Universal Newborn Hearing Screening (UNHS) is an important tool for detecting hearing impairment in newborns, but it is often hindered by unacceptably long test times. This paper will describe a preliminary data set obtained from 100 newborns using a new form of automated auditory brainstem response (AABR): a non-linear maximum length sequence (MLS

This paper presents an approach to optimize the surface finish in end milling titanium-alloy of Ti-6AI-4V using uncoated WC-Co and PCD inserts under dry conditions. Response surface methodology is utilized to develop an efficient mathematical model for surface roughness in terms of cutting speed, feed and axial depth of cut. For this purpose, a num

In this Letter, we apply the homotopy-perturbation method (HPM) to obtain approximate analytical solutions of the time-dependent Emden– Fowler type equations. We also present a reliable new algorithm based on HPM to overcome the difficulty of the singular point at x = 0. The analysis is accompanied by some linear and nonlinear time-dependent sing

In this Letter, the homotopy-perturbation method (HPM) is employed to derive approximate series solutions of nonlinear population dynamics models. The nonlinear models considered are the multispecies Lotka–Volterra equations. The accuracy of this method is examined by comparison with the available exact and the fourth-order Runge–Kutta method (

In this Letter, solutions of a class of singular initial value problems (IVPs) in the second-order ordinary differential equations (ODEs) by homotopy-perturbation method (HPM) are presented. HPM yields solutions in convergent series forms with easily computable terms, and in some cases, yields exact solutions in one iteration. Comparisons with the

This paper presents an automatic sign language translator, which is able to translate Malaysian sign language using pattern-matching algorithm. The sign language translator is a vision-based system where the image of the sign is captured by a camera, processed and translated into English by the computer. This sign language translator is able to rec

This note examines the empirical validity of the monetary model of exchange rate determination for The Philippines via cointegration and vector error-correction model. It is found that the monetary model is a valid framework for the long-run exchange rate between Philippines peso-US Dollar exchange rate. However, the typical linear restrictions of

Introduction: Bone cyst is a rare benign bone tumour which normally affects the vertebral region or long bones. Despite its benign in nature, this lesion is expansile and may cause local compression and destruction of bone and soft tissues. Involvement of facial bones is very uncommon, and the lacrimal bone is very rare. Diagnosis usually achieved

Melioidosis that is caused by Burkholderia pseudomallei, is a significant public health problem in Southeast Asia and some other tropical countries. It involves many systems, especially the respiratory system. Melioidosis can mimic various common disease such as tuberculosis or tumor of the bones and joints. Mortality rates and relapse rate are hig

This paper reports new findings on the price effect from trading halts - both voluntary and mandatory - over 2000-2004 in an emerging share market, Malaysia. Based on our overall sample, trading halts lead to positive price reaction, increased volume, and increased volatility. We found evidence of information leakage resulting in a significant diff
