Analytical Rate-Distortion-Complexity Modeling of Wavelet-Based Video Coders
Analytical modeling of the performance of video coders is essential in a variety of applications, such as power-constrained processing, complexity-driven video streaming, etc., whe...

Quantization Effects in Low-Density Parity-Check Decoders
−A class of combinatorial structures, called absorbing sets, strongly influences the performance of low-density paritycheck (LDPC) decoders. In particular, the quantization schem...

On the weight of universal insertion grammars
We study the computational power of pure insertion grammars. We show that pure insertion grammars of weight 3 can characterize all recursively enumerable languages. This is achiev...

On the Round Security of Symmetric-Key Cryptographic Primitives
We put forward a new model for understanding the security of symmetric-key primitives, such as block ciphers. The model captures the fact that many such primitives often consist of...
