This paper presents acetone vapor sensing properties of WO(3) thick films. In this work, the WO(3) thick films were prepared by standard screen-printing method. These films were characterized by X-ray diffraction (XRD) measurements, and scanning electron microscopy (SEM). The acetone vapor sensing properties of these thick films were investigated at(More)
The manuscript presents Marathi connected word speech recognition system. The system is implemented using Mel-frequency Cepstral Coefficient (MFCC) feature extraction technique and Continuous Density Hidden Markov Model (CDHMM). Initially, recorded speech signals of connected words are segmented into words using speech segmentation algorithm. The speech(More)
This paper reports the synthesis and liquid petroleum gas (LPG) sensing properties of nano-sized cadmium oxide (CdO). The nano-sized CdO powder was successfully synthesized by using a chemical co-precipitation method using cadmium acetate and the ammonium hydroxide, as starting materials and water as a carrier. The resulting nano-sized powder was(More)
Devnagari (Marathi) is an Indo-Aryan language and has a number of speakers all around the world. Marathi language has gained acceptability in the media & communication and therefore deserves to have a place in the growing field of automatic speech recognition. This manuscript describes the automatic speech recognition system that recognizes Marathi(More)
This paper focuses on the strength of uPVC and FRP Materials. These material shows differ strength on same application. The uPVC inspection chamber ultra450 is used for light vehicle road traffic and it specifically facing or suffers from breakages when the vehicle passing over it. Whenever the light or small utility vehicle (SUV) about 14 to 16 tonne(More)
Thin films of copper indium diselenide (CIS) were prepared by chemical bath deposition technique onto glass substrate at 60C. The studies on composition, morphology, optical absorption, electrical conductivity and structure of the films were carried out. Characterization includes X-ray diffraction (XRD), Scanning electron microscopy (SEM), Atomic force(More)
A series of novel fluoroionophore bearing derivatives of benzo-15-crown-5 were synthesized by the amination of benzo-15-crown-5 followed by condensation with different quinones in the presence of titanium tetrachloride (TiCl4 ) and 1,4-diazabicyclo-[2.2.2]octane. The compounds were characterized by infrared, (1) H and (13) C nuclear magnetic resonance, mass(More)
The low carbon steel (LCS) electrodes were polarized under cyclic voltammetric conditions in sodium oxalate solution at room temperature in order to understand the different processes that occur at the electrode surface. This study suggests that, a continuous dissolution of the LCS electrode occurs in oxalate solution. In order to understand the observed(More)
The polypyrrole (PPY) coatings were electrochemically synthesized on low carbon steel (LCS) substrates by cyclic voltammetric method from an aqueous solution of sodium oxalate. The corrosion protection performance of PPY coatings on LCS were studied in different corrosive environments such as, aqueous 3% NaCl, 0.01 M Na2SO4 and tap water. This corrosion(More)
Drilling of glass fibre reinforced plastic (GFRP) composite is different from metallic materials due to its mechanical properties. The drilling of this material may generate delamination of drilled holes on workpiece. The purpose of this paper is to investigate the influence of the cutting parameters, such as cutting speed and feed rate, point angle of(More)
