Lights in the Shadows, 3D-modelling knots with MOCASSIN
Most of the enveloppes of Planetary Nebulae (and other objects like novae) are far from beeing homogeneous: clumps, knots and tails are often observed. We present here the first attempt to build a 3D-photoionization model of a knot and the corresponding tail, ionized by diffused radiation issuing from surrounding material.
متن کاملUtility of Complex Alternatives in Multiple-Choice Items: The Case of All of the Above
This study investigated the utility of all of the above (AOTA) as a test option in multiple-choice items. It aimed at estimating item fit, item difficulty, item discrimination, and guess factor of such a choice. Five reading passages of the Key English Test (KET, 2010) were adapted. The test was reconstructed in 2 parallel forms: Test 1 did not include the abovementioned alternative, whereas Te...

متن کاملThe Pendulum Weaves All Knots and Links
The behavior of a dissipative chaotic dynamical system is determined by the skeleton of its strange attractor, which consists of an uncountably infinite set of unstable periodic orbits. Each orbit is a topological knot, and the set is an infinite link. The types of knots and links supported by the system may be determined by collapsing the attractor along its local stable manifolds to form a te...
متن کاملTheories, Boundaries, and All of the Above
The challenge on the horizon for computer-mediated communication has to do with the refinement of theories. The most important refinement we need has to do with the articulation of boundary conditions: implicit boundaries that have always been there but which we have ignored or failed to investigate, and explicit boundaries being foisted upon us by technological developments that may limit (or ...
