Utveckling och konstruktion av växellåda för elektroniskt styrda ställdon

The task of constructing a transmission has been provided to us by Digital Engineering, which is a company located in Hovmantorp. After meeting with Digital Engineering we started immediately with the brainstorming to find different ideas with pen and paper. After having presented a number of concepts for the company, we had finally chosen a winner. For the gearbox to be able to work in a good way the tension must never exceed the strain limit of the material. A Prototype of the gearbox was produced by TKB Modell.

Följ upp målarbetet hellre än målen

Background: The Swedish population is aging [1] and malnutrition is a common problem among elderly people [2]. A method called food registration is used to monitor the patients? nutritional intake, with the purpose of reducing the risk of patients deteriorating in nutritional status during hospitalisation. However, the current method is not satisfactory and many food registration lists are incomplete. [3-6] Thus, patients do not receive a qualitative nutritional care since the assessment of the patients? nutritional status is based on incomplete documentation.Purpose: The purpose of this master thesis is to increase the quality in the nutrition monitoring process in the geriatric units B72 and B74 at Karolinska University Hospital in Huddinge, Sweden.

Dämpning av ljud i Shift-by-Wire växelväljare : Noise damping in a Shift-by-Wire gear shifter

Constantly growing demands from the costumers in the Automotive industry forces the subcontractors to seek alternative ways to compete. One parameter of quality is the components tolerance against NVH(Noise, Vibraion & Harshness) aspects. Kongsbergs Automotive has developed a new gear shifter platform (Shift-by-Wire) that is sold to Alfa Romeo and used in of their car models. However, the company is not pleased with the components sound quality, therefore the main purpose of this thesis is to develope a number of concepts that is supposed to enhance these NVH-aspects.To get an understanding of the problem an analysis of the causes of the emitted sound has been done parallell to a product decomposition, function decomposition and a Ishikawa-diagram. Together with these methods has a litterature study been performed to get familiar with the physics of an impact and especially the emittment of noise.

Tillgängliga utställningstexter: En studie om att anpassa lättläst till en bred målgrupp

The purpose of this thesis has been to increase the availability the exhibition text at Eskilstuna Art Museum to make it easier for the target group to read and understand them. To get answers to my questions, I have studied relevant theories and methods, including textual analysis of the current exhibition texts. In my work, I have used the principles of the concept ?easy to read? but also considered the problems with this tool when I made my Prototype. After my studies, I noted that both the content and design needed to be changed to fulfill better legibility, readability and reading value..

Car Lock Improved by Configurable Key

When a car owner want to lock or unlock his or her car today, it?s preferable done by using aremote control. The system is really comfortable when the car owner is using the remote.A problem arises if a thief gets the remote.The thief doesn?t have to know where the car is parked, an approximate estimation where thecar is parked is enough.For instance, it?s enough to know which car park the car is parked in. If the thief knows that,he/she can repeatedly activate the remote control while looking for a car indicating with lightsand sounds.Because of the fact that a car usually indicates that it has been unlocked by making a shortsound indication, there will be no problem finding the car.The purpose with this project is to make a Prototype which makes it harder for a thief to findthe car.

Effektivt nyttjande av högeffektslysdioder i mobil belysning

The purpose of this master thesis has been to find different solutions to the design of a headlamp with a cluster of three or possibly four high power LEDs (Light Emitting Diodes). During the work, two different problems have been considered; how to design a lens in order to shape the light beam in a desirable way, and how to design a cooling system which will lower the temperature of the LEDs as efficiently as possible, still taking into account the geometry set by the optical solution as well as other given geometries. The results presented in this thesis are partly the outcome of a literature study, but derive mainly from a number of tests and measurements made on two test rigs and one concept Prototype..

This is a dissertation for a Bachelor Degree Project at the University of Skövde. The project is carried out in cooperation with the company Kinnarps AB.The objective of this project was to develop a new chair for café and lunch rooms, which should satisfy the markets expectations and demands and match Kinnarps AB?s assortment today. The project has contained everything from identification of user and customer needs and requirements to evaluation and building of a Prototype.The result is a chair with a frame of tubular steel and there is nothing like it in Kinnarps AB?s assortment today.

Förrotation till omrörare

The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

Optimering av distorsionseffekt med hjälp av Fourieranalys

In music performers and music-making are oftenused different distortion effects to give the desiredcharacter on the individual sound sources andinstruments. These have different names (fuzz,distortion, overdrive) depending on the character. Tocarry out this work, an extensive literature study ofthe circuit diagrams of a large number of the classicdistortion circuits implemented. In this work, adistortion effect of the character fuzz was createdfrom several other existing effects. MeasurementsFFT, frequency response have been conducted tovalidate the desired results along the given problem.The finished effect was named Instant Carlos and aPrototype was manufactured.

Loggning av användares interaktioner : utvärdering av användbarhet

The disconnect between assumptions regarding computer users interactions made by software engineers and the actual interactions do, for various reasons, not always match. Gathering actual usage data from user interfaces can enable software designers to make better educated decisions. By buildning a Prototype for collecting such data from a diagnosis tool for the automotive industry this project has shown not only how to benefit from the data but also how to perform the work. The data is 1 600 sessions consisting of 26 000 individual events. From this it has shown that available tools can assist in rudimentary questions regarding usage.
