A Few More Cyclic Steiner 2-Designs
In this paper, we prove the existence of a cyclic (v, 4, 1)-BIBD for v = 12t + 4, 3 t 50 using computer programs, which are useful in recursive constructions for cyclic designs....

Adaptive Wavelet-based-CMAC Network Predictor Design for Lossless Image Coding
— In this paper, we propose a novel wavelet-based-CMAC (WCMAC) network for predictive image coding. The Gaussian functions of traditional CMAC are replaced by wavelet functions. ...

Intermediate Performance of Rateless Codes
Abstract-- Fountain codes are designed so that all input symbols can be recovered from a slightly larger number of coded symbols, with high probability using an iterative decoder. ...
