Motivated by considering the application of a ship carrying either a crane(s), or perhaps fluids in internal tanks, here we model an elastic beam stressed under two separate loads, which we will see brings important dimensionality differences to the single load scenario we studied in [37], and modeled spatiotemporal evolution by principle curves methods. These beam models generally yields a Par...

In this paper, the nonlinear conjugate map is applied based on the conjugate Hasofer-Lind and Rackwitz- Fiessler (CHL-RF) method to evaluate the reliability index using the first order reliability method of the embedded nanocomposite beam, which is made of a polymer reinforced with carbon nanotubes (CNTs). The structure is simulated with the Timoshenko beam model. The Mori-Tanaka model is appli...

We compute the cosmological perturbations generated in the colliding bubble braneworld universe in which bubbles filled with five-dimensional antide Sitter space (AdS5) expanding within a five dimensional de Sitter space (dS5) or Minkowski space (M5) collide to form a (3+1) dimensional local brane on which the cosmology is virtually identical to that of the RandallSundrum model. The perturbatio...

in this paper a novel all-optical logic nand, nor and xor gate based on nonlinear directional coupler theory is demonstrated. we use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. in other words, while a beam with 4 w/μm in power considered as logical one, the output is nand gate and if a beam w...

The aim of the study was to examine the deformation modes and also degradation of an adhesively bonded rectangular cross section beam used in the automotive body structure. The study included: (1) performing new experimental investigations on the three-point bend behavior of a rectangular cross section beam made by adhesive bonding method. (2) developing a finite element (FE) model to predict t...

In the so-called “Two-Beam Acceleration Scheme” the energy of a drive beam is converted to rf power by means of a “Transfer Structure”, which plays the role of power source. In The Transfer Structure the bunched drive beam is decelerated by the electromagnetic field which it induces and builds up by the coherent interaction of successive bunches with the chosen longitudinal mode. The CLIC Trans...

Using a macroparticle model for both synchrotron motion and beta-tron motion, we provide formulae for the beam centroid shift, the tune shifts and the growth rates of the longitudinal and transverse head-tail instabilities. Both single turn and multi-turn eeects are included. The transient amplitudes based on the two-particle model are estimated. We estimate the microwave instability for the mu...

A new approach is developed for finite element modeling of muiti-layer laminated beams. Within the beam element, the laminate is decomposed as muttiple basic layers, such as base beam layers of metal like, soft-core layers of adhesives, and soft coating layers of polymers, and mass and stiffness matrices of these basic layers are assembled together to generate those matrices for the beam elemen...
