Ordering of Curving Interfaces
… This thesis examines how materials can order on curving interfaces, resulting in shape changes and pattern formation. Many phenomena that are well-studied in flat space display new behavior when lifted onto a deformable surface: liquid crystals buckle membranes into peaked shapes, diffusing …

Yield curving modelling and estimation
The remainder of this paper is organized as follows. As a first step, we discuss the most relevant interest rate models mentioned in the literature. We then pass onto discussing the most relevant estimation methods found in the literature and choose two of them to test empirically. Finally we draw …

Higher order mesh curving using geometry curvature extrapolation
A higher order mesh curving method is developed which uses information from the geometry to determine the appropriate curvature of edges in the interior of the mesh. Edges are represented using four point Bézier curves to determine the positions of higher order edge points. Higher order face and …

Flow-Through Electroporation in Asymmetric Curving Microfluidic Channels
… can be conducted employing tapered asymmetric curving channels. The size variation in the channel's cross-sectional area makes it possible to produce electric pulses of various parameters by using a dc power supply. We successfully delivered Enhanced Green Fluorescent Protein, EGFP, plasmid DNA …

Collapse analysis of unreinforced masonry domes and curving walls
… The second structural form to be analyzed is the curving masonry wall. In an effort to better understand the origins and perceived benefits of curving masonry walls, their stability is measured relative to the amount of curvature in the wall. The critical value of constant horizontal acceleration …

The Effects of Curving Large, High-Resolution Displays on User Performance
… less user frustration. Findings also reveal that curving large displays improves performance time as users interacted with less strenuous physical navigation on the curved conditions. A second study sought to understand why curving the display, effectively bringing all pixels into visible range, …

Investigation of the finite element method for computing wheel/rail contact forces in steady curving
… of rail vehicle steady-state and dynamic curving has increased substantially in the last few years. Contemporary curving models include such nonlinear effects as two-point contact, creep force saturation, and rail flexibility. The usual approximation concerning the contact geometry is that …

NUCARS Modeling of a Freight Locomotive with Steerable Trucks
… of the impact on tangent track stability and curving performance of varying suspension parameters. It is found that the presence of damping in the system improves hunting stability, while increasing wheel conicity is harmful to stability and varying the flexicoiling stiffness has little …

A comparative study of modified passenger railway vehicle trucks
… elements to provide good dynamic stability. The curving performance of such a vehicle is poor because of wheelset misalignment in curves resulting in increased wheel and rail wear. This increases the maintenance cost. The wheelset misalignment also leads to increased lateral forces which raises …

Fault tolerant strategy for actively controlled railway wheelset
… that this design conflict between stability and curving performance can be solved by applying active control instead of conventional passive components, resulting in the reduction of the wear of the wheels and track by minimising the track shifting forces. In the active approach, the use of …

FtsZ Protofilament Curvature is the Opposite of Tubulin Rings
… of FtsZ, which would have resulted in pfs curving toward the interior of a disassembling MT. Evolution not only eliminated this undesirable curvature, but managed to reverse direction to produce the outward curving rings, which is useful for pulling chromosomes.</p>

Determination of Optimal Stable Channel Profiles
… is limited in that its continuously curving boundary does not allow for sediment transport, which is an essential feature of natural rivers and streams. That model has thus been modified to predict the shape and stress distribution of an optimal stable channel; a channel with a …

… THESE PHENOMENA ARE: DYNAMIC BRANCHING, DYNAMIC CURVING, DYNAMIC KINKING AND CRACK ARREST. A SERIES OF EXPERIMENTS PROVES THAT THE EXISTING "YOTTE MODE" FOR APPLYING MACROSCOPIC FRACTURE CRITERIA FAILS TO GIVE CORRECT RESULTS IN THE CASE OF MOVING CRACKS. A NEW MODE FOR APPLYING THESE CRITERIA IS …

Experimental investigation of the flow field during combustion in narrow circular ducts
… flow was essentially one-dimensional with little curving of the flow tube only near the flame front. Entropy generation from vorticity was negligible when compared with the entropy produced from combustion of methane in oxygen, as it was determined through an application of Crocco’s theorem. This …
