  1. 1. Study of the in-flight calibration of theSVOM/ECLAIRs instrument

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Jakob Östberg; [2020]
    Keywords : Telescope; calibration; gamma-ray; burst; ECLAIRs; SVOM; IRAP;

    Abstract : The Space based multi-band Variable astronomical Object Monitor (SVOM) is a x- andgamma-ray telescope with the primary objective of observing gamma-ray bursts. Themission is a cooperation between the French and Chinese space agencies and will be launchedin 2021. READ MORE

  2. 2. Understanding the effect of temperature and time on Gamma prime coarsening for Nickel-base superalloy Haynes 282

    University essay from KTH/Materialvetenskap

    Author : Kevin Vattappara; [2019]
    Keywords : Haynes 282; gamma prime 𝛾′ ; Arc-heat treatment; COMSOL modelling; isothermal transformation; coarsening; Thermo-Calc simulations;

    Abstract : Haynes 282 is a gamma prime (𝛾′)-strengthened nickel base superalloy developed in 2005, exhibiting a good combination of high temperature properties and fabricability. Microstructural features such as 𝛾′ and carbides play an important role in deriving the mechanical properties of the alloy during heat treatment. READ MORE

  3. 3. Study of neural correlates of attention in mice with spectro-spatio-temporal approaches

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Cantin Ortiz; [2018]
    Keywords : gamma; bursts; neuroscience; attention; mice; LFP; gamma bursts; local field potential; phase randomization; cognition; cognitive process; modulation; spike; neuron; prefrontal cortex; PFC; pre-frontal; tetrode; filtering; Hilbert transform; recordings; oscillation; gamma band;

    Abstract : While signatures of attention can be observed in widespread areas within and outside of cortex, the control of attention is thought to be regulated by higher cognitive brain areas, such as the prefrontal cortex. In their recent study on mice Kim et al. READ MORE

  4. 4. Analysis of triple gamma coincidences for studies of the level structure of nuclei in the 100-Sn region

    University essay from Uppsala universitet/Kärnfysik

    Author : Ludvig Hallberg; [2017]
    Keywords : ;

    Abstract : In this master thesis a thorough analysis of data collected in an experiment performed at the JYFL accelerator laboratory in Finland using a reaction with a 47-Ti beam on a 58-Ni target is presented. The prompt emitted gamma rays from the fusion-evaporation products were detected in the gamma-ray spectrometer JUROGAM II, while the recoils were detected in the GREAT spectrometer. READ MORE

  5. 5. Characterization of Terahertz Radiation Generated in an Organic Crystal

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Åsa Bengtsson; [2016]
    Keywords : Nonlinear optics; Terahertz radiation generation; Optical rectification; Difference frequency generation; Organic crystal; DSTMS; Physics and Astronomy;

    Abstract : The terahertz region of the electromagnetic spectrum is an important research area allowing insights into fundamental science such as inter-molecular interactions, and with applications in the environmental, medical and security field. Using femtosecond lasers, it is possible to design compact and efficient terahertz generation schemes, resulting in few-cycle broadband pulses. READ MORE
