Decision support tools were developed in previous Florida Department of Transportation (FDOT) research projects to allow for better analysis and visualization of historical traffic and incident data, in support of incident management and traffic management centers (TMCs). The goal of this demonstration project is to implement the use of these decision support tools at a traffic management center in Florida and demonstrate the benefits of these tools in a traffic management center (TMC) environment. The TMC of FDOT District 5 was selected as the demonstration site. Three decision support functions were implemented for the I-4 corridor managed by FDOT District 5. These are normal day traffic pattern and parameter identification, incident impact estimation, and historical detector data play back using the Remote Traffic Microwave Sensor (RTMS) simulator.

The variable reluctance resolver (VRR) is commonly used in the automotive industry as a rotor position sensor. Its use in the Aerospace and Defense Industries has been limited due to inadequate accuracy performance. However, recent interest in the Aerospace Industry for VRRs as a viable alternative to conventional resolvers has driven the development of higher accuracy VRRs for use in angular position feedback applications. This paper presents the progression in the development of the VRR and provides information on the lessons learned during the completion of the first generation of single speed and multispeed engineering units of VRRs. This first generation of engineering units was evaluated to identify potential design and manufacturing process improvements. Incorporating the lessons learned from the development of the first generation units resulted in an improvement in performance and manufacturability in the second generation of VRRs, making it a desirable option for future use in commutation of brushless DC motors.

This the final report for a one-year effort to develop a high frame- rate multi-scale camera for investigations of fine-scale auroral dynamics and induced beam-plasma instabilities in the high-latitude ionosphere. The scope of the project included development and field-testing of the instrument, as well as development of an image processing framework for extracting physical parameters from the recorded measurements. The optical architecture consisted of a low-noise scientific-grade CMOS sensor coupled to a 140-mm f/1 optic through a prompt-emission notch filter. This design provided meter-scale spatial resolution at 120-km stand-off distance over an 8x6 degree field-of-view. 16-bit sampling provided the large dynamic range required to observe the full range of variability in the aurora. A lower resolution wide-field sensor provided contextual information and the acquisition trigger for the CMOS sensor. Triggering was accomplished via real-time analysis of intensity and motions of targets within the field. Initial observations from the Sondrestrom, Greenland, ionospheric research facility have provided compelling proof-of-concept in support of a broader science program, as discussed in this report.

This research program has been focused on advanced technologies for detection and discrimination of military munitions. The underlying premise of the program has been that there is an inherent limitation in the information content associated with magnetometer and EMI sensors deployed for UXO cleanup. To optimize UXO classification one must integrate all available information, both within the measured data itself and within a priori knowledge one may possess. An important class of prior knowledge is represented by the sensor physics, and by placing as much physics as possible into the models and classification features, one removes the need to rely on the limited sensor data to infer such phenomenology. Statistical classifiers are also required to maximize the information extracted from the measured data to infer the unknown model parameters. Further, the statistical classifiers may be used to appropriately exploit other forms of information inherent to the data. For example, while performing classification one may exploit the contextual information provided by all of the unlabeled data at a given site, while also appropriately leveraging related information in data measured at previous sites.

One of the major products the AF is looking for is a lightweight, reconfigurable electro-optic sensor system. Towards that end, we are investigating the possibilities of incorporating a protection layer, an optical signal amplification layer, a detection layer, a solid-state cooling layer, and a readout electronics layer all monolithically integrated within a single pixel of a semiconductor focal plane array (for vast reductions in size and weight). When completed, the microscopic theory that arises from this project will be applicable to each of the various layers of the super-pixel device for both further understanding of the quantum mechanical processes involved, as well as for greatly improving the performance of each layer. This theory will be applied to quantum-kinetic studies of laser damage of semiconductor photodetectors, in order to describe and understand all radiation damage mechanisms so that methods of mitigation can be developed for the protection layer of the monolithic sensor. This theory will be applied to describing and predicting the optical control of scattering-induced dephasing for optical signal amplification in photodetectors using electronic quantum interference, as well as for noise reduction in both detectors and electronics. This theory will be applied to the photo-carrier generation and transport processes involved within the detection layer, for improving performance by minimizing dark-current noise. This theory has already been applied to photoluminescent cooling of detectors; a vibrationless, low-cost, extremely low-volume and weight on-chip solid-state cryogenic cooling scheme for space sensors. Finally, this theory will be applicable to high-power and ultrafast electronics development.

A novel Shape Memory Alloy (SMA) has been developed as an alternative to currently available alloys. This material, called SMARQ, shows a higher working range of temperatures with respect to the SMA materials used until now. This temperature restriction is one of the most critical limitations of the current SMA devices for their use in space and other applications. A full characterization test campaign has been completed in order to obtain the main material properties and check its suitability for usage as an active material in space actuators. Results of this characterization test campaign have been presented in this work. This new alloy has been proposed for its use as actuators for space mechanisms. One application of SMA technology is an ultra-low-weight rotary actuator that has been developed for operation on Mars. The aim of this actuator is to provide an in-flight calibration system for the Dust Sensor instrument of the MEIGA-MetNet Mission that will perform airborne dust opacity measurements on the Mars surface. The total mass of the actuator is less than 9 grams (without control FPGA). A Qualification Model (QM) and a Flight Model (FM) will be presented in this work. The actuator presented is designed and qualified to withstand an impact inertia up to 2000 g and work at low temperatures (-90 C) under vacuum conditions. Similarly, two versions of a Pin Puller mechanism working in the temperature range -30 C to +125 C have been designed and analyzed. Operative breadboard models of both devices were built and tested. The main characteristics of these devices as well as preliminary operating results will be shown in this work. The use of Shape Memory Alloys on the proposed actuators presents several advantages of lightweight, high force-to-weight ratio, and low volume.

During Phases III and IV of this project it was determined that the physical attributes of the prototypes developed during the earlier work was inappropriate for bridge deck installations. Mn/DOT engineers required that they be planar and not require drainage through the deck. As RWIS platforms had been widely deployed on decks throughout the state, we decided to adhere to the RWIS geometric format. This necessitated a significant re-engineering of the sensor hardware before installation and testing at remote bridge sites could proceed. To that end extensive development of a robust sensor meeting these requirements was developed and tested without compromise to the earlier performance results. In large part the maintenance of performance was achieved through a significant modification of the software to include Wavelet analysis of the raw data in the determination of surface state of the sensor platform (ice vs air vs water vs electrolyte present on the sensing electrode structure). The combined regression results for raw TDR responses treated by three analysis procedures are shown to give rise to very reliable results. Unfortunately, remote field testing of sensors installed on bridge decks was not accomplished.

The Improved Sensor Integration (ISI) project is an effort to cross- cue various force protection and persistent surveillance systems from unattended ground sensor systems and other data sources. The ISI systems communicate primarily through cursor on target messages. The Terra Harvest controller architecture was adopted to integrate the Applied Research Associates Expendable Unattended Ground Sensor (EUGS) system into the ISI project and provides a potential entry point for other types of unattended sensors. This report describes the architecture used to integrate EUGS into the ISI system by way of Terra Harvest and Cursor on Target, and discusses some of the issues and solutions that were identified during the integration.

The Hyperspectral Imager for Coastal Oceans (HICO) was constructed and is managed by the US Naval Research Laboratory (NRL). Pre-launch calibration, and therefore sensor measurement accuracy, of satellite sensors can be affected by launch vibrations, temperature fluctuations, space radiation and other factors. Vicarious correction was applied to HICO imagery to improve measurement accuracy. Vicarious calibration applies a 'reverse' atmospheric correction where satellite-derived atmospheric factors are added to in situ normalized-water-leaving radiances to generate 'vicarious' top-of-atmosphere radiances that are used to compute gain and offset values. The gains and offsets are subsequently applied to satellite sensor top-of-atmosphere radiances to force closer agreement with in situ measurements. In situ data from the Marine Optical Buoy (MOBY) and from some of the NASA AErosol RObotic NET Ocean Color (AEONET-OC) platforms were used to provide in situ water measurements used to vicariously calibrate HICO data.
