Tribological Performance of 60NiTi Alloy Under Varying Contact Conditions and Elevated Temperatures in Linear Reciprocating Sliding

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the tribological response of 60NiTi alloy under dry, water‐lubricated and high‐temperature conditions. The alloy exhibits decreasing wear volume and friction with increasing temperature due to the formation of protective oxide layers. The work clarifies dominant wear mechanisms and demonstrates the suitability of 60NiTi for high‐

Iterative timing recovery

IEEE Signal Processing Magazine, 2004
The last decade has seen the development of iteratively decodable error-control codes of unprecedented power, whose large coding gains enable reliable communication at very low signal-to-noise ratio (SNR). A by-product of this trend is that timing recovery must be performed at an SNR lower than ever before.

Timing recovery for UWB signals

IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005
The paper is concerned with timing recovery for ultra-wideband communications operating in a dense multipath environment. A timing algorithm is proposed that exploits the samples of the received signal to estimate the start of the individual frames with respect to a local reference (frame timing) and the location of the first frame in each symbol ...

Tracheostomy Timing Affects Stroke Recovery

Journal of Stroke and Cerebrovascular Diseases, 2014
The timing of tracheostomy in stroke patients unable to protect their airway has become a topic of debate. Proponents for early tracheostomy (ET) cite benefits including less ventilation-associated pneumonia, less sedative drug use, shorter length of stay, and reduced mortality in comparison with late tracheostomy (LT).We examined the timing of ...

Unveiling the recovery time zone of tolerance: when time matters in service recovery

Journal of the Academy of Marketing Science, 2017
This article examines the link between recovery time and customer compensation expectations for service failures that cannot be immediately redressed. First, we show that the relationship between recovery time and compensation expectations is nonlinear. Initially, in a recovery time zone of tolerance, compensation expectations do not increase.
