Commercialization of Intellectual Property (IP) for Small and Medium Enterprisers (SMEs) in India

Lots of people in this modern era take the Intellectual property (IP) as a magical word and they think that the game can be understood only by the experts or the trained people. Even there is no surprise that you may be asking yourself that why and how IP is going to provide an emerging platform in Small and Medium Enterprises (SMEs) sector? Presently, the Small and Medium Enterprises (SMEs) in India are at a crossroad and there is an intense debate over the questions like what would be the future of these SMEs? How these SMEs can survive in the international trade arena? What role can the government play in making these SMEs more competitive? How can the Intellectual property (IP) generate wealth in the business? In order to know the answers of all these questions the paper is written and is concerned with the identification and analysis of current approaches of SMEs towards the Intellectual property (IP), the hurdles that they face; and the accessible & feasible solutions.Intellectual Property, Small and Medium Enterprisers, SMEs, Commercialization

Effect of guide field on three dimensional electron shear flow instabilities in collisionless magnetic reconnection

We examine the effect of an external guide field and current sheet thickness on the growth rates and nature of three dimensional unstable modes of an electron current sheet driven by electron shear flow. The growth rate of the fastest growing mode drops rapidly with current sheet thickness but increases slowly with the strength of the guide field. The fastest growing mode is tearing type only for thin current sheets (half thickness $\approx d_e$, where $d_e=c/\omega_{pe}$ is electron inertial length) and zero guide field. For finite guide field or thicker current sheets, fastest growing mode is non-tearing type. However growth rates of the fastest 2-D tearing mode and 3-D non-tearing mode are comparable for thin current sheets ($d_e <$half thickness $< 2\,d_e$) and small guide field (of the order of the asymptotic value of the component of magnetic field supporting electron current sheet). It is shown that the general mode resonance conditions for electron-magnetohydrodynamic (EMHD) and magnetohydrodynamic (MHD) tearing modes depend on the effective dissipation mechanism (electron inertia and resistivity in cases of EMHD and MHD, respectively). The usual tearing mode resonance condition ($\mathbf{k}.\mathbf{B}_0=0$, $\mathbf{k}$ is the wave vector and $\mathbf{B}_0$ is equilibrium magnetic field) can be recovered from the general resonance conditions in the limit of weak dissipation. Necessary conditions (relating current sheet thickness, strength of the guide field and wave numbers) for the existence of tearing mode are obtained from the general mode resonance conditions.Comment: The following article has been submitted to Physics of Plasmas.

Evolution of ultra-relativistic hollow-electron-beam wakefield drivers during their propagation in plasmas

Ultra-relativistic hollow electron beams can drive plasma wakefields ($\sim$ GV/m) suitable for positron acceleration. Stable propagation of hollow electron beams for long distances in plasmas is required to accelerate positrons to high energies by these plasma wakefields. In this work, we show by quasi-static kinetic simulations using the code WAKE that an ultra-relativistic azimuthally-symmetric hollow electron beam propagates in a plasma by developing fish-bone like structure and shifting its bulk, differentially along its length (rear part fastest), towards its axis due to the decrease in the betatron time period of beam electrons from the beam-front to beam-rear. Hollow electron beams with small radius collapse into their axis due to the pull by the secondary wakefields generated by some of the beam electrons reaching the axis. Hollow beams with sufficiently large radius, however, can propagate stably in plasmas for several meters and be used for positron acceleration.Comment: 8 figure

A family of well-behaved Karmarkar spacetime describing interior of relativistic stars

We are presenting a family of new exact solutions for relativistic anisotropic stellar objects by considering four dimensional spacetime embedded in five dimensional Pseudo Euclidean space known as Class I solutions. These solutions are well-behaved in all respects, satisfy all energy conditions and the resulting compactness parameter is also within Buchdahl limit. The well-behaved nature of the solutions for a particular star solely depends on index n. We have discussed the solutions in detail for the neutron star XTE J1739-285 (M = 1.51M$\odot$, R = 10.9 km). For this particular star, the solution is well behaved in all respects for $8 \le n \le 20$. However, the solutions with n < 8 possess increasing trend of sound speed and the solutions belong to n > 20 disobey causality condition. Further, the well-behaved nature of the solutions for PSR J0348+0432 (2.01M$\odot$, 11 km), EXO 1785-248 (1.3M$\odot$, 8.85 km) and Her X-1 (0.85M$\odot$, 8.1 km) are specified by the index n with limits $24 \le n \le 54$, $1.5 \le n \le 4$ and $0.8 \le n \le 2.7$ respectively.Comment: 8 pages, 17 figires, 1 tabl
