We study a variant of intersection representations with unit balls, that is, unit disks in the plane and unit intervals on the line. Given a planar graph and a bipartition of the edges of the graph into near and far sets, the goal is to represent the vertices of the graph by unit ...
Suppose that a connected planar simple graph has 20 vertices, each of degree 3. Into how many regions does a representation of this planar graph split the plane? (include the infinite face) ( ) A、10 B、11 C、12 D、13 点击查看答案&解析 手机看题 ...
In the context of intersection graph classes, much work has been devoted to efficiently computing arepresentation, which is a collection of sets or geometric objects having an intersection graph that is isomorphic to a given graph. For many well-known graph classes, such as interval graphs and c...
However, most common approaches do not provide good neighborhood and topology preservation if the logical structure of the input pattern is not known a priori. In fact, the most common approaches specify in advance the number of neurons in the network and a graph that represents topological relati...
properties, which consisted of three characteristic curves onCartesian coordinate system, named W-S curve M-K curve and R-Y curve. Afterwards, they presented a quantification of similarities analysis method based on the graph radius, angle and relative departure associated with DNA curve, ...
Very often a surface is given as the graph of a differentiable function z=h(x,y), where (x,y) belong to an open set U→ℜ2. It is, therefore, convenient to have at hand formulae for the relevant concepts in this case. To obtain such formulae let us parametrize the surface by ...
Hue and luminance contrast are basic visual features. Here we use multivariate analyses of magnetoencephalography data to investigate the timing of the neural computations that extract them, and whether they depend on common neural circuits. We show that

In my opinion, the best image would be a set of two dimensional images. Each image would have vertical and horizontal geodesic lines bulged out at the center where the Earth is. Geodesic lines always are planar and the plane intersects the center of the earth, so no information would be ...
We study the properties of Schnyder’s realizers and canonical ordering trees of plane graphs. Based on these newly discovered properties, we obtain compact drawings of two styles for any plane graph G with n vertices. First we show that G has a visibili
