Development of chitosan/pluronic F108/polyethersulfone (PES) nanofiltration (NF) membrane for oily wastewater treatment
No full textThis study discusses a new finding for nanofiltration membrane development using phase inversion
technique whereby polyethersulfone (PES) polymer was added with surfactant and additive. This
research focuses on the development of a membrane that is efficient in treating oily wastewater and
reducing membrane's low permeation flux issues. Five PES nanofiltration membranes were
synthesized with pluronic F108 surfactant and different amounts of chitosan additive for each
formulation. Subsequently, the effect of adding surfactant and additive on membrane performance
was studied. Results showed that the membrane with the optimal amount of chitosan gave the
highest flux and the rejection of oily wastewater with up to 90%. In addition, Fourier transforminfrared (FTIR) spectroscopy technique was used to characterize and analyse the membrane's
properties. Hence, the developed membranes were successfully characterized and proved to be a
good treatment for oily wastewater
The employment of support vector machine to classify high and low performance archers based on bio-physiological variables
No full textThe present study employs a machine learning algorithm namely support vector machine (SVM) to classify high and
low potential archers from a collection of biophysiological variables trained on different SVMs. 50 youth archers with
the average age and standard deviation of (17.0 +/-.056) gathered from various archery programmes completed a one
end shooting score test. The bio-physiological variables namely resting heart rate, resting respiratory rate, resting
diastolic blood pressure, resting systolic blood pressure, as well as calories intake, were measured prior to their
shooting tests. k-means cluster analysis was applied to cluster the archers based on their scores on variables
assessed. SVM models i.e. linear, quadratic and cubic kernel functions, were trained on the aforementioned variables.
The k-means clustered the archers into high (HPA) and low potential archers (LPA), respectively. It was demonstrated
that the linear SVM exhibited good accuracy with a classification accuracy of 94% in comparison the other tested
models. The findings of this investigation can be valuable to coaches and sports managers to recognise high potential
athletes from the selected bio-physiological variables examined
The application of k-Nearest Neighbour in the identification of high potential archers based on relative psychological coping skills variables
No full textThe present study aims at classifying and predicting high and low potential archers from a collection of psychological
coping skills variables trained on different k-Nearest Neighbour (k-NN) kernels. 50 youth archers with the average age
and standard deviation of (17.0 +/-.056) gathered from various archery programmes completed a one end shooting
score test. Psychological coping skills inventory which evaluates the archers level of related coping skills were filled
out by the archers prior to their shooting tests. k-means cluster analysis was applied to cluster the archers based on
their scores on variables assessed k-NN models, i.e. fine, medium, coarse, cosine, cubic and weighted kernel
functions, were trained on the psychological variables. The k-means clustered the archers into high psychologically
prepared archers (HPPA) and low psychologically prepared archers (LPPA), respectively. It was demonstrated that the
cosine k-NN model exhibited good accuracy and precision throughout the exercise with an accuracy of 94% and
considerably fewer error rate for the prediction of the HPPA and the LPPA as compared to the rest of the models. The
findings of this investigation can be valuable to coaches and sports managers to recognise high potential athletes
from the selected psychological coping skills variables examined which would consequently save time and energy
during talent identification and development programme
Solar radio burst in National Space Agency of Malaysia (ANGKASA)
No full textThe sun is an active star that produces large-scale energetic events, such as solar flares
and coronal mass ejections (CMEs). These phenomena are observable across the electromagnetic
spectrum, from gamma rays at hundreds of MeV to radio waves with wavelengths of tens of
metres. Solar flares and CMEs can excite plasma oscillations which can emit radiation at metric
and decametric wavelengths. These radio bursts are classified in five main types. This paper
gives a solar radio burst type III (16 July 2017) in National Space Agency (ANGKASA),
Banting, Selangor, Malaysia. Compact Astronomical Low-Cost Instrument for Spectroscopy in
Transportable Observatories (CALLISTO) is used in this system to observe solar radio activities.
The main applications for this CALLISTO is to observe a solar radio bursts and radio frequency
interference (RFI) monitoring for astronomical science, education and outreach. The CALLISTO
natively operates between 45MHz to 870MHz and its observed daily
Wavelet-based auto-counting tool of aedes eggs
No full textAedes aegypti mosquito species are an important vector of many viruses including dengue and Zika. Preventing or
reducing the virus transmission depends entirely on controlling the mosquito vectors. To facilitate a vector control
operation, a new image processing tool is developed for counting Aedes eggs so that fecundity estimation can be
done automatically replacing the manual counting that requires a lot of efforts and time-consuming. The proposed
tool is based on Gabor wavelets to produce a response map that can ease the thresholding process. We test the
proposed tool of Aedes eggs counting by comparing with ICount and EggCounter which is freely available on the
Internet. The results showed that the proposed method is promising for a reliable estimation of Aedes eggs

Interrogation of children in conflict with the law: A comparative analysis between Malaysian law and the international standards
No full textInterrogation is considered as one of the crucial stages of juvenile justice process. During the process of interrogation, any suspected child may be subjected to various modes of questioning, interview and examination with a purpose to obtain evidence and confession for an alleged crime. While this process undeniably important aspect of criminal process aims to maintain public order and justice, it may turn out to be a terrifying event for children, who are known for their physical and emotional vulnerability. This paper aims to comparatively analyse between Malaysian current law and practice an interrogation of children and the international standards set by the international instruments. It attempt to examine to what extent current Malaysian law on interrogation measure up with the recommendation for the reform of current Malaysian law on interrogation measure up with the requirements of international standards. This article concludes with the recommendation for the reform of current Malaysian law and practices on interrogation of children
The adoption of social learning systems in higher education: Extended TAM
No full textThis study adopts the Technology Acceptance model (TAM) to identify the successful factors that influence student's
intention to use social network learning system. The TAM proposed by Davis was the theoretical basis of the research.
The researcher then extended TAM incorporating (self-efficacy, facilitating conditions, technology awareness,
computer and internet training, social norm and information quality) to identify the successful factors effecting the
student's intention to use social network learning system. Results of this study found that Information Quality (IQ) is
the most influential factor on student's intention to use social learning system, followed by Perceived Usefulness (PU),
and Facilitating Condition (FC) respectively
A new beginning of trauma theory in literature
No full textCathy Caruth's Unclaimed Experience: Trauma, Narrative, and History and Kali Tal's Worlds of Hurt: Reading the
Literatures of Trauma sparked a great attention to literature lovers. Her suggestion on Trauma Theory enlightens a
new era in poststructral approach of analyzing literary texts. Slowly but gradually, several models were introduced
which inherent neurobiological features of trauma that refuse representation and cause dissociation were significant
to arguments that sought to emphasize the extent of profound suffering from an external source, whether that source
is an individual perpetrator or collective social practice. It was quickly accompanied by alternative models and
methodologies that revised this foundational claim to suggest determinate value exists in traumatic experience.
However, the researcher would like to explore and reintroduce Trauma Theory in more contemporary approach so
that it will be acceptable and practical in all genres of literature. Similarly, this study is in line with the critics such as
Leys and Cvetkovich who establish a psychological framework apart from the classic model thus produce different
conclusions regarding trauma's influence upon language, perception, and society. The researcher believes that
Trauma Theory should be viewed in a larger conceptual framework rather than the social psychology theories in
addition to neurobiological theories; that is in the view of Critical Thinking. This stance might therefore consider
dubious the assertion of trauma's intrinsic dissociation. The discussion focuses more on the roles of Critical Thinking
in supporting Trauma Theory in several selected poems. In conclusion, the findings might prove that Critical Thinking
and Trauma Theory can be blended together in developing learners' intellectuality and maturity in analyzing and
appreciating literary texts
The perspectives of a higher education provider and member of malaysian qualifications agency panel of assessors on the external examining system
No full textExternal examiners were required for bachelor-level academic programmes and beyond according to the Malaysian Qualifications Framework. Matters pertaining to external examining can be found in Guidelines to Good Practices Monitoring, Reviewing and Continually Improving Institutional Quality that was published by the Malaysian Qualifications Agency (MQA). There were inherent issues and challenges associated with the system’s implementation such as meeting quality expectation and developing indicators of external examining, variability in practices, anxieties about the potential for 'cosy' relationships between examiners and departments, and clarity and authority in examiners’ role in assuring standard. An exploratory research was conducted to understand the issues. Five groups of respondents were interviewed. They were higher education providers’ officers responsible for Continuous Quality Improvement (CQI), members of private higher education institution representative bodies, members of professional bodies, and government officers responsible for quality in higher education. Preliminary results suggested that there were evidences of general principles, expectation, and indicators of sound practice of external examining in Malaysia’s HEPs
