Faculty of Engineering (FOE), Cyberjaya Campus QoS Provisioning of 5G Heterogeneous Network

The current cellular technology and vehicular networks cannot satisfy the mighty strides of vehicular network demands. Resource management has become a complex and challenging objective to gain expected outcomes in a vehicular environment. The 5G cellular network promises to provide ultra-high-speed, reduced delay, and reliable communications. The development of new technologies such as network function virtualization (NFV) and software defined networking (SDN) are critical enabling technologies leveraging 5G. The SDN provides flexibility in communication administration and resource management, which are of critical importance when considering the ad-hoc nature of vehicular network infrastructures, in terms of safety, privacy, and security, in vehicular network environments. However, the frequent handover activities in the vehicular network remain a challenge to provide the Quality of Service (QoS) to the users. Artificial Intelligence enabled architecture can be used to cater to the sophisticated demands of modern vehicular Internet infrastructures. The inclination towards robust communications in 5G-enabled networks has made it somewhat tricky to manage network slicing efficiently.

Faculty of Engineering and Technology (FET), Melaka Campus Human Identification Using ECG Signals

Analysis of electrocardiogram (ECG) signal has been an active research area in the past two decades. Most of the past works was motivated by applications in clinical diagnoses. Recently, another potential application of ECG analysis has drawn more attention in the research community. Human individuals presents different patterns in their ECG regarding wave shape, amplitude, PT interval etc. due to the difference in the physical conditions of the heart. This characteristic of ECG signal raises the potential of applying ECG for biometric identity recognition. One important issue in the design of a biometric system is the robustness against attacks. However, many of the existing biometrics are easy to be spoofed. EGG based biometric system is expected to be more universal and hard to mimic.

In this project, we will propose a new approach for identification of human subjects from ECG signals.

Faculty of Engineering and Technology (FET), Melaka Campus Analysis of 1D Biomedical Signals through AI-based Approaches for Image Processing

The automatic analysis of biomedical signals has become an important process to both identify indicators of diseased states and to provide meaningful information for various applications in physiology, sports medicine and human–computer interface.

Recent advances in Artificial Intelligence (AI) have the potential to manage and analyze large biomedical datasets leading to the clinical decisions and real-time applications. These techniques have been applied successfully to medical imaging, but the analysis of 1D biomedical signals has yet to fully benefit from this novel approach. ECG, EMG, PCG, PPG, BCG, skin temperature, and skin conductance are some of the 1D biomedical signals examples that record the dynamic changes of the human body.

Faculty of Engineering and Technology (FET), Melaka Campus Early Drowsiness Detection of Drivers using Artificial Neural Network Focusing on Behavioral, Driving, and Physiological Features

One of the leading causes of traffic accidents is the drowsiness of the drivers. Around 20% (Guede-Fernández et al. 2019) of car crashes are occurred due to drowsiness. Accurate early identification of drowsy driving is required to minimize such accidents.

Previous studies mostly focused on facial features and applied conventional machine learning algorithms like SVM, KNN, etc., to detect the driver’s drowsiness. These studies also missed the driver’s slight drowsiness stage and failed to detect the early drowsiness. However, only facial features are not sufficient to detect drowsiness. Drowsiness depends on multiple features like driving performance, behavioral features, and physiological response. Although, previous researches did not utilize these features simultaneously.

Therefore, the study aims to propose a noble artificial intelligence system to predict the driver’s early drowsiness. The system will emphasize all the major features related to the drowsiness of the driver. It will also consider the slight drowsiness stage of the driver to make the model more efficient.

All the fractures will be categorized into behavioral, driving, and physiological features. The behavioral feature includes eye blink, yawning, duration of eye-opening. Vehicle velocity, vehicle acceleration, steering wheel acceleration, and distance from lane center will be considered driving performance. And, the features obtained from the EEG and ECG signal will be contemplated as a physiological response. All the extracted features will be arranged according to the drowsiness level after the pre-processing stages. A noble Artificial Neural Network (ANN) will be implemented to classify and predict the early drowsiness of the driver.

As the proposed system would have the ability to detect drowsiness at the early stage considering all the possible features, it would play a significant role in the driver drowsiness detection system. Moreover, the system would reduce the probability of sudden death of a human being due to drowsiness.

Faculty of Engineering  (FOE), Cyberjaya Campus A Novel Architecture of Maximum Power Point Tracking Algorithm for Ultra-Low-Power based Hybrid Energy Harvester in Ubiquitous Devices

This research work presents a novel architecture of an Ultra-Low-Power (ULP) based Hybrid Energy Harvester (HEH) consisting of multiple input sources such as kinetic, thermal and solar energy, harvested from passive human power. Having multiple ambient sources mitigates limitations caused by single sources especially for bodily-worn applications; however, this results in impedance mismatch among the different integrated sources. To overcome this limitation, the proposed ULP based HEH will use one power management unit with Maximum Power Point Tracking (MPPT) algorithm and impedance matching considerations to efficiently manage and combine the power harvested from all three sources to achieve ULP consumptions. Among other crucial sub-modules of the proposed HEH are its Asynchronous Finite State Machine (AFSM) cum resource sharing arbiter to prioritize and share energy sources for overall power reduction, an efficient rectification scheme for the piezoelectric input, an adaptive feedback for low power conditioning, Zero-Current Switching (ZCS) for semi-lossless switching in its on-chip energy storage, a self-start circuit for low ambient startup of 20 mV, a Boost converter to pump-up voltage levels, a Buck regulator to stabilize fluctuating voltage levels, a fuzzy-based micro-battery charger and a multiplexer to switch between harvesting or charging capabilities. All of which is implemented for maximum output extraction and minimal losses. The approach of developing this ULP-HEH begins with a literature review on past HEH architectures. Next, all ULP-HEH sub-modules will be modeled, designed and simulated in PSPICE software with MPPT algorithm; and charging technique in MATLAB. After achieving optimum results, the developed HEH system will then be written in Verilog coding under Mentor Graphics environment and later the designed codes are to be downloaded on the Field Programmable Gate Array (FPGA) board for verification purposes. Once verified, the ULP-HEH will finally be implemented into the layout level using the CMOS 0.13 µm process technology. This ULP based HEH system is expected to operate at 4kHz and deliver up to 3.0-5.0V of regulated voltage output from ambient sources with a minimum input voltage of 35 mV to startup without batteries to aid its proposed (end-to-end) peak efficiency of 90% or above with an output power of about 650 µW when all sources are summed. Also, the proposed HEH is aimed at reducing power consumption to at least 2 times (<70 µW) of the conventional HEH due to multi-sourcing impedance mismatch. The proposed ULP based HEH system can be widely used for low power bodily-worn electrical gadgets, wearable biomedical devices or to power or charge micro-batteries for portable electronic devices.

Faculty of Engineering  (FOE), Cyberjaya Campus Focal Point Calibration of Antenna to Minimize Background Noise of Reflected Scattering Objects.

The focal point calibration of antenna is a prime parameter to reduce the background noise of reflected scattering objects for tumor detection in microwave imaging technique. Very small size tumors or any unwanted cell can be detected with high accuracy bycalibrating the focal point of the antenna with minimizing the background noise. However, due to low spectral power density and weak scattering behavior of the body tissue, reflected scattering objects must rely on the very low power reflections, which are often drowned out by the background noise and reflections from the nearby scattering objects. Thus, it is essential to overcome the drawbacks in terms of susceptibility to background noise and scattering objects, false detections, low-resolution scanning, and uncomfortable processing. It is necessary to determine the antenna phase center for accurate ranging, signal processing, and image reconstruction since it makes the antenna simple as a point source. The main aim of this project is to introduce and explore a new approach of antenna focal point calibration by utilizing a new optimization technique. The new parallel-start variant of iterative optimization (PSVI) approach will be assessed to heuristically optimize the focal point of the antenna with respect to the imaging domain. The difference between the two data sets will be calculated and measured due to the generated noise from reflected scattering objects. After that, the antennas will be used to reduce the background noise of reflected scattering objects that will detect the tumor or any unwanted cell inside the body phantom. The noise and artifact reduction of the images using the optimized antenna will be evaluated by comparing with the antenna without the optimal focal point. The expected outcome of this project has the potential to generate noiseless images that significantly paves the detection of tumor or any unwanted cell.
