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)
This paper presents an optimal adaptive modulation (AM) algorithm using a cross-layer approach which combines truncated Automatic repeat request (ARQ) protocol and packet combining. Transmissions are performed on WiMAX over multiple-input multiple output (MIMO) Nakagami fading channels. Orthogonal frequency division multiplexing (OFDM) system is used. The(More)
We report a clinical case of a 22-year-old female referred to our institution due to palpitations and preexcitation. Her ECG suggested a right superior paraseptal accessory pathway (AP), which was localised during the electrophysiological study at the superior paraseptal region in close proximity to the His recordings. Reproducible orthodromic reciprocating(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)
