Eclipse radius measurements

Methods for predicting the path edges and reducing observations of total solar eclipses for determining variations of the solar radius are described. Analyzed observations of the 1925 January eclipse show a 0.7 (arc second) decrease in the solar radius during the past fifty years

Mathematical specifications of the Onboard Navigation Package (ONPAC) simulator (revision 1)

The mathematical theory of the computational algorithms employed in the onboard navigation package system is described. This system, which simulates an onboard navigation processor, was developed to aid in the design and evaluation of onboard navigation software. The mathematical formulations presented include the factorized UDU(T) form of the extended Kalman filter, the equations of motion of the user satellite, the user clock equations, the observation equations and their partial derivatives, the coodinate transformations, and the matrix decomposition algorithms

Culture and Gender : A Look at Japan and New Zealand

American society at large has, in turn, taken hold of a ""feminism"" that assumes American cultural superiority, using the terms of feminist critique to assert the backwardness, the unworthiness, and the hopelessness of the non-white world. (Juliette Guilbert, 1998,p. 12

Revealing The Millimeter Environment of the New FU Orionis Candidate HBC722 with the Submillimeter Array

We present 230 GHz Submillimeter Array continuum and molecular line observations of the newly discovered FUor candidate HBC722. We report the detection of seven 1.3 mm continuum sources in the vicinity of HBC722, none of which correspond to HBC722 itself. We compile infrared and submillimeter continuum photometry of each source from previous studies and conclude that three are Class 0 embedded protostars, one is a Class I embedded protostar, one is a Class I/II transition object, and two are either starless cores or very young, very low luminosity protostars or first hydrostatic cores. We detect a northwest-southeast outflow, consistent with the previous detection of such an outflow in low-resolution, single-dish observations, and note that its axis may be precessing. We show that this outflow is centered on and driven by one of the nearby Class 0 sources rather than HBC722, and find no conclusive evidence that HBC722 itself is driving an outflow. The non-detection of HBC722 in the 1.3 mm continuum observations suggests an upper limit of 0.02 solar masses for the mass of the circumstellar disk. This limit is consistent with typical T Tauri disks and with a disk that provides sufficient mass to power the burst.Comment: 12 pages, 7 figures, accepted by Ap

Effect of solidity and inclination on propeller-nacelle force coefficients

A series of wind tunnel experiments were conducted to study the effect of propeller solidity and thrust axis inclination on the propeller normal force coefficient. Experiments were conducted in the Langley 14 by 22 foot Subsonic Tunnel with a sting mounted, counterrotation, scale model propeller and nacelle. Configurations had two rows of blades with combinations of 4 and 8 blades per hub. The solidity was varied by changing the number of blades on both rows. Tests were conducted for blade pitch setting of 31.34 deg, 36.34 deg, and 41.34 deg over a range of angle of attack from -10 deg to 90 deg and range of advance ratio from 0.8 to 1.4. The increase in propeller normal force with angle of attack is greater for propellers with higher solidity

A Pedagogical Study of Tone Neutralization in Cibemba Phonetics and Phonology

The paper discussed the concept of tone in African languages generally and in the Bantu linguistic group in particular from a pedagogical perspective. Using illustrative examples from Cibemba, the major language of Zambia, with an air of extension in DR Congo, in comparison with Germanic and Romance languages, the paper pointed out various theoretical issues surrounding tone. Amongst issues discussed was the need to put tone in context as opposed to approaching tone purely from the perspective of lexical semantics or content. This view of tone generally defined as syllable-based relative pitch contrast effectively and separates segmental units from suprasegmental units in order to satisfy pedagogical needs. For instance, the French text remains recognizable regardless of whether or not accents are omitted, thanks to context. Similarly, the French dictation exercise stands to benefit from using isolated vocabulary words in addition to narratives or passages that put text in context. The issue of tone context also raises the question of definition of phonetics and how it differs from phonology. Last but not least the paper argued that tone patterns represent dialect variations and their evolution to the extent that diachronic and synchronic tests can be administered
