Utvärdering av Kvarnholmens silotorn inför ombyggnad till flerbostadshus

AbstractThe project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers.The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group.The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy.

Leverantörsstyrda lager på Volvo Cars Torslanda: en fallstudie om möjligheterna till en implementering och dess effekter

Detta examensarbete är utfört på Volvo Cars i Torslanda, hädanefter refererat till VCT. På Torslandaverket tillverkas bilmodellerna S80, V70, V70XC och XC90. Varje bil skräddarsys för kunden och är näst intill unik. Detta medför att antal artiklar ökar och det i sin tur leder till ökade lagernivåer. Idag har VCT problem med att det inte finns tillräckligt med lageryta och de måste finna lösningar för att reducera lagernivåer.

Miljöbilar - ett steg närmare en bättre miljö

This report concentrates on why more people do not choose an environmentally friendly car instead of a conventional car. To find this answer we have used theories that include decision - behavior and environment - philosophy. We have also made four surveys, which includes several interviews. The results of these interviews, together with the secondary data we have found, have been analyzed against the theories made by our choice. We have found that the stimulus that we have today isn?t enough to make more people choose an environmentally friendly car instead of a conventional car.

Elevers tankar om klimatförändringar

This work examines the students´ thoughts on climate change with a focus on carbondioxid through photosynthesis and the carbon emissions from cars. The study is based on two subject areas, one with a focus on enhanced greenhouse effect, and the other focusing on photosythesis. The survey was conducted by means of qualitative interviews with students in grades four and six. The results describe that student´s understanding for photosynthesis and the carbondioxids function for photosynthesis doesn´t change significantly from grade four to grade six. I have divided the students inte three levels based on their understandingof the various fields, and their use of adequate concepts.

Lane Keeping Aid : ett förarstödjande system för bilar

Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.

Småskalig elproduktion i Arvika

Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.

Arbetsutformning med syfte att skapa lärande och kvalitet

Detta examensarbete är utfört vid Volvo Cars Torslanda i Göteborg. I Torslandafabriken produceras fyra olika bilmodeller, S80, V70, XC70 och XC90, vid ett och samma monteringsflöde. Då monteringsarbetet sker vid en driven line upplever de anställda att produktionstakten är hög. Dessutom innebär de olika modellerna ett stort antal arbetsmoment. Problemet för Volvo är att nå uppsatta kvalitetsmål då det höga arbetstempot och det stora antalet arbetsmoment begränsar montörernas möjlighet till att snabbt komma upp i nödvändigt arbetstempo.

Standardiserade rapporter för underhåll av kontrollanläggning med koppling mot status för Risk och Sårbarhetsanalys

I elnätet finns skyddsfunktioner som ska säkerställa säker och effektiv frånkoppling av felbehäftade anläggningsdelar i enlighet med svensk lagstiftning, rådande normer och branschpraxis. Målet med detta examensarbete har varit att utveckla ett rapporteringssystem som hjälper till att utföra provning av elanläggningar enligt fastställda normer och samtidigt visa resultatet på ett lättförståeligt och tydligt sätt som går att använda i E.ONs risk- och sårbarhetsanalysverktyg. En risk- och sårbarhetsanalys av elnätsanläggningar krävs för att uppfylla energimarknadsinspektionens föreskrift. [1]Arbetet har utförts i fyra steg. Först har en undersökning av nuläget gjorts.

Prestanda på luftfilter : En jämförelse mellan olika filter till bil

The three models thats being tested is SAAB (93SS), VAG (1.8T) and Volvo (S60). To every brand there are three different models. A orginal- , sport- and an open cone air filter (Opti-Flow).The results indicate that the open Opti-Flow filter has better performance compared to the other cased filters. The sport filters for SAAB and Volvo has better performance then the original filter.

Energisystemanalys av ABB AB LV Motors

With a larger awareness of the climate changes and increasing electricity prices, energy efficiency measures in the industry have become more common. By rationalize the activity and by the same time decrease the emission of greenhouse gases the company can both save money and reduce negative environmental impact. For the Swedish industries the electricity price have traditional been relative low, which has resulted in a considerable larger usage than other European countries. By a deregulation of the European electricity market the electricity price will level off between the countries, which will cause a higher electricity price in Sweden than we are use to. To prevent that the Swedish industry don?t lose competitiveness against the other European countries, it will require energy efficiency activities in all different forms.ABB Sweden has decided to decrease their total energy usage with five percent in two years.

Informationshantering med kravsättning i 3D-baserade arbetsflöden

Produktframtagningsindustrin utsätts för snabba förändringar vilket medför att kraven från kunder, konkurrenter och lagkrav ökar. Företag inom produktframtagning måste därför ständigt förbättra sina metoder och processer för att fortsätta konkurrera och leverera kvalitativa produkter och tjänster. Samtidigt ska de nya metoderna vara lättarbetade, lättförståeliga och effektiva, med fokus på att minska fel, slöseri och resurser som inte skapar värde för slutkunden. Ett samordnat flöde med tvärfunktionella processer är därför önskvärt för att på ett lönsamt sätt uppnå satta mål.Med detta i åtanke fanns en uppdragsbeskrivning på Scania för att följa upp artikelritningens funktion och användning. Examensarbetet har undersökt vilka möjligheter som finns med att använda 3D-modellen som informationsbärare för att på sikt kunna ersätta artikelritningen.

Mikrofonkonfigurationer bestående av en eller två mikrofoner vid inspelning av elgitarr

This C-essay focuses its research on the taste of guitarplaying and non-guitarplaying soundengineers, in using single or dual microphone setups when recording electric guitar. It will be shown if there is a significant difference in taste when using one or two microphones between the two testsubject groups. Two classical microphone setups have been used for the test of this essay, which includes a blind listening test. The information in this test will benefit both guitarplaying and non-guitarplaying engineers by getting greater knowledge regarding what kind of microphone setups to use for different occations. The findings in this essay show in general, that guitarplaying and non-guitarplaying engineers between the ages of 19 - 26 don?t have a specific taste between single or dual microphone setups when subjected to the blind listening test..
