Analysis of Simply Supported Laminated Composite Plate by Semi Analytical and Finite Element Method for Different Orientation Angles

Journal of Mechanical Engineering, 2023
Deflection of simply supported laminated composite plate under transverse load is found out by semi-analytical method (Classical Lamination Theory) and the results are compared with Finite element method using FEA software ANSYS.

Error analysis for full discretizations of quasilinear parabolic problems on evolving surfaces

, 2015
Convergence results are shown for full discretizations of quasilinear parabolic partial differential equations on evolving surfaces. As a semidiscretization in space the evolving surface finite element method is considered, using a regularity result of a

Krylov subspace approximations for the exponential Euler method: error estimates and the harmonic Ritz approximant [PDF]

, 2011
We study Krylov subspace methods for approximating the matrix-function vector product φ(tA)b where φ(z) = [exp(z) - 1]/z. This product arises in the numerical integration of large stiff systems of differential equations by the Exponential Euler Method ...

The Effects of Canning on the In Vitro Solubility of Phosphorus in Pet Food

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Excess phosphate (P) intake through inorganic P (Pi) addition is known to cause various adverse health effects while declaration of use and amount in pet food in the EU is not regulated. Distinction between organic phosphate (oP) from feed ingredients and Pi with standard laboratory methods is impossible.

Distance From Treatment Is Associated With Poorer Admission Status and Worse Outcomes Among Acutely Malnourished Children

Maternal &Child Nutrition, EarlyView.
Abstract Distance from health facilities is an important predictor of treatment seeking and health outcomes. We aimed to describe the relationship between distance from care with admission characteristics and treatment outcomes among children admitted to malnutrition treatment.

Free Vibration Analysis of Arbitrary-Shaped Plates Based on the Improved Rayleigh–Ritz Method

Advances in Civil Engineering, 2019
In this investigation, an improved Rayleigh–Ritz method is put forward to analyze the free vibration characteristics of arbitrary-shaped plates for the traditional Rayleigh–Ritz method which is difficult to solve.

Parallel eigensolvers in plane-wave Density Functional Theory [PDF]

, 2014
We consider the problem of parallelizing electronic structure computations in plane-wave Density Functional Theory. Because of the limited scalability of Fourier transforms, parallelism has to be found at the eigensolver level.

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

New Phytologist, EarlyView.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Differences in mycelial turnover and persistence of wood‐decay fungi at the microscale

New Phytologist, EarlyView.
Summary How long do fungal hyphae persist in the environment? And how does this differ between groups and species of fungi? Despite growing knowledge of fungal contributions to decomposition and soil carbon cycles, surprisingly little is known about the turnover of mycelia: What happens to fungal hyphae over time? And how this impacts different fungi's

Influence of Discretely Introduced Cutouts on the Buckling of Shallow Shells with Double Curvature [PDF]

Journal of Applied and Computational Mechanics
The paper analyzes the influence of cutouts on the buckling of shallow shells with double curvature. Based on the Timoshenko-Reissner hypothesis, a mathematical model is presented that considers transverse shifts, material orthotropy, geometric ...
