    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.

    MyJurnal
    Facility Layout Problem (FLP) is a NP-hard problem concerned with the arrangement of facilities as to minimize the distance travelled between all pairs of facilities. Many exact and approximate approaches have been proposed with an extensive applicability to deal with this problem. This paper studies the fundamentals of some well-known heuristics and metaheuristics used in solving the FLPs. It is hoped that this paper will trigger researchers for in-depth studies in FLPs looking into more specific interest such as equal or unequal FLPs.

    Several modern treatment strategies have been adopted to combat cancer with the aim of minimizing toxicity. Medicinal plant-based compounds with the potential to treat cancer have been widely studied in preclinical research and have elicited many innovations in cutting-edge clinical research. In parallel, researchers have eagerly tried to decrease the toxicity of current chemotherapeutic agents either by combining them with herbals or in using herbals alone. The aim of this article is to present an update of medicinal plants and their bioactive compounds, or mere changes in the bioactive compounds, along with herbal edibles, which display efficacy against diverse cancer cells and in anticancer therapy. It describes the basic mechanism(s) of action of phytochemicals used either alone or in combination therapy with other phytochemicals or herbal edibles. This review also highlights the remarkable synergistic effects that arise between certain herbals and chemotherapeutic agents used in oncology. The anticancer phytochemicals used in clinical research are also described; furthermore, we discuss our own experience related to semisynthetic derivatives, which are developed based on phytochemicals. Overall, this compilation is intended to facilitate research and development projects on phytopharmaceuticals for successful anticancer drug discovery.

  5. Prediction of tool life in end milling of Ti-6A1-4V alloy using artificial neural network and multiple regression models
    SALAH AL-ZUBAIDI, JAHARAH A. GHANI, CHE HASSAN CHE HARON
    Sains Malaysiana, 2013;42:1735-1741.
    Tool life of the cutting tools is considered as one of the factors which has effects on machining costs and the quality of machined parts. The topic of tool life prediction has been an interesting and important research topic attracting the attention of a wide number of researchers in this particular area. In terms of the suitable methods used in this research topic, it is stated that both statistical and artificial intelligence (AI) approaches can be employed to model tool life. For further justifying the capability of the ANN model in predicting tool life, the current study was based on conducting experimental work for collecting the experimental data. After carrying out the experiment, 17 data sets were collected and they were divided into two subsets; the first one for training and the second for testing. Since the data sets seemed to be lower than the number of data sets used in previous studies, we attempted to make verification of the ability of the ANN model in learning and adapting with low training and testing data. Diverse topologies accompanied with single and two hidden layers were created for modeling the tool life. For choosing the best and most effective network, the study adopted the mean square error function as criteria for the evaluation of the network selection. Thus, based on the data generated from the same experiment, a regression model (RM) was constructed employing the SPSS software. A comparison between the ANN model and RMs in terms of their accuracy was carried out and the findings revealed that the accuracy of the ANN was higher than that of the RM.

  6. Sensitivity analysis of the refinement to the mann-whitney test
    Abdul Rahman Othman, Lai CH
    Sains Malaysiana, 2014;43:1095-1100.
    The aim of researchers when comparing two independent groups is to collect large normally distributed samples unless they lack the resources to access them. In these situations, there are a myriad of non-parametric tests to select, of which the Mann Whitney U test is the most commonly used. In spite of its great advantages of usage, the U test is capable of producing inflated Type I error when applied in situation of heterogeneity or distinct variances. This current study will present a viable alternative called the refined Mann-Whitney test (RMW). A Monte Carlo evaluation test is conducted on RMW using artificial data of various combinations of extreme test conditions. This study reviews that the RMW test justified its development by enhancing the performance of the U test. The RMW test is able to control well its Type I error rates even though it has a lower power.

  7. Representing landslides as polygon (areal) or points? How different data types influence the accuracy of landslide susceptibility maps
    Simon N, de Roiste M, Crozier M, Abdul Ghani Rafek
    Sains Malaysiana, 2017;46:27-34.
    In the literatures, discussions on the accuracy of different models for landslide analysis have been discussed widely.
    However, to date, arguments on the type of input data (landslides in the form of point or polygon) and how they affect
    the accuracy of these models can hardly be found. This study assesses how different types of data (point or polygon)
    applied to the same model influence the accuracy of the model in determining areas susceptible to landsliding. A total
    of 137 landslides was digitised as polygon (areal) units and then transformed into points; forming two separate datasets
    both representing the same landslides within the study area. These datasets were later separated into training and
    validation datasets. The polygon unit dataset uses the area density technique reported as percentage, while the point
    data uses the landslide density technique, as means of assigning weighting to landslide factor maps to generate the
    landslide susceptibility map that is based on the analytical hierarchy process (AHP) model. Both data groups show striking
    differences in terms of mapping accuracy for both training and validation datasets. The final landslide susceptibility
    map using area density (polygon) as input only has 48% (training) and 35% (validation) accuracy. The accuracy for
    the susceptibility map using the landslide density as input data achieved 89% and 82% for both training and validation
    datasets, respectively. This result showed that the selection of the type of data for landslide analysis can be critical in
    producing an acceptable level of accuracy for the landslide susceptibility map. The authors hope that the finding of this
    research will assist landslide investigators to determine the appropriateness of the type of landslide data because it will
    influence the accuracy of the final landslide potential map.

  8. Fulltext A Review on the Kenaf/Glass Hybrid Composites with Limitations on Mechanical and Low Velocity Impact Properties
    Ahmad Nadzri SNZ, Hameed Sultan MT, Md Shah AU, Safri SNA, Basri AA
    Polymers (Basel), 2020 Jun 04;12(6).
    PMID: 32512701 DOI: 10.3390/polym12061285
    Environmental awareness and trends to develop sustainable resources have directed much research attention towards kenaf fibre as an alternative reinforcement in composite manufacturing. Numerous studies have been conducted on kenaf and its hybrid composites. Most studies were conducted on kenaf/glass hybrid composites compared to other kenaf/synthetic hybrid composites. Similar with other materials, mechanical properties were the fundamental knowledge identified by the researcher. Limited studies conducted on other properties have restricted the use of kenaf composites to non-structural applications. To extend the potential of kenaf composites to automotive exterior or other critical applications, studies on impact properties can be a valuable contribution in the material field. This review discusses the mechanical and low velocity impact properties of kenaf/glass hybrid composites reported previously. Percentage loading of fibre, the angle of orientation in woven fibres and the chemical treatment applied to the fibre before compounding are the three major parameters that affect the mechanical and impact properties of the composites. This review provides insights into the mechanical and impact properties of kenaf/glass hybrid composites for future research.

  12. Fulltext Toward developing a sustainability index for the Islamic Social Finance program: An empirical investigation
    Widiastuti T, Prasetyo A, Robani A, Mawardi I, Rosida R, Al Mustofa MU
    PLoS One, 2022;17(11):e0276876.
    PMID: 36413519 DOI: 10.1371/journal.pone.0276876
    Several previous studies state that the Islamic Social Finance program has not fully succeeded in creating prosperity, and there are no definite measurements to show the sustainability impact of the program. Thus, a measurement is needed to analyze various aspects in achieving the success and sustainability of Islamic social finance programs. This study developed an index for performance evaluation with an emphasis on the success and sustainability of the Islamic Social Finance program. The study used the Analytical Network Process to determine and analyze priority components. Furthermore, the Multistage Weighted Index method was used to calculate the final index score. The index was built by taking into consideration various factors, stakeholders, aspects, and indicators. This study indicates that aspects of funding contribution from donors (0.22), involvement of donors in giving advice (0.99), and controlling of supervisor (0.08) are priority aspects in the success and sustainability of the program. An empirical investigation was performed on three different programs in Indonesia: A, B, and C. Program A (0.81) and C (0.80) have succeeded in improving the beneficiaries' quality of life to the level of economic resilience, although at a low level of sustainability (76-84.33). On the other hand, program B (0.73) is at the economic reinforcement and has not yet achieved sustainability. This index can be seen as a comprehensive tool for measuring the success and sustainability of the program at several levels.

  13. Fulltext An empirical study on Resource Description Framework reification for trustworthiness in knowledge graphs
    Govindapillai S, Soon LK, Haw SC
    F1000Res, 2021;10:881.
    PMID: 34900233 DOI: 10.12688/f1000research.72843.2
    Knowledge graph (KG) publishes machine-readable representation of knowledge on the Web. Structured data in the knowledge graph is published using Resource Description Framework (RDF) where knowledge is represented as a triple (subject, predicate, object). Due to the presence of erroneous, outdated or conflicting data in the knowledge graph, the quality of facts cannot be guaranteed. Trustworthiness of facts in knowledge graph can be enhanced by the addition of metadata like the source of information, location and time of the fact occurrence. Since RDF does not support metadata for providing provenance and contextualization, an alternate method, RDF reification is employed by most of the knowledge graphs. RDF reification increases the magnitude of data as several statements are required to represent a single fact. Another limitation for applications that uses provenance data like in the medical domain and in cyber security is that not all facts in these knowledge graphs are annotated with provenance data. In this paper, we have provided an overview of prominent reification approaches together with the analysis of popular, general knowledge graphs Wikidata and YAGO4 with regard to the representation of provenance and context data. Wikidata employs qualifiers to include metadata to facts, while YAGO4 collects metadata from Wikidata qualifiers. However, facts in Wikidata and YAGO4 can be fetched without using reification to cater for applications that do not require metadata. To the best of our knowledge, this is the first paper that investigates the method and the extent of metadata covered by two prominent KGs, Wikidata and YAGO4.

  14. Fulltext A collaborative approach for research paper recommender system
    Haruna K, Akmar Ismail M, Damiasih D, Sutopo J, Herawan T
    PLoS One, 2017;12(10):e0184516.
    PMID: 28981512 DOI: 10.1371/journal.pone.0184516
    Research paper recommenders emerged over the last decade to ease finding publications relating to researchers' area of interest. The challenge was not just to provide researchers with very rich publications at any time, any place and in any form but to also offer the right publication to the right researcher in the right way. Several approaches exist in handling paper recommender systems. However, these approaches assumed the availability of the whole contents of the recommending papers to be freely accessible, which is not always true due to factors such as copyright restrictions. This paper presents a collaborative approach for research paper recommender system. By leveraging the advantages of collaborative filtering approach, we utilize the publicly available contextual metadata to infer the hidden associations that exist between research papers in order to personalize recommendations. The novelty of our proposed approach is that it provides personalized recommendations regardless of the research field and regardless of the user's expertise. Using a publicly available dataset, our proposed approach has recorded a significant improvement over other baseline methods in measuring both the overall performance and the ability to return relevant and useful publications at the top of the recommendation list.

  15. Increased Beat-to-Beat Blood Pressure Variability Is Associated With Impaired Cognitive Function
    Asmuje NF, Mat S, Goh CH, Myint PK, Tan MP
    Am J Hypertens, 2022 Dec 08;35(12):998-1005.
    PMID: 36153737 DOI: 10.1093/ajh/hpac107
    BACKGROUND: Emerging evidence has linked visit-to-visit, day-to-day and 24-h ABPM blood pressure variability (BPV) with cognitive impairment. Few studies have, however, considered beat-to-beat BPV. This study, therefore, evaluated the relationship between beat-to-beat BPV and cognitive function among community-dwellers aged 55 years and over.

    METHODS: Data was obtained from the Malaysian Elders Longitudinal Research (MELoR) study, which employed random stratified sampling from three parliamentary constituencies within the Klang Valley. Beat-to-beat blood pressure (BP) was recorded using non-invasive BP monitoring (TaskforceTM, CNSystems). Low frequency (LF), high frequency (HF) and low-to-high frequency (LF:HF) ratio for BPV were derived using fast Fourier transformation. Cognition was evaluated using the Montreal Cognitive Assessment (MoCA) test, and categorized into normal aging, mild impairment and moderate-to-severe impairment.

    RESULTS: Data from 1,140 individuals, mean age (SD) 68.48 (7.23) years, were included. Individuals with moderate-to-severe impairment had higher HF-BPV for systolic (SBP) and diastolic (DBP) blood pressure compared to individuals within the normal aging group [OR (95% CI) = 2.29 (1.62-3.24)] and [OR (95% CI) = 1.80 (1.32-2.45)], while HF-SBPV [OR (95% CI) = 1.41 (1.03-1.93)] but not HF-DBPV was significantly higher with mild impairment compared to normal aging after adjustments for potential confounders. Moderate-to-severe impairment was associated with significantly lower LF:HF-SBPV [OR (95% CI) = 0.29 (0.18-0.47)] and LF:HF-DBPV [OR (95% CI) = 0.49 (0.34-0.72)], while mild impairment was associated with significantly lower LF:HF-SBPV [OR (95% CI) = 0.52 (0.34-0.80)] but not LF:HF-DBPV [OR (95% CI) = 0.81 (0.57-1.17)], compared to normal aging with similar adjustments.

    CONCLUSION: Higher HF-BPV, which indicates parasympathetic activation, and lower LF:HF-BPV, which addresses sympathovagal balance, were observed among individuals with moderate-to-severe cognitive impairment. Future studies should determine whether BPV could be a physiological marker or modifiable risk factor for cognitive decline.

  18. A Competency Framework for Health Research Ethics Educational Programs: Results from a Stakeholder-Driven Mixed-Method Process
    Tackett S, Jenn Ng C, Sugarman J, Daniel EGS, Gopalan N, Tivyashinee, et al.
    Ethics Hum Res, 2023;45(3):29-39.
    PMID: 37167475 DOI: 10.1002/eahr.500166
    Educational programs are integral to building health research ethics (HRE) capacity, but no outcomes framework exists to guide them. We empirically developed a competency framework for health research ethics education-the Framework for Research Ethics Studies Competencies and Outcomes (FRESCO)-using mixed methods, including group concept mapping and a survey of international experts. FRESCO includes seven competency domains: (1) Foundational Knowledge; (2) Laws, Regulations, Guidelines, and Policies for Research Oversight; (3) Ethical-Issue Identification, Analysis, and Resolution; (4) Engagement, Communication, and Advocacy; (5) Lifelong Learning, Education, Research, and Scholarship; (6) Coordination, Stewardship, and Responsiveness in HRE Systems; and (7) Impartiality, Honesty, and Responsibility. These domains are detailed in 27 subdomains. Survey respondents rated FRESCO's relevance to HRE highly. FRESCO can be adapted and implemented in educational programs to refine recruitment and selection processes, educational and assessment methods, and performance measures to ensure that HRE educational programs have their intended effects.
