Processanalys av Scanias mjukvaruutveckling för drivlinan
Scanias nuvarande mjukvaruprocess upplevs, i många fall, vara onödigt lång från det att en idé har genererats tills att den har lanserats på marknaden. För att konkurrera på marknaden är det viktigt att erbjuda nya tjänster och ny avancerad fordonsstyrning som snabbt ska kunna sättas i produktion. För att säkerställa att mjukvaran uppfyller de uppsatta kvalitet- och säkerhetskraven används inarbetade processer däribland den så kalladeEmbedded Release Process. Dock är denna process inte alltid till hjälp för utvecklingen och kan medföra lång "time-to-market".Syftet med detta examensarbete var att utreda Scanias nuvarande utvecklingsprocess av mjukvara med avseende på ledtider, eftersom det idag råder frågetecken om huruvida processen är tidsmässigt optimerad från idé tills att den når kund.De metoder som har använts för att angripa de uppställda frågeställningarna har bestått mestadels av kvalitativa forskningsmetoder så som litteraturstudie, värdeflödesanalys, fallstudie, benchmarking samt workshop. Såsom ett komplement till den kvalitativa forskningen har statistik tillämpats i fallstudien.Värdeflödesanalysen visade på många överlämningar inom organisationen, centraliserad beslutsfattning samt att flödet sker sekventiellt.
Vindkraftens framtida scenarier
In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.
Kemisk karaktärisering samt nedbrytning av process- och avloppsvatten vid SCA Ortvikens pappersbruk
During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.
Förändringsarbete i skolan - med lean som inspiration : Lean-tavla - för röd tråds skull!
During the middle of the 18th century the development of Toyota Production System, TPS, started in order to streamline the processes. TPS was based on the principles of assembly line production but unlike previous performers Toyota let the manufacturing be constantly affected by demand. At the end of the 18th century TPS was described by Womack and Jones in the book "The machine that changed the world - the story of lean producion" where TPS got the name lean. The principles behind lean is to maximize customer value and eliminate waste which means making products and services more valuable to the customer. 1Lean was for a long time a philosophy and an approach limited to industries and production based companies.
Inventering och riskklassning av förorenade områden i Öna och Östnor :
This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.
Fuktkvotens inverkan på oljeupptag och pigmentinträngning i tall (Pinus sylvestris L.) och gran (Picea abies L. Karst) vid impregnering med Linotechmetoden :
Wood has always been an important material for people, and it is used for many applications. As for example, fuel for cooking and heating houses, construction materials and for constructing means of transport. Since wood also is a material that with time biologically degrades due to activity by micro organisms and wood fungi it is important to find ways to protect and further lengthen the life span of the material when in service. One method is to decrease the amount of water in the material by impregnation with an hydrophobic oil. The Linotech method which uses only pure linseed oil is one such possible method.
The aim of this study was to investigate the possibility to at the same time impregnate and stain/colour wood samples of pine and spruce by using the Linotech method.
Bygglovsbefriad vindkraft till småhuset : -Ur ett tekniskt och ekonomiskt perspektiv
In connection with the property crises in many countries, caused by the financial crises, people are now more aware of the risks involved in poor property-investments. The unusually cold winters along with extreme prices of electricity in Sweden in recent years has also contributed to increased interest in energy-efficient buildings.The process of developing a modern family home in Kiruna, Sweden is presented the first part of this paper. The house has been designed to withstand very high stresses from snow, low energy consumption as well as a high standard of living comfort. Aspects of the house covered here involves everything from construction, heating and ventilation to sanitation. Each of these areas is presented based on their underlying, scientific methods or theories.
Landskapsarkitektens yrkesroll i Sverige och Spanien : en jämförelsestudie mellan svensk och spansk landskapsarkitektur med platsexempel från Stockholm och Barcelona
Landscape architect is a profession that withholds varying tasks inside countries and between countries. In many countries the landscape architect profession does not exist. Spain is a country where the landscape architect profession is not recognized, and the professions that work with landscape architecture are architects, engineers, biologists and agronomists. "Paisajista", in English "Landscaper," is in Spain a common name for those who design gardens and parks. Sweden is one of the countries with most landscape architects due to its population and the profession is well established.
Miljöbedömning samt kartläggning av verksamhetsavfall som del av Uppsala kommuns avfallsplan 2014 ? 2022
I början av 1900-talet slängde svensken i genomsnitt 25 kg hushållsavfall per år. Idag är siffran 500 kg. Trender pekar på att avfallsmängderna kommer att fortsätta öka. 95 % av det genererade avfallet i Sverige kommer från verksamheter. På nationell nivå finns riktlinjer och miljömål kring avfall, men för att implementera många av dessa styrmedel krävs lokala incitament.
Inhysningssystem för kalvar och ungdjur i större besättningar :
In Sweden, there has been a continuous increase in the volume of housing construction for
dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.
"Lite Svinn får man räkna med" : En kvalitativ studie om upplevelser och tankar om matsvinn hos chefer och personal i livsmedelsbutik
SammanfattningBakgrund Att minska matsvinnet är en viktig del i arbetet mot att nå en hållbar utveckling. Utsläpp av växthusgaser och övergödning sker i alla produktionsled i livsmedelskedjan från producent till konsument och utgör en negativ klimatpåverkan. Livsmedelsbutiker har en betydelsefull roll eftersom de hanterar stora mängder varor och tillhandahåller mat till många hushåll. Forskning finns om typ och omfattning av matsvinn slänger men få studier har belyst hur chefer och personal i livsmedelsbutik upplever och tänker kring ämnet.Syfte Syftet var att undersöka upplevelser och tankar kring matsvinn hos butikschefer samt anställda i livsmedelsbutiker.Metod Studien genomfördes som en kvalitativ studie där butikschefer och anställda vid åtta livsmedelsbutiker intervjuades. Datamaterialet transkriberades och analyserades därefter med kvalitativ innehållsanalys enligt Graneheim och Lundman.Resultat ?Matsvinn sågs som ett problemområde som deltagarna upplevde svårt att motverka.
Möjligheter och hinder för att utöka omfattningen av RoHS-direktivet
The RoHS Directive was introduced in order to restrict hazardous substances in Electrical and Electronic Equipment, EEE. It currently restricts the use of six hazardous substances/compounds; cadmium, lead, mercury, hexavalent chromium, PBB, and PBDE. The RoHS Directive currently includes category 1-7 and 10 in the categories of EEE listed in Annex 1A to the WEEE-Directive (Waste of EEE). The aim with the report is to investigate and elucidate prospects and obstacles to increase the scope of RoHS. This report mainly considers the inclusion of product categories 8 (Medical Devices) and 9 (Monitoring and Control Instruments).

Inventering av förorenad mark på LKAB´s industriområden i Kiruna, Svappavaara och Malmberget :
The county administration asked LKAB to make an inventory of possibly contaminated sites
caused by their mining activity. The inventory should be performed according to the MIFO
model, a method from SEPA which is used to assess a contaminated site. The first phase
involves collection of information through interviews and site inspections and in phase 2 a general survey with field sampling is conducted.
LKAB started the work with the first phase of the survey during 2003. During this project the information collected in Phase 1 was evaluated and 16 of the sites were chosen to proceed to MIFO Phase 2 (six sites in Kiruna, and 5 sites respectively in Svappavaara and Malmberget). The sampling of these 16 sites was performed during week 27 2004.
