This paper proposes a channel scheduler in downlink of IEEE 802.16e TDD-OFDMA cellular network which provides users the minimum throughput for best effort traffic. The proposed scheduler is further developed in the consideration of the case that network might become unfeasible, where extra weight functions are introduced into the proportional fair (PF) scheduler so that the proposed extra weigh...

In multi-access wireless communication networks, cochannel interference and timing varying nature of the channel are two important detrimental effects to reduce the network throughput. Adaptive modulation techniques have the potential to substantially increase the spectrum efficiency by providing the users with different levels of throughput according to the channel conditions. In this paper, w...

In this paper, we define a two-parameter family of protocols designed for multihop packet radio networks. We call these protocols rude-CSMA because under certain circumstances, maximum throughput is obtained when nodes, even after sensing a busy channel, transmit packets anyway with a nonzero rate. The performance of these protocols is analyzed for various special and random topologies.

We consider the transmission of a movie over a broadcast network to support several viewers who start watching at arbitrary times, after a wait of at most twait minutes. A recent approach called harmonic broadcasting optimally solves the case of many viewers watching a movie using a constant amount of bandwidth. We consider the more general setting in which a movie is watched by an arbitrary nu...

Over the years a massive amount of high-throughput screening (HTS) data has been collected, however, the data are mainly utilized for providing lead generation programs with chemical entry points. The comparison of molecular structures and HTS data across many projects allows to identify and validate structural patterns of frequent hitters, i.e. compounds which generate multiple hits in various...

Direct regenerations by using mature cotyledonary node as a explants has been shown to be time-saving and convenient strategy for micropropagation of soybean. So we have evaluated regeneration protocol through single shoot using cotyledonary node as a rapid and efficient protocol for two soybean cultivars and one mutant line. Cotyledonary nodes explants obtained from 7-days-old in vitro</em...

Objective(s): Here, a reporter cell line containing two reporter vectors were developed, in order to monitor the Human T-Lymphotropic Virus type1(HTLV-1) infectivity and the cell viability simultaneously. Materials and Methods: The reporter cell line was constructed by stably transfected baby hamster's kidney cell line (BHK-21), with the genomes expressing two different reporters in separate pl...

BACKGROUND Throughput might be partially responsible for sub-optimum organisational and medical outcomes. The present study examined throughput and the challenges to ensuring optimum throughput in hospitals, and determined the effectiveness of a throughput intervention in reducing overcrowding in a public healthcare institution in Trinidad and Tobago. METHODS First, a literature review of thr...
