Framtagning av en utvecklingsprocess för automation - baserat på konceptet Lean Automation
Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.
Produktion av Pyrolysolja från kvistrejekt
Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting. Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to 80 %wt bio-oil can be extracted. Key parameters for fast pyrolysis are: stable reactor temperature (~500°C), short residue time for gas in the reactor (<2 s) and a very high heating rate for the biomass. Today there are several different process solutions for fast pyrolysis, where fluidized beds and rotating cones are most developed. Bio-oil has compared to fossil oil: lower heating value, low pH and also polymerizes with time. Because of this upgrading is desirable for increasing competitiveness.
Den rättsliga regleringen av avfall: Klassificeringen av avfall och den nya avfallsregleringen i enlighet med EU:s ramdirektiv
Vid tillverkningsprocesser av nya komponenter omvandlas material till antingen en produkt eller restprodukt, varpå restprodukterna hanteras som antingen biprodukt eller avfall. Oavsett karaktärisering är den genererade beståndsdelen föremål för någon form av fortsatt behandling. Vid frågan om restprodukt kan det handla om en åtgärd för avfallshantering, då substanserna saknar funktionella egenskaper för fortsatt användning. Det kan också vara så att avfallet besitter ett kommersiellt värde och kan återanvändas som en råvara i andra anläggnings- och tillverkningsprocesser eller i form av bränsle. Oavsett tillämpad åtgärd krävs tydlig lagstiftning som främjar en gynnsam utveckling och förhindrar uppkomsten av skadliga föroreningar.
Landskapsplanering ur ett hållbarhetsperspektiv :
Environmental problems are accelerating with energy consumption and the release of greenhouse gases as the major issues. This affects landscape planning mostly through environmentally hazardous transportation and heating of buildings. In environmental work, the term "Sustainable development" is often used. This term was coined in the Bruntland report in 1987. A number of frameworks have been developed to clarify the term and to remind the user about relevant aspects of sustainability.
Vilka statsfinansiella effekter erhålls vid ökad produktion av förnybar energi?
BackgroundThis paper is based on an issue raised by the organization Energigas Sverige, which together with the Ministry of Finance has posed the question about the fiscal impact of an increase in biogas production. Since the fiscal effects of an increased biogas production are both positive and negative, due to reduced use of fossil fuels, we want to investigate this further.PurposeThe purpose is to describe and explain the obtained fiscal impacts of an increased biogas production and based on our problem: ?What are the obtained fiscal effects caused by an increase in biogas production?? we could see the following fiscal effects: positive impact on employment, increased revenues of social security contributions and income taxes, reduced unemployment costs and reduced tax revenues on fossil fuels. These effects are summarized in a negative tax revenue of 2,6 billion SEK. Along the summarized negative effect we also accepted one of the two prepared hypotheses, which stated that an increase in biogas production leads to a negative fiscal impact. Design/Methodology/ApproachWe have chosen to work from an Anglo-Saxon scientific tradition and furthermore, we have a positivistic approach when we want to explain the relationship between cause and effect of an increase in biogas production and the following fiscal impacts.
En grav är mer än bara en grav... En metodutveckling av tafonomi som redskap att förstå olika anläggningar med djur
This paper deals with a taphonomic study of contexts with osteological material of dog (C. familiaris L.) from the Mesolithic and Neolithic of Sweden and Zealand, Denmark. The general aim is to develop and test a method to try to understand the activity behind and define specific archaeological structures. My questions also regards to wether a taphonomic analysis of the material could be used to identify treatments as wrapping and contraction of the dogs, but also dismembering and other preparations of the body. The study focuses on the relation between the space of decomposition, disarti-culation of the joints, evidence of wall effect, cutmarks, weathering and signs of postdepositional arrangements.The analysis is based on contexts from the materials Hornborgasjön, Vedbæk, Skateholm I and II, Sjöholmen, Ertebølle, Bökeberg, Bredasten, Löddesborg, Bergsvägen and Röekillorna, dating from early Maglemose culture to Neolithic Battle axe culture.The analysis shows that a closer study of taphonomic processes can be used to identify different structures as graves, offerings, religious and non religious contexts or parts of animals, probably put into the ground as waste.
Läs mig : Att omarbeta längre texter ur dagstidningen för webben
Most swedish newspapers have a homepage where their news are presented. Existing guidelines describing how to write for the web often recommends you to keep it short and stay objective. But how about longer pieces of content presented in the print version? What will become of reports, interviews and essays as we?ve come to know them as the printed newspaper goes digital?Interviews with representatives of five swedish newspapers shows that the extent to wich content is being published on the web is connected to the overall purpose of the web presence. The fact that many newspapers does not publish longer pieces of text on the web rather seems to be an economic issue, than a matter of good readability.Past studies shows that longer pieces of text may well work on the web, if the reader?s interest is big enough.
Tillämpning av utvärdering inom operativt förbättringsarbete
In the fall of 2014 a literature review and a scientific study of the topic; "... in the extent to which companies in the industry applies the evaluation of continuous improvement? was conducted at Mälardalen University. These studies are the foundation of this thesis.A strategic improvement is often divided into smaller steps of improvements at each hierarchical level from the top down through the organization. But if there is no response system that can confirm the results of these improvements back through the organization it is very hard to see if the improvements really are improvements or just changes and a waste of resources.
Förutsättningar och hinder för att minska elektronikavfall : En studie över hur WEEE-direktivet påverkar Sveriges förebyggande åtgärder mot elektronikavfall
To meet the growing amount of waste from electronic and electrical equipment (WEEE) EU developed, year 2002, a directive (2002/96/EG) with the objective to govern the management and reduce the amount of WEEE. The directive is based on producer responsibility which makes the producer responsible for collection and dispose of WEEE. In 2012 a new revised directive (2012/19/EU), with tougher collection targets, was developed. Both the old and the new directive states that the approach to tackle WEEE should be prioritized in order of prevention, reuse and then recycling. Hitherto the amounts of WEEE has increased every year, making it relevant to examine which type of preventive measures the directive contains and how effective they are.
Framtagning och miljömärkning av kvicksilverfri xenonstrålkastare
The project this report is handling has been implemented on NBB, Nordisk Bilbelysning AB in Linköping. The company produces and develops lightning and searchlights for all types of vehicles. Lately NBB´s supplier of electronics, OSRAM, has developed a mercuryfree xenon lightsource. Mercury is one of the most hazardous environmental waste and to get rid of the mercury entirely in the lightsource is a big step that means alot for the environment.This lightsource will be placed in one of NBB´s worksearchlights called My, and will be sold as an alternative to mercurycontaining searchlights. NBB wants to put an environmental label on this product and they want to have essential information about the product that is needed for the production.
Kalvningsförlamning
Every year, thousands tons of edible food are discarded by the grocery stores. This is food that could have gone to people that?s in need of it. In many countries, so called food banks are established in order to supply welfare organizations with this kind of food. Today there is no equivalent system existing in Sweden.
En miljo?ja?mfo?relse av traditionellt stambyte kontra relining av tappvattenro?r : Med hja?lp av livscykelanalys
This study was a final thesis, for the bachelor program in civil engineering at theUniversity of Uppsala, which was made on behalf of Riksbyggen in Uppsala. Acomparative study of two stain renovation methods; tradition pipe replacement andrelining was done with an environmental perspective. A simplified life cycleassessment (LCA) was done according to the International Organization ofStandardization (ISO) with the LCA tool Eco-indicator 99, in order to be estimate theimpact on the environment. LCA is a method that follows a product or a system?from the cradle to the grave?, which means that all the environmental impact over alifetime is considered.The work was executed by using a stairway with nine apartments in a house called?Uppsala Hus 9? as a reference object, which was provided by Riksbyggen.
