Improved Ionospheric Correction for Dual Frequency and Differential GPS Positioning Methods
… in the Jones 3-D ray-tracing program in order to determine the effect of ionospheric horizontal gradient on Global Positioning System (GPS) ray paths. This was used to investigate the accurate mapping of slant to vertical in the presence of horizontal gradient. In differential GPS (DGPS), …

Refining the amplitude of inverse scattering series internal multiple predictions
… space. This space used in combination with higher order terms and 2D adaptive subtraction improves the accuracy of the predicted internal multiples. Second, a non-stationary search limiting parameter is utilized in the time-offset domain allowing for increased flexibility in algorithm …

Finite-strength shock propagation for alternative equations of state
… the inverse square of the Mach number. The zero-order terms correspond to the self-similar results with the higher-order terms being perturbative corrections accounting for nonself-similar effects. Finally, example calculations are made for several different equations of state.

A central composite design to investigate antibody fragment production by Pichia pastoris
… done on each experiment. Mathematical models in terms of these parameters' effects and their interactions were proposed for each of the responses. The significance of each effect and interaction, as well as the goodness-of-fit of mathematical models to data were examined by analysis of variance. …

Using Crustal Thickness Modeling to study Mars' Crustal and Mantle Structures
… contrast, the smaller the crustal thickness. Higher-order terms in the algorithm equation were also tested. Results show that the higher-order terms do not affect the overall crustal thickness by much thus are negligible. In modeling the crustal thickness, a minimum crustal thickness of 5 km …

The elastic stress field produced by a point force in a cubic crystal
… noted that for Cu a contribution of additional terms besides that given by Eshe1by appears in the angular dependence of dilatation for the triple double force but for At the dilatation is in close agreement with Eshe1by's result. The elastic interaction energies of two triple double force …

Application of r-Adaptation Techniques for Discretization Error Improvement in CFD
… error. Truncation error represents the higher order terms in an infinite series which are truncated during the discretization of the continuous governing equations of a model. Discretization error can be reduced through uniform grid refinement but is often impractical for typical …

Electromagnetic response of time-reversal breaking metallic phases in two dimensions
… is broken spontaneously by using the method of higher dimensional bosonization. Mean-field calculations show that the order parameter is two two-component real vectors [Sun and Fradkin 2008]. There are two phases: the beta phase in which the two order parameters are perpendicular and the alpha …

Accurate Prediction of Chiroptical Properties
… basis set superposition errors and requiring higher-order terms in the expansion to provide reasonable accuracy. In addition, we have begun the process of implementing a gauge invariant version of coupled cluster response properties to address the fundamentally unphysical lack of gauge …

Stabilized Finite Element Methods for Feedback Control of Convection Diffusion Equations
… finite element method. We use cubic B-splines in order to keep the higher order terms that occur in GLS formulation. We conduct a careful numerical investigation into the convergence and accuracy of the functional gains computed using stabilization. We also conduct numerical studies of the role …

Large deformation analysis of laminated composite structures by a continuum-based shell element with transverse deformation
… laminated composite plate/shell structures. In order to satisfy the plate/shell surface traction boundary conditions and to have accurate stress description while maintaining the low cost of the analysis, a newly assumed displacement field theory is formulated by adding higher-order terms to the …

New full wave theory for plane wave scattering by a rough dielectric surface - the fictitious current method
… This new theory begins by postulating a zero-order field solution which does not satisfy Maxwell's source-free field equations. The zero-order field, however, is made to satisfy Maxwell's source equations. This is done by introducing a fictitious volume current distribution. Since the original …

Chiral effective field theory beyond the power-counting regime.
