In this age of globalization, to survive, organizations need a good capacity retain, develop, organize and utilize their knowledge assets. The an organization comprises professional intellect, such as know‐how, know‐why, self‐motivated creativity; also the experience, concepts, values, beliefs ways working that can be shared communicated. Knowledge Management (KM) is described management organization’s through processes creating, sustaining, applying, sharing renewing enhance organizational...

Acoustic vector sensor (AVS) measures acoustic pressure as well the particle velocity to estimate intensity. The intensity, which is a quantity, represents magnitude and direction of active or propagating part an field, thus indicating direction-of-arrival (DOA) received signal. This article proposes higher order statistics (HOS)-based DOA estimation with single in underdetermined case where number sources more than sensors constituting sensor. use HOS allows increase degrees freedom,...

Acoustic Vector Sensors are underwater sensors that measure acoustic pressure as well the particle velocity to estimate intensity. The intensity, which is a vector quantity, represents magnitude and direction of active or propagating part an field thus indicating DOA(Direction arrival) received signal. This paper dwells on Iterative Adaptive Approach(IAA) for DOA signal power estimation emissions, using single sensor, significance in several passive surveillance applications. proposed IAA...

Acoustic Vector Sensors (AVS) measure acoustic pressure as well the particle velocity to estimate intensity. The intensity, which is a vector quantity, represents magnitude and direction of active or propagating part an field thus indicating Direction Arrival (DOA) received signal. This paper concerns with feasibility DOA estimation single sensor in under-determined case where number sources are more than sensors.

Directional underwater sensors have two appealing capabilities; the ability to selectively reject noise emitted from discrete interfering sources and localize, track, range targets using suitable signal processing algorithms. Specifically, "acoustic vector sensors" are directional that measure acoustic pressure as well particle velocity estimate intensity. The intensity which is a quantity represents magnitude direction of active or propagating part an field thus indicating DOA (Direction...

Acoustic Vector Sensors measure acoustic pressure as well the particle velocity to estimate intensity. The intensity, which is a vector quantity, represents magnitude and direction of active or propagating part an field thus indicating DOA (Direction arrival) received signal. Cumulant based beamforming estimation methods suitable for identification extraction desired non-gaussian signal in presence gaussian interferences and/or noise have been investigated compared against covariance...

Marine regions which dominate the surface of Earth have a pivotal role in various aspects life. It is, therefore, imperative that marine and activities thereof be examined, planned controlled for overall benefit. Spatial Planning (MSP) is related to economy, ecology environment involves planning segregation areas use considering dynamics. Key elements this are vessels traverse can monitored using Automatic Identification System (AIS). To analyse AIS data, steps need undertaken, range from...

Spatial correlation effects are analyzed in a laser near and below its threshold of oscillation by integrating the modifications function intensity fluctuations related parameters. The pump parameter is shown to depend on field spatial coherence which arise due transverse-mode structure implying spectrum time domain. \textcopyright{} 1996 American Physical Society.
