We study transient ®nite deformations of a neoHookean beam or plate with piezoelectric (PZT) patches bonded to its upper and lower surfaces. The constitutive relations for the PZTs are taken to be linear in the Green-Lagrange strain tensor but quadratic in the driving voltage. A ®nite element code using 8-noded brick elements has been developed and validated by comparing computed results with e...

In quantitative risk assessment, risk is expressed as a function of the hazard, the elements at risk and the vulnerability. From a natural sciences perspective, vulnerability is defined as the expected degree of loss for an element at risk as a consequence of a certain event. The resulting value is dependent on the impacting process intensity and the susceptibility of the elements at risk, and ...

In this paper we seek refined yet efficient computational models of large overall motion in statics and dynamics. The efficiency is achieved by the proposed model of 8-node brick element with rotational degrees of freedom which allows to separate large displacements and large rotations. The independent rotation field leads to an intrinsic representation of the rotation tensor, ensuring a smooth...

In this paper, we investigate the BSR (Broadcast with Selective Reduction) model of computation for problems related with subsegments (basically, inputs are arrays containing elements and outputs are \some contiguous part" of inputs), namely MSSP (Maximal Sum Subsegment Problem { one and two dimensional version) and LIS (Longest Increasing Sequence). The BSR model of computation introduced by A...

We examine the matrix element of a current with arbitrary number s of four vector indices between one particle states of definite helicity. The conservation of the angular momentum in the brick wall reference frame was used to derive a set of linear relations between the matrix elements. Requiring the helicities of the particles to be conserved asymptotically, we derive a restriction on the spi...

A computer code is developed to accurately simulate the three-dimensional heat transfer during the thermoset fiber placement composite manufacturing process. The code is based on the Lagrangian formulation of the problem. Eight-node brick elements are employed, and the 2 2 2 integration rule is used to numerically evaluate the integrals over an element. The coupled ordinary differential equatio...

This paper presents the residual mechanical properties of concrete made with crushed bricks and clay roof tile aggregates after exposure to high temperatures. One referent mixture and eight mixtures with different percentages of replacement of natural aggregate by crushed bricks and roof tiles are experimentally tested. The properties of the concrete were measured before and after exposure to 2...

background: the aim of this study was to measure137cs levels in soil and brick samples to set the baseline data and an indicator of fallout radioactivity for this part of the world. this study will help to probe, if there is any health threat posed by 137cs exposure to the residents of the area. materials and methods: twenty five samples of soil and 6 samples of bricks were collected from diffe...

We introduce a tiled 3D MIP map representation of global illumination data. The representation is an adaptive, sparse octree with a “brick” at each octree node; each brick consists of 83 voxels with sparse irradiance values. The representation is designed to enable efficient caching. Combined with photon tracing and recent advances in distribution ray tracing of very complex scenes, the result ...

the development activities would impose some risks to environment. these probable risks are different with respect to the nature of the project and vulnerabilities of the environment. the brick kilns factories have considerable potential effects on the environment. so, by assessing the environment and presenting a suitable management these negative potential effects can be decreased to a minimu...
