New Phenomenological Constraints on the Gaugino Mediation Model
(Master thesis, 2016-05-31)In this thesis, phenomenological consequences of the Gaugino Mediation model for SUSY breaking are explored. First, the very important trilinear coupling is proven to exist in Gaugino Mediation. Then, the parameter space ... -
A new population of Terrestrial Gamma-ray Flashes
(Master thesis, 2017-06-21)Terrestrial Gamma-ray Flashes (TGFs) consist of large numbers of highenergy photons produced in thunderstorms in connection with the lightning flash, and are the most energetic photon phenomenon naturally occurring on ... -
A new population of terrestrial gamma-ray flashes in the RHESSI data
(Peer reviewed; Journal article, 2015-12-23)Terrestrial gamma-ray flashes (TGFs) are the most energetic photon phenomenon occurring naturally on Earth. An outstanding question is as follows: Are these flashes just a rare exotic phenomenon or are they an intrinsic ... -
New WMO Certified Megaflash Lightning Extremes for Flash Distance and Duration Recorded from Space

New, spherical solutions of non-relativistic, dissipative hydrodynamics
(Journal article; Peer reviewed, 2022)We present a new family of exact solutions of dissipative fireball hydrodynamics for arbitrary bulk and shear viscosities. The main property of these solutions is a spherically symmetric, Hubble flow field. The motivation ... -
Nitric Oxide Response to the April 2010 Electron Precipitation Event: Using WACCM and WACCM‐D With and Without Medium‐Energy Electrons
(Peer reviewed; Journal article, 2018-06-07)Energetic electrons from the magnetosphere deposit their energy in the atmosphere and lead to production of nitric oxide (NO) in the mesosphere and lower thermosphere. We study the atmospheric NO response to a geomagnetic ... -
NMR measurements of wettability alternation in Berea Sandstone
(Master thesis, 2011-11-28)When a new oil reservoir is discovered and a production strategy is chosen the knowledge about wettability characteristics for the field is of outermost importance. Wettability is a key factor for fluid distribution and ... -
Noise and Cluster Size Studies of ALPIDE-CMOS Pixel Sensor for pCT
(Master thesis, 2018-07-04)The use of proton beam has been introduced in medical physics for therapeutic purposes in cancer treatment and it has been proven much more efficient than conventional X-ray. Treatment planning in proton therapy is usually ... -
Non-invasive studies of multiphase flow in process equipment. Positron emission particle tracking technique
(Peer reviewed; Journal article, 2017)Positron emission particle tracking (PEPT) is a novel experimental technique for non-invasive inspection of industrial fluid/particle flows. The method is based on the dynamic positioning of a positron-emitting, flowing ... -
Non-linear flow modes of identified particles in Pb-Pb collisions at √sNN = 5.02 TeV
(Journal article; Peer reviewed, 2020)The pT-differential non-linear flow modes, v4,22, v5,32, v6,33 and v6,222 for π±, K±, K0S , p + p¯¯¯, Λ + Λ¯¯¯¯ and ϕ-meson have been measured for the first time at sNN−−−√ = 5.02 TeV in Pb-Pb collisions with the ALICE ... -

A Nonlinear Differential Equation Solver With Potential Application to Pelton Turbines
(Doctoral thesis, 2016-05-02)The focus in this thesis is the development and implementation of a new method for solving nonlinear differential equations on a grid. The method’s novelty lies in the way it represents continuously distributed variables ... -
Nonlinear echoes from encapsulated antibubbles
(Peer reviewed; Journal article, 2015-09-19)An antibubble consists of a liquid droplet, surrounded by a gas, often with an encapsulating shell. Antibubbles of microscopic sizes suspended in fluids are acoustically active in the ultrasonic range. Antibubbles have ... -
The nonlinearities in the galvanostatic charging curves of supercapacitors provide insights into charging mechanisms
(Journal article; Peer reviewed, 2022)Supercapacitors are often charged using constant currents. The capacitance can be determined from the slope of the voltage-time curve if the measured voltage over the supercapacitor increases linearly with time. However, ... -
North-south asymmetries in cold plasma density in the magnetotail lobes: Cluster observations
