Enhanced bandwidth of W type plastic optical fibers designed from singly clad step index plastic optical fibers
(Elsevier, 2018-11-02)
We propose a multimode W type (doubly clad) plastic optical fiber which takes the characteristic W-shaped index profile designed from a multimode singly clad step index plastic optical fiber upon modification of the cladding ...

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, 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 ...
