2023年6月14日 · EDCF（Enhanced Distributed Coordination Function，增强型分布式协调函数）是一种用于无线局域网（WLAN）中的媒体访问控制（MAC）协议，它是基于IEEE 802.11标准的分布式协调函数（DCF）的改进版本。

2004年9月8日 · In this paper, we evaluate the performance of EDCF by dividing the traffic into two groups, namely real-time packets and non-real-time packets, and use an analytical model to quantify the performance of both IFS priority and contention window (CW) priority in the EDCF.

2007年2月26日 · In this paper, we propose a modified EDCF scheme, M-EDCF, to improve the Quality of Service (QoS) of the IEEE 802.11e wireless network. The IEEE 802.11e standard is presented to support QoS at medium access control level using a priority scheme by differentiating the inter-frame space and the initial window size.

Endothelium-derived relaxing factor (EDRF) and endothelium-derived contracting factor (EDCF) are released by endothelial cells following stimulation by a wide range of chemical agonists acting on specific endothelial membrane receptors and by …

The essential role of the endothelium in vascular homeostasis is associated with the release of endothelium-dependent relaxing and contractile factors (EDRF and EDCF, respectively). Different from arteries, where these factors are widely studied, the vasoactive factors derived from the venous endoth …

Schematic diagram shows endothelium-derived contracting factors (EDCF) produced in the blood vessel wall Cyclooxygenase pathway after stimulation by receptors (open circles) or physical forces can form thromboxane A2 (TXA^, prostaglandin H2 (PGH^, or superoxide radical (O2~), which inactivate (©) nitric oxide (NO).

2021年8月25日 · For the TFCV block, it vectorizes the tensor with time-frequency attributes for improving the prediction accuracy. In the experimental phase, we investigate the effectiveness of our network via ablation experiments on AVEC2013 and AVEC2014 depression databases.

The 802.11 standard distinguishes two main methods of operation with respect to channel access, the Distributed Coordination Function (DCF) and the Enhanced Distributed Channel Access (EDCA), where the latter is the mandated method to be used in vehicular networks (in 802.11p).
