V^2 power converter control with capacitor current ramp compensation
(United States Patent and Trademark Office, 2017-03-21)Operation of a switching power converter having an output capacitor having a small equivalent series resistance (ESR) is stabilized and jitter reduced by sensing capacitor current with gain and combining the resulting ... -
Virtual Secure Circuit: Porting Dual-Rail Pre-charge Technique into Software on Multicore
(Cryptology ePrint Archive, 2010)This paper discusses a novel direction for multicore cryptographic software, namely the use of multicore to protect a design against side-channel attacks.We present a technique which is based on the principle of dual-rail ... -
Visibility-Dependent Depth Of Focus For Incoherent Sinusoidal Sources
(Optical Society of America, 1992-05-01)A visibility-dependent depth of focus is developed for incoherent sinusoidal sources. This analysis is based on a derived relationship between the visibility and the optical transfer function (OTF). The formalism developed ... -
Void-mediated coherency-strain relaxation and impediment of cubic-to-hexagonal transformation in epitaxial metastable metal/semiconductor TiN/Al0.72Sc0.28N multilayers
(2017-08-17)Bulk metastable phases can be stabilized during thin-film growth by employing substrates with similar crystal structure and lattice parameter, albeit over a thickness range limited by coherency-strain relaxation. Expanding ... -
Volatile resistive switching in Cu/TaOx/delta-Cu/Pt devices
(AIP Publishing, 2012-08-01)A volatile switching of conductive filament (CF) in a Cu/TaOx/delta-Cu/Pt device has been observed. The device differs from a conventional Cu/TaOx/Pt device by the insertion of a thin Cu-layer (delta-Cu) between the ... -
Wavelet Based ULF Pulsation Index for Studying Conjugate ULF Pulsation at High Latitudes and Its Applications to Space Weather
(2016-12-14)A wavelet-based index is described in this study and applied to present geomagnetic Ultra Low Frequency (ULF) pulsations observed in Antarctica and their magnetically conjugate locations in West Greenland. The index is ... -
Wearable Accelerometer and sEMG-Based Upper Limb BSN for Tele-Rehabilitation
(MDPI, 2019-07-12)Assessment of human locomotion using wearable sensors is an efficient way of getting useful information about human health status, and determining human locomotion abnormalities. Wearable sensors do not only provide the ... -
Whole Exome Sequencing to Identify Genetic Variants Associated with Raised Atherosclerotic Lesions in Young Persons
(Springer Nature, 2017-06-22)We investigated the influence of genetic variants on atherosclerosis using whole exome sequencing in cases and controls from the autopsy study "Pathobiological Determinants of Atherosclerosis in Youth (PDAY)". We identified ... -
Wide scanning spherical antenna
(United States Patent and Trademark Office, 1995-10-17)A novel method for calculating the surface shapes for subreflectors in a suboptic assembly of a tri-reflector spherical antenna system is introduced, modeled from a generalization of Galindo-Israel's method of solving ... -
Winds and tides in the mid-latitude Southern Hemisphere upper mesosphere recorded with the Falkland Islands SuperDARN radar
(Copernicus Publications, 2011)Meteor wind data from the first year of operation of the Falkland Islands SuperDARN radar (52 degrees S, 59 degrees W) are used to characterize the atmospheric tides and background winds in the upper mesosphere above the ... -

X-ray and XPS studies of evaporated cuxs thin-films
(American Institute of Physics, 1983-04-01)The structural changes in Cu x S films have been monitored by x_ray diffraction and correlated to the chemical changes taking place on the Cu x S surface, the latter monitored by XPS. The results show: evaporated Cu x S ... -
X-Ray Phase-Contrast Imaging with Three 2D Gratings
(Hindawi, 2008-03-24)X-ray imaging is of paramount importance for clinical and preclinical imaging but it is fundamentally restricted by the attenuation-based contrast mechanism, which has remained essentially the same since Roentgen's discovery ... -
Zero-current transition PWM converters
(United States Patent and Trademark Office, 1996-01-23)A zero-current transition pulse-width modulated (ZCT-PWM) d.c.-d.c. converter allows minority-carrier semiconductor devices such as, for example, bipolar junction transistors (BJTs), insulated gate bipolar transistors ... -
ZrO2 Thin-Film-Based Sapphire Fiber Temperature Sensor
(Optical Society of America, 2012-10-01)A submicrometer-thick zirconium dioxide film was deposited on the tip of a polished C-plane sapphire fiber to fabricate a temperature sensor that can work to an extended temperature range. Zirconium dioxide was selected ...
