Möjligheter och hinder för att utöka omfattningen av RoHS-direktivet
The RoHS Directive was introduced in order to restrict hazardous substances in Electrical and Electronic Equipment, EEE. It currently restricts the use of six hazardous substances/compounds; cadmium, lead, mercury, hexavalent chromium, PBB, and PBDE. The RoHS Directive currently includes category 1-7 and 10 in the categories of EEE listed in Annex 1A to the WEEE-Directive (Waste of EEE). The aim with the report is to investigate and elucidate prospects and obstacles to increase the scope of RoHS. This report mainly considers the inclusion of product categories 8 (Medical Devices) and 9 (Monitoring and Control Instruments).
Automatisk lockmekanism : från idé till prototyp
Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.
Interactive Visualization of Statistical Data using Multidimensional Scaling Techniques
This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive Components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize.

En ekonomisk utvärdering av framtida biobränslebaserade processkoncept inom energisektorn
The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key Components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of Components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.
Standardisering av bakpanel.
HAFA Bathroom Group has given us the assignment to develop a standardized back panel for their bathroom cabinets. This cabinet is going to be applied to most of their current and future cabinet solutions. To this point, they have constructed unique suspensions-and back panels for most of their cabinet models. They have also been forced to pull wiring and assemble the cabinets differently because of factors like; position of the wall sockets, dimensions of the cabinets and their shapes.The company wants to distance themselves from their current solution, firstly because the cost of having manpower to design each individual suspension solution, secondly because they will save a lot of money when the manufacturing process requires a minimum of Components to be constructed. As a result of this, the company can use their resources better to develop future products.The main idea is that the consumer isn?t required to change the suspension or back panel when they decide to buy a new cabinet.

ABC och ekonomisystem : En studie av Volvo Construction Equipment Components AB
The accounting information system comprises budgeting, accounting, and costing. The accounting information system has, traditionally, constituted an integrated system where the different elements collaborate. If ABC is introduced this order is disturbed, since ABC is based on another logic which cannot easily be integrated with budget and accounting. ABC, therefore, is usually used parallely to the conventional costing method. There are, however, companies that have taken its ABC one step further by letting it replace the old costing model and integrate it with the accounting information system.
Liten förändring, stor skillnad : En kvalitativ studie om logotypers påverkan på den visuella identiteten
The purpose of this paper is to examine the role of logotypes within the visual identity and identify possible reasons that motivate companies to change their logo. This paper should also clarify how different parts of the visual identity affect each other and how they are interconnected. The thesis research question is formulated with the purpose in mind and has led to the following question: How can a logo change contribute to enhanced visual identity? Since we wanted to obtain a better understanding of the chosen research area with help of interviews have we chosen a qualitative method for this thesis. During the process we have let the empirical material control the chosen theories.
Effektiv materialförsörjning i en försörjningskedja hos ett MTO-företag: En fallstudie på ABB Components i Ludvika
Den växande konkurrensen mellan företag har medfört att dess försörjningskedjor blivit ett medel för att erhålla konkurrensfördelar. Genom ökat fokus på lägre kostnader, förkortad livscykel på företagens produkter samt en ökad efterfrågan har resulterat i att försörjningskedjan hos företag ökat i komplexitet. Denna ökande komplexitet har skapat ett behov av att identifiera problem i försörjningskedjan. Vidare har den ökande konkurrensen medfört att ett företags ledtid blivit en viktig parameter. Hos Make-to-Order (MTO, tillverka-mot-order)-företag kan en kort ledtid vara en avgörande faktor för att bli ordervinnare.
