    Ocean wave energy is a renewable energy that is abundant on Earth. It is a concentrated
    form of solar energy where differential heating on Earth generate wind which transfer their energy into
    open water in form of waves. In relation to atmospheric emission, wave power is less environmentallydegrading
    than most other form of power generation. The fluctuating wave contains potential and
    mechanical energy which can be converted into electrical energy. A special device needs to be
    developed to harness the energy which is called Float Wave Energy Converter (FWEC). The purpose
    of this project is to design, fabricate and test the experimental model of FWEC. The efficiency of the
    model will be analysed based on wave power and power generated. The model are capable to generate
    power for small devices with low power consumption. The power generated from designated FWEC
    will be depends on several parameters which is wave amplitude, diameter ratio and shape of the model.
    This parameter would be used to determine the best design for FWEC. Copyright © 2015 Penerbit

    Nowadays, intelligent vehicles have received a considerable attention among the
    researchers to reduce the number of collisions and road accidents. One of the
    challenging tasks for these vehicles is road lane detection or road boundaries
    detection. In this research, a lane detection algorithm was developed to detect the
    right and left lane markers on the road by using two cameras which act as a stereo
    vision for the system. It is based on edge detection by using Canny Edge Detection to
    reduce unnecessary data on the images and to perform features recognition for the
    lane. After the features has been extracted, the algorithm is followed by Hough
    Transform method to generate the detected lines on the image obtained from the
    stereo vision camera. The algorithm has to work in different environment to be used
    in real world applications. The stereo vision algorithm is implemented to generate
    disparity map of area. This helps to gain more information on environment, such as the
    estimated distance of the lines, the distance of the vehicle to the turns. The experiment
    result shows the detection of right and left lane on the road with disparity map to
    determine an estimate of the distance of detected lanes from the stereo vision camera.

    Computer vision is applied in many software and devices. The detection and
    reconstruction of the human skeletal structure is one of area of interest, where the
    camera will identify the human parts and construct the joints of the person standing in
    front. Three-dimensional pose estimation is solved using various learning approaches,
    such as Support Vector Machines and Gaussian processes. However, difficulties in
    cluttered scenarios are encountered, and require additional input data, such as
    silhouettes, or controlled camera settings. The paper focused on estimating the threedimensional
    pose of a person without requiring background information, which is
    robust to camera variations. Each of the joint has three-dimensional space position and
    matrix orientation with respect to the sensor. Matlab Simulink was utilized to provide
    communication tools with depth camera using Kinect device for skeletal detection.
    Results on the skeletal detection using Kinect sensor is analysed in measuring the
    abilities to detect skeletal structure accurately, and it is shown that the system is able
    to detect human skeletal performing non-complex basic motions in daily life.

    Nowadays, the applications of tracking moving object are commonly used in various
    areas especially in computer vision applications. There are many tracking algorithms
    have been introduced and they are divided into three groups which are generative
    trackers, discriminative trackers and hybrid trackers. One of the methods is TrackingLearning-Detection
    (TLD) framework which is an example of the hybrid trackers where
    combination between the generative trackers and the discriminative trackers occur. In
    TLD, the detector consists of three stages which are patch variance, ensemble classifier
    and KNearest Neighbor classifier. In the second stage, the ensemble classifier depends
    on simple pixel comparison hence, it is likely fail to offer a better generalization of the
    appearances of the target object in the detection process. In this paper, OnlineSequential
    Extreme Learning Machine (OS-ELM) was used to replace the ensemble
    classifier in the TLD framework. Besides that, different types of Haar-like features were
    used for the feature extraction process instead of using raw pixel value as the features.
    The objectives of this study are to improve the classifier in the second stage of detector
    in TLD framework by using Haar-like features as an input to the classifier and to get a
    more generalized detector in TLD framework by using OS-ELM based detector. The
    results showed that the proposed method performs better in Pedestrian 1 in terms of
    F-measure and also offers good performance in terms of Precision in four out of six
    videos.

    Phishing detection is a momentous problem which can be deliberated by many
    researchers with numerous advanced approaches. Current anti-phishing mechanisms
    such as blacklist-base anti-phishing, Heuristic-based anti-phishing does suffer low
    detection accuracy and high false alarm. There is need for efficient mechanism to
    protect users from phishing websites. The purpose of this study is to investigate the
    capability of 6 machine learning algorithms i.e. Multi-Layer Perceptron (MLP), Support
    Vector Machine (SVM), Random Forest (RF), Decision Tree (DT), Logistic Regression
    (LR) and Naïve Bayes (NB) to classify phishing and non-phishing websites. These
    algorithms were trained with two different groups of training in WEKA environment
    and then were tested in terms of accuracy, precision, TP rate, and FP rate on a 3
    different sets of dataset which contains dissimilar portion of phishing and non-phishing
    instances. Results presented that Naïve Bayes classifier has better detection accuracy
    between other classifiers for predicting phishing websites while Multi-Layer
    Perceptron gave worst result in terms of detection accuracy. The result also showed
    that Support Vector machine has better FP rate between other classifier. In addition,
    Random Forest, Decision Tree, and Naïve Bayes can classify all phishing websites as
    phishing correctly. It means that TP rate is 100% for these classifiers. In conclusion this
    paper suggests using NB as the best classifier for predicting phishing and non-phishing
    websites.

    Energy consumption of Wireless Sensor Networks (WSN) is an important aspect in
    the design requirement. This is especially true in a situation where WSN is being
    operated in isolated areas and thus relying on batteries due to unavailability of power
    infrastructure. Since energy efficiency is the main concern in the deployment of WSN,
    the sensor node must keep track of the charge that is left in the battery, commonly
    referred as the State of Charge (SoC). To prevent the discontinuation of the operation
    of the sensor node from power cut off, it is important to find an analytic model for
    the battery’s state of charge. In this paper, an optimized structure of Multi-Layer
    Perceptron (MLP) is utilized to obtain a model of the battery state-of-charge in
    wireless sensor nodes. Results show the suitability of the method that produces
    accurate and simple models, capable of being implemented even in low cost and very
    constrained real motes.

    Piano technique is one of the main part of piano playing. Some researches had
    attempted to unveil the technique of virtuoso pianists using technologies. These
    researches employ different types of sensors in order to capture motion data of piano
    playing. However, one area in this research had been under-represented, which is
    finger position and pressure measurement applied by the musician while playing the
    musical instrument. Research that embark on this area faced a common problem, the
    sensors used in these research are directly in contact with the pianist, which causes a
    change of piano playing experience. Since piano playing consists of very delicate
    interaction between the pianist and the piano, such change of experience may affect
    the pianist’s performance. These sensors are considered to be intrusive to the piano
    playing experience. Concluding the challenges faced by current technologies, a nonintrusive
    sensor is proposed and the circuit design of the sensor is discussed in this
    paper.

    Microbial Fuel Cell (MFC) is a device that generates electricity from the metabolism of
    bacteria simultaneously treats wastewater by decolourizing the azo dye in wastewater.
    In this work, the effect of different external loads and bacterial loads were examined.
    The maximum open circuit voltage generated was 390 mV by using 7 consortia of
    bacteria while the maximum current generated was 50 µA using 10 Ω resistor. 97%
    decolourization efficiency of 0.1 g/L of azo dye was achieved after 5 days of operation.
    Besides, the maximum current density and power density achieved were 17.9 µA/cm2
    and 460 µW/cm2
    respectively. Polarization curve was plotted and Scanning Electron
    Microscope was applied to visualize the bacterial community attachment onto the
    graphite felt electrode. Cyclic voltammetry was applied to study the redox properties
    of the Azo dye using microorganisms in MFC. Overall, these 7 bacterial strains used in
    this work showed the capability in decolourizing the Azo dye simultaneously producing
    electricity in MFC.

    The probability of the construction accident to happen is high due the nature of
    Construction work that involves complex activities, methods, machineries, materials
    and hazards. The occupational safety and health (OSH) law and regulations are
    mandatory for every construction project to uphold. Responsibilities to ensure the
    safety and health at the workplace lies with those who create the risk and with those
    who work with the risk. The owner or client of the construction project has the upper
    hand in determining the standard of OSH implementation in their project through
    contract documents. If the contract documents comprehensively spell out OSH
    requirements and cover all OSH cost, then the issues of contractor not implementing
    OSH measures could be minimized. The objective of this study is to identify
    Occupational Safety and Health requirements (OSH) in the contract document of
    selected construction projects. To achieve this objective, a total of seven contract
    document was collected from several construction companies. The qualitative analysis
    was performed to identify the extent of OSH requirements and costs are being
    mentioned in the contract documents. The finding shows that most of the contract
    document contains very little emphasis on OSH requirements and budgeting. Only one
    contract contains, an appendix that spell out about the safe work practices for
    construction works. The visible allocated budget for OSH requirements for all seven
    contracts is very minute range from 0.21% to 1.99% of contract value. In order to
    ensure that occupational safety and health is properly implemented, safety needs must
    be included in the budget because implementation it is not free, this can be achieved
    by making it a permanent feature in all bills of quantity of the project.

    Due to high energy demand worldwide, finding an alternative renewable and
    sustainable energy source is of great interest. Plant microbial fuel cell (P-MFC) is one
    of the most promising methods to generate green energy. In P-MFC, a plant is placed
    into the anode compartment. Mutual interaction between plant root rhizodeposits
    and bacterial community results in the biofilm formation at the vicinity of the
    rhizosphere area in plant root could be utilized to generate electricity. Indeed, in PMFC,
    bacteria metabolize rhizodeposits into electrons and protons. These electrons
    could be then converted into green electricity. The objectives of this research are to
    utilize Epipremnum aureum plant collected from Kota Tinggi’s lake to generate
    electricity and observe current generation by different resistors, to characterize
    immobilized bacteria attached on the anode surface then identify the optimum growth
    temperature for isolated bacteria. Five plant microbial fuel cells were constructed in a
    H-shape (dual- chambers) configuration in the plastic container. Maximum current
    density for 20 days for P-MFC by external resistance of 100k Ω was 0.1 µA/cm2
    with
    maximum power density of 0.85 µW/cm2 and the open circuit voltage (OCV) was
    measured at 195 mV. Besides, fresh biomass averages increased 5g after 20 days of
    experiments below and above ground as compared to the initial fresh biomass. Five
    isolated bacterial strains from the graphite felt surface found on the anode were
    screened by nine biochemical tests such as catalase, TSI (triple sugar iron agar), gelatin
    and etc. The immobilized bacteria attached to anode electrode in P-MFC were further
    examined with Fast Electron Scanning Electron Microscopy (FESEM). The isolated
    bacterial growth curves were determined at two different temperatures of 25 °C and
    37 °C. The optimum growth temperature predominantly for them was 37 °C.

    In this study, we investigate the ability of the bacterial isolates from an Iraqi oil
    reservoir, namely POS and PCO Oil to decolorize commercially used model azo dye Acid
    Red-27(AR-27). The effects of inoculation volume and glycerol concentrations were
    optimized to develop an economically feasible decolourization process. The isolates
    were able to decolourize azo dye (AR27) at the highest decolorization efficiency of 98%
    in 10 mL bacterial solution consisted of POS and PCO Oil and in the presence of 6.34
    g/L glycerol. An optimized MFC using this bacterial consortium (POS + PCO Oil) and
    graphite rod electrodes produced a maximum open circuit voltage (OCV) of 175 mV, in
    the presence of potassium ferricyanide as the electron acceptor at the cathode. The
    maximum current density of 1.7 μA/cm² and power density of 59.3 μW/cm² were
    achieved when an external load of 5 kΩ was applied. Morphological analysis was
    performed using Scanning Electron Microscope (SEM) to prove the bacterial
    attachment onto the anode surface (graphite rod) in the MFC operation. This work
    proposed that the bacterial strains POS and PCO Oil possess the ability to decolorize
    Azo dye AR27 and generate electricity in the absence of nitrogen source.

    Many nonlinear problems that arise in various science and engineering fields can be
    modelled by the Goursat partial differential equations. Modelling these non-linear
    problems using the Goursat partial differential equations has not received much
    attention especially the theoretical aspect . The proposed scheme of solution is
    supported by examining a nonlinear Goursat problem. The verification of the
    theoretical results from several series of numerical experiments are discussed. Results
    obtained from Taylor series expansion show that the proposed new scheme is
    consistent. By using the von Neumann analysis and essence of stability, the proposed
    new scheme is found to be unconditionally stable. In addition, the trend of the
    numerical results shows that the new scheme is also convergent.

    Aggregate planning acts as a blueprint for all operational planning activities. Despite
    the substantial amount of research that has been done in determining methods to
    improve aggregate planning approaches, the industry is still at a loss when it comes
    to working on the tactical planning aspect, especially in aggregate production.
    Therefore, this research work aims to present a comprehensive and generalised
    framework that will formulate a realistic batch production environment using an
    interactive Production Decision Support System. This system consists of an aggregate
    planning framework that combines a simulation model and a Pinch Analysis graphical
    approach to improve the effectiveness and efficiency of the decision-making process.
    The target is to allow operational opportunities to be captured at first sight and thus,
    maximise organisational profit. The simplicity and practicality of this new Production
    Decision Support System is demonstrated through two illustrative examples where a
    total of four heuristics were identified and turned into the new strategies to avoid the
    stock-out scenarios.

    In the local path planning navigation, a particular focus is given to local minimum
    problem. This problem occurs when a robot manoeuvre towards a desired target with no initial
    information of the environment and gets trapped in an infinite loop or also known as a dead
    end trap. Besides the local minimum situation, there are even worse situation in which when a
    mobile robot encounters two or more dead ends in a row. This situation is known as “multiple
    minimum” situation. The situation is forming more complicated problem than the local
    minimum situation. In this paper, a complete review is given on the local minimum and multiple
    minimum problems and the available solutions for these situations are discussed in detail.

    This study was conducted to investigate the effect of particle size and polydispersity index
    (PDI) by changing the concentration of active ingredient and solid lipid in the Orthosiphon stamineus
    (O. stamineus) loaded nanostructured lipid carrier (NLC) formulation. O. stamineus extract was
    prepared by maceration method. From the HPLC analysis, the O. stamineus extract contains 38%
    sinensetin and 62% rosmarinic acid. The method used to prepare the formulation of O. Stamineus
    loaded NLC is melt emulsification homogenization technique. Solid and liquid lipid used were glyceryl
    monostearate and triglyceride respectively. It was found that the size of particles increased as
    increasing in concentration of active and solid lipid in the formulation. The best range for concentration
    of active and solid lipid are 1-4% and 1-3% respectively since the particle size and PDI needed are
    below 200 d.nm and 0.2. Collectively, based on particle size and PDI results show that the NLC system
    is highly potential to be a carrier of transdermal delivery for O. stamineus. Copyright © 2015 Penerbit

    This paper investigated the influence of temperature and binder speed rate as a process
    variable towards amount of ammonia emission (NH3) in the fluidized bed top spray granulation.
    Response Surface Method (RSM) was employed in this experiment to optimize the process parameters
    in a top-spray fluid-bed processor. Three significant variables (binder feed rate, atomize pressure and
    temperature) were selected for the optimization studies. The statistical model was constructed via
    central composite design (CCD) using three screened variables. These methods are exclusively used to
    examine the "surface," or the relationship between the response and the factors affecting the response.
    The response in this experiment is the quantity of gas release, then the goal would be to find the factor
    settings that minimize the amount.The inlet temperature was identified as the most critical parameter,
    followed by the binder addition rate and atomize pressure, respectively. Copyright © 2016 Penerbit

    The construction organization contributes to the generation of large quantities of
    construction waste across Nigerian cities. Nigeria has been known to lack appropriate procedures for
    managing construction waste, and developers and their contractors are left with the collection and
    disposal of construction waste management, despite the fact that they are expected to embrace all
    administrative, financial, legal, planning, and technological functions involved in solutions to all
    problems of construction waste. Therefore, this leads to ineffective construction waste management.
    This paper examines the effect of the government policy on the relationship between organizational
    resources and construction waste management among construction organizations, in Abuja, Nigeria. A
    quantitative method of survey was used to obtain data from managers of construction project-based
    organizations in Abuja, Nigeria. A total of 310 questionnaires were administered and 178 usable
    questionnaires were returned, yielding 57.4 response rate. Partial least square Structural equation
    model (PLS-SEM) was used to analyse the data. The Cronbach’s Alpha value for the variables ranging
    from 0.885 to 0.972 indicates a very good reliability of the research instrument. It was found that all
    the hypotheses are significant at 5% significance level. It was found that while government policy
    moderates the relationship between the Transformational leadership as a dimension of organizational
    resources and construction waste management, it does not support organizational learning and staff
    training. Copyright © 2016 Penerbit Akademia Baru - All rights reserved.
