The study of geometries is the study of a set of axioms concerning abstract quantities called points, lines, and flats. The axioms are usually framed to satisfy some geometric notions, and there is a considerable interplay between the algebraic and geometric properties of such systems. The ...
asuch as the Szemerédi–Trotter theorem on point-line incidences [37], the Crossing Lemma [5,27], incidences between curves and points and tangencies between curves and lines, extremal graph theory [26], quasi-planar graphs [3], Minkowski-type constructions, repeated distances on the sphere...

Lance added that it is “Interesting to compare [the Heinemann font] to the Magma family designed by Summer Stone, former director of the Adobe font program. The “child-safe†font in the Magma family is called Tuff.†He points out that Tuff’s Roman...
acting as attention attractors to the words and meanings with which they were co-expressed. Research on the relationship between beat gestures, prosody, and speech perception provides evidence for the integration of beats and speech at the time of conceptualization. However, missing from research on...
FIG. 2 shows the block diagram of a control device for a control element 1 such as a thyristor or a transistor placed between a mains supply 2 and a lead 3. A calculating block 4 receives at 5 the voltage of the mains supply 2 and calculates the integral of a function of that supply...

Differential properties between the observed values were used in the method. Starting from the analytic relations rA = rA(t) and cA = cA(t), which can be very complex (polynomes of the n-th order), and, eliminating time t in order to give a full description of the process, we ...
