October 29, 2014 11:19 BC: 9404 Intro to Comp Maths 2nd Ed. Yang-Comp-Maths2014 page v Preface Computational mathematics is essentially the foundation of modern scien ti c computing. Traditional ways of doing sciences consist of two major paradigms: by theory and by experiment. With the steady increase in computer power, there emerges a third paradigm of doing sciences: by computer simulation. Numerical algorithms are the very essence of any computer simulation, and computationa...

True False 2 A​ny location on the Moon is sunlit for three weeks and is in darkness for one week as the Moon rotates. True False 3 I​n most months, there are no eclipses. True False 4 A​s the illuminated part of the Moon grows larger from new to full, it is said to "wane". True False 5 O​ur calendar divides the year into 30­day periods in recognition...

1. Introduction Target identifications/tracking, management of air traffic, and remote sensing are all common uses of ECG [1, 2] where transmitters send signal bursts and receivers receive dispersed versions of those signals. e scattering of signals is measured using TDEs and Doppler shifts in received signals, and the target’s range and radial velocities are computed. ese measurements are employed as measurements in ECG [3]. e fundamental concept of radars is similar to that of ...
