Phase splitting
It became the purpose of this study to design, build and test an electronic oscillator capable of exciting an electrodeless discharge in hydrogen in which the Doppler shifts would be exhibited in a regular manner.

A new method to test shear wave splitting: improving statistical assessment of splitting parameters
Shear wave splitting has proved to be a very useful technique to probe for seismic anisotropy in the earth’s interior, and measurements of seismic anisotropy are perhaps the best way to constrain the strain history of the lithosphere and asthenosphere. However, existent methods of shear wave …

Blueberry Fruit Development and Splitting
<p>Rain-related splitting of blueberry fruit is a problem facing growers in the southeastern United States and causes an estimated profit loss of up to 20% ($300- $500 per acre). Studies of this phenomenon in other thin-skinned, soft, fleshy fruit showed that no single or set of related …

Splitting rides in transit deserts: Ride-splitting dynamics in Chicago before, during and after the pandemic
… service, also known as “transit deserts”. Ride-splitting was introduced by TNCs as an affordable on-demand mobility option which offers door-to-door service while sharing a trip with another passenger. Due to its affordability, ride-splitting can increase even more the accessibility of …

Splitting schemes for nonlinear parabolic problems
… papers, which all analyse different aspects of splitting schemes when applied to nonlinear parabolic problems. These numerical methods are frequently used when a problem has a natural decomposition into two or more parts, as the computational cost may then be significantly decreased compared to …

Longitudinal Slab Splitting in Composite Girders
Longitudinal slab splitting in composite hot rolled girders and joist girders was investigated. Two different type of framing configurations were studied with two tests conducted per configuration. The framing configurations were designated as either flush-framed or haunched, which describes the …

Shear Wave Splitting Analyses in West Texas
We have analyzed shear wave splitting data from local earthquakes in the Permian Basin in West Texas to understand crustal stress and induced seismicity. The selected events of ML2.0 are recorded by the TexNet and USArray/Transportable Array (TA) stations. SWS parameters, the fast polarization …

Virtual forced splitting in multidimensional access methods
… fanout. Its approach to doing this, by forced splitting, is shared by a collection of other structures, and in 1995 Freeston suggested a novel approach to mitigate the effects of forced splits, by executing them virtually. This approach has not been taken up widely, but we believe it shows a …

Splitting solution scheme for material point method
Material point method (MPM) is a numerical tool which was originally used for modelling large deformations of solid mechanics problems. Due to the particle based spatial discretiza- tion, MPM is naturally capable of handling large mass movements together with topological changes. Further, the …

Two phase flow splitting in piping branches
… are to evaluate the performance of a flow-splitting tripod, discover the factors which most affect the flow distribution; and quantify the effects of geometry, quality and flow rate on the distribution. Knowing all this allows one to predict the distribution for given conditions. An R-22 …

Obstructions to slicing knots and splitting links
… sequence collapses gives a lower bound on the splitting number of the link, the minimum number of times its components must be passed through one another in order to completely separate them. In addition, we build on work of Kronheimer- Mrowka and Hedden-Ni to show that Khovanov homology …

Operator splitting methods for the Navier-Stokes equations
… are representative of the two prevalent splitting philosophies used to split the Navier-Stokes equations. The properties of the algorithms are determined by Fourier analysis of a model problem. It is shown that splittings resulting in Stokes subproblems have desirable dissipative …

Splitting hairs : a sociological approach to educational knowledge
This thesis represents a series of investigations into the sociological study of symbolic forms. It seeks to address the question as to whether, in the informational or knowledge society of late modernity, all symbolic forms are necessarily isomorphic, or whether they will correspond with the new …

Iron-oxide catalyzed silicon photoanode for water splitting
… study of high efficiency photoanodes for water splitting using silicon and iron-oxide. The fundamental limitations of silicon to water splitting applications were overcome by an ultrathin iron-oxide film stack and a pH-adjusted electrochemical environment. It was experimentally demonstrated that …

Statistical Inference for Stochastic Differential Equations using Splitting Schemes
… differential equations (SDEs), focusing on splitting schemes and their applications. <br /> Initially, new numerical properties of splitting schemes, specifically the Lie-Trotter and Strang schemes, are established, enabling more accurate and robust parameter estimation under less …

High Order Fluctuation Splitting Schemes for Hyperbolic Conservation Laws
… new form of higher than second order fluctuation splitting discretisation for the solution of steady conservation laws on unstructured meshes. This is an alternative approach to the two existing higher than second order fluctuation splitting schemes, which use submesh reconstruction (developed by …

Holographic Spectrum-Splitting Design for Micro-Concentrating Photovoltaic Applications
… low cost. During the past few years the spectrum-splitting technology has been recognized as an important method to improve the overall power conversion efficiency and energy yield of solar photovoltaic systems. It can reach high efficiency by spatially assigning photons to PV cells with different …
