    This paper presents a numerical simulation of flow in a microchannel heat sink. The channel
    was defined as a dimension with less than 1.0milimeter and greater than 100.0micrometer. The ANSYS
    CFX 2015 was used to predict the flow in the microchannel. Besides, simulations were undertaken to
    determine the flow of the fluid within the microchannel in three different models. Therefore, three
    different models were employed for this study. The first model was a square-shaped channel with 0.5mm
    width and 0.5mm height constructed along 28.0mm channel length. The second and the third models
    were in rectangular shape. The differences between these models were their width and height of
    channel. The dimension for the second model was 0.75mm height and 0.5mm width (rectangular A),
    while the dimension for the third model was 0.5mm height and 0.75mm width (rectangular B). All the
    microchannel heat sink models had been simulated and showed results for pressure, temperature, and
    velocity inside the microchannel. The results were compared for each model and the data had been
    validated from published data. In addition, the initial velocity was set in a range between 0.1m/s and
    0.5m/s. The highest pressure drop was recorded for the square microchannel. It was 58.12% higher
    than the pressure drop found in the rectangular microchannel with 0.75mm width, while 0.02% closer
    with the 0.75mm-height rectangular microchannel. Furthermore, there was a 33.34% of temperature
    difference, which had been higher for the square microchannel. Nevertheless, the highest velocity of
    0.57m/s was recorded at the outlet of the microchannel. These had been consistent with other published
    data.

    Adolescents need more attention on eating habits as they go through a critical path
    period of physical, physiological and psychological changes from children to adult.
    Therefore, planning a proper healthy diet menu is important to adolescents to have
    the sufficient nutrients for proper growth. However, manually plan healthy diet menu
    is complicated, inefficient and time-consuming. The purpose of this study is to develop
    a mathematical model of healthy diet menu plan that minimizes the daily fat intake
    and meets the necessary nutrient intake for adolescents aged 13 between 17 years old
    within the budget provided by Majlis Amanah Rakyat (MARA) for Malaysia adolescent
    in MARA Junior Science College (MJSC) boarding schools. Optimization approach and
    binary integer programming method were used to address the diet problem in this
    study. The finding of the study indicates that the developed mathematical model of
    healthy diet menu plan for MJSC can generate menu plan that minimizes the total fat
    intake at minimum level of requirement per day. This menu plan can be used as a
    guideline for the management of the boarding schools to provide healthy diet meals
    for their students.

    This paper presents the work of investigating and comparing the uses of CRS and QTC Pills
    as a tactile sensor material for Robotic Hand application. The materials were tested for their resistivity
    characteristics to determine the data reproducibility of the materials. The experiments were conducted
    based on three parameters; the supply voltage, the separation gap, and the sensor construction against
    the force/ load that had been exerted onto the materials. The results showed that CRS could cover the
    lower loading range when compared to QTC Pills. However, the data reproducibility of QTC Pills was
    better compared to those of CRS, thus making it more suitable to be used as a material for tactile
    sensing application. Therefore, this paper highlights the potential of these two materials as a tactile
    sensing transducer, and later, can be used as a useful guideline when designing a tactile sensor with
    these materials.

    Previous studies on instant noodles have been aimed mostly at secondary students, and have
    been concerned with the demographics, and the development of product attributes. Very few studies
    have examined the role of convenience (CO), product attributes (PA), advertising (AD) and subjective
    norms (SN) in predicting the intention of students towards the consumption of instant noodles. The
    present rising costs of living and education may affect the intention and behaviour of university students
    towards the consumption of affordable food. Therefore, the purpose of this paper was to explore the
    relationship between these variables and the variables of the Theory of Reasoned Action (TRA) in
    association with the intention of university students to consume instant noodles. A research model
    approach was used to reflect the effects of CO, PA, AD, and SN on the TRA constructs. In total, 390
    cases were gathered from three universities. Structural equation modelling was employed to assess the
    proposed research model in terms of the path significance, the general requirements for a model fit,
    and the testing of the hypotheses. It was found that AD has a direct positive effect on the behavioural
    intention of university students towards the consumption of instant noodles. Nevertheless, CO, PA, and
    SN appear to exert no significant influence on the behavioural intention of university students. The
    limitation of the study was that the findings were obtained from a small dataset covering only three
    universities. Therefore, future researches should cover a broader range of research samples. This paper
    provides additional understanding for marketing managers and researchers into the effects of CO, PA,
    AD and SN on the intention of Malaysian university students towards the consumption of instant
    noodles, which can be used for formulating marketing strategies for instant noodles and for considering
    future research directions in other countries.

    Face recognition has attracted significant attention due to its wide range of
    applications. Recently, researchers have focused on robust face recognition such as
    face recognition systems invariant to pose, expression and illumination variations.
    Illumination variation is still a challenging problem in the face recognition research
    area, especially for appearance-based approaches. This paper will discuss two main
    categories of the existing illumination methods namely frequency domain approach
    (DCT & DWT) and filtering approach. This includes the introduction of the
    representative algorithms, theories, and analyze the advantages and disadvantages of
    these algorithms correspondingly. The aim of this paper is to explore the technique
    and limitations of the existing illumination normalization strategies. Based on the
    reviews that have been conducted, it is found that the filtering technique is more
    effective when compared to the frequency domain technique. Hence, the implications
    of the review can help researchers to propose a novel idea in order to solve the existing
    problems and automatically improve the recognition performance.

    The academic performance of Malaysian students has recently been in the spotlight
    when it was revealed that our high schoolers had performed dismally in recent major
    international benchmarking studies. Malaysian students were not only ranked below
    the global average, but they also appear to be performing worse in Mathematics,
    Science and Reading Literacy compared the previous assessments. This has raised
    alarm among not only educational policy makers and academicians, but also other
    stakeholders who are directly or indirectly affected by the success or failure of the
    educational system. This study aims at empirically analysing the academic
    performance of students enrolled in the International Baccalaureate (IB) Diploma
    Program at Kolej MARA Banting (KMB) over a span of 23 years. It attempts to identify
    whether there is a similar declining trend as reported by PISA and TIMSS, and identify
    factors that accounted for the students’ performance. Students’ IB results from 1993
    to 2016 sourced from KMB database were analysed for trend and the strength of the
    relationship of subjects that contributed to the total points of the IB examination for
    two main programs offered at the college. Finally, future performance for the next
    three years was forecasted using time series analysis using ARIMA (1,0,0). The Mann
    Kendall Test confirmed existence of a downward trend in the students’ results.
    Correlational analyses found that high level subjects comprising of the High Level
    Chemistry, High Level Physics, High Level Biology and High Level Mathematics are
    highly correlated to IB examination results. This is accentuated further after a policy
    change in 2009 when the program for pre-Medical students opted for Standard Level
    Mathematics, instead of High Level Mathematics it used to offer. It is anticipated that
    the findings of this study will provide the relevant authorities with invaluable
    information with a view of instituting corrective measures.

    The contribution of attitudinal factors to the morphology of urban vegetation in cities
    has received very scanty attention. Most researchers in the developing countries
    including Nigeria focus on urbanisation, without paying significant attention to
    attitudinal factors. However, a lot of socioeconomic adjustments take place in cities in
    these countries, which result in the depletion of urban vegetation. The necessity to
    determine the contribution of attitudinal factors to the reduction in Akure urban
    vegetation has called for this study. The study analysed the contribution of attitudinal
    factors to the reduction of urban vegetation in the city. Previous studies on the city’s
    land use and land cover changes seemed to ascribe the city’s falling greenery to
    urbanisation only, without considering the contribution of attitudinal factors to the
    process. The paper posits that the indicators of attitudinal factors need to be properly
    understood in order to design appropriate policies to curb the phenomenon. Data
    were sourced through self-administered questionnaire from 317 participants. The data
    were analysed with SPSS Version 20 for the descriptive analysis, and Structural
    Equation Modelling (SEM), for the determination of the dominant factors. The KaiserMeyer-Olkin
    measure of sampling adequacy showed that the research instrument was
    internally consistent. Confirmatory factor analysis also achieved satisfactory goodness
    of fit indices. It was revealed that eight dominant attitudinal factors contributed to the
    reduction of urban vegetation in the city. These include misuse of road setback (0.72),
    not enough enlightenment or publicity (0.72), and failure of town planning authorities
    to enforce urban tree planting (0.72.) This shows that attitudinal factors contributed
    significantly to the depletion of urban vegetation in the city. The necessity for mass
    education and enlightenment towards behaviour change and pro-environmental
    behaviour, is stressed.

    This study was performed to review the conceptualization and relationships among user
    behaviour, system quality and intention to use eBidding, an eGovernment auction system with user
    satisfaction as the moderator. From the theoretical framework, user behaviour and system quality
    factors have significant relationships with the adoption of information system (IS). Empirical evidence
    also shows that satisfaction has a significant moderating effect on the relationship between system
    quality factors with the adoption of IS. Given the significant impact of behavioural factors of officials
    in eBidding adoption and role satisfaction on the intention and use of eGovernment system, system
    managers could introduce key changes in the workplace to increase satisfaction to address the problems
    of low eBidding adoption among users.

    A study on 2D geo-electrical resistivity imaging at Melaka Tengah, Malacca was conducted to determine the potential groundwater zone. This investigation is needed to identify the quality of the groundwater, since the site is located in the coastal areas where groundwater influence tends to diminish due to intrusion of seawater. Two resistivity lines were proposed with length of 400m each by using Terrameter SAS 4000 and ES1064. Geo-electrical of electrical resistivity and induced polarization method with the Wenner-Schlumberger configuration were carried out. The Res2Dinv software would then render the 2D resistivity image through inversion method which provided detailed information of both the laterally and vertically geological structures based on their part. The electrical resistivity measured the resistance of the subsurface to the flow of electric current in units of ohmmeters and value of chargeability during the transient decay of the applied voltage in ms for induced polarization. Well data provided was very useful in direct determination of subsurface soil lithology.The result obtained showed an 84.7-meter subsurface depth for both areas which then reflected that the subsurface consisted of two different layers namely overburden (laterite, clay, and/or peat soil) with ranged 1 ohm.m – 10 ohm.m and 50 ohm.m – 500 ohm.m for schist formation. However, this area was considered to be brackish water area because of the low chargeability value of 0ms – 1ms especially in top soil layer and 5ms – 20ms for schist formation. Thus, this area was deemed not suitable for groundwater exploration due to the intrusion of salt water.

    Meat tenderness is an important quality attribute that influences consumer acceptance. The application of mechanical treatment by mean to reduce toughness of meat cuts has gained much interest recently, with an intention to make use the lower grade meat cuts. This review deliberates the function, mechanism and numerous types of mechanical work in meat tenderization. The mechanical work employs to make meat softer by loosening the muscle structure and disrupting muscle cell. Previous studies have thoroughly examined the use of mechanical treatment (such as massaging, tumbling, and grinding) as an effective meat tenderization technique. Besides that, current research on newly emerging processing technology such as highpressure process (HPP) also shows potential to be explored. The application of mechanical work has shown impressive outcomes by reducing the shear force value that represents hardness of meat. The present paper also described the physical, biochemical and the structural changes of the meat. Finally, the improvements in the meat tenderness by using various type of mechanical work are presented in this paper.

    Honey is a natural sweetener, which is consumed in a variety of sweet products. It is
    considered as healthy food because it contains nutrients such as carbohydrate,
    protein, vitamins and mineral. The presence of adulterated honey in the market is
    worrying the consumers since it is difficult to distinguish between pure and adulterated
    honey due to similar appearance and texture of both type honeys. Chemometric
    analysis combined with spectroscopic data is a powerful technique that has been used
    to discriminate different type of honey. Samples of pure honey are collected from
    beekeepers at Ayer Keroh, Melaka and Cameron Highland, Pahang. The adulterants
    used to prepare adulterated honey are sugar and corn syrup with the concentration of
    the adulterants added to the pure honey ranging from 10% to 90% by weight of
    adulterant. All the samples are treated with heat at 40o
    C to ensure the adulterant and
    pure honey are mixed well. Fourier transforms infrared spectroscopy (FTIR) is used to
    generate the spectra of the honey and subsequently subjected to chemometric
    analysis. The spectra data is then analysed by using Principal Component Analysis (PCA)
    technique using SOLO+Mia software. In this study, all honeys have been successfully
    discriminated according to their origins and purity as well as types of adulterants used.
    Consequently, the developed model can potentially be used as a screening tool to
    determine the purity of honey in the market.

    Climate change is undeniably the greatest issue facing our society. Around the globe,
    increasingly unpredictable weather patterns and extreme weather events are
    observed, causing considerable risks to human lives, properties and health safety and
    also on the natural ecosystem. The magnitude and impacts of climate change are
    growing, and particularly in Malaysia, studies show increases in temperature and
    changes in rainfall regimes. Such changes have profound implications, especially for
    coastal communities. Since knowledge and perceptions of the public on climate change
    could affect the success of implemented adaptation and mitigation options, it is
    essential to conduct assessments to gather such information. A public awareness and
    perception study was conducted at Sabak and Tanjung Karang, two coastal
    communities which were affected by changes in sea level and flooding incidences. The
    knowledge level and perceptions of climate change among respondents were assessed
    covering areas such as level of awareness of the respondents, their perceptions of
    climate change issues, their sentiments on climate change and adaptation measures,
    their socio-economic activity and the effect on their lives. Results show that majority
    of respondents were aware of climate change issues and challenges. High levels of
    concern about climate change were expressed with the majority were worried and
    uncertain about the climate change impact and hoped for government measures.
    Almost half of respondents cited significant damage to their properties and reduction
    in income generation. Overall, the results of the present study gave insights of the
    affected parties on perceptions and awareness pertaining to climate change, which
    could potentially be used to promote greater awareness of climate change matters and
    to gauge the public response to related policies and strategies.

    A coconut de-husking machine comprising of two rollers with spikes, chain drives,
    presser, clearers, shafts and belting system was developed for small-scale production in rural areas.
    Performance test analysis showed that the machine de-husks coconut fruits without any nut breakage
    or distortion of the extracted fibre length. The objective of this project is to improve the efficiency and
    productivity in producing coconut fruits without husks by using the best selection of mechanical
    mechanisms with minimum costs. One electric motor (2hp, 1500rpm) is used to drive two shafts using
    a combination of pulley and belt. In between the motor and the shafts, one box of worm gears is used
    to reduce the rotation speed from 1500rpm to 21rpm (ratio 70:1). Two metal cylinders with a series of
    spikes are used to remove the husks from the coconut fruit and are attached to the rotary shaft. The
    machine’s average de-husking efficiency and capacity are 90.42% and 222 coconuts per hour,
    respectively. In addition, the development of the machine is also a solution to the constraint of space,
    whereby a compact-size machine is more suitable for small and medium enterprises (SME’s). Plus, it
    operates with lesser noise, which also contributes to a more viable operating condition for the
    environment.
