In this paper, we analyze the achievable location accuracy of a high-precision localization system using time-difference-of-arrival measurements of ultra wide-band (UWB) pulses. This system is under development at our institute and based on a low-power CMOS chip. Similar commercially available localization systems achieve location accuracies (location error standard deviation) down to 15cm unde...

A small scale sample nuclear waste package, consisting of a 28mm diameter uranium penny encased in grout, was imaged by absorption contrast radiography using a single pulse exposure from an X-ray source driven by a high-power laser. The Vulcan laser was used to deliver a focused pulse of photons to a tantalum foil, in order to generate a bright burst of highly penetrating X-rays (with energy >5...

A study was conducted in the alluvial soils located in Oko-anala in Delta State, Nigeria. These alluvial soils are primarily used for intensive vegetable production for commercial purposes. The total land area of about 3.34 Square kilometer was divided into three consociations and composite soil samples collected from pre-determined depths of 0-15 and 16-30cm. The samples were routinely prepare...

Background: The purpose of this study was to examine the effect of a cognitive task on jump-landing biomechanics and performance. Methods: 26 recreational athletes participated in the study. Participants jumped forward off of a 30cm box a distance equal to one half of their body height, then immediately performed a countermovement jump. This movement was performed in a control condition, while ...

Shock Attenuation in Landing by Bryon Christopher Applequist Dr. John Mercer, Examination Committee Chair Associate Professor of Kinesiology University of Nevada, Las Vegas Shock attenuation (SA) has been well studied in activities such as walking and running (Chu, et al. 2004; Derrick, et al. 2004; Mercer, et al. 2003); however, there is a lack of research regarding SA during landing. Furtherm...

As signal to noise ratio in magnetic resonance imaging (MRI) improves with increasing static magnetic field strength there is a strong incentive to develop the technology to acquire images at higher fields. While magnet technology has made it possible to generate fields of 10 Tesla and more, limitations of the radio frequency (RF) hardware prevent the acquisition of high quality images over ful...

Purpose: To seek adequate sequence of MR angiography (MRA) on developmental venous anomaly in the brain. Material and Methods: We collected ten cases who demonstrated developmental venous anomaly on MR image. Eight patients among them, both 3D timeof-flight (TOF) with or without Gadolinium-DTPA enhancement and phase contrast(PC) were performed: TOF without enhancement in five, TOFwith enhanceme...
