Abstract The development of a consistent framework for Calphad model sensitivity is necessary the rational reduction uncertainty via new models and experiments. In present work, theory was developed, closed‐form expression log‐likelihood gradient Hessian multi‐phase equilibrium measurement presented. inherent locality defined metric mitigated through use Monte Carlo averaging. A case study Cr–N...
We have determined silicon self-diffusivity at temperatures 735-875 degrees C based on the Raman shift of longitudinal optical phonon frequencies of diffusion annealed 28Si/30Si isotope superlattices. The activation enthalpy of 3.6 eV is obtained in such low temperature diffusion annealing. This value is significantly smaller than the previously reported 4.95 eV of the self-interstitial mechani...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
The advent of reconfigurable nodal elements, such as Optical Add/Drop Multiplexers (OADM) and CrossConnects (OXC) for Wavelength Division Multiplexed (WDM) networks, has led to a myriad of possible network architectures for the optical layer. In this paper we describe different architectures for resilient ring and mesh based WDM networks, and compare these architectures from a conceptual viewpo...
