OBJECTIVES Determine effects of a limited-enforcement intelligent tutoring system in dermatopathology on student errors, goals and solution paths. Determine if limited enforcement in a medical tutoring system inhibits students from learning the optimal and most efficient solution path. Describe the type of deviations from the optimal solution path that occur during tutoring, and how these devia...

In many situations we are faced with the need to estimate the number of classes in a population from observed count data: this arises not only in biology, where we are interested in the number of taxa such as species, but also in many other fields such as public health, criminal justice, software engineering, etc. This problem has a rich history in theoretical statistics, dating back at least t...

CASE SHOWING THE CONTAGIOUSNESS OF PHTHISIS. A man of thirty-four had been sick with phthisis about four years; gradually grew from bad to worse, until the usual end was reached. It was not until the last three or four months of his life that he was confined to his bed. He was fond of pets, and during these three or four mouths, it was hia fancy to have his dog in the room nearly all the time. ...

It is important to transmit pictures efficiently in most Web sites, especially for those users with low bandwidth connections. In this demonstration, we propose a system which progressively transmits images using a very low transmission rate (as low as 15% in some cases). The transmitted images maintain a reasonable picture quality for the users to browse images quickly. Interested readers can ...

Behavioral studies have shown that picture-plane inversion impacts face and object recognition differently, thereby suggesting face-specific processing mechanisms in the human brain. Here we used event-related potentials to investigate the time course of this behavioral inversion effect in both faces and novel objects. ERPs were recorded for 14 subjects presented with upright and inverted visua...

In this paper we are investigating the long time behaviour of the solution of a mutation competition model of Lotka-Volterra’s type. Our main motivation comes from the analysis of the Lotka-Volterra’s competition system with mutation which simulates the demo-genetic dynamics of diverse virus in their host : dvi(t) dt = vi [

In this paper the solutions to the optimal multiobjective H 2 / H D 0 problem are characterized using Banach space duality theory, and shown to satisfy a flatness or allpass condition. Dual and predual spaces are identified, and equivalent maximizations formulated therein. The duality description leads naturally to a solution based on convex programming.

We present noWorkflow, an open-source tool that systematically and transparently collects provenance from Python scripts, including data about the script execution and how the script evolves over time. During the demo, we will show how noWorkflow collects and manages provenance, as well as how it supports the analysis of computational experiments. We will also encourage attendees to use noWorkf...
