Having just returned from the Centers for Disease Control and American Sexually Transmitted Diseases Association (ASTDA) conference in Atlanta, I’m struck by the speed of technological change in how we collect, handle and use data. Many presentations addressed novel means of surveillance, and indeed addressed a wider variety of potential influences on sexual health than we usually consider— for...

Golf is a global sport with professional golfers playing on many organized tours throughout the world. The largest and most important tours for male professionals include the PGA Tour, European Tour, Japanese Tour and Asian Tour. The Official World Golf Ranking, or OWGR, is a system for ranking male professional golfers on a single scale. We say a ranking system is unbiased if otherwise identic...

The image grand tour is a method for visualizing multispectral or multiple registered images. In many settings, several registered images of the same scene are collected. This most often happens when multispectral images are collected, but may happen in other settings as well. A multispectral image can be viewed as an image in which each pixel has a multivariate vector attached. The desired goa...

A closed knight’s tour of a chessboard uses legal moves of the knight to visit every square exactly once and return to its starting position. In 1991 Schwenk completely classified the m × n rectangular chessboards that admit a closed knight’s tour. In honor of the upcoming twentieth anniversary of the publication of Schwenk’s paper, this article extends his result by classifying the i × j × k r...

Euler Tour trees are due to Henzinger and King [1] and are an alternative to link-cut trees for representing dynamic trees. Euler tour trees are simpler and easier to analyze than link-cut trees, but do not naturally store aggregate information about paths in the tree. Euler tour trees are well suited for storing aggregate information on subtrees, which is a feature we will use in the next sect...

In this paper we present Panormo a tour guide robot for the Botanical Garden of Palermo. Panormo is equipped with an emotional learning system that gives it the ability to learn the emotional evaluation for each incoming stimulus. This evaluation induces robot’s emotional states that drive its tour. The robot carries out a dramatization of the tour according to drama’s theory and its emotions. ...

In this paper we introduce a metric to compare events and episodes in the episodic memory system of a virtual agent. The agent, a virtual tour guide based on a belief – desire – intention cognitive architecture, uses his memories to improve the walks around a virtual city. The guide’s past experiences are memorized as events and organized into episodes. Each event is indexed along six dimension...

This paper presents the results of a project aiming to the development of an innovative web site related to the famous monumental complex Piazza dei Miracoli in Pisa. The website includes an innovative section containing an advanced Virtual Reality application, making use of a state-of-the-art 3d web technology. In this application users are able to explore the space and the history of the monu...

The (Euclidean) Vehicle Routing Allocation Problem (VRAP) is a generalization of Euclidean TSP. We do not require that all points lie on the salesman tour. However, points that do not lie on the tour are allocated, i.e., they are directly connected to the nearest tour point, paying a higher (per-unit) cost. More formally, the input is a set of points P ⊂ R and functions α : P → [0,∞) and β : P ...

This work suggests an adaptive tour planning multimedia system designed to meet the tour routing needs of different tourists. Tour planning is an application of vehicle routing problem. Meanwhile, vehicle routing problem is a ‘traveling salesman problem’ (TSP) type problem. TSP is an example of a combinatorial optimization problem and is known as NP-hard. As studied by many researchers exact, h...
