this study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. starch-based sbr1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer (plastograph brabender).the content in starch was varied from 0 to 50 phr. the effect of starch content on the rheological behavior was evaluated through...

Hydrologic response in natural catchments is controlled by a set of complex interactions between storm properties, basin characteristics and antecedent wetness conditions. This study investigates the transient runoff response to spatially-uniform storms of varying properties using a distributed model of the coupled surface-subsurface sys5 tem, which treats heterogeneities in topography, soils a...

We present a technique to measure the velocity and flow profiles of a nanofluid in a microfluidic channel. Importantly, we extract the flow velocity from a series of standard brightfield images without employing particle tracking or laser-enhanced methods. Our analysis retrieves the flow information from the image structure function of sub-diffraction limited nanoparticles in suspension. We are...

Swath bathymetry system surveys with wide swath, high location resolution, and is used to detect sea bottom terrain. But the object resolution detected decreases as the depth increasing, its data processing with high mistake, used rarely in sea floor object survey.So GeoSwath, a multibeam sonar does. Although it covers an angular range of -120°to 120 °from the vertical direction, providing high...

Introduction: In-vivo MR imaging on humans and animals is often affected by flow and motion of nuclear spins causing blurring and ghosting artifacts [1]. If these moving spins are not of direct investigational interest their effects need to be suppressed or compensated efficiently. For this purpose a variety of techniques has been developed, like preparation modules with saturation pulses, trig...

Sedimentary units generally present anisotropy in their hydraulic properties, with higher hydraulic conductivity along bedding planes, rather than perpendicular to them. This common property leads to a modeling challenge if the sedimentary structure is folded. In this paper, we show that the gradient of the geological potential used by implicit geological modeling techniques can be used to comp...

Two-dimensional free-surface flow over a spatially periodic channel bed topography is examined using a steady periodically forced Korteweg–de Vries equation. The existence of new forced solitary-type waves with periodic tails is demonstrated using recently developed non-autonomous dynamical-systems theory. Bound states with two or more co-existing solitary waves are also identified. The solutio...

In this paper, we have studied the diffusive predator-prey model with Monod-Haldane functional response. The stability of the positive equilibrium and the existence of Hopf bifurcation are investigated by analyzing the distribution of eigenvalues without diffusion. We also study the spatially homogeneous and non-homogeneous periodic solutions through all parameters of the system which are spati...

The physically-based distributed hydrological models play an important role in watershed hydrology. Physical simulation of flow routing depends largely on the field distribution of flow velocity.Terrain analysis studies have previously focused more on the delineation of geomorphologic structures rather than the description of hydraulic factors. As affected by multiple uncertain factors includin...
