In theAlmagest, Ptolemy used some additional cycles to account for how the latitudes of planets change over time. In reality this happens because the planets don’t all move in the same plane. Ptolemy also used additional ‘epicyclets’ to account for peculiarities in the orbits of Mercury an...
This project looks to design a calculus that utilises the semantic structure of quasi-Borel spaces, introduced in ‘A convenient category for higher-order probability theory‘. Ohad and his team will develop the internal language of quasi-Borel spaces as a “semantic universe” for stochastic proc...
It involves only simple and directly measurable physical values. The different expressions of resolution are summarized in Table 15.1. TABLE 15.1.

Specifying the viewpoint in terms of azimuth and elevation is conceptually simple, but it has limitations. It does not allow you to specify the actual position of the viewpoint, just its direction, and thez-axis is always pointing up. It does not allow you to zoom in and out on the sc...
Define altazimuth. altazimuth synonyms, altazimuth pronunciation, altazimuth translation, English dictionary definition of altazimuth. n. 1. A mounting for astronomical telescopes that permits pointing adjustments in both altitude and azimuth. 2. A teles
Clearly, two terms are appeared in the second part of Eq. (7) as for some orientations the sun can rise and set on the surface twice throughout a day [54]. The signs of ωss and ωsr depend upon the surface orientation and would change as described by [33]: (8)|ωsr|=min[ω...

The main contribution of this paper is to propose a simple and feasible method to combine time–frequency parameters and the complex acoustic intensity method. The proposed method can estimate the azimuth of multiple LFM signals, which are separable in the time–frequency domain. In this method, ...
Since the proposed algorithm is actually performed in the frequency domain, it is relatively simple to use the CS algorithm. To summarize, the TSPT algorithm solves the sparse equation of (42) by LU decomposition for a given non-uniformly sampled multi-channel SAR signal b . Then, using the...
