The Phase I of this effort has proven key concepts of our proposed comprehensive health management solution: namely remote and shadow diagnosis over low-bandwidth network and prognosis based on statistical techniques. Our telediagnosis solution has been demonstrated to Honeywell and NASA-JSC, and is being considered for remote monitoring of the Space Station. It is also the centerpiece of Honeywel ...

The ?space adaptation syndrome? develops in conditions in which nauseogenic stimuli are present for a long period. The perceptual situation of an astronaut exposed to unusual gravitational-inertial forces has been compared to that found in experiments involving perceptual rearrangement, such as optically induced displacement, curvature, tilt, or right-left reversal. In both instances, the observer ...

Aircraft icing severity depends on two key cloud parameters, liquid water content and droplet size. Proposed is a simple instrument using multiple hot wire elements to measure cloud droplet size (median volume diameter) and liquid water content.The unit utilizes three hot wire sensor elements each of a different geometry, all exposed to the same airflow. By virtue of their different sizes/shapes, ...

70302 Microalgae technologies that not only would produce renewable fuels but also would mitigate greenhouse gases are being developed in the U.S. and abroad. A central R&D issue is the design of the culture systems, which can be of two general types: open ponds and closed photobioreactors. A direct experimental comparison of their attributes is required in order to continue the development ...

70733 Because the growth of primary tumor and metastatic lesions beyond a few millimeters requires formation of new blood vessels (angiogenesis), the targeted delivery of cytotoxic drugs to growing tumor blood vessels may form the basis for a highly selective anti-cancer therapy. Particularly attractive are two-step therapies that initially deliver relatively non-toxic ¿prodrugs¿ that a ...

"Despite recent advances in hardware and software tools for modeling and simulation, significant limitations still exist in the ability to quickly create and render geospecific visual terrain databases (TDB's). Existing capabilities to generate terraindatabases are often tied to classified databases that cannot be used for many general-purpose applications. Worldwide coverage can only be provided ...

Pulse detonation engines hold promise to increase performance of air-breathing propulsion systems by taking advantage of the increase in cycle efficiency due to the constant-volume heat addition characteristics of detonative combustion. A pulse detonation engine (PDE) produces thrust through the high pressure of detonation to achieve improved efficiency relative to other, more traditional propulsi ...

65549 Conventional duct systems in houses have serious deficiencies. Usually, they are located in very hot or very cold attics with little insulation to protect them, and often they have excessive leaks and construction-caused defects. These problems result in energy losses, widely fluctuating indoor comfort conditions, and the transport of air-borne contaminants from unconditioned to condi ...
