Influence of the metallic nanoparticles on the arabinogalactan optical properties
Optical Memory and Neural Networks - Tập 24 - Trang 60-65 - 2015
Metallic nanoparticles are a powerful tool of modern photonics allowing one to modify and control the optical properties of materials. Arabinogalactan (AG)—a complex organic molecule, offers a convenient way for nanoparticle fabrication due to its chemical properties. In the current paper the refractive index and optical transparency of arabinogalactan and AG-nanoparticle composite was studied by ......
LaF3–Er3+ Crystal as Materials for MIR-Lasing Operating
Optical Memory and Neural Networks - Tập 32 - Trang S362-S368 - 2024
The possibilities of LaF3–Er3+crystal to obtain cascade lasing with CW pumping at 0.52 μm wavelength are considered. The conditions for the formation of inverse populations between Stark levels of neighboring manifolds are determined. It is shown that, at 100 K and CW pump intensity

Comparison of Face Recognition and Detection Models: Using Different Convolution Neural Networks
Optical Memory and Neural Networks - Tập 28 - Trang 101-108 - 2019
Face detection and recognition plays an important role in many occasions. This study explored the application of convolutional neural network in face detection and recognition. Firstly, convolutional neural network was briefly analyzed, and then a face detection model including three convolution layers, four pooling layers, introduction layers and three fully connected layers was designed. In face......
Free-space interconnect for optical switch and analogue neural network
Optical Memory and Neural Networks - Tập 20 - Trang 2-6 - 2011
In this paper, the architecture of a vector-matrix multiplier (MVM) is simulated. The optical design can be made compact by the use of GRIN lenses for the optical fan-in. The intended application area was in storage area networks (SANs) but the concept can be applied to a neural network.

Near-wall liquid flows visualization on frustrated total internal reflection
Optical Memory and Neural Networks - Tập 18 - Trang 322-327 - 2010
An experimental setup for near-wall liquid flows visualization is described. The refraction index measurement sensitivity and other setup parameters is optimized. The experimental results for three example of liquid are presented: glycerin, sugar and salt water solution.
Fast online algorithm for nonlinear support vector machines and other alike models
Optical Memory and Neural Networks - Tập 25 - Trang 203-218 - 2017
Paper presents a unique novel online learning algorithm for eight popular nonlinear (i.e., kernel), classifiers based on a classic stochastic gradient descent in primal domain. In particular, the online learning algorithm is derived for following classifiers: L1 and L2 support vector machines with both a quadratic regularizer w

Nonlinear absorption in pyran dyes
Optical Memory and Neural Networks - Tập 18 - Trang 218-222 - 2009
The paper represents the results of nonlinear absorption study for solutions of deciaminomethylenepyran dyes DCM 627 and DCM-684 (yuloidine) at wavelength of 532 nm with 350 ps pulse duration obtained with the use of z-scan technique. It is shown that the induced absorption detected is due to two-photon absorption. Nonlinear and two-photon coefficients of absorption are evaluated. The results of n......
