We demonstrate experimentally on-chip-integrated quantum spectroscopy by generating biphotons in a LiNbO3 waveguide through spontaneous parametric down-conversion, and using signal photon detection in the NIR to study the dynamics of idler photons in the MIR.
An experimental study on the electromagnetic field (EMF) coupling to the inert instrumented bridge wires is reported in this work. The experimental studies are conducted on the S and X bands, as the hazards of electromagnetic radiation to ordnance (HERO) environment is maximum in these two frequency bands. The study was carried out with a metallic cylindrical body to study the resulting effects. In...
Ultra wideband (UWB) electromagnetic field (EMF) generation from portable sources has increased the threat of intentional EMI attacks on the civil and defense infrastructure. Various types of EIDs are used in a typical airborne system for applications like stage separation, firing of propulsion systems and triggering of warheads etc. The EIDs, potentially can be triggered when operating in an electromagnetic...
Recent advances in the brain computing technology have opened up novel paths for the development of various Brain-Computer-Interface (BCI) applications. It enables people to use the signals of BCI for silent communications, biometrics, security and to control various devices. Likewise, the progress in Smartphone technology facilitates everyone with a large number of applications including gaming,...
The fully connected conditional random field (CRF) with Gaussian pairwise potentials has proven popular and effective for multi-class semantic segmentation. While the energy of a dense CRF can be minimized accurately using a linear programming (LP) relaxation, the state-of-the-art algorithm is too slow to be useful in practice. To alleviate this deficiency, we introduce an efficient LP minimization...
Truncated convex models (TCM) are a special case of pair-wise random fields that have been widely used in computer vision. However, by restricting the order of the potentials to be at most two, they fail to capture useful image statistics. We propose a natural generalization of TCM to high-order random fields, which we call truncated max-of-convex models (TMCM). The energy function of TMCM consists...
In this paper, reflectance and transmittance of Silicon nanostructure array obtained from simulation of various textured structure has been presented. These nanostructures reduce the reflections and enhance the antireflection property of solar cells. We reviewed various fabrication methods used for nanoscale antireflection structures. Generally fabrication of nanoscale structure is done by two approaches:...
Today's E-commerce is totally based upon the opinions of the customers. There are lots of opinions on the internet about any product. Now a day's people are using roman words to express their reviews. The main aim of this paper is to find the polarity of any item. In this paper firstly Roman opinion words are converted into corresponding English opinion words then applied Jaccard Similarity algorithm...
Biosensor is an analytical device used to detect the biological analyte, which can be antibodies enzymes cells or biomolecules. Biosensors have many applications like in environmental monitoring, biomedical research, and healthcare. In this paper we have proposed a multichannel nanocavity coupled photonic crystal biosensor having waveguides and nanocavities in the hexagonal lattice of rods of Si in...
Identity verification of a person always considered a wide research area. In past, Identity of a person verified by traditional token-based or knowledge-based system but in recent year's bio-metrics traits like face, finger, iris, palm print etc. become a key technology for identity verification. Palm print is also the one bio-metric trait that can be used for the efficient identification. Palm print...
A node is an intersection point that can generate, receive, store or transmit data along distributed network routes and allows us to analyze the data at a particular point. In a network node, each sensor has several parts such as transceiver with an internal or connection to an external antenna, micro controller, electronic circuits for interfacing sensors and energy source. The scaling of single...
This paper reports on the synthesis of newly introduced conformal shaped Triangular Prism Antenna array (TPA). For the generation of multi beam pattern, Flower Pollination algorithm (FPA) is used. To get the beam in an azimuthal plane at 00 and 1800, optimization is done by varying various controlling parameters such as antenna excitation, the distance between antenna elements and the number of antenna...
Sampark is machine translation system providing translations among nine pairs of Indian languages. Machine translation system is a class of natural language processing applications that is far more complex and highly compute intensive in nature. As the load on the deployed system increases, optimization becomes a challenge. Caching is one of the available options to improve the performance of a software...

The proposed design of pcf is composed silica material, design and simulated by finite difference time domain software(FDTD)method, Using this structure, the pcf with confinement loss lass then −0.1db/km over a wide range of wavelength from 0.8–2μm and zero...
Recognition of handwritten Roman characters and numerals has been extensively studied in the last few decades and its accuracy reached to a satisfactory state. But the same cannot be said while talking about the Devanagari script which is one of most popular script in India. This paper proposes an efficient digit recognition system for handwritten Devanagari script. The system uses a novel 196-element...
To meet the growing demand of food and other agriculture dependent commodities, crop producers in whole world are putting extra efforts to raise the production. They utilize chemicals, supplements, agro machinery, and special techniques without understanding the basic needs of soil ecosystem. It hampers the soil in long term conditions. Therefore to understand the actual needs of soil real time sensing...
