Acquisition of airborne imagery in support of Deepwater Horizon oil spill recovery assessments
(2012-10-19)Remote sensing imagery was collected from a low flying aircraft along the near coastal waters of the Florida Panhandle and northern Gulf of Mexico and into Barataria Bay, Louisiana, USA, during March 2011. Imagery was ... -
Activity coefficient and the Einstein relation
(1983-07-15)A connection between the activity coefficient of current carriers and the Einstein relations is established by two methods, one based on normal semiconductor concepts and one based on irreversible thermodynamics. The ... -
An Adaptive Distributed Data Aggregation based on RCPC for Wireless Sensor Networks
(2006-05-10)One of the most important design issues in wireless sensor networks is energy efficiency. Data aggregation has significant impact on the energy efficiency of the wireless sensor networks. With massive deployment of sensor ... -
Adaptive handoff algorithms based on self-organizing neural networks to enhance the quality of service of nonstationary traffic in hierarchical cellular networks
(2000-03-30)Third-generation (3G) wireless networks, based on a hierarchical cellular structure (HCS), support tiered levels of multimedia services. These services can be categorized as real-time and delay-sensitive, or non-real-time ... -
Adaptive threshold selection technique for denoising in dithered quantizers
(2001-03-26)We described an adaptive denoising method to improve image quality in a wavelet-based image compression process that uses dithered quantization. In our method, the second-order moment of the quantization noise is ... -
Adaptive weighing of context models for lossless data compression
(2005-12-21)Until recently the state of the art in lossless data compression was prediction by partial match (PPM). A PPM model estimates the next-symbol probability distribution by combining statistics from the longest matching ... -
Adrenal gland and lung lesions in Gulf of Mexico common bottlenose dolphins (Tursiops truncatus) found dead following the Deepwater Horizon oil spill
(2015-05-20)A northern Gulf of Mexico (GoM) cetacean unusual mortality event (UME) involving primarily bottlenose dolphins (Tursiops truncatus) in Louisiana, Mississippi, and Alabama began in February 2010 and continued into 2014. ... -
An Advanced context aware operator support system (CAOSS) for chemical plant operation
(2018-05)Analyzing potential causes for recent industrial accidents and production losses highlights that the majority of these incidents are due to human factor failure: operator error, poor decision-making and violations ... -
Advanced Discrete Halanay-Type Inequalities: Stability of Difference Equations
(2009-01-21)We derive new nonlinear discrete analogue of the continuous Halanay-type inequality. These inequalities can be used as basic tools in the study of the global asymptotic stability of the equilibrium of certain generalized ... -
Advancement of an optical remote sensing model to simulate the underwater light field
(1997-01-17)An analytical solution to the two-flow equations developed by Bostater, et al. is modified, and a sensitivity analysis is performed on the remote sensing model which contains both diffuse and specular light components. The ... -
Advances in In-Situ Calibration of Attitude and Doppler Sensors for Precision Oceanographic Submersible Navigation
(2005)This paper reviews the development and experimental evaluation of three techniques for estimating the alignment matrix of Doppler sonars, which are commonly used for precision navigation of oceanographic submersibles, ... -
