    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.

    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.

    A comfortable work space is important to produce productive work performance among workers. In Malaysia, the condition of office environment and its related issues on thermal comfort are fairly new. Past studies shown that the increment of energy consumption in high rise offices tend to increase dramatically. This is because the consumption of air condition for cooling accounts in office buildings had increased from 40% to 60% in recent years and the total electricity usage for office units also rises intensely due to urban heat island (UHI) resulted from modification of land surfaces. The objective of this paper therefore is to investigate the conditions and problems of existing prominent high rise office in Kuala Lumpur which is IBM Plaza and Menara Mesin Niaga in the scope of thermal comfort as well as describes an integrated passive design approach to reduce the cooling requirement for high-rise office building through an improved building envelope design using green technologies like external wall cladding following the GBI standard. This paper also attempts to get the user perception towards their existing workspace. For this purpose, case study as research strategy is adopted using mixed methodology combining qualitative and quantitative method under the framework of interpretivism and positivism research paradigm. Findings indicate that external wall cladding made of composite aluminium provides much advantages to the user. This study is important because appropriate design principles by adopting appropriate building envelope made of suitable material addressing ecology issues will not only provide a comfortable living environment to the users but also established referential guideline for future designers and scholars whom interested in office design.

    In accordance upon conservation efforts, this research emphasizes on prevention of
    environmental pollution and considers the elements of sustainable of infrastructure
    construction materials, which is interlocking pavement block. The development of this
    innovative product apply the concept of 3Rs and waste to wealth by using the
    agricultural waste product, coconut shell, where widely available with very minimum
    cost worldwide especially in tropical country such as India, Indonesia, Philippines,
    Thailand and Malaysia. The main objective of this research is to produce an
    environmental friendly product with a good quality, low cost and lightweight known as
    Green Interlocking Pavement (GIP Block). The chemical composition of coconut shell
    ash and ordinary Portland cement being identified and compared to know whether it
    is able to react as a good binder in the mixture or not. The quality of GIP Block
    considered is compressive strength, water absorption and bulk density. All the blocks
    were curing in seven and 28 days before implementing the entire test. The existing
    interlocking pavement used as bench mark and GIP Block 0% of proportion of coconut
    shell ash used as control variables. The specimen of the interlocking pavement
    prepared in this research is 10%, 20% and 30% proportion of coconut shell ash to
    partially replace the quantity of cement. The ratio of the interlocking pavement apply
    in this research is 1:2 which stand for one part cement and two part of sand. The
    findings withdrawn from this research are: first, the chemical characteristic of the
    coconut shell ash and cement. Second, the value of bulk density slightly reduces as the
    percentage of coconut shell ash increases. Third, the additional of coconut shell ash to
    partially replace the quantity of cement in the product reduce the compressive

    The use of concrete for construction had become very common in developing countries. But concrete is not friendly environment because of it consumes huge quantities of natural materials and production of the cement, which is a major contributor to greenhouse gas emissions and global warming. The aim of this study is to investigate the Sustainable Green Concrete (SGC) which containing biomass aggregate; fly ash and Superplasticizer. Biomass aggregate and fly ash are waste industry products which are environmentally friendly. The study was carried out to identify the chemical properties of biomass aggregate, and to determine the chemical properties and optimum mix design of the Sustainable Green Concrete (SGC). A total of 90 cube samples were casted and compressive strength were tested at the age of 7, 14 and 28 days. The overall results showed that the workability and compressive strength were decreased with the increase of the replacement of natural aggregate with biomass aggregate. Besides that, the workability and compressive strength was increased with the incorporation with the replacement cement by fly ash. The SGC gained highest compressive strength for the concrete mixes of 39.3 N/mm2 with the optimum percentage used of SGC in producing concrete not exceeding 30% biomass aggregate and 6% of fly ash as a partial replacement with natural aggregate and cement respectively. The results obtained and observation made in this study suggested that biomass aggregate and fly ash are successfully used as partial replacement in producing SGC and can perform better strength development.

    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.

    In Malaysia, it is estimated that almost 80 percent of the world's population today used palm oil in their daily lives. Malaysia is the second country exporting palm oil, about 39 percent of world palm oil output. Besides that, Malaysia also recorded about 44 per cent of world exports, making the palm industry very important for countries other than rubber and cocoa. However, to keep the palm industry running smoothly and constantly, there are many challenges to face. One is to maintain soil fertility because the soil can affect the growth of oil palm trees. With the use of this system, it will show the condition of soil behaviour to the farmer about the treatment given. Arduino board is used in this project which it is programmed to calculate and display the level of soil condition by using temperature sensor and soil moisture sensors as an input. This sensor will detect the level of soil moisture and temperature and it is easier for farmers to monitor the soil conditions. Controlled soil conditions can improve the soil's ability to maintain the fertility of palm trees and help plant growth suit to the weather and local climate.

    Rock with moderate strengths (20 to 70 MPa) effectively excavated by ripping
    method which is considered as shallow excavation or surface striping method.
    Disputed between client and contractor often occur due to the lack of proper
    assessment to determine the rippabality of hard material. Practically, rippability of in
    situ rock is assessed based on field ripping test that being conducted using actual
    ripper dozer which is time-consuming and expensive. Therefore the assessment of
    rippability of rock based on specific laboratory tests able to resolve the conflict that
    occurs on ripping method. The correlation between specific energy with surface
    hardness and tensile strength is chose as the material properties to assess in order to
    determine the rippability of rock in this study. Few samples of Sandstone undergone
    several laboratory tests such as laboratory ripping test, Brazilian's test and Schmitt
    hammer test in order to obtain the required parameters in this study. The average
    tensile strength (σT) obtained was 4.62MPa with a range of value from 3.19 to 7.50
    MPa whilst the average rebound number (R) obtained for Sandstone was 26.6 with a
    range between 19.0 and 34.0. The specific energy (SE) obtained indicates an average
    value of 3.95 MJ/m3
    with a range value between 1.73MJ/m3
    and 6.45 MJ/m3
    . The
    correlation of R and σT with SE shows a relatively good relationship. Parameters of R
    and σT are acceptable and reliable for assessing rippability of Sandstone based on the
    value of regression coefficient (R2) which is consistence above 0.8 for both
    correlation between SE, R and σT.

    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.

    Flipped Classroom enables instructors to spend more time for hands-on problem-solving instruction compared to the traditional pedagogical model which involves lectures. The purpose of this study is to determine the need for a problem-solving flipped classroom module to be designed for the STM3023: Internet of Things (IoT) subject offered at the Certificate level at Malaysian Community Colleges. A structured interview was conducted with 16 lecturers from 14 Community Colleges offering the subject to obtain their views on current teaching practices along with the challenges faced in the teaching and learning of IoT to entry level students. Participants were also asked about their readiness towards the flipped classroom following an orientation session on Flipped Classroom approach. The findings showed that lecturers mostly used traditional pedagogical models in the TVET settings such as lectures. Students usually followed instructions and merely replicate the hands-on tasks as demonstrated by their lecturers in class. It was also found that students were struggling with the subject due to their lack of competency in programming and grasping electrical and electronics concepts. Students were also found to be weak in mathematics and reasoning skills, thus making it a challenge to teach IoT to them. Therefore, a myriad of media, materials and application of real-world concepts may be required to aid lecturers to improve students’ achievement in the subject. The flipped classroom approach for teaching which gives more time for hands-on problem-solving instruction may be appropriate to support lecturers to overcome the challenges in teaching IoT.

    Recently natural polyphenol compounds (PCs) of plants, gained wide consideration of
    scientists, companies and public people because of its unique pharmaceutical and
    preservative benefits in the physiological system. They can prevent mortal and serious
    diseases such as cancer, cardiovascular and Alzheimer. However, defining a suitable
    source of PCs and their proper, economic and efficient extraction method are still a
    challenge. The aim of this study was to review PCs as an important antioxidant, the
    significance of pomegranate as a source of natural PCs and its application in meat and
    meat product. This study also covers different types of PCs extraction methods such as
    solid-liquid extraction (SLE) method as a conventional extraction which using Soxhlet
    apparatus and several solvents and advanced methods such as microwave-assisted
    extraction (MAE), supercritical fluid extraction (SFE), accelerated solvent extraction
    (ASE), ultrasound-assisted extraction (UAE) and high hydrostatic pressure extraction
    (HHPE). Simple and developed analytical method of PCs is also reviewed in the study.
    SLE method is an easy and simple method but, it uses lots of chemicals and is not
    suitable for all kinds of PCs extraction. UAE is using for quick extraction PCs, SFE is green
    extraction method uses less solvent and have a good result but it needs high
    technology. ASE method is a proper alternative for Soxhlet extraction method for its
    quick result. MAE method has high extraction result but is not suitable for some
    thermolabile PCs. Several parts of pomegranate showed antioxidant and antimicrobial
    traits for shelf life extension of meat and meat product. Pomegranate peel is the
    strongest antioxidant followed by pomegranate juice and seed. Pomegranate peel
    prolonged chilled chicken meat shelf live up to three weeks.

    Phytoremediation is considered as a cost-effective and environmentally friendly
    technique for decontaminating environments that have been contaminated with
    heavy metal ions. The technique describes the use of plants and their concomitant
    microbes to mitigate environmental contaminations. However, conventional
    remediation techniques like chemical, thermal and physical treatment methods are
    too costly, and may end of causing more contamination to the environment.
    Phytoremediation practice provides a major information on the utilization of plants
    and their materials in decontaminating polluted environments. Heavy metals and
    other organic contaminants are among the most precarious substances released into
    the environment which have an eminent level of toxicity and sturdiness of both
    aquatic and terrestrial organisms. The review aimed at providing a broad
    understanding of utilizing various plants and their materials in decontaminating
    polluted environments with heavy metals and other organic contaminants. It also
    provided the general methods used in treating the aforementioned contaminants in
    an environment. The review further discussed the classes of phytoremediation like
    phytoextraction, phytovolatilisation, phytostabilization, phytotransformation,
    phytodegradation and phytofiltration. The generalized advantages and disadvantages
    of phytoremediation were ultimately highlighted.
