Despite more that 50 years of study, the processes that heat and accelerate solar plasmas to form the corona and solar wind are still not well understood. We study the manifestations of plasma structures rooted in the solar atmosphere and model the transport of energy therein based on models of the discrete structures that may mediate this process. To further facilitate study of these phenomena, we have also contributed to the development of novel CCD technologies that allow observation of solar EUV emissions with excellent sensitivity and spatial fidelity.
The goal of the proposed research is to increase the sensitivity and collection efficiency of optical-antenna-coupled detectors by gaining a practical understanding of the relevant design parameters in the nanoscale regime, and by designing impedance matched optical antennas and antenna-sensor combinations. Employing recently developed near-field probe techniques, the proposal team will measure high-spatial-resolution, three-dimensional maps of vector electric field in close proximity to optical antennas, yielding the unique ability to extract complex impedance of optical antennas and sensors.
The world is being controlled by voice activation and speech recognition that requires a physical trigger or button press. That distinction is fading away because we have developed the (Wake-Up-Word) technology that would allow recognition of voice commands without a physical prompt. It is a specific way of using speech recognition to "trigger" required and necessary action using only speech instead of push-to-talk buttons. The system is capable of understanding the context of the utterance:"Computer!", "Take me to the 4th floor" from: "I have a powerful computer on my desk".
The design of spacecraft, satellites, planetary landers and their missions is becoming ever more complex and challenging. At the heart of this design process is Systems Engineering. New methods, techniques and tools that can be used for spacecraft design from a Systems Engineering perspective are being developed and tested at Florida Institute of Technology. Florida Tech researchers and students are closely teaming with NASA’s Jet Propulsion Laboratory to develop a ‘Mission Observer CubeSat’ using the new Systems Engineering tools and techniques.
Antenna-coupled detectors for THz and IR imaging arrays hold great promise for the development of next-generation imagers by providing the collection cross-section of an antenna and transferring collected power to a subwavelength detector. The primary goals of this research are (1) to increase the THz/IR sensitivity and collection efficiency of antenna-coupled detectors through the design of IR impedance matching networks integrated with antenna designs, and (2) the development of low-loss THz/IR waveguides/phase shifters.
