New materials such as continuous fiber reinforced aluminum matrix composites exceptional performance, but often at the expense of incompatibility with conventional joining techniques. Spacecraft structures require high stiffness for stable structures and launch vibration resistance, as well as low outgassing characteristics, especially when cryogenic sensors are in use on the spacecraft. Solutio ...

The development of a microwave curing method for resin matrix composites and jointing/bonding epoxy is proposed. This technique will take advantage of the ability of vapor-grown carbon fiber (VGCF) to absorb microwave energy with high efficiency. By adding VGCF to resin matrix composite material and epoxy, we hope that the materials can be processed by microwave irradiation in a manner that result ...

Arca Systems proposes to initiate the design and development of an intrusion detection system for the GCCS LES (and similar environments). Many current intrusion detection tools are Unix-based, focused on a single host or on a generally homogeneous distributed environment. The notional GCCS LES environment makes extensive use of distributed architecture, using support from the COTS technologies ...

Arca proposes research leading to development of a suite of methodology support products to help meet the need for innovative assurance techniques appropriate for emerging information technologies. The product will consist of a licensable methodology and supporting materials for specifying, building, and evaluating assurance arguments for products and systems based on the capability of security en ...

In the last several years there has been an explosion of information regarding the nature of peptide antigens expressed on human tumors together with class I molecules encoded in the Major Histocompatibility Complex (MHC) and recognized by cytotoxic T lymphocytes (CTL). One very successful approach aimed at the identification of these antigens, termed Direct Identification of Relevant Epitopes for ...

DESCRIPTION (Investigator's Abstract): The application proposes to engage in teacher education workshops focussing on issues pertaining to drug abuse particularly the neurobiology thereof. Workshops will be provided for teachers from experts in the field. Our main goal in this science education project is to impart useful knowledge and information to teachers of grades 7 -12. In an era of de ...
