Abstract Interfacial surface roughness can result in fluid leakage of seals, and the design seals it is standard to give an upper limit for root-mean-square (rms) amplitude $$h_\text{rms}$$ h rms . However, determined mainly by long-wavelength roughness, which (ne...

We present the rms-intensity diagram for black hole transients. Using observations taken with the Rossi X-ray timing explorer we study the relation between the root mean square (rms) amplitude of the variability and the net count-rate during the 2002, 2004 and 2007 outbursts of the black hole X-ray binary GX 339-4. We find that the rms-flux relation previously observed during the hard state in ...

In this paper, we investigate the effect of using a novel cost, RMS (Root Mean Square) cost, for segment selection for concatenative Text-to-Speech. The RMS cost is affected not only by the total degradation of naturalness but also by the local degradation of naturalness. From the results of experiments comparing this approach with segment selection based on a conventional average cost, it is f...

An important parameter of MIMO channel models is the cluster root-mean-square (rms) directional spread. We introduce a novel method to estimate cluster rms spreads from measurements. We use the SAGE algorithm to extract propagation paths, from which we define clusters in the angular domain, and subsequently estimate the cluster spreads based solely on propagation paths within the clusters. To c...

In this paper we compute the root-mean-square (RMS) gain of a switched linear system when the interval between consecutive switchings is large. The algorithm proposed is based on the fact that a given constant γ provides an upper bound on the RMS gain whenever there is a separation between the stabilizing and the antistabilizing solutions to a set of γ-dependent algebraic Riccati equations. The...

Ictal and interictal single-photon emission CT (SPECT) play an increasingly important role in the surgical evaluation of patients with epilepsy. We present a method of coregistration of MR, SPECT, and CT images to correlate structural data (MR imaging), blood flow changes (SPECT), and location of subdural electrodes (CT) for patients undergoing image-guided surgical treatment of epilepsy. MR-SP...

In this paper, 60 GHz millimeter-wave indoor propagation characteristics are simulated and analyzed using the method of SBR/IM (shooting and bounding ray tracing/image). And the simulated and measured results agree well, so the correctness of the method has been validated. Some propagation parameters are obtained in the simulation, such as the indoor reception power distribution, distribution o...

The combination of genetic algorithm and neural network approach (GANN) has been developed to improve the calculation accuracy of density functional theory. As a demonstration, this combined quantum mechanical calculation and GANN correction approach has been applied to evaluate the optical absorption energies of 150 organic molecules. The neural network approach reduces the root-mean-square (r...

We study numerically the long-time dynamics of a one-dimensional Bose-Einstein condensate expanding in a speckle or impurity disorder potential. Using the mean-field Gross-Pitaevskii equation, we demonstrate subdiffusive spreading of the condensate for long times. We find that interaction-assisted hopping between normal modes leads to this subdiffusion. A possible (partial) reason why the root-...
