METALS ARE AMONG THE MOST WIDELY USED RAW MATERIALS IN TODAY'S INDUSTRIAL SOCIETY. CONSEQUENTLY WASTEWATERS FROM METAL-PRODUCING AND METAL-CONSUMING INDUSTRIES CONTAIN HIGH CONCENTRATIONS OF METALS. IN ADDITION TO THE WATER CONTAMINATION PROBLEM, THE METALS LOST ARE EXTEMELY VALUABLE. ANNUAL LOSSES OF PRECIOUS METALS FROM JUST ONE SEGMENT OF THE INDUSTRY - JEWELRY MANUFACTURING - ARE ESTIMATED AT ...

DETAILED AND PRECISE MEASUREMENTS OF AEROSOL CHEMICAL AND PHYSICAL PROPERTIES ARE NECESSARY IN ORDER TO UNDERSTAND FORMATION PROCESSES AND ASSESS ENVIRONMENTAL IMPACTS SO THATCOST-EFFECTIVE CONTROL STRATEGIES CAN BE FORMULATED. SULFATE AEROSOL IS OF PARTICULAR CONCERN DUE TO ITS INVOLVEMENT IN ACID DEPOSITION, VISIBILITY REDUCTION AND ADVERSE HEALTH EFFECTS. INSTRUMENTATION FOR SUCH AEROSOL MEASUR ...

RF SUPERCONDUCTIVITY HAS BEEN VERY SUCCESSFULLY APPLIED TO HEAVY-ION ACCELERATORS. HOWEVER, TO INCREASE THE CAPABILITYOF EXISTING ACCELERATINO FACILITIES TO HIGHER ENERGIES, NEW ACCELERATING STRUCTURES OPTIMIZED FOR FAST IONS WILL HAVE TOCOME INTO EXISTENCE. WE PROPOSE TO DETERMINE A SET OF SUPERCONDUCTING ACCELERATING STRUCTURES WHICH WOULD EFFICIENTLY ACCELERATE HEAVY IONS UP TO A VELOCITY OF 0. ...

THE USE OF NON-UNIFORM MODULATION VECTOR SPACING TO OVERCOMESEQUENTIAL DECODER COMPUTATIONAL DEFICIENCIES IS INVESTIGATED. TRADITIONAL CONVOLUTIONAL (SEQUENTIAL) DECODING TECHNIQUES CAN PROVIDE ARBITRARILY LOW OUTPUT ERROR RATES WITH A LONG CONSTRAINT LENGTH CODE. HOWEVER, BURSTS OF NOISE OR FADES CAN OVERBURDEN THE DECODER, AS INCOMING DATA OVERFLOW THE DECODERS (FINITE) BUFFER MEMORY. A SHORTER ...

THE PRESENT BISTATIC OPTICAL STEREOSCOPIC SYSTEMS USING TRIANGULATION APPROACH HAVE ONE SERIOUS DRAWBACK: AT SHORT DISTANCES BOTH SENSORS MAY NOT NECESSARILY BE EXPOSED TO THESAME REGIONS OF A COMPLEX OBJECT. A SINGLE ULTRASONIC SENSOR IS SUFFICIENT TO MEASURE DISTANCES TO AN OBJECT. ADVANTAGES OF ULTRASONIC SENSOR ARE ITS LOW COST AND HIGH PRECISION OF SHORT RANGE MEASUREMENTS. EFFECTIVE USE OF U ...

THE FEASIBILITY OF USING BELIEF FUNCTIONS IN DEALING WITH UNCERTAINTY IN EXPERT SYSTEMS IS EXAMINED. THE TWO KEY AREAS FOR PROPOSED RESEARCH ARE THE PROPAGATION OF UNCERTAINTY AND THE COMBINATION OF UNCERTAIN INFORMATION. THE PROPOSED RESEARCH ON THE PROPAGATION OF UNCERTAINTY WILLBE BASED ON GENERALIZING THE NOTION OF IF-THEN FULES TO PROBABILISTIC TRANSITIONS; THE PROPOSED RESEARCH ON COMBINING ...

A RATE LIMITING FACTOR TO USEFUL GENETIC ENGINEERING IN PLANTS IS THE ISOLATION OF PLANT GENES WHICH CONFER AGRONOMICALLY IMPORTANT PROPERTIES TO CROP PLANTS. TRADITIONAL GENE ISOLATION PROCEDURES WHICH ARE BASED ON A KNOWLEDGE OF THE GENE PRODUCT ARE OF LIMITED USE BECAUSE THEBIOCHEMICAL BASIS OF IMPORTANT PROPERTIES SUCH AS DISEASE RESISTANCE, FERTILITY AND YIELD ARE UNKNOWN. THIS PROPOSAL DESCR ...
