In this paper we define the rate distortion functions for the memoryless broadcast channels when side information about the source is provided at both the encoder and the decoder. Basic equations and the Variational equations are obtained under two different situations, the most general situation being the case of fidelity criterion acting along the main channel only whereas in the second situa...

With the advancement of technology, data converters are widely used in modern communication and digital signal processing. ADCs are basic building blocks in many applications including storage systems, optical communication, radar communication, instrumentation and high-speed serial data links[1]. Different categories of ADC architectures are available based on their speed, resolution and power...

Lossless coding will become the latest extension of the MPEG-4 audio standard. In response to a call for proposals, many companies have submitted lossless audio codecs for evaluation. The codec of the Technical University of Berlin was chosen as reference model for MPEG-4 Audio Lossless Coding, attaining working draft status in July 2003. The encoder is based on linear prediction, which enables...

In the domain of Bio medical Natural Language Processing (Bio-NLP), the information extraction and context sentiment identification are treated as emerging tasks. Several linguistic features like negation , uni-gram, bi-gram, Part-of-Speech (POS) have been used to extract the medical concepts and their sense-based context level information. Thus, in the present attempt, a hybrid approach which ...

nowadays, many antibiotics are being used to control infectious diseases. inappropriate use of antibiotics leads to emergence of resistant bacteria and problems such as a prolonged course of treatment. medicinal plants and their derivatives, as a good source of treatment, are effective against drug resistance. in this study we have evaluated the antimicrobial activity of herbal essential oils o...

In this paper we present the design of a car test bed. The main characteristic of our test bed is the steering which is Non-Holonomic to resemble the normal car steering. This test bed is a rear wheel drive with frontal steering by servo motor. The control brain consists of RoBoard II and Arduino Micro controller. We used multiple sensors (Ultrasonic range finder, 6 DOF Accelerometer, Wheel enc...

Neural machine translation has shown very promising results lately. Most NMT models follow the encoder-decoder framework. To make encoder-decoder models more flexible, attention mechanism was introduced to machine translation and also other tasks like speech recognition and image captioning. We observe that the quality of translation by attention-based encoder-decoder can be significantly damag...
