Hematopoiesis, the regulated production of mature blood cells, is a complex scheme of multilineage differentiation which occurs mainly in the bone marrow of adult mammals. Mature cells are continuously produced from progenitor (or precursor) cells. Consequently, assays which detect these progenitor cells are vital in many research and clinical settings. The current assay procedures suffer from a n ...

The objective of this project is to use the newest advance in the technology of Ferroelctric Liquid Crystal (FLC) displays so that they can be used for Visual Landing Aids as well as other applications. Currently FLC's suffer from serious mechanical and temperature limitations due to the fact that mechanical stress alters the structure of the liquid crystal material. We propose to stabilize the ce ...

The objective of this project is to develop a system for the optimized viewing of medical x-ray film. Illuminators currently used to view radiographs have a fixed-area, spatially uniform light output. This allows extraneous light to degrade visual performance and limits the viewable film density range to the dynamic range of the eye at a given adaptation level. The proposed viewing system will pro ...

NAVIGATION OF FIELD MOBILE ROBOTIC SYSTEMS REQUIRES A MEANS FOR THE ROBOTIC SYSTEM TO DETERMINE ITS ABSOLUTE LOCATION. THE USUSAL MEANS IS TO USE A VEHICLE INTERTIAL GUIDANCE SYSTEM WHICH IS PERIODICALLY UPDATED BY A GPS OR LORAN C RECEIVER. UNFORTUNATELY, GPS AND LORAN CAN ONLY PROVIDE ABSOLUTE POSITIONAL ACCURACY TO WITHIN 5 METERS OR SO WHICH LIMITS THE COMBINED INS/GPS/LORAN SYSTEM TO ABOUT TH ...

MOBILE ROBOT SYSTEM NAVIGATION IS A DIFFICULT PROBLEM UNDER ANY CIRCUMSTANCES. OUTSIDE NAVIGATION USING COMPUTER VISION-BASED METHODS REQUIRES RECOGNITION OF VARIABLE TERRAIN FEATURES OR THE USE OF A RADIO LOCATION SYSTEM SUCH AS A GLOBAL POSITIONING SYSTEM. INDOOR NAVIGATION IS TYPICALLY ACCOMPLISHED WITH A COMBINATION OF PROXIMITY SENSORS (USUALLY SONIC) AND ARTIFICIAL GUIDANCE TARGETS IMPLEMENT ...

Due to the increasing use of technology to plan and implement modern day combat, it is imperative that troop and vehicles deployment and position be known as precisely as possible. Furthermore, the unit commander must be able to quickly plan, transmit, and display friendly and adversarial troop and vehicle locations to coordinate battlefield operations effectively in the heat of battle. In this ef ...

THIS RESEARCH PROJECT IS DIRECTED AT DEVELOPING AN OPERATOR PERCEPTION MODEL BASED ON INSIGHT FROM EMPIRICAL PERCEPTION DATA COMBINED WITH KNOWLEDGE OF HOW THE HUMAN VISION SYSTEM PROCESSES INFORMATION. AS A FIRST STEP IN THIS DIRECTION, WE ARE PROSPOSING TO COLLECT PERCEPTUAL DATA AND USE THIS DATA TO DEVELOP, IMPLEMENT, AND EVALUATE CONCEPT APPROACHES FOR AUGMENTING HUMAN OPERATOR PERFORMANCE IN ...
