TCP拥塞控制研究

通过深入研究TCP协议中的拥塞控制机制,研究分析了几种TCP拥塞控制算法TCP Tahoe、TCP Reno及TCP Vegas并提出了今后的一些研究方向。     

利用时延特性的模糊TCP拥塞控制算法

提出了一种基于时延的模糊控制TCP拥塞控制算法(DFCC),采用当前RTT变化和历史变化相结合的方法,通过一个模糊控制器调节CWND,从而对网络拥塞情况有了更好的估计和反应,有效解决了突发拥塞降低吞吐量的问题。仿真试验表明,改进的算法更加准确地监测到网络拥塞,提高了网络的吞吐量。

Walking atomic vegas: ritual,memorial, and toxic landscapes

ABSTRACT

This article proposes the use of ritualized walking to mark and remember invisible threats and the ‘slow violence’ of contaminated landscapes undergoing gradual change. To exemplify the idea, the article describes our proposal for a Plutonium Memorial design, which would be a mnemonic device for marking the location of a proposed nuclear waste storage facility buried under the iconic Las Vegas Strip. Supported with evidence that ritual is commonly used to reinforce collective conscience and memory outside the sacred realm, the core of this memorial design would be regularized and ritualized pilgrimages from one of the most important and symbolic American landscapes, Las Vegas, through the equally prominent Grand Canyon to the less well-known uranium mines in Arizona (the source of nuclear power). Though hyperbolic, the Plutonium Memorial demonstrates how an active cultural-based memorial has potential to preserve narratives around contaminated landscapes. To expand beyond this radical example we schematically speculate on other scenarios that could incorporate more representative (less extreme) haptic rituals around memorials marking slowly unfolding environmental disasters. The intention is to provide new visions for durable memorials built around culture rather than structures, which are engaged with not only the past, but also the future.     

From the Last Frontier to the new Cosmopolitan: A history of casino public relations in Las Vegas

This research examines the use of public relations by the casino gaming industry in Las Vegas, NV. Many are familiar with Las Vegas's extraordinary growth into a tourist destination and cultural icon, but few realize that public relations played a significant part in promoting this growth. Based on archival research, this paper identifies ways in which public relations activities – even when not identified by that particular title – played a role in advancing Las Vegas's casinos into the modern era of corporate ownership and international prominence.
