The study proposes an improved feature extraction method that is called Wavelet Cepstral Coefficients (WCC). In traditional cepstral analysis, the cepstrums are calculated with the use of the Discrete Fourier Transform (DFT). Owing to the fact that the DFT calculation assumes signal stationary between frames which in practice is not quite true, the

لقد اختلفت استجابة الطلبة من شخص إلى آخر بسبب خلفيتهم في تعلم اللغة العربية. وذلك يبدو واضحاً في معظم الجامعات خاصة الذين يدرسون في مستوى المبتدئ. ومن الجدير بالذكر، أن تأثر الطلبة الناطقين بغ�

High friction and low wear are the prime functional properties of a brake pad material. Therefore main ingredients of brake pad materials are filler or reinforcement material, binder, friction modifiers, abrasive material and solid lubricant. There is a growing tendency to replace the asbestos filler in brake friction materials. Therefore, this pap

We earlier reported proteomic profiles indicating VDAC2 as a potential biomarker for over-stunned zchicken. The current work focused on cloning VDAC2 gene from chicken’s skeletal muscle into Escherichia coli. R A from chicken’s skeletal muscle was isolated and purified to synthesize the cDNA. After DNA amplification by proofread DNA polymerase,

This study is part of ongoing educational research conducted by the Department of Conservative Dentistry, University of Malaya, Malaysia, to evaluate the perception of clinical pairing. A thirteen-question survey was distributed to 148 dental students after they had experienced four-handed dentistry. The objectives were to identify the advantages,

Hibiscus sabdariffa (local name Roselle) is usually used as a beverage in Southeast Asia. It has been shown that this plant has benefits to the health in term of improving diabetes and hiperlipidemia conditions. In this study, the effect of H. sabdariffa aqueous extracts in preventing acute liver injury progression in rats induced by acetaminophen

When indulging in any piece of literature, one generally experiences the emotions contained in that piece. While this rings true for a reader reading a piece in their first language, users of a second language claim to be less emotional in their second language generally and especially whilst reading literature. This study therefore embarks on inve

In this research, composites containing 10-50 vol% SiC whiskers reinforced Cu matrix were fabricated using powder metallurgy technique. The mixtures were blended in a ball milling machine with the addition of ethanol for 2 hours at 150 rpm. The mixtures were allowed to dry in an oven at temperature of 40 °C. Then, the mixtures were uniaxially comp

Streptococcus pneumoniae is an important cause of human infections, particularly pneumonia, acute otitis media and meningitis. Hyaluronate lyase, an enzyme secreted by Streptococcus pneumoniae facilitates bacterial invasion by degradation of host connective tissue. This study was conducted to characterize the nucleotide sequence of hyaluronate lyas

Cryogenic cooling is an environmental friendly and effective cooling technology. The present work investigates the role of cryogenic cooling on tool wear at various cutting conditions. An indigenous method of applying cryogenic coolant was developed. Different methods of circulating the liquid nitrogen and vaporizing it inside the tool holder were
