Current methods for the accurate diagnosis of osteoarthritis (OA) based on magnetic resonance imaging and enzyme-linked immunosorbent assay method are highly sensitive and specific but require specialised laboratory facilities and highly trained operators to obtain a definitive result. A quartz crystal microbalance (QCM) immunosensor has been developed to(More)
Silver nanoparticles have been used in various fields, and several synthesis processes have been developed. The stability and dispersion of the synthesized nanoparticles is vital. The present article describes a novel approach for one-step synthesis of silver nanoparticles-embedded chitosan particles. The proposed approach was applied to simultaneously(More)
Surface acoustic wave (SAW) devices are key components for sensing applications. SAW propagation under a periodic grating was investigated in this work. The theoretical method used here is the space harmonic method. We also applied the results of SAW propagation studied in this work to design a two-port resonator with an Al grating on ST-cut quartz. The(More)
A shear horizontal surface acoustic wave (SH-SAW) sensor coated with polyaniline (PANI) was investigated in this study. The frequency shift of SH-SAW was measured for the response to ammonia in this study. The temperature effect was also discussed in order to find the suitable temperature of operation. The response of the SH-SAW sensor immediately responded(More)
The parts-per-billion-level nitric oxide (NO) gas sensing capability of a copper-ion-doped polyaniline/tungsten oxide nanocomposite (Cu(2+)/PANI/WO3) film coated on a Rayleigh surface acoustic wave device was investigated. The sensor developed in this study was sensitive to NO gas at room temperature in dry nitrogen. The surface morphology, dopant(More)
This paper presents a novel intelligent data mining technique to estimate the optical properties of touch panel (TP) with different layers coating. The neural network (NN) model is developed to be the intelligent tool for the data analyzer. The new computational method based on well-trained NN's weights is used to analyze the influencing factors of TP(More)
Osteoarthritis (OA) is a chronic disease that often occurs in the elderly population. Currently, the most common methods for diagnosing OA are radiographs and enzyme-linked immunosorbent assay (ELISA) method which are specific but require specialized laboratory facilities and highly trained personal. In this work, it developed a user friendly and(More)
The paper presents an intelligent control mechanism for the ITO bar's resistance of touch panel (TP). The artificial neural network is used to catch the complex relationship between bar's resistance and its relevant manufacturing parameters during the printing and etching processes. An effective and accurate manufacturing mechanism of ITO bar is expected to(More)
This paper presents the chromatic aberration estimations of touch panel (TP) film by using quasi-Newton neural networks. The data of TP film with one layer coating was studied and simulated. Through the training of neural network, the complex relationship between the chromatic aberration, i.e., L.A.B. values, and the relative parameters of TP decoration(More)
