Long-term demand for freight and passenger rail traffic in North America is expected to expand increasingly leading to capacity constraints. Both infrastructure investment and operational changes can relieve congestion. However, given the high cost to build and maintain infrastructure, careful consideration of how operational practices can affect or mitigate demand is critical for cost-effectiv...

A comprehensive theory of the modulation response of quantum dot (QD) lasers is developed. The factors limiting the modulation bandwidth are identified and the highest possible bandwidth is calculated. The highest bandwidth increases directly with overlap integral of the electron and hole wave functions in a QD, number of QD-layers, and surface density of QDs in a layer, and is inversely propor...

A candidate Variable Speed Limits Sign (VSLS) control algorithm was applied to an urban freeway in Toronto, Canada using microsimulation. The microsimulation model was combined with a categorical crash model to quantify the impacts of VSLS implementation on safety and traffic performance. The VSLS control strategy was developed as a practical algorithm that responded to real-time measures of tr...

The performance analysis of the two-stage CMOS operational amplifiers employing Miller capacitor in conjunction with the common-gate current buffer is presented. Unlike the previously reported design strategy of the opamp of this type, which results in the opamp with a lower power supply requirements, better phase margin and better speed. The Opamp is designed to exhibit a unity gain frequency ...

a full scale physical model of a thin slab caster with a four-hole design submerged entry nozzle (sen) was constructed. on the basis of the dimensionless reynolds and froude similitude criteria, the fluid flow in a full-scale model is similar to that of the actual system and, hence, the data obtained from the water model can be applied to the actual system. in order to determine the optimum ope...

Active Traffic Management (ATM) applications, such as variable speed limits, queue warning systems, and dynamic ramp metering, have been shown to offer mobility and safety benefits. Yet because they differ from conventional capacity investments in terms of cost, service life, and operating requirements, how to incorporate them into the planning process is not clear. To facilitate such incorpora...

The development of treatment processes from laboratory scale to industries involves a lot of troubles due to the automation of process parameters and fluctuated characteristics of wastewater. In the present study, six different real-time textile effluents of samples such as S1 to S6 are characterized and treated by electrocoagulation process using Stainless Steel (SS) and Aluminum (Al) elec...

In adapting C2 to the 21 century we plan to conduct a controlled Human-InTheLoop (HITL) experiment with new Network Centric Warfare (NCW) technology which will be introduced to sixteen experienced warfighters in the form of a collaborative User Defined Operational Picture (UDOP) with SORTS Force Readiness and intelligence data access enabled by an IP wide area network as a possible improvement ...

Stringent memory access and search speed requirements are two of the main bottlenecks in wire speed processing. Most viable search engines are implemented in content addressable memories (CAMs). CAMs have high operational speed advantage over other memory search algorithms. However, this performance advantage comes with a price of higher silicon area, and higher power consumption. Ternary CAMs ...
