Enhancing the Properties of PA6 and PA6/Ionomer Scraps Blend With CaCO3 Nanoparticles: Rheological, Mechanical, Thermal, and Morphological Evaluation

open access: yesPolymer Engineering &Science, EarlyView.
ABSTRACT This study investigated the effects of incorporating ionomer scraps and CaCO3 nanoparticles on the rheological, mechanical, thermal, and morphological properties of neat polyamide 6 (PA6) and a PA6/ionomer scraps (80/20) blend. The ionomer formed an immiscible dispersed phase within the PA6, acting as an impact modifier; however, it reduced ...

Performance improvement of carbon fiber‐reinforced ABS composites by introducing fullerene nanoparticles

open access: yesPolymer International, EarlyView.
Fullerene particles were incorporated with CF‐reinforced acrylonitrile–butadiene–styrene terpolymer (ABS) matrix at three different compositions by a melt‐compounding process. These insights are crucial for the optimization of conductive hybrid composites for various applications.

Improvement of water absorption behavior and mechanical properties of woven jute fiber‐reinforced epoxy composites with waste eggshell filler

open access: yesPolymer International, EarlyView.
This study investigates the influence of waste eggshell powder on the water absorption and mechanical properties of jute fiber‐reinforced epoxy composites. Optimal eggshell filler content (2 wt%) significantly enhances composite performance by reducing water absorption and improving mechanical properties.

Negative Stiffness Induced and Controlled by Constriction

open access: yesphysica status solidi (b), EarlyView.
Structures with negative stiffness can be stabilized by constriction of external displacement. Furthermore, constriction can make a conventional positive stiffness material exhibit negative stiffness, either bidirectional or unidirectional (shown in the figure).

Adaptive Sliding Mode Control Design for Interval Type‐2 T–S Fuzzy Systems With Time Delay: An Event‐Triggered Approach

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In this work, a new event‐triggered adaptive first‐order sliding mode control method is proposed for nonlinear systems with constant time delays, modeled by interval type‐2 Takagi–Sugeno (T–S) fuzzy systems. To handle matched disturbances with unknown upper bounds, a non‐overestimating adaptation strategy for the control coefficient is ...

Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...

Zdravstveni privatizacijski pendulum

open access: yesDruštvena istraživanja : časopis za opća društvena pitanja, 1999
The European model of competitiveness in health protection implies private initiative and private ownership on all levels of the health system, but under the condition of achieving a balance among the elements of equity, efficiency and accessibility of the health protection system. The balancing of these three principles presents a safe barrier against
