Instruction Sets Mixed - Width
A pplications written for the embedded domain must perform under the constraints of limited memory and limited energy. While these constraints have always existed, current trends, such as mobile computing and ubiquitous computing, bring more and more complex applications to the embedded domain, making performance, or speed of execution, an important factor as well. For instance, we are now able...
متن کاملConvex sets of constant width
A bounded convex set has constant width d iff any two parallel (and nonidentical) tangent planes to it have identical distance d from each other. Clearly balls have this property, but there are also other sets of constant width. This lecture was originally designed for a general audience as part of a series of lectures during the German “Year of Mathematics” 2008. It starts by presenting eviden...
متن کاملWhat is river health?
1. Traditionally the assessment of river water quality has been based solely on the measurement of physical, chemical and some biological characteristics. While these measurements may be efficient for regulating effluent discharges and protecting humans, they are not very useful for large-scale management of catchments or for assessing whether river ecosystems are being protected. 2. Measuremen...
متن کاملFamilies of sets with locally bounded width
A family of sets F is locally k-wide if and only if the width (as a poset ordered by inclusion) of F x = fU 2 F j x 2 U g is at most k for every x. The directed covering graph of a locally 1-wide family of sets is a forest of rooted trees. It is shown that if F is a locally k-wide family of subsets of f1; : : : ; ng, then jFj (2k) k?1 n. The proof involves a counting argument based on families ...
متن کاملConvex Sets of Constant Width and -diameter
PETER HÄSTÖ, ZAIR IBRAGIMOV AND DAVID MINDA ABSTRACT. In this article we study -diameter of planar sets of constant width. We obtain analogues of the isodiametric inequality and the Blaschke-Lebesgue Theorem for -diameter of constant width sets. Namely, we prove that among all the sets of given constant width, disks have the smallest -diameter and Reuleaux triangles have the largest -diameter. ...
