Using the Laplace—Beltrami problem on an implicitly defined surface Γ as a model PDE, we define Lagrange finite element methods of arbitrary degree on polynomial approximations to Γ which likewise are ...

Econometrica publishes original articles in all branches of economics - theoretical and empirical, abstract and applied, providing wide-ranging coverage across the subject area. It promotes studies ...

A landmark discovery on an ancient branch of the River Nile may have solved the mystery of how the pyramids in Egypt were built centuries ago. The now dried-out waterway, which once ran through Giza ...

Real Engineering Challenge: When you drill holes in aircraft wings, pressure vessels, or mechanical components, stress concentrates around these holes at levels 2-3 times higher than the applied load.

Line start permanent magnet (LSPM) motor is noted as an alternative to the induction motor because it offers a very high efficiency and unit power factor. In this paper, the effects of rotor ...

Accruals are transactions incurred that impact a company's net income even though cash hasn't yet changed hands. Accrual accounting is preferred by IFRS and GAAP.

Discounted cash flow (DCF) is a valuation method used to estimate the attractiveness of an investment opportunity. Learn how it is calculated and when to use it.

Abstract: High-temperature superconducting (HTS) twisted stacked-tape conductor-cable in conduit conductors (TSTC-CICC) are critical in superconducting fusion research. The quantification of ac losses ...

The Open FUSION Toolkit (OFT) is a suite of modeling tools, and their underlying finite element framework, for problems in plasma and fusion research and engineering in arbitrary 2D and 3D geometries.

Methods: A ligament-intact three-dimensional finite-element model of a right-sided Denis type II sacral fracture, including ipsilateral superior and inferior pubic rami fractures, was generated.
