Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

A growing number of cities and municipalities in Sweden begin to work with city models in 3D. For the most part the models are used for visualizations of ongoing planning processes, but also for the analysis of noise, shadow studies and environmental disaster simulations.Gothenburg continues to develop the use of 3D maps in municipal operations and is demanding a way to create building elements (walls), which generates in 3D buildings, from roof constructions that are mapped from the primary map. A method has been investigated in the present study. The results are then presented as a 3D model of buildings, along with a terrain map that will facilitate the localization of the area. The created 3D buildings are then compared with roof-data from the primary map to see how well they harmonize with each other.

The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.

Barn ska få möjligheten att växa upp med, och uppleva, vuxna sammanhang samt visuell komplexitet i sin omgivning. Utan dessa utbyten och objekt i sin omgivning utvecklas barns delaktighet i samhället som ansvarsfulla medborgare långsammare. Detta är projektets utgångspunkt. Förskolan Bullerbyn är, precis som namnet tyder på, en liten by med olika verksamheter där förskolan ligger i fokus med en central gård. Barnen kommer i kontakt med vuxna som arbetar i byggnaderna intill: bageriet levererar bröd och fika, restaurangen lagar mat till lunchen, ett snickeri delas med ateljéerna, utställningslokalen drar till sig både vuxna och barn i sin verksamhet och kontorsfolket kommer och går genom uteplatsen.

This study is a thorough comparison between what people think about the website www.sl.se, which is a Swedish web-based travel planner for Stockholm metropolitan public transport (such as subways, busses and suburban trains), and how these views compares to the design of the actual website itself. The travel planner offers a wide range of functions and services for their targeted audience to find the fastest route between their current location and their destination. These functions are for example real time information on hold ups and malfunctions on different travel routes, and an interactive map of specific destinations so that the user can get a clear view of the area and nearby traffic stops. But how much does the average user care for these functions, and how often are they used on an average visit? What are the users? motivations when they visit the site? Earlier research suggested that there are services and functions on this website that are useful and well crafted, but that some people may not be aware of.

Arbetsförmedlingen is the Swedish national authority responsible for the work politics, and its main purpose is to create and build a solid and sustainable job market.Economic crises together with changes in the society and in the organization over the past few years mean that the unemployed individuals that come in contact with Arbetsförmedlingen are no longer a homogenous group. A lot of effort is put into helping those who may find it difficult to enter the work environment, such as youths (19 ? 26 years old), people who have been unemployed or on sick leave for a long period of time, people with disabilities or immigrants who are newly arrived in Sweden.A harder social and economic climate can lead to frustration among the unemployed which mean that security measures at the offices has had to become adjusted. Local offices now have a public area where they have meetings with their clients and a locked open plan office space to which the public have no access. Working within an open plan office environment can cause health problems, mostly due to the constant background noise that comes from people having conversations on the phone, or with each other.

In today?s society we depend on technology to perform the simplest tasks. Whether we are engaging in conversation with a friend or are navigating in traffic, we are likely to be found with some technological device in our hands. This dependence has grown over a period of time, and many of us have failed to reflect on the impact technology has had on our lives. The emergence of so-called One-to-One projects, where teachers and students gain access to a personal laptop, does however provide an excellent opportunity to do so.

This paper constitutes graduate work at the Depart-ment of Urban and Rural Development at the Swedish University of Agricultural Sciences. In this paper the urban structure of the million program suburb Husby in Stockholm is examined and what effect this structure has on social life in the area. The main objective of the study has been to, with the help of morphological analyses, examine how to create meeting places and make the Husby Park more accessiblefor the inhabitants in Husby. There has been a selection of analyses to ensure that Husby?s spatial relationship with surrounding suburbs as well as local spaces in the Husby Park is described.

The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.

Syfte: Att undersöka om det finns belägg för att contrarian strategier genererar högre avkastning än Stockholmsbörsens marknadsindex och om detta i så fall beror på en småbolagseffekt. Metod: I vår event studie valde vi att undersöka stockholmsbörsen under åren 1993 till 2005. Under perioden skapade vi 8 portföljer med 20 aktier i varje, för dessa bolag satte vi ett gränsvärde på 150 Mkr. Vi utförde även ett liknande försök men då med en gräns på 1 miljard och satte antal aktier i portföljen till 10. Detta för att testa förekomsten av en småbolagseffekt på våra resultat.

Buller är ett stort arbetsmiljöproblem, som kan leda till ohälsa. Det är viktigt att personal som i sitt arbete löper risk för hörselskador använder hörselskydd. Studiens syfte var att beskriva och jämföra användning av hörselskydd bland personal som arbetar i bullrig arbetsmiljö inom verkstadsindustrin. Studien var en tvärsnittsstudie med en deskriptiv och komparativ design. Data samlades in med hjälp av en enkät.

By doing this thesis I want to open up farmers and tractor drivers mind to see that there is several risks with their work. There is a number of risks that everybody probably already know about, and hopefully I will, with this work, help them to see a lot more risks, to make them be more careful in the future. I?ve interviewed seventeen farmers in middle and south of Sweden. I?ve also asked them for their opinion and what kind of changes they looking forward to.

Många av Sveriges kommuner vill förtäta sina städer med bostäder och lokaler för att bygga ett mer hållbart samhälle. Ambitionenär att kunna fylla de luckor som finns i stadsbilden och använda stadsmark som tidigare inte är bebyggd för bostadsbyggnation. Examensarbetet behandlar de problem som trafikbullret genererar och som måste hanteras vid projektering av nybyggnation, samt undersöker de krav och regler som styr den tekniska utformningen och planlösningen av bostäder med hänsyn till trafikbuller. När Skanska tidigare har projekterat bostäder i stadskärnan har man upplevt problem med att få bygglov när den föreslagna planlösningen har sovrum mot bullrig sida. Fokus ligger på de krav och råd som styr placering av sovrum och försöker hitta lösningar som gör det möjligt att få bygglov med placering av sovrum mot bullrig sida.

The purpose of this study is to describe the three most significant pedagogical ideas and their impact on the national curriculum from the concept of communication. As the school is a social learning community this study looks at some teachers? perceptions and experiences of teaching with a communicative approach, and the obstacles they claim to meet. The educationist Kieran Egan argue that these three pedagogical ideas are incompatible and that a curriculum that compromises them is doomed to fail. He mean that a new coherent view on education is required and should be based on students? understandings.

Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations we­­­re performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.
