Abstract:
This thesis examines the design and synthesis of a new class of biomimetic switches that replicate different aspect of the Z/E photoisomerization of rhodopsin. Theoretical studies on rhodopsin showed that a penta-2,4-dieniminium moiety is the minimal structure responsible of the photochemical properties of the visual pigment. By trapping this π system into conformational rigid molecules we synthesized NAIP (N-alkylated indanylidene-pyrroline Schiff base) switches featuring a selective and ultra-fast light-driven E/Z photoisomerization.

The number of alternative licensure programs has increased significantly over the past decade. Faced with critical shortages of public school teachers in several subject areas, the Commonwealth of Virginia first approved an alternative route to licensure in 1998. In accordance with the No Child Left Behind Act of 2001, school divisions must ensure that teachers are highly qualified and prepared for classroom teaching. While the majority of alternative licensure programs are sponsored by colleges or universities, the Commonwealth of Virginia allows school divisions to create alternative lice

Due to long lifetime in excited states, EDFAs do not oppose the effect of cross-gain saturation.

Techniques aiming to reduce machine torque ripple either compromise the machine performance or the simplicity of the inverter and the controller.

This is achieved by designing a 6-phase machine and driving it from a three-phase full bridge circuit.

Abstract:
This thesis examines the design, synthesis and testing of photobiological switches of α-chymotrypsin. A photobiological switch is a biologically active compound that incorporates a photo active group in order that light-triggered switching of the biological target is afforded. The switches described in this thesis incorporate azobenzene as the photochromic group and α-ketoester or α-ketoamide as the inhibitory moiety. A novel component of these switches is the use of peptidyl groups to enhance the specificity of α-chymotrypsin toward these compounds. Thus, there are three fundamental elements

Abstract:
The fully-pitched winding arrangement is one of the most radical changes in the design of doubly-salient reluctance motors in recent times. By replacing conventional shortpitched windings with fully-pitched windings, the resulting machine has a strong and position dependant mutual coupling between phases. The major torque producing mechanism is due to changes in mutual inductance with rotor position. This enables the windings to be better utilised, and with correct selection of excitation all phases can contribute useful torque all of the time. The increased winding utilisation requires a lowe
