Today there are many applications of digital terrain models (DTM) and the requirements of low uncertainty increases. Most of the DTM are produced with Global Navigation Satellite System (GNSS), terrestrial laser scanning (TLS), airborne laser scanning (ALS) and total stations. Guidelines for the preparation and verification of DTM are found in Swedish Standards Institute ? Technical Specifications (SIS-TS) 21144:2007 and SIS-TS 21145:2007. These were defined in collaboration between Swedish National Rail Administration, Banverket, and Swedish Road Administration, Vägverket, to satisfy the needs of requirement formulations in the production of DTM planning, design and construction. The purpose of this paper is to produce and control DTM over Åkermans kulle, located west of the University of Gävle, according to SIS TS 21144:2007 using GNSS with network-RTK, TLS and ALS.

 The purpose with this thesis was to develop a designguideline which will simplify the development of new products that will be laser welded. The need for this thesis has come forward from the quality problems that Volvo Construction Equipment, Components Division is having with their laser welding manufacturing unit. The reason for the problems emerges from the bad communication between the development unit and the manufacturing unit within the company when the products produced today was developed. This resulted in products that were hard to and in some cases almost impossible to weld. To avoid these problems from occurring again it was needed to gather the experiences within this area and compile it and present in a brief a pedagogical manner. The information for the groundwork of our results has been gathered by interviews of several key persons in Volvo Construction Equipment, Components Division.

Älvkarleby, landscape character and design proposal is a Graduated Thesis (30 ECCcredtis), in the subject of landscape planning at the Swedish University of Agricultural Sciences, the Department of Rural and Urban Development. This thesis is a study and implement of the method "Landscape Character Assessment" (LCA), developed in England and Scotland as tool to analyse and highlight the landscape in different planning processes. The purpose of LCA is to increase the understanding and strengthen the role of the landscape. The thesis consists of three main parts: landscape characterization, guidelines and a design proposal. The landscape characterization emphasizes the values of the landscape in different types of planning processes, a documentation to base estimations on in any kind of change in the area. Theese estimations have resulted in guidelines that give proposals to the development of the landcape, focusing at the desingproposal.

Femsjö is a small parish situated in Hylte municipality, Växjö diocese. The parish has a total area of 8230 ha of which 5000 ha are covered with forest. There have not been any large industries in the parish offering work opportunities for the inhabitants, so they have had to generate income from their land and the forest. Instead of going to the bank to get a bank loan the people of Femsjö parish went out in to the forest and harvested trees for timber and extra cash revenue. Production of pine tar and potash were two other ways that the residents of Femsjö parish could earn extra money for the household in order to keep starvation away.

Detta examensarbete behandlar konceptframtagning av ändstationer till en föreslagen automatbana mellan Luleå Centrum och bostadsområdet Kronan. Kollektivtrafik tillhör framtiden och fungerande system är ett krav när nya städer byggs. Dagens kollektivtrafik kräver mycket stora subventioner från skattebetalarna och många system bär bara bråkdelar av sina kostnader. NoWait Transit AB har tillsammans med företaget ReRail AB ett nytt tågkoncept som anses vara billigare, miljövänligare och kräva minimalt med underhåll.Arbetet inleddes med en nulägesanalys av berörda företag och Luleå kommun vilket gav nödvändig förståelse för NoWaits tågkoncept. Deras koncept går ut på att man skapar en tågbana med kontinuerlig drift, liknande en rulltrappa.

Peat litter is a soft material with high absorbency. About hundred years ago many farmers in Sweden used peat litter to their dairy cows. After the World War II the use of peat litter decreased and the farmers used more straw. Nowadays (year 2007), when it is harder to find straw and sawdust to buy, peat litter is advancing again. The purpose with this study is to investigate peat as a litter to dairy cows.

Helsingborgs stad är en stationstät kommun. Utmed tre järnvägslinjer finns inte mindre än tio lokaltågstationer. Intentionerna i kommunens översiktsplan är att lokalisera bebyggelse i stationsnära lägen för att skapa en flerkärnig stadsstruktur och att leda in landsbygdens grönstruktur in i de centrala delarna av tätorten. Behov och önskemål om ytterliggare tre stationer finns och Raus, i södra Helsingborg, är ett av de önskade stationslägena. Fram till 1966 hade Raus en station och i samband med anläggandet av Västkustbanan skapades återigen förutsättningar för en station.

This study was conducted at VikingGenetics' bull breeding station in Falkenberg, Sweden. The bulls waiting for the results of their progeny testing at this station are either kept in group housing or individual housing. Since both of these housing systems have advantages and disadvantages, it was in the interest of VikingGenetics to know which of these housing systems is the best. The aim of this study was to investigate the welfare of the bulls in these two housing systems through behavioural observations and the use of activity monitors. In the preparations for the study 16 bulls, 8 in each housing system, were chosen.
