The final product is Cyberchase Fractions Quest—a math game based on the storyline of PBS children's television series, Cyberchase. In the game, students in grades 3 and 4 will apply learning fractions within three contexts: areas and regions (such as shapes), sets (groups of objects), and on a number line. The game will identify specific areas where students struggle and will introduce challeng ...

Recent advances in gas chromatographic and mass spectrometric techniques for atmospheric measurements have led to highly complex data sets that have overwhelmed the capabilities of current data analysis software. We propose a new method for the automated reduction of chromatographic data using peak-fitting algorithms. By relying upon constrained peak-fit parameterization, accuracy of peak identifi ...

We propose to develop and deliver a generalized 3DVAR data assimilation module, in an opensource and non-proprietary programming language, which is compatible with both ROMS and FVCOM and easily incorporated into the existing NOAA operational forecast system (OFS). Our innovation is to develop a data assimilation roadmap contrasting 3DVAR with other advanced techniques such as multi-scale 3DVAR, 4 ...

Tropospheric oxidation capacity is dominated by HOx photochemistry, however halogen atoms and oxides significantly affect these chemical cycles. A sensitive and robust measurement of gaseous HCl is critically important to improve our understanding of halogen chemistry and its impacts on the spatial and temporal oxidation capacity of the atmosphere. This is vital to evaluating the life time of shor ...

The DSOM system realized in a Phase II effort will provide a modular, compact and reconfigurable system with the ability to provide unique and new information about the scene of interest (e.g. temporal and height information) when compared with traditional SAR sensors. When compared with other imaging technologies, DSOM has the important advantages of being operable through cloud cover and at nigh ...

This project continues our development of innovative systems for farming macroalgae on the high seas. We will identify suitable sites in Nantucket Sound to demonstrate our system and determine the associated environmental parameters including depths, currents, and waves. By combining that information with load and acceleration data from our Phase I wave-basin tests, we will refine the structural d ...

This program is aimed at the development of a deployable sensor for direct measurement of carbonate ions in saline waters with a sensitivity of 5 μM. The sensor combines the selectivity of carbonate ionophore with the unique structure of a carbon nanotube array to achieve a large dynamic range, high specificity and sensitivity. Phase I was focused on demonstrating the proof-of-principle concept f ...

There is an urgent need to optimize antimicrobial dosing in order to address the prevalence of drug-resistant pathogens and the increase of minimum inhibitory concentrations (MICs) of antimicrobials. Antimicrobials typically have a narrow window of effective concentration or therapeutic indices. If the drug is dosed above this concentration window it becomes toxic. Conversely, if under-dosed, trea ...

To better understand the world around them, social scientists develop models and theories of human behavior and interaction that they empirically test through a variety of quantitative and qualitative techniques. However, current methodological paradigms often introduce biases through sampling constraints and data analysis techniques that make the results of social science experiments hard to repl ...

Boston Fusion Corp. and Arizona State University propose to research and develop Autonomous System Control via Social Insect Models (ASC-SIM). We will develop a unified approach that combines: swarm-based scenarios of national interest; predictive social insect models including an underlying ontology that incorporates insect, model, and scenario features; graph-based search to select the most app ...
