Genetic algorithms require relatively large computation time to solve optimization problems, especially in VLSI CAD such as module placement. Therefore, island-based parallel GAs are used to speed up this procedure. The migration schemes that most researchers proposed in the past have migration near or after the demes converged [1,2]. However, for the placement of medium or large standard-cell ...

In the 2014 year’s campaign of Experimental Advanced Superconducting Tokamak (EAST), a series of Magnetohydrodynamics (MHD) instabilities were observed as the launching of Neutral Beam Injection (NBI), the most interesting one of which is the neoclassical tearing mode (NTM). Evidence clearly shows that a kink mode present after a strong sawtooth-like (ST-like) crash leaves a perturbation near t...

X k=1 z 0k A0;k(z M)Mi01(z M): (41) This formula makes transparent exactly what happens in a recursive computation of the correlation functions. At every stage i, we have the Z-transform at points M 0i n of the appropriate function. In going to the (i + 1)st stage, the rst term Mi01(z M) ensures that values at the previous stage are retained at the even points, while the second term interpolate...

During submonolayer homoepitaxy, instability in the shapes of growing two-dimensional islands can develop due to the diffusion-limited aggregation of deposited adatoms at their edges. However, in metal (100) systems, periphery diffusion is typically efficient, quenching this shape instability, and resulting in simple near-square or near-rectangular shapes of isolated islands. Despite this featu...

purpose: to compare fusional vergence amplitudes in patients with symptomatic and asymptomatic near exophoria methods: this cross-sectional study included 102 patients with near exophoria and asthenopia and 86 with asymptomatic near exophoria, all of whom were aged 15-35 years and had best corrected far visual acuity better than 20/25. far and near fusional vergence amplitudes were evaluated in...

The study addresses the distribution and diversity of mesozooplankton near the active volcano-Barren Island (Andaman Sea) in the context of persistent volcanic signature and warm air pool existing for the last few months. Sampling was done from the stations along the west and east side of the volcano up to a depth of 1,000 m during the inter monsoon (April) of 2006. Existence of feeble warm air...

Abstract A linear numerical model of an island or a tall seamount is used to explore superinertial leaky resonances forced by ambient vertically and horizontally uniform current fluctuations. The assumes circularly symmetric topography (including shallow reef) allows realistic stratification bottom friction. As long as there substantial stratification, number are found, when the island’s flanks...

The Pacific Islands, also known as Oceania, have been subdivided traditionally by anthropologists into three main geographic regions: Melanesia, Micronesia, and Polynesia (Fig. 1). Following Green (1991), prehistorians now stress the division between Near Oceania in the west (including the Bismarck Archipelago and the Solomon Islands), and Remote Oceania (which includes all of island Melanesia ...

The vertical distribution and swimming ability of the three larval stages (Zoea I, II, and III) of Homarus gammarus were determined in laboratory experiments. In an artificial water column, newly hatched larvae were positively phototactic to white light at intensities near 0.6 mmol m 2 s . The positive phototactic behaviour decreased with increasing larval age and stage. Accordingly, older larv...
