Universal Guard Problems ∗ Sándor
We provide a spectrum of results for the Universal Guard Problem, in which one is to obtain a small set of points (“guards”) that are “universal” in their ability to guard any of a set of possible polygonal domains in the plane. We give upper and lower bounds on the number of universal guards that are always sufficient to guard all polygons having a given set of n vertices, or to guard all poly...
متن کاملImre Bárány, Lecture 4
Let X ⊂ R d be a set of n points in general position (i.e. no d + 1 points of X lie on the same hyperplane.) For a positive 0 < ε < 1, we define A finite set S ⊂ R d is called a (weak) ε-net of X if S ∩ F = ∅ for any F ∈ F ε. We note that S is called a strong ε-net if, in addition, it also satisfies S ⊂ X. Since we are only going to discuss weak ε-nets, we will simply call these ε-nets. Our goa...
متن کاملProblems for Imre Bárány’s Birthday
Tverberg’s Theorem states the following: Let x1, x2, . . . , xm be points in R with m ≥ (r − 1)(d + 1) + 1. Then there is a partition S1, S2, . . . , Sr of {1, 2, . . . ,m} such that ∩j=1conv(xi : i ∈ Sj) 6= ∅. This was a conjecture by Birch who also proved the planar case. The bound of (r − 1)(d + 1) + 1 in the theorem is sharp as can easily be seen from configuration of points in sufficiently...

soil in which they were found but are the remains of animals living in the sea on whose bed the soil (sediment) was deposited. The latter paper is a summary of a projected further work which unfortunately never appeared. It is the Prodromus that contained the first statement of the Law of Superposition; and much more. 'If, in a certain stratum, we find great abundance of rushes, grass, pine con...
متن کاملA Compact Reformer for Portable Fuel Cells
A compact reformer to generate hydrogen for portable fuel cell applications is presented. This reformer is a conventional type single-path tubular reactor packed with granular catalyst particles in which steam reforming and catalytic partial oxidation reactions take place in series using a mixture of methanol and water as a feed. The novel feature of this reformer is in the interlacing of the f...
