The advanced development in wireless sensor networks can be used in monitoring various parameters in agriculture. Due to uneven natural distribution of rain water it is very difficult for farmers to monitor and control the distribution of water to agriculture field in the whole farm or as per the requirement...

Abstract-Sample Rate Conversion(SRC) and channelization are the two necessary tasks to be implemented for the design of a radio receiver. For a multi-standard software radio with a very high intermediate frequency(IF), which is of the order of 80MHz and above, the implementation of a sample rate converter...

Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message. Steganography is a form of security through obscurity. Steganography algorithms uses cover media such as text, image, audio and...

Though optical fibres have many advantages, they have noticeable disadvantages as well. So there is a need to look for other alternatives. This paper explores the penetration phenomenon of the light through some daily use products like milk and oil. Some of the light will be absorbed when passed through...

In this paper a digital image watermarking based on 3 level discrete wavelet transform (DWT) is presented & compare it with 1 & 2 levels DWT. In this technique a multi-bit watermark is embedded into the low frequency sub-band of a cover image by using alpha blending technique. During embedding, watermark...

Wireless communication systems are evolving to- ward multi functionality. This multi functionality provides users with options of connecting to different kinds of wire- less services for different purposes at different times. It is highly desirable to develop single radiating element having capabilities...

Facial expression recognition is necessary for designing any human-machine interfaces. Facial expression plays an important role in the recognition of human emotions and non verbal communication. Human face is a rich and powerful source of communicative information about human behavior. In this dissertation...

Automatic Speech Recognition (ASR) system performs well under restricted conditions but the performance degrades under noisy environment. Audio-visual features play an important role in ASR systems in presence of noise. In this paper Oriya isolated digit recognition system is designed using audio visual...

Energy Efficiency Policy has been identified as a measure to tackle climate change related issues globally. SEAD is developed to promote the multi-country collaboration and for exchange of information and learnings on energy efficiency. To strengthen and nourish the energy efficiency movement, Government...

Power quality is an issue that is becoming increasingly important to electricity consumers at all levels of usage. Sensitive power electronic equipment and non-linear loads are widely used in industrial, commercial and domestic applications leading to distortion in voltage and current waveforms. The...

This paper presents conventional Power control method for Separately Excited DC motor using specifically designed simulation software package PSIM for Power Electronics and motor control. Armature voltage control is preferred because of high efficiency and good speed regulation for dc motors. The speed...

This paper presents a scheme of designing proportional-derivative (PD) observer for chaotic systems. The proposed design is based on contraction theory approach. For this purpose, co-ordinate transformation of variables are used to avoid derivatives of output in observer. Results are numerically verified...
