Polynomial Spline Collocation Method For Nonlinear Two--Dimensional Weakly Singular Integral Equations

, 2007
INTRODUCTION The solution of a second kind Fredholm integral equation with weakly singular kernel is typically nonsmooth near the boundary of the domain of integration (its derivatives are unbounded, see, for example, [1-3, 5, 7-8, 10-14]). If one wants

An Intensity Measure‐Based Methodology for Ground Motion Orientation in Seismic Structural Assessment

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

Profiling of Dietary Fiber From Pumpkin (Cucurbita moschata) Seed Hulls Pertaining to Monosaccharide Composition, Structural, Thermal, and Functional Properties

Food Chemistry International, EarlyView.
Dietary fiber (soluble/insoluble) was recovered from pumpkin seed hulls using hydrothermal extraction. Process parameters were optimized, and a comprehensive profiling of recovered fiber fractions was performed. ABSTRACT Insoluble (IDF) and soluble dietary fiber (SDF) were recovered from pumpkin seed hulls (PSHs) using hydrothermal treatment ...
