Analysis of spatial mode sensitivity of gravitational wave interferometer and targeted search for gravitational radiation from the Crab pulsar
… absorption, required the installation of a thermal compensation system. We describe a frequency resolving wavefront sensor, called the phase camera, which was used on the interferometer to examine the heating effects and corrections of the thermal compensation system. The phase camera was …

LIGO interferometer operating at design sensitivity with application to gravitational radiometry
… This required the commissioning of both a thermal compensation system and shot noise limited sensing electronics capable of detecting all the light. Additionally, a series of unexpected noise sources had to be mitigated. This work is described in the first part of this thesis. In a second …

Active wavefront correction in laser interferometric gravitational wave detectors
… method of active wavefront correction via direct thermal actuation on optical elements of the interferometer; or, "thermally adaptive optics". A simple nichrome heating element suspended off the face of an affected optic will, through radiative heating, remove the gross axisymmetric part of the …

Overcoming Thermal Challenges to Acquire Absolute Pressure Measurements in Rotating Detonation Engines Using Piezoresistive Pressure Transducers
… in recessed configuration into an RDE. Thermal compensation was effective after initial transients subsided, resulting in matching time-varying pressure from both PE and PR transducers. However, the time-averaged pressure deviated significantly from the corresponding CTAP …

Athermal photonic devices and circuits on a silicon platform
… resolution in various applications. Active thermal compensation using heaters and thermo-electric coolers are the legacy solution for low density integration. However, the required electrical power, device foot print and number of input/output (I/O) lines limit the integration density. We …

COOLING THEORY FOR THERMOPLASTIC MATERIALS USED IN SCREW EXTRUSION ADDITIVE MANUFACTURING
… to result in sagging and print failure. Print thermal behavior and temperature management are closely related to material, part design and deposition strategy. Even though numerous software solutions for predictive process simulation as well as active feedback print controls for parameters …

Real-Time Atmospheric compensation and surface temperature estimates from Satellite using Neural Networks
… these systems are highly vulnerable to thermal absorption and reemission that can affect the thermal signature prior to launch. In particular, there is a need to use additional assets to estimate the atmospheric temperature and water vapor profile so that an estimate of the atmospheric …
