High-Speed Optical Interconnections for Digital Systems

II As an alternative to electrical interconnections, optical interconnections are being investigated for digital systems that require high speed, density, and connectivity. In particular, diode-laser-based optical interconnections with high optoelectronic conversion efficiencies promise simple interconnections that can operate even at gigahertz. rates. Optical modules in which critical alignmen...

A balanced rail-to-rail all digital comparator using only standard cells

An all-digital comparator with full input range is presented. It outperforms the nowaday all-digital comparators with its large rail-torail input range. This is achieved by the proposed “Yin-yang” balance mechanism between the two logic gates: NAND3 and OAI (Or-AndInvert). The important design considerations to achieve this balance are presented, such as the driving strength manipulation and th...

Dispatch coordination between high-speed and conventional rail systems

Cross-line trains, as a link between high-speed and conventional rail networks, will increase the complexity of transport organization and lead to significant challenges in dispatch coordination between the two systems. Based on the characteristics of high-speed transport organization, this paper deals with the necessity of dispatch coordination between high-speed and conventional lines from th...

Megacities and High Speed Rail systems : which comes first ?

A megacity is usually defined as a metropolitan area with a total population in excess of 10 million people. The number of megacities is increasing worldwide: in 1950 they were 4; in 1980 they were 28, in 2002 they were 39 and by 2015 they will be 59. In most agglomerations and megacities, urban planning and public infrastructure can guide the urban development in order to achieve a proper sust...
