We analyze shallow water wind waves in Currituck Sound, North Carolina and experimentally confirm, for the first time, the presence of soliton turbulence in ocean waves. Soliton turbulence is an exotic form of nonlinear wave motion where low frequency energy may also be viewed as a dense soliton gas, described theoretically by the soliton limit of the Korteweg-deVries equation, a completely int...

This paper presents a broadband optical packet generation method by multiplexing low- and high-frequency signals using bias tee. The cut-off frequency of the tee, fc is optimized in terms eye-opening ratio for trains with different guard times intervals. As result, optimal condition observed to be fGT < f1, should closer fGT. (where f1 high-pass low-frequency amplifier). We implemented tee base...

We report an error estimate of the multi-dimensional fast Gauss transform (FGT), which is much sharper than that previously reported in the literature. An application to the Karhunen–Loeve decomposition in the three-dimensional physical space is also presented that shows savings of three orders of magnitude in time and memory compared to a direct solver. 2006 Elsevier Inc.

Debates about poverty relief and foreign aid often hinge on claims about how many poor people there are in the world and what constitutes poverty. Good measures of poverty are essential for addressing the world poverty problem. Measures of poverty require a basis for determining who is poor and a method of aggregation. Historically, the methods of aggregation were quite simple. The headcount in...

Many vision algorithms depend on the estimation of a probability density function from observations. Kernel density estimation techniques are quite general and powerful methods for this problem, but have a significant disadvantage in that they are computationally intensive. In this paper, we explore the use of kernel density estimation with the fast Gauss transform (FGT) for problems in vision....

On the basis of Lagrangian formalism of relativistic field theory post-Newtonian equations of motion for a rotating body are derived in the frame of Feynman’s quantum field gravity theory (FGT) and compared with corresponding geodesic equations in general relativity (GR). It is shown that in FGT the trajectory of a rotating test body does not depend on a choice of a coordinate system. The equat...

The study of many vision problems is reduced to the estimation of a probability density function from observations. Kernel density estimation techniques are quite general and powerful methods for this problem, but have a significant disadvantage in that they are computationally intensive. In this paper we explore the use of kernel density estimation with the fast gauss transform (FGT) for probl...

Lap time is the most relevant performance indicator in electric racing. In order to minimize it, it important carefully design powertrain of race car terms sizing and technology, meticulously administer energy available on-board. To facilitate efficient design, this paper presents a convex optimization framework rapidly compute minimum-lap-time control strategies for battery car. Specifically, ...

BACKGROUND Genital tuberculosis is a common entity in gynecological practice particularly among infertile patients. It is rare in developed countries but is an important cause of infertility in developing countries. OBJECTIVE The present study has investigated the prevalence of female genital tract tuberculosis (FGT) among infertile patients, which was conducted at the Obstetrics and Gynecolo...
