Introduction: One of the possible techniques to cope with the restrictions imposed by llow supply voltages is instantaneous companding [l], which is an inherent characteristic of translinear (TL) filters [2], also called exponential state-space filters [3]. TL filters exploit the exponential large-signal behaviour of the bipolar, or weak inversion MOS, transistor both for an expanding capacitan...

Recently, significant interest has been attracted by the potential use of aluminum nanostructures as plasmonic color filters to be great alternatives to the commercial color filters based on dye films or pigments. These color filters offer potential applications in LCDs, LEDs, color printing, CMOS image sensors, and multispectral imaging. However, engineering the optical characteristics of thes...

Polymorphisms. BamHI, EcoRI, and TaqI restriction fragment length polymorphisms at the bovine calpastatin locus. Source and Description of Probe. A 2.2-kb cDNA insert coding for Domains 2 through 4 plus a 3’ untranslated region of the bovine calpastatin gene was excised from the pBluescript vector (Stratagene, La Jolla, CA) with EcoRI and XhoI. Method of Detection. Nylon filters were prehybridi...

Blackwater or domestic waste is a type of liquid that requires adequate treatment so as not to pollute the environment. The effectiveness wastewater can be increased by using multilevel filters and aquatic plants remediation agents. This study aims improve quality communal (WWTP) reducing value parameters. used an plant agent, namely Roots Wangi (Vetiveria zizanoides). independent variables in ...

slow sand filters are as a proper technology for pre-treatment of raw water, with a fine and medium trubidity in small communities in developing countries. thus, with a minimum operation cost and minimum need for expest bodies have the maximum efficiency. the purpose of this research is carried out to evaluate the efficiency of two processes of horizontal flow roughing filter and vertical flow ...

The current work employs the HMC830 phase-locked loop chip to design a frequency synthesizer operating in L-band. can provide local oscillation signal for RF receiver front end. This article synthesis technique describe scheme. Due advantages of passive filters, such as simplicity, low cost, and phase noise, fourth-order RLC filter is proposed improve output quality reduce noise. performance th...

In this paper, an -convergence theory of filters in an L -space is established. By means of the -convergence theory, some important characterizations with respective to the closed sets, T2 separation and (

In this paper, Gaussian and elliptic high pass filters are analyzed for image sharpening qualitatively and quantatively . The filters are implemented in frequency domain using matlab software. Experiments are performed to compare the performance of both the filters ,processed images are presented. The results demonstrate that elliptic yields better results.
