Investigating Negative Capacitance Shunt Circuit for Broadband Vibration Damping and Utilizing Aco for Optimization
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presents optimization of vibration damping for a rectangular thin plate using a single piezoelectric (PZT) patch shunted with negative capacitance, by utilizing the ant colony optimization (ACO) algorithm. The frequency range to be controlled is presented in the context of statistical energy analysis (SEA) where modal overlap factor (MOF

Genetic Diversity of the orange-Spotted Grouper (Epinephelus Coioides) in Terengganu Malaysia Based on Mitochondrial Cytochrome B Sequence Data
Research Output | Dar Al-hikmah Library | IIUM Only

Orange-spotted grouper (Epinephelus coioides) is known to be one of the economically high values marine. However, its spawning condition is still not well understood by the aqua culturist in Terengganu, Malaysia. Fish farmers depend on natural supply by col-lecting eggs of orange-spotted grouper from the wild. A study was conducted to deter-mine th

"i Bit you or I Beat You?" Acoustic Analysis of Vowel Contrast Produced by Malay Speakers
Research Output | Dar Al-hikmah Library | IIUM Only

This paper examines the acoustic properties of two pairs of English vowels: /i:/, /ɪ/ and /u:/,/ʊ/ produced by two sets of Malay speakers. This study was motivated by claims that Malaysian English (MalE) speakers do not distinguish these vowels’ phonemic lengths. The data was obtained from the recordings of five Malay informants. The recordings

Flowfield Dependent Variation Method for One Dimensional Stationary and Moving Boundary Problems
Research Output | Dar Al-hikmah Library | IIUM Only

Abstract: Complex fluid problems arise during fluid-structure interactions and pose a major challenge in the development of a stable generic numerical approach. Owing to the robustness of flowfield dependent variation (FDV) method in dealing with complex flow interactions, a new numerical procedure using the FDV method coupled with arbitrary Lagran

Isolation and Detection of Biosurfactant Producing Bacteria from Palm Kernal Cake (Pkc)
Research Output | Dar Al-hikmah Library | IIUM Only

The present research study was aimed to isolate and detect for biosurfactant producing microorganisms from Palm Kernal Cake (PKC). Seven bacteria were isolated from PKC and labelled as SV1, SV2, SV3, SV4, SV5, SV6 and SV7. It was found that almost all the bacteria are potential biosurfactant producers as they were positive for most of the detection

Scattering of a two-Soliton Molecule by Gaussian Potentials in Dipolar Bose–einstein Condensates
Research Output | Dar Al-hikmah Library | IIUM Only

Two bright solitons in a dipolar Bose–Einstein condensate (BEC) can form stable bound states, known as soliton molecules. In this paper we study the scattering of a two-soliton molecule by external potential, using the simplest and analytically tractable Gaussian potential barriers and wells, in one spatial dimension. Collisions of soliton molecu

Status of Heavy Metals in Surface Sediments of the Western Part of the Johor Straits Using a Sediment Quality Guideline
Research Output | Dar Al-hikmah Library | IIUM Only

Cu, Zn, Ni and Pb concentrations in surface sediments collected from 10 stations in the western part of the Johor Straits were determined. Samples were acid digested and metal concentrations were determined by atomic absorption spectrometry (AAS). The obtained results showed that Zn had the highest concentration (111.7±78.8 g/g) among the selected

Scattering of a two-Soliton Molecule by Gaussian Potential Barriers and Wells
Research Output | Dar Al-hikmah Library | IIUM Only

Two anti-phase bright solitons in a dipolar Bose-Einstein condensate can form stable bound states, known as soliton molecules. In this paper we study the scattering of a twosoliton molecule by external potential, using the simplest and analytically tractable Gaussian potential barriers and wells, in one spatial dimension. Theoretical model is based

Soliton Scattering on the External Potential in Weakly Nonlocal Nonlinear Media
Research Output | Dar Al-hikmah Library | IIUM Only

The Nonlinear Schrödinger Equation (NLSE) is one of the universal mathematical models and it arises in a such diverse areas as plasma physics, condensed matter physics, Bose - Einstein condensates, nonlinear optics, etc. In this work the scattering of the soliton of the generalized NLSE on the localized external potential has been studied, taking

Investigating Mat Rempit's Linguistic Identity: Assigning New Meanings to Standard Malay Words
Research Output | Dar Al-hikmah Library | IIUM Only

This study looks at the different sets of words used by the local Mat Rempit community in Malaysia to construct and signal their own unique subcultural identity. These sets of words are often borrowed from the standard Malay language. New meanings or senses have been assigned to these words as a result of this phenomenon. The Mat Rempit's lingu
