This work presents a second-order inelastic analysis of steel arches. The analysis of shallow and non-shallow arches with several cross sections and boundary and loads conditions are discussed. The ...

Abstract: It is well known that the Newton-Raphson method is the most popular iterative method for nonlinear finite element problems. The method has a quadratic convergence. Under certain conditions ...

You can use the Phase Plane and Slope Field apps to qualitatively analyze ordinary differential equations (ODEs). Phase Plane app: Analyze two-dimensional autonomous ODE systems. Slope Field app: ...

Standard CoxPH solvers (lifelines, scikit-survival, R survival) load the full cohort into memory before fitting, so on registry-scale data they exhaust RAM long before the computation is hard.

A simple, low cost, and precision frequency meter uses only two pins of a pc parallel port (Figure 1). The TTL-level periodic input signal with frequency f IN connects to the ACK pin of LPT1. This ...

Surface texturing is helpful in decreasing the friction, decreasing the wear, and increasing the fluid film stiffness. This investigation studies the influence of micro-pit arrangement on the behavior ...

It’s well known that the main job of a pulse width modulator’s filter is to limit the maximum peak-to-peak amplitude of the f PWM Hz-induced ripple. It attenuates this to a specified fraction—Frac of ...

Game developers didn’t have it easy in the 1990s. Because they had extremely limited computing power, they had to write their code as efficiently as possible. Consider the first-person shooter Quake ...

Abstract: Combination of initial approximation through a table look-up and Newton-Raphson iteration is an effective way to compute reciprocal, which may replace the division operation. This paper ...

Tensegrity structures are geometric nonlinear systems and statically and kinematically indeterminate structures that require an initial shape-finding procedure to establish a self-equilibrium state.
