A WEBRC sender transmits packets on a base channel and on T wave channels. The transmission pattern on each wave channel is a sequence of periodically-spaced waves separated by quiescent periods. In a fluid model, the rate of each wave is predominantly described by an exponential decay by a factor of P each TSD seconds. The beginnings of the waves are designed so that the sum over all of the ch...

Long cables, such as are used in cable-stayed bridges, are prone to vibration due to their low inherent damping characteristics. Several studies have investigated the use of an optimal viscous damper attached transversely to dampen such vibration. This paper investigates the potential for improved damping using a semiactive device. The equations of motion of the cable/damper system are reviewed...

Sleep deprivation has been shown to alter decision-making abilities. The majority of research has utilized fairly complex tasks with the goal of emulating 'real-life' scenarios. Here, we use a Lottery Choice Task (LCT) which assesses risk and ambiguity preference for both decisions involving potential gains and those involving potential losses. We hypothesized that one night of sleep deprivatio...

This study examined the effects of two nights of total sleep deprivation (TSD) and two nights of recovery sleep on response inhibition. Thirty-eight young, healthy adults performed a Go-NoGo task at 14 : 00 after: (1) a normal night of sleep; (2) each of two consecutive nights of TSD; and (3) each of two consecutive nights of recovery sleep; they also performed the task at 05 : 00 during the fi...

Recognition tests are a very popular means of assessing the memory effectiveness of advertisements. Unfortunately the recognition scores obtoined by current methods reflect both the memory for an advertisement and the response biases of the respondents. The outhors introduce the theory of signol detection (TSD) v/hich can be used to secure independent estimates of memory and response bias in re...

Coloboma as an ocular finding has been documented in various syndromes. Here we have a case of infantile Tay-Sachs disease associated with unilateral choroidal coloboma. To the best of our knowledge, such an association has not been documented in the literature. Whether such an association is a matter of chance or signifies the involvement of ganglioside metabolism in ocular embryogenesis remai...

He was taken to hospital and did not recover consciousness for five days. XVhen he came to, he noticed that he could not open his left eye. There was no other paralysis but he was told that he had had a temporary left sided hemiplegia for the first three days. He noticed that when he lifted the left upper lid with his hand he saw double, The diagnosis was fracture of base of skull, nasal bones ...

The purpose of this paper is to present the clinical and neuropathological findings in two idiot brothers in whom the mode and time of onset and the pattern of brain anomalies were remarkably similar. Clinically there were similarities with well-known syndromes such as Tay Sachs and Schilder's disease. However, the ultimate diagnosis was to emphasize the frequent difficulties encountered in det...

In late-onset Tay-Sachs disease (LOTS), saccades are interrupted by one or more transient decelerations. Some saccades reaccelerate and continue on before eye velocity reaches zero, even in darkness. Intervals between successive decelerations are not regularly spaced. Peak decelerations of horizontal and vertical components of oblique saccades in LOTS is more synchronous than those in control s...
