This study tries to develop Computer and Network Asset Manager (CNAM) that is a network management application which helps large enterprises, and Small medium enterprises (SMEs) service providers, manage their data centers and IT infrastructure efficiently and cost effectively. CANM collects information on all hardware components of the network instruments that are on the network. In this project, a real-time network monitoring method is suggested for dynamic information to reduce the complexity and cost based on network management. In the proposed method, a Simple Network Management Protocol (SNMP) is first used to collect data for start interaction between equipment in the specific data center, to gather these data SNMP would need to request it from Management Information Base (MIB) that served as a database for stored information. Furthermore, to ensure data authenticity in the management station that fetches real-time data periodically from equipment, network engineer would have to manually key-in static information into CNAM when it was first launched. The SNMP would then pick up on this stored static information and automatically began collecting real-time data; this feature will be developed with the help of Model View Controller (MVC) pattern that is a software pattern for implementing user interfaces. It allows users to have interaction with the CNAM as well as input the related data. The object oriented approach shall be used to implement SNMP and MIB which represents system management information. Web Based Enterprise Management (WBEM) is required in order to transfer protocol like SNMP, as well as to enter the actual data manually for further authenticity with the real time data. This study would hopefully encourage companies to try an interactive solution for problem in managing their equipment in the data center. N002 (1570020433) Current Developments in LTE-ADVANCED: Radio Resource Management Review Mohd Khairy Ismail; Muhammad Syahrir Johal; Azmi Awang Md Isa This paper provides a review of current technology components currently used by OFDMA-based Long Term Evolution-Advanced (LTE-Advanced). LTE- Advanced significantly enhanced the previous versions of LTE Release 8/9 to support higher data rates and wider coverage resulting in best experience for users. Some of the technologies discussed in this paper are enhanced Multiple Input Multiple Output (MIMO), advanced repeaters or known as relaying systems, coordinated multipoint transmission/reception and carrier aggregation to expand the capability of the bandwidth spectrum. Among the issues addressed in this paper are related to balancing of transmit power control for both base stations and relay stations and also frequency spectrum allocation in order to avoid any interference within a mobile cell. This also includes how to manage different types of interferences such as intercell interference, intersymbol and intercarrier interferences in the LTE-Advanced system. N003 (1570021009) The Impact of Mobility Models on Nodes Cooperation in Mobile Ad Hoc Networks Nor Effendy Othman; Rosilah Hassan; Samer Sami Hasan In mobile ad hoc networks (MANETs), nodes usually have limited radio power and transmit in a very limited area. Communication beyond a node’s radio range requires multiple hops between nodes, which in turn, requires nodes in MANETs to cooperate with each other in forwarding packets from a source to a destination. Problems in cooperation arise in self-organizing MANETs where selfish nodes exist. Selfish nodes are reluctant to forward other nodes’ packets in order to save their limited resources for their own use. Thus selfish nodes can prevent multi-hop communication in MANETs. Many previous studies have worked on the problem of nodes cooperation and selfish nodes. However, it is not clear how the choice of mobility models in simulation studies affects the evaluation of the cooperation of nodes. While most studies employ a random waypoint mobility model, it is questionable if this model reflects realistic movement and thus may be cause for unrealistic results. In this paper, we investigate the impact of mobility models on the cooperation problem. Our results show that Random Waypoint Mobility and Steady-state Random Waypoint Mobility models have a similar impact on nodes cooperation while Self Similar Least Action Walk Mobility model differs significantly than the two models. N004 (1570025721) Mobile Cloud Computing & Mobile Battery Augmentation Techniques: A Survey Mushtaq Ali; Jasni Mohamad Zain; Mohamad Fadli Zolkipli; Gran Badshah Energy efficiency of mobile devices is paramount after the tremendous advancement in technology while the explosion of smart mobile applications such as, YouTube, Facebook, Twitters and Google maps makes Smart Internet Devices (SIDs) the first choice of communication. On the other hand, multiple sensors and wireless interfaces drain battery swiftly, thus reducing the operational time of SIDs. Therefore, extending battery life problem has become of crucial research importance, at hardware and software levels, both alike. This paper firstly, makes contribution by reviewing different techniques at software level used to enhance battery life of SIDs in particular Smartphones. At the end, suggestions and opinions related to energy efficiency of SIDs are given, based on the comparative studies. Technical Session A2 Time : 1400 – 1520 Venue : Room 2 Session Chair : Dr. Bakhtiar Affendi Rosdi ID (#) S001 (1570025971) Title, Authors & Abstract Feature Extraction Using Spectral Centroid and Mel Frequency Cepstral Coefficient for Quranic Accent Automatic Identification Noraziahtulhidayu Kamarudin; S.A.R Al-Haddad; Abd Rauf Bin Hassan; Shaiful Jahari Hashim; Mohammad Ali Nematollahi This paper presents the process of Quranic Accent Automatic Identification. Recent feature extraction technique that is used for Quranic verse rule identification/Tajweed include Mel Frequency Cepstral Coefficients (MFCC) which prone to additive noise and may reduce the classification result. Therefore, to improve the performance of MFCC with addition of Spectral Centroid features and is proposed for used in feature extraction of Quranic accents. Through implementing the Spectral Centroid Feature, it complements in improving the accuracy result of identifying the Quranic accents. The pattern classification algorithm here used the dimensional reduced technique from Probabilistic Principal Component Analysis (PPCA) on the features and Gaussian Mixture Model, in purpose to model the effectiveness of both combination of feature extraction. The accuracy of automatic identification for such Quranic Accents are found increasing from 96.9% to 100% with the application of SCF. S002 (1570027031) Recognition & Counting Algorithm for Sub-Regional Objects in A Handwritten Image Through Image Sets Sriraman Kothuri; Komal Teja Mattupalli In this paper a novel algorithm is proposed for the recognition of hulls in a hand written images that might be irregular or digit or character shape. Identification of objects and internal objects is quite difficult to extract, when the structure of the image is having bulk of clusters. The estimation results are easily obtained while going through identifying the sub-regional objects by using the SASK algorithm. Focusing mainly to recognize the number of internal objects exist in a given image, so as it is shadow-free and error- free. The hard clustering and density clustering process of obtained image rough set is used to recognize the differentiated internal objects, if any. In order to find out the internal hull regions it involves three steps Preprocessing, Layered Outline Extraction and finally, apply the Hull Detection system. By detecting the sub-regional hulls it can increase the machine learning capability in detection of characters and it can also be extend in order to get the hull recognition even in irregular shape objects like wise black holes in the space exploration with their intensities. Layered hulls are those having the structured layers inside while it is useful in the Military Services and Traffic to identify the number of vehicles or persons. This proposed SASK algorithm is helpful in making of that kind of identifying the regions and can useful in undergo for the decision process (to clear the traffic, to identify the number of persons in the opponent's during the war). S003 (1570027093) Protective Covering of Images by Using Both Cryptography and Steganography Lavanya Kumari Kommu; Sriraman Kothuri In this paper, we proposed a new method of protective covering of images by using combinations of both cryptography and steganography [1] with segmentation of secret image. Cryptography is the process of scrambles the existing information where as in steganography, the information is embedded in the some other information. Firstly the secret image is divided into several parts and encrypts those parts separately with different encryption algorithms. After that combined all parts as a single image and embed that combined image in to the cover image. Finally that stego image is compressed to the size of the cover image and transmits it. S004 (1570031045) A Review on Pedestrian Detection Techniques Based on Histogram of Oriented Gradient Feature Chi Qin Lai; Soo Siang Teoh Locally normalized Histogram of Oriented Gradient (HOG) algorithm originally proposed by Dalal & Triggs presents excellent results for pedestrian detection. However, as the demand of accuracy and speed in real-time application increase, the detection speed and robustness of this method is becoming insufficient. . Over the years, improvements have been proposed by different researchers in order to meet the requirement of the robustness and processing speed. This includes the improvement in the ways HOG feature is extracted, combination of HOG feature with other image features and using part based detection method. This paper reviews the current advancement in HOG features for human detection. Technical Session A3 Time : 1400 – 1520 Venue : Room 3 Session Chair : Dr. Asrulnizam Abd. Manaf ID (#) R001 (1570024887) Title, Authors & Abstract Rain Attenuation At 40 GHz for Terrestrial Link in Malaysia Azlinda Tee Md Azlan Tee; J.S. Mandeep; Amran Naemat; Khaidir Khalil; Azah Syafiah Mohd Marzuki; Surati Selamat This paper presents the study on the rain attenuation at 40 GHz via terrestrial link in Malaysia. Malaysia is situated in the tropical region and known to experience a very heavy rainfall annually. Consequently this heavy rainfall has high impact on the propagating signals. In this study, rainfall data from Cyberjaya were collected using rain gauge, and then they were analyzed to get the rainfall rate in term of probability of the time exceedance. Five different prediction models were used to estimate the rain attenuation values; ITU-R 53015 models, ITU-R 530-13 models, revised Moupfouma's model, revised Silva Mello's model and Lin's model. Among these five models, ITU-R 530-15 model R002 gave the closest estimated value to the measured rain attenuation at 38 GHz. By applying this model with the acquired rainfall rate of 130 mm/h, it gave the estimated attenuation value of 22.64 dB within 0.3 km propagating path at frequency of 40 GHz. Corporate Series Feed Circular Spiral Antenna Array for UHF Applications Kang Chia Chao; Mohd. Fadzil bin Ain (1570029021) R003 (1570031253) Circular Spiral with twelve element corporate-series feed antenna array operates at the center frequency of 956MHz is designed and analyzed. Each of the single circular spiral inductor is connected after one another. The purpose of design the circular spiral corporate-series feed antenna array is to achieve high gain antenna and subsequently harvesting more RF energy. The quarter wave transformer method is used to design the corporate feed line with the same equal distributed power in each arm. The entire structure was investigated using numerical solver such as finite integration technique (FIT) method. With this setup, the results show that 19.8dB gain for antenna array can be achieved at frequency 956MHz. Therefore, the results obtained are a very attractive new method design solution for application in the UHF band in future. A good agreement between simulation and measurement results is successfully confirmed. 60-min to 1-min Rainfall Rate Conversion Using East Malaysia Data Surati Selamat; Azah Syafiah Mohd Marzuki; Azlinda Tee Md Azlan Tee; Khaidir Khalil; Amran Naemat Wireless communication systems operating at above 10 GHz are exposed to rain attenuation. Therefore, countries with high precipitation rate such as Malaysia, require careful planning before establishing a reliable wireless link. Signal attenuation due to rain can be measured or estimated, but it requires the knowledge of local 1-minute rainfall rate statistic. But for most part of the world, the rainfall data usually comes with higher integration time, such as 60-minute. As a result, the method to convert rainfall rate with higher integration time to 1minute rainfall rate distribution is essential. In this study, hydrological data from five areas in East Malaysia is translated to 1-min and 60-min rainfall rate distribution. Then, five conversion models were used to convert 60-min rainfall rate to 1- min rainfall rate. From observation and conversion error analysis, this study found that Segal method performed the best when it is compared to other four conversion methods. R004 (1570031315) Electronically Steerable Antenna for WLAN Application N. A. Salleh; E. Mohd; N. Abdullah In wireless communication systems, interference becomes a major problem in limiting the quality of the transmitted and received signals. A common problem in wireless communications is to eliminate the interference signal that is mixed with the original signal. Thus, adaptive beamforming is proposed to eliminate the interference signal. This paper presents an adaptive antenna using a slotted patch antenna for WLANs operated at 2.4 GHz. A reactively steerable antenna concept has been applied. A downhill simplex algorithm is used to maximize the cost function. The radiation pattern of the antenna is controlled by the reactance value connected to each port. From numerical simulation, null is performed for the incoming interference. Technical Session A4 Time : 1400 – 1520 Venue : Room 4 Session Chair : Dr. Zuraini Dahari ID (#) C001 (1570024851) Title, Authors & Abstract Optimizing Visual Sensor Parameters for Total Coverage Maximization Altahir A. Altahir; Vijanth S. Asirvadam; Nor Hisham B Hamid; Patrick Sebastian Modeling the sensor coverage is evidently indispensable to meet the requirements of a variety of visual sensor related applications. It is critical to be able to compute the camera coverage and to plan the system accordingly. However, optimizing the visual sensor parameters directly impacts the total performance in visual surveillance applications. This work highlights the theoretical bases of camera modeling. Moreover, the work focuses on calculating the visual sensor coverage via implementing a different set of parameter to maximize the total coverage. A complex scenario is used in the simulation and the results are presented in a comparative manner. The proposed method is capable of computing the camera coverage area in highly occluded scenes. C002 (1570025363) Feature Extraction for Co-Occurrence-Based Cosine Similarity Score of Text Documents Ammar Ismael Kadhim; Lubab Salman; Yu-N Cheah; Nurul Hashimah Ahamed A major challenge in topic classification (TC) is the high dimensionality of the feature space. Therefore, feature extraction (FE) plays a vital role in topic classification in particular and text mining in general. FE based on cosine similarity score is commonly used to reduce the dimensionality of datasets with tens or hundreds of thousands of features, which can be impossible to process further. In this study, TF-IDF term weighting is used to extract features. Selecting relevant features and determining how to encode them for a learning machine method have a vast impact on the learning machine methods ability to extract a good model. Two different weighting methods (TF-IDF and TF-IDF Global) were used and tested on the Reuters-21578 text categorization test collection. The obtained results emerged a good candidate for enhancing the performance of English topics FE. Simulation results the Reuters-21578 text categorization show the superiority of the proposed algorithm. C003 (1570025691) Computational Intelligence Approach in Optimization of a Nanotechnology Process M. S. Norlina; P. Mazidah; N. D. Md. Sin; M. Rusop Computational intelligence has been widely adapted in various fields and has been demonstrated excellent performances in solving optimization problems. This study is proposing the implementation of gravitational search algorithm (GSA) in the parameter optimization of RF magnetron sputtering process. RF magnetron sputtering is a nanotechnology process which involves the deposition of nano-scaled atoms of a target material. The current practice of searching for the optimized parameters in the magnetron sputtering process is based on the trial and error method. However, this conventional method has been reported to be time consuming and costly. GSA is proposed to identify the most optimized parameter combination for producing the desirable zinc oxide (ZnO) thin film electrical property. GSA is a population based algorithm which is based on the Newton's law of gravity and the law of motion. This study is concentrating on three magnetron sputtering process parameters, which are RF power, argon and oxygen flow rates. These three process parameters are among the sputtering process parameters that have been extensively studied by the researchers for the fabrication of the nanostructured ZnO thin film. The result from GSA optimization had showed that the algorithm was able to identify the most optimized parameter combination from the set of parameters. Based on the GSA acceptable performance, it is expected that this technique could serve as an improvement from the traditional practice in the fabrication process. C004 (1570027853) Partially Adaptive Look-Ahead Routing for Low Latency Network-on-Chip Nadera Najib; Alireza Monemi; Muhammad Nadzir Marsono Adaptive routing algorithms offer the ability to avoid congestion by supporting multiple paths between a source and destination. However, supporting adaptive routing for low latency routers is a challenge due to the computation of routing algorithm in one router in advanced (i.e) look-ahead routing). This paper presents an RTL architecture for adding partially adaptive look-ahead routing algorithm to a recently proposed low latency, virtual channel wormhole Network-on-Chip (NoC) router. In our proposed design each router precomputes the preferred output ports based on its local congestion and transfers the preferred output ports to the neighboring routers. These preferred output ports are used in the look-ahead routing to select the optimal output port for the packet. We compare our proposed partially adaptive routing architecture with the reference design using look-ahead XY routing algorithm under matrixtranspose traffic and obtained 10% improvement at maximum injection ratio. Our proposed routing algorithm has negligible influence in area overhead (<2%) while has no influence on maximum operating frequency. Technical Session B1 Time : 1540 – 1700 Venue : Room 1 Session Chair : Dr. Nor Muzlifah Mahyuddin ID (#) N005 (1570024703) Title, Authors & Abstract On the Distribution of the Length of Bit Errors in IP Packet Headers Liawas Barukang; Garik Markarian This paper concerns itself with the distribution of the length of bit errors in IP packet header. MAC frames (encapsulated the IP packets) are transmitted through an AWGN channel and modulated with BPSK. At the receiver, the numbers of bit errors in the header in every IP packets are recorded. The probability of each length of bit errors is computed and length of error histogram plotted. The result shows that in an un-coded channel, the average length of error having the highest probability to occur is about 21-bits, whereas for coded channel, it was about 60-bits. However, the probability of having 21bits length bit errors in un-coded channel is significantly higher than the probability of having the 60-bits length bit errors in coded channel. Furthermore, bit errors are found in packet header of packets transmitted through an uncoded channel when SNR is between -2dB to +10dB, whereas in coded channel, there is no more bit errors found in the packet header when SNR is from +6dB onward. This result is beneficial in deciding on an optimal numbers of redundancy bits needed to protect the IP packet header. N006 (1570024813) Effects of Hand on EM Absorption of Internal Handset Antenna M. I. Hossain; M. R. I. Faruque; M. T. Islam; T. Alam An analysis of hand impact on internal handset antenna electromagnetic (EM) absorption is presented in this paper. An E-shaped planar inverted-F antenna (PIFA) is designed for handset antenna. The handset is placed in talk mode in the closed vicinity of human head and hand phantom. The specific absorption rate (SAR) in the human head and total absorbed power by the user are utilized to evaluate EM absorption. The analysis was performed in both cheek and tilt positions of talk mode. The main part of the investigation is based on the finitedifference time-domain (FDTD) method of CST microwave studio. The results indicate that the SAR values are decreased and total absorbed power by user increased significantly due to inclusion of user's hand. N007 (1570026069) Printed Microstrip- Fed Circular Patch Antenna for Wireless Communication M. I. Hossain; M. R. I. Faruque; M. T. Islam; T. Alam In this paper, a new wideband Circular monopole antenna is proposed for Wireless communication. Commercially available software Computer Simulation Technology (CST) microwave studio based on finite difference time domain (FDTD) was adopted in this investigation. A wide frequency bandwidth of 3.25 GHz (1.65 GHz to 4.9 GHz.) has obtained in measurement. The operating frequencies of the proposed antenna are GSM-1800, GSM-1900, UMTS, Bluetooth (2400-2800) MHz, WLAN (2400-2485) MHz, WiMAX (2500-2690) MHz and WiMAX (3400-3600) MHz. The antenna has been printed on FR-4 (lossy) Substrate with relative Permittivity of 4.6 and thickness of 1.6 mm. The computational results has been validated the measured one. In addition, the electromagnetic absorption analysis has been investigated for the proposed antenna. N008 (1570022439) A Review of Simulation Framework for Wireless Sensor Networks Localization Noorfarha Mohd Ngabas; Jiwa Abdullah Wireless sensor networks have the capability to deliver the environmental data to the user. Among the significant data is the location of the node either in static or mobile. A number of network simulators were extensively reviewed specifically for the development of wireless sensor networks protocol. However, there is little work done in assessing the framework for localization simulation. This paper addresses the lack of the previous surveys by giving the guidelines for localization developer to select the suitable network simulator or programming language. It includes a comparative description on importance features in evaluating the localization algorithm. In addition, it discusses the general performance evaluation metric use for localization. Finally, it list several open issues which help in developing and analyzing the localization algorithm. Technical Session B2 Time : 1540 – 1720 Venue : Room 2 Session Chair : Dr. Norliza Mohd. Noor ID (#) S005 (1570031723) Title, Authors & Abstract Cardioid Graph Based ECG Biometric Recognition Incorporating Physiological Variability Fatema-tuz-Zohra Iqbal; Khairul Azami Sidek This paper investigates ECG signal in different physiological conditions to identify different individuals. Data was acquired from 30 subjects, where each subject performed six types of physical activities namely walking, going upstairs, going downstairs, natural gait, lying with position changed and resting while watching TV. Then from the signals of these physiological conditions, specific features exclusive to each subject was extracted employing the Cardioid graph method. In this model, features were extracted solely from the graph derived using QRS complexes. Subjects were recognized with Multilayer Perceptron. Results were obtained through two approaches. In the former procedure, classification was performed on the whole dataset consisting of both training and testing set, which produced 95.3% of correctly classified instances. In the later approach the training and testing set was predefined where correctly classified instances were 93.9%. These results confirm that subject identification at different physiological conditions with Cardioid graph based technique produces better classification rates than previous study using only QRS complex. S006 (1570037299) A Selective Algorithm for the Reduction of Irregular Noise in Speech Communication Roshahliza M. Ramli; Ali O. Abid Noor; Salina Abdul Samad The properties of noise signals can be the main problem associated with noise cancellation systems. In order to overcome this problem, high complexity algorithms have to be used in order to reduce the noise embedded in the useful signals such as speech. This method can be impractical, especially in real-time applications where the computational power is a crucial issue. Adaptive filters give applicable solutions, but most literature proposed a single, yet complex algorithm to removing the noise. This paper proposes an alternative approach to eliminate background noise in corrupted speech signals. The method is achieved by letting the system assigns an appropriate algorithm according to the characteristics of the noise. The criterion used here is based on the calculation of eigenvalue spread in the autocorrelation matrix of the input signal. In addition, an algorithm derived from set-membership filtering is also used among the selected algorithms. This approach showed its potential capability in eliminating different types of environmental noise from corrupted speech signals. The technique presented here exhibited fast convergence speed and improvement in signal-to-noise ratio compared with other single adaptive algorithms. S007 (1570017773) Detecting Brain Tumor in Magnetic Resonance Images Using Hidden Markov Random Fields and Threshold Techniques Hayder Saad Abdulbaqi; Iskandar Shahrim Bin Mustafa Loay Kadom Abood; Mohd Zubir Mat Jafri; Ahmad Fairuz Omar Brain tumors are created by abnormal and uncontrolled cell division in the brain itself. Manual segmentation of brain tumors from MRI is a crucial and time consuming task. Accurate detection of size and location of brain tumor plays a vital role in the successful diagnosis and treatment of tumors. So the detection of brain tumor needs to be fast and accurate. Brain tumor detection is one of the challenging tasks in medical image processing. This paper concerns presenting an approach which will be useful for improved detection of brain tumor using Hidden Markov Random Fields (HMRF) and Threshold method. The proposed method has been developed in this research in order to construct hybrid method. The aim of this paper is to introduce a scheme for tumor detection in Magnetic Resonance Imaging (MRI) images using (HMRF) and Threshold techniques. These methods have been applied on 3 different patient data sets. They are capable to regularize their soothing effect on the final segment of brain tumor homogeneous tissue regions, whilst edges between different tissue components are better preserved. S008 (1570025667) Identification of Phoneme and Its Distribution of Malay Language Derived From Friday Sermon Transcripts Mohd Ibrahim Shapiai; Mokhtar Harun; Muhammad ‘Aasim Asyafi’ie; Puspa Inayat Khalid Lack of text data is one of the main issues encountered by researchers on Malay speech. This text data is in the form of text corpora that is essential to provide empirical data for researchers in the field of linguistics, and are useful to construct word lists for speech intelligibility test, speech analysis across genders and automatic speech recognition. The text corpora also need to mimic the natural phoneme of the language it represents. To accomplish this, we need to know the phonetic distribution of the language. So far, there are no published results on the phonetic distribution of a kind Malay language. The purpose of this research is to identify phoneme distribution for the Malay language based on the transcripts obtained from fifty two Friday sermons. The Friday sermon transcripts were obtained through the official government website and then standardized by removing images and foreign letters; expanding acronyms and short forms; converting numbers and symbols to appropriate Malay words. The transcripts were then phonetically transcribed by first identifying the language rules and wrote a program based on those rules. The program was written using Personal Home Page (PHP) and the data were then stored into MySQL (Sequential Query Language). The data were then retrieved and compared to the Malay words used in news broadcast. In conclusion, the Malay used in Friday sermon and news broadcast differs in the usage of the phonemes /a/, /e/, /o/, /d/, /p/, /tʃ/, /n/, /l/, /h/ and /r/. S009 (1570035809) Electrocardiographic (ECG) and Electromyographic (EMG) Signals Fusion for Physiological Device in Rehab Applicaton Nor Aziyatul Izni Mohd Rosli; Mohd Azizi Abdul Rahman; Saiful Amri Mazlan; Hairi Zamzuri In this paper, a preliminary work on improving fitness in the post-stroke rehab application is investigated. For this purpose, a fusion of the Electrocardiographic (ECG) and Electromyographic (EMG) biosignals is proposed to produce a significant control signal and to achieve a biosignals multimodal fusion system. In this work, the mathematical approach such as the Bayesian network will be applied for combining the ECG and EMG biosignals. Furthermore, the significant fused elements can be applied to control to manipulate the control of physiological device (PDs) for emulating classic rehabilitation exercise (e.g., cycling). Consequently, the proposed method for a multimodal fusion of muscle contraction for heart and lower limbs shall give improvement on monitoring the rehabilitation progress with better accuracy for signals fusion. Technical Session B3 Time : 1540 – 1720 Venue : Room 3 Session Chair : Dr. Badrul Hisham Ahmad ID (#) Title, Authors & Abstract R005 Reconfigurable Multiband Bandpass Filters Using Short Bridges Resembling MEMS or Pin Diodes (1570031345) Zeshan Ali; Zuhair M. Hejaz A simple technique is used to design a new compact reconfigurable multiband bandpass filter (BPF). The propose technique is very feasible for reconfigurable operation. The concept is experimentally validated by placing solder bridges across filter structure at the appropriate positions. The proposed structure has very minor effect on the performance of the original multiband filter, due to minor losses of the short bridges. The responses achieved, range from a single UWB BPF to triple-band BPF. Excellent agreement of measured results with the simulations is observed. M001 (1570020317) N-job, M-Macine Lot Streaming Problem with Learning Effects Navid Mortezaei; Norzima Binti Zulkifli The abilities of workers for performing same or similar tasks can be improved by repeating them. This phenomenon is recognized as learning effects. Many researches performed on the effects of learning in scheduling problems. However, there is not any study about lot streaming problem with learning considerations. In this study, we develop mixed-integer mathematical models for multiple products and multiple machines lot streaming problem with learning considerations.

The current biosensor market needs easy manufacturing in large quantities, low cost, small in size, easy to be used and fast response time, thus, an appropriate optical waveguide material needed to be chosen. Hence, the optical properties of SU-8 must be well understood in order to design waveguide with single-mode and strong evanescent field to realize sensitive biosensor. It is known that process parameters such as spin speed, exposure dosage and curing temperature affect the polymerization which in turn affect the optical properties especially refractive index. Due to this reason, it is the aim of this paper to investigate the effects of spin speed, exposure dosage and curing temperature on the refractive index of SU-8. This paper also aims to improve the process recipe of SU-8 for waveguide fabrication which requires high resolution and steep sidewall with minimum defect.

Inwheel direct drive eliminates the mechanical transmission, differential gears and drive belts. Thus, in-wheel direct drive provides quick torque response, higher efficiency, weight reduction, and increased vehicle space. As one of alternative, a new design of hybrid excitation flux switching motor (ORHEFSM) for in-wheel drive EV is proposed. In this paper, the optimization design of single-phase 8S-4P outer rotor HEFSM is analysed. Open and close circuit of initial and final design is comparedbased on 2-D finite element analysis (FEA). The optimized design motor has produced higher torque which is 138.18Nm with 22.2% improvement compared to initial design motor which is 107.5Nm and has achieved the target value which 111Nm. The initial maximum power achieved was 17.02kW, while for the improved design motor, it has increased to 41.81kW, since the target maximum power is 41kW. The design optimization has been made on the initial design machine shows that there is great enhancement on torque and power P002 (1570008973) Performances Comparison of 12S-14P Field Excitation Flux Switching Motor with Overlap and Non-overlap Windings for Hybrid Electric Vehicles Zhafir Aizat Husin; Erwan Sulaiman; Faisal Khan; Mohd Fairoz Omar Hybrid electric vehicles (HEVs), using combination of an internal combustion engine (ICE) and one or more electric motors, are widely considered as the most promising clean vehicles. The only machine that already installed for HEVs is interior permanent magnet synchronous machine (IPMSM) where it has developed to enhance power density of the machine. Despite of fine operated and superior performances, this machine do not miss approached by deficiency for instance IPMSM now have complex form and configuration that give difficulty to undertake the process of optimization. Moreover, the use of PM will result in a constant state of flux and cannot be controlled as well a burden because of expensive rare earth magnet prices. Therefore, a new candidate of field excitation flux switching machine (FEFSM), in which the uses of PM are totally excluded with rugged rotor structure suitable for high-speed operation and the ability to keep high torque and power density is proposed and examined in this paper. Under some design specifications, design principles and performances of 12S-14P FEFSMs with overlap and non-overlap FEC and armature coil windings are presented. The profile of flux linkage, induced voltage, cogging torque, torque and power characteristics are observed based on 2D finite element analysis (FEA).

This paper presents an experimental evaluation of applying wavelet packet transform based on the sideband components, (1 ± 2ks)fs , for broken rotor fault detection in induction machines. The wavelet-based method decomposes stator current signal into effective wavelet coefficients. It is shown that the root mean square (RMS) value of wavelet packet coefficients in special frequency bands collectively establishes a feature index. Once the broken rotor bar occurs, this index value increases to distinguish healthy and faulty mode of induction motor as well as fault severity. Additionally, we investigate the left sideband around the fundamental frequency (50Hz), (1 – 2s)fs, which specifically represents the stator current spectrum of the machine when a rotor bar breakage takes place. An induction motor with one and two bar breakage at 35%, 50% and 80% of full load are investigated. The experimental tests indicate good reliability of different frequency resolution for same frequency component.

In order to achieve a better drive range and improved performance of the motor, control techniques are necessary for the DC to DC power converters which are employed in these vehicles. Designing of linear controllers for these converters like Proportional Integral (PI) is pretty straightforward which requires mathematical modeling of the system , Whereas the designing of non-linear controllers like Fuzzy Logic Controller (FLC) is completely trial and error and does not require the mathematical modeling of the system.

H. Wahid; M. Rusop; Z. Nurbaya Development of innovative device design was fully utilized to fabricate hybrid composited PVDF-TrFE/PbTiO3 that having bilayered films capacitors. Step by step of layer deposition trough spin coating method had performed an optimal thickness of ~319 nm PbTiO3 first layer and ~470 nm polymer second layer. It was found that averagely 55.6 nm multigrain size of PbTiO3 performed high densification films with minimal porosity behaviour. Thus, the co-polymer layer plays important role to cover up the porosity and as well as the stiffness of the PbTiO3 first layer with membrane like structured films. The dielectric measurement of the bilayered films showed the reduction of dielectric constant at low frequency compared to the PbTiO3 single layer, however, contrary effect on tangent loss (tan (δ)) measurement. The equivalent capacitance value of both films configuration showed some interest where the significant consideration of series capacitance effect on bilayered films could be ignored. Therefore, to the best of our known, the significant of this study is to investigate dielectric and structural property of nanoscaled device using hybrid combination of polymer/ceramic having bilayered composition based metal-insulator-metal capacitors.

In this study, the electronic and transport characteristics of armchair graphene nanoribbon (AGNR) with a Stone-Wales (SW) defect is investigated. The SW defects are located at three different locations on the AGNR device; underneath the metal gate, near the drain edge and near the source. The band structures, density of states and transmission spectra are analyzed. The current-voltage characteristics are then extracted and the performance of pristine AGNR and AGNR incorporated with the SW defects is analyzed. From the simulation, it is found that the position of the SW defect on the AGNR device alters the electronic and transport properties of the AGNR. Remarkably, the SW defect increases the amount of energy bandgap, while decreasing the drain current. The outcome of this study suggests that defects present on AGNR are not unreasonable and may be useful to enhance transport properties.

Later, report sheets were generated based on these analyses. The results showed that the PPG signal as well as HRV changes depending upon the physiological conditions.It was also examined that the low and high frequency components of PPG signal also varied according to the change in physiological condition. E013 (1570030755) Transabdominal Fetal Pulse Oximeter Using LEDs and Photodiode: A Design Consideration Study Nur Anida Jumadi; Gan Kok Beng; Mohd Alauddin Mohd Ali; Edmond Zahedi This paper presents a design consideration study of portable light detection components to be applied in the transabdominal fetal pulse oximeter. Several limitations are found in the previous fetal oximeter sensors. The sensors are either suitable to be used for invasive technique, high-power dependent or bulky in size. The selection of the light source is considered based on several parameters such as wavelength, angle of half intensity, power dissipation and cost. Meanwhile the selection of light detector is depends on the active area, electrical-optical characteristics, photodetector noise and cost. An instrumentation system setup utilizes the chosen sensors has been developed. In order to evaluate the capability of the proposed sensors, two measurements are done based on the sensors modes arrangement; transmission and reflectance. The preliminary results show that the developed system is able to measure the PPG signals in two different modes. From the experiment observation, the current limit resistor and the emitter-detector spacing are the two pertinent parameters that affect the operation modes of the proposed sensors.
