Multibody Modeling and Nonlinear Control of a Pantograph Scissor Lift Mechanism [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2023
In this paper, a new strategy for developing effective control policies suitable for guiding the motion of articulated mechanical systems that are described within the framework of multibody system dynamics is proposed.

Behaviour equivalent max-plus automata for timed petri nets under open-loop race-policy semantics [PDF]

open access: yesDiscrete Event Dynamic Systems, 2021
AbstractTimed Petri nets and max-plus automata are well known modelling frameworks for timed discrete-event systems. In this paper we present an iterative procedure that constructs a max-plus automaton from a timed Petri net while retaining the timed behaviour.

Using Epidemic Modeling, Machine Learning and Control Feedback Strategy for Policy Management of COVID-19

open access: yesIEEE Access, 2022
Coronavirus disease (COVID-19) is one of the world’s most challenging pandemics, affecting people around the world to a great extent. Previous studies investigating the COVID-19 pandemic forecast have either lacked generalization and scalability ...

“Inspiring” Policy Transfer: Analysis of Urban Renewal in Four First-Tier Chinese Cities

open access: yesLand, 2022
Most Chinese cities have spent decades achieving urbanisation. So far, rural urbanisation has shifted to urban renewal. However, the distinction between a rapidly changing social environment and the establishment of an institution has led to the failure ...

Optimal Open-Loop Routing and Threshold-Based Allocation in TWO Parallel QUEUEING Systems with Heterogeneous Servers

open access: yesMathematics, 2021
In this paper, we study the problem of optimal routing for the pair of two-server heterogeneous queues operating in parallel and subsequent optimal allocation of customers between the servers in each queue.

Equilibrium investment and risk control for an insurer with non-Markovian regime-switching and no-shorting constraints

open access: yesAIMS Mathematics, 2020
In this paper, we study the time-consistent equilibrium investment and risk control policies for an insurer under the mean-variance criterion. The dynamics of liability and assets are given by non-Markovian regime-switching models driven by a Brownian ...

Some Results on the Control of Polluting Firms According to Dynamic Nash and Stackelberg Patterns

open access: yesEconomies, 2021
In this paper we model the conflict between the group of polluting firms in a country and any social planner in the same country who attempts to control the volume of emissions generated during the production process.
