In this chapter we first present a review of the methods for the tomographie reconstruction of a compact homogeneous object that lies in a homogeneous background. Then we focus on contour estimation and polyhedral shape reconstructions. We give some sufficient conditions to obain exact reconstructions from a complete set of projections in the 2.1) case

Multi-objective compact differential evolution
2014 IEEE Symposium on Differential Evolution (SDE), 2014A wide range of problems in engineering require the simultaneous optimization of several objectives. Given the nature of such problems, it is often the case that the optimization process needs to take place from a device with very limited resources. Compact algorithms are a suitable alternative for being implemented in devices with limited computing ...

Non-compact astronomical objects as microlenses
Astronomical & Astrophysical Transactions, 1997Abstract The microlensing of the distant stars by neutralino stars is considered. The neutralino sars have been considered in the recent paper of Gurevich and Zybin; moreover, it has been suggested that the stars should be regard as a major component of dark matter.

Gravitational waves from compact objects
Research in Astronomy and Astrophysics, 2010Large ground-based laser beam interferometers are presently in operation both in the USA (LIGO) and in Europe (VIRGO) and potential sources that might be detected by these instruments are revisited. The present generation of detectors does not have a sensitivity high enough to probe a significant volume of the universe and, consequently, predicted ...
