The purpose of the present study was to evaluate the effectiveness of subjective and objective probe questions in predicting situation awareness as measured by the Situation Awareness Rating Technique (SART). The data for this evaluation were taken from a previous investigation in which instrumentrated pilots flew automated ILS approaches into the Dallas-Fort Worth (DFW) Airport while monitorin...

In recent years, there have been important developments in the simulation analysis of the mixed multinomial logit (MMNL) model as well as in the formulation of increasingly flexible closedform models belonging to the Generalized Extreme Value (GEV) class. In this paper, we bring these developments together to propose a mixed spatially correlated logit (MSCL) model for location-related choices. ...

PURPOSE To report a case of rainbow glare following femtosecond laser-assisted LASIK (femto-LASIK) with the Wavelight FS-200 femtosecond laser (Alcon Laboratories, Inc., Fort Worth, TX). METHODS A patient was treated bilaterally for myopia with femto-LASIK using the FS-200 femtosecond laser. Postoperatively, he complained of rainbow glare in his right eye. RESULTS Three months postoperative...

The soak-time of vehicle trip starts is defined as the duration of time in which the vehicle’s engine is not operating and that precedes a successful vehicle start. The temporal distribution of the soak-time in an area is an important determinant of area-wide mobile source emissions. In the current paper, we formulate and implement a methodology for modeling soak-time durations. The methodology...

THIS SUMMER, DALLAS, TEXAS, HAS BEEN IN THE CENTER of its worst-ever regional epidemic of West Nile virus (WNV) infection, with one-quarter of the nation’s cases identified in Dallas County. With a record high number of trapped mosquitoes testing positive for WNV, from June 20 to August 21 WNV infections have been confirmed in 270 county residents; 160 have been hospitalized, 51 have required i...

This paper proposes and implements a fractional split model that predicts the VMT mix on links as a function of the functional roadway classification of the link, the physical attributes of the link, the operating conditions on the link, and the attributes of the traffic analysis zone in which the link lies. The fractional split model is an useful formulation for VMT mix analysis because it acc...

Paediatric cataracts are a relatively common (1 to 15 per 10,000 children), but treatable worldwide morbidity [1]. Unfortunately, surgical intervention in children is often more difficult and associated with more complications than in adult patients. The surgical difficulty of Paediatric cataract extraction can be attributed to the increased elasticity of the lens capsule as well as decreased s...

A 70year old male presented with a 2day history of sudden painless decreased vision in the right eye. Other than presbyopia and senile cataracts, there was no significant past ocular history. His past medical history was significant for a cerebral vascular event of unclear origin several years prior. Evaluation revealed a branch retinal artery occlusion. Optical Coherence Tomography (OCT) angio...

The distribution of the duration of trips in a metropolitan area is an important input to estimating area-wide running loss emissions, operating mode fractions and vehicle miles of travel (VMT) accumulated on local roads in the region. In the current paper, we formulate and implement a methodology for modeling trip durations. The approach develops a log-linear regression model of the duration o...
