Performance of an automatic speech recognition (ASR) system tends to be dramatically degraded in the presence of impulsive noise. In the previous work [1], we proposed flooring the observation probability (FOP) to compensate the adverse effect of impulsive noise on sensitive dimensions of Mel-frequency cepstral coefficient (MFCC) features. Linear prediction cepstral coefficient (LPCC) is anothe...

There are various methods available for predicting impact sound pressure levels of floors. Understanding the accuracy of these prediction methods can be an important aspect of designing or refining a proposed flooring system. This paper provides a brief outline of some available prediction methods for massive (typically concrete) floors and light weight floor constructions. Consideration is giv...

A five year-old bull moose (Alces alces) was culled due to chronic hoof overgrowth that required frequent intervention. Radiographic examination revealed changes in phalangeal bone structure usually considered indicative for laminitis in domestic cattle; similar changes were absent in the hooves of a free-ranging moose of similar age. The captive animal had been maintained in exhibits whose flo...

The aim of this study is to investigate the static and dynamic behaviour multilayer materials manufactured from granular recycled rubber applied technical flooring. studied samples were by varying their thickness, density granulometry, as these are parameters that determine performance rubbery materials. Two mechanical tests, dynamic, carried out under controlled conditions evaluate means its m...

In this paper, a novel and noise robust front-end based on the combined application of spectral subtraction, spectral flooring and cumulative distribution mapping is proposed. Recognition experiments with the Aurora II connected digits reveal that the proposed front-end achieves an average digit accuracy of 81.46% for a model set trained from clean data and 89.54% for a model set trained from d...

We previously proposed a Mel-Wiener filter to enhance Mel-LPC spectra in presence of additive noise. The proposed filter was estimated based on minimization of sum of square error on the linear frequency scale and efficiently implemented in the autocorrelation domain without denoising input speech. In the previously proposed system we segregated speech and noise using an energy based VAD and a ...

An integrated solution is presented for the execution of building structures using timber-concrete composite (TCC) sections that make efficient use mechanical properties both materials. The system integrates flooring and shaped prefabricated beams composed a lower flange glued laminated timber (GLT) to one or more plywood veneer lumber (LVL) ribs linked an upper concrete slab poured in situ. pa...
