The use of simultaneous masking in speech enhancement has shown promise for a range of noise types. In this paper, a new speech enhancement algorithm based on a short-term temporal masking threshold to noise ratio (MNR) is presented. A novel functional model for forward masking based on three parameters is incorporated into a speech enhancement fra

This paper presents the vibration issue in micro end milling of of poly methyl methacrylate (PMMA) workpiece using integrated multi-process machine tools DT 110 (Mikrotools Inc., Singapore) with control parameter; spindle speed, feed rate and depth of cut. The vibration was measured using accelerometer (DYTRAN Instruments Inc., USA). The optimum so

The availability of inexpensive PC sound cards that can simultaneously play and record stereo digital audio files permits a single PC or laptop or netbook to function as both a signal generator and as a dual-channel recording digital oscilloscope. This paper presents how sound card with Matlab Data Acquisition Toolbox can be utilized for instrument

In this work, a simple mitigation technique for the effect of impulsive noise in Haar discrete wavelet transform (DWT) based OFDM systems is presented. Based on the analysis for a certain configuration of Haar DWT-OFDM, redundancy in the transmitted samples was found and exploited to mitigate the impulsive noise by replacing the corrupted samples.

Imam Shawkani is Muhammad b. Ali b. Muhammad b. Abdillah al-Shawkani al-Sanani (born 1760). He is called al-Shawkani because of his attribution to his birth place, Hijrah Shawkan a small town a day’s journey from Sana, Yemen. He is also known as al-Sanani as an attribution to Sana where he grew up, studied and held the position of Qadi al-qudat u

This study describes performance analysis of a robust system for road sign identification that incorporated two stages of different algorithms. The proposed algorithms consist of HSV color filtering and PCA techniques respectively in detection and recognition stages. The proposed algorithms are able to detect the three standard types of colored ima

We investigate an Ising model with two restricted competing interactions (nearest neighbors, and one-level neighbors) on the Cayley tree of order four. We derive a recurrent equation for the Cayley tree of order k. We found an analytic solution for the given interactions in the case of order 4. Our result of the critical curve shows the existence o

A Case Report on Gender Identity Disorder with Recurrent Depressive Disorder is presented. Individuals having this disorder often exhibit discomfort about their actual anatomic gender, and they may have wished to alter their bodies. Sex role-stereotypes adopted during childhood are the beliefs, characteristics and behaviors of individual cultures t

This paper discusses burr in microdrilling that affect forms and functions of parts. The effects of microdrillingparameters on burr length and width are identified. The experiment was conducted using Mikrotools DT110 machine with one millimetre diameter of HSS on copper workpiece. Burr heights in terms of burr length and burr width were measured by

Pakistan because of its geographical location became a front line state in the war against terror since the attack on the World Trade Centre on September 11, 2001. Pakistan decided to align with USA to combat the so-called fundamentalist and Islamic terrorist. Currently, the biggest threat to the state and citizens is the killing of innocent civili
