(Texas A&M University, 2004-09-30)Chloride is a deleterious ionic species in cooling water systems because it is important in promoting corrosion. Chloride can be removed from cooling water by precipitation as calcium chloroaluminate using ultra-high lime ...
-
(2019-04-03)Laser-induced breakdown spectroscopy (LIBS) is a technique that utilizes intense laser pulses to generate a localized plasma that can be used for chemical analysis via quantifying the elemental composition of a sample. ...
-
(2019-04-02)Fuel cells are attractive alternative energy sources due to their low-to-moderate operating temperature, zero greenhouse emission, and wide range of applications including automobiles and stationary power sources. However, ...
-
(2016-01-27)Two of the most critical components in an Internet-of-Things (IoT) sensing and transmitting node are the power management unit (PMU) and the wireless transmitter (Tx). The desire for longer intervals between battery ...
-
(2020-07-24)A 220 nA ultra-low quiescent bias current capacitor-less low drop-out (CL-LDO) regulator with improved single transistor control (STC) and adaptive transformation is presented in this thesis. The STC-LDO handles light load ...
-
(2019-04-01)Hydrogels, crosslinked hydrophilic polymer networks, are widely used as biomaterials because of their similarity to soft biological tissues; however, their poor mechanical properties greatly limit their utility. This work ...
-
(2023-04-04)An ultra-wideband (UWB) mm-Wave low noise amplifier (LNA) suitable for use in high performance broadband wireless communication networks is proposed. The LNA is a key building block in any wireless receiver, and there is ...
-
(Texas A&M University, 2006-10-30)This dissertation introduces new and simple techniques for suppression of multispurious passbands, which are inherent to the conventional microstrip parallel coupleline bandpass filters. In addition, the operation of ...
-
(2010-01-14)With the escalating number of vehicles on the road, great concerns are drawn to the large amount of fossil fuels they use and the detrimental environmental impacts from their emissions. A lot of research and development ...
-
(2012-07-16)Technological progress in commercializing ultrafast lasers and detectors has allowed realization of cooperative processes on an ultrashort time scale, which demand a re-evaluation of the conventional cooperative phenomena ...
-
(2018-11-28)A comprehensive thermo-elasto-plastodynamic model of the laser-material interaction in polycrystalline metals in response to ultrafast laser heating is formulated. Lacking a fundamental understanding for the non-ablation ...
-
(2011-02-22)A comprehensive model for describing the fundamental mechanism dictating the interaction of ultrafast laser pulse with single crystalline silicon wafer is formulated. The need for establishing the feasibility of employing ...
-
(2013-12-11)This dissertation is devoted to ultrafast waveform synthesis using coherent Raman sidebands with the assistance of pulse shapers based on acousto-optic programmable dispersive filter (AOPDF) or deformable mirror (DM). ...
-
(2022-06-27)Air pollution, including gases, metals, and airborne particles (particulates) can pose a significant risk to public health, and collectively cause many different types of toxicity. Over recent years, toxicology research ...
-
(2016-12-19)The promise of solar powered energy is highly attractive, generating research efforts into the physical understanding of photovoltaic devices and how a greater knowledge of these systems can be applied to improving their ...
-
(2011-02-22)An ultrametric field is a field that is locally compact as a metric space with respect to a non-archimedean absolute value. The main topic of this dissertation is to study roots of polynomials over such fields. If we ...
-
(Texas A&M University, 2005-02-17)The petroleum industry is in a constant state of change. Few industries have advanced as far technologically as the petroleum industry has in its relatively brief existence. The produced products in the oil and gas industry ...
-
(2011-08-08)NV centers in a diamond are proving themselves to be good building blocks for quantum information, electron spin resonance (ESR) imaging, and sensor applications. The key feature of the NV is that it has an electron spin ...
-
(2010-01-16)We simulate ultrashort pulse propagation through water by numerical methods, which is a kind of optical communication research. Ultrashort pulses have been known to have non Beer-Lambert behavior, whereas continuous waves ...
-
(2010-07-14)First, we investigate the Bouguer-Lambert-Beer (BLB) law as applied to the transmission of ultrashort pulses through water in the linear absorption regime. We present a linear theory for propagation of ultrashort laser ...
