LC sine-wave oscillators using general-purpose voltage operational-amplifiers
M. M. Jakas, F. Llopis
It has been found that some text-books show LC-oscillators that may not work as assumed. Thus, the typical example showing a LC-oscillator driven by a voltage operational-amplifier…
Curvature of (special) almost Hermitian manifolds
Francisco Martin Cabrera, Andrew Swann
We study the curvature of almost Hermitian manifolds and their special analogues via intrinsic torsion and representation theory. By deriving different forumlae for the skew-symmet…
Type Ia SN1999cw: photometric and spectroscopic study
F. Bufano, M. Turatto, S. Benetti +4
The preliminary analysis of the optical data of SN1999cw show that this object has the photometric and spectroscopic behavior of a Type Ia supernova similar to SN1991T, reaching an…
Riemann-Hilbert analysis for Jacobi polynomials orthogonal on a single contour
A. Martinez-Finkelshtein, R. Orive
Classical Jacobi polynomials , with , have a number of well-known properties, in particular the location of their zeros in the open interval . This…
