This is done in a manner that the raw material reaches its final temperature shortly before it is extruded. An IR-camera at the press can be used for profile temperature measurements.
Analys av massapumps- och mixerarbete vid Metsä Board Sverige AB, Husums Fabriker : Energibesparingsåtgärder vid blekeri 4 & 5 med jämförelse mot ny utrustning
Husums plant has a selection of different pulp pumps at bleaching plant 4 and 5. The displacement- (HC-pump, Sund Defibrator PTD-60) and centrifugalpumps (MC-pump, MCA 42-200, MCP 30/20) are of interest in this report. The centrifugal pumps are controlled by throttle valves, which result in an energy loss. Chemical mixers are used to mix ClO2 into the pulp before proceeding into a holding tower where the bleaching process occurs.The energy demand of the different positions has been measured or calculated to be used in comparisons against new equipment. Quotations were requested and delivered from Valmet and Sulzer.
Detaljplanera Trygghet : En studie om hur trygghet kommer till uttryck i tre detaljplaner i Umeå
This essay aims to examine how safety is reflected in local plans. This was done by describing the physical environments, which are addressed in the local plans and its impact on safety. It has also been undertaken to see if certain physical environments with respect to safety have been addressed differently.The paper is made with the qualitative method Thematic analysis. The method is used to analyze the three local plans that have been available during the essay. The analysis was done with my created themes Traffic separation, Accessibility, High vision, Light and bright and Human presence.The results have shown that the local plans takes up physical environments that are good for safety.
Utformning av ett materialflödessystem anpassat för HSP-Gripens produktion
Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.
Verktyg för utveckling av terrängparker inom skidanläggningar. : Shaper
Today we can create digital 3D models which can be realised almost instantly through production methods such as 3D printing and computer controlled milling.What if this same technology could be applied to the development and construction of terrain parks?With snow as the material tools could be developed using similar principles to design and sculpt the surface, only on a larger scale.How would terrain park designers adapt their process to use this new technology? In this Industrial design thesis I explore how the ideas of the terrain park designer can be expressed through such a system with focus on the designers knowledge and skill without the need to learn complicated 3D programs.Sketch, create, ride. .

Kartläggning av tekniska och processrelaterade problem och dess utvecklingsmöjligheter vid biogasanläggningar
Biogasanläggningar, som behandlar fler än en typ av substrat, så kallade samrötningsanläggningar, är relativt unga anläggningar. De första byggdes under tidigt 90-tal och står idag för omkring 28% av Sveriges totala biogasproduktion. Felaktigt inkommande material och det matavfall som tas in som substrat ställer höga krav på anläggningarnas utrustning, med därtill kopplade problem. Syftet med detta examensarbete var att genom intervjuer genomföra en kartläggning av befintliga tekniska och processrelaterade problem för två biogasanläggningar med samrötning samt en förbehandlingsanläggning. För att undersöka alternativa tekniker och utrustningar till identifierade problem genomfördes litteraturstudier och kontakt togs med leverantörer av biogasutrustning.

Search terms that were used were: breakfast,breakfast quality, children, glycemic index, energy intake, obesity.Selection criteria: Randomized controlled trials and cohort trials, breakfast eatingindividuals, children and adolescents under 18 years old, reported glycemic index. Outcomemeasurements: Energy intake.Data collection and analysis: Six original articles met the inclusion criteria and werereviewed by the SBU audit template for randomized and controlled studies. There after onearticle was excluded because of very low quality of the study.
Framtagning av ICC-profil för VTAB Backa
The following degree project deals with the production of an ICC-profile, this in the form ofproducing ICC-profiles for VTAB Backa. The company previously had their own profile butthey weren?t satisfied, so earlier this year they started using the TU standard profile, but theyalso wanted a complement to this in form of a profile created for solely their printing press.The separation settings used when creating the new profiles were based on information fromTU and their profile. Two basic profiles were created and then edited to obtain a better result.The test printings made with the edited profiles showed that the less adjustments that are made,the better. It was also discovered that the TU standard profile eliminates the highlight toneswhiles the new profiles are somewhat darker.
