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 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 ... -
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 ... -
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 and separable processes
(Science Direct, 2020-11-21)In this paper we consider the statistical concept for continuous-time stochastic processes, which is based on Granger’s definition of causality. We, also, show that separability is directly related to causality concepts. ... -
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 ... -
Statistics of simultaneous Rice, Nakagami-m and α−μ fadings after SC combining
(2020 19th International Symposium INFOTEH-JAHORINA (INFOTEH), 2020-04-16)This paper presents initial results of a research towards statistical description of diversity-combined wireless signals that propagate over different environments. This kind of situation is encountered when receiver has ... -
A Stochastic Model for Achieving Required Level of Availability Based on the Repair Rate Analysis
(Strojarski fakultet u Slavonskom Brodu; Fakultet elektrotehnike, računarstva i informacijskih tehnologija Osijek; Građevinski i arhitektonski fakultet Osijek, 2019-07-25)The aim of this paper is to set framework for the repair rate in order to achieve required availability of a repairable system with alternating renewal process where the failure rate is Weibull distributed. In order to ... -
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 ... -
STRUKTURIRANJE EKOLOSKI PRIHVATLJIVIH ELASTOMERNIH KOMPOZITNIH MATERIJALA
(Univerzitet u Kragujevcu, Agronomski fakultet u Čačku, 2018-03-09)Kod recikliranja otpadne gume neophodno je poznavati hemijski sastav otpadnog proizvoda, ukoliko će se on koristiti u recepturama za nove hibridne elastomerne materijale. Kompozitni elastomerni materijali dobijeni od ... -
Strukturiranje elastomernih materijala za primenu u poljoprivredi
(UNIVERZITET U KRAGUJEVCU, AGRONOMSKI FAKULTET U ČAČKU, 2019-03-15)Poljoprivreda i poljoprivredna industrija zahtevaju elastomeme proizvode koji mogu izdržati dugotrajnu izloženost ekstremnim naponima i hemikalijama. Elastomeri dobijeni od etilen-propilen-dienskog kaučuka (EPDM) nalaze ... -
A study of pv system application on the sustainable development in Serbia, XIV Conference of Chemists
(University in Banjaluka, Faculty of Technology, 2022-10-22)Climate change is one of the most significant environmental problems and is affecting the entire global population. Renewable sources of energy (RES) are vital to deal with this problem. Solar energy, especially ... -
Suzuki type fixed point results and applications in partially ordered Sb -metric spaces
(University of Novi Sad, Faculty of Sciences, Department for Mathematics and Informatics, 2019-01-12)In this paper we give some applications to integral equations as well as homotopy theory via Suzuki type fixed point theorems in partially ordered complete Sb - metric space by using generalized contractive conditions. We ... -
