Optimal Rendezvous Guidance Using Linear Quadratic Control

MATEC Web of Conferences, 2016
This paper handles with an energy optimal guidance law for rendezvous mission, based on linear quadratic control (LQC) problem. Rendezvous of two satellites are expressed by a nonlinear relative orbit dynamic model.

Discrete time McKean-Vlasov control problem: a dynamic programming approach [PDF]

, 2015
We consider the stochastic optimal control problem of nonlinear mean-field systems in discrete time. We reformulate the problem into a deterministic control problem with marginal distribution as controlled state variable, and prove that dynamic ...

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

Advanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Delayed Stochastic Linear-Quadratic Control Problem and Related Applications

Journal of Applied Mathematics, 2012
We discuss a quadratic criterion optimal control problem for stochastic linear system with delay in both state and control variables. This problem will lead to a kind of generalized forward-backward stochastic differential equations (FBSDEs) with Itô’s ...

Scheduling and Power Control for V2V Broadcast Communications With Co-Channel and Adjacent Channel Interference

IEEE Access, 2019
This paper investigates how to mitigate the impact of both the co-channel interference and the adjacent channel interference (ACI) in the vehicle-to-vehicle (V2V) broadcast communication by scheduling and power control.

Schooling Trajectories and the Development of Brain Dynamics: A Comparative Study of Montessori and Traditional Education

Advanced Science, EarlyView.
We investigate whether Montessori and traditional schooling systems shape the developmental trajectory of large‐scale brain dynamics in different ways. We quantify the arrow of time (“non‐reversibility”) in neural activity during resting state and movie‐watching, revealing distinct maturational patterns.

Ultra‐Wide‐Field Noninvasive Imaging Through Scattering Media Via Physics‐Guided Deep Learning

Advanced Science, EarlyView.
We propose a physics‐guided adaptive dual‐domain learning method for ultra‐wide‐field noninvasive imaging through scattering media, namely UNI‐Net. Our method not only reduces the requirement for real experimental data by an order of magnitude but also enables clear imaging of complex scenes with an ultra‐large field of view, which is 164 times the OME

Evaluation of linearly solvable Markov decision process with dynamic model learning in a mobile robot navigation task

Frontiers in Neurorobotics, 2013
Linearly solvable Markov Decision Process (LMDP) is a class of optimal control problem in whichthe Bellman’s equation can be converted into a linear equation by an exponential transformation ofthe state value function (Todorov, 2009).

A kind of non-zero sum mixed differential game of backward stochastic differential equation

Advances in Difference Equations, 2020
This paper is concerned with a non-zero sum mixed differential game problem described by a backward stochastic differential equation. Here the term “mixed” means that this game problem contains a deterministic control v1 $v_{1}$ of Player 1 and a random ...
