In the last years, an increasing interest of the market in devices able to integrate navigation and communication technologies has been noticed. Software Defined Radio technology helps in a tight integration of all possible radio signals into one, completely reconfigurable, universal device. In this work the problem of integration of Galileo, Satellite UMTS (S-UMTS) and IEEE 802.11b local wirel...

on a finsler manifold, we define conformal vector fields and their complete lifts and prove that incertain conditions they are homothetic.

A sub-/super-synchronous interaction (sub-/super-SCI) can occur between a voltage source converter-based high-voltage direct current (VSC-HVDC) and the permanent magnet synchronous generator (PMSG)-based wind farms with long AC transmission lines. However, influencing factors have not been properly analyzed. In this paper, these are deconstructed mathematically analyzed from detailed small-sign...

Hiring committees address the glut of highly qualified applicants for faculty positions by experimenting with new evaluation methods and adapting their expectations for today's increasingly competitive academic environment.

One of the factors which affects the gas lift performance is specific gravity of a lift gas (or the Molecular weight), which can influence the gas solubility in oil and has a direct effect on the gas lift performance. There are some previous researches which have included the lift gas specific gravity in their modeling, but in none of them, a comprehensive research about the effect of lift gas ...

In this paper, in order to study the relationship among different converters, a novel concept—modular high step-up converter—is proposed, which is composed of one basic converter, Nc cell (Nc-SUC), and M-source passive lossless clamped circuit (PLCC). means number capacitors represents PLCC. Nc-SUCs many voltage lift cells (VLCs) constant (CVLCs) are proposed their general gain formula deduced....
