Di usion in poro - plastic media

A model is developed for the ow of a slightly compressible uid through a saturated inelastic porous medium. The initial-boundary-value problem is a system that consists of the di usion equation for the uid coupled to the momentum equation for the porous solid together with a constitutive law which includes a possibly hysteretic relation of elasto-visco-plastic type. The variational form of this...

Reaction-Di usion Fronts in Periodically Layered Media

We compute the e ective wave front speeds of reaction-di usion equations in periodically layered media with coe cents that have small amplitude oscillations around a uniform mean state. We compare them with the corresponding wave front speeds in the uniform state. We analyze a one dimensional model where wave propagation is along the layering direction of the medium and a two dimensional shear ...

Clog4c1.1 IBM

Different modulation schemes supporting multiple data rates in a Direct Sequence Code Division Multiple Access (DS/CDMA) system are studied. Both AWGN and multipath Rayleigh fading channels are considered. It is shown that the multi processing-gain scheme and the multi-channel scheme have almost the same performance. However, the multi-channel scheme may have some advantages due to near-far res...

Knowledge Sharing and Collaboration through Social Media - the Case of Ibm

O Computador Quântico da IBM e o IBM Quantum Experience

O anúncio de um computador quântico que pode ser acessado de forma remota por qualquer pessoa a partir de seu laptop é um acontecimento de grande importância para os cientistas da computação quântica. Neste trabalho nós apresentamos o computador quântico da International Business Machines (IBM) e sua plataforma IBM Quantum Experience (IBM-QE) como uma proposta didática em estudos de computação ...
