PURPOSE To provide the first detailed information about native language abilities of children who are or had been institutionalized. METHOD The language of ten 30-month-old children raised in Romanian orphanages was compared with that of 30 chronological-age-matched peers: 10 children who had moved recently from orphanages to foster care, 10 children in foster families for at least 1 year, an...

In this paper, an interactive dynamic background scene generating and editing system is proposed based on improved motion graph. By analyzing the input motions with limited frame length and their metadata, our system could synthesize a large amount of various motions to yield a composing dynamic background scene with unlimited frame length by connecting the motion pieces through smooth transiti...

Water shortages are threatening the sustainability of irrigated agriculture in dry environments such as the Southern High Plains (SHP) of the U.S. Corn has been a staple silage crop grown to supply the enormous forage demand associated with dairy and beef feeding industries. The relatively high water use of corn, however, is limiting the extent to which corn can be grown. Although irrigated, co...

We consider power allocation algorithms for fixed-rate transmission over Nakagami-m nonergodic block-fading channels with perfect transmitter and receiver channel state information and discrete input signal constellations, under both shortand long-term power constraints. Optimal power allocation schemes are shown to be direct applications of previous results in the literature. We show that the ...

Indoor spatial navigation is a challenge for individuals with limited visual input (Low Vision) and can be a challenge for individuals with normal visual input in unfamiliar, complex environments. Although outdoor navigation can be achieved using Global Positioning Systems (GPS), these signals are not available for indoor navigation. We have developed an indoor navigation aid that uses a Bayesi...

In many real-world applications of supervised learning, only a limited number of labeled examples are available because the cost of obtaining high-quality examples is high or the prediction task is very specific. Even with a relatively large number of labeled examples, the learning problem may still suffer from limited supervision as the dimensionality of the input space or the complexity of th...

the stolt (f-k) migration algorithm is a direct (i.e. non-recursive) fourier-domain technique based on a change of variables (or equivalently, a mapping) that converts the input spectrum to the output spectrum. the algorithm is simple and efficient but limited to constant velocity. a v(z)(f-k) migration method, capable of very high accuracy for vertical variations of velocity, can be formulated...

A technique is presented for designing command profiles for flexible systems whose operational performance is restricted by a limit on actuator effort. To ensure maximum throughput, the command signal is restricted to a series of positive and negative pulses, whose amplitude is equal to the maximum actuator effort (torque limit). The command profiles are further required to move the system to a...
