Each Apache configuration directive is described using a common format that looks like this: . ... This indicates the format of the directive as it would appear in a configuration file. This syntax is extremely directive-specific, and is described in detail in the directive's definition. ... If the directive has a default value ( i.e. , if you omit it from your configuration entirely, the Apache Web server will behave as though you set it to a particular value), it is described here. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

... Research Statement Summary The Lambek calculus was introduced in 1958 for linguistic purposes, but it enjoys a very natural algebraic interpretation. ... On this powerset one can naturally define three operations--multiplication, left and right division. ... Subsets of the free semigroup are naturally called formal languages. ... For the original Lambek calculus, the languages generated by these grammars are exactly context-free languages (M. Pentus 1992). ...

This server contains this site plus those listed at Astronomy Net . ... This site - www.astronomy.net - by itself sends about six billion bytes of information to visitors every month. ... I count on donations from patrons to help me keep Astronomy Net on the internet servicing the astronomy community. ...

... sin f = y / r . cos f = x / r . ... They are now viewed as new definitions of the sine and cosine, for the polar angle f given by x and y ( a slightly different way of formulating this definition is described further below ). ... sin 2 f + cos 2 f = 1 . ... Angle . ... Many trigonometry texts define the sine and cosine slightly differently, using the so-called unit circle . ... Then the distance AB ("the sine line") equals sin a , and the distance OA ("the cosine line") equals cos a . ...

... STScI has undertaken a project to place all HST keyword information in one source, the keyword database, and to provide a mecha­ nism for making this keyword information accessible to all HST users, the keyword dictionary, which is a WWW interface to the keyword database. ... Along with form­ ing the headers for the science data, most keyword values are ingested into HST archive catalog fields where they are accessible for archive searches and data characterization. ...

... Belts . ... Speed of motion is " kinetic energy ", like the energy of a turning flywheel or of the wind hitting a windmill, both of which can move machinery. ... As the hot gas of the corona--a plasma, really--expands upwards, its heat is converted to the kinetic energy of a fast flow, streaming outwards: the solar wind . Four or five days after leaving the Sun, solar wind plasma hits the magnetosphere, an obstacle in its path. ... How is solar wind energy transmitted to the magnetosphere? ...

... The perceptron structure, on the basis of which the database is built, is defined by a number of the input and output parameters and a required accuracy. ... The output perceptron data are the expansion coefficients of the scattering matrix elements in series of the generalized spherical functions. ... As the cluster structure depends on the generation conditions the expansion coefficients were averaged over 5--7 realizations of the clusters (for N . ... is the coefficient number. ...

... The VSOP Survey Continuum Source List . The radio sample for the VSOP continuum survey was defined to include all extragalactic radio sources with: . a total flux density at 5 GHz, S>=1.0 Jy . ... The sample also included all sources in the sky with a 5 GHz flux density S>5 Jy, regardless of spectral index and galactic latitude. ... The source would then be included in the VSOP sample (three of the sources were found with a flux density above 1 Jy and added to the sample). ...

... Course Content and Philosophy: . This course is designed to be an exploration of the process by which the Universe grows to a state of self-awareness, as defined by the emergence of intelligence which asks questions and seeks information about that very Universe. More specifically, it is a study in the evolution of ideas, based on observations, and the development of a non-unique evolutionary model that describes the origin of the Universe and the development of life. ...
