High-frequency acoustic modems are required to provide undersea communication networks to support covert surveillance operations. These modems can also be used as platforms for compact, low power surveillance sensors and processing. A natural first step would be to integrate a capability for passive acoustic detection of ships and submarines. A multi-phase effort is proposed for integrating passiv ...

GAS-ASSISTED INJECTION MOLDING PROCESS HAS BEEN CLAIMED BY ITS PROPONENTS AS THE MOST IMPORTANT DEVELOPMENT FOR THE INJECTION MOLDING PROCESS SINCE THE INVENTION OF RECIPROCATING-SCREW INJECTION MOLDING MACHINE. THIS PROCESSCONSISTS OF A PARTIAL INJECTION OF POLYMER MELT TO THE MOLD CAVITY FOLLOWED BY AN INJECTION OF COMPRESSED GAS WHICH PENETRATES AND, IN PRINCIPLE, HOLLOWS OUT A NETWORK OF PRE-D ...

ENVERTHING FROM COMPUTERS AND CONSUMER ELECTRONICS TO MILITARY EQUIPMENT IS DRIVEN BY MICROCHIPS, THE FIRST LINK IN THE CHAIN OF TECHNOLOGY FOR THE MICROELECTRONIC INDUSTRY. IN ORDER TO EXTEND THE FLEXIBILITY AND CAPACITY OF DEVICE AND SYSTEM DESIGN, MICROELECTRONIC PACKAGING IS BECOMING AS IMPORTANT AS SILICON FABRICATION. AMONG EXISTING ENCAPSULATION METHODS, PLASTIC PACKAGING CONTINUES TO PLAY ...

Embedded systems are commonly deployed in applications where reliability is critical to operations. More recently the interest in sensor networks has added a requirement for remote access, often over openly accessible or penetrable networks. This creates a need for a defensible embedded platform whose robustness is preserved in the face of external influences ranging from nuisance disruption to ac ...

VARIOUS ACTIVITIES (EDUCATION, GOVERNMENT, RESEARCH) GENERATE LARGE AMOUNTS OF RAW DATA. HOWEVER, DATA IS COLLECTED IN A DISJOINTED AND ISOLATED FASHION (I.E., ACTS, LITERATURE) CREATING BARRIERS IN DATA ACCESS AND DISSEMINATION. THERE IS A CONSENSUS AMONG FAMILIES AND PROFESSIONALS, THAT NEEDS OF INDIVIDUALS WITH DISABILITIES AND SERVICES PROVIDED TO THESE INDIVIDUALS COULD BE GREATLY IMPROVED IF ...

As the global economic competition for qualified workforce increases, our country’s ability to compete effectively in the global marketplace depends on our school systems’ ability to create a competitive workforce. Recently, there has been an increase in expectation on American schools to perform better than ever before in preparing students to meet rigorous educational standards. Keeping in l ...

Electricity generation accounts for greater than 50% of total U.S. farm emissions. Renewable energy sources such as wind and solar power are expensive and unreliable. The fuel costs incurred by U.S. farms are offset by supplemental assistance from the government. Particularly attractive are bio-based approaches which use enzymes or entire cells to directly convert renewable compounds into electric ...

Distribution and abundance of endangered species are adversely affected by changes in the land-use patterns that cause habitat loss, habitat fragmentation, pollution or other disturbances. As sensitivity to human impact on local, regional, and global ecologies increases, researchers, planners, and managers are faced with the task of developing local and regional strategies to safeguard biodiversit ...

The Principle of Least Privilege says that programs should operate with sufficient privilege to get the job done, but no more, in order to minimize the harm that can be done in case of error. The Empirical Privilege Profiler system (EPP) will collect data about privileges actually exercised by running programs and use that data to create a composite abstract privilege profile for the program. Pr ...
