Several gateway-based congestion control mechanisms have been proposed to support an end-to-end congestion control mechanism of TCP (Transmission Control Protocol). One of promising gateway-based congestion control mechanisms is a RED (Random Early Detection) gateway. Although effectiveness of the RED gateway is fully dependent on a choice of control parameters, it has not been fully investigat...

IN ACCEPTING the honor, and the responsibility, of the George E. Brown Iect-ureship for 1959 I do so, niot for myself, but for a fine group of stimulating colleagues. It is their work and their thinking that will constitute the substanee of this lecture. This :presentation will, therefore, have a personal and restricted focus, a desirable feature in that one area and one viewpoint is examined i...

The prime goal of Vehicular Ad hoc Network (VANET) is to provide life safety on the road. To achieve this, vehicles make use of two types of safety messages one is Periodic safety messages (beacons) to exchange status information e.g. position, speed etc. and second one is Event-driven messages to broadcast in case of an emergency situations e.g. accidents, hardbraking etc. The main objective o...

Objective: The plant lectin concanavalin A (ConA) induced acute hepatitis in mice is a commonly used animal model applied in acute immune-mediated hepatitis studies, but it is not suitable for large animal model of hepatic injury to promote the study of bio-artificial liver support systems in humans and help to assist pre-clinical evaluation. During producing Bama mini-swine model of hepatic in...

The effect on the right atrial pressure and oxygen saturation of expansion of the plasma volume by rapid infusion of 500 ml. 5 per cent glucose has been studied in I4 patients with recent uncomplicated cardiac infarction, and in 5 patients with cardiogenic shock. The findings are contrasted with the effect of intravenousfrusemide (40 mg.) in 8 patients with recent cardiac infarction complicated...

This paper presents congestion management in deregulated power systems. In a deregulated environment, every buyer wants to buy power from the cheapest generator available, irrespective of relative geographical location of buyer and seller. As a consequence of this, the transmission corridors evacuating the power of cheaper generators would get overloaded if all such transactions are approved. C...

AIM The aim of the study was to determine if the tissue Doppler imaging (TDI)-derived myocardial acceleration during isovolumic contraction (IVA) of tricuspid lateral annulus could be used in early detection of RV systolic dysfunction in patients with mitral stenosis (MS), before the clinical signs of systemic venous congestion occur. METHODS One hundred and twelve patients with rheumatic MS ...

This paper proposed a packet drop probability function with an adjustable nonlinearity parameter in random early detection (RED) for active queue management of router to control network congestion. We investigated the effect on average size, throughput, retransmission rate, round-trip time, and fairness index two widely used loss-based congestion algorithms: Reno CUBIC. Simulations were perform...
