—A logger in the cloud capable of keeping a secure, time-synchronized and tamper-evident log of medical device and patient information allows efficient forensic analysis in cases of adverse events or attacks on interoperable medical devices. A secure logger as such must meet requirements of confidentiality and integrity of message logs and provide… (More)
For the numerical evaluation of multiple integrals of analytic functions ofn complex variables, a (4 n +1)-point degree five non-product rule has been constructed discarding certain points from the set of 5 n nodes needed in the product layout based on the five point degree five rule due to Birkhoff and Young. An asymptotic error estimate for the casen=2… (More)
A nine-point degree five rule for the numerical approximation of double integrals of analytic functions of complex variables and its error bound have been derived. Es wird eine 9punktige Formel vom Grad 5 zur numerischen Approximation von Doppelintegralen komplexer Variablen samt Fehlerschranke hergeleitet.
A numerical technique based on the Cauchy integral formula of complex analysis has been employed for evaluating the integrals and derivatives of fractional orders of an analytic function. The method of subtraction of singularity has been used to evaluate the contour integrals for a desired degree of accuracy.
Seven point and eight pointquadrature rules have been generated for the numerical evaluation of two dimensional integral of an analytic function of two complex variables.The truncation error associated with the rules have been analysed and it has been established that both the rules have degrees of precision five.Some examples have been considered for the… (More)
