This chapter examines the effects of femoral neck geometry and topological structure on elastic properties. A finite element code is used to calculate the full elastic tensor for thirteen human proximal femur specimens. We show that the micro-structure within the human femoral neck and head gives rise to approximate orthotropic elastic symmetry at the whole bone scale. The finite element code c...

progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. both general services administration (gsa) and united states department of d...

Abstract— The purpose of this paper is to give a compact summary of recent results based on the concept of a regular positive-real function. We will list an efficient set of networks which is capable of realising all biquadratics which are realisable by 5-element networks or 6-element networks of seriesparallel type. The structures are simpler than the full BottDuffin synthesis, though there ar...

Bovine adenovirus type 3 (BAdV3) is being used in the development of potential vehicles for gene therapy and vectored vaccine. To that end, a more comprehensive description of BAdV3 biology is essential. In this study, we focused on the role of pIX in BAdV3 virion rescue after full-length BAdV3 genome transfection. Initially, pIX deletion or initiation codon mutation abolished the production of...

A general approach to the dimension reduction of non-linear finite element models of solid dynamics is presented. It is shown how for the Newmark implicit discretization in time the computationally most expensive phase in the equilibrium iteration, namely the solution of the system of linear equations for displacement increments, can be formulated in an approximation basis of much reduced dimen...

A new scheme for implementing a reduced order model for complex meshbased numerical models (e.g. finite element unstructured mesh models), is presented. The matrix and source term vector of the full model are projected onto the reduced bases. The proper orthogonal decomposition (POD) is used to form the reduced bases. The reduced order modelling code is simple to implement even with complex gov...

an analytical nonlinear stress-strain model and a microscopic damage index for confined and unconfined concretes together with a macroscopic damage index for reinforced concrete (rc) structures under cyclic loading are proposed. in order to eliminate the problem of scale effect, an adjustable finite element computer program was generated to simulate rc structures subjected to cyclic loading. by...

the pseudo-elastic behavior of shape memory alloy (sma) truss and cantilever beam are investigated. brinson’s one-dimensional material model, which uses the twinned and detwinned martensite fractions separately as internal variables, is applied in the algorithm to establish the sma stress-strain characteristics. this material model also incorporates different young’s modulus for austenitic and ...

The paper investigates the conditions for full and partial synchronization in systems of coupled chaotic maps that include the presence of a major element, that is, an element that interacts with all the other elements of the system. We consider a system which consists of two globally coupled populations of one-dimensional maps that interact via a major element. The presence of this element can...

A few occurrences of miniature inverted-repeat transposable elements (MITEs) have been reported in species of the genus Drosophila. Here, we describe msechBari, a MITE-like element in Drosophila sechellia. The element is short, approximately 90 bp in length, AT-rich and occurs in association with, or close to, genes, characteristics that are typical for MITEs. The identification was performed i...
