For a permutation p, let S_n(p) be the number of permutations on n letters avoiding p. Stanley and Wilf conjectured that S_n(p)^{1/n} tends to a finite limit L(p) for each permutation p. Marcus and Tardos proved the Stanley-Wilf conjecture by a remarkably simple argument. Backed by numerical evidence, it has been conjectured by various researche...

Szemerédi's regularity lemma is one of the most powerful toolsin graph theory, with many applications in combinatorics, number theory,discrete geometry, and theoretical computer science. Roughly speaking, itsays that every large graph can be partitioned into a small number of partssuch that the bipartite subgraph between almost all pairs of part...

1) We analyze the different tradeoffs and goals of Grid, Cloud and parallel (cluster/supercomputer) computing. 2) They tradeoff performance, fault tolerance, ease of use (elasticity), cost, interoperability.3) Different application classes (characteristics) fit different architectures and we describe a hybrid model with Grids for data, tradition...

This talk gives a guided tour through examples and indicative theory that highlight two important topics that are typically omitted from applied mathematics or engineering training. The first is an appreciation for the calculus of distributions, that is different to the calculus of functions. That implies that inference in the presence of uncert...

This is a technical talk on the recent marginal-then-conditional sampler for hierarchical Bayesian models. Bayesian models for inverse problems naturally have a hierarchical structure in which the data model depends on a high-dimensional latent structure, which in turn depends on a low-dimensional hyperparameter vector. In the linear-Gaussian ca...

Sample-based inference is a great way to summarize inverse and predictive distributions arising in large-scale applications. The best current technology for drawing samples are the MCMC algorithms, with the latest algorithms enabling comprehensive solution of substantial geophysical problems. However, for the largest-scale applications the geome...

Blueprint for a concrete dam at Allandale Farm in Duluth, Minnesota. Included are a Plan of Dam, Elevation of Downstream Side of Dam, Plan and Elevation of Spillway, Section Thru Wing, Elevation of Wing Walls, and Section Thru Dam. "Duck Pond Dam, Allandale" is written on the back of the blueprint. Allandale Farm was owned by the Hartley family.

A subspace arrangement is a union of a finite number of subspaces of avector space. We will discuss the importance of subspace arrangements firstas mathematical objects and now as a popular class of models forengineering.We will then introduce some of new theoretical results that were motivatedfrom practice. Using these results we will address t...

Mathematics in sports covers a wide range of aspects, from the study of dynamical systems (to assess biological response to fatigue, for instance), the mechanics of biological tissues (like in injury studies), game theory (for strategy planing), up to the dynamics of fluids and structures to optimise the performance of sport devices (ski, racing...

In this talk we will describe the derivation of mathematical and numerical models for the simulation of high performance rowing boats. Rowing boats are a complex dynamical system strongly affected by the rowers action and movements. Indeed a rowing boat hardly moves with constant speed, but it is instead subject to a complex system of secondary ...
