The pH-sensitive gold nano hydrogel based on itaconic acid, acrylic acid and triethylene glycol (GIAT) has been prepared by free radical polymerization viz. organic solventless approach with different monomer ratios. The nature of bonding and structural identification of GIAT hydrogels were characterized by FT-IR spectroscopy. The surface morphology of gold gel was examined using scanning electron microscopy (SEM). In addition, transmission electron microscopy (TEM) was used to identify the size of gold nano particles. The in vitro biocompatibility of GIAT hydrogel has been evaluated in 3T3 fibroblast cell lines. The obtained results show that gold nano particle incorporated hydrogel possess ~ 99% of cell proliferation. Followed by, the impact of gold nano particles on swelling, surface morphology was studied. The consecutive preparation of hydrogel, effect of different pH conditions, and stoichiometry of monomeric units have also been discussed. The degree of swelling was measured in carbonate buffer solutions for 24 h period with varying pH such as 1.2, 6.0, 7.4 and 10.0. The obtained results showed that the stoichiometry of itaconic acid and gold nano particles plays an essential role in modifying the nature of GIAT polymeric hydrogels. In conclusion, promising Au-nano incorporated pH-sensitive bio polymeric hydrogels were prepared and characterized. The unique properties of these Au-nano hydrogel make them attractive use in biomedical applications. © 2017 Elsevier B.V.

The in situ ZrB2/AA2014 composite is being extensively fabricated by the exothermic salt-metal reaction method. The potassium hexafluorozirconate (K2ZrF6) and the potassium tetrafluoroborate (KBF4) were used to synthesize the ZrB2 particles through the salt reaction route The developed insitu aluminium matrix composites were examined for the impending improved mechanical properties such as macro hardness, micro hardness and tensile strength. The developed composites were characterized by optical microscope and X-ray diffraction. X-ray diffraction ensures the formation of ZrB2 phases and also confirms that no other reaction outgrowth compounds are traced in the composites. Optical micrographs display that the particles are nearly uniformly distributed in the matrix alloy. The increase in weight percentage of zirconium diboride particles enhances the hardness and the tensile strength of the composite. © 2017 Elsevier Ltd. All rights reserved.

This paper deals with an experimental verification of full bridge resonant inverter fed induction heating system. The switches operate in soft commutation mode and serves as a high frequency generator. The operating frequency is automatically adjusted to maintain a small constant lagging phase angle under load parameter variation. The output power is controlled using the asymmetrical voltage cancellation technique. The full bridge series- parallel resonant tank is designed without the use of output transformer. This results in an increase of the net efficiency of the induction heating system. This system has an advantage like reduced volume and switching losses. Steady state analysis of the inverter operation is presented. The circuit models are developed for simulation studies. The results of simulation and hardware are presented. Experimental results are compared with simulation results. © 2012 Pillay Engineering College.

Obtaining optimal power flow solution is a strenuous task for any power system engineer. The inclusion of FACTS devices in the power system network adds to its complexity. The dual objective of OPF with fuel cost minimization along with FACTS device location for IEEE 30 bus is considered and solved using proposed Enhanced Bacterial Foraging algorithm (EBFA). The conventional Bacterial Foraging Algorithm (BFA) has the difficulty of optimal parameter selection. Hence, in this paper, BFA is enhanced by including Nelder-Mead (NM) algorithm for better performance. A MATLAB code for EBFA is developed and the problem of optimal power flow with inclusion of FACTS devices is solved. After several run with different initial values, it is found that the inclusion of FACTS devices such as SVC and TCSC in the network reduces the generation cost along with increased voltage stability limits. It is also observed that, the proposed algorithm requires lesser computational time compared to earlier proposed algorithms. © 2013 ISA.

Multilevel inverters are becoming more popular for various industrial applications due to higher voltage operating capability, lower dv/dt’s and to synthesize desired output voltage. This paper focus on Phase Disposition PWM (PD-PWM) technique for asymmetric multi-level inverter in order to produce a trinary output. Carrier based level shifted PWM technique which includes Phase Disposition (PD-PWM), Phase Opposition Disposition (PODPWM) and Alternative Phase Opposition Disposition (APOD-PWM) is implemented to generate switching signals and to improve the performance of output voltage with less number of switches in cascaded multilevel inverter (CMLI). To overcome the limitation of semiconductors current and voltage ratings in high power applications, Cascaded H-Bridge connection is often considered as effectual solution which leads to increase of inverter efficiency. The proposed Variable Frequency PDPWM (VF-PDPWM) technique is confirmed the minimized Total Harmonic Distortion (THD) and Switch utilization is substantially reduces 33.33% of the Constant Frequency PDPWM (CF-PDPWM) switching technique. A detailed study of the technique was carried out through MATLAB /SIMULINK for THD and Switch utilization. © Research India Publications.

JPEG is one of the widely used image formats in digital image processing. The analysis and the discovery of JPEG Image compression methods contribute a major significant part in digital images forensic examination. In recent years, the JPEG images can be compressed several times such as single, double and multiple times, but if the compression is applied to same image again and again without estimation of the quantization results, it becomes very complicated to detect JPEG image compression results. Since same quantization matrix is used for several number of compression process, the results of quantization has to be analyzed in each step of compression to solve the above problem. Moreover, error values in the quantized matrix and resizing of the image samples are not carried out effectively. In order to overcome these problems, in this research work, compressed images are resized using improved seam covering method and estimation of quantization matrix results for single and double DCT compression methods using Fuzzy Neural Network (FNN) to investigate the error values. From FNN, the quantization matrix result is examined in DCT compression methods in order to differentiate the singly and doubly compressed images, which results quantization error values in the compression methods. Wide-ranging of experiments shows that the proposed DCT compression with FNN have higher detection rate for double and single JPEG compression successfully when compared with the existing DCT compression methods extensively. © 2014 Praise Worthy Prize S.r.l.-All rights reserved.

This study examines using an Artificial neural network to design pre and post Tsunami classification model with real time sensors placed at different location and at different depths. Using wavelet based denoising scheme artifacts in the sensor values have been excluded. The classification of the tsunami characteristics by means of "Neural Network" is executed for the first time in the literatures and academic researchers in Bay of Bengal. Based on the results from this study, it can be concluded that the testing performance of NN approach can be refined when the model is trained by BPN(Back propagation Neural Network) algorithm. The real time physiochemical parameters such as conductivity, salinity, pressure, temperature and dissolved oxygen were used for training the network and the output pattern is observed. © 2012 EuroJournals Publishing, Inc.

Subsynchronous Resonance (SSR) is a potential problem in power systems having series compensated transmission lines. Flexible AC Transmission Systems (FACTS) Controllers are widely applied to mitigate Subsynchronous Resonance (SSR). A long transmission line needs controllable series as well as shunt compensation for power flow control and voltage regulation. This can be achieved by suitable combination of passive elements and active FACTS controllers. In this paper, series passive compensation and shunt active compensation provided by a static synchronous compensator (STATCOM) connected at the electrical center of the transmission line are considered. It is possible to damp subsynchronous resonance (SSR) caused by series capacitors with the help of an auxiliary subsynchronous damping controller (SSDC) on STATCOM. The objective of this paper is to investigate the SSR characteristics of the system and mitigation of SSR with STATCOM SSDC. The analysis of SSR with STATCOM is carried out based on Eigen value analysis. The study is performed on IEEE First Benchmark Model (FBM). © Research India Publications.

This paper reviews some of the recent signal conditioning and Interface circuits for the capacitive type sensors. This paper gives the brief idea of advantages and limitations of interface circuits for the various capacitive sensors. The sensor output may be either current or voltage but it has to be converted to the desired output range only by the signal conditioning circuit. Signal conditioning circuits provides the analog output in the desired range; this can be converted to digital through Analog to Digital converter. The signal conditioning circuit should able to produce not only the convenient of output voltage or current levels but it has to provide the isolation, impedance matching, linearization with the input, proper gain adjustment with the amplification, filtering of unwanted signals, etc. Here we reviewed the four different methodologies of the proposed signal conditioning and interfacing circuits with its advantageous and limitations. © 2005 - 2012 JATIT & LLS.
