MEMS ̄ow sensors for nano- ̄uidic applications

This paper presents micromachined thermal sensors for measuring liquid ̄ow rates in the nanoliter-per-minute range. The sensors use a boron-doped polysilicon thin-®lm heater that is embedded in the silicon nitride wall of a microchannel. The boron doping is chosen to increase the heater's temperature coef®cient of resistance within tolerable noise limits, and the microchannel is suspended from ...

Recent Advancements in Speech Enhancement

Speech enhancement is a long standing problem with numerous applications ranging from hearing aids, to coding and automatic recognition of speech signals. In this survey paper we focus on enhancement from a single microphone, and assume that the noise is additive and statistically independent of the signal. We present the principles that guide researchers working in this area, and provide a det...

SPLINE COLLOCATION FOR NONLINEAR FREDHOLM INTEGRAL EQUATIONS

The collocation method based on cubic B-spline, is developed to approximate the solution of second kind nonlinear Fredholm integral equations. First of all, we collocate the solution by B-spline collocation method then the Newton-Cotes formula use to approximate the integrand. Convergence analysis has been investigated and proved that the quadrature rule is third order convergent. The presented...

Recent Advancements of Treatment for Leptomeningeal Carcinomatosis

Treatment of Leptomeningeal carcinomatosis (LMC) from solid cancers has not advanced noticeably since the introduction of intra-cerebrospinal fluid (CSF) chemotherapy in the 1970's. The marginal survival benefit and difficulty of intrathecal chemotherapy injection has hindered its wide spread use. Even after the introduction of intraventricular chemotherapy with Ommaya reservoir, frequent devel...
