Infallsvinklar och angreppssa?tt fo?r en svensk livsmedelsstrategi : En utredning av angreppspunkter och betraktelsesa?tt hos livsmedelsstrategi-intressenter samt ha?llbarhetsaspekter av dessa.

Understensho?jden is Stockholm's largest eco-village which was built in the early 1990s with the vision of enabling ecological living for people. However the ecovillage is no longer considered as environmentally friendly because of its relatively high energy consumption, and non-updated energy system. The purpose of this study is therefore to investigate how Understensho?jden should reduce their energy consumption and upgrade its energy system by using Blower-Door, IR-camera and Design Builder.

Man blir påverkad av sitt kön vare sig man vill eller inte : En kvalitativ studie om skillnader i män och kvinnors musikpreferenser

Music has always been an important form of communication and it can be found in many different contexts including aesthetical, cultural and emotional forms. In the globalized society of today music can be distributed fast through radio, TV, CD: s and the Internet. For many people consumption of music is an important part of the daily life and it can contribute to shape an individual?s attitudes and personality.The main purpose of this study is to find out whether there are any differences between men and women?s musical preferences. I will apply an explorative approach using qualitative interviews to describe what causes the differences.

Erosionsskydd i strandzoner :

Erosion in coastal areas is a common problem all around the world. The range of the problem depends on several factors, i.e. type of bed-rock and soil, wind and wave climate. Another factor is whether the area is of high interest, i.e. if the area is important for tourism and recreation, if there are houses and other buildings close to the shoreline or if it is a site of special scientific interest.

Livscykelanalys av flerbostadshus ? energieffektiviseringsåtgärder för minskade koldioxidutsläpp

The importance of energy- and environmental issues has increased, and the work towards reducing carbon dioxide emissions plays a major part. The European Union has set up goals for the membership countries to work towards this to happen. The carbon dioxide emissions in Sweden have been reduced the last few years, but there is still a lot to do. About 30 per cent of Sweden?s carbon dioxide emissions generate from energy usage related to housing, this is why the housing sector is of interest to examine.

Key Success Factors i projekt inom Entertainment, En fallstudie av HippHipp! [paw rihk-titt]

Syftet är att beskriva ett projekt inom Entertainment och identifiera dess Key Success Factors. En fallstudie gjordes av privatteaterproduktionen HippHipp! [paw rihk-titt] som gavs i Lund 2003-2004. I en induktiv studie genomfördes nio stycken intervjuer som resulterade i ett empiriskt material. Detta material analyserades och relaterades till teorier om projektledning (Briner m fl), adhocrati (Mintzberg), Key Success Factors (Grant) och Experience Economy (Pine & Gilmore). Studien beskriver ett framgångsrikt projekt inom Entertainment och förklarar framgången med projektet genom att presentera sex stycken Key Success Factors.

Inventering och bedömning av förorenade områden inom division Energi, Tekniska Verken i Linköping

This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.

Stopptids- och avvikelseuppfo?ljning vid la?nga takttider : Fra?n avvikelse till info?rd fo?rba?ttring

High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.

Porträtt av personer med funktionsnedsättningar : - En kvantitativ och kvalitativ undersökning om den bild SVT:s respektive TV4:s nyhetsinslag skapar av personer med funktionsnedsättningar

The study has answered the questions to what extent people with disabilities are involved in SVT- and TV4- news reports and how people with disabilities are represented in news reports. The material is based on 140 news items.The study has demonstrated that news reports SVT and TV4 have different grades of misconceptions about disabled people. Disabled people are constantly being reinforced by negative disabling terms, the disability being of central importance for the news broadcast and they still occur in stereotypical depictions. Through the image of disabled people forms the bed-rock on which the attitudes towards, assumptions and expectations of disabled people are based on. They are fundamental to discrimination and exploitation that people with disabilities face on a daily basis, and contributes significantly to their systematic exclusion from mainstream society.

Underlag för bedömning av energibrunnar inom vattenskyddsområde

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.

Smarta lokala energisystem, Vision-Teknik-Tillämpning

The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.

Effektmätning i pump

The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.

Vibrationsisolering av gruvmaskinshytt

Detta examensarbete, på uppdrag av Atlas Copco Rock Drills AB, syftar till att kartlägga de problem gällande vibrationer som finns och uppstår vid användandet av produkten Scaletec MC och komma med förslag till lösningar på ett nytt system som bättre hanterar vibrationer än det befintliga. Lösningarna är avgränsade till hytten och hyttens koppling mot ramen. Kartläggningen av Scaletec MC visade att den största problemskaparen är den långa bommen med den tunga hydraulhammaren framtill. Den skapar rörelse i hytten både vid skrotning och vid transport. Vid transport är även den odämpade stolen, de ojämna vägarna och det faktum att axlarna är stela ett stort problem som genererar helkroppsvibrationer hos operatören.
