Analytical Derivation of Three Dimensional Vorticity Function for wave breaking in Surf Zone [PDF]
arXiv, 2015 In this report, Mathematical model for generalized nonlinear three dimensional wave breaking equations was de- veloped analytically using fully nonlinear extended Boussinesq equations to encompass rotational dynamics in wave breaking zone. The three dimensional equations for vorticity distributions are developed from Reynold based stress equations ...

Benign and malignant cutaneous nasal lesions
Eye &ENT Research, Volume 1, Issue 2, Page 65-91, December 2024.Abstract The nose is a structure of both cosmetic and functional importance. Cutaneous lesions of the nose occasionally represent a diagnostic challenge and involve the expertise of several specialties from dermatology, otolaryngology—head and neck surgery, infectious disease, and pathology, among others.

Habitable Zones of Host Stars During the Post-MS Phase [PDF]
, 2010 A star will become brighter and brighter with stellar evolution, and the distance of its habitable zone will become farther and farther. Some planets outside the habitable zone of a host star during the main sequence phase may enter the habitable zone of the host star during other evolutionary phases.

On the multiplicity of arrangements of congruent zones on the sphere [PDF]
arXiv, 2017 Consider an arrangement of $n$ congruent zones on the $d$-dimensional unit sphere $S^{d-1}$, where a zone is the intersection of an origin symmetric Euclidean plank with $S^{d-1}$. We prove that, for sufficiently large $n$, it is possible to arrange $n$ congruent zones of suitable width on $S^{d-1}$ such that no point belongs to more than a constant ...

Exclusion and Guard Zones in DC-CDMA Ad Hoc Networks [PDF]
arXiv, 2013 The central issue in direct-sequence code-division multiple-access (DS-CDMA) ad hoc networks is the prevention of a near-far problem. This paper considers two types of guard zones that may be used to control the near-far problem: a fundamental exclusion zone and an additional CSMA guard zone that may be established by the carrier-sense multiple-access (

A Novel Solution to the ATT48 Benchmark Problem [PDF]
arXiv, 2007 A solution to the benchmark ATT48 Traveling Salesman Problem (from the TSPLIB95 library) results from isolating the set of vertices into ten open-ended zones with nine lengthwise boundaries. In each zone, a minimum-length Hamiltonian Path (HP) is found for each combination of boundary vertices, leading to an approximation for the minimum-length ...

CoZo+ - A Content Zoning Engine for textual documents [PDF]
arXiv, 2008 Content zoning can be understood as a segmentation of textual documents into zones. This is inspired by [6] who initially proposed an approach for the argumentative zoning of textual documents. With the prototypical CoZo+ engine, we focus on content zoning towards an automatic processing of textual streams while considering only the actors as the zones.

arXiv, 2012 To generate hollow chain-like beams the diffraction of the first order Bessel beam by zone plate with two odd open Fresnel zone has been investigated. It has been shown that the capsules size is influenced by the number of the second odd open Fresnel zone and by the zone plate focal length.
