Quantitative and Algorithmic aspects of Barrier Synchronization in Concurrency [PDF]

Discrete Mathematics & Theoretical Computer Science, 2021
In this paper we address the problem of understanding Concurrency Theory from a combinatorial point of view. We are interested in quantitative results and algorithmic tools to refine our understanding of the classical combinatorial explosion phenomenon ...

Deep Robust Moving Horizon Estimation for Nonlinear Multi-Rate Systems [PDF]

Sensors
In this paper, a moving horizon estimation (MHE)-based state estimation problem is studied for asynchronous multi-rate nonlinear systems. First, the asynchronous multi-rate system is transformed into a synchronous system at measurement sampling points ...

The Combinatorics of Barrier Synchronization [PDF]

Lecture Notes in Computer Science, 2019
In this paper we study the notion of synchronization from the point of view of combinatorics. As a first step, we address the quantitative problem of counting the number of executions of simple processes interacting with synchronization barriers. We elaborate a systematic decomposition of processes that produces a symbolic integral formula to solve the

Gut jet lag: how circadian rhythm disruption undermines the Chrono-Microbiota-Motility axis and induces functional constipation [PDF]

Frontiers in Nutrition
Functional constipation (FC) is a highly prevalent gastrointestinal disorder globally. Its complex and multidimensional pathophysiological mechanisms and the limitations of conventional treatments highlight the urgent need to explore new theoretical ...

Barrier synchronization on wormhole-routed networks [PDF]

IEEE Transactions on Parallel and Distributed Systems, 2001
In this paper, we propose an efficient barrier synchronization scheme on networks with arbitrary topologies. We first present a distributed method in building a barrier routing tree. The barrier messages can be delivered adaptively according to the hierarchy of the established barrier tree to void congestion and faulty nodes in the network.

WAWA: Wavelet Analysis-Based Watermarking Authentication for GNSS Civil Signal with Immediate Symbol-Level Verification [PDF]

Sensors
Existing GNSS authentication schemes suffer from critical drawbacks such as high verification latency and prohibitive memory requirements, leaving time-sensitive applications vulnerable to spoofing. The core challenge is the inability to transmit strong,

diffReplication - An Energy-Aware Fault Tolerance Model for Silent Error Detection and Mitigation in Heterogeneous Extreme-scale Computing Environment [PDF]

Journal of Universal Computer Science, 2023
At extreme scale, the frequency of silent errors – a class of errors that remain undetected by low-level error detection mechanisms – increases significantly with the computational complexity of the application and the scale of the ...

Nonsingular Terminal Sliding Mode Control Based on Adaptive Barrier Function for n^th-Order Perturbed Nonlinear Systems

Mathematics, 2021
In this study, an adaptive nonsingular finite time control technique based on a barrier function terminal sliding mode controller is proposed for the robust stability of nth-order nonlinear dynamic systems with external disturbances. The barrier function
