Mathematical formula for the perfect Christmas tree

by Laura Domela

For those who prefer something more traditional than the Treeasy, members of the University of Sheffield’s Maths society have devised a formula for the perfect Christmas tree in response to a challenge by U.K. department store Debenhams.

The formula, which was created by students Nicole Wrightman and Alex Craig, uses the height of a tree to calculate the ideal number of baubles, length of tinsel, length of lights and even the height of the star, fairy or angel sitting atop the tree required to give the tree that catalog-perfect look.

Shift Left with Calibre Pattern Matching: Trust in design practices but verify early and frequently

Sponsored by Siemens Digital Industries Software

As integrated circuit (IC) designs become increasingly complex, early-stage verification is crucial to ensure productivity and quality in design processes. The "shift left" verification approach, enabled by Siemens’ Calibre nmPlatform, helps IC design teams to identify and resolve critical issues much earlier in the design cycle.
