Although auditory verbal hallucinations are often thought to denote mental illness, the majority of voice hearers do not satisfy the criteria for a psychiatric disorder. Here, we report the first functional imaging study of such nonclinical hallucinations in 7 healthy voice hearers comparing them with auditory imagery. The human voice area in the superior… (More)
— Worldwide air traffic levels are growing at a rate expected to double the current traffic level by 2020. The current technology Air Traffic Control systems are stretched to their limit and are prone to large delays during the peak summer travel season. There is doubt that the current systems can be scaled up to meet the expected demand levels. Many Air… (More)
One of the key services envisioned in support of the NextGen and SESAR concepts is the 4D Trajectory Data Link (4DTRAD) Service, which is being defined by RTCA SC-214 and EUROCAE WG78. One key principle of these concepts is the use of a closed loop clearance from takeoff to landing.
Procedures for Continuous Descent Approach (CDA) and Optimized Profile Descents (OPD) are being fielded to allow aircraft to approach moderately dense terminal areas while flying efficient, near-idle descent trajectories that save fuel, and reduce emissions and noise. However, CDA operations can have a negative impact on the airspace throughput and… (More)
We propose a framework for designers of business organizations and designers of information systems that portrays three forms of " space " that mediate social interactions: physical space, social space and informatic space. The framework aids organizational designers and information technology designers to understand some of the complexities of enabling… (More)
As one of the important modules of ICAO's Aviation System Block Upgrades (ASBU), 4D Trajectory Based Operation (4DTBO) has been recognized as a strategic approach to modernize the Air Traffic Management (ATM) system environmentally with improved flight safety and efficiency. Programs such as FAA's Next Generation Air Transportation System (NextGen) and… (More)
