This project studies and identifies the PSK-based digital modulation scheme (BPSK, QPSK or GMSK) that gives the best BER performance in a multipath fading environment using computer simulation (MATLAB). Each PSK-based digital modulation are modeled and simulated under different channel conditions. Subsequently, a comparison study is carried out to obtain… (More)
Of considerable interest in recent years has been the problem of exchanging correlated data with minimum communication. We thus consider the problem of exchanging two similar strings held by different hosts. Our approach involves transforming a string into a multi-set of substrings that are reconciled efficiently using known multi-set reconciliation… (More)
This paper a survey of artificial neural network on various welding technology and also discusses the result based on analysis. The role of optimization techniques in concerned domain with experimental analysis is explained. Refer ences-Parikshik dutta, Dilip Kumar pratihar do modelling of TIF welding process using conventional regression analysis and… (More)
It has recently been possible to synthesize ordered assemblies composed of magnetic superatomic clusters Ni9Te6(PEt3)8 separated by C60 and study their magnetic behavior. We have carried out theoretical studies on model systems consisting of magnetic superatoms separated by non-magnetic species to examine the evolution in magnetic response as the nature of… (More)
We report a rare case of giant ossifying chondroma of skull arising from temporoparietal region in a 14-year-old female, which was successfully excised. While reviewing world literature few cases of extracranial chondromas arising from the skull base were found.
We consider the problem of exchanging two similar strings held by different hosts with a minimum amount of communication. We reduce the problem of string reconciliation to a problem of multi-set reconciliation, for which nearly optimal solutions exist. Our approach involves transforming a string into a multi-set of substrings, which are reconciled… (More)
