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 Mineralogy of Shock-Induced Melt Vein in Martian Meteorite Zagami: Shock Pressure and Ejection Mechanism
This is the first report of Post-stishovite was found in zagami meteorite in the maskelynite outside of shock-induced melt vein. The mineralogy assemblages of melt vein, including stishovite, pyroxene and…

Threshold Collision-Induced Dissociation of Hydrogen-Bonded Dimers of Carboxylic Acids
Energy-resolved competitive collision-induced dissociation is used to investigate the proton-bound heterodimer anions of a series of carboxylic acids (formic, acetic, and benzoic acid) and nitrous acid with their conjugate bases.

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 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…
