De-Correlating CNN Features for Generative Classification
The proposed approach to solving this problem builds on the idea of training LDA classifiers using only class specific foreground images and a large collection of unlabelled images.

Effects of Tidal Forcing, Conductivity Gradient, and Active Seeding on the Climatology of Equatorial Spread F over Kwajalein
ESF climatology over the Kwajalein Atoll was compared with properties of the postsunset rise (PSSR) of the F layer and seeding activity in the troposphere.

Feature Fusion by Similarity Regression for Logo Retrieval
We propose a simple yet effective multi-feature fusion approach based on regression models for logo retrieval.

Spacetime Stereo and 3D Flow Via Binocular Spatiotemporal Orientation Analysis
This paper presents a novel approach to recovering estimates of 3D structure and motion of a dynamic scene from a sequence of binocular stereo images.

Comparative Analysis of Knowledge Representation and Reasoning Requirements across a Range of Life Sciences Textbooks
(Previously) we showed that embedding the knowledge representation and question-answering abilities in an electronic textbook helped to engage student interest and improve learning. A natural question that arises from this…

Investigation of Sudden Electron Density Depletions Observed in the Dusk Sector by the Poker Flat, Alaska Incoherent Scatter Radar in Summer
This paper investigates unusually deep and sudden electron density depletions (troughs) observed in the Poker Flat (Alaska) Incoherent Scatter Radar data in middle summer of 2007 and 2008.

Ionospheric Sounding Using Real-Time Amateur Radio Reporting Networks
Amateur radio reporting networks, such as the Reverse Beacon Network (RBN), PSKReporter, and the Weak Signal Propagation Network, are powerful tools for remote sensing the ionosphere.

A Distributed Computing Model for Dataflow, Controlflow, and Workflow in Fractionated Cyber-Physical Systems
In this paper we present the theory of a new distributed computing model for such systems as a first step toward a model-based design methodology for FCPS.

Conservative Groupoids Recognize Only Regular Languages
The notion of recognition of a language by a finite semigroup can be generalized to recognition by finite groupoids, i.e. sets equipped with a binary operation ‘⋅’ which is not…

Co-Location-Resistant Clouds
We consider the problem of designing multi-tenant public infrastructure clouds resistant to cross-VM attacks without relying on single-tenancy or on assumptions about the cloud's servers.

Control Systems Security from the Front Lines
As part of this special issue on control systems for the energy sector, guest editors Sean Peisert and Jonathan Margulies put together a roundtable discussion so readers can learn about…
