High-energy physics: Machines shut down

Support Vector Machines in High Energy Physics

This lecture will introduce the Support Vector algorithms for classification and regression. They are an application of the so called kernel trick, which allows the extension of a certain class of linear algorithms to the non linear case. The kernel trick will be introduced and in the context of structural risk minimization, large margin algorithms for classification and regression will be pres...

Shut Down, Don't Stress Out

Chemical reactions lie at the heart of many biological processes, from photosynthesis and respiration to cell signaling and drug metabolism. Thanks to an atmosphere rich in oxygen, many organisms use oxygen to carry out these life processes. But oxygen metabolism produces highly toxic by-products called reactive oxygen species. When oxidation outpaces detoxifying reactions, oxidative stress occ...

Scheduling Jobs Before Shut-Down

Distributed systems execute background or alternative jobs while waiting for data or requests to arrive from another processor. In those cases, the following shut-down scheduling problem arises: given a set of jobs of known processing time, schedule them on m machines so as to maximize the total weight of jobs completed before an initially unknown deadline. We will present optimally competitive...

High Energy Physics,horizons*

The previous sessions have borne witness to the fact &at high energy accelerator and storage ring technology is a.subject of continuing vitality. Nothing dramatizes this more convincingly than the chart (Fig. 1) which shows the growth in energy of the world’s accelerators in time. If one includes in this chart the equivalent laboratory energy of existing and projected colliding beam storage rin...
