Klassning av fjällbjörkskog enligt FAO:s definition av skogsmark med hjälp av flygburen laserskanning
Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.
Bootstrap som hjälpmedel att öka noggrannheten och bedöma precisionen vid probitregression, med tillämpning på hörselmätningar
In many biomedical contexts, e. g. when evaluating hearing disorders, the data obtained can be described as pairs (x1, y1), ?, (xn, yn) where x is a quantitative variable and y a 0/1 variable whose probability of taking the value 1 is a monotonic function of x. One way of analysing such data is to perform probit regression; thereby two parameters, b0 (= the constant) and b1 (= the slope) are estimated; the interest centres around m = -b0/b1, i.
Flotation therapy for downer cows : a retrospective study of cases treated with flotation therapy at the Large animal clinic at the Faculté de Médecine Vétérinaire at Université de Montréal
There are about 700 000 dogs in Sweden. Roughly 70 % of the dogs are purebred and registered in the database at the Swedish Kennel Club (SKC). The database includes records of birth date, pedigree, offspring and results from e.g. veterinary examinations related to genetic health programs.Every year approximately 10% of the dogs die; most are euthanized by a veterinarian. Dog mortality data is stored as digital medical records at animal clinics and in insurance databases.Dog owners tend to register their puppy in the SKC, but they rarely report that the dog has passed away.
Kvalitet på vägdata : inventering av skogsbilvägars standard samt jämförelser med lokal bedömning och SNVDB.
During 2006 SNVDB (the national road data base for forestry) is being introduced to Holmen Skog. This data base contains all information about Holmen Skogs road systems. The information will then be used in different kinds of optimisation models which only produce correct and reliable results if the input data are of the adequate quality.
Today there are reasons to believe that road data is of various qualities. The forest roads are often in a bad condition and have to be improved before a planned harvest. The cost of maintenance and construction of new roads is a large part of the total harvesting cost.
Användning av LiDAR och ArcGIS inom skogsbruk i Sverige
Light Detection And Ranging (LiDAR) har under det senaste decenniet utvecklats mycket och används som datainsamlingsmetod vid inventering av skog. Lantmäteriet genomför mellan åren 2009 och 2015 en riksomfattande flygburen laserskanning över hela Sverige och den laserskanningen ska leda till en ny nationell höjdmodell (NNH). Data som genereras från denna höjdmodell kan nyttjas av skogsindustrin för att göra skogliga inventeringar. Programvaruutvecklaren Esri Inc. har utvecklat ett stöd för hantering av denna typ av data i deras nya version av ArcGIS, ArcGIS 10.1.
Visualisering av informationskvalitet : Utformning av kvalitetsindikatorer för Lantmäteriets Fastighetsregister
Fastighetsregistret (The Cadastre) is a large and important information sourcesupplied by Lantmäteriet (the Swedish mapping, cadastral and land registrationauthority). Fastighetsregistret provides geographical information about the 3.2 millionestates in use in Sweden. Fastighetsregistret has a large number of users who trustthat the provided data is reliable, but experience shows that the data can have varyingquality. As a user it is not always possible to access more detailed information inorder to assess to what extent the data in Fastighetsregistret is reliable.The purpose of this master's thesis is to investigate the possibilities of a system with agraphical user interface that present, classify and visualize the quality of the data inFastighetsregistret. The defined user group for this suggestion is internal users atLantmäteriet who have a good understanding of Fastighetsregistret.
Högutbildad och anställningsbar? - en studie av klassbakgrundens betydelse på den svenska arbetsmarknaden
Since the 1950s new laws on higher education have led to a ?mass education phenomenon? in Sweden. This has led to a surplus of people with a university degree measured against available positions on the labor market. As a result of that development it must be assumed that in this over qualified society it is not anymore the degree but additional factors which are decisive for getting a job. In this respect the importance of the class background for getting a jobb that is equal to once level of education shall beexamined.The research was carried out by means of a Quantitative Analysis based on data from anational database called Undersökningar av Levnadsförhållanden (Survey of LivingConditions).
Informationslager för stora mängder SNMP-data
TeliaSoneras driftcentral har ett stort behov av att snabbt samla in statistisk data från noder och kundanslutningar. Insamlat data används sedan för att felsöka och åtgärda olika problem i nätet. För att säkerställa den driftsäkerhet och kvalitet som efterfrågas så behöver ett av systemen vidareutvecklas. Applikationen som utvecklats ska förbättra insamlingen och lagringen av det statistiska datat för att snabba upp analyserna av kvalitet i xDSL-nätet. Kraven på applikationen är att insamlingen, konverteringen samt lagring ska vara horisontellt skalbara.
?One Direction is not a phase like any other fandom I've been in, they're like my life? : en analys av fandom som källa till helighet
The aim of this paper is to study whether the way directioners (One Direction fans) on Twitter express self-understandings denote fandom as a sacred experience. For this purpose, the data was analyzed in relation to Nicholas Jay Demerath III typology of the varieties of the sacred experience. The method used was discursive psychology. The data was analyzed by how the fans draw the line between ?us? and ?them?, when expressing their self-understandings and their position in relation to others. Five themes were identified: (1) positioning and demarcation for membership, (2) group identity, (3) conflict, (4) the norms for behavior, opinions and language and (5) the group?s role and function.
Implementation av FlexRay prototypstack
FlexRay is a new communication protocol which is fast, reliable and flexible and therefore can meet the increasing demands on data communication in the vehicle industry. The protocol is developed by an industrial consortium containing among others BMW, Daimler Chrysler, Motorola and Phillips. Today (May 2009) Hägglunds is using CAN for data transmission in their systems. CAN is getting obsolete and has difficulties in coping with the increasing flow of communication. In this report FlexRay and its communication capacity is studied.
Utvärdering av upphandlade äldreboenden
The aim of this study was to understand how evaluations are implemented and used in procured nursing homes for elderly. Our methodological approach consisted of a single-case study research. The case in this study was Växjö municipality. Three procured nursing homes for elderly were chosen in the municipality as examples of implementation and use of evaluation. The method for retrieving empirical data and the analyzing of it was based on triangulation.
Statens järnvägar - en fallstudie om värdering av fordon i statlig ägo
Purpose: The aim of the thesis is to identify principles of valuation and to reach a solution for how Statens järnvägar can present their leased railroad vehicles in the future.Methodology: The authors have done a case study through a qualitative approach. Interviews have been done with Statens järnvägar, Näringsdepartementet and Riksrevisionen. Annual reports from Banverket and Luftfartsverket have been studied.Theoretical perspectives: The regulations that rule the authorities are a base for the study.Earlier researches done within the subject are presented in this section.Empirical foundation: The empirical foundation of this study consists of primary- and secondary data. The primary data is collected from the interviews that have been done, whilst the secondary data is composed of annual reports, regulations and various other documents.Conclusions: The authors have come to the conclusion that the method of valuation that Statens järnvägar choose, depends a lot on the vehicles hypothetical future. It is difficult to say that only one of the methods would be the correct one..
