Influence of Sliding Time Window Size Selection Based on Heart Rate Variability Signal Analysis on Intelligent Monitoring of Noxious Stimulation under Anesthesia

open access: yesNeural Plasticity, 2021
In recent decades, little progress of objective evaluation of pain and noxious stimulation has been achieved under anesthesia. Some researches based on medical signals have failed to provide a general understanding of this problem.

Process window acquisition for impact welding processes

open access: yesMaterials & Design, 2017
Abstract Joining processes by high speed impacts such as explosion welding and electromagnetic pulse welding offer great advantages compared to conventional joining methods, especially fusion welding. However, a comprehensive understanding of the mechanisms and phenomena does not exist yet and thus process design largely involves empirical data.

Asymptotic Approximations for TCP Compound

open access: yes, 2016
In this paper, we derive an approximation for throughput of TCP Compound connections under random losses. Throughput expressions for TCP Compound under a deterministic loss model exist in the literature.

Cutoff for the East process [PDF]

open access: yes, 2014
The East process is a 1D kinetically constrained interacting particle system, introduced in the physics literature in the early 90's to model liquid-glass transitions. Spectral gap estimates of Aldous and Diaconis in 2002 imply that its mixing time on $L$

A window into learning: case studies of online group communication and collaboration [PDF]

open access: yes, 2006
The two case studies presented explore the potential offered by in‐depth qualitative analysis of students’ online discussion to enhance our understanding of how students learn. Both cases are used to illustrate how the monitoring and moderation of online

Ruin probabilities with dependence on the number of claims within a fixed time window [PDF]

open access: yes, 2016
We analyse the ruin probabilities for a renewal insurance risk process with inter-arrival time distributions depending on the claims that arrived within a fixed (past) time window. This dependence could be explained through a regenerative structure.
