We present a set of programs and a website designed to facilitate protein structure comparison and protein structure modeling efforts. Our protein structure analysis and comparison services use the LGA (local-global alignment) program to search for regions of local similarity and to evaluate the level of structural similarity between compared protein(More)
To increase data rate of wireless medium with high performance, orthogonal frequency division multiplexing (OFDM) is used. Recently wavelet transform is a possible transform to generate the sub channels in a multicarrier system. Discrete wavelet transform (DWT) is faster than fast Fourier transform (FFT) hence it's replaced by transform technique for OFDM(More)
COOPERATIVE DATA PROTECTION Yupu Zhang Storage systems employ various techniques to protect user data from hardware failures and software defects. These techniques, while effective in their own domains, fail to provide comprehensive protection. In this dissertation, we identify the problem of isolated protection in both local storage systems and cloud(More)
