The LINK-16 standard for military anti-jam digital communications provides Anti-Jam (AJ) communications using Frequency Hop and Pseudo Noise (PN) spreading techniques. As a result, there are accurate time-of-arrival (TOA) measurements between the transmitting terminals. This paper describes the design and development of an integrated navigation filter that is capable of exploiting LINK-16 TOA m...

Localization of Wireless Capsule Endoscope (WCE) inside the small intestine is a very challenging problem, which is very important for the diagnosis of certain diseases. Previous studies have shown that Time-of-Arrival (TOA) localization can be more effective than Received Signal Strength (RSS) based localization. Performance evaluation of TOA-based localization techniques for WCE requires unde...

[1] Global simulations of sea salt and mineral dust aerosols are integrated into a previously developed unified general circulation model (GCM), the Goddard Institute for Space Studies (GISS) GCM II0, that simulates coupled tropospheric ozone-NOxhydrocarbon chemistry and sulfate, nitrate, ammonium, black carbon, primary organic carbon, and secondary organic carbon aerosols. The fully coupled ga...

A novel alkaliphilic Nocardiopsis sp., strain TOA-1, was isolated from a tile-joint of a bathroom. Strain TOA-1 produced a variety of alkaline hydrolytic enzymes. An alkaline protease, designated NAPase, was purified and characterized. NAPase had a very high keratinolytic activity and high stability under acidic conditions.

OBJECTIVE The purpose of this retrospective study was to compare the clinical outcome and characteristics of pelvic inflammatory disease (PID) complicated by tubo-ovarian abscess (TOA) with PID without TOA. METHODS Chart reviews were performed for all PID admissions to the University of Medicine and Dentistry of New Jersey-University Hospital, Newark, NJ, from January 1, 1992, to December 31,...

Because of the good penetration into many common materials and inherent fine resolution, Ultra­ Wideband (UWB) signals are widely used in remote ranging and positioning applications. On the other hand, because of the high sampling rate, coherent Time of Arrival (TOA) estimation algorithms are not practical for low cost, low complexity UWB systems. In order to improve...

High-resolution time of arrival (TOA) estimation techniques have great promise for the high range resolution required in recently developed radar systems. A widely known super-resolution TOA estimation algorithm for such applications, the multiple-signal classification (MUSIC) in the frequency domain, has been proposed, which exploits an orthogonal relationship between signal and noise eigenvec...

BACKGROUND/PURPOSE Controversy exists regarding the need for surgical intervention in patients with tubo-ovarian abscess (TOA). This study was aimed at investigating the clinical characteristics and treatment outcomes in patients with TOA at a tertiary care hospital in Taiwan. METHODS The medical records of 83 patients who presented at the hospital with TOA between January 1, 2006, and Decemb...

The high-resolution measurements of the spectral solar irradiance (SSI) at the top of the Earth’s atmosphere by the Solar Radiation and Climate Experiment (SORCE) satellite are used to examine the magnitude and spectral distribution of the Earth’s entropy flux from the TOA incident solar radiation. Two extreme cases are examined by using Planck expression: I. isotropic hemispheric incident sola...

Measurements of black carbon (BC) concentration have long been uncertain. Neither a BC standard or a technique that provides a reliable measurement of BC exist, which precludes the evaluation and optimization of BC measurement methods. In this manuscript, we describe the generation of BC particles (mass absorption efficiency 8.5m g 1 and single scattering albedo 0.2 at 530 nm) using an inverted...
