Volcanic research is a significant part of the "Earth Surface & Interior" focus area of the NASA Earth Science program. Of particular interest are sensors for measuring the chemical composition and emission rate of gases released by volcanoes, from magma to the atmosphere, both prior to and during eruptions. The vast majority of ground based plume observations concern sulfur dioxide (SO2), the third most abundant volcanic gas. Sulfur dioxide measurements provide valuable information concerning the masses and motions of underground magmas. Vista Photonics proposes an innovative self-calibrating optical technology for sensitive and selective in situ measurement of SO2 in volcanic gas plumes. The self-calibrating feature is intended to maintain the specified performance characteristics under harsh operating conditions. Phase I research will focus on demonstrating the feasibility of the innovative SO2 detector and outline the design of the Phase II prototype instrument. Successful completion of this program will lead to development of an inexpensive, compact, self-contained, lightweight SO2 measurement instrument suitable for use on a variety of ground based and airborne platforms including remotely operated aircraft and surface craft.

Radar technology offers a very flexible, powerful tool for applications such as object detection, tracking, and characterization, as well as remote sensing, imaging, sounding, weather measurement and analysis. Historically, radar systems have tended to be either large, complex, power-hungry, purpose-built systems, or extremely simple systems of limited capability. More recently, miniaturization of high-performance programmable integrated circuit technologies as embodied in field-programmable gate arrays, as well as rapid advances in high-speed data conversion technologies at a gigasample per second and beyond, have enabled the implementation of direct-conversion radio frequency (RF) systems, including radar, that operate almost completely in the digital domain. In addition, solid-state high-power RF device technologies have improved in efficiency and speed to the point where highly efficient pulsed transmit sources are possible. As these device technologies have matured, their application in space environments has accelerated to the point where extremely flexible programmable radar systems can be implemented in a very small size, weight, and power footprint. Trident Systems has developed a powerful radar architecture called RAPTOR, validating it through flight testing on a number of Department of Defense programs; initial analysis has shown the feasibility of transitioning this design to the space environment. Through a comprehensive program of requirements development, trade studies, critical component and design analyses, fault mitigation simulation, and system design, Trident will develop the design for a complete space-qualifiable UHF/L-band radar transceiver in a 96mm x 90mm x 31mm PC-104e form factor that meets all customer mission needs, and is applicable to a wide range of applications (NASA and others). By basing the solution on Trident's proven RAPTOR technology, the system will rapidly achieve a high TRL.

Sensing gas molecules is critical to environmental monitoring, control of chemical processes, space missions as well as agricultural and medical applications. Existing electrical sensor materials are based on semi-conducting metal oxides, silicon devices, organic materials and gas responsive polymers or ceramics. To achieve high chemical sensitivity, semi-conducting metal oxide sensors must be operated at elevated temperatures (200 to 600?C). This need for high temperature operation increases the device complexity and renders them unsuitable for real-time portable applications. On the other hand, conducting polymers and organic semi-conductors are suitable for room temperature operation, but exhibit limited sensitivity. Clearly, there is a need to develop new technology that will allow for operation at room temperature and atmospheric pressure and provide for high-sensitivity measurements and low response times. We have already experimentally demonstrated under our own Internal R&D funding, that carbon nanotubes provide this enabling technology This effort will experimentally demonstrate a new nanotube sensor technology, which is a radical departure from conventional nanotube sensor approaches. Tests already performed with the proposed carbon nanotube sensor indicate that the electrical response of each gas is unique and that the individual gas concentrations can also be determined.

<p> a)&nbsp;&nbsp;&nbsp;&nbsp; Addition of flywheels to space flight exercise hardware in order to simulate free weight inertia increases wear on equipment and has resulted in costly repairs to exercise hardware in space. Ground based exercise studies have shown improved bone density and muscle strength with exercise equipment that use pneumatic resistance forces and have no added inertial forces beyond that derived from the mass of the human body.&nbsp; An exhaustive literature search revealed no direct comparisons between pneumatic resistance exercise devices and weight stack or free weight exercises used to maintain or strengthen bone and muscle. In the absence of a direct comparison, exercise prescriptions and exercise equipment requirements specifying simulation of weight stack type rate dependent variability in forces on the ARED for health maintenance have been based upon opinion. Use of weight stack exercise equipment and flywheels to simulate weight stack characteristics reduces loads below the target level in up to half of the weight lifting cycle, results in poorly controlled rate dependent variability in loads, and can induce injurious peak loads. This variability undermines the exercise requirements for constant load with a high eccentric to concentric load ratio agreed upon by musculoskeletal and exercise scientists who defined ARED requirements for ISS. Numerous studies in the literature show exercise equipment that provides high concentric and eccentric loads improves bone density and muscle strength, with and without transient loads due to mass moment of inertia. Despite low levels of evidence&nbsp; that impact&nbsp; (separate from high sustained loads) is beneficial to bone and muscle, many exercise guidelines continue to state impact is desirable for bone maintenance. Impact is contraindicated in individuals with arthritis and joint injuries. Therefore, use of the ISS ARED to demonstrate that high constant loads without transient loads maintains bone and muscle will be beneficial to NASA in simplifying hardware design and maintenance and will improve exercise safety. Information generated in this proposed activity will be used to support&nbsp; exercise improvements that will enhance durability, safety, and efficiency of exercise hardware for space flight.</p>

Energid Technologies proposes a software tool to predict robotic mission performance and support supervision of robotic missions even when environments and situations are profoundly unknown. It transcends common Monte Carlo simulations by supporting input parameters for which probability distributions are not available. Stochastic optimization is combined with randomized simulation to bound statistical measures of performance and convey the parameters giving the extreme scenarios. It also provides 3D immersive presentation of those scenarios. The act of performing multiple simulation runs in real time is enabled by the fast simulation capability provided by Energid Technologies' existing software combined with the development of new algorithms and software. The new algorithms cover path planning, scene rendering, sensor modeling, and robot-terrain interaction modeling. In the new software, automatic path planning is calculated using a combination of static and dynamic techniques. Scene rendering for sensor modeling is implemented using fast ray tracing for low-update-rate sensors and ray-tracing-validated rasterization for fast-update-rate sensors. Robot-terrain interaction is calculated through particle simulations implemented on graphics cards. For maximum performance, the new software allows distribution of randomized simulation runs over multiple networked PCs and cloud-based clusters. This combination of fast algorithms and statistical optimization offers a tool that provides new engineering insights and data. The software will be demonstrated on the example mission of searching for ice near near the southern lunar pole, giving evidence of the ability of the tool to support challenging relevant missions.

Description
This data set contains catch (landed catch) and effort for fishing trips made by vessels that have been issued a Federal permit for the Gulf of Mexico reef fish, South Atlantic snapper-grouper, sharks, and king and Spanish mackerel fisheries. Because the soak time for these fisheries is relatively short, it is infeasible to require fishermen to complete a separate form every time the gear is deployed. Thus, the catch and effort data for the entire trip are reported on a single form (i.e., one form per trip). In 1990, the Southeast Fisheries Science Center (SEFSC) initiated a logbook program for vessels that held a federal vessel permit to fish in the Gulf reef fish fishery. A similar program was initiated in 1992 for vessels with federal permits in the snapper-grouper fishery in the South Atlantic region. These two programs combined to form the basis of the coastal fisheries logbook program. In 1993, this program was expanded to include vessels with federal permits in the shark fishery and in 1999 it was expanded to include vessels with commercial vessel permits in the king and Spanish mackerel fisheries. The types of information required on this trip form includes information on the quantity (reported in pounds) caught for each species, the area of catch, the type and quantity of gear, the date of departure and return, the dealer and location (county and state where the trip is unloaded), the duration of the trip (time away from dock), an estimate of the fishing time, and the number of crew are included on this form.
