HPF has been designed to provide portable performance on distributed memory machines. An important aspect of portable performance is the behavior of the available HPF compilers. Ideally, a programmer may expect comparable performance between different HPF compilers, given the same program and the same machine. To test the performance portability between compilers, we have designed a special ben...

In a strabismus clinic, measurement of distance stereopsis is particularly useful in the management of intermittent exotropia and esotropia of divergence paralysis type. This is mainly because reduction in the distance stereopsis is a sensitive sign of early deterioration of these strabismic disorders and generally makes a case for the surgical intervention [10]. Various tests have been used fo...

EMISSION MODEL: ENVIVER Nowadays, the environmental aspects from air pollution caused by traffic are becoming more and more relevant. TNO has developed some detailed emission models for vehicles (VERSIT+) in order to be able to predict emissions from road traffic. A specific piece of software, EnViVer, has been developed to link traffic simulation software (VISSIM) to emission models, such that...

Millisecond dips in the RXTE/PCA light curve of Sco X-1 were reported recently (Chang et al. 2006), which were interpreted as the occultation of X-rays from Sco X-1 caused by Trans-Neptunian Objects (TNO) of hundred-meter size. Inconclusive signatures of possible instrumental effects in many of these dip events related to highenergy cosmic rays were later found (Jones et al. 2006) and the TNO i...

In order for a defense organization to gain understanding of their performance in complex tactical situations it is important to accurately model the way opposing and own forces operate. It is a significant challenge to develop such models due to the increasing interdependence between personnel and technology. To gain a clear insight in how personnel and technology (or a man-machine network) to...

By telescopic tracking, we have established that the transneptunian object (TNO) 2000 CR105 has a semimajor axis of 220 ± 1 AU and perihelion distance of 44.14 ± 0.02 AU, beyond the domain which has heretofore been associated with the “scattered disk” of Kuiper Belt objects interacting via gravitational encounters with Neptune. We have also firmly established that the TNO 1995 TL8 has a high pe...

Methods: A new iPad application (app) based on a random dot stereogram was designed for screening stereopsis at multiple distances. Sixty-five subjects with no ocular diseases and wearing their habitual correction were tested at two different distances: 3 m and at 0.4 m. Results were compared with other commercial tests: TNO (at near) and Howard Dolman (at distance) Subjects were cited one week...
