Realistic modelling and interactive rendering of forestry and landscape is a challenge in computer graphics and virtual reality. Recent new developments in plant growth modelling and simulation lead to plant models faithful to botanical structure and development, not only representing the complex architecture of a real plant but also its functioning in interaction with its environment. Complex ...

TODD A. DELONG BARRY W. JOHNSON Universiiy of Virginia JOSEPH A. PROFETA 111 Union Switch and Signal, Inc. AS EARLY AS THE 1960~, designers recognized the importance of incorporating fault tolerance into microelectronic designs. However, they often performed this task late in the process when the design was near completion. As computer systems become more complex, designers must consider fault ...

This paper proposes a new double-edge-triggered implicitly level-converting flip-flop, suitable for a low-power and low-voltage design. The design employs a sense amplifier architecture to reduce the delay and power consumption. Experimentally, when implemented with a 130-nm, single-Vt and 0.84 V VDD process, it achieves 64% power-delay product (PDP) improvement, and moreover, 78% PDP improveme...
