Design of Microstrip Patch Antenna using Ads Tool

The investigation of microstrip fix reception apparatuses has gained incredible ground as of late. Contrasted and regular receiving wires, microstrip fix radio wires have more preferences and better prospects. They are lighter in weight, low volume, minimal effort, low profile, littler in measurement and simplicity of creation and congruity. Also, the microstrip fix recieving wires can give double and roundabout polarizations, double recurrence operation, recurrence deftness, expansive band-width, encourage line adaptability, pillar filtering omnidirectional designing. In this paper we examine the microstriprecieving wire, sorts of microstrip radio wire, nourishing strategies and utilization of microstrip fix reception apparatus

Face Recognisition Using PCA Method

this paper essentially addresses the working of face acknowledgment framework by utilizing Principal Component Analysis (PCA). PCA is a factual approach utilized for diminishing the quantity of factors in face acknowledgment. In PCA, each picture in the preparation set is spoken to as a direct blend of weighted eigenvectors called eigenfaces. These eigenvectors are acquired from covariance network of a preparation picture set. The weights are discovered subsequent to choosing an arrangement of most applicable Eigenfaces. Acknowledgment is performed by anticipating a test picture onto the subspace crossed by the eigenfaces and afterward characterization is finished by measuring least Euclidean separation. Various tests were done to assess the execution of the face acknowledgment framework

Gender Classification by Speech Analysis

-Gender classification is widely used in automatic speech recognition systems to recognize a speaker speaking continuously in any language. This work aims at analysing speech signals based on some parameters so as to predict the gender of the speaker. This paper comprises of male and female voice samples which were collected to form a database. Parameters such as mean, variance and standard deviation were determined to help in classifying the gender of the speaker

Not AvailableSpatial heterogeneity of a river basin increases the predicting uncertainty of streamflow using hydrological models, and for such river basins calibration and prediction become a challenge. For a large and low flow–producing river basin like the Pennar basin of India, single-site calibration may ignore spatial heterogeneity, which leads to the use of a multiple-site calibration approach. The present study used Soil and Water Assessment Tool (SWAT) model to develop a real-world numerical model for predicting streamflow in a large, low runoff–producing river basin and evaluated the performance of the model under single-site and multiple-site calibration approaches. Under multiple-site approach, the large basin was divided into smaller subbasins, and the calibrated parameters were sequentially applied to the entire basin, and so local conditions were incorporated very effectively into the calibration process. The results demonstrated the superiority of a multiple-site calibration over a single-site calibration approach in predicting streamflow. The overall improvement of model performance in predicting streamflow using multiple-site approach over single-site approach reached as high as 133% during calibration and 140% during validation, as observed at the basin outlet (Chennur station). It was also observed that, within the basin, precipitation contributed only 15.8% to surface runoff, 2.6% to total aquifer recharge, and 69.3% to evapotranspiration. Uncertainty analysis indicated that more than 64% of the observed streamflow was bracketed by a 95% prediction uncertainty (PPU) band under the multiple-site approach. Thus, the multiple-site calibration approach demonstrated its ability to improve model performance by capturing the heterogeneity of a low runoff–producing basinNot Availabl

High indium non-polar InGaN clusters with infrared sensitivity grown by PAMBE

Studies on the optical properties of InGaN alloy of relatively higher indium content are of potential interest to understand the effect of indium content on the optical band gap of epitaxial InGaN. We report the growth of self assembled non-polar high indium clusters of In0.55Ga0.45N over non-polar (11-20) a-plane In0.17Ga0.83N epilayer grown on a-plane (11-20) GaN/(1-102) r-plane sapphire substrate using plasma assisted molecular beam epitaxy (PAMBE). Such structures are potential candidates for high brightness LEDs emitting in longer wavelengths. The high resolution X-ray diffraction studies revealed the formation of two distinct compositions of InxGa1-xN alloys, which were further confirmed by photoluminescence studies. A possible mechanism for the formation of such structure was postulated which was supported with the results obtained by energy dispersive X-ray analysis. The structure hence grown when investigated for photo-detecting properties, showed sensitivity to both infrared and ultraviolet radiations due to the different composition of InGaN region.

Highly conducting polymer electrolyte-ionic liquid and porous carbon material for sandwich electric double layer capacitor

Due to various useful properties of polyethers, the prime objective of present paper is to develop an efficient supercapacitor based on high conducting polymer electrolyte and carbon based materials. To develop such films Polyvinylidene fluoride co-hexafluoropropylene (PVDF-HFP) polymer doped with ionic liquid (IL) 1-ethyl-3-methylimidazolium thiocyanate has been prepared using solution cast technique. The detail studies of polymer electrolyte with optimized value of IL: PVDF-HFP i.e. (80:20) we have reported elsewhere. For electrodes, cobalt enriched porous carbon material has been synthesized and characterized in detail. A sandwiched type electric double layer supercapacitor (EDLC) has been fabricated using maximum conducting polymer-IL film which shows ultra-high capacitance of 294 F/g at room environmental condition. This work successfully demonstrates the suitability of polymer electrolyte in developing highly efficient energy devices
