Classification of agarwood oil using an electronic nose
(MDPI Publishing, 2010-05-06)Presently, the quality assurance of agarwood oil is performed by sensory panels which has significant drawbacks in terms of objectivity and repeatability. In this paper, it is shown how an electronic nose (e-nose) may be ... -
Modeling orthogonal and rectilinear mixed-modality projection of optical tomography for solid-particles concentration measurement
(Elsevier B. V., 2010-06)In optical tomography, light attenuation/scattering methods have been used to determine average solids concentrations in gas-solids flows. Derived from the Lambert-Beer law, the Mie theory forms the theoretical basis for ... -
The front-end hardware design issue in ultrasonic tomography
(IEEE, 2010-07)This paper explains the front-end hardware design for ultrasonic tomography. The ultrasonic tomography system presented in this paper uses a noninvasive sensing technique with transmission-mode approach for investigating ... -
Improved classification of Orthosiphon stamineus by data fusion of electronic nose and tongue sensors
(MDPI Publishing, 2010-09-28)An improved classification of Orthosiphon stamineus using a data fusion technique is presented. Five different commercial sources along with freshly prepared samples were discriminated using an electronic nose (e-nose) and ... -
Asynchronous brain machine interface-based control of a wheelchair
(Springerlink, 2011)A brain machine interface (BMI) design for controlling the navigation of a power wheelchair is proposed. Real-time experiments with four able bodied subjects are carried out using the BMI-controlled wheelchair. The BMI is ... -
J-integral evaluation in two dimensional interacting cracks
(Trans Tech Publications, 2011)This paper investigates crack interaction of multiple edge cracks in elastic solid finite body under pure Mode I loading. The cracks are located in parallel to another in 2D plate model. The stress intensity factors (SIFs) ... -
Fatigue failure analysis using the theory of critical distance
(Trans Tech Publications, 2011)This paper explores the initial potential of theory of critical distance (TCD) which offers essential fatigue failure prediction in engineering components. The intention is to find the most appropriate TCD approach for a ... -
Flow behavior characteristic for injection process using nano-yttria stabilized zirconia for micro metal injection molding (μMIM)
(Trans Tech Publications, 2011)Micro metal injection molding (μMIM) prior to conventional plastic injection molding (PIM) has become widely demanding due to its smaller size, more complex geometric surface and time consuming on its product. Metal and ... -
Detection of vocal fold paralysis and edema using time-domain features and probabilistic neural network
(Inderscience Publisher, 2011)This paper proposes a feature extraction method based on time-domain energy variation for the detection of vocal fold pathology. In this work, two different vocal fold problems (vocal fold paralysis and edema) are taken ... -
Combining spatial filtering and wavelet transform for classifying human emotions using EEG Signals
(Biomedical Engineering Society of the R.O.C., 2011)In this paper, we present human emotion assessment using electroencephalogram (EEG) signals. The combination of surface Laplacian (SL) filtering, time-frequency analysis of wavelet transform (WT) and linear classifiers are ... -
Computation of stress intensity factor for multiple cracks using singular finite element
(Trans Tech Publications, 2011)The simplification of two dimensional approaches in singular finite elements has promoted the method to be used in the formulation of stress intensity factor (SIF) of multiple cracks in finite body. The effect of shielding ... -
Hardware developments of an ultrasonic tomography measurement system
(International Frequency Sensors Association (IFSA), 2011-01)This research provides new technique in ultrasonic tomography by using ultrasonic transceivers instead of using separate transmitter-receiver pair. The numbers of sensors or transducers used to acquire data plays an important ... -

Classification of speech dysfluencies using LPC based parameterization techniques
(Springer Science+Business Media, LLC., 2011-01-20)The goal of this paper is to discuss and compare three feature extraction methods: Linear Predictive Coefficients (LPC), Linear Prediction Cepstral Coefficients (LPCC) and Weighted Linear Prediction Cepstral Coefficients ... -
Development of human sensory mimicking system
(American Scientific Publishers, 2011-02)Taste (gustatory) and smell (olfactory) are two of the five human senses apart from touch (somatosensory), vision and hearing (auditory). In human and many other vertebrate animals the sense of taste are often used with ... -
Gas hold-up profiles measurement using ultrasonic sensor
(Institute of Electrical and Electronics Engineers (IEEE), 2011-02)In this letter, we present a work carried out to measure gas hold-up profiles in a liquid column using a pair of ultrasonic sensors. The gas hold-up profiles from 1.85 to 7.7 mm in diameter are of interest in this ... -
Adaptive Neuro-Controller for three-axes attitude control of innovative satellite
(Science Academy Publisher, 2011-03)There exists so many disturbance torques in space which may deviate the satellite from the desired attitude. To overcome the effects of the disturbance torques some stabilization has to be provided to the satellite. This ... -
Performance comparison of the artificial neural network and the k-nearest nieghbor classifiers in classroom speech intelligibility prediction application
(Science Academy, 2011-03)Classroom speech intelligibility has become one of the major concerns in education nowadays. In any classrooms and educational facilities, an optimal speech intelligibility level is required to ensure that the listeners ... -
Reckoning of facial grimacing scheme for patient agitation in critical care
(Science Academy Publisher, 2011-03)Reckoning patient grimacing in Intensive Care Unit (ICU) is a crucial demand in checking routine procedure. Despite of detecting any physical change in the body of the patient, medical staff has to go up and down to the ... -
