MAXIMUM RELIABILITY K-CENTER LOCATION PROBLEM
(Union of Mathematicians of Macedonia - ARMAGANKA, 2020-10-31)
This paper presents an approach for solving the maximum reliability k-center location problem. We are modifying the well-known p-center problem in order to determine the location of the observed objects and maximize the ...
KORELACIJA IZMEĐU NAČINA AKTIVIRANJA MONTMORILONITA K10 I SADRŽAJA FORMALDEHIDA U UREA-FORMALDEHIDNIM KOMPOZITIMA
(Faculty of Management Herceg Novi, 2022-05-26)
U ovom radu je izvršeno poređenje načina aktiviranja montmorilonita (MMT) K10 sa sadržajem formaldehida (FA) u urea-formaldehidnim (UF) kompozitima. Uzorci MMT-a K10 su aktivirani na dva načina: termički i pomoću sumporne ...
The influence of the modification of the montmorillonite KSF and K10 on the hydrolytic stability of UF composites
(2021-09-24)
In this work, the hydrolytic stability of composites based on the urea-formaldehyde resin (UF) and montmorillonite-MMT (K1 0 and KSF) as a formaldehyde (FA) scavenger was investigated. K10 and KSF were activated by sodium ...
Effect of silica on the properties of elastomeric materials based on NR/BR/SBR ternary rubber blend
(University in Banjaluka, Faculty of Technology, 2018-11-02)
The effects of pyrogeneous silica on the mechanical properties of elastomeric materials based on natural rubber (NR), polybutadiene rubber (PB) and styrene-butadiene rubber (SBR) are reported. For sample preparations the ...
