Authors: Doi Siti Mazura Che , Norwawi Norita Md , Ismail Roesnita , Wahab Mohd Helmy Abd , Idrus Syed Zulkarnain Syed
Published: June 2020

Reservoir water level monitoring is an important process during heavy or light rainfall to determine the volume of reserved water. Mistakes in data recording by the dam operator can lead to disasters. Data from different gauging stations are collected to determine whether to release water in the dam or not. The decision to release water is critical because it can affect the volume of water left in the dam for both drought and flood seasons. Constant water level monitoring is difficult because of the changes in water level. To overcome this issue, intelligent agent-based architecture is proposed for reservoir water level monitoring by imitating the artificial immune system. This paper presents the agent technology where agents communicate with each other concurrently by sending online data from different gauging stations to the main reservoir. One of the techniques in the artificial immune system is known as negative selection and this technique has been chosen as a water level monitoring model.

Internet addiction is defined as one who has no control over his or her desire for internet use. At that time, the internet was a necessity and not a necessity. Family is a unit that shares common experiences, issues and challenges. Thus, the stresses shared by family members are shared. Family stress refers to the imbalance between the demands and the family’s ability to meet those demands. Every family has different experiences and understandings of stress. One of the stress factors in the family is internet addiction. Ignoring the family as a result of internet addiction also affects the emotional, psychological and mental well-being of each family member. The other effects are on the level of communication of each family member, social problems, and developmental stages of the child. There is a link between internet addiction and household stress which includes symptoms, causes and effects that need attention. Every family needs to be aware of this problem and find a solution to it before it gets worse.

Published: June 2020

Students’ perceptions towards mathematics seem to be shaped by how they define mathematics and the role of mathematics in their life. Most students in Malaysia lack experience in dealing with mathematics, thus their achievement in mathematics are not as good as non-Malaysian students (Liew & Pong, 2004). Therefore, the purpose of this study is to investigate students’ perceptions in learning mathematics and how these perceptions may lead to problems in understanding the mathematics itself among students in selected Malaysian secondary schools. A set of questionnaire was distributed to 200 students in Kuantan, Pahang in order to gauge their perceptions in learning mathematics. The researcher also assesses the relationship that exists between students’ perceptions towards mathematics and their academic achievement by using APOS Theory. The respondents generally reported a positive perception towards mathematics. With regard to the correlation analysis, there was a significant statistical relationship between students’ perceptions towards mathematics and their UPSR mathematics grade. However, there was no significant difference between students’ perception towards mathematics and recent mathematics grade. These results warrant further researches using more advanced statistical tools in order to obtain more accurate and relevant findings. Finally it is hoped that the study will open new paths that can benefit mathematics in education system and how mathematics are perceived by students in the classroom.

Published: June 2020

Nowadays the natural slope cuts for the purpose of the construction of public transport is ubiquitous in Malaysia. These cuts cause the changes of the natural slope structure thus make the slope structure become unstable and causes to rubble. In order to avoid the slope’s failure, the monitoring work on slope should be carried out by the responsible party to ensure that the slopes are in good condition and the advance warning can be issued before the occurrence of the rubble. Conventional method of slope monitoring is extremely high risk. Usually, maintenance personnel will climb up to the top of the slope to take pictures for the purpose of monitoring reports [1]. Slope monitoring activities are also limited as climbing steep slope structures require a lot of energy and takes quite a while. Therefore, this research aims to explore the ability of the micro UAV aircraft usage in order to monitor the slope condition. The aim of study is to monitor the high risk slope using UAV. To achieve the aim, the following objectives are formulated by produce orthomosaic image, Digital Terrain Model (DTM) and Digital Surface Model (DSM) using pix4d mapper software, analysis the image of drainage system taken by UAV and developed contour of the slopes and analyse watershed of the slope using global mapper software. In this paper, the drainage on the slope becomes the focus since its plays an important role as it reduces the existence of groundwater and to transport the rainwater pours on slope surface. The study was conducted at two places where first at Kuala Pilah Federal Route 361 and second at Jalan Bangi Selangor State Route B17. The processes involved were planning and preparation before flight, data retrieval using UAV aircraft, image processing using Pix4dmapper software and assessment of the slope using Global Mapper software. Subsequently, the slope condition can be determine based on the monitoring of the slope drainage. Through this study, the condition of slope surface can be seen by images taken from UAV such as cracking on slope structure and excessive vegetation growth in slope drainage. Besides that, the slope inclination, height and water flows on surface can be known.

Published: June 2020

This study proposes a novel technique to convert local iron ores into industrial grade red colour pigments. The methods employed in this work include high-energy milling, ball milling, rod milling and high-energy blending. It was observed in the TEM results that high-energy milling using ø 3 mm balls running at 550 rpm produced the finest particles with a value of 73.13 nm and a specific surface area of 178.62 m2g−1, while ball milling and high-energy blending methods were similarly effective in producing nanoparticles with size of78.54 nm and 88.65 nm, respectively. The sample of high-energy milling at 550 rpm displayed noticeable alterations in colour values, but the lightness of high-energy blending samples was low in comparison to other methods. CIE L*a*b* colour values were analysed for all the samples and the results indicated that the value of a* for all the samples was greater than 18.0. This indicated that the samples are suitable for use as raw materials in red colour pigment production. Generally, the processing speeds utilized by the above mentioned methods resulted in significant changes in colour properties and its microstructure.

This paper proposes a high gain ultra-wideband (UWB) reflector array antenna for cancer detection. Introduction of the copper reflector with ideal distance contribute to increasing the proposed antenna gain. The antenna is printed with 4×1 copper radiating patch array properly connected with quarter wave transformer transmission line associated with a copper parasitic element for the front side. The patches comprise of four identical circulars with a diameter of 15 mm. Parasitic element is placed on very close to feeding line with the gap only 0.2 mm. Each quarter wave transmission line has its own specific wide dimension for 50Ω, 70.71Ω and 100Ω to ensure equal current distribution towards all four patches could be realized. Quarter-wave transformers of 70.71 Ω are used to have an ideal match between the 100 Ω lines and the 50 Ω lines. The high gain antenna is essential in a human microwave detection system for penetrating the multilayer structures by enhancing the focus of the electromagnetic energy into the desired structure. The antenna with reflector recorded wider bandwidth; 1.6 GHz-10.8 GHz associated with higher gain ranged from 3.2 dB until 14.1 dB compared with an antenna without reflector operated from 2.2 GHz to 10.8 GHz with lower gain ranges of 2.1 dB to 10.2 dB.

Teaching is a complicated and comprehensive task. Teachers may spend many years of practice to learn how to teach well, and most of us will not have learned enough. It would be a continuous process to be a good teacher. Instead of keeping on learning what we do not know about teaching the subject, it is better to know what the real problems are happening in the class, reflect what is the cause and come out with an action plan as nobody starts well at teaching. Furthermore, in fulfilling the worldwide demand for Mandarin language acquisition occasioned with the advance affordances of technology, most of the researchers focused on technology impact than the pedagogical aspects. And there is still too little action research regarding teaching pedagogy that has been done on enhancing Mandarin learning, especially in the local context. Thus, it is the right time the researcher cum instructor examines Mandarin pedagogical practice through individual action research to examine to what extent technology-enhanced Mandarin instruction could impact teacher’s pedagogical practice besides assisting students’ learning. A total of fourteen Mandarin non-native learners have participated in the study. The triangulation method was used to ensure the trustworthiness of this qualitative study. The data was collected through students’ diaries, reflective journals, focus group interviews and oral assessment. Then they were analyzed through content and thematic analysis to ascertain the themes regarding teacher pedagogical practice which influenced smartphone usage in Mandarin learning. The results revealed that the human aspect was the most crucial factor in ensuring the success of technology integration instruction. The smartphone was found as a promising tool in teaching Mandarin however it is only effective when teachers use it as a pedagogical tool effectively.

Published: June 2020

Quality of e-service is one of the critical factors that decide the success or failure of organizations. It may increase competitive advantages as well as enhance the relationships with the customers. Achieving high e-service quality and user satisfaction are challenging since they depend fundamentally on user perception and expectation which can be tricky at times. To date, there is no agreement as to what service quality is, and how it should be measured, whether it is a function of statistical measures of quality including physical defects or managerial judgment, or it is a function of customer perception about the services. This paper deep-dived the quality of e-services offered by five Malaysian Institutes of High Learning (IHL) including two private and three public universities. A quantitative approach was utilized to collect the data and AMOS 21 was used to analyze the data and develop the measurement model. The paper aims to find the relationship between e-service quality dimensions and the user satisfaction by using Conformity Factor Analysis (CFA) test with 320 students in the target universities. The research results indicated that the measurement model has acceptable values and the Structural Equation Model (SEM) has positive impact on the relationship between e-SQ dimensions and user satisfaction. Achieving high user satisfaction can enhance the competitive advantage of the universities in their respective target markets.

Authors: Ghazali M.R. , Ahmad M.A. , Raja Ismail R.M.T.
Published: June 2020

This paper presents the design of a data-driven neuroendocrine-PID controller based on adaptive safe experimentation dynamics (ASED) method for a twin-rotor MIMO system (TRMS). Neuroendocrine-PID is deemed a compatible controller, often due to its biological-inspired mechanism from a human’s endocrine system that promotes control effectiveness and accuracy. In assessing the robustness of the proposed controller, its parameters were optimized through the ASED method, by tracking both error and input control performances. In particular, the ASED method is a game-theoretic method that randomly perturbs several elements of its controller parameters to search for the optimal controller parameters. Comparison was further made alongside performance of a standard PID controller. Following the simulation conducted, findings with regards to total norm error and total norm input have hereby suggested neuroendocrine-PID as a better controller, following a 13.2% improvement in control accuracy to that of a standard PID controller for TRMS system.

Authors: Hamidi Z S , Shariff NNM
Published: June 2020

This paper explains the CME phenomena that connect with type II solar burst, focused on the velocity and structure parameters. The data collected were from CALLISTO and LASCO/SOHO satellite for a solar type II radio burst. Radio data presented was from different stations over the world which similarly occurred within 8 minutes to reach the Earth. The drift rate of this solar burst type II is linear to its CME velocity. The majority of type II burst has a drift rate of range 0.05-0.4 MHz/s which is considered as a slow drift rate. Both harmonic and Herringbone structure of type II has a slow drift rate which drifted from high frequency to lower frequency as time duration increases. Slow drift rate was a complement to the solar radio burst type II. Using LASCO data, there was a CME present during the time burst observed. The energy produced during CME phenomena was high enough to associate with burst type II. Herringbone structure of type II burst has variation in its CME velocity and is unpredictable which may have the extreme velocity or much slower velocity. The structure forms a single band which propagates from high frequency to lower frequency in time duration. However, for the harmonic structure of burst type II, the velocity of its associated CME has average speed of 300 to 600 km/s which normally. Thus, the behavior of type II burst needs to be well understood as it associated with the interaction of particles in CME phenomena.

Trust plays a vital role in social commerce due to the inadequacy of physical interaction and experience during the customer-seller transaction. Various studies were drawn in the literature targeting the investigation of the influence criteria related to trust using statistical analysis approach. However, little attention has been paid on the importance of the criteria in evaluating customer trust toward online sellers that used Social Network Sites (SNSs) as business platforms. In this study, the Fuzzy AHP (FAHP) method, an extension of the Analytical Hierarchy Process (AHP) was adopted to determine the importance of criteria in evaluating customer’s trust towards online SNSs sellers. The results of FAHP were then compared against the result of AHP, which both methods’ results similarities and differences were also presented and discussed.

Nitinol is an intermetallic alloy with outstanding properties that suitable as biomaterial. This alloy is capable of recovering to its initial shape after external loading through transformation of the crystalline structure. Unfortunately, excessive exposure of nickel element from this alloy is harmful to human body if released. Thus in this study, the alloy surface was deposited with an oxide layer via electrical discharge coating (EDC) process. The process was performed in deionized water and pure titanium as the electrode. The variation thickness of the recast layer formation was examined by analysing the effects of polarity, gap voltage and erosion depth. Single crater images and electrical waveforms were captured and utilised to elucidate the aforementioned effects. The results exhibited a significant change of layer thickness variation due to different polarity conditions. It was also confirmed that the single crater formation at different polarity was influenced by discharge energy. On other hand, the increase in the open gap voltage can expand the recast layer thickness in lower variation of reverse polarity condition. Finally, erosion depth attributed to a constant layer thickness but in low thickness variation when reverse polarity was employed.

Ineffective cognitive processes result in learning difficulties online. Hence, how cognitive learning processes influence the way students engage and learn online needs further investigation. This study, therefore, examined cognitive engagement and metacognitive knowledge strategies on learning performance among Malaysian IT Undergraduates. A sample of 563 IT undergraduates from private higher education in Malaysia participated in this quantitative study that were collected through a questionnaire. Data was analysed using PLS-SEM. The findings of this study constitutes essential results where all cognitive engagement strategies and two of metacognitive knowledge strategies positively influence the students’ perception of learning performance. Nevertheless, one metacognitive strategy resulted in a negative relationship with learning performance which have led to a new finding. This study concluded that the acquisition of cognitive and metacognitive skills are needed to excel in digital learning for deeper learning. Lecturers can use the findings of this study to integrate the necessary cognitive and metacognitive learning approaches across all key learning areas in the digital learning without altering the curriculum.

Flood is the most frequent disaster in the world. The impact of floods is very large, like human and animal death, the villages vanished and other environments damaged. In disaster preparedness, it is very necessary to divide the stages of the disaster status level. Therefore the public can prepare themselves according to these stages. The stage of disaster preparedness status is also beneficial for the government and related institutions to act according to the status stage of the disaster. This paper will propose the early warning system for flood disaster based on fuzzy logic in IoT system. This algorithm was built 8 rules. The inputs are the rainfall and height of water. The output is the status of flood disaster. The types of disaster status are normal, moderate 1, moderate 2, emergency 1, and emergency 2. From the simulation result, it is concluded that this fuzzy logic model can to determine the status of flood disaster very well.

The fourth industrial revolution (IR 4.0) is built upon the digital revolution where technology and people are connected. It does not just present modern techniques for supporting aspects within industry but cover as well the sustainability. Thus, it is very important for electric and electronic (E&E) industry to develop a new technique for a better quality evaluation of product. The aim of this work is to apply Mahalanobis-Taguchi System (MTS) in production environment at E&E industry for a better quality evaluation. MTS is used to classify normal and abnormal observations and optimize various parameters in workstation to produce a better quality product. This work found that positive gain through signal to ratio (SNR) indicated the quality of system still in good condition from February with 0.1244 until December with 0.4432 after insignificant variable have been removed. This work also suggested condition of core should be removed since the variable does not contribute to the system along 2018. Meanwhile, some variables are showed inconsistency of significant to the system such as wire condition, epoxy condition, lead part condition and soldering condition. This concluded that MTS is a practical method for classification and optimization in the industry.

The study explores the uses of gadgets to assist young learners in their quest for learning. More specifically, the aims of the current study are to identify the gadgets that are used among children for learning purposes, hours they spend in using the gadgets, rules that are being implemented by parents for the uses of gadgets, benefits gain by children in the uses of the gadgets and parents’ expectations of the uses of the gadgets for learning purposes. The study that employs qualitative research among six respondents found that smartphones, tablets and computers were among the gadgets that were used by the children when parents permitted them to use the tools on average for three hours. It was also observed that some parents were rigid while some were lenient setting rules for their children to use the gadgets. Various perceived benefits were also demonstrated among parents. In terms of expectations, parents demonstrated some hope that the uses of the gadgets among their children would make the latter able to learn language, mathematics and social skills; to name a few. The study implies that parents need to control the uses of gadgets among their children even though the tools are used for learning purposes.

To date, frequent seismic events are seen to cause major destruction to the countries that are hit by great Earthquake with magnitude greater than 7 Scale Richter. These kinds of disasters are unpredicted and may give negative impacts for structures and human. However, the consequences of seismic can be mitigated by characterizing the hazard that might be affecting the existing structures. Therefore, the performance of tunnel form building (TFB) has been examined under various level of earthquake events. Ten numbers of ground motions are selected based on previous earthquake records to determine the level of safety of single unit tunnel form building (TFB). Four previous earthquake records are selected from countries outside of Malaysia, while the other six previous earthquake records are selected from East and West Malaysia. The prototype building has then been modelled and analysed to obtain the maximum lateral displacement and lateral loading capacity to assess the structural deformation of the TFB at peak ground acceleration for selected past earthquake history. From this analysis, the safety level of TFB under selected ten past earthquake records are investigated. It can be concluded that this type of building survives under local earthquakes but experienced severe damage or collapse under major earthquakes deriving from countries outside of Malaysia.
Uncorrelated Discriminant Projection Based on Maximum Margin Criterion and Its Kernelized Extension
Authors: Amin Muhammad , Ahmad Noor Atinah
Published: June 2020

A new linear dimensionality reduction algorithm called uncorrelated discriminant projection (UDP) is proposed in this paper. The proposed UDP algorithm is based on the maximum margin criterion (MMC) which aim at maximizing class separation after dimension reduction. By imposing an uncorrelated constraint in the objective function, UDP extracts statistically uncorrelated features which are important in many pattern recognition problems. Moreover, we propose performing UDP in reproducing kernel Hilbert space (RKHS) which leads to a nonlinear variant of UDP called kernel uncorrelated discriminant projections (KUDP). In order to demonstrate the effectiveness and efficiency of the newly proposed algorithms, we conducted experiments on two benchmark face databases. The experimental results indicates that both UDP and KUDP are able to find face subspaces optimal for recognition.
