We investigate the relationships between various sum of squares (SOS) and semidefinite programming (SDP) relaxations for the sensor network localization problem. In particular, we show that Biswas and Ye’s SDP relaxation is equivalent to the degree one SOS relaxation of Kim et al. We also show that Nie’s sparse-SOS relaxation is stronger than the edge-based semidefinite programming (ESDP) relax...

This paper follows the methodology introduced by Agrawal and Biswas in [AB92], based on a notion of universality for the relations associated with NP-complete problems. The purpose was to study NP-complete problems by examining the effects of reductions on the solution sets of the associated witnessing relations. This provided a useful criterion for NP-completeness while suggesting structural s...

Recently Biswas[1] extended Diffie-Hellman technique to generate multiple two-person-shared keys by exchange of two public keys. In this paper, we further generalize the Diffie-Hellman technique to generate multiple two-person-shared keys by exchange of any number of public keys and study its Polynomial Time Complexity, Security etc. Also, an upper bound for the number of shared keys in terms o...

The application of Fourier Transform (FT) spectroscopy instruments has broadened the knowledge and capabilities of textile researchers to study a host of projects including surface modifications of cotton fibers to impart flame retardant capabilities, monitoring aging effects on ancient cellulosic artifacts (Kavkler et al., 2011; Lojewski et al., 2010), determining the amount of dye fixation to...

Platynaspisflavoguttata (Gorham) (Coleoptera: Coccinellidae) is redescribed and the male genitalia are illustrated for the first time. It is also recorded from Sri Lanka for the first time. Platynaspisbimaculata (Hoang, 1983) is a new junior synonym of Platynaspisbimaculata Pang & Mao, 1979 (new synonym). Platynaspiskapuri Chakraborty & Biswas, 2000, the replacement name for Platynaspisbimacula...
