Astro-navigation
If it were possible to determine the velocity of a vessel relative to the surface of the Earth, we would know its position at any instant by using the formulae of the previous section in all cases with a v con...

Some of the Instruments and Mathematics Used by the Navigator
This section is not meant to be a manual of elementary mathematics but is merely intended to show the reader how the formulae employed in the previous sections can be deduced by employing some of the concepts ...

Qualitative Description: The Relevant Astronomical Phenomena
As a consequence of being a gyroscope, the axis of rotation of the Earth slowly changes its position relative to the normal of the plane of the ecliptic.

Ephemerides
This low accuracy ephemeris is based on an algorithm for computing the GHA and of the Sun.

Terrestrial Navigation
In order on a , i.e., a curve on the globe that intersects all the meridians at the same angle C, it is desirable to construct a map/chart that provides an accurate one to one correspondence between the coo...

Methods for Reducing Measured Altitude to Apparent Altitude
In the previous chapters, exact mathematical methods have been provided always assuming that the parameters entering the calculations were correct.

Elements of Astronomy as Used in Navigation
In this section we shall develop some approximations for the most basic aspect of an ephemeris for the Sun and the stars which will enable the navigator to calculate approximations to the (GHA) and δ of th...

Quantitative Treatise of Those Phenomena
In order to derive explicit formulae for the effects of , , proper motion, aberration and annual parallax on (a-RA) and δ of the COs, it is convenient to refer to their changing positions on the .

Constructing backbone network by using tinker algorithm
Revealing how a biological network is organized to realize its function is one of the main topics in systems biology. The functional backbone network, defined as the primary structure of the biological network...

Equivariant Verlinde Formula from Fivebranes and Vortices
We study complex Chern–Simons theory on a Seifert manifold M 3 by embedding it into string theory. We show that complex Chern–Simons theory on M 3 is equivalent to ...

Circular Pentagons and Real Solutions of Painlevé VI Equations
We study real solutions of a class of Painlevé VI equations. To each such solution we associate a geometric object, a one-parametric family of circular pentagons. We describe an algorithm that permits to compu...

Strong Converse Exponent for Classical-Quantum Channel Coding
We determine the exact strong converse exponent of classical-quantum channel coding, for every rate above the Holevo capacity. Our form of the exponent is an exact analogue of Arimoto’s, given as a transform o...

On the Geometry of the Level Sets of Bounded Static Potentials
In this paper we present a new approach to the study of asymptotically flat static metrics arising in general relativity. In the case where the static potential is bounded, we introduce new quantities which ar...
