Integration of a heat flux sensor and an infrared filter for fire detection
(2022)
Fire detection is based on detecting some key element of a fire, like smoke, flames or temperature. A carbon fire creates high temperature H₂O and CO₂ gases that emit distinctive infrared radiation. These radiation peaks ...
Coherent anti-Stokes Raman scattering spectromicroscopy in biomedical and climate research
(Lappeenranta-Lahti University of Technology LUT, 2022-02-24)
Coherent anti-Stokes Raman scattering spectromicroscopy (CARS SM) is a powerful label-free technique based on intrinsic molecular contrast from nuclear vibrations that provides detailed information on the chemical composition ...
Development of new persistent luminescent composites using modified direct doping method
(2022)
The principal aim of this thesis was to create novel persistent luminescent composites that display green persistent luminescence (PeL) when charged not only with UV light but also with infrared radiation. The fundamental ...
Test setup development for DeNuSa project
(2022)
The aim of this thesis is to document the test setup developed for a charge sensitive preamplifier as part of the DeNuSa project. DeNuSa or Detectors for nuclear safetym decommissioning and diagnostic applications is a ...
The Kondo effect in a quantum confined system
(2022)
Atomic-scale engineering aims to exploit quantum effects to produce tailored electronic properties. One such effect is the Kondo effect, in which a many-body correlation arises between the spin of an electron in a localized ...
Simulation and analysis of the diffusion properties of chloroform solution of carbosilane dendrimers
(2022)
Diffusion properties of macromolecules are important for theoretical studies and practical application. The hydrodynamic radius Rh, calculated from simulation data is usually used as a test of the correctness of the ...
Numerical approximations of non-linear shallow water equations
(2020)
In this work, the Finite Difference Methods (FDMs), and Method of Lines (MOL) have been used to solve the Shallow Water Equations (SWEs) in one dimension. The SWEs has a free surface with no rotation, it's kinematic viscosity ...
Smart grasping of known objects
(2020)
Smart grasping means that a robot can automatically decide which object and how an object can be grasped. Firstly, a neural network should find the objects and get a 2D bounding box. The convolution neural network is used ...
Mathematical methods in adaptive optics
(2020)
In this thesis, we made a literature review of adaptive optics in astronomy and to the mathematical methods behind it. Adaptive optics is used to correct wavefront perturbations caused by the atmosphere when imaging ...
Medical imaging applicability study of silicon pixel detectors with PSI46dig ROC
(2020)
The aim of the Multispectral Photon Counting for Medical Imaging and Beam Characterization (MPMIB) project is to develop a next-generation medical imaging detecting system capable of multispectral imaging. One of the ways ...
