NASA JSC neural network survey results
A survey of Artificial Neural Systems in support of NASA's (Johnson Space Center) Automatic Perception for Mission Planning and Flight Control Research Program was conducted. Several of the world's leading researchers contributed papers containing their most recent results on artificial neural systems. These papers were broken into categories and descriptive accounts of the results make up a large part of this report. Also included is material on sources of information on artificial neural systems such as books, technical reports, software tools, etc
Intensional Cyberforensics
This work focuses on the application of intensional logic to cyberforensic
analysis and its benefits and difficulties are compared with the
finite-state-automata approach. This work extends the use of the intensional
programming paradigm to the modeling and implementation of a cyberforensics
investigation process with backtracing of event reconstruction, in which
evidence is modeled by multidimensional hierarchical contexts, and proofs or
disproofs of claims are undertaken in an eductive manner of evaluation. This
approach is a practical, context-aware improvement over the finite state
automata (FSA) approach we have seen in previous work. As a base implementation
language model, we use in this approach a new dialect of the Lucid programming
language, called Forensic Lucid, and we focus on defining hierarchical contexts
based on intensional logic for the distributed evaluation of cyberforensic
expressions. We also augment the work with credibility factors surrounding
digital evidence and witness accounts, which have not been previously modeled.
The Forensic Lucid programming language, used for this intensional
cyberforensic analysis, formally presented through its syntax and operational
semantics. In large part, the language is based on its predecessor and
codecessor Lucid dialects, such as GIPL, Indexical Lucid, Lucx, Objective
Lucid, and JOOIP bound by the underlying intensional programming paradigm.Comment: 412 pages, 94 figures, 18 tables, 19 algorithms and listings; PhD

Logical behaviors
technical reportIn this paper we describe an approach to high-level multisensor integration in t h e context of an autonomous mobile robot. Previous papers have described the development of t h e INRIA mobile robot subsystems: 1. sensor and actuator systems 2. distance and range analysis 3. feature extraction and segmentation 4. motion detection 5. uncertainty management, and 6. 3 -D environment descriptions. We describe here an approach to: ? the semantic analysis of the 3-D environment descriptions
