Discrete-event simulation is used by thousands of companies to design new manufacturing systems and to improve the performance of existing ones. Manufacturing systems contain numerous sources of randomness such as machine times to failure and machine repair times, which greatly impact on system performance. If each source of system randomness is not modeled by an appropriate probability distr ...

A COMPUTER-BASED MONITORING AND CONTROL SYSTEM (MCS) PROGRAMMED WITH A NUMBER OF NEURAL NETWORKS IS PROPOSED FOR OPERATIONAL CONTROL OF AN EXISTING SEMI-CLOSED TANK SYSTEM FOR INTENSIVE AQUACULTURAL PRODUCTION OF SESSILE MARINE INVERTEBRATES FOR THEIR HIGH-VALUED METABOLITES FOR NEW MARINE PHARMACEUTICALS. THE AQUACULTURE SYSTEM WILL BE TESTED FOR CULTURE OF THE COLONIAL BRYOZOAN BUGULA NERITINA T ...

A wavelength dispersive x-ray fluorescence detector working in soft x-ray region has been proposed based on the diffraction principles. The detector uses graded multilayers as analyzers and large area detectors for data collection to achieve good energy resolution and to avoid count rate problems encountered by solid state detectors. Furthermore, the detector will be tunable in a wide energy regio ...

SILICON PHOTODIODES WITH STABLE, THEORETICALLY PREDICTABLE QUANTUM EFFICIENCY IN THE XUV SPECTRAL RANGE HAVE BEEN RECENTLY DEVELOPED BY RAJ KORDE AND SCIENTISTS AT NIST. SCIENTISTS AT BESSY AND PTB IN GERMANY HAVE INDEPENDENTLY CONFIRMED THAT THE CALCULATED QUANTUM EFFICIENCY OF THESE XUV SILICON DIODES CAN BE USED FOR THE ESTABLISHMENT OF AN INDEPENDENT RESPONSIVITY SCALE IN THE XUV SPECTRAL RANG ...

WE HAVE RECENTLY DEVELOPED SILICON P-N JUNCTION PHOTODIODES WITH STABLE, THEORETICALLY PREDICTABLE QUANTUM EFFICIENCIES (QE) IN THE VACUUM ULTRAVIOLET TO SOFT X-RAY (XUV) SPECTRAL REGION. ALTHOUGH, THE XUV PHOTODIODES ARE STABLE OVER MOST OF THE SOFT X-RAY SPECTRAL RANGE, THEIR QE WAS FOUND TO DEGRADE BY A PERCENT AFTER EXPOSURE TO 10(14)/CM(2) FLUENCE OF 120 NM PHOTONS. THE QE DEGRADATION HAS BEE ...

In Phase I of the SBIR program, LEEOAT company will develop and optimize the conceptual design and the fabrication process of the far ultraviolet focal-plane-array detector and readout system. Additionally, we will theoretically model the detector and readout system and reduce-to-practice the crucial elements of the innovation. We will estimate the cost/effort for the fabrication and testing ...

This is a Phase 2 proposal to develop an instrument to simultaneously measure particle size, velocity, and concentration in applications characterized by a large size range and high particle concentration. The instrument will be based on the Pulse Displacement Technique whose feasibility was demonstrated during Phase 1. Experiments performed during Phase 1 demonstrated a high accuracy in meas ...
