As part of the Army's Demo III project, a sensor-based system has been developed to identify roads and to enable a mobile robot to drive along them. A ladar
4D/RCS consists of a multi-layered multi-resolutional hierarchy of computational nodes each containing elements of sensory processing (SP), world modeling (WM)

This paper describes a world model that combines a variety of sensed inputs and a priori information and is used to generate on-road and off-road autonomous
In this paper, we will describe a value-driven graph search technique that is capable of generating a rich variety of single and multiple vehicle behaviors. The

NIST, Sandia National Laboratories, and International SEMATECH are developing a new type of linewidth standard for calibrating Critical Dimension (CD) metrology
A cost-based admission control and routing scheme admits an arriving request on the minimum cost route if this cost does not exceed the cost of the request, and
The TREC question answering track is an effort to bring the benefits of large-scale evaluation to bear on the question answering problem. In its third year, the
A computationally convenient Green's function method is described forcalculation of strain characteristics of quantum dots in an anisotropic semi-infinite solid
The 6-Degree of Freedom Tri-Stage Micro Positioner (6DFTSMP) can generate high accuracy, small displacement, and high-resolution motions. The moving platform of

Linux is being used increasingly for real-time control of industrial equipment. Versions of Linux adapted to support deterministic task execution are freely
A new linear prediction method that improves IDDQ test effectiveness is described. The method uses statistical pre-processing of exhaustive measurements on
Methods were developed to calculate empirical models for device error behavior from data sets with missing data. These models can be used to develop reduced

The performance of face recognition algorithms is recently of increased interest, although to date empirical analyses of algorithms have been limited to rank
Some organometallic compounds of iron are two orders of magnitude more effective at volume fraction than CF 3Br in premixed flames, an order of magnitude more
Polyurethanes (PU) are used extensively as exterior building materials. However, PU undergoes degration during outdoor exposure. The quantum efficiency of
There has been a long history of research in text summarization by both the text retrieval and the natural language processing communities, but evaluation of
Secure application systems are often built using the Software Architecture of the system as a blue print. The Software Architecture of any application system
The investigation into reducing overall vehicle weight by replacing conventional steel sheet metal with lightweight materials has been initiated. However
