We present a denoising technique in the domain of time series data that presumes a model for the uncorrupted underlying signal rather than a model for noise. Specifically, we show how the non-linear reconstruction of the underlying dynamical system by way of time delay embedding yields a new solution for denoising where the underlying dynamics is assumed to be highly non-linear yet low-dimensio...

The spectrum of electron phase space density fluctuations of a plasma is calculated by a novel method that parallels conventional calculations of the partition function in statistical physics. Expressions for the electric field fluctuations and the closely related form factor agree with existing results. The method clears up ambiguous statements about equipartition and provides a new expression...

current literatures on urban parks and green spaces showed that people’s preference for visiting urban parks in various group users is different. people visit parks for various motives and activities, leading to several patterns of park usability. however, the patterns in urban park use in majority of iran cities are not yet known. this study presented the preference for activity in urban parks...

We present a method of adiabatically changing the local phase-space density of an ultracold gas using a combination of magnetic and optical forces. Applying this method, we observe phase-space density increases in a gas of sodium atoms by as much as 50-fold. The transition to Bose-Einstein condensation was crossed reversibly, attaining condensate fractions of up to 30%. Measurements of the cond...

In the present paper, we are contemplating the influences of heterogeneities and pre-stresses on the propagation of Love-type waves in an initially stressed heterogeneous transversely isotropic layer of finite thickness lying over an inhomogeneous half space. The material constants and pre-stress have been taken as space dependent and arbitrary functions of depth in the respective media. To sim...

We propose an extension to Nomarski differential interference contrast microscopy that enables isotropic linear phase imaging. The method combines phase shifting, two directions of shear and Fourier-space integration using a modified spiral phase transform. We simulated the method using a phantom object with spatially varying amplitude and phase. Simulated results show good agreement between th...
