Utvärdering av ett system för Rapid Control Prototyping inom området robotstyrning
In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption andresource utilization on the used hardware and on usability for of software.A new mechatronic laboratory is under development at ABB Corporate Research in Västerås. Itwill be used for both mechanical and motion control design using existing and new hardware.The control structure in a traditional robot system will be interfaced to a rapid prototypingsystem which should allow easy changes to algorithms at different levels in the system.The system designated for this project comes from National Instruments and constitutesLabVIEW Real-time and FPGA module as the software tools. The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.

Fett - rekommendationer, kostvanor och konsumtion mellan 1935 och 2009
This literature research is meant to answer the following questions:
? What was the Swedes consumption of fat from 1935 to 2009?
? How has the fat consumption corresponded to the current recommendations?
? What is LCHF and which are the main advantages and disadvantages?
Fat supplies us with energy, isolates and protect organs from bumps and punches. Fat is insoluble in water but soluble in organic solvents. The properties of a fat depend on its structure. The most common fat in human food is triacylglycerides.
Ett HMI-verktyg med god användbarhet
Den snabba generella eltekniska utvecklingen har även satt sina spår i pumpbranschen. Detta har lett till en mängd nya funktioner och med det ett nytt uppförande hos pumparna. Detta har lett till missförstånd mellan användare och pump. Användaren tror till exempel att pumpen är trasig då den egentligen är automatiskt stoppad, vilket får följden att pumpen skickas på service även då den inte är trasig.Syftet med examensarbetet är att utveckla ett HMI med hög användbarhet som ser till att användaren inte missförstår pumpens nya agerande.Genom fältstudier erhölls kunskap om användaren, arbetsmiljön, arbetssättet och utrustningen. Detta lade grunden till hela arbetet.

Alternativ för värme- och kylaförsörjning i planerade kontorsbyggnader på Arlanda
This thesis consider alternatives for heating and cooling planned office buildings at Arlanda airport. The thesis is divided into three parts where the third part is a shorter synthesis of the two first. In the first part the energy demands of the buildings are modelled in a computer program. Two different building models are created, one more conventional and one with good energy properties. The results shows that with proper construction and ventilation systems etc.
It takes two to tango - En studie om relationers påverkan på samarbetet mellan leverantörer och detaljister inom sporthandelsbranschen
The trends in trade have been changing in the last few years. To offer a good product with agood price is not enough today, it?s also required that businesses create a good relationshipwith their customers and then do their best in maintaining it. It is now even more brandscompeting in the market, which indicates how a good relationship between the parties can bean important competitive advantage and also a significant variable.The goal and purpose of the study is to investigate and analyze the factors that influence thatthe supplier, in the sporting goods industry, is seen as a good supplier on the basis of theretailer's point of view. Then we want, from different sized companies, analyze and study howthey work with the key properties in creating a good customer relationship and hencecustomer satisfaction.
Grafisk utvecklingsplattform för signalbehandling - Design och implementation
We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.
Flerskiktat papper : en sammanställning av historia, teknik och forskningsresultat
Until the beginning of the 1900:th century the paper making process was handicraft. The paper machines that have been developed since then are as impressing in size as fascinating when it comes to the technique. The process has always been improved to give a better paper for lower costs, with as short manufacture time as possible. Stratified forming has been a reality since 1830. From the beginning it was applied to board and paperboard.

The theoretical yield value was estimated with a computer programme.
Instrument för bedömning av arbetsförmåga : En systematisk litteraturstudie
Att vara aktiv och klara av att utföra sitt arbete har en central betydelse för en individs hälsa och välbefinnande. Begreppet arbetsförmåga är ett komplext begrepp som beskrivs som flerdimensionellt. Vid bedömning av arbetsförmåga är det viktigt att bedömaren använder sig av tillförlitliga metoder som syftar till att hjälpa individen med sin fortsatta rehabilitering. Syftet med studien är att kartlägga olika bedömningsinstrument som mäter arbetsförmåga i olika avseenden. Bland annat vilket syfte instrumentet har, vilken datainsamlingsmetod instrumentet använder samt vilka psykometriska egenskaper som har prövats för instrumentet.
Microsoft Visual Studio och osCommerce - en jämförelse mellan två verktyg
This report represents a comparison between two different tools used to create an online store that was developed by two students at the Technical University in Jönköping. The web shop will be of great benefit to both customers and administrator in a food firm known as Mattias' Livs. The company wanted an online store that facilitates the sale section and gives a full control of their stocks. The aim of this thesis is to create an online store that offers customers the ability to shop online and help the staff to operate the company in a simpler and more efficient way, which reduces the need for human resources and thus leads to less costs for the company. The aim also includes a comparison between the two different tools used to create the online store.
Från förberedelse till upplevelse : Hur användarupplevelsen i e-handel kan efterlikna upplevelsen från en fysisk butik med fokus på single brandföretag
SyfteSyftet med denna studie har varit att undersöka vilka delar av upplevelsen som konsumenten får i en fysisk single brandbutik som bör efterliknas och lyftas in i samma företags digitala butik. Det har även varit att se hur väl företag förmedlar sina kärnvärden till sina konsumenter i den fysiska butiken. Slutligen har det undersökts vad som är viktigt när det kommer till egenskaper, funktioner och upplevelsen generellt för konsumenter när de handlar online.ProblemformuleringVad som gör denna studie speciellt intressant är att de single brandföretag jag har undersökt bedriver egen fysisk samt digital butik där de säljer sina produkter, men de har även återförsäljare som säljer samma produkter och blir på så sätt deras konkurrenter. Eftersom dessa single brandföretag har ett varumärke och kärnvärden som de måste leva upp till kan de inte sänka priserna på sina produkter på samma sätt som deras återförsäljare kan. Skulle då lösningen kunna vara att försöka lyfta in upplevelsen konsumenterna får i den fysiska butiken in i den digitala butiken för att förmedla en bra varumärkesupplevelse?SlutsatsDenna studie grundade sig på en modell som beskriver hur en bra användarupplevelse kan skapas.
Offentlig upphandling av ekologiskt producerade livsmedel : Ludvika kommuns, Borlänge kommuns respektive Smedjebacken kommuns erfarenheter av gruppcertifiering enligt KRAV
The Swedish public procurement correspond to approximately 400 milliard Swedish crowns every year which corresponds to about a fourth of the Swedish Gross National Product. Setting proper demands in the procurement is a useful tool to drive the development towards more environmentally adapted products and provisions. The Act on Public Procurement (Lagen om offentlig upphandling, 1992:1528) gives the municipalities opportunities to consider environmental properties during the procurement. This combined literature and empirical study investigates the experiences made by the three municipalities Ludvika, Borlänge and Smedjebacken during the process of certifying their school kitchens as organic in cooperation with KRAV. The main conclusion is that without compassion and curiosity for developing a green public procurement changes can be hard to implement.
New Generation Surface treatment for tools : A preliminary study
The surface finishing technique called black oxidation is currently being used on thetool holders made of low alloyed tool steel produced by Sandvik Coromant. Blackoxidation isn?t considered a sufficient technique because it doesn?t make the toolholders look like the quality products that they actually are. The reasoning behind thisis that the tool holders can show signs of corrosion after prolonged storing times orin countries with high humidity and temperature. The corrosion doesn?t decrease thetool holders performance, but the customers might believe otherwise.
