Powerful information processing devices called, neural networks, are currently being applied to problems in speech recognition, computer vision, multi-dimensional probability density function estimation, combining uncertain knowledge, and other difficult information processing problems. the research… More

We intend to explore the viability of neural networks for image compression and pattern classification in an integrated system. this is a new approach to image compression that has several advantages over standard approaches. so far, neural networks have been shown to be comparable to standard… More

Existing robotic motion control technology is limited in its ability to handle dynamic effects (such as changing payloads, increased friction due to wear, etc.) without a degradation in performance. in addition, the techniques currently used for repositioning endeffectors in space cannot handle… More

The proposed research is concerned with developing an intelligent tutor which goes beyond static context-sensitive help screens. netrologic's proposed system will judge the epistemic state of a user and devise alternative goal-directed strategies. the expertise of the intelligent tutor will cover… More

It is presently very difficult for a deaf person to serve ona jury or as a lawyer in a court room. the only means of providing the information about the proceedings is with an interpreter capable of using sign language. this proposal suggests the possibility of using the court recorder as a means… More

Netrologic's phase i will develop a preliminary design of a natural language interface to a geographical information system (gis). netrologic's design will be based on state-of-the-art artificial intelligence natural language and dialog modeling research. phase i will include a close study of a… More

The fundamental objective of netrologic's proposed research is to specify a mobile robotic aircraft inspection system which is reliable, adaptive, user friendly and cost-effective. when such a system becomes available to the nation's airlines it will enable more frequent, faster and more accurate… More

This project will develop a mechanically actuated device with a tactile surface. it will provide a braille interfacerepresenting the same information that a video monitor provides to a sighted person. the braille will be implemented by a grid of solenoids driven by an ibm pc compatable hardware… More

The long-term objective is to enable chemists to scan chemical structures and have a computer provide accurate and timely identification of the structure. this is proposed to be done by scanning in a chemical symbol using anormal scanning process and shipping the resultant digitizedimage to a… More

Research work on manipulator control has been concentrated on developing continuous-time centralized control schemes. in practice, robots are controlled by digital computers and the solution of the control problem based on the assumption of continuous time operation can lead to degradation of… More

We propose to improve image compression techniques which are based on fractal constructions. our approach builds on a line of research begun hutchinson in the early 1980's. barnsley and his co-workers later applied these ideas to the representation image data. barnsley's constructions are mainly… More

The investigtion has the following objectives: 1) establish that microcomputers can quickly provide high quality solutions to large-scale vehicle routing and scheduling problems, 2) demonstrate that neural networks and genetic search can work synergistically with heuristic mathematical algorithms to… More

The objective of the proposed research is to develop an artificial-intelligence fault-diagnostic system that will classify, in real-time, nuclear power plant transients and provide error bounds on its diagnoses. the goal is to develop an artificial neural network (ann) paradigm that is capable of… More

This project introduces a new class of robot manipulators called extenders. extenders are worn by humans and increasehuman mechanical ability while the human's intellect serves as the central intelligent control system for manipulating the extender. the human body, in physical contact with the… More

Netrologic will use the continuous wavelet transform to operate on seismic signals in phase i. we will use the cwt to produce a sythesized signal which is represented with elements of both time and frequency domain. this representation will be fed to a cascade correlation network which will be… More

Machine cutting of threads is a key step in reliably manufacturing many products. however, little progress has been made in improving this process for decades due to the complexity of the process and the difficulty in precisely controlling it. netrologic proposes using non-linear piezoactuators… More

Under this program the current and planned lubrication system design approaches for advanced gas turbine engines such as those being developed under the integrated high performance turbine engine technology (ihptet) initiative will be reviewed, the available lubrication system performance data will… More

Netrologic will deliver a tdd/ascii mode to voice interface for a personal computer whose purpose is to allow the deaf and blind to communicate with each other. at the end of phase i netrologic will deliver and install on an ed computer a system which will allow a deaf user to send a message to a… More

Searches of free text databases depend on the keywords used in the request for information. If keywords are extracted from the user's query and no use is made of synonyms, relevant data in the database may be overlooked. The same can be the case if class-subclass, and part-whole information is… More

Netrologic proposes to build a navigation system for ships which integrates gps and loran-c. the gps system provides asf error correction to loran-c so that the corrected loran-c is able to furnish near gps quality geographical location information. in areas where dgps is available the dgps signal… More

NETROLOGIC proposes to build a system which has the ability to self-modify its own architecture such - that it will learn to fuse data from disparate sources into a smoothly integrated information base containing all - the information that the system was able to extract regarding the features to… More

Current data rates for use on IR/EO LOROPS or ATARS platforms can exceed 120Mb/s, and, thus, a digital image sequence must be coded prior to transmission and storage. To remove the redundant information, which always exists in image sequences, most video compression techniques use 2D coding to… More

Until recently, digital transmission of high-quality images was limited to special high- bandwidth communication links, but even these kinds of channels cannot provide for real- time transmission of high-rate image sequences. Thus, a digital image sequence must be coded prior to transmission and… More
