Undersökning av optimeringsalternativ för elektrostatlackering
This report describes a thesis done at the Jönköping University of Technology. The aim of this thesis was to create conditions to optimize an existing automatic electrostatic coating system by changing the technology for dispensing lacquer. To select the technology, a study of different dispensing techniques carried out which concluded that the piezoelectric membrane and electrostatic atomization are the most interesting techniques.In order to perform tests with dispensing techniques a demonstrator has been optimized. The controller and PC software of the demonstrator has been programmed to be able to send out PWM signals that control the dispensers. An adapter card was designed to control the piezoelectric membrane and a steering link to the electrostatic atomization has been developed for PWM signals up to 500V.The work has laid ground for a demonstrator where further testing of the dispensing technologies can be performed..
Förstärkning av bro 17-803-1 : En jämförelse av förstärkningsmetoder
AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.

BIM Building Information Model : Hinder & Drivkraft
The construction industry is a costly business such in respect of capital for most construction defects which then require rework, tear down and rebuild again. This study is meaningful awareness of tools that can reduce this best through communication and information sharing between the parties. The construction industry is known as temporary projects organizations, where the construction project consists of several actors who have to communicate and share information between them to avoid mistakes later in the build time. These actors are bounded together thus for the duration of the project, then broken when the project has reached its end. The challenge here is for these actors to apply a tool that can help and simplify communications, information sharing, and perhaps the most important aspect is to create a routine for the association and the shattering of these actors. To implement such behavior using a tool such as BIM in the industry whose size perhaps is indescribable may be a very hard task. BIM (Building Information Model) could be seen as the solution to this problem because it acts as a portal where the actors involved must sign in and communicate, share information, and eventually create a behavior, a routine for this association and division of the actors following the end of the project. The technology could help the involved from the beginning of the project, already in the model stage, break down and prevent any construction barriers when the building has been placed in the works.
Humorstilar, Emotionell Perception och Kön ? Vem skrattar mest och vem skrattar sist?
The main aim of this research was to investigate four humour styles, affiliative, self-enhancing, aggressive, and self-defeating humour, and compare these with emotional perception. Forty-eight persons took part in the research, 27 women and 21 men living in the southern part of Sweden. Two humour tests were used: the Humour Scale Questionnaire ? HSQ, with 32 items, and a newly composed video test, assembled after pilot testing from 26 video clips, the Humour Video Questionnaire ? HVQ. To measure perception and interpretation of emotion, the revised version of the ?Reading the Mind in the Eyes? Test was used.

Replikering av komplexa kunskapssystem : En fråga om organisatorisk integration
Background: Many authors consider knowledge to be a significant source for competitive advantage. Replicating companies found their competitiveness on an ability to leverage its knowledge base by replicating its business model in new contexts, a process often referred to as the McDonalds approach. Several authors emphasize that an efficient method for knowledge transfer may increase the risk for imitation. Purpose: The purpose of this study is to examine in an explorative manner how strategies for replicating complex knowledge systems are employed and developed. Furthermore, our ambition is to explore the notion of replication strategy.
Svenska myndigheters användning av sociala medier : Vilka mål har myndigheterna med sitt användande av sociala medier samt hur mäter myndigheterna effekten av sitt arbete?
Swedish authorities have been dealt a mission by the Swedish state, where each agency works on the basis of their assignment. Communication has become more and more important for authorities, there are several reasons for the use of communication and they may differ from authority to authority. Some authorities claim that the purpose of the communication work is to create awareness and recognition among citizens. A communication form that has become increasingly important for government agencies is social media, according to the government authorities should implement social media in their communication work because it is very important that the authorities are available where the citizens are. Previous research has focused on the risks and opportunities that the social media generates for the public sector.
Projektering av vindkraft i turbulensintensiva områden : med fallstudie för Wallenstams planerade park vid Skuggetorp
Along with the rapid expansion of wind power in Sweden during the last decades the competition about favorable areas has hardened. This among other reasons has caused the projectors to look into development of wind power in forests. There are several aspects regarding fatigue loads on the constructions that are severe in complex terrain, among which turbulence is one. The levels of turbulence which are accepted in order for the turbines to face a life length exceeding 20 years are regulated by the International Electrotechnical Commission, (IEC). In order to keep the turbulence below these levels there are three major steering tools to use: The ambient turbulence decreases with height and can therefore be regulated by the hub height of the turbines.
Produktivitetsförbättringar : - förhöjning av produktiviteten vid mekanisk verkstad genom förkortade transportsträckor och standardiserad bearbetning
The aim of this project has been to raise the production efficiency of Daliff Precision Engineering through reduced transportation time and a more standardized manufacturing process. The problem has upraised because of a big and diversified product flora without any standard products and with just small batches ordered. The report also tries to show the work procedure with general analytical methods and be an example of how a similar problem can be resolved. The transportation time is being proposed to be reduced through a change in the layout of the factory. By moving a few manual machines, dispatch and burring to more efficient locations, the total transportation time will be reduced by 55 %.
A resource based view of productivity, firm growth and technical management tools : a case study of Swedish large-scale farms
The past and ongoing structural change in Swedish agriculture has led to an increasing
number of large-scale farms. The biological factors associated with large-scale farming
operations may cause increasing variability, risk and reduced yields due to sub-optimal timing
and management of field operations. The theory of economies of scale suggests that largescale
production may benefit from lower costs due to scale efficiencies. Thus, large-scale
farms may face cost reductions in terms of long term inputs factors, e.g. agricultural
machinery.
Virkets formförändring och dess betydelse vid postning :
The purpose of this thesis was to create a saw pattern program for the sawmill industry. I have chosen to focus on the module that describes the shrinking on the wood. There are several theories about how the wood deforms by shrinking. Several hypotheses were simulated in the program and after testing them I decided to use only one of them (hypothesis C).
The program is written in Visual Basic .NET and I choused that program language because it
is easy to do changes in the layout. Another great advantage in Visual .Net is that you can mix different languages in the same program.
Vetenskapsteoretiska och metodologiska perspektiv på tidsgeografiska visualiseringsmodeller. -En fallstudie i samhällsvetenskaplig visualisering
In the history of scientific visualization techniques there is a lack of social science practices and methodologies. The advent of modern computer graphics brought the use of visualizations into a whole new era, but even though the tools by which such modern visualizations are created become easier to access and use, the lack of social science researchers harvesting the benefits of such tools still remain. This ease of use, increase in power and accessibility plus the ever growing need within the natural sciences to augment the human senses has further complicated the relationship between scientific methodologies, validity, reliability and the use of visualization techniques. This relationship must be explored, demystified and understood in order to fully grasp the impact of visualization practices when incorporated into any given scientific method. Within the social sciences there is one example of a tradition that has since its conception carried within it a graphical notion and a visualization practice.
CMS och UX : tekniker för hur man utformar en god användarupplevelse
The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..
Resource planning for internal logistics : A tool designed for the material handling department at Scania Axles and Gearboxes
This master thesis is performed at Scania Axles and Gearboxes, a production plant located in Södertälje. Within the plant axles, gearboxes as well as central gears are assembled from components to finished products. All production is conducted on production lines, with a pre-determined rate, which is supplied with components by the material handling department. Since the production quantity and the mix of product variants produced on the production line is customer order-based, the number and type of components needed for production as well as appropriate staffing within the material handling department is difficult to predict. Scania is currently using a number of different resource planning tools for each material handling-department within Axles and Gearboxes to visualize the workload within the departments.
