Technological evolution in bio-signal processing has enabled computer-based analysis of ECG which is an adjunct to the doctor in terms of feature extraction and diagnosis. However, acquisition and reliable parameter extraction of ECG signals using a computer based system is extremely susceptible to power line interference. 50 Hz active analogue notch filter is used to trim down hum in such applications. An attempt has been made to design various 50 Hz active notch-filter topologies in P-spice. Based on their amplitude and phase response, add-on notch filter hardware is developed and used with real-time computer based ECG system. The amplifier system includes biosensors, cascaded amplifiers, right leg drive circuits, active filters and 50 Hz notch filters. Analogue output of amplifier system is interfaced to the computer for recording and analysis. Thus a computer based compact and enhanced signal acquisition system is developed that yields online ECG of greatest clinical use. Copyright © 2013 Inderscience Enterprises Ltd.

We report a study on the carbon ion beam induced modifications on optical, structural and chemical properties of polyallyl diglycol carbonate (PADC) commercially named as CR-39 and Polyethyleneterepthalate (PET) polymer films. These films were then irradiated by 55MeV C 5+ ion beam at various fluences ranging from 1×10 11 to 1×10 13 ions/cm 2. The pristine as well as irradiated samples were subjected to UV-Visible spectral study (UV-Vis), Photoluminescence (PL), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. It has been found that ion irradiation may induce a sort of defects in the polymers due to chain scission and cross linking as observed from PL spectral study. It is revealed from UV-Vis spectra absorption edge shifted towards longer wavelength region after irradiation with increasing ion fluence. This shift clearly reflects decrease in optical band gap. The XRD study indicates the gradual decrease in intensity in case of PADC with increasing ion fluence. However, the intensity pattern increased in case of PET at fluence of 10 11 ion/cm 2 then decreased with further increase in fluence. Crystalline size of PADC was found to be decreasing gradually with increase of ion fluence. Whereas, the crystalline size of PET films found to increase with lower fluence and decreases with higher ion fluence. FTIR spectrum also shows the change in intensity of the typical bands after irradiation in the both the polymers. The results so obtained can be used successfully in heavy ions dosimetry using well reported techniques. © 2012 Elsevier Ltd.

A classification technique is an organized approach for building classification model from given input dataset. The learning algorithm of each technique is employed to build a model used to find the relationship between attribute set and class label of the given input data. Presence of irrelevant information in the data set reduces the speed and quality of learning. The technique of feature selection reduces the amount of data needed and execution time and it also improves the accuracy for prediction in the classification problem. In this paper we have modified K- Nearest Neighbor algorithm with relevant feature selection which selects the relevant features and removes irrelevant features of the dataset automatically.

ZnCuTe nanowires have been successfully synthesized via template-assisted one step electrodeposition technique from an aqueous solution of zinc sulphate (ZnSO 4.7H 2O), copper sulphate (CuSO 4. 5H 2O) and tellurium oxide (TeO 2) at room temperature (303 K). Nanowires of diameter 200, 100 and 50 nm have been synthesized on copper and indium tin oxide coated glass substrates using track-etch polycarbonate membranes (Whatman). The morphologies and structures of electrodeposited ZnCuTe nanowires were characterized by Scanning electron microscopy (SEM) and X-ray diffraction (XRD). SEM confirmed the formation of nanowires and reveal that the morphologies of nanowires have diameter equal to the diameter of the templates used. The XRD pattern have shown a preferential growth of ZnCuTe nanowires along the (119) direction and the structure corresponding to hexagonal structure. Energy dispersive X-ray analysis confirmed that the zinc copper telluride nanowires are constituted of elements Zn, Cu and Te. © Springer Science+Business Media, LLC 2011.

Polymer electrolytes are an important component of many electrochemical devices. Researchers have carried out a significant work for the development of polymer electrolytes. This paper reviews the recent developments in the area of polymer electrolytes using aqueous and nonaqueous-based natural polymers for developing a cheaper, ecofriendly, biodegradable, and widely used electrolytes as a substitute for existing synthetic polymer electrolytes. This paper also encompasses the merits and demerits of the different natural polymers used by the researcher. There is a scope to develop a nonaqueous-based natural polymer electrolyte as an alternate for synthetic polymer electrolyte for batteries and other electronic devices. © 2011 Springer-Verlag.
