Bi-polar Supernova Explosions
We discuss the optical spectropolarimetry of several core-collapse supernovae, SN 1996cb (Type IIB), SN 1997X (Type Ic), and SN 1998S (Type IIn). The data show polarization evolution of several spectral features at levels from 0.5% to above 4%. The observed line polarization is intrinsic to the supernovae and not of interstellar origin. These data suggest that the the distribution of ejected ma...
متن کاملBi-3 C2 polar subdivision
Popular subdivision algorithms like Catmull-Clark and Loop are C almost everywhere, but suffer from shape artifacts and reduced smoothness exactly near the so-called “extraordinary vertices” that motivate their use. Subdivision theory explains that inherently, for standard stationary subdivision algorithms, curvature-continuity and the ability to model all quadratic shapes requires a degree of ...
متن کاملChapter 5 Bi - polar Junction Transistor
5.1. BJT Fundamentals. In this section we discuss the main principles behind the operation of the BJT. The NPN bipolar transistor consists of 2 NP-PN junctions, as depicted in Fig. 5.1.a. The bipolar device is composed of two diodes back to back with different doping profiles; the BJT has 3 terminals labeled as E(Emitter), B(Base) and C(Collector). The emitter is the most doped terminal and emi...
متن کاملOn the polar derivative of a polynomial
For a polynomial p(z) of degree n, having all zeros in |z|< k, k< 1, Dewan et al [K. K. Dewan, N. Singh and A. Mir, Extension of some polynomial inequalities to the polar derivative, J. Math. Anal. Appl. 352 (2009) 807-815] obtained inequality between the polar derivative of p(z) and maximum modulus of p(z). In this paper we improve and extend the above inequality. Our result generalizes certai...
متن کاملUni-polar Orthogonal Codes : Design, Analysis and Applications
The uni-polar orthogonal codes, with code length 'n' and code weight 'w' having auto-correlation and cross-correlation constraints equal to 1, can be designed with proposed algorithm. This proposed scheme design all the possible groups containing maximum number of orthogonal codes as per Johnson bounds. In this case, each of the designed groups is independent with other groups of uni-polar orth...
