Computing the Average Height in Trace Monoids
, 2001
"... The height of a trace is the height of the corresponding heap of pieces in Viennot's representation, or equivalently the number of factors in its CartierFoata decomposition. Let h(t) and jtj stand respectively for the height and the length of a trace t. We prove that the bivariate commutat ..."
Abstract
 Add to MetaCart
commutative series t x is rational, and we give a finite representation of it. We use this result to obtain precise information on the asymptotics of the number of traces of a given height or length. Then, we study the average height of a trace for various probability distributions on traces
Asymptotics of the average height of 2watermelons with a wall
 ELEC.J.COMBIN.14 (2007) R64; MATH.CO/0607163; MR2350454
, 2007
"... We generalize the classical work of de Bruijn, Knuth and Rice (giving the asymptotics of the average height of Dyck paths of length n) to the case of p–watermelons with a wall (i.e., to a certain family of p nonintersecting Dyck paths; simple Dyck paths being the special case p = 1.) An exact enumer ..."

On the Average Height of bBalanced Ordered Trees
"... Abstract. An ordered tree with height h is bbalanced if all its leaves have a level ℓ with h − b ≤ ℓ ≤ h, where at least one leaf has a level equal to h − b. For large n, we shall compute asymptotic equivalents to the number of all bbalanced ordered trees with n nodes and of all such trees with he ..."

with height h. Furthermore, assuming that all bbalanced ordered trees with n nodes are equally likely, we shall determine the exact asymptotic behaviour of the average height of such a tree together with the variance. 1
Insights from a Millennium of Average Heights in Northern Europe

This essay places the debate over human welfare during industrialization in the context of very longterm economic developments by examining an important aspect of living standardshealth and nutritionsince the Middle Ages. I use average stature determined from military records along with a negle ..."

neglected source, skeletal data. Average heights fell from an average of 173.4 centimeters in the early Middle Ages to a low of 165.8 centimeters during the seventeenth and eighteenth centuries. This decline of 7.6 centimeters exceeds by a factor of two any downturns found during industrialization
An extended set of Haarlike features for rapid objection detection
 IEEE ICIP
"... Recently Viola et al. [5] have introduced a rapid object detection scheme based on a boosted cascade of simple feature classifiers. In this paper we introduce a novel set of rotated haarlike features. These novel features significantly enrich the simple features of [5] and can also be calculated ef ..."

efficiently. With these new rotated features our sample face detector shows off on average a 10 % lower false alarm rate at a given hit rate. We also present a novel post optimization procedure for a given boosted cascade improving on average the false alarm rate further by 12.5%. 1
Liquidity Risk and Expected Stock Returns
, 2002
"... This study investigates whether marketwide liquidity is a state variable important for asset pricing. We find that expected stock returns are related crosssectionally to the sensitivities of returns to fluctuations in aggregate liquidity. Our monthly liquidity measure, an average of individualsto ..."

2003: Global analyses of sea surface temperature, sea ice, and night marine air temperature since the late Nineteenth Century
 J. Geophysical Research
"... data set, HadISST1, and the nighttime marine air temperature (NMAT) data set, HadMAT1. HadISST1 replaces the global sea ice and sea surface temperature (GISST) data sets and is a unique combination of monthly globally complete fields of SST and sea ice concentration on a 1 ° latitudelongitude grid ..."

Ensemble Methods in Machine Learning
 MULTIPLE CLASSIFIER SYSTEMS, LBCS1857
, 2000
"... Ensemble methods are learning algorithms that construct a set of classifiers and then classify new data points by taking a (weighted) vote of their predictions. The original ensemble method is Bayesian averaging, but more recent algorithms include errorcorrecting output coding, Bagging, and boostin ..."
