The quality of satellite images propagating through the atmosphere is affected by phenomena such as scattering and absorption of light, and turbulence, which degrade the image by blurring it and reducing its contrast. The atmospheric Wiener filter, which corrects for turbulence blur, aerosol blur, and path radiance simultaneously, is implemented in the digital restoration of Landsat Thematic Ma...

In this paper we assessed the possibility of using the pulse rate (PR) extracted from the photoplethysmographic signal for turbulence detection as an alternative to the heart rate (HR). The study is based on analysis of the rhythm changes observed during 4131 ventricular premature beats of 27 subjects. Classical features for turbulence analysis, turbulence onset and turbulence slope were estima...

We present numerical simulations of electron magnetohydrodynamic (EMHD) and electron reduced MHD (ERMHD) turbulence. Comparing scaling relations, we find that both EMHD and ERMHD turbulence show similar spectra and anisotropy. We develop new techniques to study anisotropy of EMHD turbulence. Our detailed study of anisotropy of EMHD turbulence supports our earlier result of k‖ ∝ k ⊥ scaling, whe...

The weak version of universality in turbulence refers to the independence of the scaling exponents of the nth order structure functions from the statistics of the forcing. The strong version includes universality of the coefficients of the structure functions in the isotropic sector, once normalized by the mean energy flux. We demonstrate that shell models of turbulence exhibit strong universal...

In this study, modeling of a fuel jet which has been injected by high pressure into a low-pressure tank are investigated. Due to the initial conditions and the geometry of this case and similar cases (like CNG injectors in internal combustion engines (ICE)), the barrel shocks and Mach disk are observed. Hence a turbulence and transient flow will be expected with lots of shocks and waves. Accord...

The interaction of a shock with a cloud has been extensively studied in the literature, where the effects of magnetic fields, radiative cooling and thermal conduction have been considered. In many cases, the formation of fully developed turbulence has been prevented by the artificial viscosity inherent in hydrodynamical simulations. This problem is particularly severe in some recent simulations...

Title of Document: TOWARDS AN AUTONOMOUS ALGAL TURF SCRUBBER: DEVELOPMENT OF AN ECOLOGICALLY-ENGINEERED TECHNOECOSYSTEM David M. Blersch, Ph.D., 2010 Directed By: Associate Professor Patrick C. Kangas, Department of Environmental Science and Technology The development of an autonomous and internally-controlled technoecological hybrid is explored. The technoecosystem is based on an algal turf sc...

Environmental turbulence is a well-studied contingency of relationships involving firm strategy, structure, and performance. However, it invariably regarded as present condition indeterminate duration. Indeed, some industries are turbulent by their nature with little regard for past, present, or future. What environmental which high in level but short duration? An empirical study conducted the ...
