Utvärdering av metoder för framställning och kontroll av digitala terrängmodeller
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.
Värdet av FaR - Fysisk aktivitet på recept i kampen mot livsstilsrelaterade sjukdomar
Livsstilsrelaterade sjukdomar är ett växande globalt problem, och fysisk inaktivitet är en av de största riskfaktorerna. En av sjuksköterskans uppgifter är att motivera till hälsosammare levnadsvanor. En hälsofrämjande metod är fysisk aktivitet på recept, FaR®, som används i flera länder, men vars effekt även har ifrågasatts. Syftet med studien var att undersöka värdet av FaR® och vilka faktorer som påverkar det värdet. En granskning av 12 vetenskapliga artiklar genomfördes.
Skolskogen som ekosystemtjänst : En fallstudie om det sociala värdet hos skolskogen
The concept of school forest was drafted in 1970 by the Forest in School organization and is defined as an area occupied by a school for outdoor educational activity. The main purpose of this study was to examine how schools use the school forest in practice, how it can be linked to the forest as an ecosystem service and find out how the forest is taken into consideration in the spatial planning. The study is mainly qualitative in nature and has been based on interviews conducted with educators engaged in outdoor education at four selected schools in a municipality in Sweden. Focus has been on the cultural ecosystem services for school forest, for example the physical characteristics that are considered as positive, forest influence on students' physical / mental health and the educational benefits available to be in the woods. Search has also been made to see how the forest is taken into consideration in the spatial planning and also what a contract agreements involves.

Samlande vs. tillgängliggörande : En jämförelse mellan två förvärvsmodeller på akademiska bibliotek
The aim of this Master's thesis is to examine what effect two different models of acquisition have on user satisfaction with information resources at academic libraries. The two models examined are the traditional model where a subject specialist librarian makes the selection, and the user-governed model where the larger part of the selection is based on user requests. The scope is the libraries of Roskilde University, which employs the traditional acquisition model and Malmö University, which employs the user-governed. Both libraries have a user-oriented approach to acquisition. The study encompasses a close examination of the acquisition policy through document analysis and interviews with the librarians in charge of acquisitions at each university, as well as a user-satisfaction survey among the professors and senior teachers on two faculties at each university respectively.

Price adjustment and vacancies on theStockholm market ? Estimation of rent levelsdue to office-allocations
The Stockholm office market segment have for a long time been considered a safe havenwhen it comes to withstand negative turmoil in the form of rental compression due toeconomic fluctuation, especially in the CBD demographic. Recently however, a large numberof banks and institutions, amounting to some 200000 square meters, have decided to relocateto more peripheral locations with the aim of cost reductions on rent. This mass exodus isstudied with focus on rental dynamics as the result of increased vacancies. Other variables arestock changes and employment. The method is econometric combined with an interviewseries.
Demokratiteoretisk analys av läromedel i Samhällskunskap : En kvalitativ studie om det demokratiteoretiska innehållet i läromedel för Samhällskunskap 1a1 och 1b under GY-2011
This qualitative study is done with the purpose of creating understanding for the theoretical democratic content in educational materials for Civic Education courses 1a1 and 1b during GY-11, so teachers create an intentional approach when using educational materials in their democratic education. This was motivated as important considering the reduction in obligatory Civic Education for the vocational programs. The study was conducted using a hermeneutic qualitative reading method where the educational materials, more specifically two series with one book for each course, was read with purpose of creating understanding for the democratic content according to ideal democratic models: deliberative democracy, participatory democracy and electoral democracy. A text voice analysis was also conducted using Bakhtins theory of dialogic and monologue text that contributed to the general result concerning the democratic content. The results show that the electoral democracy ideal is dominant in all educational materials, there is hence no striking difference between the democratic content in 1a1 and 1b educational materials.

Konceptstudie av drivmodul till bandskotare med hybriddrift
BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.
Relationen mellan ledare och medarbetare i en decentraliserad organisation. : Hur tar den sig uttryck i en LSS-enhet
We have completed our investigation on a LSS organization located in Västra Götalandsregionen. This organization has four leaders who has responsibility for multiple devices but do not have any physical contact daily. We have seen that organizations constantly living in some kind of change, which means that organizations are becoming more decentralized. This decentralization affects leaders' way of working in the organization, because the employees are geographically dispersed in the municipality. Our survey shows that the physical meetings between managers and employees are an important factor in creating a motivated team.
Högskolebibliotekariens pedagogiska roll
The Swedish academic libraries have gone trough radical changes during the last decades. The development of information technology, the educational expansion and new pedagogical ways of learning within the higher educational system have changed the conditions, not only for the academic libraries, but also in many ways for the librarians. The aim of this Masters thesis is to examine how Swedish librarians experience their pedagogic role and task in the context of an academic library. The following four questions in this investigation were asked: How do the librarians experience the formal task that they have? How do the librarians experience the physical library environment? How do the librarians experience the co-operation with others involved in their work? How do the librarians experience their own pedagogic knowledge and competence in their daily practice? The study showed that these librarians believed the physical environment to be very important and is seen as a pedagogical tool in their daily work.
