    Abstract: An apparatus and method for estimation of a system having state variables representing the state of the system comprising predicting the estimate of the state variables along with the uncertainties in the state variables; observing a measurement of at least one state variable corrupted with some amount of error; updating the estimates of the state variables using a weighted average, with more weight being given to estimates with higher certainty; and providing an estimator input to update the estimates of the state variables, the estimator input operating to provide asymptotic convergence of the mean estimation error in all of the state variables in the presence of persistent excitation or disturbance that is not asymptotically decaying to zero.

    Abstract: A ring-shaped transistor includes a set of gates. Each gate of the set is disposed between a corresponding source and a corresponding drain. The set of gates are arranged such that all of the set of gates cannot be aligned with fewer than three imaginary straight lines drawn through the gates, with one of the imaginary straight lines passing only once though each of the set of gates.

    Abstract: Porous silicon (PS) films composed of pores with diameters less than 3 nm are fabricated using a galvanic etching approach that does not require an external power supply. A highly reactive, nanoenergetic composite is then created by impregnating the nanoscale pores with the strong oxidizer, sodium perchlorate (NaClO4). The combustion propagation velocity of the energetic composite is measured using microfabricated diagnostic devices in conjunction with high-speed optical imaging up to 930,000 frames per second. Combustion velocities averaging 3,050 m/s are observed for PS films with specific areas of ˜840 m2/g and porosities of about 65-67%. Galvanic etching may also be used to fabricate other porous silicon morphologies and also strong oxidizers other than NaClO4 could be used to create a nanoenergetic porous silicon composite.

    Abstract: A novel methodology for characterizing and calibrating an entangled photon distribution system is disclosed. The entangled photon distribution system includes at least a source of entangled photon pairs, two photon detectors which detect photons among two channels and a controller. The methodology includes: for at least two different operational setting levels of the source of entangled photon pairs, measuring count rates for photons detected by the two photon detectors, individually and coincidently; fitting the measured individual and coincidence count rate data for the at least two different operational setting levels with theoretical models of detection probability; and determining operational parameters of the system from the fitting. The determined operational parameters of the system include the rate of generated entangled photon pairs by the source, the rates of Raman-scattered photons generated in the first and second channels, respectively, and the efficiency of the two photon detectors, respectively.

    Abstract: A photodetector comprising a contact layer; an absorbing region positioned such that light admitted passes into the absorbing region; a diffractive region comprising at least one diffractive element operating to diffract light into the absorbing region; the configuration of the photodetector being determined by computer simulation to determine an optimal diffractive region and absorbing region configuration for optimal quantum efficiency for at least one predetermined wavelength range, the diffractive region operating to diffract light entering through the contact layer such that phases of diffracted waves from locations within the photodetector including waves reflected by sidewalls and waves reflected by the diffractive elements form a constructive interference pattern inside the absorbing region. A method of designing a photodetector comprises using a computer simulation to determine an optimal configuration for at least one wavelength range occurring when waves reflected by the diffractive element form a constructive interference pattern inside the absorbing region.
