Voluntary vertical saccades were recorded in five normal human subjects with electro-oculography (EOG), an infrared, limbus tracking system (IR), and a magnetic scleral search coil method. The peak velocity-amplitude relationships of up and down saccades were measured during refixations across the center of the orbit and within the upper and lower fields of(More)
Frequency mapping methodology is an effective diagnostic tool for detection of manufacturing defects in scan chains. It analyses reflected laser modulations from toggling scan cells to localize defective scan path or scan cell. In this paper, we demonstrate experimentally that the use of solid immersion lens technology to enhance signal and spatial(More)
This study investigates the effects of two different catalytic activation techniques on the thermal performance of the flip-chip heat spreaders. The two activation techniques studied are thin nickel–copper strike and galvanic initiation. Thermal diffusivity and surface roughness of these heat spreaders were studied using the Nano-flash Apparatus and(More)
A low frequency ν < 30 MHz spectrometer capable of noninvasively and nondestructively screening the diamagnetic properties of full intact bottles of wine is described, and along with principal component analysis, used to compare and contrast sealed bottles of wine. The sensitivity of this approach to various ionic and molecular wine solutes is established(More)
The time dependent variation of parameters solution to the time dependent Schrödinger equation pioneered by Dirac, Frenkel, and McLachlan is described in terms useful for immediate application to complex time dependent problems in magnetic resonance. A benchmark comparison of the theory to one dimensional images and spin echo envelope signals in simple(More)
A ν<25 MHz low frequency spectrometer capable of noninvasively and nondestructively screening the dielectric properties of full intact bottles of wine is described, and along with principal component analysis, used to screen rare wine. The sensitivity of this full bottle method to various ionic and molecular wine solutes was established by analyzing(More)
A bivariate correlated Student distribution is applied to full wine bottle diamagnetic screening measurements. Previous work involving a limited number of rare wines indicated that like wines cluster in a plot of the first two principal component scores derived from a covariance matrix of the diamagnetic screening measurements. This study extends the(More)
We report a method to convert, on demand, a general use dual-broadband probe to a high performance mass-limited probe for both high band and low band nuclei. This technology uses magnetic coupling of inductors to achieve this capability. The method offers a cost effective way of increasing the performance of routine NMR probes without having to change(More)
