Lean production is the name given to Toyota?s Production System (TPS) by the west. The continuous improvements of their operations through Lean has made Toyota into the largest car manufacturer in the world. This, in turn, has led to several studies regarding both Toyota and their system as to find ways to apply Lean in other organizations. Even so, over 90 percent of all companies fail to implement Lean.

The aim of this Master's thesis is to examine what effect two different models of acquisition have on user satisfaction with information resources at academic libraries. The two models examined are the traditional model where a subject specialist librarian makes the selection, and the user-governed model where the larger part of the selection is based on user requests. The scope is the libraries of Roskilde University, which employs the traditional acquisition model and Malmö University, which employs the user-governed. Both libraries have a user-oriented approach to acquisition. The study encompasses a close examination of the acquisition policy through document analysis and interviews with the librarians in charge of acquisitions at each university, as well as a user-satisfaction survey among the professors and senior teachers on two faculties at each university respectively.

Because of among other things the globalization and a focus on core competencies knowledge has become very important for the companies of today, especially for research-intensive companies. The problem is that the companies become more sensitive to how knowledge is created and spread, that is, how organizational knowledge is created. Especially sensitive are companies who are small, young and research-intensive. The purpose with this thesis is to explore how organizational knowledge is created in small, young and research intensive companies.The theory is based on a five-phase model of organizational knowledge creation and four modes of knowledge conversion described by Nonaka and Takeuchi (1995). These concepts constitute the foundation of the analytical model used in the thesis.The study is carried out by qualitative, highly structured interviews with low standardization.

This paper aims to explore the possibility of reading the Temple cleansing stories of John and Mark through Bruce J Malina?s honor/shame model, as E. Randolph Richards do. The analysis searches in John?s and Mark?s Temple cleansings for the presence of the notions of honor and shame, as Malina uses those concepts in his model.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

This essay is about the risks of reporting science through media. We have exemplified the problems with the alarm about acryl amide that came in 2002 through the diffusionist model. From the beginning it was a debate about how dangerous acryl amide is to us humans, but later on it developed to be a debate about whoever did wrong in the intermediation, because later on it came out that acryl amide maybe didn?t cause cancer at all and the scientists didn?t know how to prove if it did or didn?t. In our essay we have based our theories about how the diffiusionist model often is inadequate, with theorists as Stuart Allan, Anders Ekström and Dorothy Nelkin..

To explore greatly varied opinion between player and reviewer, in relation to new products in ongoing digital game series, an analytic perspective is suggested, that takes the entire game series into account, instead of analyzing games (who are part of a series) as individual productions. This is explored further by introducing a model to support this perspective, based on the game theories by Katie Salen and Eric Zimmerman, as well as Gordon Calleja. This model and chosen perspective is applied against three separate cases to see whether or not it can give insight into the approach of players (of continuing game series) and the differing opinions of players and reviewers..

Problem discussion: To be competitive in a changeable environment, as the video surveillance market, in a time when the company and the market grow with almost 40% yearly, the sales organization must be well trimmed and effective. Knowledge about customers’ needs and what makes success are essential parts of the progress. Sales Product Management (Sales PM) is a new group at Axis with the main task to support local sales offices around the world in their work with different sales projects. Because of the number of ongoing projects Sales PM needs to be able to screen among these and focus on those where their help will be most valuable for the company. At the same time they have to know which kind of support their sales offices want and need.

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas. The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.

Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.

In this essay, a search strategy for citation index is studied. The strategy, which is essentially a citation cycle, starts with documents retrieved by a subject search, wherefrom new documents are identified following the network of citations backwards and forwards in time. Based on the theory of polyrepresentation, the strategy exploits overlaps between cognitively different interpretations of the same documents in order to automatically select references seed documents used as a starting point for the forward chaining. The purpose of the investigation is to evaluate the retrieval effectiveness of the search strategy and to find out whether the strategy can be used to expand a subject search with the help of the network of references in order to retrieve new relevant documents. Two questions are formulated: 1a.
