limit to the tension reinforcement ratio ( ρ) in flexural high strength reinforced concrete (hsrc) members is based on the requirement that tension failure as sufficient rotation capacity are ensured at ultimate limit state. however, the provisions for the total amount of longitudinal reinforcement ratio ( ρ and ρ’) are not associated with any rational derivation. in this paper, a quantitative ...

Timely traffic prediction is important in advanced traffic management systems. Observing traffic flow, we find repetitive or regular behavior over time. By taking advantage of tools in frequency domain analysis, this paper proposes a new criterion function that can detect the onset of congestion. It is found that the changing rate of the cross-correlation between density dynamics and flow rate ...

We propose a model and solution methods, for locating a fixed number of multiple-server, congestible common service centers or congestible public facilities. Locations are chosen so to minimize consumers’ congestion (or queuing) and travel costs, considering that all the demand must be served. Customers choose the facilities to which they travel in order to receive service at minimum travel and...

TCP becomes inefficient and prone to instability when its bandwidth-delay product increases. By sending explicit congestion information from routers to end hosts, both XCP and API-RCP have been proposed to solve the stability issue of TCP in high bandwidth-delay product networks. Since the estimation errors of the network parameters are unavoidable, we would like to design a robust controller t...

Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...

For the congestion problems in high-speed networks, a Metropolis criterion based Q-learning flow controller is proposed. Because of the uncertainties and highly time-varying, it is not easy to accurately obtain the complete information for high-speed networks. The Q-learning algorithm, which is independent of mathematic model, shows the particular superiority in high-speed networks. It obtains ...

In numerous TCP congestion control algorithms, TCP Vegas avoids congestion on its own initiative. However, its slow-start ending quickly and growing unsmoothly cause that the congestin window designing too small and bandwidth utilization declining too rapid, furthermore affect network efficiency and throughput dropping. . . etc. Aimed at the deficiencies, we propose a kind of Logarithmic Slow-S...

Congestion control mechanisms for ATM networks as selected by the ATM Forum tra c management group are described Reasons behind these selections are explained In partic ular selection criterion for selection between rate based and credit based approach and the key points of the debate between these two approaches are presented The approach that was nally selected and several other schemes that ...

In the frame of project «Criteria traffic control quality and effectiveness in Russian Federation» Transportation Laboratory ISTU was invoved into elaboration network performance appraisal. Two alternative congestion measures were considered. The ratio peak period to free flow travel times proposed as a test criterion urban highway reliability.
