I hereby declare that I am the sole author of this thesis. This is the true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. Abstract Part of a cutover bog in Pokesudie Island, New Brunswick, Canada was contaminated with seawater and was still largely devoid of vegetation 5 ye...
Beam pipes of high-energy superconducting colliders require a shielding tube (liner) with pumping slots to screen cold chamber walls from synchrotron radiation. Pumping slots in the liner walls are required to keep high vacuum inside the beam pipe and provide for a long beam lifetime. As previously discussed [Fedotov and Gluckstern, Phys. Rev. E 54, 1930 (1996)], for a long narrow slot whose le...
Iris recognition has received increasing attention in recent years as a reliable approach to human identification. This paper makes an attempt to analyze the local feature structure of iris texture information based on the relative distance of key points. When preprocessed, the annular iris is normalized into a rectangular block. Multi-channel 2-D Gabor filters are used to capture the iris text...
This paper describes an X-Band RF system for the Next Linear Collider Test Accelerator.[1] The RF system consists of a 90 MeV injector and a 540 MeV linac. The main components of the injector are two low-Q singlecavity prebunchers and two 0.9-m-long detuned accelerator sections. The linac system consists of six 1.8-mlong detuned and damped detuned accelerator sections powered in pairs. The rf p...
We describe a framework for estimating Hilbert–Samuel multiplicities pairs of projective varieties from finite point samples rather than defining equations. The first step involves proving that this multiplicity remains invariant under certain hyperplane sections which reduce to and curve . Next, we establish equals the Euler characteristic (and hence cardinality) complex link in Finally, provi...
Microchannels typically have rectangular cross-sections, whereas biological channels, such as blood vessels and airways, circular cross-sections. The difference in cross-sections causes different fluidic behaviors, resulting differences between behavior microchannels channels. To simulate vitro, cross-sectional are required. We developed a microchannel with smooth channel wall, free from cracks...

In the present paper problem of vortex images in annular domain between two coaxial cylinders is solved by q-elementary functions. We show that all images are determined completely as poles of q-logarithmic function, where dimensionless parameter q = r 2/r 2 1 is determined by square ratio of the cylinder radiuses. The resulting solution for the complex potential is represented in terms of the ...
We propose the implementation of a Josephson radiation comb generator (JRCG) based on an extended Josephson junction subject to a time dependent magnetic field. The junction critical current shows known diffraction patterns and determines the position of the critical nodes when it vanishes. When the magnetic flux passes through one of such critical nodes, the superconducting phase must undergo ...
