Digital Right Management systems (DRMs) generally handle media data in a compressed and encrypted form. It is often necessary to watermark these media items in the compressed-encrypted domain itself for tamper detection or ownership declaration or copyright management purposes. It is a challenge to watermark these compressed encrypted streams as the compression process would have packed the information of raw media into a low number of bits and encryption would have randomized the compressed bit stream. Attempting to watermark such a randomized bit stream can cause a dramatic degradation of...

Various task scheduling models are in use currently, but the one which we will be focusing on is the ANN (Artificial Neural Network)-based model. This model was set up to estimate the task execution status for resource allotment among the candidates. An ANN-based model makes use of various scheduling algorithms to find the best results possible in terms of quality of service(QoS), total cost, service satisfaction, etc.

Gutta Percha is being used in dentistry, especially in the field of endodontics for a very long time with lot of clinical success. This text book describes the manufacturing of the product, its physical and chemical nature and its various forms, used in root canal treatment. Recent manufacturing modifications have taken this material a step further and has made it a material of choice for endodontists till a better replacement is found in the future. This text book will help dental undergraduates and post graduates understand the material better to work more efficiently with it. This text...
