This thesis was carried out at Atlas Copco Tools and Assembly Systems. The purpose hasbeen to develop a design tool to be used for development of new electric motors for AtlasCopcos electric nutrunners. The focus of the thesis has been to increase productivity bydecreasing the power losses in an electric tool. The productivity is defined as themaximum number of tightenings a nutrunner can perform without becoming too hot.Before starting the development of this design tool an existing Matlab script, whichcalculates the losses in a slotless electric motor, has been studied and modified torepresent the real losses in a better way. The modification has been made by performingpractical studies of different losses and then adjusting existing parameters in the Matlabscript.Because design changes in one part of a mechatronic system can lead to a decrease inperformance of another part the choice of parameters that can be changed has been madeso that other parts of the system is affected as little as possible.A study of the existing tools efficiency during an entire tightening has been made toincrease the understanding of when and where the different losses appear and to comparethe modified Matlab script with the measured values.The design tool was formed so that it executes the Matlab script, that calculates thelosses, for a number of different design options and stores the alternative which producesthe least losses.

Balcony Art is an idea for a new kind of furniture group for those who have limited space on their balcony. This report will discuss conceptual and part of primary construction of the chair and table for use on balconies, how the products developed from an idea to primary, preliminary products.In the conceptual design part, the report will discuss how product requirements and specifications are developed and how these controls the design.In the primary construction, the report will discuss the products journey from sketch to functional CAD models and how the products of individual parts are designed and how the durability calculations affect the design..

The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.

The thesis was performed at the lighting company Zpecta AB. Zpecta needed to develop alternative attachment of their LED-luminaire Capella. Today Capella attaches in metal ceilings with four magnets. Zpecta got indications from their customers that there was a need for other attachments. The purpose is to determine the customer?s requirements and the interfaces that are considered for Capella.During the thesis, Capella was only on the market for testing and evaluation.The thesis was initiated to create a specification.

Hidden away in the pristine landscape on the northeast shore of the Dominican Republic, the remote village of Miches is on the verge of shifting its economic resource base from traditional fishing into what could become an international model for sustainable tourism. The aim of this thesis was to produce a vision of a waterfront park near the center of the village; demonstrating concept-based landscape design that reflects the goals of sustainable development originating from the local incentive structure. A composite landscape analysis and design concept both served to inform and guide the design work, which was executed through model building, hand drawings, and production of a visual presentation in the format of an architectural competition entry. The design concept, All invited, signifies the distinction between the development that is about to take place in Miches and the otherwise common all-inclusive resorts, where tourists are set apart from the local community and spend most of their time within the fenced-off premises of the hotel. All invited also captures the typical Dominican hospitality, and mirrors the aspirations of turning Miches into a safe and welcoming place for visitors. The result is a public park design that is equally inviting local residents as it is to tourists, and where the unique qualities of the site are emphasized without being exploited.

The goal of this thesis is to design an attachment between a duct and a pod. A pod is what could be compared to an outboard engine for larger vessels. The pod is placed on the outside of the ship?s hull and can rotate 360 ?. A duct is a large steel ring that can be placed around the propeller on the pod to increasethe propulsion force of the ship in lower velocities.

Immersion is a construct that measures how deeply engrossed a user is with any mediated situation. In the field of game design, immersion is a significant aspect of what makes a game enticing, and as such it is of pivotal importance to create and maintain it to keep the player's mind off the real world while inside the confines of a game framework. According to the GameFlow theory, it is one of seven key tenets of evaluating and implementing a successful game design. Yet, certain multiplayer online games are designed in a fashion that in some cases seem to break immersion, where the player is frequently put out of action, sometimes for minutes on end. In this study, using online questionnaires, we discover that players, despite claims otherwise, seem to be in several ways affected negatively by this breaking of immersion.

Gungstolen är en möbel med en säregen relation till sin brukare. Känsloladdad, lite opraktisk men omtyckt. Jag önskar att fler ska få uppleva glädjen och stoltheten i att bidra till skapandet av en möbel. En träram som fylls med personligheten av sin brukare. Kan detta också göra relationen till möbeln starkare?.

The purpose of this project was to design an adjustable gutter bracket for Lindab Profil AB. Lindab currently manufacture a gutter bracket that is adjustable in angle, however, this model has some drawbacks.  One of it´s shortcomings is that it is somewhat difficult for the customer to mount.  Another problem with Lindab?s current model is that the design makes manufacturing unnecessarily complex. The new gutter bracket, that we have constructed, does not have these problems. It is adjustable for different roof pitches.

This report describes procedures and preparations made for developing a mobile application.Using a questionnaire and usability tests, I have developed a design document for a parkingapplication for the iPhone 4. The purpose of the application is to help drivers find allowedparking spaces thus making roads safer for everyone while the driver avoids parking tickets..

By doing a study of Stapelbäddsparken from a gender perspective I have been investigating and analysing physical planning and landscape architectural design. My intention with this thesis is to reflect on what a gender perspective in physical planning means and what kind of consequences and effects it could have on physical planning and outdoor design. Gender is something that is created, moulded and transformed by social and cultural processes. And it also includes a dimension of power concerning the knowledge of the relationships between women and men where the standard in today?s society is still men?s interests. To implement gender in my analysis of the park I have been observing how the park is used and who is using it. I have also been investigating who?s needs and wishes that has been provided for in planning and design.

Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design of the fans for the quenching ovens, and the goal is that the new fans will bring cost savings for Scana-Booforge.The design development process started with mapping out the environment in which the fans operate, and with analysis of the existing fan structure and damages, in order to establish the cause of failure and of short durability. The performance of the fan were also established at this stage.

This paper accounts for the work with a website for a company whose real name will not be disclosed in the text of this paper. Instead, they have been assigned the fictitious name Larmbolaget, which can be translated as ?The Alarm Company?.During our work with Larmbolaget?s website, we consulted a selection of accessibility guidelines from the Web Content Accessibility Guidelines (WCAG) 2.0, developed by a working group within the World Wide Web Consortium, as well as a number of design principles and heuristics outlined in this paper. We also conducted several usability tests on users from our intended target group. All the measures taken were an effort to ensure that Larmbolaget?s website be as accessible and usable as possible.Our conclusion is that the resulting website does comply with the accessibility guidelines and design principles described in this paper, and thus we consider it to be accessible and usable to a wide range of users, including those with disabilities..

Ett community är en mötesplats på Internet där människor kan hålla kontakt, lära känna nya människor, diskutera osv. Det finns idag en mängd olika communities med många olika inriktningar. Communityn är idag mycket populära sidor på nätet och vissa har enormt mycket besökare och tjänar stora pengar. Det kan därför vara svårt att locka medlemmar om inte communityt innehåller nyheter som inte redan finns. Målet med det här arbetet har varit att skapa en tilltalande och användarvänlig design till ett community med ett sommar, fest och rese- tema.
