Abstract: Identification systems play an important role in the field of security and control systems where the need to protect sensitive or privileged locations are a necessity. In recent times, the applications of biometrics are currently gaining grounds. The aim of this paper is to investigate the feasibility of an acoustics-based ear biometric system exploiting the reflective properties of the human ear canal as a Head Related Transfer Function (HRTF) suitable for real time recognition of individuals in dynamic environments. Using the dynamic simulations environment in MATLAB-SIMULINK real time data captures including enrolment and comparative similarity checks based on the.....

Abstract: A multi-layer multi-mode optical fiber of silica glass with differences in refractive indices between cladding layers is proposed. It is found that the amount of coupling between various modes will be minimized due to differences in the effective refractive indices among the adjacent modes. It will provide higher spectral efficiency at the time of signal transmission.

Abstract: Broadband data demand for various application is ever increasing. This has promoted the search for a technology, that will for its ubiquitous nature, provide this demand. Broadband over powerline is such technology. Because of its transmission medium (electrical power installation)broadband data suffers severe attenuation as they are propagated through it. In this paper, selective relaying and optimal power allocation are deployed in the broadband over powerline system to mitigate the attenuation. Three and five relays were deployed at different location between.......
