A significant amount of speech is typically required for speaker verification system development and evaluation, especially in the presence of large intersession variability. This paper introduces a source and utterance-duration normalized linear discriminant analysis (SUN-LDA) approaches to compensate session variability in short-utterance i-vector speaker verification systems. Two variations ...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...
Self-organized criticality describes a class of dynamical systems that maintain themselves in an attractor state with no intrinsic length or time scale. Fundamentally, this theoretical construct requires mechanism for instability may trigger additional instabilities locally via dissipative processes. This concept has been invoked to explain nonlinear phenomena such as featureless energy spectra...
The small sizes of low mass stars in principle provide an opportunity to find Earth-like planets and “super Earths” in habitable zones via transits. Large area synoptic surveys like PanSTARRS and LSST will observe large numbers of low mass stars, albeit with widely spaced (sparse) time sampling relative to the planets’ periods and transit durations. We present simple analytical equations that c...
Recently, consumers have become more concerned with foods contain natural ingredients in terms of health and economic. Hence, in this study the effect of concentrate of smoked and sun dried raisin at 3 levels (1, 3 and 5%) as a natural humectant to improve the quality and shelf life of flat bread were investigated. Results showed that addition of smoked and sun dried raisin improved quality and...
Aerosols are tiny liquid or solid particles suspended in the air have a strong influence on air quality, human health and climate change. Sun-photometer is a tool for measuring the optical and physical characteristics of aerosols by using sunlight at various wavelengths from the Earth surface. In this paper, the design, construction, and calibration of a single channel sun-photometer is present...
TESS Discovery of a Super-Earth and Three Sub-Neptunes Hosted by the Bright, Sun-like Star HD 108236
We report the discovery and validation of four extrasolar planets hosted by nearby, bright, Sun-like (G3V) star HD~108236 using data from Transiting Exoplanet Survey Satellite (TESS). present transit photometry, reconnaissance precise Doppler spectroscopy as well high-resolution imaging, to validate planetary nature objects transiting HD~108236, also known TESS Object Interest (TOI) 1233. The i...
HD 191939 (TOI-1339) is a nearby ( d = 54 pc), bright V 9 mag), and inactive Sun-like star (G9 V) known to host multi-planet transiting system. Ground-based spectroscopic observations confirmed the planetary nature of three sub-Neptunes (HD b, c, d) originally detected by TESS were used measure masses for planets b c with 3σ precision. These previous also reported discovery an additional Saturn...
