This paper compares the performance of two clustering methods; DPClus graph clustering and hierarchical clustering to classify volatile organic compounds (VOCs) using fingerprint-based similarity measure between chemical structures. The clustering results from each method were compared to determine the degree of cluster overlap and how well it classified chemical structures of VOCs into clusters....
Background Effective management of patients with diabetic foot infection is a crucial concern. A delay in prescribing appropriate antimicrobial agent can lead to amputation or life threatening complications. Thus, this electronic nose (e-nose) technique will provide a diagnostic tool that will allow for rapid and accurate identification of a pathogen. Results This study investigates the performance...
Volatile organic compounds (VOCs) or volatile metabolites are small molecules and comprise a chemically diverse group of organic compounds, with a low molecular weight in the range of approximately 500 Daltons. They have low boiling points and high vapor pressure under ambient conditions. VOCs contribute only a small proportion of the metabolites produced by living organisms, however because of their...
Emotional Stress Indicator (ESI) kit is a wearable sensor device that used to measure the human stress level. Many people out there do not aware about their level of stress that will give a big impact in their life. So this study is aimed to design and develop an Emotional Stress Indicator (ESI) kit which can display stress level among people. This ESI kit is constructed based on human skin resistance...
Epilepsy is one of the most common neurological disorders causing from repeating brain seizures that are the result of the temporal and sudden electrical disturbance of the brain. Electroencephalogram (EEG) signal plays an important role in the diagnosis of epilepsy. This project proposed to develop a system that can detect epilepsy based on EEG signal using artificial neural network. Discrete Wavelet...
Image processing plays an important role in medical diagnosis. In this paper, a brain tumor detection method based on cellular neural networks (CNNs) is proposed. Brain tumor is an abnormal growth of cells inside the skull. To examine the location of tumor in the brain, Magnetic Resonance Imaging (MRI) is used. Radiologists will evaluate the grey scale MRI images. This procedure is really time and...
This study aim to synthesize bioceramic from Paphia undulata shell by using dry technique in order to proposed new bioceramic for human bone repair application. The clam shells obtained from the fisherman of Kuala Perlis coast were turned into a fine powder using an agate mortar. Since the clam shells contain high percentage of calcium carbonate, calcium carbonate powder turned to calcium oxide (CaO)...
In identifying the location of tumors in the liver, eddy current characteristics analysis can be applied since the conductivity value of normal tissue and tissue with tumors are different, which are 2.88 mS/cm and 5.33 mS/cm, respectively at 1 MHz. In this letter, simulation based on small scale magnetic induction system was carried out. The system consists of a 10 cm diameter sensor jig and a cone...
In Magnetic Induction Tomography (MIT) or Electromagnetic Therapy system, excitation coil is applied with AC source in generating the electromagnetic (EM) field which then propagate and penetrate the object located in the region of interest (ROI). However, instead to the target object, the fields also propagate around the coil and create interference to the nearby circuit which contributes noise to...
Medical diagnosis is one of the most important procedure in which image processing are usefully applied. In this paper, a pneumonia symptoms detection method based on cellular neural networks (CNNs) is proposed. The CNN design is characterized by a virtual template expansion obtained through a multistep operation. It is based on linear space invariant 3 × 3 templates. The proposed design is capable...
