10.11591/ijra.v4i4.pp243-253
Khan Badshah , Qin Yongyuan
This paper discusses the techniques of attitude, velocity ad position estimation from GNSS carrier phase measurements, and investigates the performance of the lower precision MEMS-based INS/GNSS system based on carrier phase measurements. Double differenced carrier phase measurements provide more accurate velocity and position estimation compared to code and Doppler measurements. However, integer ambiguity is required to be removed for precise positioning. Multiples antennae approach is used to derive the attitude information from carrier phase measurements in order to control the large initial misalignment angles for initialization of the integration process or to utilize during benign dynamics. Lever arm effect is considered to compensate for the separation of GNSS antenna and IMU location. The derived three GNSS observables are used to correct the INS through optimal Kalman filtering in a closed loop. Simulation results indicates the effectiveness of the integrated system for airborne as well as for land navigation vehicles.

Using Deep Learning for Human Computer Interface via Electroencephalography

10.11591/ijra.v4i4.pp292-310
Sangram Redkar
In this paper, several techniques used to perform EEG signal pre-processing, feature extraction and signal classification have been discussed, implemented, validated and verified; efficient supervised and unsupervised machine learning models, for the EEG motor imagery classification are identified. Brain Computer Interfaces are becoming the next generation controllers not only in the medical devices for disabled individuals but also in the gaming and entertainment industries. In order to build an effective Brain Computer Interface, it is important to have robust signal processing and machine learning modules which operate on the EEG signals and estimate the current thought or intent of the user. Motor Imagery (imaginary hand and leg movements) signals are acquired using the Emotiv EEG headset. The signal have been extracted and supplied to the machine learning (ML) stage, wherein, several ML techniques are applied and validated. The performances of various ML techniques are compared and some important observations are reported. Further, Deep Learning techniques like autoencoding have been used to perform unsupervised feature learning. The reliability of the features is presented and analyzed by performing classification by using the ML techniques. It is shown that hand engineered ‘ad-hoc’ feature extraction techniques are less reliable than the automated (‘Deep Learning’) feature learning techniques. All the findings in this research, can be used by the BCI research community for building motor imagery based BCI applications such as Gaming, Robot control and autonomous vehicles.

Lusi Komala Sari , Bede Blaise Chukwunyere Onwuagboke
Life in heaven is the hope of all religious human. Yet, to reach the paradise as promised to all faithful is not an easy road. It needs the balance of earthly life and hereafter’s life to reach the place which is promised by God. The drama Robohnya Surau Kami (RSK) created by dramatist Hermana HTM which is adapted from a short story written by A.A. Navis conveys the aforementioned. Using descriptive technique to analyze Drama RSK it is found that the drama script is created by structural elements as other literary works. The social-religious theme presented in flashback plot made this drama script to heave the readers’ imagination upward. The dialogue which made the gradation of character of each character in the drama brings out the uniqueness of Drama RSK. Unfortunately, the presentation of such an interesting script was poorly supported by various means of literary and dramatics that appear blurred. Despite this, the drama revealed pragmatic view which symbolizes real life situations full of religious and moral lessons for edifying religious and good social life in the society.
