COAL IS AN ATTRACTIVE FUEL FOR RAILROAD LOCOMOTIVES BECAUSE OF ITS DOMESTIC ABUNDANCE AND LOW COST PER UNIT OF HEAT. ONE RESTRAINT IN COAL AS A LOCOMOTIVE FUEL IS ENVIRONMENTAL POLLUTION. CONSIDERING THESE CONFLICTING CONDITIONS OF ATTRACTIVENESS AND DIFFICULTY IN USING COAL AS A FUEL, IT BECOMES QUITE IMPORTANT HOW THE COAL IS HANDLED AND CONVERTED TO HEAT FOR LOCOMOTIVE POWER. A STUDY OF HEAT EN ...

A SIX MONTH PROGRAM IS PROPOSED TO DEVELOP RIGID SYNTOCTIC POLYIMIDE FOAM PANELS POSSESSING FLAME RESISTANCE, NO-SMOKE EMISSION AND LOW THERMAL CONDUCTANCE FOR REPLACING INTERIOR MATERIALS OF TRANSPORTATION VEHICLES NOW DESIGNATED AS POTENTIALLY HAZARDOUS. AT LEAST FOUR CANDIDATE MATERIALS WILL BE PREPARED AND TESTED TO SELECT THE MOST PROMISING CANDIDATE FOR SCALE-UP IN A PHASE II PROGRAM.

Mechanical damage (typically from third party excavations) is the most frequent source of leaks and ruptures in pipelines. The most common type of mechanical damage is dents, sometimes associated with secondary features such as gouges, external corrosion, or cracks. Currently used techniques for assessing dents are not accurate enough for reliable determination of fitness for service. In this p ...

SOLAR ELECTRICAL GENERATION CELLS ARE SUBJECT TO RADIATION AND THERMAL BREAKDOWN FROM EXPOSURE. THE PURPOSE OF THE PRESENT STUDY IS TO IMPROVE THERMAL STABILITY OF ELECTRONIC EQUIPMENT IN ENERGY-EFFICIENT STRUCTURES. OBJECTIVES ARE TO DESIGN, CONSTRUCT AND TEST AN INNOVATIVE PROTECTIVE SYSTEM FOR SOLAR COLLECTORS THAT WILL IMPROVE THE THERMAL STABILITY AND RADIATION DETERIORATION OF SUCH CELLS. A ...

THE PROPOSED RESEARCH WILL DEMONSTRATE THE APPLICATION OF A NOVEL NON-DESTRUCTIVE EVALUATION TECHNIQUE KNOWN AS SHEAROGRAPHY IN FLAW DETECTION AND CHARACTERIZATION IN STUCTURAL MATERIALS. THIS NOVEL TECHNIQUE EMPLOYS A MONO CHROMATIC LIGHT SOURCE (E.G. A LASER) AND AN OPTICAL DE DETECTION SCHEME TO REVEAL, DISCERN AND CHARATERIZE ANY ST STRESS AND STRAIN CONCENTRATION INDUCED BY DEFECTS IN MA MATE ...

THE PROPOSED PHASE I PROGRAM IS A FEASIBILITY STUDY MERCIAL SHIPS. SENSOR SYSTEMS TO BE ASSESSED WILL BE BASED ON THE INNOVATIVE METHOD OF S&S ASSOCIATES. IN THIS METHOD, TORQUESTRANSMITTED OVER A ROTATING SHAFT IN THE POWER SYSTEM ARE DETERMINED DIRECTLY FROM FIRST PRINCIPLES IN TERMS OF QUANTITIES MEASURED DURING THE SYSTEM'S NORMAL OPERATION. THE ENGINE PUTPUT TORQUE, LOAD TORQUE, ADN CHANGES I ...

A STUDY CONDUCTED BY INTERVIEWS WITH MANAGEMENT FROM PUBLIC AND PRIVATE TRANSIT OPERATORS AND METROPOLITAN PLANNING ORGANIZATIONS (MPOS) INTENDED TO DETERMINE THE FEASIBILITY AND BENEFITS OF ACCOMPLISHING FIVE OBJECTIVES IN SUBSEQUENT RESEARCH. THE OBJECTIVES ARE TO: 1. IDENTIFY THE RELATION SHIP BETWEEN EXCELLENCE IN THE PROVISION OF TRANSIT AND THE USE OF CONTRACTING WITH THE PRIVATE SECTOR; 2. ...
