Blind people are prone to sweep or knock whatever obstacle which pass before them during walking, subjecting them to risk of injury caused from fall. The aim of this project is to develop a smart cane with distance measurement system. The system comprise of an ultrasonic sensor as input and earphone as the output. Ultrasonic sensor is used to measure distance from the obstacle. Data is then sent to...
Agarwood, also known as Gaharu in Malaysia, is a fragrant and valuable international commodity harvested from Aquilaria and Gyrinops tree species. The quality of agarwood depends on many factors, such as the quality of its wood resin, smell and origin. Current methods for determining its quality rely on human experts. However, an automated approach would be more suitable for mass production. In this...
ECG refers to non-invasive bioelectrical recording of the heart. Under the clinical settings, the ECG is interpreted by cardiologists via conventional inspection techniques. The methods however are exposed to visual error which leads to inaccurate diagnosis of the heart condition. Hence, as an attempt towards an automated diagnostic system, the paper elaborates on arrhythmia modelling based on ECG...
This paper presents an evaluation of characteristic frequency features in healthy and diseased ECG via k-NN classifier. Initially, a total of 264 segment samples are obtained for healthy, bundle branch blocks, dysrhythmia cardiomyopathy conditions from the PTB Diagnostic ECG database. The signal is preprocessed to obtain the power spectral density. The characteristic frequency for each segment sample...
Each year, the number of stolen vehicle is on the rise. Usually, to prevent theft, a physical type countermeasure is used such as padlock, disk break lock and other more which is a preventive action but it is not enough safe. The objective of this study is to create a controllable system that can display the location of a vehicle using Global position system (GPS) to pin point the location and Global...
The paper elaborates on the correlation analysis between the proposed EEG sub-band spectral centroid amplitude with the established band power features. The study involves recording of resting EEG from 40 healthy university students. Initially, the EEG is pre-processed for noise removal and filtered into delta, theta, alpha and beta waves using band-pass filters. Next, the sub-band power spectral...
A current technology storage management system has an obvious weakness in the terminal data gathering because they contain no feature of real-time and automatic data retrieval. Store staffs have to check detail information manually or through the barcode system. Hence, human error may frequently happen due to incorrect information to the stock control or management control. Therefore, it is essential...
The paper discusses on the effects of Hamming and equiripple filters in the extraction of EEG sub-band spectral centroid frequencies. A total of 40 healthy male subjects have participated in the study. EEG signal sub-bands were filtered using Hamming and equiripple filters with similar frequency response characteristics. It has been observed that the mean difference and variance is very small for...
The main purpose of this paper is to design and develop an automatic rabbit droppings compost grinder using PIC microcontroller. The prototype developed by combined the grinder motor and water pump system which functions to blend and supply the parser liquid to the rabbit waste. The development of prototype consists of grinder motor, water pump, manure container, mixture of parser materials storage...
It has been a long debate on conventional psychometric test as benchmark of individual's intelligence quotient (IQ). However, recent studies in a variety of neurophysiological researches have been done to link intelligence with individual's brainwave pattern. Hence this paper proposes an intelligent approach to classify IQ via brainwave sub-band power ratio and artificial neural network (ANN). Fifty...
Cardiac arrhythmias refer to abnormal electrical activity of the heart which results in irregular heartbeat. This paper proposes a computerized method in detecting cardiac arrhythmias using a structurally optimized hybrid multilayered perceptron (HMLP) network. ECG samples in bipolar limb lead orientations have been obtained from PTB Diagnostic ECG database for healthy, cardiomyopathy, as well as...
Temperature monitoring play an important role in many processes especially in the livestock sector. Animal behavior usually depends on the temperature. In order to produce a good and healthy livestock animal, an environment monitoring is a must due to global warming and climate changes. These research applied LM35 temperature sensor as a main transponder to measure the temperature of rabbit cage environment...
Cardiac arrhythmia refers to any abnormal electrical activity in the heart that causes irregular heartbeat. Under clinical settings, the arrhythmias can be monitored non-invasively using the electrocardiogram (ECG). Although reliable, the method is still prone to error due to its dependence on visual interpretation. This paper proposes a computerized method for recognition of cardiac arrhythmia using...
Aquaponic has become an interesting model for private sector, aquaculture and environmental scientist because of many advantages that can be obtained. The word ‘Aquaponic’ refer to the integration of ‘hydroponic’ (growing plant/vegetable production without soil) with aquaculture (fish farming). The growth performance of comet goldfish (aquatic) against a hydroponic plant of Ipomoea aquatic (water...
The paper describes a robust approach to model cardiac arrhythmias using the hybrid multilayered perceptron (HMLP) network. Healthy, cardiomyopathy, as well as left and right bundle branch block electrocardiograms (ECG) was obtained from the PTB Diagnostic ECG database. The signals were initially pre-processed for noise removal and baseline correction. 24 morphological descriptors from the bipolar...
Vehicles' motion on roads causes road surface vibration. Road surface vibration induced by passing vehicles has been investigated by some researchers in attempt to obtain traffic data such as volume, speed, occupancy and vehicle types. This type of non-deterministic study of vibration signals employs parametric as well as non-parametric methods to explore important properties of the vibration signals...
Sub-band spectral centroid (SC) has been widely applied in audio and speech processing field. This paper highlights the SC feature as a new approach to evaluate human intelligence quotient (IQ). The study focuses on resting EEG of the left brain hemisphere. The SC feature is derived from Discrete Fourier Transform (DFT) of electroencephalogram (EEG) signals. Sub-band SCs are obtained for delta, theta,...
Cardiomyopathy is a progressive disease that affects the muscular walls of the heart. The resultant hypertrophic condition of the cardiac chambers alters the capability of the heart to contract which will then lead to deterioration of cardiac output. The abnormality can manifest itself in the form of an arrhythmic signal detectable by electrocardiogram (ECG). Hence, this paper proposes the hybrid...
This paper discusses on the brainwave sub-band characteristics for different intelligence groups based on electroencephalogram (EEG) power ratio technique. The EEG datasets have been collected from 50 healthy subjects for two sessions; at relaxed, closed eye (CE) state as reference and at cognitively-stimulated state. In the stimulated state, subjects need to answer the intelligence quotient (IQ)...
Deterioration of structure and function of heart muscle is indicative of a degenerative disease known as cardiomyopathy. As a result, the hypertrophic condition of the heart often revealed itself in the form of abnormal sinus rhythm that can be detected via an electrocardiogram (ECG). In order to reduce the risk of misinterpretation by cardiologists, a variety of computational methods have been suggested...
