Influence of zero boresight and non-zero boresight pointing error on BER FSO transmission over Malaga atmospheric channel
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2018-03-22)
In this paper, the influence of a zero and a non-zero boresight pointing errors on the performances of free-space optic transmission over the Málaga atmospheric turbulence channel is considered. Closed form expressions for ...
Binary Quantization Analysis of Neural Networks Weights on MNIST Dataset
(Kaunas University of Technology, 2021-08-23)
This paper considers the design of a binary scalar quantizer of Laplacian source and its application in compressed neural networks. The quantizer performance is investigated in a wide dynamic range of data variances, and ...
Analysis of adaptive e‐learning systems with adjustment of Felder‐Silverman model in a Moodle DLS
(Wiley, 2020-05-07)
E‐learning, as a complex system, includes distance learning, teaching materials in various forms and shapes, group and individual learning processes, as well as interactive and tutorial work. To increase the effectiveness ...
Solid-State Synthesis of Silver Nanoparticles and Their Catalytic Application in Methylene Blue Reduction
(Wiley-VCH GmbH, 2020-09-08)
The silver nanoparticles (Ag NPs) were successfully synthesized by a facile solid-state chemical method. Ag NPs were obtained by a mechanochemical reaction between silver nitrate and sodium citrate, with the constant ...
Generating function for the figurative numbers of regular polyhedron
(Hindawi, 2020-04-14)
In this paper, we are going to demonstrate a method for determining the generating functions of tetrahedral, hexahedral, octahedral, dodecahedral, and icosahedral figurative numbers. The method is based on the differences ...
Initial improvement of the hybrid accelerated gradient descent process
(Cambridge University Press, 2018-08-01)
We improve the convergence properties of the iterative scheme for solving unconstrained optimisation problems introduced in Petrovic et al. [‘Hybridization of accelerated gradient descent method’, Numer. Algorithms (2017), ...
Statistical causality and purely discontinuous local martingales
(Taylor and Francis, 2021-07-21)
The statistical concept of causality in continuous time between
filtered probability spaces considered in this paper is based on
Granger’s definition of causality. The given concept of causality can
be connected to the ...
Statistical causality, martingale problems and local uniqueness
(Taylor and Francis, 2018-07-21)
The paper considers a statistical concept of causality in continuous
time in the filtered probability spaces which is based on the Granger’s
definition of causality. The given causality concept is then applied to
the ...
Statistical causality and extremal measures
(2018-10-21)
In this paper we consider the concept of statistical causality
in continuous time between
ows of information, represented by ltra-
tions. Then we relate the given concept of causality to the equivalent
change of measure ...
Statistical causality and measurable separability of σ-algebras
(Science direct, 2021-07-21)
In this paper we consider a concept of statistical causality, based on Granger’s definition
of causality and analyze the relationships between given causality and the concept
of measurable separability of σ-algebras. The ...
