    Author : Simon Trcka; [2019]
    Keywords : UAV; structure from motion; remote sensing; diameter at breast height; UAS; drone; photogrammetry; forest inventory; tree height; stem volume; stand model;

    Abstract : The master ‘s thesis focused on forest inventory process based on the photogrammetric point cloud. The study deals with forest stand data collecting using terrestrial and aerial photogrammetry. READ MORE

  4. 3. Above-ground biomass estimation in boreal productive forests using Sentinel-1 data

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : David Roc Roc; [2019]
    Keywords : synthetic aperture radar SAR ; backscatter intensity; InSAR; interferometric coherence; LIDAR; above-ground biomass; forestry;

    Abstract : Estimation of biomass has high importance for economic, ecologic and climatic reasons due to the multiple ecosystem services offered by forested landscapes. Measurements that are taken in the field incur personal and economic costs. Nevertheless, biomass surveying based on remote sensing techniques offer efficiency thanks to covering large areas.

  5. 4. Exotic Decays of a Vector-liketop Partner at the LHC

    University essay from Uppsala universitet/Högenergifysik

    Author : Alexander Skwarcan-Bidakowski; [2019]
    Keywords : Particle physics; Vector-like quarks; VLQ; Composite Higgs model; CHM; Top-partner; pseudo; Nambu-Goldstone boson; pNGB; NGB; ATLAS; LHC; CMS; Significance; Recast; CheckMate; CM; MadGraph; Pythia; Delphes; Detector; Analysis; Hierarchy Problem; Exotic; Decay; QFT; Quantum Field Theory; fermions; bosons; Jets; photons; leptons; 13 TeV; Missing Transverse Energy; momentum; hypothetical; selection criteria; Standard model; Signal; background; event; Higgs; Mechanism; Simulation; Confidence limit;

    Abstract : An evaluation of how sensitive some ATLAS searches for new physics are to a new beyond standard model (BSM) vector-like quark (VLQ) and a pseudo Nambu-Goldstone boson (pNGB) scalar. This was done by simulating a signal containing these new particles and making a recast of it onto existing verified ATLAS searches for new physics at center-of-mass (CM) energy of 13 TeV (Run 2) at the Large Hadron Collider (LHC).

  6. 5. Integration of a novel flow boundary layer sensor into a wireless sensor network with minimal space and energy consumption

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Mukul Suhas Bandodkar; [2018]
    Keywords : ;

    Abstract : Boundary layer flow measurement is one of the most important as well as a daunting task when it comes to various critical applications involving intensive fluid dynamics like measuring the flow over the wings of an aircraft or blades of a windmill placed in far deserted conditions, thus demanding the need for highly accurate and precise flow measurement units which also should be compact, energy efficient and capable of operating over a wide range of extreme temperatures. Boundary layer flow sensors are normally used to measure the flow of a fluid by measuring the convective heat transfer coefficients over a surface and thereby calculating the pressure difference and hence the velocity of the flow of the fluid.
