A GROUPOID FRAMEWORK FOR STUDY ASYMPTOTIC BEHAVIOR OF A DISCRETE SYSTEM [PDF]
Fiabilitate şi Durabilitate, 2017 The purpose of this note is to introduce four different groupoids associated to a function f:XNNX, where X is a uniform space. Thesegroupoids allow to study within a unified framework theasymptotic behavior of thediscrete systems of the form xn+1 =

Friction compensation of servo system based on terminal switching function
The Journal of Engineering, 2013 Based on the LuGre friction model, a sliding mode adaptive controller is presented to compensate for the friction in the servo system. The terminal switching function is selected as the sliding mode surface, which can make the error of the system ...

Multi-Scroll Attractor and Multi-Stable Dynamics of a Three-Dimensional Jerk System
Energies, 2023 A multi-scroll attractor reflects the structural diversity of the dynamic system, and multi-stability behavior reflects its state diversity. Multi-scroll and multi-stability chaotic systems can produce complex random sequences, which have important ...

Realization of the Triple Points of Equilibrium Hydrogen and Equilibrium Deuterium
Transactions of the Society of Instrument and Control Engineers, 2002 The triple points of equilibrium hydrogen and equilibrium deuterium have been realized using a calorimetric method and sealed cells, which include hydrogen (or deuterium) and a catalyst for the ortho-para equilibration. Anomalous increases on heat capacity curves of each substance, which markedly disturb melting curves of the triple point, are observed

Rumor Spreading Model Considering Individual Activity and Refutation Mechanism Simultaneously
IEEE Access, 2020 With the rapid development of social networks, an increasing number of factors will affect the spread of rumors. In this paper, we simultaneously consider individual activity differences and rumor-refuting nodes, and we propose a new multifactor model ...
