  1. 36. Automatic Pose and Position Estimation by Using Spiral Codes

    Master-uppsats, Högskolan i Halmstad/Halmstad Embedded and Intelligent Systems Research (EIS)

    Författare :Aras Albayrak; [2014]
    Nyckelord :Position Estimation; Pose Estimation; Automatic Pose; Spiral Code; Log-spiral detection;

    Sammanfattning : This master thesis is about providing the implementation of synthesis, detection of spiral symbols and estimating the pan/tilt angle and position by using camera calibration. The focus is however on the latter, the estimation of parameters of localization. Spiral symbols are used to be able to give an object an identity as well as to locate it. LÄS MER

  3. 37. Fibres orientation on sawn surfaces : Can fibre orientation on sawn surfaces be determined by means of high resolution scanning

    Magister-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Andreas Briggert; [2014]
    Nyckelord :Norway spruce; fibre orientation; sawn surfaces; modulus of elasticity;

    Sammanfattning : In 2013 the European journal of wood and wood products published an article regarding a new method to predict strength in structural timber (Olsson et al 2013). By determining the fibres orientation on all four surfaces of each board in sample of timber using a high resolution scanner the authors were able to achieve a coefficient of determination, R2, as high as 0.

  4. 38. Kilohertz electro-optics for remote sensing of insect dispersal

    Master-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Sandra Török; [2013]
    Nyckelord :LUMBO; remote sensing; dark-field spectroscopy; insect wingbeat modulation; Technology and Engineering;

    Sammanfattning : This thesis evaluates the possibilities of determining the flight direction of insects by analysing the wingbeat modulation pattern of the backscattered sunlight from insects. The Lund University Mobile Biosphere Observatory (LUMBO) was used during the summer of 2013 for a field campaign at two locations in Skåne, Sweden. LÄS MER

  5. 39. Acoustic properties of porous materialsused in silencers

    Master-uppsats, KTH/Farkost och flyg

    Författare :Jesper Kristoffersson; [2013]
    Nyckelord :;

    Sammanfattning : The aim of this master thesis is an experimental investigation of the acoustic characteristics of absorbing materials used in mufflers for trucks and cars. The difference in the composition between different wool type materials consists of difference in material, fibre diameter, length, density and fibre orientation. LÄS MER

  7. 40. Characterization of Protein Surface Interactions : Collagen and Osteocalcin

    Master-uppsats, Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Författare :Patrik Johansson; [2013]
    Nyckelord :Osteocalcin; Collagen; SFG; ToF-SIMS; XPS; AFM; Orientation; Surface;

    Sammanfattning : This work investigates how the proteins collagen type I and human osteocalcin interact with various surfaces. A pH-series of collagen adsorbed onto methyl terminated self-assembled monolayers has been made and the results indicate that less tropocollagen is found on the surfaces at pH below 6. LÄS MER
