Social network analysis is a powerful method for making sense of an increasingly interconnected world. Developing social network analysis tools requires datasets with which to test them, but sharing datasets is problematic because of privacy issues. Initial attempts to anonymize network datasets proved ineffective due to de-anonymization attacks that leveraged publically available information to i ...

In this SBIR program, TeraDiode, Inc. will develop a record brightness fiber-coupled diode laser system for pumping high power fiber lasers. TeraDiode has an exclusive license on intellectual property developed at MIT Lincoln Laboratory on a means of combining many diode lasers while scaling the brightness, to obtain an exceptionally bright fiber-coupled diode laser system. TeraDiode will demons ...

Biologically-inspired motions such as flapping, perching, walking, running, swimming, grasping and manipulating, are difficult for the most advanced robots today. The primary limitation comes from actuation technology in terms of stress/strain ratio delivered to the joint by the actuator overcoming specific resistance. Electromagnetic motors have low torque at high speeds and hence cannot be used ...

In this phase I proposal, we seek a solution to the problem of wiring sensors and actuators on periphery of a robot"s frame(i.e. those positioned to make contact with environment). We will accomplish this using printing technologies and a new proprietary layered carbon fiber forming technology. Because we will enhance segments from CyPhy Works UAV with this technology, this project will have a ...

WHILE THE THEORETICAL BOUNDS ON THE ENERGY STORED BY AND THE POWER OUTPUT OF ELECTROCHEMICAL POWER SOURCES ARE WELL DEFINED BY THERMODYNAMIC AND PHYSICAL CONSIDERATIONS, THE DEGREE TO WHICH ONE CAN APPROACH THE THEORETICAL BOUNDS IS DETERMINED BY CONTRAINTS IMPOSED BY THE DESIGN OF THE ELECTRODES AND PACKAGING MATERIALS. THIS RESEARCH DEALS WITH AN INNOVATIVE CONCEPT FOR MATERIALS AND PACKAGE DESI ...

THE LACK OF A PROCESS TO DOPE ZNS(X)SE(1-X) FOR P-TYPE CONDUCTIVITY IS THE MAJOR OBSTACLE TO THE ADVANCEMENT OF DEVICE TECHNOLOGY BASED ON WIDE BANDGAP P/N HOMOJUNCTIONS. OF PARTICULAR IMPORTANCE ARE LIGHT-EMITTING DIODES AND INJECTION LASERS FABRICATED FROM ZNSXSE(1-X) WHICH OPERATE IN THE BLUE OR ULTRAVIOLET REGIONS OF THE SPECTRUM, ESSENTIAL FOR SOME TYPES OF SOPHISTICATED COMMUNICATION. SPIRE ...

WAVEGUIDE CO(2) LASERS HAVE FOUND MANY TACTICAL DOD APPLICATIONS RECENTLY. THE OUTPUT POWER OF A SINGLE WAVEGUIDE CO(2) LASER IS LIMITED TO ABOUT 40 W C.W. DUE TO GAIN SATURATION AND WAVEFRONT ABERRATIONS. IN THE SAME SIZE PACKAGE AN ARRAY OF WAVEGUIDES COULD BE EXCITED POTENTIALLY PRODUCING AN M X N INCREASE IN THE TOTAL OUTPUT POWER AND, IF THEY WERE PHASE-LOCKED, POTENTIALLY ALMOST AN (MXN)2 IN ...

THIS PROPOSAL IS TO EXPERIMENTALLY INVESTIGATE THE SURFCE DISCHARGE TO PREIONIZED PULSED CARBON DIOXIDE LASERS. IN THIS APPROACH DIELECTRIC ELECTRODES ARE EMPLOYED FOR THE MAIN DISCHARGE, AND A SURFACE DISCHARGE ALONG THE SURFACE OF A DIELECTRIC ELECTRODE PREIONIZES THE GAS VOLUME PRIOR TO THE PRIMARY DISCHARGE. THIS SURFACE DISCHARGE APPROACH ELIMINATES THE NEED FOR A SEPARATE PREIONIZATION SOURC ...

THE DEVELOPMENT OF A LOW COST LASER BEAM WRITER THAT COULD GENERATE LITHOGRAPHIC PATTERNS AT HIGH SPEED WOULD BE OF SIGNIFICANT BENEFIT IN THE DEVELOPMENT OF HIGH-QUALITY, HIGH EFFICIENCY, BINARY OPTICAL COMPONENTS AND SUBSYSTEMS. IT IS PROPOSED TO INVESTIGATE A NEW CONCAPT FOR A HIGH EFFICIENCY IMAGING PROTOTYPE LASER BEAM WRITER AND DEVELOP A LABORATORY PROTOTYPE TO DEMONSTRATE ITS FEASIBILITY. ...
