A multi-center surveillance study was conducted in Thailand during 1999-2000 to determine antimicrobial susceptibilities among the respiratory pathogens Streptococcus pneumoniae (n = 206), Haemophilus influenzae (n = 305), and Moraxella catarrhalis (

The means of measurement of adenosine and deoxyadenosine in urine was developed by separating adenosine and deoxyadenosine from other compounds using high-performance liquid chromatography with column switchings. This method is simple and convenient

We develop an analytic model to evaluate non-saturation energy consumption of IEEE 802.11 DCF, based on the model in G.R. Cantieni et al., (2005). The model explicitly takes into account both the carrier sensing mechanism and an additional backoff in

Most analytical models proposed so far for IEEE 802.11 distributed coordination function (DCF) focus on saturation performance. In this paper, we develop an analytic model for unsaturation throughput evaluation of IEEE 802.11 DCF, based on Bianchi's

We propose a new backoff algorithm which incorporates release delay in addition to backoff delay. In the proposed algorithm the backoff counter of a successful user is gradually decreased. The rate of the decrement is controlled by the release delay.

E nergy efficiency is an important issue for a mobile communication terminal which operates by a battery. Most of analytical models proposed so far for IEEE 802.11 distributed coordination function (DCF) focus on saturation performance. In this paper

We propose a new backoff algorithm, which incorporates release delay in addition to backoff delay. In the proposed algorithm the backoff counter of a successful user is gradually decreased until the generation of the next packet, while it is immediat

We propose a congestion control scheme for interconnected networks where several local area networks (LANs) are connected to a high speed backbone network via gateways. In such a network, traffic congestion may occur due to the difference of transmis
