Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.

In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

The aim of this thesis is to examine the flow of information in an administration of the municipality Borås Stad. To achieve the aim the following questions were asked: How accessible is information? How is information used in the organisation? How is information communicated? Totally sixteen qualitative interviews was accomplished with employees at the administration. The results of the interviews show that there is a difference in how much and what sort of information the respondents use. They all seem to prefer information to be communicated face to face if possible or over the phone.

From the customer?s perspective the only reason for a firm to exist is the value it creates. However, a problem within manufacturing companies is that of the total lead time, only a small part can be considered as value adding. It has further been discovered that when working with improvements businesses often sub-optimizes single processes instead of considering what benefits the entire company. Thus, when improving processes and activities it is important to have knowledge about and understand which factors that affect how the flow can be designed.Several studies have been performed with a wide perspective on process flows in order to obtain a more resource-efficient and value added flow.

The thesis has been carried out in cooperation with Master Flow AB, Västervik owned by the EWEBE Group. The company produces and sells hot runner systems that are tailor made for the customers.The problem that MasterFlow AB has encountered is in the construction of complex hot runner systems in SolidWorks. With several different lengths, fronts and endcaps that builds the nozzles of the hot runner systems, is affecting the problems for MasterFlow AB. The purpose of this work is to automate the design of hot runner systems so it does not overload the CAD-system SolidWorks.To gain an understanding of the problem, there have been several studies and observations at the company, where the focus has been on how the work is done with the design of hot runner systems. By using help from the corporate management, enough information has been collected to find a solution to these problems.The implementation of design automation has been based on a flowchart that was created.

The research objective of this thesis was to conduct a holistic evaluation of an operational information system. By holistic evaluation we mean that an equal focus was placed on both the system system perspective and its users user perspective, in the actual environment where the system and its users function contextuality. In addition, the methodological objective of the study was to test a new research approach in a real life setting. The participants of the study were twenty newspaper journalists employed at Göteborgs-Posten GP. The information system NewsLink is a manually indexed full-text database containing all articles published in GP since 1994.

In cooperation with the Gislaved company Lerocon AB [1], a separation module wasdesigned as a further supplement to the Module System. The aim of theprojectimplementation was that the separation module could be flexible enough to feed themetal pieces, screws, nuts and other items with large variations of size, appearance andmaterial composition. The module should also be cost effective to manufacture.A separation module is a design which is ment to streamline the work in industries withautomation of the lineoperations. The module feeds the details such as screws, nuts, washersand pieces of metal in a continuous flow in which traps separate the details from each other.Traps may vary depending on the purpose and of the details that are fed. Perhaps it isimportant for the user that the detail-orientation is right after the separation module, whichmeans that all the pieces witch aren´t are fed back in return.For companies and industries in lineoperations that can be made more efficient withautomation, are production flow an important watchword.

In a global economy it is important to understand what project management is and how it functions in a contemporary company. This report includes an empirical case study of a project flow, which was conducted in the department Packaging Concept (PC) which is a part of Stora Enso. As all of PC´s customer enquiries are unique and must be considered an individual project, PC continuously works in projects. An analysis of the project flow was conducted based on interviews at and visits to PC as well as relevant documents distributed by the department. The report gives an understanding and analysis of how PC works in projects.

The effects of the deregulation of the electricity market 1996 in Sweden on short-term hydropower regulation are unknown. This report investigates patterns in subdaily regulation in the Ångerman River Basin during the period 1993-2011. Differences in subdaily flows and zero flow events between the periods 1993-1995 and 1996-2011 were studied by analyzing hourly data from 8 regulated and 8 unregulated locations with four subdaily flow variation indices. No correlations between the market deregulation and the regulation intensity in the Ångerman River basin were detected. The number of days natural ranges of variability were exceeded and the magnitude of subdaily variation were significantly higher at regulated locations.

The purpose of this study was to examine whether an inventory of the vegetation overgrowth could be used to indicate a locally nutritional impact. The study was conducted at Märstaån where the water runs through a number of agricultural lands that could lead to an increased amount of diffuse emissions of nutrients. The vegetation overgrowth in the water was also studied in relation to shade, meandering and water flow effects on the vegetation. With this method, no definitive conclusions could be drawn.Where the water was shaded, no vegetation overgrowth could be found. Therefor trees should be planted to prevent any future overgrowths.

I denna studie är syftet att belysa vilka effekter som underhållningsspel kan ha på motivation och koncentration samt även undersöka om spel kan användas för att förbättra den kognitiva prestationen. Konkret ställs frågan vilka förändringar som sker i reaktion, korttidsminne och perception efter att ha spelat Gradius 3 samt vilka orsaker som ligger bakom dessa förändringar. Resultatet pekar entydigt mot att spelandet har en positiv effekt och förbättrar den kognitiva förmågan. Särskilt när det går bra i spelet och man får ett flow kan prestationen maximeras, vilket överensstämmer med Csíkszentmihályis flowteori. Det flow som uppstår i spelet ger en euforisk känsla av tillfredsställelse som stimulerar motivation och koncentration, vilka båda är förutsättningar för bättre prestation.

This thesis is a feasibility study into how Fresenius Kabi may rationalize their destruction process in regards to cost, recycling, and work environment. The two main objectives are to identify scrap flows and the possibility to improve or replace the equipment that is now carrying out the physical scrapping. The flow has been visualized by a flow chart of the material and communication. A chart of the problem established to visualize where improvements are necessary. Based on the problems proposals are presented on how to improve the flow thru the plant.During analyze of the physical scrapping equipment it was also necessary to take a deeper look at how they are carrying out there work today, how does the procedure look like, working environment and where are the weaknesses.

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

Increased competition in the IT industry has sparked a need for developing faster innovation processes with more predictable output. One of the biggest issues when it comes to achieving a faster flow through the innovation process lies in managing its high degree of variation. Proposing a solution to this problem, Lean Software Development (LSD), was developed to provide a framework for how IT companies should organize its software development process to achieve increased speed and quality. This study examines to which extent LSD, as a set of values, principles, methods and tools, can be used to improve flow efficiency in the innovation process. A case study of a multinational IT company was made by conducting ten semi-structured interviews with current employees.
