The Chatterton Astronomy Department of Sydney University, in collaboration with the Group Imperial College (London), has carried out a program speckle interferometry on 3.9 m Anglo-Australian Telescope (AAT). Over 2 km film were exposed during two observing sessions November and December, 1978, analysis this very large amount data is being at present time.
The correlation curve measured with an intensity interferometer has a shape out to its first minimum which is insensitive the brightness distribution across star. Observations are therefore initially interpreted in terms of angular diameter equivalent uniform disc. necessary correction obtain true limb-darkened may be made by means approximate formula and limb-darkening coefficient µ λ . More precise corrections, used analysing results from Narrabri Observatory, given for grid model stellar...
Combinatorial problems are formulated to find optimal designs within a fixed set of constraints. They commonly found across diverse engineering and scientific domains. Understanding how best use quantum computers for combinatorial optimization is date an open problem. Here we propose new methods producing approximate solutions the maximum cut problem its weighted version, which based on relaxations local Hamiltonians. These defined through commutative maps, in turn constructed borrowing...
In September 1996, a panel of experts on solar cycle prediction techniques met in Boulder, Colorado, to survey forecasts and geomagnetic activity arrive at consensus how the will develop. After two weeks deliberation, 12 scientists (from Australia, Germany, United Kingdom, States) agreed that large amplitude with smoothed sunspot maximum approximately 160 is probable near turn century. The predicted comparable previous cycles (see Figure 1). Our ability predict crucial many technologies,...
Abstract Modeling electronic systems is an important application for quantum computers. In the context of materials science, open problem computational description chemical reactions on surfaces. this work, we outline a workflow to model adsorption and reaction molecules surfaces using computing algorithms. We develop compare two local embedding methods systematic determination active spaces. These are automated based physics molecule-surface interactions yield systematically improvable...

In light of the analogy between structure electrodynamics and fluid dynamics, equations motion may be reformulated as a set Maxwell equations. This has been explored in literature for incompressible turbulent flow compressible but not widely relation to plasmas. letter introduces analogous formulates plasma terms species canonical vorticity its cross product with velocity. The form source is presented magnetohydrodynamic (MHD) limit restores typical variety MHD waves.
Previous work recognized a new framework for the equations of multifluid plasma, wherein each species can be described by set remarkably similar to Maxwell classical electrodynamics. This paper extends previous effort form an exact isomorphism between theory and The major benefits formulation are that explicit coupling different is minimized, theorems techniques electrodynamics immediately applied formulation. We introduce investigate some immediate consequences from To provide visualization...

The equations of fluid dynamics governing an incompressible flow may be recast into the form a set Maxwell for Lamb vector and vorticity, which play role analogous to electric magnetic fields, respectively. challenge in utilizing this approach is that source terms, charge density current density, must known order solve directly. In paper, we explore construction terms laminar flow. To demonstrate utility approach, use newly formed common mathematical techniques borrowed from classical...
A solution procedure for the fully coupled Navier–Stokes and Maxwell equations is described. The approach implements a conservative fluid formulation in which Lorentz body force Ohmic heating terms are recast as convective terms. This removes explicit sources from equations, have previously introduced severe stiffness demanded very delicate numerical treatment. coupling with full enables displacement current effects, charge separation low-conductivity plasma behavior, electromagnetic wave...
