Asynchronous Delayed Optimization With Time-Varying Minibatches
IEEE Journal on Selected Areas in Information Theory, 2021Large-scale learning and optimization problems are often solved in parallel. In a master-worker distributed setup, worker nodes are most often assigned fixed-sized minibatches of data points to process. However, workers may take different amounts of time to complete their per-batch calculations.

Optimal estimation of time-varying delay
ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003The authors report on time-varying delay estimation in a multisource single direct acoustic path environment. The signals are stochastic nonstationary processes. The time delays are deterministic time-varying functions described by a finite dimensional vector theta of unknown parameters. The observation noise is spatially correlated.

On time‐varying cyclic delay diversity
European Transactions on Telecommunications, 2006AbstractCyclic delay diversity (CDD) was introduced in 2001 to obtain spatial diversity in an orthogonal frequency division multiplexing (OFDM) based transmission system. In contrast to space‐time codes, CDD introduces no additional effort at the receiver side, since CDD changes only the channel impulse response seen by the receiver by increasing the ...

Teleoperation of Mobile Robots With Time-Varying Delay
IEEE Transactions on Robotics, 2006This paper proposes a stable control structure for the bilateral teleoperation of mobile robots. The proposed control structure includes a time-delay compensation placed on both the local and remote sites of the teleoperation system. To illustrate the performance and stability of the proposed control structure, experiences on a Pioneer 2DX mobile robot

Averaging Theory for Delay Difference Equations with Time-Varying Delays
SIAM Journal on Applied Mathematics, 1999A theory of averaging on both finite and infinite time intervals is developed for delay difference equations with time-varying delays. The main results are applied to the adaptive identification of a pipe mixing problem in the presence of time-varying transport delays.

AbstractThis paper investigates the synchronization problem of a class of complex dynamical networks via an adaptive control method. It differs from existing works in considering intrinsic delay and multiple different time‐varying coupling delays, and uncertain couplings.

On stability properties of time-varying systems with delays
IEEE Conference on Decision and Control and European Control Conference, 2011We consider several stability properties in the framework of input-to-state stability for time-varying systems with delays. By following a natural approach to convert a time-varying system to an auxiliary time-invariant system, we obtain several results including Razumikhin-type stability criteria, Razumikhin-Lyapunov functions with non-strict decay ...

The passivity of neural networks with time-varying delay
2019 IEEE Symposium Series on Computational Intelligence (SSCI), 2019This study addresses the passivity analysis of neural networks with time-varying delay. By constructing an improved Lyapunov-Krasovskii functional (LKF) and utilizing some newly integral inequalities, a further sufficient condition for the passivity of the considered system is obtained.

Stabilization of linear systems with time‐varying delays
International Journal of Robust and Nonlinear Control, 2012SUMMARYThis paper is concerned with the stability and stabilization problems for a class of time‐delayed systems, whose time‐varying delays are studied via Markovian approach. By separating the delay interval into several subintervals and by considering the inherent distribution of time‐varying delay, a new model is firstly developed.

Before we complete Part I of the book, on predictor feedback for linear systems, and before we move on to delay-adaptive control in Part II, we examine a somewhat related problem of linear (time-invariant) systems with time-varying input or output delays.
