In this paper, we present a method of concealing an image, individually, on multiple frames of a video, using DWT Algorithm. Our aim, for this research, is to obtain a colored output image, as a watermark, on each frame of the video, and to do so, color component decomposition has been performed. Using DWT technique, we have successfully applied image(More)
We study multicarrier on-off keying (MCOOK) for fast frequency-hopping (FFH) multiple-access systems. The performance of a sub-optimum receiver is analyzed for Rayleigh fading channels and a closed form expression for bit error rate (BER) has been derived for the binary case. We find that the number of chips per symbol required to optimize the performance(More)
Nanotechnology is a cutting-edge field of science with the potential to revolutionize today's technological advances including industrial applications. It is being utilized for the welfare of mankind; but at the same time, the unprecedented use and uncontrolled release of nanomaterials into the environment poses enormous threat to living organisms. Silver(More)
Abiotic stress is one of the severe stresses of environment that lowers the growth and yield of any crop even on irrigated land throughout the world. A major phytohormone abscisic acid (ABA) plays an essential part in acting toward varied range of stresses like heavy metal stress, drought, thermal or heat stress, high level of salinity, low temperature, and(More)
Power consumption is one of the major issues in today's general life. But semiconductor is a great solution of this power consumption. If we success to use semiconductors in well manner then we can reduce power consumption. Peltier module is one of the best solutions for this. Air-conditioner carry 2000 or 3000 Watt power and cloth iron takes minimum 750(More)
Guar (Cyamopsis tetragonoloba L. Taub) is a drought-tolerant multipurpose cash crop. A rapid regeneration system has been developed for four Indian guar genotypes. Investigations were carried out to assess the effect of different growth regulators and their combinations on a variety of explants such as the embryo, cotyledons, and cotyledonary nodes for(More)
Present work is an in depth study to detect flames in video by processing the data captured by an ordinary camera. Previous vision based methods were based on color difference, motion detection of flame pixel and flame edge detection. This paper focuses on optimizing the flame detection by identifying gray cycle pixels nearby the flame, which is generated(More)
The aim of this research is to find out how the electricity consumption can be reduced by reduction in the heat load. In furtherance of our aim, a cold storage has been taken for study and with the help of insulation in the cold storage; heat load has been reduced as it lowers the temperature. Several methods and materials have been discussed in this(More)
In this research work, the working of solar air-conditioning system has been considered. This paper includes construction wise and parameter wise analysis of this complete system specially designed for Indian climate. The power consumption is a very major issue in India and the paper solves the problem of power consumption especially in the case of(More)
