Linear ion trap frequency standards are among the most stable continuously operating frequency references and clocks. Depending on the application, they have been operated with a variety of local oscillators (LOs), including quartz ultrastable oscillators, hydrogen-masers, and cryogenic sapphire oscillators. The short-, intermediate-, and long-term stability of the frequency output is a complicated...
The key challenges in the area of public health informatics are, the identification of relevant health data sets, its representation and meaningful use of the information for decision making. To make effective use of data represented in Public Health Records, the data needs to be ‘seamlessly’ shared or be interoperable among health care providers. It is believed that adoption of health care standards...
Video coding standards: H.264/AVC, DIRAC, AVS China and VC-1 are presented. These are the latest standards and are adopted by ITU-T/ISO-IEC, BBC, China standards organization and SMPTE respectively. Besides presenting these standards, research potential and as well projects (both at UG and grad levels) are emphasized. These are available by accessing the database for research and projects in [18]...
Macroblock mode decision is the most expensive process in terms of computational power required. In any video codec motion estimation along with the macroblock mode decision consumes approximately 80% of the encoding time, resulting in encoding maximum of only 2 frames per second. This makes it almost impossible to implement a video codec without using specialized hardware, which causes problems like...
