IMPROVED MEMBRANE FILTER TECHNIQUE FOR RAPID IDENTIFICATION OF SPOILAGE ORGANISMS

An improved partial Haar dual adaptive filter for rapid identification of a sparse echo channel

Recently, a coupled echo canceller was proposed that uses two short adaptive filters for sparse echo cancellation. The first filter operates in the partial Haar domain and is used to locate the channel’s dispersive region; the second filter is then centered around this location to cancel the echo in the time domain. In this paper, we propose feasible solutions to improve the performance of this...

Membrane filter technique for the isolation of Yersinia enterocolitica.

A membrane filter procedure was developed for the isolation of Yersinia enterocolitica from aquatic environments. Primary differentiation was based on the fermentation of sorbitol, the absence of lysine decarboxylase and arginine decarboxylase-dihydrolase activities, and the production of urease. Sodium deoxycholate was incorporated as an inhibitor of background organisms. The presumptive ident...

A membrane-filter technique for the detection of complementary DNA.

An Improved Design Technique for Multichannel Non-Uniform Filter Bank

The present work proposed a simple efficient iterative technique for the design of non-uniform filter banks (NUFB). Here the prototype filters is designed using a constrained equiripple finite impulse response (FIR) technique in which instead of optimizing the cut-off frequency, the passband edge frequency (ωP) is varied iteratively in order to adjust the filter coefficients so that the reconst...

Rapid MALDI-TOF mass spectrometry identification of Leptospira organisms.

Leptospirosis is a worldwide deadly zoonotic disease. Accurate identification of the causative Leptospira spp. spirochetes ascertains the pathogenic status of the isolates, identifies potential source of infection and recognises outbreaks. Species identification is currently based on technically demanding, time and resources consuming serological and molecular methods. Matrix-assisted laser des...
