a cochlear implant is an implanted electronic device used to provide a sensation of hearing to a person who is hard of hearing. the cochlear implant is often referred to as a bionic ear. this paper presents an undecimated wavelet‑based speech coding strategy for cochlear implants, which gives a novel speech processor. the undecimated wavelet packet transform (uwpt) is computed like the wavelet ...

no on-site sanitation system treats both urine and faecal matter in one process. a laboratory scale biological filter was fed with high concentration of urea (4 g n/l) and 17.1 g cod/l to determine if it will be possible to treat liquid that leach from a ventilated improved pit latrine. the hlr in the proposed biological filter system was calculated to be ca 36 l/m2/d, significantly lower than ...

A humongous development in the study of Nyquist filter has been observed in the recent years. This paper presents a review of the work done on a Nyquist filter in the last decade. Nyquist filter is called M th band filter because it has zero coeffient at every M th sample except its middle coefficient. Different filter methods have been proposed with the focus of improving filter parameters lik...

This paper presents an area efficient architecture for a linear periodically time varying (LPTV) filter. It is developed from the output switching representation of LPTV filter. In this representation, an N-tap,M Period LPTV filter can be realized by M linear time invariant (LTI) filters of N taps each connected in parallel with an M periodic switch at the output. We devloped an area efficient ...

We consider properties of residuated lattices with universal quantifier and show that, for a residuated lattice $X$, $(X, forall)$ is a residuated lattice with a quantifier if and only if there is an $m$-relatively complete substructure of $X$. We also show that, for a strong residuated lattice $X$, $bigcap {P_{lambda} ,|,P_{lambda} {rm is an} m{rm -filter} } = {1}$ and hence that any strong re...

In this correspondence, we generalize the theory of compactly supported biorthogonal two-channel wavelet bases to M -channel. A sufficient condition for the M -channel perfect reconstruction filter banks to constructM -channel biorthogonal bases of compactly supported wavelets is derived. It is shown that the construction of biorthogonal M -channel wavelet bases is equivalent to the design of a...

We consider a problem for storing a map that associates a key with a set of values. To store n values from the universe of size m, it requires log2 ( m n ) bits of space, which can be approximated as (1.44 + n) log2 m/n bits when n ≪ m. If we allow ε fraction of errors in outputs, we can store it with roughly n log2 1 ε bits, which matches the entropy bound. Bloom filter is a wellknown example ...

آلتراسوند یکی از روش های تصویربرداری است که هیج ضرری برای بدن ندارد، بنابرین نسبت به سایر دستگاه های پزشکی از محبوبیت و کاربرد بیشتری برخوردار است. طراحی بورد front-end یکی از چالشهای بزرگ در طراحی دستگاه سونوگرافی است که در آن سیگنالهای مدوله شده از بدن با دامنه بسیار کم باز می گردند که می توانند در رنج فرکانسی 2 تا 12 مگاهرتز کار کنند. تکنولوژی روز سعی در کوچک کردن مدارهای الکترونیکی و کمینه ...
