In the paper written by Cavaliere, Janoska, Yogev, Piran, Keinan, Seeman [4] the authors propose a theoretical model (i.e. not tested in laboratory) of implementation of the push-down automaton built on DNA. The idea was inspired by two papers: the first one by Rothemund [7] who proposed a simulation of the Turing machine the basic theoretical model of computation and the second one by Benenson...

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...

The base isolation systems are among the passive control devices that have been used over the last three decades to limit the seismic-induced response of structures. In this regard, the Uniform Building Code provisions (UBC) has incorporated a special section for the seismic design of base isolated structures since its 1991 edition. Due to the importance of the behavior of these structures unde...

1. Abstract In the real world, structural systems may show nonlinear dynamic behavior. Linear static response structural optimization has been developed quite well by using linear static response analysis. Finite element analysis regarding the nonlinearities or dynamic effects has also been developed very well. However, conventional optimization methods considering the nonlinearities or dynamic...

In this study, a hybrid method is proposed to investigate the nonlinear vibrations of pre- and post-buckled rectangular plates for the first time. This is an answer to an existing need to develope a fast and precise numerical model which can handle the nonlinear vibrations of buckled plates under different boundary conditions and plate shapes. The method uses the differential quadrature element...

Arch dams are generally built in cantilvever monoliths. Vertical contraction joints between monoliths control the stresses due to concrete shrinkage and temperature variations. Past studies in earthquake safety evaluation of the system often show the tensile fracture and local nonlinear deformation of joints. In this paper, some nonlinear joint element constitutive models are presented to exami...

The nominal linear subsystem state-space model having nonlinear couplings are used in this work. The quadratic dissipativity constraint approach, previously introduced and developed for the model predictive control of interconnected systems, is deployed herein with a static state-feedback strategy. We re-use the derivation for a quadratic bound on the nonlinear coupling in a newly derived stabi...

Direct-carrier modulation is an attractive technique for low-cost high-performance radar transceivers. In this paper, it is shown that, when the technique is applied to a generic homodyne radar architecture, the signaling waveform can be software adapted without requiring any hardware modifications. The key circuit in this novel software radar is a -band monolithic – vector modulator employing ...
