SUPERCONDUCTING HEAVY-ION BOOSTERS ARE LIMITED IN THEIR MASS RANGE BY THE VELOCITY ACCEPTANCE OF THE RESONATORS IN THEIR FIRST SECTIONS. A NEED HAS ARISEN TO DO NUCLEAR PHYSICS IN MASS RANGES INACCESSIBLE WITH EXISTING ACCELERATING STRUCTURES. THE END PRODUCT THAT WOULD RESULT FROM THIS RESEARCH IS AN ACCELERATING RESONATOR WITH AN UPPER MASS ACCEPTANCE 50% LARGER THAN EXISTING STRUCTURES. OUR EXP ...

THE GROWTH OF GAAS ON SILICON HAS LONG BEEN RECOGNIZED AS A DESIRABLE APPROACH FOR ADVANCE OPTOELECTRONIC DEVICES INCLUDING OPTICAL INTEGRATED CIRCUITS, OPTICAL COMMUNICATIONBETWEEN CIRCUITS AND AS A SOURCE OF LOW-COST GAAS LAYERS FORSOLAR CELL AND DISPLAY APPLICATIONS. PROGRESS ON THE DEVELOPMENT OF THIS TECHNOLOGY HAS BEEN AFFECTED BY STRAINS AND DISLOCATIONS INTRODUCED INTO THE GAAS LAYER BY TH ...

THE INCREASED USE OF COMPUTERS IN STRUCTURAL DESIGN HAS REDUCED THE SAFETY OF OUR BUILDINGS, BRIDGES AND OTHER CONSTRUCTED FACILITIES, AS MORE OF THE ENGINEERING IS TRANSFERRED FROM THE HUMAN TO HIS "BLACK BOX." AN ACCELERATION OF THIS TREND IS ANTICIPATED WITH THE CURRENT INTRODUCTION OF A NEW GENERATION OF "EXPERT" DESIGN SOFTWARE. IN PHASE I, THE RELIABILITY OF EXPERT SYSTEMS FOR STRUCTURAL DES ...

THE SAND IMPACT PROBE (SIP) IS A SENSOR WHICH MEASURES THE CONCENTRATION OF SUSPENDED SAND BY REGISTERING THE IMPACT OFMOVING GRAINS ON A TRANSDUCER. PREVIOUS WORK HAS SHOWN THATTHE UNI-DIRECTIONAL SIP IS A PRACTICAL INSTRUMENT, BUT (A) ITS UNI-DIRECTIONALITY PRECLUDES USE IN REVERSING OR MORE COMPLEX FLOWS, I.E. IN THE SURF ZONE; AND (B) ITS SIZE LIMITS USE CLOSE (WITHIN CENTIMETERS) TO THE BED. ...
