Provmetod för olje- och partikelöverdrag från kompressor till tryckluftssystem

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.

Samspelseffekter vid kapacitetsförbättringar. : Exempel från Dalabanan.

The trend in the transport sector is moving towards eco-friendly, fast and convenient transportation,this results in higher demands on railway transports. To meet the demand and quality requirements,the Swedish railway network will have to expand. The cheapest way is to expand little by little butwhat impact do these small steps actually have on the capacity?This thesis examines the interactions of different improvement for the capacity on a single-trackrailway. Through simulations in the software tool RailSys this report studies what effect block signals,extra meeting stations and rebuilding existing two track passing loops to three track loops have onthe capacity.

Förbättring av utnyttjandegrad i robotcell

When a company in the manufactory industry makes costly investments, it's important that these are used as much as possible. The company in this case claims that their invested robot cell, with CNC machine isn't used enough. The questions here are: How can we improve the use of the robot cell? Which products are appropriate for the production in the robot cell? As a method to come to a conclusion, an analysis has been made over the manufactured products. And also interviews with machine operators and the production management.

Akademiska studier - En väg in på arbetsmarknaden?

Our society has become a society of knowledge. The answer to the question of how to reduce unemployment has become more and more unified: education. In this case, higher education, meaning college and university. With this disposition in our society, how does it affect the students? How does this change of society and our universities affect the students of these institutions? In this study we have chosen to examine the choices of students in universities in several Swedish cities.

Sexuellt våld hos unga - En litteraturgenomgång om unga som skadar sig genom sex och metoder för att förebygga den form av sexuellt våld

SEXUAL VIOLENCE AMONG ADOLESCENTS A literature study about adolescents who harm themselves through sex and measures to prevent that form of sexual violence Abstract Adolescents can harm themselves through sex by taking sexual risks such as sexual exposure on the internet, having unprotected sex and put themselves in situations where the potential for sexual violence is great. This type of sexual risk-behavior can create negative consequences and result in physical and mental sexual abuse. The aim of this study is to raise knowledge about youth who harm themselves through sex and measures to prevent that form of sexual violence. To accomplice this we made a general literature study on national and international research. Our study shows that despite the negative consequences, adolescent?s sexual risk-taking continues.

Beräkning av direktljud genom homogena betongväggar : Densitetens och tjocklekens påverkan på reduktionstalet

Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations we­­­re performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.

Gnosjöandans barn och deras framtidsvisioner : En studie gjord på Entekprogrammet i Gnosjö

The aim of this thesis is to study and analyze a village in the southern of Sweden called Gnosjö, which is famous for a special spirit of industrial success and entrepreneurship. Gnosjö has been successful and famous for many years but is now standing in front of several threats, like a growing number of out moving inhabitants, a low standard of education and difficulties for women to make carrier. Trying to reduce the threat of young inhabitants moving out, a new education program started three years ago with the purpose to make young students to be more interested in the technical development of the industry and make them stay in the district and hopefully be entrepreneurs.The research questions are; which consequences does ?Entekprogrammet? and the background of the students have on the students view on the spirit of Gnosjö, carrier in the local industries and wish of staying or moving from Gnosjö. Furthermore, I want to see if there are any differences between the girls and the boys, does sex have an influence on the view at the future? The study is made by qualitative and quantitative method.

Hållbar utveckling i värdekedjan

Detta är ett examensarbete inom textil produktutveckling som har sin grund hos uppdragsgivaren Bellaobastian. Syftet med rapporten är att ge en inblick i miljöarbetet i värdekedjan hos mindre konfektionsföretag, vilka svårigheter som kan förekomma och hur den hållbara utvecklingen kan effektiviseras. Vi vill ge mindre svenska konfektionsföretag råd och förslag om hur de kan uppnå en tillfredställande nivå på deras miljöarbete utan tillgång till enorma resurser.Vi har utfört intervjuer, litteraturstudier samt jämförelseanalyser mellan företagen H&M, ACNE och Lindex. Vid diskussion och analysarbetet var det tydligt att miljöarbete i värdekedjan är en komplex process och att det är flera aspekter som spelar in.Vi har kunnat identifiera åtgärder som företagen kan utföra i hopp om att uppnå en mer hållbar utveckling, både specifika som tex, materialval men även mer övergripande som att ändra sitt synsätt. Åtgärderna vi kunde påvisa kretsar kring:- Minska överkonsumtion och effektivisera resurssparandet- Minska koldioxidutsläppen- Använd miljöledningssystem och märkningar- Ändra företagets synsättEn av slutsatserna vi kunnat konstatera genom våra undersökningar är att det inte räcker med att åtgärda problemen.
