This thesis presents new, compact configurations for RF/microwave bandstop and lowpass filters for embedded passive applications. A simple design methodology is presented for designing the folded-transmission line filters on a microstrip platform. Unlike the conventional stub-loaded filter designs, the proposed folded-line filters will have practical dimensions for a wide range...
Additive manufacturing has become a promising method for the fabrication of inexpensive, green, flexible sensors and electronics. Printed electronics on low- temperature substrates are very appealing for the flexible hybrid electronics market for their use in disposable and biocompatible electronic applications and in areas like packaging, wearables, and consumer electronics....
Recent trends in CMOS technology and scaling of devices clearly indicate that leakage power in digital circuits would be crucial and largely depend on the sub-threshold current.
Minimizing leakage is gaining increasing importance along with other critical design aspects primarily due to the growing demand for portable battery-operated electronic devices...
Jointed goatgrass (Aegilops cylindrica Host; 2n=4x=28; CCDD) is an
agriculturally important species both as a weed and as a genetic resource for
wheat (Triticum aestivum L.; 2n=6x=42; AABBDD) improvement. In order to
better understand the evolution of this species, the diversity of Ae. cylindrica
was evaluated along with its progenitors,...
Photoelectric and Compton interactions are some of the common interaction mechanisms we observe when gamma radiation interacts with matter. These interactions are highly depended on the energy of the radiation and the atomic number of the detector material. Lower the energy of the photon and higher the atomic number of...
The Comprehensive Nuclear-Test-Ban Treaty (CTBT) prohibits the testing of nuclear weapons on the face of the earth. The detection of atmospheric radioxenon (131mXe, 133m/133Xe, and 135Xe) plays an important role in the identification of sub-surface clandestine nuclear weapon explosions. Since the radioxenon identified above decay via two radiation in coincidence,...
This paper discusses the design strategies for interface of bus
architectures. It also describes the design of interface between the
two popular bus architectures, the Micro Channel and the Nu Bus.
The main objective of this thesis is to develop a procedure for
bus interface design and use this procedure...
Water-atomized and gas-atomized 17-4 PH stainless steel powder were used as feedstock in selective laser melting process. Gas atomized powder revealed single martensitic phase after printing and heat treatment independent of energy density. As-printed water atomized powder contained dual martensitic and austenitic phase regardless of energy density. The H900 heat...
Rapid and sensitive detection of stress hormones, such as cortisol and dehydroepiandrosterone (DHEA), can benefit the diagnosis of diseases related to adrenal gland disorders, post-traumatic stress disorders, chronic fatigue syndrome, and more. Stress hormones fluctuate in a circadian rhythm, the highest in the early morning and the lowest at night;...
We demonstrate a four-channel on-chip true-time-delay module based on a photonic crystal waveguide array. Using the photonic crystal taper to minimize the coupling loss, the delay lines with 1-3 mm long photonic crystal waveguides can operate up to a group index n(g) similar to ~23 without significant loss. The large...
