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
