Comparing Three Approaches To Preparing Teachers To Teach For Deep Understanding In Earth Science: Short-Term Impacts On Teachers And Teaching Practice
This study used an experimental design to compare the efficacy of three different approaches to professional development for preparing teachers to implement curriculum units aimed at teaching for deep conceptual…

Gender Differences In Science
We present a review of research that looks at alternative explanations for these gender differences in science. Specifically, we consider the significance of girls’ science attitudes and the pervasive influence—both…

Leaving Flatland: Realtime 3D Stereo Semantic Reconstruction
We report our first experiences with Leaving Flatland, an exploratory project which studies the key challenges in closing the loop on autonomous perception and action in challenging terrain.

Observations of Plasma Line Splitting in the Ionospheric Incoherent Scatter Spectrum
Wide-bandwidth ionospheric incoherent scatter (IS) spectra obtained using the Arecibo IS radar show the occurrence of a split in the plasma line (i.e., two plasma lines) when the plasma frequency…

The Hidden Permutation Model and Location-Based Activity Recognition
Abstract Permutation modeling is challenging because of the combinatorial nature of the problem. However, such modeling isoften required in many real-world applications, including activity recognition where subactivities are often permuted…

Wavelength Dependence of the Es Layer Instability, and of Coupling to the F Layer, in the Nonlinear Regime
We show that longer wavelengths grow to larger amplitudes before eventual nonlinear saturation, and couple more effectively to the F-region.

Collaborative Effects of Mobile Sensor Network Localization through Distributed Fusion of Multi-Modal Navigations
This paper addresses the problem of localizing both absolute and relative 3-D positions of mobile sensor network nodes by fusing inertial measurements and radio frequency (RF) ranging measurements.

A Multi-Sensor Model to Improve Automated Attack Detection
In this paper we investigate how to use the alerts from several audit sources to improve the accuracy of the intrusion detection system (IDS). Concentrating on web server attacks, we…

A Process Catalog for Workflow Generation
This paper describes PROCAT, an implemented ontology-based catalog for components, built on a layered representation that allows reasoning about processes at varying levels of abstraction, from qualitative constraints reflecting preconditions and…

The Use of a Nasal Resistance Valve to Treat Sleep Disordered Breathing
The present pilot study tests the hypothesis that the application of expiratory resistance via a nasal valve device would improve breathing during sleep in subjects with OSA and in primary…
