This thesis presents one of the first unbiased investigations of the first- and second-generation gas-rich dwarf galaxy populations of nearby interacting groups. Individually, these low-mass objects offer information about ...

The final results of the PICASSO experiment, with 409 kg days of exposure collected from November 2012 to January 2014, have yielded new limits for Spin-Dependent and Spin-Independent Dark Matter interactions.\\ The ...

Analytical models that describe the electromagnetic field interactions arising between field generating and sensing coils in close proximity to conducting structures can be used to enhance analysis and information extracted ...

Nondestructive testing is a critical aspect of component lifetime management. Nuclear steam generator (SG) tubes are the thinnest barrier between irradiated primary heat transport system and the secondary heat transport ...

Laser keyhole welding is an emerging materials processing technique offering many advantages over more conventional joining methods. High intensity laser light is applied to a sample, melting and evaporating the metal in ...

Rare-event searches, such as the direct detection of dark matter, of neutrinoless double beta decay and of the decay of long-lived radioisotopes, require highly-sensitive radio-pure detectors to measure extremely rare ...

Photonic crystal slabs coupled with quantum dipole emitters allow one to control quantum light-matter interactions and are a promising platform for quantum information science technologies; however their development has ...

The high relative efficiency demonstrated in dye-sensitized solar cells (DSSCs) arises from a combination of light scattering within, and photo-generated electron transport through, the porous structure of a TiO2 anodes. ...

Metal-based laser additive manufacturing techniques such as selective laser melting offer unique capabilities in the manufacture of geometrically complex metal components. The ability of these techniques to fabricate unique ...

The DEAP-3600 dark matter search experiment uses 3600 kilograms of liquid argon as a target medium contained in a spherical acrylic vessel. Particle interactions in liquid argon produce vacuum ultraviolet light at a peak ...
