Modellering och reglering av drivenheter i gaffeltruck

To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.

? Som att slicka på en regnkappa. En kvantitativ studie av kvinnor som har sex med kvinnor och sexuellt överförbara sjukdomar/säkrare sex

The background to this thesis is that we know very little about lesbian and bisexual women's sexual health in Sweden, particularly in relation to sexually transmitted infections (STI) and their transmissions. An internet-based questionnaire with self-selected participants targeted to the group WSW (Women who have Sex with Women) has been implemented. An international survey on the subject shows that the WSW has sexually transmitted infections. This is also in line with the results in this study. The most common sexually transmitted infection in the survey is chlamydia which 12.3 percent have had.

Dimensionering av bärverk av stål : En jämförelse mellan Eurokod och BKR

The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.

Systemförvaltningsmodeller ? verklighetsbeskrivning eller idealiserad bild?

This study will shed light on the subject of system management and system management models. It is important that everyone within an administrative organization understand business objectives and needs of the users who work with the systems. It is vital for the activity to form a structured approach for its management, which includes a system management model. Every company has its individual system management model that is tailored to support their management of a business IT systems. According to Brandt (2000), a system management system model is defined as "an idealized image of how you want the system management work is conducted".

Nitrogen fixation among boreal feather mosses along a clear-cut chronosequence

The Swedish boreal forests are limited by nitrogen (N) availability. While biological N2 fixation by cyanobacteria hosted by pleurocarpous feather mosses are important sources of N input to natural boreal forest ecosystems, little is known about the patterns of N2 fixation in silvicultural systems. This study investigates the biological N2 fixation rates of two boreal feather moss species (Pleurozium schreberi and Hylocomium splendens) along a chronosequence from clear-cut to mature forest, as well as the vegetation characteristics along the chronosequence. Measurements and samples were collected from 32 forest sites that were classified into four age classes (clear-cut, pre-commercially thinned, thinned and mature forest). The sites were located near the city of Arvidsjaur in northern Sweden.

Sjuksköterskans omvårdnad av patienter med krigsrelaterade amputationer : En litteraturöversikt

Background: War-related amputations are represented by a unique group of patients because of the wounds complexity and scope of several serious injuries. To prevent and avoid care suffering and suffering of the patient, this study focused on the nurse's way to manage and identify the needs of this unique group of patients who have suffered from war-related limb loss. To undergo a traumatic amputation is a big change for the victim, and the nurse has an important role in responding to the patient and their needs Aim: To illuminate nursing care of patients with war-related limb loss. Method: The chosen method was a literature review. The data consisted of nine qualitative and three quantitative studies.

Vindkraft eller kärnkraft - En jämförelse

The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).

Fick algblomningen i Östersjön 2005 några ekonomiska effekter? : Fallet turistnäringen på Gotland

Algal bloom is a naturally occurring phenomenon and occurs in all waters around the world but in recent years, algal bloom in the Baltic Sea has become more massive and more widely spread. When an algal bloom negative effects on the seawater quality, it may have an impact on tourism in the Baltic Sea. The aim of this thesis is to study, through a survey based on a production function approach, whether an environmental change as algal blooms, influenced the Gotland tourist accommodation industry and their "production of attractive overnight? in the summer of 2005. The results show that algal blooms did not have a great impact on companies ?production of attractive accommodations".

Budgivningsprocessen vid ett fastighetsköp : lockpriser kontra accepterat pris

Detta är en undersökning som är gjord för att jämföra prissättningen av fastigheter som är till salu i Sverige och Spanien. För att avgränsa oss har vi valt att jämföra Stockholms innerstads prissättning med prissättningen i Palma på Mallorca i Spanien. Lockpris fenomenet har fått hård kritik under den senaste tiden i media. På grund av denna kritik så har många mäklare, speciellt i Stockholms innerstad, gått ihop och arbetar mot att undvika lockpriser och har infört begreppet accepterat pris. Dock kan accepterat pris uppfattas som ett nytt ersättningsnamn på lockpriser.

Finns det något positivt med positiv särbehandling? : A case study of the progress of equality of the sexes in the Swedish armed forces

The aim and purpose of this paper is to identify and investigate the effects of affirmative action as a tool to improve the equality of the sexes in a male dominated organisation such as the Swedish armed forces. The study takes a qualitative approach, using feminist theory as a point of departure. Primarily socially based differences between men and women are identified and the resistance towards change is taken into account.To understand the impact of affirmative action I have observed the political debate on the subject and contrasted it to the ongoing debate from within the armed forces. Extensive interviews have been held with both men and women from varying ranks and ages to understand what the overall opinion of the method is.My results show that there is a widespread animosity towards affirmative action as a method of improving equality. Both in the political debate and within the organisation in question.

Kateterrelaterade urinvägsinfektioner ? brist på effektiva preventioner ? En litteratursammanställning

Background: Urinary tract infections caused by indwelling urinary catheters causes unneccesay suffering among those it affects. These infections are also financially straining on the health care services. It is therefore of importance to gain knowledge about which evidence based preventive interventions that have the possibility to reduce the risk for bacteriuria and urinary tract infections among patients with indwelling urinary catheters. Aim: This study aimed to compile available knowledge concerning i) if silver alloy catheters does reduce bacteriuria in this patient group, ii) if aseptic catheterization does reduce bacteriuria in this patientgroup, iii) which routines for changing the urinary drainage bag reduces the risk of bacteriuria, iv) which routine genital hygenic care reduces the risk of bacteriuria? Method: Litterature was searched for in the data bases Cinahl, Medline and The Cochrane Library using the data bases? thesaurius combined with OR/AND.

Störs laxens lekvandring i en kraftverkspåverkad älvsträcka? :

The upstream spawning migration of Atlantic salmon (Salmo salar) at the confluence area between the power-station outlet and the bypass-channel in river Umeälven (flow 430 m3s-1) was compared in 2004 and 2005, two years with different experimental flow-regimes. In 2004 the water flow in the bypass-channel was altered during the day with increased flows during the nights while the water flow in 2005 mainly was altered between the weekdays and weekends. Salmon showed altered migratory behaviour in this confluence area, assessed with telemetry (n=116) and echo-sounding, with up- or downstream responses depending on flow-changes in both the bypass and the power station outlet. Increased turbine flow through the power-station generally attracted salmon into the tunnel outlet area while increased spill-flows facilitated salmon to enter the bypass. Echo-sounding in the confluence area showed an increased swimming activity up- and downstream due to time in the day and flow-rates through the tunnel outlet. No changes in activity could be detected due to increasing or decreasing flow through the hydro-power facility.

Att skapa ett enhetligt användargränssnitt : Användargränssnitt baserat på personametoden som koncept istället för empiri

Man's life has changed in many ways since technology made it?s entry for public at large. In response to this change the science of human-machine interaction was invented. It has in turn evolved into human-computer interaction. With this science the focus is on the customization of the system for the actual person who will use it.The thesis has been implemented in a telecom company's development department.

Raskolnikov i klassrummet : Brott och straff som utgångspunkt för värdegrundsdiskussion i svenskämnet

Syftet med uppsatsen är att hitta motiv i Brott och straff och se hur värdegrunden gestaltas i dessa. Samt diskutera hur skönlitteratur kan användas då man diskuterar värdegrund i skolan. Vår frågeställning är: Vilka motiv finns i Brott och straff och hur gestaltas värdegrunden i dessa motiv?I analysen utgår vi ifrån reader-response teorin där texten påverkas av läsarens erfarenheter och sammanhanget som texten läses i. I vår analys presenterar vi de motiv vi har analyserat fram i romanen, motiven analyseras fram med hjälp av en indirekt karaktärisering.
