Processer och metoder som möjliggör för en effektiv produktframtagning
The high level of competition and the rapidly growing technology development has created new challenges for today's businesses where they are forced to deliver more customized products at a lower price and a shorter time period. This places high demands on the companies' ability to design and develop better products in a more efficient way. In addition to developing products, the design process focuses on securing long-term success for the company by developing nourishing skills. However, to achieve an effective design process the companies must improve their ability to plan as well as use their knowledge base in a more efficient manner. Toyota's product development system is a critical component for companies to address challenges that they?re facing and offers a great potential to create significant competitive advantages.
Programvarustöd för hot-, risk- och sårbarhetsanalys
This report describes a final thesis done during the spring of 2008 as part of the bachelor degree in computer engineering degree at the School of Engineering in Jönköping.The client is working in the consulting business and is involved in, amongst others, work regarding information security. Within this field they perform so called Threat, Risk and Vulnerability assessments. Today these assessments are done by a predefined method, but many details are controlled by the person documenting the project. A wish was made that the implementation was standardized, it should also ease the task of estimating the need for time and money. The solution for this seems to be a software tool.
Utveckling av provmetodik för HVAC på lastbil : Klimatprovning i klimatvindtunneln CD7
The issue about how Scania shall perform HVAC tests in the climatic wind tunnel CD7, which Scania is about to complete by year 2013, has resulted in four test methods for truck HVAC and also a test method structure. The test methods have been chosen to focus on sun, snow and rain simulations. These are adapted and developed according to what should be tested and to what can be tested in CD7, which has been the object. With CD7 different climates can be simulated in a controlled environment for complete truck level, from desert with high sun load to arctic cold and snow.The test methods represents a basis to start from, for designers and test engineers which make the testing more repetitive as well as time eventually can be saved. Before the test methods can be applied they must be verified as they are based on theoretical and empirical assumptions.

Bonusföräldraskapets många ansikten : en kvalitativ studie av roller och rollskapandet bland bonusföräldrar
The aim of our study is to examine stepparents´experiences of their role in the new family, we also want to examine if the role as stepparent is affected to the role as a biological parent. Our study is based on six semi-structured interviews, with three stepmothers and three stepfathers.By using role theory and symbolic interactionism our results indicate the requirement of constant negotiation as well as acknowledging the need to consider the other familymembers, those you may not have chosen to live with.We can see that the division of responsibility is governed by what is best for the family - to make life as easy as possible. It is clear that many stepparent lack guidance in what is expected of them in their new role; howeverr, they have been able to grow into it. .
"Om jag tänker efter så läser jag nog mer än jag tror" läs- och biblioteksvanor bland pojkar på gymnasieskolans fordonsprogram samt deras uppfattning om bibliotek
This master thesis deals with reading and library habits among young male students at the vehicle engineering programme in an upper secondary school. Also their overall opinion of libraries has been looked into. For the completion of this study all of the 43 students in question took part in a questionnaire while 5 of them were interviewed. The result of this statistical survey complemented with more focused interviews show that at some time or another all the students read, but their preference lies within the news and engineering pages of daily newspapers and periodicals. Those who read books choose action and fantasy for content.

En förbättrad rullstolsplats på klass 1 bussar : I sammarbete med Benteler Engineering Services
The initiative for this project was taken by Benteler Engineering Services, as a result of having identified areas of improvement, in designated accessible areas like the wheelchair spot onboard buses. Depending on a wheelchair to be able to move around can understandably be challenging.Public transport is a common good in today`s society, however despite the measures taken towards adjusting to accessible needs, the majority of those being disabled chose different alternatives of transportation. This is due to reasons such as the drivers' poor attitude, furthermore the limitations of the space allocated to accessible needs, as people with strollers also use these spots onboard. Also, some wheelchair users find the rides unsafe, as they could easily fall over during without the appropriate space for them onboard the buses etc. These are only a few reasons why other options are sought out, i.e.
Industrialisering av konsumentprodukt : Från inkommande material till färdigvarulager
This report examines the industrialization of a newly developed household machine on behalf of Technogarden Engineering Resources in Karlstad, Sweden. The report is a part of the final course in the Bachelor Program in Mechanical Engineering at Karlstad University and takes place in spring 2014.An innovator, an investor and a engineering consultant firm have through collaboration developed a new type of gruel machine. The product is in its final stage of construction and is planned to be manufactured in a production located in Sweden, autumn of 2014.To compete against today?s trend in outsourcing manufacturing to low cost countries for better profitability, the industrialization of the gruel machine must be done with a minimum amount of resources in order to become successful, which also describes the problem of this study. Using pre-study material in form of Lean production literature, visiting a successful production site and gathering data from involved engineers a specification was developed which describes what this industrialization must achieve and which requests can be accomplished.

REDOGÖRELSE FÖR SPRICKARMERING FÖR KONSEKVENT DRAGNA BETONGPLATTOR PÅ MARK : Analys av skillnader mellan BBK 04 och Eurokod 2 med tillämpning av svenskt och danskt nationellt annex
In this diploma work the approach of determining the required amount of reinforcement in slabs exposed to pure tension is processed, on behalf of Ramböll Uppsala. It is a well-known problem in the industry that there are uncertainties in the determining of the amount of crack reinforcement, especially for structures exposed to pure tension. Cracking caused during the time of dehydration in concrete slabs is the most common defect according to statistics made by CBI[1], which provides numbers as high as 35 % of all the defects caused on slabs are generated by cracks. Comparisons between Sweden's former national standard BBK 04, Building Regulations for concrete structures due to restrained forces of shrinkage, and the current European standard Eurocode 2 are carried out through theoretical studies and concludes with several examples of calculations. Rigorous calculations of both standards, BBK 04 and Eurocode 2 with application of the national annex in Sweden and Denmark are performed.
Selenium in Swedish sheep production
Selenium (Se) is an essential trace element that is involved in several physiological functions in mammals. Mostly, Se is bound to proteins, many of them with enzymatic functions. A group of seleno-depending enzymes, glutathione peroxidases (GSH-Px?s), are important as antioxidants and protects against free radicals. The activity of GSH-Px is strongly regulated by Se storage in the liver.

Production system mapping for product design
Detta examensarbete är resultatet av en utredning av produktionsbegränsningar och produktutveckling på Volvo Construction Equipment AB Component Division i Eskilstuna. Produktionssystemet på Volvo CE genomgår en stor förändring då det går från att fungera som en funktionell verkstad till att bli flödesinriktat. Detta gör att helt nya krav ställs på produkternas konstruktion och utformning. Det är nu inte möjligt att anpassa maskinerna eller operationsföljderna efter artikeln i samma utsträckning som tidigare, man kommer att vara tvungen att anpassa artiklarna efter produktionslinan. Därav har en litteraturstudie inom Concurrent Engineering gjorts som belyser hur man bör jobba som organisation och vilka verktyg man har till sitt förfogande, för att utveckla produktionsvänliga produkter.
