The novelly designed optical sensor for autonomous ocean monitoring works on equilibrium principles. When the pH-sensitive reagent solution sitting behind a gas-permeable membrane is exposed to seawater, the CO2 molecules present in the seawater diffuse across the membrane into the reagent and induce a pH change. After equilibrium is reached, the fluorescence is measured and the pCO2 data are recovered from a calibration curve. A specific feature of our measurement technique is the use of excitation ratiometric approach. A violet LED (Light Emitting Diode) and a blue LED are used to excite the sensing reagent through an excitation filter and the pCO2 dependent emission is measured through an emission filter by a photodiode.

The broad objective of this grant was to develop a generally applicable theory of performance of information-level fusion that provides accurate prediction of post-fusion algorithm accuracy in uncertain environments. determines factors affecting fundamental performance tradeoffs, e.g., sample size, resolution, specificity, and sensitivity of sensors. specifies performance benchmarks allowing quantitative comparison of different fusion algorithms. provides guidelines for algorithm design and optimization. The effort focused on information theoretic fusion methods and our analysis was based on geometric properties of information. Our research has impacted application domains where information theoretic fusion is applied. These included georegistration, remote sensing, multimodality anomaly detection, visualization, and dimensionality reduction.

Posttraumatic osteoarthritis affects approximately 5.6 million Americans annually. Those affected are typically younger and more active than persons with primary osteoarthritis. Arthrodesis is the typical management option for persons with end-stage ankle and subtalar posttraumatic arthritis. Arthroplasty is typically reserved for elderly persons. The functional limitations resulting from any of these strategies make treatment of this young population challenging. Combat wounds frequently lead to severe lower extremity injuries. We present a series of patients with severe posttraumatic osteoarthritis of the ankle and subtalar joint after combat trauma. They were treated at our institution with an integrated orthotic and rehabilitation initiative called the Return To Run clinical pathway. This clinical pathway may serve as an alternative or adjunct to arthrodesis and arthroplasty for young patients with severe posttraumatic osteoarthritis of the ankle and subtalar joint.

Fiber-optic sensors can be used to measure a wide range of physical parameters, such as strain, temperature, pressure and other quantities by recording the changes in light intensity, phase, polarization or wavelength caused by these parameters in the fiber1-6. Compared to their electronic counterparts, fiber-optic sensors can provide numerous advantages. They are electromagnetically passive and immune to electromagnetic interference, which make them suitable for operation in environments with high and variable electric field 3. They are made from silica glass so they are chemically and biologically inert. Also, the small size of optical fibers, generally on the order of hundreds of micrometers in diameter, makes the fiber-optic sensors physically small and light in weight. They can also perform distributed measurement, in which the measurand can be determined as a function of position along the length of a fiber or at a number of pre-selected locations of the fiber.

Both the public sector and the military are working on developing drowsiness detection systems, as driver fatigue is a significant contributor to motor vehicle accidents. Individually, electroencephalography (EEG) and eye- tracking measures are tenuous indicators of driver fatigue and impairment. This project proposes to integrate multiple sensor modalities in order to improve drowsiness level assessment and driver performance prediction. There is substantial evidence supporting the correlation of alpha bursts in EEG (narrowband alpha power density increases lasting 500 ms to several seconds) and eye-tracking measures, such as pupil diameter and gaze distribution, with drowsiness. As a step towards multi-sensory data fusion, we aim to implement in real time an optimized version of an existing algorithm for the automatic detection of alpha bursts using a single EEG channel and ascertain correlations between alpha bursts, eye-tracking measures, and behavioral indicators of fatigue that include standard deviation of both lane position and acceleration. The ability to reliably detect alpha bursts in real-time combined with established correlations will allow an algorithm to accurately predict driver performance in a simulation environment.

This paper describes a part of the event extraction system which has been developed in collaboration with HP Labs Russia. The domain of input texts is business news feeds. One of the most important event participant types is 'Organization'. This paper is focused on the problem of organization names recognition in Russian news texts. Two approaches have been implemented. The first is dictionary-based. We propose an algorithm to make a dictionary from a set of legal body full names gathered from a government registry. The main problems with the dictionary matching are incorrect stemming and significant fraction of ambiguous names among dictionary entries. The second recognition approach is based on usage of local context clues and internal name words. These words constitute patterns which are intrinsic to organization names. These patterns enable recognition of non-dictionary names. We propose an algorithm to derive such patterns from the original dictionary.

The long-term goals of this project are to enable observations of pH in the ocean at depths to 2000 m using sensors deployed on autonomous platforms, particularly profiling floats of the type used in the Argo array. These systems will enable robust, basin-scale observations of changing pH driven by natural and anthropogenic processes. Develop a robust and stable pH sensor for deep-sea applications that is based on the Honeywell Durafet Ion Sensitive Field Effect Transistor (ISFET). The sensor should operate to depths of at least 2000 m. It should have a precision of 0.001 pH and a stability of 0.005 pH over periods up to 5 years throughout the oceanic temperature and salinity range. Capabilities will be demonstrated with deployments on four Webb Research Apex profiling floats.
