We study the computation of the static quark potential under decimations in the Monte Carlo Renormalization Group (MCRG). Employing a multi-representation plaquette action, we find that fine-tuning the decimation prescription so that the MCRG equilibrium self-consistency condition is satisfied produces dramatic improvement at large distances. In particular, lattice coarsening (change of effecti...

The objective of this lecture is to review the basic building blocks of lumped parameter rotational mechanical systems and to build the foundations that will enable you to model more complex dynamic systems consisting of translation and rotational elements. Corresponding to the translational elements mass, spring and damper, are the rotational inertia, rotational spring and rotational damper, r...

In this paper, we first introduce the definition of rotational sets for cellular automata ∞ using Misiurewicz’s rotational sets. After that, we define rotational entropy functions for cellular automata ∞ from Bowen’s definiton of rotational entropy. Finally, we compare rotational entropy function with topologic entropy function for cellular automata ∞.

In this article, turbulent flow heat transfer in the air gap between rotor and stator of a generator under nonhomogeneous heat flux is studied experimentally. The rotor consists of four symmetrical triangular grooves. The stator surface is smooth and does not include any grooves. The relative heat flux between the rotor and the stator is 1 to 3. Temperature and heat flux are measured locally at...

Magnetic abrasive finishing (MAF) is a micromachining process that uses magnetic field and magnetic abrasive particles to conduct the mechanism of material removal in micro-nanometer scales. In this paper, by an experimental method and statistical analysis, the effects of parameters like working gap, work-piece rotational speed and material removal mechanism (injection of abrasive slurry of Al<...

The acute results of repeated interventions for patients with in-stent restenosis (ISR) are largely satisfactory, although some patients may still have recurrences.1,2 In this anatomic scenario, lack of initial angiographic success is exceedingly rare.1,2 We report a patient with “undilatable” ISR that eventually required rotational atherectomy to achieve procedural success. Optical coherence t...

OBJECTIVE The goal of this study was to assess effects of translation (horizontal displacement) and angulation (transducer tilting) on 3-dimensional (3D) echocardiographic volumes of both balloons and human left ventricles after autopsy. METHODS Six water-filled (non-) aneurysmatic balloons of 150, 250, and 350 mL and 3 hearts of different sizes and shapes were suspended upright in a water ba...

the ground state rotational bands of some rare earth nuclei show a rather strange behaviour at large values of angular momenta. the nuclear moment of inertia teta increases smoothly with angular momentum i up to i=12. then at about i=14 there is a sudden increase in the moment of inertia. the plot of teta versus the square of the angular velocity w gives a s-shaped curve. we attempt here to rep...

in this research, the compositing of the surface of az31b magnesium alloy with cnt was studied by fsp. the parameters under study were rotational speed (500-1500 rpm), transverse speed (12-44 mm/min), number of passes (1-4), and cnt weight fraction (0-2%). microhardness testing, optical metallography, fesem, and eds analysis were employed for the characterization of the samples. the suitable li...
