In this report a new gear concept is evaluated using the magnetic finite element method (FEM)software MagNet and Ansys as well as the mechanical FEM software Abaqus. The gear conceptis evaluated in terms of maximum torque capability, torsional stiffness, gear ratio and efficiency.ABB Corporate Research has proposed a new gear concept which should be less expensive thangearboxes used today. The new concept is called aMagnetic Harmonic Traction Drive and usesthe principles of a harmonic drive gear to achieve a high reduction ratio. The gear conceptreplaces the wave generator used in traditional harmonic drives with magnets and uses tractioninstead of gear teeth to transfer the torque. The main components in the gearbox are the magnets,the flexspline, the magnetic portion and the circular spline.

Staden Sulaymaniyah ligger i den kurdiska delen av Irak och har på senare år utvecklats då många valt att flytta från landsbygden till den centrala delen av staden. Nybyggandet sker under tidspress och långsiktigt hållbara lösningar prioriteras inte. Målet är att ta fram ett hus som är anpassat för majoriteten av befolkningen och samtidigt få ett bra och energieffektivt inomhusklimat. En faktainsamling genomfördes för att ge bakgrundsinformation till projektet. Vidare gjordes en planlösning till huset i AutoCAD vilken har använts som grund till utformningen av huset och smarta lösningar.

Since the demands from authorities regarding lower energy consumption havebecome increasingly strict, this puts new pressure on designers and builders, who notonly have to ensure an esthetically pleasing building, but also make sure it issufficiently efficient to pass under new laws and regulations.This thesis takes into consideration a wide range of various parameters and theireffect on a building?s energy consumption. For this evaluation a computer softwarecomparison between the two programs Autodesk Ecotect Analysis and AutodeskProject Vasari was performed.Autodesk Ecotect Analysis is better suited for studies made on individual factors whileAutodesk Project Vasari is better used in experiments regarding the geometricalshape of the stucture itself.The results from the two different software tools used, give us both differences andsimilarities. For instance, both software programs produced the same resultsregarding the importance of the windows of the buildings to ensure a highly energyefficient building, both when it comes to the windows size and their U-value..

This project has been about making a design suggestion for a boat accessory that adjuststhe distance between a sail-or motorboat and the dinghy, which is connected by a rope inthe stern. Today this is all done by hand and can lead to problems when it comes tostressful situations such as harbors and narrow passages.A company called Sailsafe came up with the idea and the construction, which they alsohave tested. I found them through an acquaintance at Dacat AB where I did an internshipin the fall of 2010.Using sketching as the primary tool I?ve worked in an almost-real design project with theaim to develop my skills and give the company a relevant design suggestion. Dacat thenhelped me with a 3d model in Alias, which was printed in 3d and painted in thepaintworkshop at school..

Den här uppsatsen handlar om rörelsen intelligent design, som tror att en intelligent skapare ligger bakom stegen i evolutionen. På så vis blir inte evolutionen en slumpmässig sak, utan en sedermera intelligent designad evolution. Den här intelligenta skaparen är med andra ord Gud. Uppsatsens ämnar  undersöka intelligent design och gymnasieskolan, närmare bestämt hur ID korrelerar med didaktik. Rent konkret är syftet med uppsatsen att se hur man i de centrala didaktiska frågeställningarna bemöter intelligent design i religionsläroböcker på gymnasial nivå.

The process of producing a video game is one that goes through a number of phasesduring the span of the entire production. One of these phases is the concept design phase,which is part of the pre-production. This phase is an important aspect of the productionas it is where all the different parts and ideas concerning the game are brought togetherto define what the game is going to be. Though a clearly important part of the videogame production surprisingly little research have been done on the subject of conceptdesign. This thesis presents what place concept design has in the overall game productionand how the design process is handled.

Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.

This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.

In this report you can get a complete instruction about how to build your own development system for the PIC-processor. This card will be used for laborations for the students at LITH-ITN. With this card you can send new assembler codes (new instructions) down to the microprocessor via the Serialport on your computer. Then the new instructions for the microprocessor will start to execute. We made a solder paste stencil at Campus Norrköping solder paste stencil laboratory.

The purpose with the report is to show that it is possible to design a class-D amplifier, using a programmable FPGA mounted on a developing card from Xess and a H-bridge. The FPGA was programmed in VHDL which is the language the software from Xilinx use to implement a logical function into the FPGA The logical function corresponds to a modeling of the music signal and the modeling can be described as a comparator which compare the music signal with a triangle wave and as a out signal produce a pulse width modulated (PWM) signal. The report is also a review and evaluating of two different modulating technologies, AD- modeling and BD-modeling. A detailed part about how the H-bridge was designed and how it works. The result of this project is a working audio amplifier to a significant lower price than the products in todays market..

This essays purpose is to accentuate the meaning of the knowledge of the design elements color, formand texture in the hair design education. Both the Bauhaus school and Pivot Point educationcampaign close knowledge in color, form and texture. In my study of the literature I compared theBauhaus school with Pivot Point International Inc, study material for hair design education. From thesimilarities in this material I develop a project in color, form and texture. This was a teaching test forstudents in the hair design education at the upper secondary.

The aim has been to investigate and describe how gender-neutral design, concerning typefaces and colours, can be created. Based on my results I?ve designed a cover for a recipe-book to make it appealing to both women and men. I have been doing my research based on questions such as; Does feminine and masculine design, concerning typefaces and colours exist? And if so what characterizes it? Does gender-neutral design, concerning typefaces and colours exist? And if so what characterizes it? Is it possible to design a cover for a recipe-book in a gender-neutral way, concerning typefaces and colours? The first part of my research consists of a literature study based on keywords such as gender, graphic design, gender theory, typeface, androgynous, visual communication, colour, shape, feminine, masculine, and book design.

The aim of this study was to design short interventions based on the literature study, which will change the pupils? posture on mathematics and connections between problem-solving in mathematics and everyday life. An experimental group of 17 pupils in fifth grade participated in the study and were educated in everyday mathematics 20 minutes a day during four weeks. The intervention was measured in a pre- and after questionnaire, in order to control the design and discover possible changes in the pupils? posture on mathematics and connections between problems and everyday life.

This study investigates if, and in that case, how design theory is applied in practice in the web development field. Prior research has focused on methods used in the web development field. We wanted to study the designers role in a web design process by comparing existing designer roles with design theory literature. We did qualitative interviews with two practitioners at two different communication agencies in northern Sweden. Based on our qualitative data and literature review we have concluded that a designer has to devote a lot of energy on requirements engineering in order to develop a clear understanding of the design situation..
