10 MMBt/Hr AFBC Commercial Demonstration Cedar Lane Farms
The objective of this project was to demonstrate and promote the commercialization of coal-fired atmospheric fluidized bed combustion (AFBC) systems, with limestone addition for SO2 emissions control and a baghouse for particulate emissions control. This AFBC system was targeted for small scale industrial-commercial-institutional space and process heat applications in the 4-40 MMBtu/hr size range. A cost effective and environmentally acceptable AFBC technology in this size range could displace a considerable amount of heating gas and oil with coal, while resulting in significant total cost savings to the owner/operators.

16,000-rpm Interior Permanent Magnet Reluctance Machine with Brushless Field Excitation
The reluctance interior permanent magnet (RIPM) motor is currently used by many leading auto manufacturers for hybrid vehicles. The power density for this type of motor is high compared with that of induction motors and switched reluctance motors. The primary drawback of the RIPM motor is the permanent magnet (PM) because during high-speed operation, the fixed PM produces a huge back electromotive force (emf) that must be reduced before the current will pass through the stator windings. This reduction in back-emf is accomplished with a significant direct-axis (d-axis) demagnetization current, which opposes the PM's flux to reduce the flux seen by the stator wires. This may lower the power factor and efficiency of the motor and raise the requirement on the alternate current (ac) power supply; consequently, bigger inverter switching components, thicker motor winding conductors, and heavier cables are required. The direct current (dc) link capacitor is also affected when it must accommodate heavier harmonic currents. It is commonly agreed that, for synchronous machines, the power factor can be optimized by varying the field excitation to minimize the current. The field produced by the PM is fixed and cannot be adjusted. What can be adjusted is reactive current to the …

40-MW(e) Prototype High-Temperature Gas-Cooled Reactor Research and Development Program. Quarterly Progress Report for the Period Ending June 30, 1962
Research and development progress specifically directed toward the construction of a 40-Mw(e) prototype power plant employing a high-temperature, gas-cooled, graphitemoderated reactor known as the HTGR is reported. Irradiation of element III-B in the in-pile loop continued satisfactorily. The element has generated a total of l36.3 Mw-hr of fission heat. The gross activity in the purge stream increased slightly to about 350 mu C/cm/sup 3/. By taking larger gas samples than were previously taken, a value of 0.02 VC/cm/sup 3/ was obtained for the gross activity of the primary loop. Element III-A, which was removed from the loop after generating 133 Mw-hr of fission heat, was disassembled and examined. No fuel-compact damage of any type was visible. Determination of the distribution of fission products in the element is under way, Fissionproduct- release data for in-pile-loop element III-A were calculated. During the 133 Mw- hr of operation, the release fraction increased by approximately one order of magnitude. Also calculated were the xenon and krypton release data for the first 100 Mw-hr of III-B operation. The release rate for the longer-lived isotopes increased bv about a factor of 10 and that of the shorter-lived isotopes by about a factor of 100. A test …

100 LPW 800 Lm Warm White LED
An illumination grade warm white (WW) LED, having correlated color temperature (CCT) between 2800 K and 3500K and capable of producing 800 lm output at 100 lm/W, has been developed in this program. The high power WW LED is an ideal source for use as replacement for incandescent, and Halogen reflector and general purpose lamps of similar lumen value. Over the two year period, we have made following accomplishments: developed a high power warm white LED product and made over 50% improvements in light output and efficacy. The new high power WW LED product is a die on ceramic surface mountable LED package. It has four 1x1 mm{sup 2} InGaN pump dice flip chip attached to a ceramic submount in 2x2 array, covered by warm white phosphor ceramic platelets called Lumiramic⢠and an overmolded silicone lens encapsulating the LED array. The performance goal was achieved through breakthroughs in following key areas: (1) High efficiency pump LED development through pump LED active region design and epi growth quality improvement (funded by internal programs). (2) Increase in injection efficiency (IE) represented by reduction in forward voltage (V{sub f}) through the improvement of the silver-based p-contact and a reduction in spreading resistance. The …

2000 Census: Complete Costs of Coverage Evaluation Programs Are Not Available
A letter report issued by the General Accounting Office with an abstract that begins "To assess the quality of the population data collected in the 2000 Census, the U.S. Census Bureau conducted the Accuracy and Coverage Evaluation (A.C.E.) program, which focused on a survey of housing units designed to estimate the number of people missed, counted more than once, or otherwise improperly counted in the census. GAO reviewed the life cycle costs of the A.C.E. program and its predecessor, the Integrated Coverage Measurement (ICM) program. GAO found that the original estimated cycle costs of conducting the ICM/A.C.E. programs were $400 million. The first evidence for the original $400 million estimate is in the original budget justifications for fiscal year 2000. The bureau based its estimates of ICM/A.C.E. costs on assumptions about the needs for personnel and benefits, contractual services, travel, office space, equipment, and other costs necessary to conduct and support operations of the programs. The budgeted amounts that GAO identified from bureau records for conducting the ICM/A.C.E. programs are $277 million through fiscal year 2003. The obligated costs that GAO identified from bureau records for conducting the ICM/A.C.E. programs are $207 million through fiscal year 2001. $58 million of …

2000 Census: Lessons Learned for Planning a More Cost-Effective 2010 Census
A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed the funding of 2000 Census planning and development efforts and the impact it had on census operations. Total funding for the 2000 Census, referred to as the life cycle cost, covers a 13-year period from fiscal year 1991 through fiscal year 2003 and is expected to total $6.5 billion adjusted to 2000 year dollars. This amount was almost double the reported life cycle cost of the 1990 Census of $3.3 billion adjusted to 2000 year dollars. Considering these escalating costs, the experience of the U.S. Census Bureau in preparing for the 2000 Census offers valuable insights for the planning and development efforts now occurring for the 2010 Census. Thorough and comprehensive planning and development efforts are crucial to the ultimate efficiency and success of any large, long-term project, particularly one with the scope, magnitude, and the deadlines of the U.S. decennial census. For fiscal years 1991 through 1997, $269 million was requested in the President's Budgets for 2000 Census planning and development and the program received funding of $224 million by Congress, or 83 percent of the amount requested. According to U.S. Census Bureau …
