International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 6, Page 2806-2822, 25 April 2026.ABSTRACT Design optimization for automatically generating optimal design results is a promising technique for enhancing the efficiency of design processes and outcomes. However, its development for soil nail reinforced slopes is limited since the traditional slope stability analysis using the limit equilibrium method (LEM) becomes relatively time ...

Numerical cubature from Archimedes' hat-box theorem
, 2004 Archimedes' hat-box theorem states that uniform measure on a sphere projects to uniform measure on an interval. This fact can be used to derive Simpson's rule.

A New Parametric Accelerated Failure Time Model for Semi‐Competing Risks Data
Statistics in Medicine, Volume 45, Issue 8-9, April 2026.ABSTRACT In cohort studies, the occurrence of a specific disease is often of main interest. For proper modeling, death as a competing risk should be accounted for. Especially, the “semi‐competing” character of the data has to be acknowledged: Disease occurrence (the non‐terminal event) can be observed before death (the terminal event), but not vice ...

, 2015 We describe a method for calculating the roots of special functions satisfying second order linear ordinary differential equations. It exploits the recent observation that the solutions of a large class of such equations can be represented via ...

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract A Saturn Electrostatic Discharge or SED is an intense electromagnetic impulse induced by Saturn lightning, which escapes into space through the magnetoplasma of the ionosphere. Since previous SED polarizations from Voyager data are inconclusive, this polarization study is the first which properly considers the characteristics of the Voyager ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.Abstract Point sources are often major contributors of greenhouse gas and air pollutant emissions in urban areas. Dense air monitoring networks provide a unique avenue for studying point source emissions over long time periods. Here, we use the Berkeley Environmental Air‐quality and CO2 Network (BEACO2N) to study CO2 and air pollutant emissions from an

A Gaussian quadrature rule for oscillatory integrals on a bounded interval
, 2012 We investigate a Gaussian quadrature rule and the corresponding orthogonal polynomials for the oscillatory weight function exp{i ω x} on the interval [-1,1]. We show that such a rule attains high asymptotic order, in the sense that the quadrature error quickly decreases as a function of the frequency ω. However, accuracy is maintained for all values of

Numerical Integration in S-PLUS or R: A Survey [PDF]
This paper reviews current quadrature methods for approximate calculation of integrals within S-Plus or R. Starting with the general framework, Gaussian quadrature will be discussed first, followed by adaptive rules and Monte Carlo methods.
