... You are worried that this light wing structure might not be strong enough to be safe. The article explains that an airplane can fly because the air exerts a force, called "lift," on the wings such that the lift is always perpendicular to the wing surface. ... To turn, the pilot "banks" the plane so that the wings are oriented at an angle to the horizontal. ... The article states that tests show that the new wing structure will support a force 4 times the lift necessary for level flight. ...

Pulkovo NEO Page . ... NEA Accuracy Estimation . ... The estimation of accuracy of the current CCD observations of asteroids and comets is constantly performed at Pulkovo Observatory. ... The (O-C) values, so called "Observed" minus "Calculated" positions, characterize numerically the observations of any observatory, both professional and amateur, during a short period (one or several close nights). ... So the (O-C) values for these objects nearly entirely define the errors of observations. ...

What is a Handler . ... mod_actions . ... A "handler" is an internal Apache representation of the action to be performed when a file is called. Generally, files have implicit handlers, based on the file type. Normally, all files are simply served by the server, but certain file types are "handled" separately. Apache 1.1 adds the ability to use handlers explicitly. ... The following directives will enable the send-as-is handler, which is used for files which contain their own HTTP headers. ...

In this talk I give an introduction to generalizations of the Riemann zeta function called "Weyl group multiple Dirichlet series". Weyl group multiple Dirichlet series are sums in several variables whose coefficients involve Gauss sums and also reflect the combinatorics of a given root system. ... These functions and their residues unify and generalize a number of examples which have been previously treated individually, often with applications to number theory. ...

fitcircle - find mean position and pole of best-fit great [or small] circle to points on a sphere. fitcircle [ xyfile ] -L norm [ -H [ nrec ] ] [ -S ] [ -V ] [ -: ] [ -bi [ s ][ n ] ] fitcircle reads lon,lat [or lat,lon] values from the first two columns on standard input [or xyfile ]. ... Then two locations are found: the mean of the input positions, and the pole to the great circle which best fits the input positions. ... If no file is specified, fitcircle will read from standard input. ...

... Sunspots are manifestations of magnetically disturbed conditions at the Sun 's visible surface. ... Sunspot appear often in groups, and the sunspot number R is defined as R = k ( f + 10 g ), where f is the total number of spots visible to the observer, g is the number of disturbed regions (single spots or groups of spots), and k is a constant for the observatory related to the sensitivity of the observing equipment. Sunspots display a clear 11-year cycle in their number and latitude. ...
