Stacks of longitudinally polarized piezoelectric elements with alternating polarity have long been used to achieve high acoustic outputs, such as in lithotripter transducers. Crystals exhibiting a shear piezoelectric response can also be stacked in this manner, and the alignment of their shear axes is a strong factor in their behavior. For crystals whose piezoelectric response includes both lon...

A new approach to parallel fault simulation for sequential circuits based on Binary Decision Diagrams (BDD) is proposed. The efficiency of BDDs for simulation is well known. However, traditional BDDs are not well-suited for fault simulation. Furthermore, up to now, they have not been used for parallel simulation. In the paper, a new class of BDDs is presented, called Structurally Synthesized BD...

The numerical investigation of drop deformation and breakup under simple shear is a basis for theoretical studies of emulsification and mixing. A three-dimensional Couette flow without gravity is considered; the matrix liquid is bounded at the top and bottom by two parallel horizontal plates and the liquid drop is suspended there. The boundaries move horizontally, and generate a simple shear fl...

In this paper, fault-tolerant feature of TOPAS parallel programming environment for distributed systems is presented. TOPAS automatically analyzes data dependence among tasks and synchronizes data, which reduces the time needed for parallel program developments. TOPAS also provides supports for scheduling, load balancing and fault tolerance. The main topics of this paper is to present the solut...

Symbolic computation is an important area of both Mathematics and Computer Science, with many large computations that would benefit from parallel execution. Symbolic computations are, however, challenging to parallelise as they have complex data and control structures, and both dynamic and highly irregular parallelism. The SymGridPar framework has been developed to address these challenges on s...

This study aims to analytically implement base isolation with soil–structure interaction (SSI) on a sample structure and develop very simple solution add these combined effects into the mass, damping stiffness matrices of structure. A spectrum analysis is also carried out considering base-isolated structures SSI. Dynamic simulations are performed throughout study. In simulations, three shear fr...

The seismicity in the SE Iberian Peninsula is distributed parallel to coast a well-developed strike-slip fracture system known as Eastern Betic Shear Zone (EBSZ). This work focuses on characterization of shallow subsurface structure Algezares-Casas Nuevas Fault, within Carrascoy Fault System EBSZ. borders Guadalentín Depression south, which densely populated area with extensive agricultural act...

This paper discusses Coulomb failure criteria for brittle deformation of intact rock and fault gouge. Data are presented from laboratory experiments designed to identify the critical gouge layer thickness required to effect a transition from the standard Coulomb criterion to a modified failure law (referred to as Coulomb plasticity) appropriate for simple shear of a gouge layer. Experiments wer...
