We report the efficient design of pseudo-random pattern generator (PRPG) with linear time complexity. The PRPG is developed around the regular structure of nonlinear cellular automata (CA). The application of proposed PRPG is demonstrated in designing on-chip test pattern generator (TPG) for VLSI circuits. The quality of the TPG is as good as that designed(More)
In this work, we have studied the observational constraints on the Cardassian Model for the dark energy. We have compared the model with existing Supernova data. The dependence of the location of the Cosmic Microwave Background Radiation (CMBR) peaks on the parameters of the model have also been studied. We find, in particular that observational data(More)
A new cavity perturbation technique is presented for microwave measurement of dielectric constant, which uses a modified cylindrical reentrant cavity. Though suitable for only low dielectric constants, the method has the advantages, (a) sample area does not appear in the calculations, (b) only the ratio of frequency shifts due to two samples of same area(More)
