This study presents the continuous element formulation for analyzing the dynamic behavior of ring-stiffened cylindrical shells made of FGM material. Based on the solutions of the shell differential equations, the dynamic stiffness matrix is calculated. A procedure to assembly cylindrical and annular shells is introduced in order to compute the natural vibrational frequencies of FGM ring-stiffened cylindrical shells.

The paper "Dynamic analysis of stiffened functionally graded composite plates reinforced by carbon nanotubes under blast loading" presents a study of the geometrical nonlinear dynamic of stiffened functionally graded composite plates reinforced by carbon nanotubes (SFG-CNTRC) subjected to blast loading. The governing equations of the system are obtained using the Mindlin plate theory and von Karman geometric nonlinearity.

This research presents Dynamic Stiffness formulations for studying dynamic behavior of composite inner/outer ring-stiffened cylindrical shells. The continuous elements investigated in this paper are cylindrical and ring elements. Base on dynamic stiffness matrix of the above elements, an assembling procedure is proposed to solve the problem of complex composite inner/outer ring-stiffened cylindrical shells.

Ebook "Physical oceanography: A mathematical introduction with matlab®" is about the interplay between applied mathematics and the field of geophysical fluid dynamics. Its primary goals are to demonstrate how one uses the basic tenets of multivariate calculus to derive the governing equations of fluid dynamics in a rotating frame, and how one uses methods from linear algebra and partial differential equations to solve some of the basic initial-boundary value problems that have become the hallmark of physical oceanography.

MDS (maximum distance separable) matrices are ones that come from MDS codes that have been studied for a long time in error correcting code theory and have many applications in block ciphers. To improve the security of block ciphers, dynamic block ciphers can be created. Using MDS matrix transformations is a method used to make block ciphers dynamic.

This paper presents the dynamic model and singularity-free simulation of electromechanical systems including closed loop multibody systems, massless gear transmission and electric motors. The dynamic model of these systems is established in matrix form and written in a Differential-Algebraic Equations form by applying the Lagrangian equation with multipliers and substructure method.

In this paper, the problem of finite-region stability is studied for a class of two-dimensional (2-D) singular systems described by Roesser model with directional delays. Based on the regularity, the underlying singular 2-D systems are first decomposed into fast- and slow-subsystems corresponding to dynamics and algebraic parts.

Incorporation of therapeutic proteins in a matrix of sugar glass is known to enhance protein stability, yet protection is often lost when exposed to high relative humidity (RH). We hypothesized that especially in these conditions the use of binary glasses of a polysaccharide and disaccharide might yield advantages for protein stability.

The cell surface and extracellular matrix polysaccharide, heparan sulfate (HS) conveys chemical information to control crucial biological processes. HS chains are synthesized in a non-template driven process mainly in the Golgi apparatus, involving a large number of enzymes capable of subtly modifying its substitution pattern, hence, its interactions and biological effects.
