Energy and Data Conversion Circuits for Low Power Sensory Systems
(2013)This dissertation focuses on the problem of increasing the lifetime of wireless sensors. This problem is addressed from two different angles: energy harvesting and data compression. Energy harvesting enables a sensor to ... -
Exploratory identification of introductory algebra-based physics success factors
(University of Missouri-Kansas City, 2011-06-08)The field of physics suffers from low student matriculation through its degree programs as well as being viewed as being abstract, complicated, and incomprehensible by students enrolled in introductory courses. A study was ... -
First-Principles Calculation of Laser Crystal Multiplet Levels via Hybridized Density Functional Theory and Configuration Interaction within the OLCAO Method
(University of Missouri--Kansas City, 2017)Computation of highly-localized multiplet energy levels of transition metal dopants is essential to the design of materials such as laser host crystals. A purely first-principles density functional theory-configuration ... -
Frequency and Field Strength Materials Characterization with Complementary Split-ring Resonators, Coplanar Waveguides, and the Virtual Ground Method
(University of Missouri -- Kansas City, 2019)In the radiofrequency bands, measuring the power-dependent complex permittivity and permeability of materials that undergo metal–insulator transitions is a significant challenge which is important for defense and ... -
Generalized Koszul Properties of Commutative Local Rings
(2014)We study several properties of commutative local rings that generalize the notion of Koszul algebra. The properties are expressed in terms of the Ext algebra of the ring, or in terms of homological properties of powers ... -
