In this report we describe the QALC system (the Question-Answering program of the Language and Cognition group at LIMSI-CNRS) which has been involved in the QA-track evaluation at TREC8. The purpose of the Question-Answering track is to nd the answers to a set of 200 questions. The answers are text sequences extracted from the volumes 4 and 5 of the TREC collection. All the questions have at le...

In this paper, we describe the system and methods used for the CLARITECH entries in the TREC–7 Filtering Track. Our main aim was to study algorithms, designs, and parameters for Adaptive Filtering, as this comes closest to actual applications. For efficiency's sake, however, we adapted a system largely geared towards retrieval and introduced a few critical new components. The first of these com...

Wire and arc additive manufacturing (WAAM) has proven that it can produce medium to large components because of its high-rate deposition potentially unlimited build size. Like all (AM) technologies, however, an optimized process planning provides uniform, defect-free is key for the production parts. Moreover, AM, particularly WAAM, no longer just a prototyping technology, most today's attention...

This study sought to identify specific types of discussion-based strategies that two successful high school physics teachers using a model-based approach utilized in attempting to foster students’ construction of explanatory models for scientific concepts. We found evidence that, in addition to previously documented dialogical strategies that teachers utilize to engage students in effectively c...

2. Do I hold in my hand the truly appropriate remedy for that lack ? 3. Is the preparation stable, active, pure, and uniform ? 4. Can I accurately determine the dosage ? 5. Is the preparation smoothly active when administered by the route I propose ? 6. Are ill-effects impossible ? Even if these questions cannot be answered in the affirmative, he gives the prescriber one more chance, provided t...

We propose a robust droplet fusion and sorting method for two parallel trains of droplets that is relatively insensitive to frequency and phase mismatch. Conventional methods of droplet fusion require an extremely precise control of aqueous/oil flows for perfect frequency matching between two trains of droplets. In this work, by combining our previous two methods (i.e., droplet synchronization ...

Despite its late arrival, Radiology (Imaging) has had a dramatic impact on patient care from both the diagnostic and therapeutic viewpoints. Singapore was one of the early users of the "new rays". This article briefly traces the early history of Radiology in Singapore and tracks the teaching and training given to medical students at the Faculty of Medicine. While its instructional components ha...
