Att uppskatta lövyteindex med satellitdata Vegetation har unika spektrala egenskaper som kan användas inom fjärranalys för att få information om viktiga ekologiska parametrar, som t.ex löyteindex (eng. leaf area index, LAI, lövyta per markenhet). LAI styr många ekologiska processer som fotosyntes och transpiration. Med hjälp av satellitbilder kan man uppskatta LAI i stor skala. Vegetation absorLeaf area index, LAI, is an important biophysical parameter in ecological modeling. It is the ratio of leaf area per unit ground area. To obtain LAI over large areas in a fast and convenient way the use of satellite data is important. Aim of the project was to determine if there is a relationship between LAI and red-, NIR reflectance and a couple of vegetation indices: Global Environment Monitorin

We live in an age of fast changes, where updating has become a way of living; constantly forcing ourselves to change as we try to make sense of our existence. Thus there is a need for openness to the kind of learning which is incorporated with the individual’s process of change; a constant becoming through continuous forms of lifelong learning. In this qualitative study I explore and present two d

Methane emissions from Northern wetlands constitute a substantial part of the total natural emission of methane, a strong greenhouse gas. Both environmental and biotic factors influence the production, oxidation and transport of methane and hence its net flux. The methane emission from Northern wetlands is highly variable both spatially and temporally. As many factors influence the methane flux, k

Syftet med denna uppsats är ringa in den diskrepans i syn på Lundsbergs internatskola som finns bland utomstående och invigda. Arbetet är till sin form kvalitativ och i enlighet med den kvalitativa traditionen är det intervjupersonernas egna erfarenheter som lyfts fram. Parallellt med intervjuerna studeras utbildningssociologiska texter, i synnerhet Pierre Bourdieus teorier och texter kring elitsk

This design project addressed the need of a real company (which works with fishing boats) to expand its own audience towards a new market and questioned whether its actual product portfolio can fit and be successful in that new environment. The main intention with this project was to explore forms and shapes, which have been the major focus of the work, even though other several parts have been i

Detta är en kvalitativ studie som avhandlar ämnesintegration och hur det kan tillämpas av lärare i musik och engelska. Den ger även en inblick i hur lärare jobbar med det centrala innehållet i musik, med specifikt fokus på den del som kallas musikens sammanhang och funktion. Fyra lärare med ämneskombinationen musik och engelska har intervjuats. Jag har även gjort litteraturstudier för att få en dj

Studien syftar till att undersöka hur anställda som arbetar enligt konceptet hot desking uttrycker sin organisationsidentifiering (OI) samt hur styrkan av OI förändras över tid. Tre öppna frågor, med utgångspunkt i hot desking, ställdes via en internetsurvey till 100 anställda på ett teknikföretag verksamt Sverige. Mael Scale användes som ett komplement för att mäta styrkan av organisationsidentif

Uppsatsen består av en tematisk/estetisk analys av dagboksfilmen Diaries, Notes, and Sketches (Jonas Mekas, 1969). Analysen är dels förankrad i biografisk information (en traditionell auteurstudie) och i olika samhälleliga kontexter (ideologikritik).

The author examines reasons for divergence of GDP per capita among the members of ECOWAS, a RIA in West Africa of 15 members. Also, WAEMU, another RIA in West Africa, is analyzed although to a smaller extent than ECOWAS. Mainly consequences of trade diversion and agglomeration effects are considered. An analysis of the dispersion of GDP per capita between the members is carried out to find evidenc

Gehörsundervisning är ofta obligatoriskt i musikutbildningar. Trots att många moment inom gehörsundervisning, såsom prima vista-sång, kräver en mängd kognitiva färdigheter visar tidigare forskning att den kognitiva sidan av gehör sällan behandlas inom musikpedagogiken. I studien analyseras forskningsresultat från musikpedagogik och mer kognitionsinriktad forskning för att undersöka i vad mån resulEar training (E.T.) is often mandatory in music educations. Although activities in E.T., like sight-singing, requires a number of cognitive skills previous studies report that the cognitive aspect of E.T. is rarely addressed in music pedagogy. The study analyses research related to E.T. from additional scientific disciplines, that generally focusses on cognitive skills, in order to investigate to

Combining the fields of sport, gender and pedagogy within the setting of voluntary sports clubs, this thesis studies floorball as a pedagogical context within which the floorball players construct meaning of their sporting practice. Based on interviews with five Danish male floorball players and their experiences with playing floorball, this thesis analyzes how the floorball players construct the

This thesis is based on an ethnographic research on the role of health and public health care in neighborhood pubs in Helsinki. The goal was to understand why potential customers of the public health care services do not utilize the services offered. Based on the new understanding generated, a pilot health care service was developed in cooperation with two pubs, municipal health care, and the nurs

The strong CP problem and its solution are treated on the undergraduate level. We first review the theoretical background of symmetry and symmetry breaking in particle physics. The Goldstone model is treated for several simple systems: the linear sigma model, the Higgs mechanism and the interpretation of pions as pseudo-Goldstone bosons in QCD. The problem of lack of CP-violation in strong interac

In this thesis, the Arctic sea ice volume and thickness evolution over the time period 1850-2100 is analysed. The analysed data is provided by the CMIP5 climate models, which contributed their output for the IPCC Fifth Assessment. The results were compared to the reanalysis data series PIOMAS. Three RCP projections, with different greenhouse gas emission scenarios, were used for the time period 20

Disney har sedan 30-talet legat i täten för tekniska och artistiska landvinningar och har med sina filmer byggt en kanon som gjort bolaget synonymt med animerad film. Denna uppsats syfte är att undersöka de estetiska beståndsdelar Disneys filmer är uppbyggda av, där fokus ligger vid färgsättningen av de tecknade filmerna. Med hjälp av semiotisk stilanalys behandlas färganvändningarnas utseenden oc

Recent trends of permafrost thawing in the subarctic are expected to cause increased release of dissolved organic carbon (DOC) to inland waters, which might have cascading effects on downstream aquatic ecosystems and release of CO2 to the atmosphere. This study therefore aimed at evaluating the applicability of an empirical band ratio algorithm for estimating chromophoric dissolved organic matter
