Breakdowns of welded structures are usually a consequence of fatigue loading. Fatigue fractures are commonly initiated in the region close to the weld toe but can also initiate from the weld root and from discontinuities inside the weld. The purpose of this investigation was to examine the weld quality of welded joints produced at Volvo Wheel Loaders factory in Arvika. The goal of the investigation is to give a clearer insight regarding factors influencing the fatigue strength of the welded joints and thereby give a better foundation for fatigue strength calculations.The investigation is including examination of the weld geometry, weld discontinuities and the effects of shot peening. Mainly three different methods for collecting test data have been used: Plastic replicas cast on the weld profile, weld specimens from a rear frame belonging to a wheel loader of model L110E/120E and Almen testing of the shot peening.The results showed that it is not possible to control even transition between the weld material and the base material without after treatment.

A change towards using more biofuels than fossil fuels is taking place in Sweden, and in many other parts of the world. This makes the use of fuel pellets increasingly popular, causing a greater demand for sawmill sawdust products. There is a trend towards the use of multiple types of shredders, instead of a single type in each sawmill. The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning.

Today multi-touch technology is the basis for many new techniques designed to improve interactions with computers and mobile devices. It seems that multi-touch screen interface makes the user handling very natural in the sense that there is no need for a manual in how to interact with the object on the screen. The aim with this paper is to establish a fundamental set of design principles intended specifically for large multi-touch interfaces. To reach this goal we have implemented a couple of sub-goals beforehand: It was essential that we acquired a good understanding of the current state of the multi-touch interface and the different implementations that exist today. To make this possible we constructed a multi-touch display, "Rosie". Knowing how the hardware is produced today will help us understand the limitations and also the possibilities of the design implementations today and in the future. We also needed to devise a sound interaction design process that conveys the modern designers work.

The purpose of this text is to show how social class is (re)produced and created in the short stories?Draksådd? byMaria Sandel and Ivar Lo Johanssons ?Nya tänder? from Statarna I and to point out ways that the short storiesmay be useful from an Educational Perspective. Maria Sandel was the first (recognized) female author to writein the genre of Working-Class Literature in Sweden and Ivar Lo-Johansson is a recognized authorship who ismost famous for his novels portraying Statarna. The analysis focuses on how the teeth motif is portrayed in theshort stories. My analysis proves how the teeth motif is important in portraying the construction of class.

The aim of this paper is to critically examine and analyze how the informal performance about masculinities and femininity are being expressed and produced by the text and pictures in Huddinge kommuns internal magazine for the staff working within the public administration. The concrete questions are:By which patterns constructs the performance of gender in Huddinge kommuns internal magazine for the staff working within the public administration?Are the femininity and masculinities being expressed in a static way or have it changed in Huddinge kommuns internal magazine for the staff working within the public administration throw the examined years 1985, 1995 and 2006?A quantitative and qualitative method is used. The point of departure is organization theory in a gender perspective. With the gender organization theory we examine the structures, leadership, symbolics and changes through the examined years.

Milk yield levels in dairy cows are influenced by many factors such as nutrition, breed, health status, management and environment. This study was conducted among small scale farmers in Zambia, where the climate can be dry for up to six months per year and cause a lack of green pasture for livestock and on-farm produced feed. The purpose of this study was to identify management factors that can influence milk yield at small scale dairy farms in Zambia, and present advice that could improve productivity, without the need of expensive investments. The study included semi-structured questionnaires presented to the farmers (n=29) including questions about cattle management and milk production. Testing of somatic cell count (SCC) with DCC (DeLaval Cell Counter) from herd milk samples (n=56) and observation of housing and animal body condition on-farm was also made.

The society has strongly developed and changed the condition of the trades. The retail trade is no exception; it has changed and developed in the same pace as society. The retail trade is a very broad and extensive trade as all people come in contact with frequently. In the past people shopped locally but nowadays people have the entire world as their marketplace because of the development of Internet. Globalisation gives customers wider opportunities, which demands new and different sales concepts.

The purpose of this essay is to examine at how to portray characters in the stories and narratives which depicts one of these children's books and if they really have something to ethnicity and its identification to be done.The Research questions is: What are the different identification markers given, to the reading child in the books, which might indicate that the story depicts people of different ethnicities? How are the characters portrayed in the story and which role is assigned to the main character? What story is portrayed and is it relevant to an identifier can occur?The conclusions of the five children's books shows that it is important with identifications markers, to show that there are different ethnicities. For example the analysis revealed the specific features of the illustrations and how the books portrayes someone with a different ethnicity and cultural background as something exotic.In the texts, the analysis showed how it occurred ethnic differences, by explicitly demonstrating differences between the characters. It was found that the characters were produced mostly as good, happy, curious, suspicious and unsympathetic. Common to all the main characters was that they had been placed, in one for them unusual context and that they were trying to assimilate to the new situations.Depictions consisted of realism and fiction.

Den allvarsamma leken (1912) by Hjalmar Söderberg has been regarded as one of the greatest love novels of Swedish literature. The story about Arvid Stjärnblom and Lydia Stille and their extramarital love is marked by timeless universality.In this essay, I will examine this notion of love as a prediscursive value, by means pro¬vided by foremost poststructuralist theory. With Derrida?s conception of deconstruction, the analysis will reveal the constructedness of the true love in Söderbergs novel. Examinating typi¬cal logocentric binarisms the essay will show that the notion of true love is constituting a term in an oppositional relation with, in this specific case, the marriage sanctioned by society.

I det här arbetet undersöker vi hur retrotrenden påverkat digitala spel. Vi undersöker hur retro blivit en erkänd stil och varför den har blivit det. Vi undersöker dess koppling med nostalgi, hur nostalgi fungerar och varför man kan tänkas vilja använda sig av det när man ska utveckla ett digitalt spel. Retro är inte ett fenomen som är medie exklusivt till digitala spel, vi undersöker hur retro verkar i andra medier och hur medierna blandar retroelement med varandra. Det är inte ovanligt att samtida digitala spel influeras av retrospel eller rent av utvecklas i syfte att bli ett nyproducerat retrospel, detta är något som vi gestaltar i vår produktion av ett digitalt spel.

Wallyfy is planned to be a social webmagazine with a focus on good content, with a quality check and moderation of the published content. The author of the study provides Wallyfy with thoughts and ideas about the website content and functionality. The main problem of the study was to explore what makes good content in social media for the potential users of Wallyfy, also using this insight to provide Wallyfy with directions for making decisions regarding both functionality and content. The theory of the study is being used as a starting point for understanding the phenomenom social media and to easier grasp the problem. The method of the study is based on user- centered thinking in design, where the author seeks to understand the participant?s emotions, values and dreams.

This thesis is intended to respond to the extent to which South African textbooks on the subject of history is linked to the governmental policy documents and whether they are producing and reproducing national identity. The two textbooks are aimed at students in grade 10. Both books were produced in 2008 but published by different publishers.The essay is based on Norman Faircloughs critical discourse theory which has been supplemented by Michael Billings theory Banal Nationalism, which assumes that it is the national words that remind us daily of our homeland that is producing and reproducing national identity.  The survey shows that both textbooks are closely tied to the government policy document for the teaching of history. The textbooks refer to the policy, both explicitly and implicitly. The two textbooks reproduce a common national identity in South Africa based on the discussions taking place in society.

This report shows the process of the development of a sensor module for the seed drills of Väderstad Verken AB. The module is supposed to replace existing solutions, provided that it is better from both a constructional- and an economical aspect. The purpose of the sensor is to continuously give the driver information about the level of height of the front- and drilling tools and the main purpose of the sensor is to allow the seeds to be placed at the desired depth. The sensors which have been taken into consideration have all been of an analogue type and have a protection class of minimum IP67.The methods applied have been taken from the book ?The Mechanical Design Process? by David G.

The first aim of this study is to describe how the public employment service (PES) producesoccupational descriptions. The second aim is to analyse the conditions for that production.Method: The empiric material consists of seven qualitative interviews with employed at PES,operational plan for the team working with descriptions on occupations and observation notes.The overall theme in the study is Foucaults perspective on power. The conditions forproduction of occupational descriptions are understood in the light of the governmentality perspectiveand the concept of employability. Bourdieu´s concept habitus, symbolic violence and capital are usedto articulate the officials? values and experiences.Eight officials at PES produce the occupational descriptions.

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.
