The Wartegg drawing completion test (Wartegg Zeichen Test, WZT) is a projective drawing test developed in the 1920’s and 1930’s by the AustroGerman psychologist Ehrig Wartegg (Wartegg, 1939). The standard DIN-A4sized test form has eight white, 4cm-by-4cm squares in two rows on a black background (Figure 1). Each square is blank except for a small sign, such as a dot or a line, that is given as ...

Two different groups of subjects had to adjust two-dimensional stimuli, differing in size, shape and type (dot patterns or irregular contour figures), within a reference circle. The two groups performed under two different instructions. The first instruction stressed matching the centres of the stimulus and the circle, while the second required simply positioning the test stimulus in the middle...

Rotating outline squares and circles were viewed through a sunburst pattern of stationary radial slits. At slow rotation rates the (dotted) square was perceived globally as a single rotating shape, and at higher rates, as a set of independent local dots moving in and out radially. An eccentrically rotating circle was seen as a dotted circle; the dots comprising the circle actually moved in and ...

This paper is an investigation into the use of real-time image enhancement for improved road sign classification. In particular we observe speed signs tracked using a circle detector in image sequences to improve image quality for classification. We concentrate on a fast technique capable of running at frame rate. Finally, we show that reliable sign classification is possible earlier using supe...

The mechanisms of moire occurrence during dot-to-dot printing for various forms raster elements (circle, square, rhombus, ellipse) are considered. algorithms calculating the areas common overlay neighboring inks round, square and rhombic form presented. An algorithm methodology ellipsoidal with arbitrary misalignment along coordinate axes has been developed. program code ellipses using Pascal 7...

On physical examination, a soft elastic mass was noted on the distal volar aspect of her forearm...

The transfer of charge between different regions of a phase-coherent mesoscopic sample is investigated. Charge transfer from a side branch quantum dot into a ring changes the persistent current through a sequence of plateaus of diamagnetic and paramagnetic states. In contrast, a quantum dot embedded in a ring exhibits sharp resonances in the persistent current, whose sign is independent of the ...

If one drops the unicity assumption, (C(D)) is the property of having constant diameter, which is in fact equivalent (for closed curves in the plane) to having constant width or constant breadth (for the definitions and the proof of the equivalence, see [8, chap. 25]). It is a surprise to many (including me !) that curves of constant diameter other that the circle do exist. The simplest example...

the hermeneutic circle articulated by different hermeneuticans in various versions is one of the basic problems in modern hermeneutics. romanic hermeneutics introduced the circle as a methodological principle, but in philosophical hermeneutics the circle has ontological dimensions and regards as a process of understanding. heidegger believes that hermeneutic circle reflects dasein’s existential...

We review the construction of integral Apollonian circle packings. There are a number of Diophantine problems that arise in the context of such packings. We discuss some of them and describe some recent advances. 1. AN INTEGRAL PACKING. The quarter, nickel, and dime in Figure 1 are placed so that they are mutually tangent. This configuration is unique up to rigid motions. As far as I can tell t...
