Intelligent Detection and Recognition of Marine Plankton by Digital Holography and Deep Learning

Sensors
The detection, observation, recognition, and statistics of marine plankton are the basis of marine ecological research. In recent years, digital holography has been widely applied to plankton detection and recognition.

Holographic complexity and volume

Journal of High Energy Physics, 2018
The previously proposed “Complexity=Volume” or CV-duality is probed and developed in several directions. We show that the apparent lack of universality for large and small black holes is removed if the volume is measured in units of the maximal time from

The investigation of volume change of photopolymerization by holography.

Journal of Photopolymer Science and Technology, 1992
The volume of a photopolymerizable medium may be changed after monomer is converted into polymer. One has not yet precise method for measuring a volume change when a photopolymerization reaction occurs in a film. This paper proposes a holographic method for measuring the volume change (that is the thickness change) of a photopolymerizable film.

Braneworld holography in Gauss-Bonnet gravity

, 2003
We investigate holography on an (n-1)-dimensional brane embedded in a background of AdS black holes, in n-dimensional Gauss-Bonnet gravity. We demonstrate that for a critical brane near the AdS boundary, the Friedmann equation corresponds to that of the ...

Extensivity Versus Holography in Anti-de Sitter Spaces [PDF]

, 1998
We study the dimensionality manifested in the AdS/CFT correspondence. We show that the dimensionality as expressed by the high temperature behavior of a system has a holographic nature also at the quantum level.

Holography and Rotating AdS Black Holes

, 1999
We probe the AdS/CFT correspondence by comparing the thermodynamics of a rotating black hole in five-dimensional anti-de Sitter space with that of a conformal field theory on $S^3$, whose parameters come from the boundary of spacetime.

Probing the Holography of Near-Horizon AdS(5)xS(5) Geometry [PDF]

, 2003
Using the AdS/CFT correspondence we study the holographic principle and the CFT/FRW relations in the near-horizon AdS(5)xS(5) geometry with a probe D3-brane playing the role of the boundary to this space.

Holographic mensuration of suspended particles in aquatic systems [PDF]

, 1995
The distribution and dynamics of aggregates in the aquatic environment play an important role in the modelling of biogeochemical processes. Previous work on aggregates in the ocean (e.g.

Holography in Einstein Gauss-Bonnet Gravity

, 2004
We investigate a holographic relation between Einstein Gauss-Bonnet gravity in $n$ dimensions and its dual field theory in ($n-1$) dimensions. We briefly review the AdS/CFT correspondence for the entropy in the $n$-dimensional Einstein gravity and ...

Intrinsic speckle noise in in-line particle holography due to poly-disperse and continuous particle sizes [PDF]

, 2000
In-line particle holography is subject to image deterioration due to intrinsic speckle noise. The resulting reduction in the signal to noise ratio (SNR) of the replayed image can become critical for applications such as holographic particle velocimetry ...
