This paper studies the startup dynamics of TCP on both high as well as low bandwidth-delay network paths and proposes a set of enhancements that improve both the latency as well as throughput of relatively short TCP transfers. Numerous studies have shown that the timer and congestion control mechanisms in TCP can have a limiting eeect on performance in the startup phase. Based on the results of...

The emergence of real-time applications, like Voice over IP and video conferencing, in IP networks implies a challenge to the underlying infrastructure. Several real-time applications have requirements on timeliness as well as on reliability and are accompanied by signaling applications to set up, tear down and control the media sessions. Since neither of the traditional transport protocols res...

When startup innovation involves a potentially disruptive technology – initially lagging in the predominant performance metric, but with a potentially favorable trajectory of improvement – incumbents may be wary of engaging in cooperative commercialization with the startup. While the prevailing theory of disruptive innovation suggests that this will lead to (exclusively) competitive commerciali...

This paper is one of a series of papers evaluating the performance of plasmatron methane reformers. An accompanying paper describes the steady state performance of a plasmaassisted reformer operating with methane under partial oxidation conditions. In this paper, the startup performance of plasmatron methane reformers is described.

The Transmission Control Protocol (TCP) uses the SlowStart mechanism at the beginning of a connection and after idle times. The Slow-Start delays the transport of data in particular if the round-trip time is large, which is undesirable for interactive applications. In order to speed up transfers, several alternatives have been proposed recently. This paper evaluates the performance and robustne...

A new method has been developed for the detection of broken rotor bars fault in squirrel cage induction motor during startup regimes. The incipient detection of fault is made by using DWT analysis of FIR low pass filtered original startup transient current signal. The extracted particular characteristic evolution of the time-varying signal is used as a fault index. The method was tested using h...

In this paper, we describe two techniques for assuring a high integrity startup in a PC based computing environment. We begin with background information on PC startup procedures and current integrity threats against normal PC startup. We then describe a sound technique for assuring a high integrity startup and the basis for its soundness. Next we show a second method which is not sound, but wh...

We study the impact of incentive pay, local development objectives and government constraints on university licensing performance. We develop and test a simple contracting model of technology licensing offices, using new survey information together with panel data on U.S. universities for 1995-99. We find that private universities are much more likely to adopt incentive pay than public ones, bu...

Due to their higher efficiency of energy utilisation heat-integrated column systems have been widely used in chemical industry. However, the heat-integration leads to difficulties in startup of such columns, i.e. a long startup time and thus considerable costs will be resulted. In this work, a study consisting of modelling, simulation, optimisation and experimental verification is made for deve...
