Simulation driven design of optimized sheet metal bracket

Det ständigt ökande trycket på minskande utsläpp och effektivare energianvändning driver utvecklingen av Scanias produkter. För att varakonkurrenskraftiga på marknaden behöver man leverera lastbilar med högre kvalitet och lägre bränsleförbrukning, det vill säga sänka transportkostnaderna förkunden. Ett steg i detta är att utveckla komponenter i fordonet som är optimerade iförsta hand med avseende på hållfasthet men även mot vikt och pris. En betydande andel av lastbilens komponenter är plåtfästen som ofta underprioriteras i produktutvecklingen. Examensarbetet fokuserade därför på att utveckla metoder för konstruktion av plåtfästen.En metod för att förbättra konstruktionerna är att arbeta med simuleringsdriven konstruktion.

Allt är möjligt hus i Gustavsberg

In a sequence described in the next paragraphs, I remove the poorly insulated roof of Gustavsberg Porcelain Factory and make new use of its  foundation. The monolith cement slab, once supporting heavy industrial machinery, is now the site of lakes and other movements:The top floor area is split, and a new built volume, one story higher, overtakes the southern half resting on the factory?s basement, digging into it at its western and eastern ends. Striking horizontally, the fissure exposes a long central axis, taking advantage of the factory?s horizontality to articulate vastness .

Materialhantering till och från robot

Material handling is a term that includes all kinds of handling of material from a raw product to a finished one. ABB is active in the following segments; foundry, packaging and palletizing, metal industry and plastics industry.The demands for efficiency and reliability have been set very high in the industrial sector. Optimizing of the material handling will give the company higher cost-effectiveness. Around the robot there are different kinds of material flows, to optimize the cycle time, consisting of carriages combined in different ways.Motion Control is a complex system with main functions such as; positioning, synchronizing, indexing and more. The products in the system need to cooperate to make these functions possible therefore integration of motor- and servo products are important.

Lost in Identity : - A case study of three jewellery practices andhow they can function as codes of identity

During a major part of modernity the concept of identity was something that in many ways was predetermined for the individual. People in general remained in the same social spheres as the generations before, shared common religions and beliefs and where more or less bound to a geographic area. Identity and lifestyle was something that was adapted quite unreflected from habit and tradition. Though, during the cultural modernisation process that took place in the twentieth century, previous shared patterns of interpretation vanished and became individual.  Finding references, constructing an identity and establishing a self became individual.

Tvång som vård : Patienters upplevelser av tvångsvård och tvångsåtgärder ? en litteraturöversikt

Background For patients in need for psychiatric care who refuse treatment, coercive care might be necessary due to The Law of Psychiatric Compulsory Care, LPT. The purpose of this law is to make sure the patient later on will be able to increase autonomy. The most frequent patients in coercive care suffer from psychosis, heavy depression or having high risk of committing suicide. One of the most important tasks in the nurse profession is to increase patients? autonomy.

Studie av en medeltida husgrund : en analys av bronsfynd från husgrund 6, Västergarn, Gotland

This essay is an analysis of the objects made of bronze found in an excavation Västergarn parish, Gotland, in 2010, conducted by the University of Gotland. The studied material presented in this essay comes from contexts inside, as well as nearby the foundation of a medieval building which purpose is still not certain. The first purpose of this study is to present the bronze-objects found inside and nearby the foundation of house 6, and to see if there are any datable objects. There is also a discussion whether there has been any bronze-crafting in the area. The second purpose is to make a contextual analysis to see if there are any differences between the material found outside and inside of the building, and what conclusions can be made regarding the function and use of the building.

Den psykosociala arbetsmiljöregleringen : Med inriktning på arbetsrelaterad stress

This essay focus on work related stress and psychosocial enviroment in working life. The purpose of this study is to present a detailed description of regulation of the the Occupational Safety and Health Act and investigate how well employees are being protected by the law.I will also explain with the help of statistic which employees that most often suffer from work related stress and the results is discussed from a gender perspective.Work related phycosocial health is a big issue in todays workplaces, and people who suffers from stress are supposed to be protecteded by the the Occupational Safety and Health Act, but is that really the truth? The Occupational Safety and Health Act is a frame law, meaning the law is general and needs binding regulations to define the rules, and there is no such act about work related stress at the moment. No employer has ever been convicted for work related stress. At the same time the Occupational Safety and Health Act explains that the employer has a responsibility to take arrangement to prevent mental illness in working life.It?s mostly women who suffer from work related stress.

Lufttäta byggnader

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

Samsjuklighet och förbättring : En kvantitativ studie om personer med missbruk och samtidig svår psykisk störning på Södermalm i Stockholm

The purpose of this paper was to examine how clients on the unit for adults at Södemalms district administration (Stockholm, Sweden) with severe mental illness and substance abuse differs from other clients with substance abuse at the baseline and at follow-up one year later. We have used a quantitative method and analyzed material from ASI-interviews performed at the adult drug abuse unit at Södermalm during the time period 2002-2010. At the baseline the clients with substance abuse and co-occurring severe mental illness have more problems than other clients, primarily in the area of mental health. They spend more time alone and are more likely to engage in illegal activities. Interviewers assess their situation as more serious and that they need more help in all of ASI's areas of life than other clients.

Utvärdering av möjligheten att tillvarata energi ur processvatten : En undersökning gjort vid Olofsfors AB på uppdrag av UMIA AB.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Om att kreativt charma B2B

Previous research has recognized that advertising creativity can result in positive signaling effects for consumers, thus proving creativity to be a useful tool and not a wasteful effort within marketing. However, research within this matter has only lightly touched upon the outcome of signaling effects within a business-to-business context. Since other implications prevail within a B2B market - for instance the professional position in which individuals act, the existence of buying centers, and the heavy weight placed on most decisions - the conception and influence of advertising creativity may be altered. This paper aims to give an overview of whether increased advertising creativity results in positive signaling effects among individuals employed within a B2B context. Furthermore, the paper aspires to examine the potential influence of aspects prevailing within B2B markets, such as the need for contemplating the desires of numerous individuals involved, on the outcome of advertising creativity.

How strain and production system effects chicken welfare and quality in meat : a literature review

There are several reasons why organic chicken production is scarce in Sweden. Lack of slow growing (SG) strains combined with higher production costs, lower meat-yield and uncertainty of consumers? willingness to pay seems to be the main reasons. EU-legislations imply use of indigenous slow- or medium growing strains in organic production, nevertheless, fast growing (FG) broilers are often used due to their effectiveness. Increased consumption of processed food creates a market for conventionally rearing of very heavy broilers.

Kundupplevd tjänstekvalitet- en studie om poker på Internet

Syftet med uppsatsen är att definiera hur begreppet kvalitet ska tolkas för poker på Internet. Genom att ställa användarnas upplevda kvalitet gentemot branschens definition på kvalitet, ämnar vi att öka förståelsen för vad som betecknar en god kvalitet på en Internettjänst. Vi har använt oss av en kvalitativ ansats bestående av två djupintervjuer och två fokusgruppsintervjuer. Insamlingen av empirisk data och framtagningen av det teoretiska ramverket har varit en iterativ process. Inledningsvis diskuteras hur tjänster och kvalitet kan definieras utifrån några välkända kvalitetsmodeller, bland annat Grönroos (2002).

Den spruckna metallen : En psykoanalytisk läsning av Karin Boyes roman Kris

Karin Boyes Crisis (Kris) was published in 1934 as a contribution to the contemporary ideas of moral issues, challenging the dominating traditionalism within the literature critisism.With different kinds of stylistic procedures is Crises expressing a self which seeks to relieve itself from the repressing experience of Language. The text shows an attempt to create meaning beyond the conventional system of linguistic signs, beyond the tradition of literature.The focus in the essay is the self; the self is the basic structure and the theme of the text. Crisis shows it?s self-assuredness and points out a dialogue with the nietzschean philosophy. Nietzsche claims that the truth is a rhetorical creation, something which the language produces in the will of power.

Phycoremediation of pesticides using microalgae

Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity in biosorbing heavy metals.
