Sedan hydroformning började användas inom plåtformning i början av 90-talet har den dragit mer och mer uppmärksamhet till sig framför allt inom bil- och flygindustrin. Processen kan med fördel användas istället för konventionell teknik dvs mekanisk stansning eftersom den kan skapa delar med bättre egenskaper till lägre kostnad. I hydroformningsprocessen pressar en hydraulisk vätska ut ämnet mot formen samtidigt som cylindrar trycker på vid ändarna av ämnet för att tillföra material där det behövs. Förhållandet mellan vätskans tryckökning och cylindrarnas axiella kraftökning är en mycket viktig del i processen. Två versioner av finita elementprogrammet DYNA3D användes för att simulera processen: en standardversion och en version med en adaptiv tryckökningsalgoritm.

ABB I-R Waterjet Systems combines the robotics and motion expertise of ABB Flexible Automation with high-pressure intensifier/pumping technology from Ingersoll-Rand to provide and continue to develop innovative waterjet cutting systems for global markets. The purpose of this assignment is to develop a process water purifier. The purifier should be applicable as an option to ABB I-R?s production cell Cutting-Box. At first hand the process water should be purified well enough to let out in the municipal sewage system, but the ultimate solution is purifying the process water to the range that recycling is possible.

The aim with this paper is to investigate how the Social Democratic Party (SAP) deals with the question of economic migrants, or more specifically how the problem is represented by the Social Democratic Party, and how this representation has developed over time. The SAP's theory became recently contested by a competing theory that was caused by the predicted future demographic development in Sweden, combined with the EU's eastern expansion. The first factor contributed to the re-write of the theory, to a theory that saw economic migrants as a solution instead of a problem, in direct contrast to SAP's theory. The second factor was a direct threat to SAP's labour immigration policy. This leads to my second question, how did SAP respond to this pressure?The answers to these questions are achieved by using discourse analysis by applying a problem oriented theory on empirical material, constituting propositions, articles in mass media and parliamentary debates.

This study examines the connection between Sweden`s crime rate and financial aid, focusing on the effects of social spending on different types of criminal activity in the Swedish municipalities between 2000 and 2022. Using theories such as social support theory and utility maximization, the study investigates the relationship between economic assistance and crimes like theft, attempted murder, drug offenses, and assault. The results suggest a complicated relationship: financial aid is associated with a rise in drug offenses and assaults but a decrease in larceny and robberies, when controlling for all observed and unobserved time invariant factors in the municipal factors (a fixed effects panel data model). However, when we test our model for robustness, the effects disappear meaning that other factors that are time varying in the municipality are biasing our estimates. Examples for this may be factors like peer pressure, substance addiction, and socioeconomic conditions that have a considerable impact on criminal conduct, financial aid alone may not be adequate to curb crime.

The cardiovascular system is one of the three major body systems. When an animal in a critical state arrives at the animal hospital, it is important to know the normal parameters in order to assess the patient?s cardiovascular status. Triage is a process where you considerate the patient?s condition instead of check in time, or other criteria.

The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand. The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted. The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages. The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent). Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated. Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same. However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time. If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..

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.

The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

Trycksår orsakar lidande för patienter och höga kostnader för sjukvården. För att förhindra uppkomst av trycksår är det viktigt att identifiera patienter med ökad risk för trycksår samt att aktivt arbeta med preventiva omvårdnadsåtgärder. Ett strukturerat arbetssätt kan göras utifrån kvalitetsregistret Senior Alerts rekommendationer. Senior Alert är inriktat på förebyggande vård av äldre över 65 år och i registret registreras bland annat risk för trycksår, planerade åtgärder samt sjuksköterskans utvärdering av de insatta åtgärderna. Syftet med studien var att kartlägga täckningsgrad, utförda riskbedömningar och planerade åtgärder avseende risk för trycksår i kvalitetsregistret Senior Alert.

The purpose of this essay was to investigate the opinions of young people, age 14-16, at a school in a middle-sized city in Sweden, concerning narcotics. The questions we asked ourselves were;-What are young peoples' ideas of narcotics?-What do young people imagine when they think of a drug addict?-What reasons do young people give to start using narcotics?-What gender-related opinions do young people have regarding drug abuse?-What do young people think about legalization of narcotics?For this purpose we interviewed six girls and six boys. We interviewed them one at a time, for about an hour each. We used a qualitative method for the interviews.The young people in our study described narcotics as "dangerous".

Results: The analysis resulted in four main themes; difficult disunion, environmental constraints, interpersonal difficulties and communicative difficulties.

Svenska Lantchips is a Swedish SME sized snack manufacturer. Being a small, medium sized, family-owned business with branches throughout the world, they make an interesting company for a case study. The case study I have conducted focuses on the internationalisation process of this family owned company ? how they, despite their size, find ways to keep up an unique business structure, designed for internationalisation.The aim of this essay is to compare Svenska Lantchips? internationalisation process with traditional internationalisation theories and see if these are compatible with this company. The theories used are The Uppsala Model, The Network Model, and The Born Global Theory, with The Born Global Theory representing the younger generation of models.After undertaking an in-depth interview with Michael Hansen, business developer at Svenska Lantchips, I collated a substantial amount of material, which I have used as the basis of this essay.

In 1972 the regulations on tax surcharge were introduced. In the new system the sur-charge are imposed by the Tax Authority (skatteverket) and not the Court. Since 1995 the European Convention on Human Rights constitute law in Sweden, which means that Sweden is forced to guarantee its citizens the human rights in the Convention. Article 6 in the Convention states that everyone, in the determination of his civil rights and obligations or of any criminal charge against him, is entitled to a fair hea-ring within reasonable time. The Article also expresses the right for anyone charged with a criminal offence to be presumed innocent until proved guilty according to law (the presumtion of innocence).
