On using Directional Information for Parameter Space Decomposition in Ellipse Detection
No full textIn this paper we use the parametric polar representation to extend the application of edge directional information from circle to ellipse extraction. As a result we obtain a mapping which decomposes the parameter space required for ellipse extraction into two independent sub-spaces and one final histogram accumulator. The mapping includes the tangent of the angle of the first and second directional derivatives. These tangents are computed by considering edge direction at two border points. We show that the use of gradient information for parameter space decomposition avoids the intensive point labelling imposed by geometric constraints used by other approaches
The effect of earlier puberty on cardiometabolic risk factors in Afro-Caribbean children
No full textAn earlier onset of puberty is associated with increased cardiometabolic risk. We investigated whether this relation was independent of faster childhood growth or current size in an Afro-Caribbean birth cohort (n=259). Anthropometry was measured at birth and then 6-monthly. Tanner staging started at age 8 years. Cardiometabolic risk factors were measured at mean age 11.5 years. In boys, pubarchal stage and testicular size were associated with lower high-density lipoprotein cholesterol, higher systolic blood pressure, and higher homeostasis model assessment of insulin resistance score, but not after adjusting for current body mass index (BMI) or rate of growth (up to age 8 years). In girls, earlier menarche and greater breast development were associated with higher fasting glucose even after adjusting for current BMI or prior growth. Pubarchal stage was associated with systolic blood pressure, even after adjusting for current BMI and prior growth. We concluded that earlier puberty is independently associated with cardiometabolic risk in girls but not in boys
Large-scale patterns in turbulent Rayleigh-Bénard convection in very large aspect ratio cells
No full textLarge-scale patterns, which are well-known from the spiral defect chaos regime of thermal convection at Rayleigh numbers Ra 105. They are uncovered when the turbulent fields are averaged in time and turbulent fluctuations are thus removed. We apply the Boussinesq closure to calculate turbulent viscosities and diffusivities, respectively. The resulting turbulent Rayleigh number Ra_, that describes the convection of the mean patterns, is indeed in the spiral defect chaos range. Interestingly, the turbulent Prandtl numbers are smaller than one with 0:2 _ Pr_ _ 0:4 for Prandtl numbers 0:7 _ Pr _ 10. Finally, we demonstrate that these mean flow patterns are robust to an additional finite-amplitude side wall-forcing when the level of turbulent fluctuations in the flow is sufficiently high

Reynolds number effect on 3D turbulent offset jet reattaching to a free surface
No full textExperimental study was carried out to investigate the effect of Reynolds number on 3D offset jet reattaching to above free surface. Sharp edged square nozzle was used to produce the jets, and the measurements were performed at the following six different Reynolds numbers: 2300, 3700, 5100, 7900, 10300 and 11900. Detailed velocity measurements were made in the symmetry plane. From the PIV data, the mean velocity and turbulence statistics were obtained to study the effects of Reynolds number on the salient features of the jet flow. Preliminary results on streamwise mean velocity decay along the nozzle centerline, contours of streamwise mean velocity and Reynolds shear stress are presented herein

Kings Cascades, Prince Regent River: 1 ♂, 2 ♀♀, 17 August 1994, L. Mueller leg. (ANIC). Distribution. North and north-east of Australia, New Caledonia. Diagnostic characters: Postfrons with dark T-mark. Both Hw with space between CuP and A1 basally not expanded and without double cells in proximal half. Generally more than 10 denticles along genital fossa rather close to it, rather regularly spaced and often not restricted to posterior portion. Superior anal appendages very slender, almost straight, clubbed, with apical portion approximately 1.5 times basal width and with apex narrowly curved postero-laterally into a moderately long acute point; inferior anal appendage distinctly shorter than 1/3 the length of superiors, with lateral edges of basal portion convex and rather abruptly narrowing into a distinctly tapered apical portion. Generally distinguished from G. rosenbergi, with which it overlaps in Australia, by (1) having more denticles (8–30) along genital fossa that are often not restricted to the posterior part, (2) straighter, more sharply pointed superior anal appendages and (3) by the shorter, more distinctly tapered apical portion of the shorter inferior appendage. Distinguished from G. amphora, with which it probably does not overlap in range, by (1) only 2 rows of cells between anal triangle and anal loop in Hw, (2) by lack of a pale mid-dorsal pattern element in S2 and (3) by the much slimmer posterior part of S3.Published as part of Theischinger, Gunther, Marinov, Milen, Bybee, Seth, Jensen, Colin, Theuerkauf, Jörn & Rashni, Bindiya, 2020, The genus Gynacantha Rambur, 1842 in the South Pacific (Odonata: Anisoptera: Aeshnidae), pp. 171-195 in Zootaxa 4778 (1) on pages 175-176, DOI: 10.11646/zootaxa.4778.1.7, http://zenodo.org/record/382369
The Benefits of Being Economics Professor A (and not Z)
No full textAlphabetic name ordering on multi-authored academic papers, which is the convention in the economics discipline and various other disciplines, is to the advantage of people whose last name initials are placed early in the alphabet. As it turns out, Professor A, who has been a first author more often than Professor Z, will have published more articles and experienced afaster growth rate over the course of her career as a result of reputation and visibility. Moreover, authors know that name ordering matters and indeed take ordering seriously: Several characteristics of an author group composition determine the decision to deviate from the default alphabetic name order to a significant extent.performance measurement, incentives, economists, name ordering
