Computational/experimental studies of isolated, single component droplet combustion

Isolated droplet combustion processes have been the subject of extensive experimental and theoretical investigations for nearly 40 years. The gross features of droplet burning are qualitatively embodied by simple theories and are relatively well understood. However, there remain significant aspects of droplet burning, particularly its dynamics, for which additional basic knowledge is needed for thorough interpretations and quantitative explanations of transient phenomena. Spherically-symmetric droplet combustion, which can only be approximated under conditions of both low Reynolds and Grashof numbers, represents the simplest geometrical configuration in which to study the coupled chemical/transport processes inherent within non-premixed flames. The research summarized here, concerns recent results on isolated, single component, droplet combustion under microgravity conditions, a program pursued jointly with F.A. Williams of the University of California, San Diego. The overall program involves developing and applying experimental methods to study the burning of isolated, single component droplets, in various atmospheres, primarily at atmospheric pressure and below, in both drop towers and aboard space-based platforms such as the Space Shuttle or Space Station. Both computational methods and asymptotic methods, the latter pursued mainly at UCSD, are used in developing the experimental test matrix, in analyzing results, and for extending theoretical understanding. Methanol, and the normal alkanes, n-heptane, and n-decane, have been selected as test fuels to study time-dependent droplet burning phenomena. The following sections summarizes the Princeton efforts on this program, describe work in progress, and briefly delineate future research directions

Studies of Birds and Mammals in the Baird and Schwatka Mountains, Alaska

In 1963 a joint University of Alaska-Smithsonian Institution crew worked at five locations in the Baird and Schwatka mountains in northwestern Alaska, conducting an ecological reconnaissance and faunal and floral inventory. Standard methods of observation and collection were used. Camps in the Kobuk drainage were located in the Redstone River valley and at Walker Lake, both on the margin of the taiga. The Noatak valley was represented by one camp each in the lower, middle, and upper reaches of the river, all in tundra. A summary of pre-1963 ornithological work in the region is presented. Significant records of distribution and/or breeding were obtained for the following birds: Podiceps grisegena, Anas platyrhynchos, Aythya valisineria, Histrionicus histrionicus, Melanitta perspicillata, Mergus merganser, Aphrizia virgata, Bartramia longicauda, Actitis macularia, Tringa flavipes, Phalaropus fuficarius, Lobipes lobatus, Larus hyperboreus,Xema sabini, Sayornis saya, Nuttalornis borealis, Eremophilia alpestris, Tachycineta thalassina, Riparia riparia, Petrochelidon pyrrhonota, Phylloscopus borealis, Dendroica petechia, Leucosticte tephrocotis, Zonotrichia atricapilla, Calcarius pictus; and the mammal, Spermophilus undulatus. Good series of Cletihrionomys rutilius (350) and Microtus miurus (147) have been deposited in the University of Alaska Museum. Severe doubt has been raised regarding the validity of the standard three-night trap grid for population estimation under wet conditions in arctic areas

A shipboard cable-hauling system for large electrical cables

An air -powered hauling machine and reeling device for use at sea with large electrical cable systems such as hydrophone arrays is described. The system may be used to haul cables from 0. 3 to 2 . 0 inch diameter. Hauling tensions up to 9 80 lbs . and speeds up to 4 30 ft/ min. are provided. The principal advantage of the system is that it does not cause the cable to bend while under tension. Reeling is accomplished under only sufficient tension to cause the cable to conform to the reel.Undersea Warfare Branch Office of Naval Research under Contracts Nonr-4029(00) NR 260-10

Dear Mother, I\u27ll Come Home Again

1. Oh! mother dear I sigh in vain, To live my childhood o\u27er again ... And see thy clear, love beaming eye ... Outshine the stars up in the sky, Oh mother dear bright sunny rays, That give such joy and heav\u27nly bliss, As by thy knee I used to pray, Or climb\u27d to steal affection\u27s kiss. CHORUS: Oh mother dear I sigh in vain To live my childhood o\u27er again, And see thy clear love beaming eye, Outshine the stars up in the sky. Oh! mother dear, Oh! my mother dear. 2. Oh! mother dear, those early scenes, The flow\u27ry fields, and meadows green, As thoughts come back I heave a sigh, And wish for happy days gone by; Long since I left my native shore, But now my heart beats just as then, Tho\u27 miles of sea between us roar, Dear mother I\u27ll come again

Long Run Neutrality of Money in Mexico

The Fisher-Seater (FS) methodology is used to investigate long run money neutrality with respect to real GDP and real output in ten selected industries in Mexico. Size distortions and low power of the FS test, issues first raised by Coe and Nason (2003, 2004), are addressed using the Coe-Nason bootstrapping procedure. The evidence indicates that long run money neutrality can be rejected for real GDP and for up to five of the ten industrial sectors studied. These findings indicate that the effects of monetary policy are likely to differ across sectors even in the long run.money neutrality, Fisher-Seater Test, bootstrapping.

Can the Fed Predict the State of the Economy?

Recent research has documented that the Federal Reserve produces systematic errors in forecasting inflation, real GDP growth, and the unemployment rate, even though these forecasts are unbiased. We show that these systematic errors reveal that the Fed is “surprised” by real and inflationary cycles. Using a modified Mincer-Zarnowitz regression, we show that the Fed knows the state of the economy for the current quarter, but cannot predict it one quarter ahead.Forecast Evaluation, Federal Reserve, Systematic Errors, Recessions
