Data synchronization with timing

IEEE Transactions on Information Theory, 2001
Summary: This paper proposes and analyzes data synchronization techniques that not only resynchronize after encoded bits are corrupted by insertion, deletion, or substitution errors, but also produce estimates of the time indexes of the decoded data symbols, in order to determine their positions in the original source sequence. The techniques are based

Time-adaptive algorithms for synchronization

Proceedings of the twenty-sixth annual ACM symposium on Theory of computing - STOC '94, 1994
Summary: We consider concurrent systems in which there is an unknown upper bound on memory access time. Such a model is inherently different from the asynchronous model, where no such bound exists, and also from timing-based models, where such a bound exists and is known a priori.

Assuring Resilient Time Synchronization

2008 Symposium on Reliable Distributed Systems, 2008
In many distributed and pervasive systems the clocks of nodes are required to be synchronized to a unique global time. Due to unpredictable system and environment characteristics, the distance of a local clock from global time is a variable factor very hard to predict.

On Time-Synchronized Stability and Control

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2022
Previous research on finite-time control focuses on forcing a system state (vector) to converge within a certain time moment, regardless of how each state element converges. In the present work, we introduce a control problem with unique finite/fixed-time stability considerations, namely time-synchronized stability (TSS), where at the same time, all ...

Timing and Synchronization

1995
The WIS network will consist of digital access and nodal switches interconnected by time division multiplexed and bulk encrypted links. Timing and Synchronization (T & S) functions are therefore of vital importance for WIS. The synchronization concept must define the technical criteria to distribute and maintain permitted timing relationships at the ...

A CMOS synchronous time amplifier

2013 IEEE 10th International Conference on ASIC, 2013
This paper presents a synchronous time amplifier (TA). The proposed TA has predictable amplification process delay and can be synchronous with a clock signal. The TA is implemented and simulated in 0.18 µm CMOS process. It works with 100 Ms/s under 1-V voltage.

Concurrent systems and time synchronization

International Journal of General Systems, 2018
AbstractIn the majority of scientific fields, system dynamics is described assuming existence of unique time for the whole system. However, it is established theoretically, for example, in relativity theory or in the system theory of time, and validated experimentally that there are different times and time scales in a variety of real systems ...

Datalog in Time and Space, Synchronously. [PDF]

, 2013
Motivated by recent developments of Datalog-based languages for highly distributed systems [9], in this paper we introduce a version of Datalog: specifically tailored for distributed programming [2] in synchronous settings, along with its operational and declarative semantics.

Temperature Compensated Time Synchronization

IEEE Embedded Systems Letters, 2009
Time synchronization in embedded sensor networks is an important service for correlating data between nodes and communication scheduling. While many different approaches to the problem are possible, one major effect of clock frequency difference between nodes, environmental temperature changes, has often been left out of the solution.

Revisiting Global Time Synchronization

IEEE GLOBECOM 2007-2007 IEEE Global Telecommunications Conference, 2007
A comparison between global and local time synchronization when applying beacon mechanism of IEEE 802.11 Time Synchronization Function (TSF) to MANETs (Multi-hop ad hoc network) is presented. The evaluation has been carried out with reference to convergence of time while providing robustness towards mobility and stochastic time-delay.
