We address an argument by Floridi (2009, 2011), to the effect that digital and analogue are not features of reality, only of modes of presentation of reality. One can therefore have an informational ontology, like Floridi’s Informational Structural Realism, without commitment to a supposedly digital or analogue world. After introducing the topic in Section 1, in Section 2 we explain what the pr...

Investigation of high amplitude pressure oscillations generated by boundary driving in shaped resonators has been carried out both theoretically and experimentally. In the theoretical modeling, the acoustic resonance in an axisymmetric resonator is studied by the Galerkin method. The resonator is exponentially expanded and the boundary driving is provided by a piston at one end. The pressure wa...

This article presents a new approach based on artificial neural networks (ANNs) to calculate the characteristic parameters of elliptic and circular-shaped microshield lines. Six learning algorithms, bayesian regularization (BR), Levenberg-Marquardt (LM), quasiNewton (QN), scaled conjugate gradient (SCG), resilient propagation (RP), and conjugate gradient of Fletcher-Reeves (CGF), are used to tr...

The various perturbing structures for generation of circular polarization (CP) in a hexagonal shaped microstrip antenna (HMSA) with patch side length of 20 mm is used to resonate in the Mobile Satellite Service (MSS) band at a centre frequency of 2 GHz. The hexagonal geometry to achieve CP is perturbed in four different ways: first with a rectangular slot at centre, second with two narrow slits...

We report the observation of steady-state photorefractive vortex-screening solitons. As a singly charged circular vortex nested on a broad beam propagates through a biased strontium barium niobate crystal, it self-traps in both transverse dimensions despite the inherent anisotropy of the photorefractive nonlinearity. When the vortex beam is a doughnut-shaped narrow beam, it breaks up into two e...

in recent years, the hydroforming due to reduction in weight and increase in strength of automotive parts has attracted attention of the automotive industry. thus, the knowledge of the process to produce parts with desired quality and accuracy has been growing. one of the effective methods in improving the formability in the hydroforming is known as pulsating hydroforming. however, the reason o...

The writings of Wassily Kandinsky and Paul Klee, Bauhaus theorists and pioneers of nonrepresentational art, are the framework for a discussion of contemporary issues in computational design. Kandinsky and Klee wrote of the many misguided dualisms in the art theory and pedagogy of their time. They sought to reconcile the seemingly mutually exclusive issues associated with abstraction in art. Som...

Dear Editor We read the article by Bagheri et al with great interest (1). We found the study interesting and comprehensive as four groups of patients, including operative and nonoperative in either pure dislocation or fracture dislocation, were compared in terms of Mayo wrist score, Grip strength, range of motion and radiographic parameters. It seems that the results were comparable to studies ...
