Azharudin Mukhtaruddin, Muzamir Isa, Mohd Fadzil Ain, Mazlee Mohd Noor, Mohd Rafi Adzman, Mohamad Nur Khairul Hafizi Rohani

 

Abstract

Partial discharge (PD) is a phenomenon that may lead to dielectric breakdown and can provide important information for condition monitoring on electrical power equipment, in particular transformer. One of the methods is the detection of the electromagnetic (EM) wave signal emitted by PD. Although the frequency spectrum in EM is very wide, this paper discusses the detection of EM only at ultra-high frequency (UHF). One of the detectors that can be used to detect EM is the antenna. There are a lot of antenna designs that have been proposed to detect the signal. The designs can be generally divided into two: PCB-based design and physical antenna design. An example of the latter is monopole. Some of the proposed antennas were left at the design stage while others went to be applied in actual PD experimentation. Discussion on the capabilities of these antennas can lead to the selection of a suitable antenna.


PATH FINDING OF STATIC INDOOR MOBILE ROBOT VIA AOR ITERATIVE METHOD USING HARMONIC POTENTIALS

A'qilah Ahmad Dahalan, Azali Saudi, Jumat Sulaiman 

 

Abstract

Mobile robots often have to discover a path of collision-free towards a specific goal point in their environment. We are trying to resolve the mobile robot problem iteratively by means of numerical technique. It is built on a method of potential field that count on the use of Laplace’s equation in the mobile robot’s configuration space to constrain/which reduces the generation of a potential function over regions. This paper proposed an iterative approach in solving robot path finding problem known as Accelerated Over-Relaxation (AOR). The experiment shows that these suggested approach can establish a smooth path between the starting and goal points by engaging with a finite-difference technique. The simulation results also show that a more rapidly solution with smoother path than the previous work is achieved via this numerical approach.

Abstract

Kesedaran terhadap bunyi bising di tempat kerja sememangnya semakin meningkat. Di pengkalan No. 11 Skuadron serta bangunan bersebelahan dengannya, pesawat Sukhoi merupakan punca utama bunyi bising atau hingar yang memberi kesan kepada pekerja dan orang awam. Objektif kajian ini adalah untuk menentukan kadar bunyi yang dihasilkan oleh pesawat Sukhoi ketika operasi penyelenggaraan. Pesawat Sukhoi mempunyai dua enjin yang merupakan punca bunyi bising di lapangan ini. Kajian ini dijalankan dengan menggunakan alat pengukur bunyi mudah alih Bruel & Kjaer 2250 yang diletakkan di tengah-tengah pesawat di dalam hangar untuk mengukur bunyi pada jarak 10 meter, 50 meter, 100 meter, 500 meter, 1000 meter dan 1500 meter. Enjin pesawat tersebut beroperasi pada dua tahap, 72% RPM dan kemudiannya pada 85% RPM. Pada setiap jarak, golongan yang terdedah berbeza di mana orang awam hanya terlibat bermula dari jarak 1000 meter dan ke atas. Pekerja TUDM dan pekerja yang terlibat dengan penyelenggaraan pesawat tersebut terdedah dengan bunyi bermula dari jarak 0 meter lagi (yakni berada dibawah enjin pesawat). Data yang diperoleh dianalisa untuk menghasilkan peta hingar dan kontur hingar. Hasil daripada lakaran tersebut, tahap pendedahan hingar dapat dikenalpasti. Bunyi maksima yang telah direkodkan adalah 122 db(A) manakala yang terendah adalah 60 dB(A). Kadar bunyi yang direkodkan semakin rendah apabila jarak dari punca bunyi bertambah. Dari peta lakaran tersebut, kesan pendedahan terhadap kedua-dua pekerja dan orang awam dapat dikenalpasti. Walaupun pendedahan selama 5-10 minit sahaja setiap kali ia berlaku, tetapi ia tetap menjengkelkan (annoyance) dan untuk jangka masa panjang ia tetap dapat mengancam kesihatan mereka yang terlibat.

 

 Awareness of occupational noise and its effects is growing. At No. 11 squadron base, Sukhoi jet was identified as the main culprit of occupational noise that affects not just the employees of the base but also civilian people in the surrounding area. The objective of the study is to identify the noise level produced by Sukhoi two-engines jet during maintenance operations. Investigations were carried out using Bruel & Kjaer 2250 sound level meter hand-analyser. Measurements were performed directly under the Sukhoi jet body and then 10 metres, 50 metres, 100 metres, 1000 metres and 1500 metres away. The jet engines could operate at two levels, at 72% RPM and at 85% RPM. The civilians are only exposed to its noise from more than 1000 metres away. The results from this study are analysed and noise mapping and noise contouring are produced which give the level of noise exposure. The maximum noise is recorded t 122dB(A) and the minimum is at 60dB(A). The farther the noise from the jet is measured, the lower the values recorded. From the noise mapping, the effects of noise exposures on both the employees at the base and the civilian at the neighbouring surrounding could be identified. Even though the exposures are only for 5-10 minutes, it is still considered as a threat.

Siti Rohaidah Ahmad, Nurhafizah Moziyana Mohd Yusof, Siti Hajar Zainal Rashid, Abdul Ghapor Hussin 

 

Abstract

Assessment of instructors by students is needed for assessing the teaching quality of a lecturer towards achieving the objectives of a course. This paper aims to examine the techniques used in sentiment analysis for assessing the effectiveness of a lecturer’s or a teacher’s teaching style in the learning process at a university or school. In addition, the effectiveness of sentiment analysis techniques in assisting the teaching evaluation process is also discussed. The challenges for assessing the quality of teaching of National Defence University of Malaysia (UPNM) lecturers are also discussed in this paper. The sentiment analysis technology is capable of analysing views or opinions on a matter, regardless of whether they are positive or negative. Data from the sentiment analysis can be used by specific parties or anyone else to rectify any weakness or to improve any aspect that the user commented on. The purpose of this study is not to find the weakness of the lecturer, but rather the results of this assessment process can be useful to the management for rectifying weaknesses and for improving the teaching process.

Nurhafizah Moziyana Mohd Yusop, Nooraida Samsudin, Anis Shahida Mokhtar, Siti Rohaidah Ahmad, Aslina Baharum, Mohd Fahmi Mohammad Amran 

 

Abstract

Euler method is a numerical order process for solving problems with the Ordinary Differential Equation (ODE). It is a fast and easy way. While Euler offers a simple procedure for solving ODEs, problems such as complexity, processing time and accuracy have driven others to use more sophisticated methods. Improvements to the Euler method have attracted much attention resulting in numerous modified Euler methods. This paper proposes Cube Polygon, a modified Euler method with improved accuracy and complexity. In order to demonstrate the accuracy and easy implementation of the proposed method, several examples are presented. Cube Polygon’s performance was compared to Polygon’s scheme and evaluated against exact solutions using SCILAB. Results indicate that not only Cube Polygon has produced solutions that are close to identical solutions for small step sizes, but also for higher step sizes, thus generating more accurate results and decrease complexity. Also known in this paper is the general of the RL circuit due to the ODE problem.

Abstract

Privacy has always been a constant concern for many people. Internet users are often worried about the browsing information that is left on their storage media. Web browsers were later introduced with a new feature called private browsing to overcome this issue. The private browsing mode is expected to behave as normal browsing session but without storing any data such as browser cookies, history, cache and passwords on the local machine. Unfortunately, previous researchers concluded web browser often failed to provide the intended privacy protection to their user. Along the way of this reviewing process, the weakness and downside of previous web browser vendors have been identified

Muhammad Nur Arsyad Azman, Choy Peng Ng, Faridah Hanim Khairuddin, Neza Ismail, Wan Mohamed Syafuan Wan Sabri

 

Abstract

Road surface condition of a pavement is one of the most important pavements features as it affects the dynamic load of vehicles travelling on it, the quality of travel and the vehicle operating cost. It is important to maintain a good road surface condition in order to promote safety and to reduce traffic accidents and injuries. The Composite Pavement Performance Index (CPPI) is one of the important tool to measure the performance or condition of a pavement. By conducting pavement evaluation using the CPPI, civil engineers could prioritize the maintenance and rehabilitation which usually incurred a huge cost. In University Pertahanan Nasional Malaysia (UPNM), there is no proper maintenance and rehabilitation scheduled for the roads as there is no performance evaluation tool available to measure the pavement performance or condition. Thus, the objective of this study is to develop a Composite Pavement Performance Index (CPPI) to monitor the pavement condition and to rank the roads in UPNM. In order to develop the CPPI, road defects data were collected from 6 internal roads in UPNM. From the data collected, 4 major types of distresses: rutting, pothole, crocodile cracking and longitudinal cracking are more likely to occur on the pavements in UPNM. By measuring the growth of the distresses over a period of 6 months, the CPPI was developed to rank the roads in UPNM. Using the CPPI, this study demonstrated that the road connecting to the library building experienced the worst pavement deterioration in UPNM with a value of CPPI of 24. The condition of the pavement was classified as poor. Thus, it is recommended that the road connecting to the library building should be reconstructed to increase the safety for road users.

Abstract

During a disaster, the rescuer must reach the disaster area within the fastest time with the help of navigation tools. However, there might be some obstacles during the night time that make the evacuation of the victims difficult especially due to the bad weather. Hence, an attempt to produce glow-in-the-dark emergency signage to ease the evacuation process and to enhance visibility during night time is necessary. In this present study, particular emphasis is given to investigate the characteristic of photo-luminescent (PL)powder applied with polyester resin as glow-in-the-dark emergency signage. Five samples of signage were fabricated with different percentage of PL powder, i.e. 20%, 40%. 60%, 80% and 100% and mixed with 150g polyester resin. Three types of luminance test were performed to check the workability of the samples. The tests are physical appearance, one-hours illuminance test and afterglow duration tests. The result showed that the maximum lux meter reading was recorded in Sample 5 with 6 lux luminosity and provided the longest glow duration of the sample before completely off after 12-hours. Results proved that the highest percentage of the PL powder content, the longer the afterglow duration will be achieved. It also noted that the polyester resin could be a good binder of PL powder for producing the glow-in-the-dark emergency signage.

Suzaimah Ramli, Tuan Khalisah Tan Zizi @ Tuan Zizi, Norulzahrah Mohd Zainudin, Nor Asiakin Hasbullah, Norshariah Abdul Wahab, Noor Afiza Mat Razali, Norazlin Ibrahim

 

Abstract

Thermal imaging technology can be used to detect aggressive levels in humans based on the radiated heat from their face and body. Previous researches have proposed an approach to figure out human aggressive movements using Horn-Schunck optical flow algorithm in order to find the flow vector for all video frames but still not strong enough to confirm and verify the existence of an aggressive movement. In this work, we propose an approach by using thermal videos for frontal views of the human body which is face view. Then, video frames are collected using thermal camera and further extracted into thermal images. We use thermal imaging to monitor the face including prefrontal and periorbital region’s thermal variations and test whether it can offer a discriminative signature for detecting aggressiveness. We start by presenting an overview of 3400 thermal images extracted from 50 participants. The results obtained is promising where aggressive and non-aggressive features can be detected by using color-based approach.

Abstract

The purpose of the study is to determine the optimal condition for mixing factors of natural cellulose or epoxy composite by using response surface method. Three mixing factors selected for the study were degassing agent content, stirring time, and sonication time. As a response, the fracture toughness of the composites was determined by using single edge notch bending test. The level of each factor was selected at 3 conditions which were low, medium, and high. The analysis of variance showed degassing agent content and sonication time were the most significant factors affecting the fracture toughness of the composite. The optimal conditions for mixing factors were 1.34 wt% degassing agent content, 5 minutes for stirring time, and 60 minutes for sonication time. The predicted fracture toughness was 1.6836 MPa.m0.5 with a desirability value of one. Three validation experiments were conducted to test the generated mathematical model and results showed the percentage difference was in the range of 6% to 15%.

Abstract

Inappropriate use of antibiotics (AB) is a significant public health problem. Understanding the patterns of AB-taking behaviour helps in designing educational campaigns to curb the overuse of AB. The objective of this study was to determine the levels of knowledge, attitudes and practices (KAP) of AB usage among students and staff at the National Defence University of Malaysia. This cross-sectional study was conducted in July 2018. A self-administered questionnaire was used. Data were described by frequencies and percentages. Chi-square test was used to compare KAP levels between students and staff. The level of significance was established as p ≤ 0.05. This study revealed that fair level of knowledge about AB usage did not translate into positive attitudes and high levels of practices. Overall, students demonstrated poorer KAP regarding indiscriminate usage of AB than staff. Specifically, students had poorer knowledge about its role in ineffectiveness of treatment (p=0.013) and additional burden of medical cost to the patient (p=0.001). Additionally, students were more likely than staff to give the leftover AB to their friends if they become sick (p=0.024). The findings of this study may serve as a preliminary insight on the development of an effective intervention to improve attitudes and practices regarding AB usage.

 

TOWARDS THE DATA SECURITY AND DIGITAL EVIDENCE BASED SOLUTION IN BANGLADESH PERSPECTIVE

Shekh Abdullah-Al-Musa Ahmed, Nik Zulkarnaen Khidzir, Tan Tse Guan 

 

Abstract

Data is anything in a form suitable for use with a computer. Data is often distinguished from programs. A program is a set of instructions that detail a task for the computer to perform. In this sense, data is thus everything that is not program code. Generally and in science, data is a gathered body of facts. Data security refers to protective digital privacy measures that are applied to prevent unauthorized access to computers data. Data security also protects data from corruption. However in this article would show a method for encryption text data by java program. It will encrypt is such a way that data could not read in plain text. Whereas Forensic science is a combine science. Scientific Evidence is a part of forensic science. By using the forensic science collecting information and present it on the court. So the meaning of evidence of science representing the understanding of collection information by establishes science. For example to create a DNA profile, following the establish protocol to make a DNA profile. So by testing it thousand times it will give the same result. This is the establish rule of science. When applying this rule in the court then it will call scientific Evidence. In Bangladesh most of the time it is seen that judiciary process is depends on confession based. Justice in the lower court does not depend on Digital forensic rather depend on Confession based. The definition of document is given in Section 3 at Evidence Act, 1872 and it is amended by ICT Act 2006 by Section 87 ,it is said that creating document by electronic is also a document .So any picture or video or audio are electronic document is a document .However for digital evidence based solution in this project using autopsy forensic tools, which will run on Kali Linux Forensic mode. It will generate a report paper and calculates MD5 hash values and confirms the integrity of the data before closing the files. Not all computer offence we can called cybercrime , but if a person created forged certificate or steal computer file , may called it as a Digital Crime .In real space , there are some physical force such as robbery , theft etc. But in Digital crime, there is no physical force, but doing the crime by technology.

Syarifah Bahiyah Rahayu, Nur Diyana Kamarudin, Afiqah Mohammad Azahari, Arniyati Ahmad, Mohd Hazali Mohamed Halip

 

Abstract

An average number of books for a normal library is around 10,000. Finding books in a library is a cumbersome process and time consuming especially in a huge library. Besides, the cost to embed RFID tag on each book is too expensive. To overcome the problem, this paper proposed a solution for finding location of library books. The solution is using i) a smartphone application to navigate location of book, and ii) LED Blinker with Beacon Bluetooth Low Energy (BLE) technology on bookshelf. The case study for this research is Library of Jeneral Tun Ibrahim at Universiti Pertahanan Nasional Malaysia (UPNM) Library. This study also produces a new framework for finding books in libraries. The framework is a proof of concept that can be applied in the smart library system to assists library patrons in finding locations of books.

Ahmad Salihin Ahmad Shukeri, Nur Diyana Kamarudin, Siti Noormiza Makhtar, Syarifah Bahiyah Rahayu, Suzaimah Ramli

 

Abstract

This paper represents an effective method to enhance colour correction for tongue diagnosis. Colour Correction means exactly that, correcting the colour in image in the post production process. If the task of correcting an image is not in the workflow, it may be missing out on how great the image could look. It is one of the tasks of being a director of photography to get the best image to the colourist that can be. Understanding the camera’s limitation and using that knowledge on set is the first step in getting images that are much easier to correct later in the production workflow. Cameras record three colour responses of Red, Green and Blue (RGB) that are device dependent. In this work, preliminary research on tongue colour correction using polynomial regression algorithm has been implemented on Munsell colour checker for future tongue colour correction and diagnosis. The attained RGB colour space from Munsell Checker image converted to Lab colour space which is device independent colour space based on human visual system that is perceptually uniform. Then, several degrees of polynomial regression method are employed to provide comparative analysis on colour reproduction index to produce good quality of image after colour correction procedure. The experimental outcomes on colour checker show the colour difference is equal to 3.3289, ∆E*ab=3.3289 which is acceptable in digital image colour reproducibility.

 

 

PROTOTYPING DIGITAL TONGUE DIAGNOSIS SYSTEM ON ROBOREALM AND RASPBERRY-PI

Muhamad Hafiq Subandi, Nur Diyana Kamarudin, Muhammad Azrae Yusof, Azrena Abu Bakar

 

Abstract

In Oriental Medicine, the examination of tongue body contributes to rich information in diagnosing some diseases. The practitioners use tongue body colour and other relevant features to predict the patient’s conditions and disease-oriented state. To reduce the ambiguity and other limitation caused by environment, an automatic tongue acquisition system has been introduced recently to assist the medical practitioner in daily clinical practices. However, most of these acquisition systems are not equipped with the intelligent decision support system to diagnose certain diseases using informative tongue bio-markers. In this paper, automatic tongue diagnosis prototype on Raspberry-pi is proposed to reduce human labour and to promote portability. To integrate with Internet of Things (IOT) technology, tongue image processing analysis including segmentation and colour classification techniques using k-means and Support Vector Machine (SVM) is executed on Raspberry-Pi that is equipped with High Definition (HD) camera via MATLAB Coder platform. This high definition camera will capture the real time image of a patient’s tongue to be segmented and analysed further. It is expected to provide health information that can be used as a pre-diagnosis system based on Oriental Medicine perspectives.

 

 

ASSESSMENT OF KNOWLEDGE AND ATTITUDE REGARDING HUMAN PAPILLOMA VIRUS VACCINATION AMONG PRECLINICAL MEDICAL STUDENTS IN THE MALAYSIAN MILITARY UNIVERSITY

Aye Aye Mon, Halyna Lugova, Myint Myint Maw

 

Abstract

Human papillomavirus (HPV) causes cervical cancer and sexually transmitted infections. Cervical cancer is the third most common malignancy among the women worldwide. The primary tool for prevention of cervical cancer is through the HPV vaccination. Pre-clinical year medical students must have background knowledge about HPV vaccination as they become healthcare providers, who will play an important role in influencing patients’ decision to receive vaccination. If their knowledge on the HPV is low this will result in poor attitude towards its prevention. This study was aimed to determine the knowledge of HPV vaccine and cervical cancer as well as the acceptance of HPV vaccination among pre-clinical year medical students. A descriptive cross sectional study was conducted among 83 pre-clinical year medical students in National Defence University of Malaysia (NDUM). A set of self-administered questionnaire was distributed to the respondents to gather the data. Although almost half of respondents (46.3%) did not know the exact indication for HPV vaccination Most of them perceived that HPV vaccine can protect against the cervical cancer (64.4%) and it is as important as Hepatitis B or Haemophilus influenzae vaccines in Malaysia (54.9%). Substantial proportion of the respondents (47.6%) disagreed that HPV vaccination will diminish the need for annual Pap smear testing. The findings of this study show that being a pre-clinical year student does not warrant good knowledge and prevention of HPV infection. There is a need to obtain more information about HPV vaccination effects on cervical cancer in their medical school teaching and from the social media.
