Observation of the Effects of Playing Games with the Human Brain Waves

The purpose of this paper is to observe the human brain waves when a person playing video games. The game proposed is Counter Strike (CS) 1.6. There are 30 samples of human brain wave will be collected. The EEG signal will be recorded before playing a game and after playing a game. The threshold value is used to filter the data collected to acquire clean brain waves. Then, extraction of sub-band Alpha and Beta is done by Band-pass filter. Power Spectral Density (PSD) is performed in analysing the brain waves to acquire peak amplitude of the Alpha and Beta sub-band frequencies. The pattern of Alpha and Beta is carried out by using the histogram to observe the relationship between games and mind state of humanity. It is observed that the Beta-band increase and Alpha-band decrease after the samples playing game

Elbow Flexion and Extension Rehabilitation Exercise System Using Marker-less Kinect-based Method

This paper presents the elbow flexion and extension rehabilitation exercise system using marker-less Kinect-based method. The proposed exercise system is developed for the upper limb rehabilitation application that utilizes a low cost depth sensor. In this study, the Kinect skeleton tracking method is used to detect and track the joints of upper limb and then measure the angle of the elbow joint. The users perform the exercise in front of the Kinect sensor and the computer monitor. At the same time, they can see the results that displayed on the screen in real-time. The measurement of elbow joint angles are recorded automatically and has been compared to the reference values for the analysis and validation. These reference values are obtained from the normal range of motion (ROM) of the elbow. The results show the average flexion angle of the elbow joint that achieved by the normal user is 139.1° for the right hand and 139.2° for the left hand. Meanwhile, the average extension angle is 1.72° for the right hand and 2.0° for the left. These measurements are almost similar to the standard range of motion (ROM) reference values. The skeleton tracking works well and able to follow the movement of the upper arm and forearm in real-time

Brain Dominance Using Brainwave Signal

The study of brain dominance in human-computer interaction has increased in recent years in an attempt to address the need of users especially who cannot read or write. The objective of this paper is to determine the brain dominance from brainwave signal that are measured using Emotive device and to analyse the pattern of brain dominance brainwave signal by using signal processing. The result of Power Spectral Density (PSD) and Energy Spectral Density (ESD) from brainwave will be validated with Hermann Brain Dominance Instrumentation (HBDI) questionnaire. The result shows that most sample are left brain dominance. The result also shows that Beta and Delta indicate the left-brain dominance whereas Beta is indicates rightbrain dominance

K-NN Classification of Brain Dominance

The brain dominance is referred to right brain and left brain. The brain dominance can be observed with an Electroencephalogram (EEG) signal to identify different types of electrical pattern in the brain and will form the foundation of one’s personality. The objective of this project is to analyze brain dominance by using Wavelet analysis. The Wavelet analysis is done in 2-D Gabor Wavelet and the result of 2-D Gabor Wavelet is validated with an establish brain dominance questionnaire. Twenty-one samples from University Malaysia Pahang (UMP) student are required to answer the establish brain dominance questionnaire has been collected in this experiment. Then, brainwave signal will record using Emotiv device. The threshold value is used to remove the artifact and noise from data collected to acquire a smoother signal. Next, the Band-pass filter is applied to the signal to extract the sub-band frequency components from Delta, Theta, Alpha, and Beta. After that, it will extract the energy of the signal from image feature extraction process. Next the features were classified by using K-Nearest Neighbor (K-NN) in two ratios which 70:30 and 80:20 that are training set and testing set (training: testing). The ratio of 70:30 gave the highest percentage of 83% accuracy while a ratio of 80:20 gave 100% accuracy. The result shows that 2-D Gabor Wavelet was able to classify brain dominance with accuracy 83% to 100%

Leader Follower of Quadrotor Micro Aerial Vehicle

A Micro Aerial Vehicle (MAV) is known as a drone or in a bigger size is called Unmanned Aerial Vehicle (UAV). Quadrotors are leading edge of a huge development in military and civilian such as disaster search and rescue, surveillance, aerial mapping and others. However, those applications limits by the payload delivered and long execution time. Hence, this study focuses on Leader-Follower approach of Quadrotor MAV. The study covers the development of quadrotor platform, modelling, controller design and leader-follower implementation. As the preliminary study, an Android phone is used as a leader which is used to provide the desired position and orientation to the follower quadrotor. The follower will be an autonomous quadrotor. Proportional Integral Derivative (PID) controller for the position and attitude control are first designed and tested via simulation. Then, a real flight implementation is conducted. The result shows that the follower can follow the leader on a circular path and straight line path. The settling time for X, Y and Z position of the follower is 10.22, 10.90 and 19.45 seconds, respectively. Additionally, the overshoot percentage for X, Y and Z position are 7%, 0% and 0%, respectively

Random subspace K-NN based ensemble classifier for driver fatigue detection utilizing selected EEG channels

Nowadays, many studies have been conducted to assess driver fatigue, as it has become one of the leading causes of traffic crashes. However, with the use of advanced features and machine learning approaches, EEG signals may be processed in an effective way, allowing fatigue to be detected promptly and efficiently. An optimal channel selection approach and a competent classification algorithm might be viewed as a critical aspect of efficient fatigue detection by the driver. In the present framework, a new channel selection algorithm based on correlation coefficients and an ensemble classifier based on random subspace k-nearest neighbour (k-NN) has been presented to enhance the classification performance of EEG data for driver fatigue detection. Moreover, power spectral density (PSD) was used to extract the feature, confirming the presented method's robustness. Additionally, to make the fatigue detection system faster, we conducted the experiment in three different time windows, including 0.5s, 0.75s, and 1s. It was found that the proposed method attained classification accuracy of 99.99% in a 0.5 second time window to identify driver fatigue by means of EEG. The outstanding performance of the presented framework can be used effectively in EEG-based driver fatigue detection

PSO Based Optimal Reactive Power Dispatch (ORPD) Considering Multi-Contingencies

A stable power system can be subjected to voltage fluctuations due to poorly regulated reactive power flow that causes system instability. Reactive power is closely related to system voltage control, therefore, it is crucial to ensure the correct amount of reactive power is supplied to the system loads to achieve smooth power system operation and avoid voltage collapse from occurring. This paper presents the implementation of Particle Swarm Optimization (PSO) technique for solving ORPD problem considering multiple contingencies (N-m). The technique was implemented with the aim to improve voltage stability and minimize total transmission losses of the system. The IEEE 30-bus system was tested with generator outage in order to simulate the impact of disturbance to the power system transmission and distribution

Automatic attendance system using face recognition with deep learning algorithm

This project aims to develop an attendance system that is more efficient and convenient than traditional attendance methods currently used in schools and universities. Therefore, this paper proposes an automatic attendance system using face recognition. In this face recognition attendance system, the university does not need to install any additional devices in the classroom, which makes it a cost-effective system. The system consists of three parts: attendance system, student profile system, and training. First is the training stage where the student’s photo should be captured and stored in a separate folder. Second is the attendance system. Here the lecturer needs to take a photograph of the student and then upload it to the system. The system will automatically recognize the student’s face and store his/her name in an excel sheet (CVS file). The third system is the student’s profile. This system is to help the lecturer retrieve the student’s data by only capturing a picture of the student. A GUI has been made to simplify the usage of the system. The face recognition system has been developed using a combination of two deep learning algorithms: Multi-Task Cascaded Convolutional Neural Network (MTCNN) and FaceNet. To train the system, 908 pictures from 21 different students were collected and used, and 108 pictures were used for testing. The testing result showed 100% for face detection and 87.03% for face recognition
