We present a spectral approach to design approximation algorithms for network problems. observe that the underlying mathematical questions are rounding problems, which were studied in sparsification and discrepancy theory. extend these results incorporate additional non-negative linear constraints, show they can be used significantly scope of problems solved. Our algorithm is an iterative rando...

because the underlying physiology of pathological tremor in a parkinson's patient is not well understood, the existing physical and drug therapies have not been successful in tremor treatment. different mathematical modeling of such vibration has been introduced to investigate the problem and reduce the existing vibration. most of the models have represented the induced vibration as a sinusoida...
