Experimental Study of Proton Rate Density in a Spherical Inertial Electrostatic Confinement Fusion Device
… (C-device)--have been developed. The SIEC-TX generates x-rays by electron-electron interactions at relativistic velocity at the sphere center when the electrons are accelerated and focused by a spherical grid. The wavelength of the emitted x-rays shifts as the grid bias is changed. The C-device is …

Exploring fundamental physics and astrophysics with gravitational-wave sources
… to 𝑧 ∼ 100, and hence tracing the cosmic merger rate history may become feasible. There are two intriguing BBH populations beyond 𝑧 ∼ 10 which are unreachable by the current detectors. The first possible population consists of astrophysical BBHs originated from the remnants of Population III (Pop …

Analysis of Infinite Domain Criticality Zones in Finite Reactors (Uniform Power, Minimum Fuel Density, Exact Solutions, Poles of Bromwich Integral, Reduction of Pde's)
… large has two ideal properties: (1) The fission rate density and, hence, the power are uniform throughout, and (2) the fuel density needed for criticality is minimum. A finite reactor loaded in this way would be subcritical and would have to contain additional fuel to compensate for neutron …

Design of Latent Thermal Energy Storage Systems
… the energy flows by fluid flow from a concentrated source to points (users) distributed equidistantly on the area. The challenge in this chapter is to determine the architecture of distributed energy storage. The chief conclusion is that the finite amount of storage material should be …

The search for unmodeled gravitational-wave transients in the Advanced LIGO-Virgo Era
… to set the strictest upper limits to date on the rate-density of non-compact-binary GW transients. Finally, we turn our attention to how future improvements to the Advanced Detectors, such as squeezed-light injection, will impact the science done with GW transients.

Bayesian Analysis of Linear Inverse Problems with Applications in Economics and Finance
… this estimator to deconvolution and to hazard rate, density and regression estimation. Then, I consider the estimation of an Instrumental Regression that is useful in micro-econometrics when we have to deal with problems of endogeneity. Finally, I develop an application in finance: I get the …

Parametric and nonparametric identification of shell and tube heat exchanger mathematical model
… which involved, among others, temperature, flow rate, density and heat capacity. The identification process produces a dynamic model of the heat exchanger which is developed based on a lumped parameter system. The model developed is single input single output whereas input signal is hot water …

Influence of laser scan rate on the mechanical properties of SLM TI6AL4V alloy
… fracture toughness and fatigue crack growth rate (FCGR) properties has been investigated on samples produced by the selective laser melting (SLM) process from a Grade 5 Ti6Al4V metal powder; the laser scan speed was varied from 1.5 m/s to 4 m/s, while other process parameters were kept …

All-Sky Search for Very-High-Energy Emission from Primordial Black Holes and Gamma-Ray Bursts with the HAWC Observatory
… observes 2/3 of the sky every day. HAWC operates using the water-Cherenkov detection technique with 1,200 photomultiplier tubes (PMTs) in two different sizes to detect Cherenkov emission from secondary air-shower particles. Herein, we present an improved characterization for the larger of …

Spatially resolved star formation and quenching: insights from observations and simulations
The cosmic star formation rate density is known to have declined by a factor of ~10 to present day after reaching its peak at z ~ 2. There were drastic differences in the star-forming conditions between z ~ 0 and z ~ 2, such that galaxies in the past were more star-forming and gas-rich. Given the …

Enhancing the detection and the reconstruction of gravitational-wave transients in the LIGO-Virgo-KAGRA data using weak assumptions on the astrophysical sources
… regulators successfully reduce the false alarm rate of the HL coherent analysis, but to make full use of a third, not-aligned detector, they should be relaxed. The fifth chapter investigates the impact of the likelihood regulators in cWB for HLV network, first in a simplified case assuming …

The faint low-frequency radio universe in continuum: exploitation of the pre-SKA deepest survey
… for multiple component sources down to a 5σ flux density limit of 35.5 µ Jy. From this data, I derive the 610 MHz source counts applying corrections for completeness, resolution bias and Eddington bias. The 610- MHz source counts show a flattening at flux densities below 1 mJy. The source counts …
