A dispute arose between Project Owner and Contractor over payment of the completed earthworks. The dispute was referred to arbitration on the volume of geomaterial had been excavated. Basically, it was an old issue on rock or no rock! The Contractor claimed the geomaterial is rock while the Project Owner claimed the geomaterial is not rock. A multidisciplinary geo-team, including engineering geologists, geotechnical engineers and GIS analysts was gathered to prepare the report. The approaches to the arbitration case used were the application of the total geological history, rock strength and SPT N-value to classify the ground while GIS was used to calculate the volume of geomaterial. The site-specific geological model is based on consideration of the regional and local geological and geomorphological history and of the current ground surface conditions. Results from boreholes were studied together with separate laboratory testing results of rock samples collected by the client during construction works. Extrapolation of rockhead was based on UCS ≥ 50 N60 (kPa). The volume calculation of rocks excavated was conducted using boreholes where rockhead had been identified together with as-built ground level (finish level). In this paper, the practical strategies involved in the total geology history approach as well as rock strength and SPT N-value are identified by describing its application for construction dispute.

Abd Rasid Mamat,Mohd Khalid Awang,Norkhairani Abdul Rawi,Mohd. Isa Awang,Mohd Fadzil Abdul Kadir 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.2

Many textures based image retrieval researchers use global texture features for representing and retrieval of images from an image database. However, this leads to misrepresentation of local information leading to the inefficient image retrieval performance. This paper presents an approach to overcome the problem. The approach focuses on extracting local Haralick’s texture feature based on a predetermined region using the color co-occurrence matrix method, the selection of the ‘significant’ Haralik’s texture features and evaluation of the performance of the combination of the ‘significant’ features. The proposed method which is an Average Analysis and a well known method, Principal Component Analysis were applied to obtain ‘significant’ features. In order to compare the performance, a series of experiments were carried out for both methods, which is the proposed Average Analysis and the Principal Component Analysis. Experiments were performed on a 1000 selected images from the Coral image database which were divided into ten categories. Based on the experimental results, it is interesting to note that for the combination ‘significant’ features obtained from the proposed Average Analysis showed better retrieval performance compared to the Principal Component Analysis for almost all categories. This finding has an important implication in deciding the correct combination of ‘significant’ features for certain image properties. It has shown that the proposed method is able to produce less computational processing time due to a reduced amount of processing involved. The result is also compared to the previous researches and has shown an increase of an average precision from 8.5% to 26%.

M. A. H. Rasid,Khadija Benkara,Vincent Lanfranchi 한국정밀공학회 2017 International Journal of Precision Engineering and Vol.18 No.11

The absence of high-cost rare-earth magnet on the rotor of Synchronous Reluctance machine makes it one of the best option for an actuator in applications with high ambient temperature. Combined with an optimized rotor structure, it can deliver good performance. In the early design phase of the machine, development cost reduction of prototyping and testing can be obtained by having a fast electro-mechanical model that can evaluate the machine’s essential performance: operating envelope, power factor and efficiency. Therefore this study proposes a fast analytical tool that evaluates the electro-mechanical performance of a given Syncrel machine. Experimental evaluations done on a prototype machine has proven the validity and robustness of the tool. The resulting tool is ready to be used for fast electro-mechanical performance evaluation of any Syncrel machine topology with any power supply and control variations.

Purpose: This study aims to develop a conceptual model and validate the model using a unified theory of acceptance and use of technology to determine the Determinants of Intention to Use the Islamic Payment Gateway System among the Millennial Generation in Malaysia via a Structural Model. Based on past research, the UTAUT hypothesises four variable constructs: performance expectancy, effort expectancy, social Influence, and facilitating factors. These characteristics are predictive of behavioural intent. In terms of the study, the author added a religiosity variable instead of the four recommended moderators. Design/methodology/approach: A total of 303 field tests have been obtained from Malaysian millennial citizens using Islamic Fintech. Before the data is analysed into exploratory factor analysis, preliminary analysis such as normality and multicollinearity test has been conducted. Findings: All constructs, which are performance expectancy, effort expectancy, social Influence, facilitating condition, and behavioural intention with religiosity as the moderating, have no factor reduction, but all constructs identified two components under exploratory factor analysis. Moreover, all construct KMO tests more than 0.50. All constructs met unidimensionality, validity, reliability, and model fitness in CFA. All the requirements for model fit in this study have been achieved. Research limitations/implications: This study has significant consequences, particularly for the existing payment gateway system, which is already entering every area of human lifestyle with the millennial generation being targeted as the native user. Originality/value: This study fills the apparent gap in the existing payment gateway system literature by assessing religiosity as moderating through exploratory factor analysis.

Torque Ripple Analysis of Synchronous Reluctance Motor with Diff erent Rotor Topologies for Application with Dimensional Constraint

M. A. H. Rasid,Vincent Lanfranchi,Alejandro Ospina,Khadija El Kadri Benkara 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.5

Synchronous reluctance machine (SynRM) is reemerging as a thermally robust and inexpensive actuator solution mainly due to the lack of permanent magnet. Added to that, the possibilities of having diff erent rotor topologies make it very versatile where further optimization is possible depending on the objective, be it cost, ease of fabrication, power output, or torque quality. In an application where the outer dimension of the motor is strictly limited, this paper compares quantitatively and qualitatively the torque ripple of three SynRM machines of the same stator dimension equipped with diff erent rotor topologies: segmented, tooth and fl ux barrier. Using an experimentally validated FE model, the torque ripple and the ripple’s harmonic content are compared at maximum load (stator current, I S = 50 A) and load angle ( β = π/ 4). The machine adopting the fl ux-barrier rotor was shown to have the best torque quality (41% ripple), followed by tooth rotor (78% ripple) and fi nally segmented rotor (105% ripple). The harmonic contents are also presented and analyzed

Thien Sang Lim,Rasid Mail,Mohd Rahimie Abd Karim,Zatul Karamah Abdul Baharul Ulum,Mazalan Mifli,Junainah Jaidi 사람과세계경영학회 2020 Global Business and Finance Review Vol.25 No.2

Purpose: Decision-making process about financial investment is complicated. Relying on modern financial theory to explain behaviours of individual investors is inadequate because it focuses on the objective risk as the determinant for making investment decisions under the assumption that individuals are rational. The current study, which was built from the financial, sociological and psychological perspectives, investigated the predictors of risk perception and determined the association of risk perception and attitude toward financial investment intention. This study served the purpose of unravelling the complexity of the financial investment decision-making process among individuals. Design/methodology/approach: The research framework was based on Perception Formation Model (PFM) with further support from the Theory of Planned Behaviour, decision making models under risk, and knowledge-attitudebehaviour model. Purposive-sampling method was adopted. The dataset, which consisted a total of 492 responses from income earners below the age of prime savings years were entered for analysis. Twelve hypotheses were tested using the Analysis of Moment Structures (AMOS) statistical software. Findings: Measurement-model assessment revealed the data fitted well to the research model Results from the structural-model assessment revealed subjective knowledge, peer influence, internet influence, and risk propensity had a significant relationship with favourable risk perception. Consistent with the PFM proposition, it was found favourable risk perception significantly related to higher intention toward financial investment. Research limitations/implications: The resultant outcomes strengthen the understanding of how financial investment decision is performed by individuals, which is crucial in the personal-finance industry, especially in promoting a long-term and meaningful client-advisor relationship. Interestingly, objective knowledge, which measured the actual level of financial knowledge was found to be insignificantly associated with risk perception and intention toward financial investment. As a sizeable financial literature posited financial knowledge has impact on decision-making process, future study could perhaps examine whether objective knowledge could contextually alter the relationship between predictors and the endogenous variable. Originality/value: The study has successfully identified several predictors for risk perception about financial investment and provided an empirical link for knowledge-perception-attitude-intention, thus, enriching the behavioural finance literature. The research model was robust as it was formulated based on the three major pillars of behavioral finance, namely: financial, sociological, and psychological perspectives.

Developing Engineering Geological Model from Resistivity (ERT) Surveys: Several Case Studies from Malaysia

( Farid Dali ),( Abd Rasid Jaapar ),( Zakaria Mohamad ),( Afiq Farhan Abdul Rahim ),( Mohamad Faruq Syahmi Md Aripin ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2

Electrical Resistivity survey has been commonly used to investigate the anomalies of subsurface ground condition. Tomographic Pseudo section model presents the different range of resistivity value, indicating variation of soil layers, occurrence of groundwater, boulders or fractured bedrock zones. The complexity of subsurface geomaterials profile due to structural geology and weathering leads to potential inaccuracies in intrepetation without substantial geological input. Therefore, engineering geological model generated from subsurface electrical resistivity survey, combined with borehole and field observation input is very important to present the subsurface condition of the area. Thirteen (13) electrical resistivity survey lines were set up established at three (3) sites located at Selangor (Site A), Kuala Lumpur (Site B) and Negeri Sembilan (Site C). The objectives of these investigations are: to investigate potential geohazards near residential areas (Site A), to investigate the existence of subsurface boulders/rocks fragments that will affect the design and cost of geotechnical construction (Site B) and to investigate the incidence of displacement of water tank that exceeds allowable movement due to ground movement. A reliable geological interpretation presented in form of engineering geological model was utilized by geotechnical engineers/decision makers to solve construction and geohazards issues. It helps to visualize or summarize the outcome of any geological investigation tools in simplest way especially to non-geologist.
