Hinderdetektering och kartläggning för autonom robot
In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.
Betesskador på lärkplantor
The purpose of this study was to show how the Hybrid Larch (Larix eurolepis x) are used by large herbivores in terms of grazing and fraying. More specifically I studied how impact on the seedlings was affected by forest stand area, tree height and stem density (stems/ha).The survey was done in Jönköpings county in southern Sweden.
About 50 % of all stems that are measured are damaged by grazing and 5,8 % was damaged from fraying. The conclusion of the study is that the biggest influencing factor is the height of the seedlings. The size of the stands and number off seedlings per hectare have almost no impact on the injuries on the seedlings. Fraying are common on trees smaller than 3 meters, and doesn?t occur on trees above that height.
Tillsats av biokol till en svensk sandjord : effekter på lustgasavgång, kväveretention och andel vattenfyllda porer
In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable ammoniumwas negatively correlated, with the specific area of the biochars. The question was raised whether thenegative correlation between extractable ammonium and biochar specific area reflects the amount ofammonium present in the soil or its extractability from the biochar, and whether methods forextracting soil mineral nitrogen, like KCl-extractions, have to be modified for application on biocharamended soils. There was a tendency of increased nitrate retention and KCl-extractable nitrate withbiochar and KCl-extractable nitrate was positively correlated with the specific area of the biochar. pHwas higher for all biochars compared with control, although the differences were not significant, andWFPS was lowered by biochar addition, significantly in one case.

Konstmuseum i Uppsala
Ett konstmuseum på 3000 m² i Uppsala vid Fyrisån. En utmejsling i det kulturella och historiska stadslandskapet i Uppsala där besökaren kan vandra längs museumet alla tider på dygnet. Genom att ge små glimtar lockas besökaren att besöka de samlingar av modern och klassisk konst samt den samling av grafiska tryck som finns på utställning. Formen tillåter rörelse i alla riktningar och förlänger kajen. Byggnaden är utformad i trä som är konturskuren på ytterskiktet med en stomme av ett rymdfackverk i stål.
Elevers uppfattningar av operationer med negativa tal
Negativa tal har inte alltid varit lika självklara som de är idag. En elev som aldrig tidigare mött ne-gativa tal, än mindre räknat med dem, kommer troligtvis anse att det är ologiskt att tala om äpplen. Forskning visar på att det finns en mängd svårigheter och missuppfattningar om operatio-ner med negativa tal. En del av dessa missuppfattningar grundas i den tvetydighet som finns be-träffande minustecknets funktioner - då minustecknet både används som operator och som be-teckning för negativitet. Den negativa talmängden är en del av kursplanen i matematik för årskurs 4 till 6.
Interest rate and exchange rate impact on U.K. firms
The purpose of this paper is to apply the Dual-Effect hypothesis in Pritmani, Shome and Singal paper (2003), in order to analyze the exchange rate exposure on firms listed on the U.K. market. The study will examine if the foreign involvement of the firm will affect the share price of the firm.In addition to evaluating the Dual-Effect hypothesis in Pritmani et. al. (2003), we will evaluate the effect of foreign interest rates impact on U.K.

Reglering av naturgasdistributörer : En undersökning av benchmarking på marknaden för naturgasdistribution
This paper discusses the advantages and disadvantages of using different benchmarking models to measure and compare the efficiency of Swedish gas distributors. It also discusses to which extent the results of a benchmarking study should influence the revenue-cap which will be implemented in the gas distribution sector in Sweden from year 2011. The discussion is based on arguments from both theory and practical applications of benchmarking. The results suggest that benchmarking Swedish gas distributors against distributors in another country using a parametric model is most favorable, but the reliability will be increased if non-parametric models are used also. Partial and total productivity measures could be used to confirm results of other benchmarking analyses.

Kunskapsbakgrund och teoretiskt perspektiv
Enligt Vygotskij så lär sig barn/elever och utvecklas när de får samtala och göra relevanta aktiviteter tillsammans med andra. Det finns många olika anledningar till att elever har räknesvårigheter såsom t.ex. bristfällig undervisning eller stimulans eller inte haft en fullständig skolgång, men det kan även bero på oförmåga att hantera tal och kvantiteter. Eleven som får ge uttryck för sina egna tankar, lyssna på andras tankar och komma på nya lösningsförslag genom samtalen i små¬grupper eller helklass kan leda till att eleven finner andra lösningsförslag, som kanske är bättre än sitt eget.
Integrerade folk- och skolbibliotek. En studie av två tänkbara organisationer.
The aim of this master's degree dissertation is to compile examples of different ways of planning, implementing and following up the organisation of two integrated libraries, which serve both the general public and the school. In order to respond to this, we formulated the all-embracing question: How best can the integration of libraries for schools and the general public be planned, implemented and followed up? This formulation gave rise to four further questions. In order to answer these questions, the problem formulated and our basic aim, we have studied the relevant literature on school libraries, libraries for the general public, and integrated libraries. These sources comprise official reports on this theme, dissertations, and more topical articles.
