Lecture 14 : k - center Problem

Given a set P of n points in R, a typical clustering problem asks for partitioning P into a family of k subsets {P1, . . . , Pk}, so that a certain objective function is minimized. The objective function depends on the application and varies. A typical clustering problem is the so-called centered clustering problem in which a representative point ci (or a q-flat) is chosen for each cluster Pi a...

14-De­oxyxyloccensin K from Chisocheton ceramicus (Meliaceae)

The title limonoid 14-de-oxyxyloccensin K, C(27)H(34)O(7), isolated from Chisocheton ceramicus (Meliaceae), features an oxygen linkage between carbon-3 and carbon-8 along with a tetra-hydro-furyl sub-unit. The six-membered rings adopt chair configurations and the tetra-hydro-furyl sub-unit has an envelope shape.

Online Algorithms and the k - server problem — June 14 , 2011

Finally, we wrap-up this lecture with our new result which achieves a competitive factor of Õ(log k log n) for the k-server problem on n nodes1. This is joint work with Nikhil Bansal, Niv Buchbinder, and Aleksander Madry. Our basic approach is based on the framework of [CMP08]. The key idea in our work is that instead of using the allocation problem (as suggested by [CMP08]), we use the fractio...

This case study provides an in-depth analysis of Siemens' lessons learned when implementing knowledge management. For the analysis of the case-study data, we use established tools from the marketing literature, and integrate these with the change management literature. The aim is to provide a rich-yet-parsimonious conceptualisation of Siemens' lessons learned in dealing with two distinct implem...
