A stochastic model for estimation of repair rate for system operating under performance based logistics
(Polish Maintanace Society, 2018-09-01)
Performance Based Logistics (PBL) concept has an aim to improve the system availability and it has been extensively researched in the recent years. These researches showed that inventory level does not impact system ...
Synthesis and spectral characterization of asymmetric azines containing a coumarin moiety: The discovery of new antimicrobial and antioxidant agents
(2018-10-25)
Nine unsymmetrical azines containing a coumarin moiety were prepared by the reaction of the hydrazone of 4-hydroxy-3-acetylcoumarin with differently substituted aromatic aldehydes. The azines were fully spectrally ...
Hybrid modification of accelerated double direction method
(Hindawi, 2018-11-06)
We present a hybridization of the accelerated gradient method with two vector directions. This hybridization is based on the usage of a chosen three-term hybrid model. Derived hybrid accelerated double direction model keeps ...
Statistical causality and local uniqueness for solutions of the martingale problem
(2018-06-15)
In this paper we consider the concept of statistical causality between filtrations associated with
stopping times, which is based on Granger’s definition of causality. Especially, we consider a generalization
of a causality ...
