A synchronous polarimeter was set up for the measurement of small rotation angles of the polarization plane of light. The polarimeter is based on a polarizer–Faraday modulator–analyzer structure with a synchronous detection ...

This report is a review of Darwin`s classical theory of bodily tides in which we present the analytical expressions for the orbital and rotational evolution of the bodies and for the energy dissipation rates due to their ...

Context. Most massive stars are in binary or multiple systems. Several massive stars have been detected as double-lined spectroscopic binaries and among these, the OWN Survey has detected a non-negligible number whose ...

In this contribution we present the mutual synchronization of an ensemble of robots with strictly different architecture. The main idea is to achieve synchronization in an group of robots composed by rotational-rotational ...

We have measured the rotational velocities (v sin i) of the mass donors in a number of D'-type symbiotic stars (SSs), using the cross-correlation function method. Four out of five D' SSs with known v sin i appeared to be ...

Stellar rotation is an important parameter to be considered in the study of stellar evolution and structure, as it relates to several equally relevant parameters such as mass and temperature and influences the chemical ...

This master thesis presents the development of a control system to vertical axis wind turbine in order to harnessing its maximum performance. Vertical axis turbine designs and how they could be integrated with urban area ...
