Heterogeneous digital stiffness programming

چکیده

A heterogeneous design of mechanical metamaterial enables digital stiffness programmability. The prototype is composed an elastomer matrix containing diamond-shaped cavities that are selectively confined along their diagonals by semi-rigid plastic beam inserts. Unit-cell perturbations caused insert placement or removal reshape the global constitutive relation, whose lower and upper bounds correspond to configurations with all holes empty inserts in place, respectively, due a gap between moduli. Bidirectional operation accomplished varying orientation inserts, longitudinal increasing macroscopic compression transverse tension. Arranged representations such local states form explicit encoding patterns, allowing both statical situ systematic programming minimal mass changes. These properties establish new paradigm for actively tuning vibration isolation systems response changes base structure’s resonances.

Programming Verifiable Heterogeneous Agent Systems

Our overall aim is to provide a verification framework for practical multi-agent systems. To achieve practicality, we must be able to describe and implement heterogeneous multi-agent systems. To achieve verifiability, we must define semantics appropriately for use in formal verification. Thus, in this paper, we tackle the problem of implementing heterogeneous multi-agent systems in a semantical...

Programming Heterogeneous MPSoCs using MAPS

Programming heterogeneous MPSoCs (Multi-Processor Systems on Chip) is a grand challenge for SoC providers and users today. The HW integration level of commercial MPSoC platforms increases at a fast pace. However, lacking tools to support MPSoC programming results in a much slower pace of SW productivity, which hampers deploying MPSoCs significantly. In this paper, we introduce the MAPS (MPSoC A...

Exploiting heterogeneous parallelism with the Heterogeneous Programming Library

While recognition of the advantages of heterogeneous computing is steadily growing, the issues of programmability and portability hinder its exploitation. The introduction of the OpenCL standard was a major step forward in that it provides code portability, but its interface is even more complex than that of other approaches. In this paper we present the Heterogeneous Programming Library (HPL),...

Non-monotonic dependence of the friction coefficient on heterogeneous stiffness

The complexity of the frictional dynamics at the microscopic scale makes difficult to identify all of its controlling parameters. Indeed, experiments on sheared elastic bodies have shown that the static friction coefficient depends on loading conditions, the real area of contact along the interfaces and the confining pressure. Here we show, by means of numerical simulations of a 2D Burridge-Kno...
