This is a short paper introducing pitfalls when implementing averaged scores. Although, it is common to compute averaged scores, it is good to specify in detail how the scores are computed.

We prove orthogonality relations for some analogs of trigonometric functions on a q-quadratic grid and introduce the corresponding q-Fourier series. We also discuss several other properties of this basic trigonometric system and the q-Fourier series.

We present an analysis of 15 Chandra observations of the nearby spiral galaxy M81 taken over the course of six weeks in 2005 May–July. Each observation reaches a sensitivity of ∼1037 erg s−1. With these observations and one previous deeper Chandra observation, we compile a master source list of 265 point sources, extract and fit their spectra, and differentiate basic populations of sources thro...

This demo will present the logging facilities to capture the user context within the Daffodil framework during a live search in computer science data sources. We propose to use the Daffodil system as an experimental framework for the evaluation and research of interactive IR. The system already provides a rich set of working services and available information sources. These services and sources...

In typical machine vision problems such as quality control or object location, it is often the case that elements of interest are small protuberances over a surface. We present an innovative and robust approach aiming at detecting such protuberances. Its basic ideas are: a) to detect the shadows produced by the protuberances, b) to use several light sources simultaneously to enhance detection. ...
