TECHNIQUES ARE DEVELOPED FOR THE EFFECTIVE HIERARCHICAL CONTROL OF LARGE-SCALE PROCESSES. INDUSTRIAL PROCESSES ARE USUALLY CHARACTERIZED BY SUCH ATTRIBUTES AS LARGE DIMENSION ALITY, THE INTERACTION OF MANY SUBSYSTEMS, MULTIPLE TIME- SCALES DYNAMIC BEHAVIOR, MODEL UNCERTAINTIES, AND CONFLICT ING PERFORMANCE CRITERIA. USING AS AN EXAMPLE THE CONTROL OFA TYPICAL THERMAL PROCESS, FUNCTIONAL REQUIREMEN ...

PRESENT TECHNOLOGY USED TO FORM EPITAXIAL LAYERS OF III-V COMPOUNDS IS LIMITED TO TRADITIONAL ATMOSPHERIC AND REDUCED PRESSURE MO-CVD REACTORS WHICH FAIL TO ACHIEVE THE DEGREE OF LAYER ABRUPTNESS REQUIRED OF SUPER LATTICE STRUCTURES OR MOLECULAR BEAM EPITAXY (MBE) REACTORS WHICH SUFFER FROM LIMITED THROUGHOUT CAPABILITY. THE DEVELOPMENT PROGRAM OUTLINED IN THIS WORK IS AIMED AT DEVELOPING A MULTIS ...

CERTAIN APPLICATIONS IN COASTAL HYDROGRAPHY REQUIRE A SHORT PULSE WIDTH, HIGH REPETITION RATE OUTPUT FORMAT IN THE GREEN SPECTRAL REGION. A DESIGN FOR A SOLID-STATE LASER IS DESCRIBED WHICH WILL GENERATE 5 NANOSECOND PULSES AT AN ENERGY OF 0.5 MJ PER PULSE AND A REPETITION RATE OF 10KHZ. THE OUTPUT WAVELENGTH WILL BE 532 NM. THE ONLY SYSTEM WHICH CURRENTLY CAN GENERATE VERY SHORT PULSES AT THE 10K ...

DESIGN, SIMULATION, FABRICATION, AND EVALUATION OF A PROTOTYPE VERY LARGE SCALE INTEGRATION (VLSI) DATA ACQUISITION SUBSYSTEM IS PROPOSED. AVAILABLE STATE-OF-THE-ART ONE MICRON CMOS TECHNOLOGY MAY ALLOW INCORPORATION OF MORE THAN 128 CHANNELS OF 24-BIT 300 MHZ COUNTERS INTO A SINGLE INTEGRATED CIRCUIT. A PROTOTYPE SYSTEM OF SIMPLE REPEATED CELLS OF COUNTERS, CONTROL AND I/O BUFFERS HAS BEEN DESIGN ...
