Is it possible to conduct a joint organizational change despite different circumstances and different starting points, and still talk about the same organizational change? Can all the work that leads to more efficient operations fall into the same category? How can such concept gain legitimacy? The result shows that by talking about a concept, in this case, Lean, as something that leads to a better and more efficient organization, without for that matter have to set a defined content of the concept you still can present the process as one concept. Tough the concept will be practically blank. But there is still a rhetorical value in the concept of Lean. The organization institutionalizes the concept and obtains in this way legitimacy from its surroundings.

This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.

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.

The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

Promoters are genetic elements that facilitate the transcription of a gene and they have been found in front of non-coding RNA (ncRNA) genes in different organ-isms, e.g. the model plant Arabidopsis thaliana. A similar element, DUSE, has been found in front of ncRNAs in the social amoeba Dictyostelium discoideum and a part of this project has been to analyze the function of this putative promoter element through cloning and expression studies. A construct to analyze the func-tion of DUSE was successfully designed and introduced into D. discoideum but full expression studies were not finished because of shortage of time.

Thermal fatigue is a serious problem in todays power plants. A large amount of damages around the world circles around that subject. The damage can come from the mechanism of two flows mixing with different temperatures in a T-junction. It is a fundamental prerequisite that these T-junctions are frequently tested for damages. An amount of criterias steers the rate of testings.

Purpose: We wish to gain a deep knowledge about product development processes in relation to the aspect of time in companies in highly technological and rapidly changing markets. The purpose is to establish how organizations better can employ time as a resource to make the product development process more efficient. Conclusions: Information we gathered from theory and primary data show that information flow, synchronization and time profit when seeing time in three dimensions are factors which should be reflected in the architecture of a product development process. To illustrate our findings, we decided to create a model..

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems. Based on the needs we have found in our fieldwork, we have been looking at possibilities to make multi user solutions with the sensor..

Increased energy consumption in the world has created an increased supply of various fuels, especially fossil fuels. The Swedish government has set up various energy targets for 2020. To reach these goals it?s important to increase the energy efficiency in local buildings such as schools. This work illustrates the breakdown between energy supply and energy losses over the school.

A sample of milk inoculated with S. aureus was treated with penicillin, and Antipen (a new commercial product containing penicillinase) was added. To another sample with S. aureus and penicillin, formic acid to pH 5 was added, and to yet another sample, a combination of formic acid and Antipen was added. Controls with no penicillin were treated in the same way.

Optioner är ett instrument som investerare kan använda för att spekulera i framtida upp-eller nedgångar på olika tillgångar. Om dessa optioner är felprissatta finns det möjlighet att göra riskfria vinster med hjälp av Stolls köp-säljparitet. Tidigare studier visar att marknaden inte alltid är effektiv i sin prissättning av aktieindexoptioner och att det därigenom finns möjlighet till arbitrage. Denna studie undersöker huruvida marknaden är effektiv i sin prissättning av VINX30 aktieindexoptioner, d.v.s. finns det möjlighet till arbitrag på VINX30 aktieindexoptioner?.

This is a graduate work at the Swedish University of Agricultural Sciences, The Department of Urban and Rural Development, Ultuna. The purpose of this paper has been to find out and describe principles for designing parks that offers good recreational and aesthetical values and require little amount of carbon dioxide emissions during their maintenance. The purpose has also been to see if it's possible to use city wastewater in some extent to assure the plants water supply and to find other means to make it less necessary to use purified water for watering. Recently made studies as well as older ones show how important green areas are in dense city structures both from a health and a climate perspective. Trees and other plants adsorbs different forms of air pollution and can also lower the temperature in the surrounding area through their transpiration.
