Vehicle-Level Reasoning Systems:  Integrating System-Wide data to Estimate Instantaneous Health State

One of the primary goals of Integrated Vehicle Health Management (IVHM) is to detect, diagnose, predict, and mitigate adverse events during the flight of an aircraft, regardless of the subsystem(s) from which the adverse event arises. To properly address this problem, it is critical to develop technologies that can integrate large, heterogeneous (meaning that they contain both continuous and discrete signals), asynchronous data streams from multiple subsystems in order to detect a potential adverse event, diagnose its cause, predict the effect of that event on the remaining useful life of the vehicle, and then take appropriate steps to mitigate the event if warranted. These data streams may have highly non-Gaussian distributions and can also contain discrete signals such as caution and warning messages which exhibit non-stationary and obey arbitrary noise models. At the aircraft level, a Vehicle-Level Reasoning System (VLRS) can be developed to provide aircraft with at least two significant capabilities:  improvement of aircraft safety due to enhanced monitoring and reasoning about the aircraft’s health state, and also potential cost savings through Condition Based Maintenance (CBM).  Along with the achieving the benefits of CBM, an important challenge facing aviation safety today is safeguarding against system- and component-level failures and malfunctions.

Impact of Input Uncertainty on Failure Prognostic Algorithms: Extending the Remaining Useful Life of Nonlinear Systems

This paper presents a novel set of uncertainty measures to quantify the impact of input uncertainty on nonlinear prognosis systems. A Particle Filtering-based method is also presented that uses this set of uncertainty measures to quantify, in real time, the impact of load, environmen- tal, and other stresses for long-term prediction. Further- more, this work shows how these measures can be used to implement a novel feedback correction loop aimed to suggest modifications, at a system input level, with the purpose of extending the remaining useful life of a faulty nonlinear, non-Gaussian system. The correction scheme is tested and illustrated using real vibration feature data from a fatigue-driven fault in a critical aircraft compo- nent.

Wave Measurements taken NW of Culebra Island, Puerto Rico, 2023

Wave and sea surface temperature measurements collected by a Sofar Spotter buoy in 2023. The buoy was deployed on July 27, 2023 at 11:30 UTC northwest of Culebra Island, Puerto Rico, (18.3878 N, 65.3899 W) and recovered on Nov 5, 2023 at 12:45 UTC. 

Data are saved here in netCDF format, organized by month, and include directional wave statistics, GPS, and SST measurements at 30-minute intervals. Figures produced from these data are provided here as well. They include timeseries of wave height/period/direction and SST, GPS location, wave roses, and directional spectra. Additionally, raw CSV files from the Spotter's memory card can also be found below.

NetCDF files can be read in python using the netCDF4 or Xarray packages, or through MATLAB using the "ncread()" command.

Arkin and Janowiak GPI: IR -Based Monthly Rainfall for the GPCP 2.5 x 2.5 degree V1 (RAIN_ARKIN) at GES DISC

These data are transitioned to a state of permanent preservation. They are available upon request.
More advanced datasets have been developed since. 
One recommended replacement is the GPCP (doi: 10.5067/DBVUO4KQHXTK) product developed under the MEaSUREs project. 

The Arkin and Janowiak GPI (GOES Precipitation Index)  was the infrared-based monthly rainfall  estimate produced by the early GPCP (Global Precipitation Climatology Project) algorithms. The infrared observations  from geostationary satellites (GOES, GMS, Meteosat) are used to produce these monthly mean rainfall totals on a 2.5 deg by 2.5 deg grid from 40 N to 40 S for the period Jan 1986 to Dec 1995.

Battery Health Management System for Electric UAVs

In summary, this paper lays out a novel battery health management technique for application onboard an electric UAV. This technique is also applicable to other electric vehicles, like electric cars. Electric cars are not new; they were more popular and reliable at the turn of the twentieth century as compared to their gasoline powered rivals. However, the uncertainty in determining battery life plagued electric vehicles then as it does now. A recent report by the Consumer Electronics Association, ―Electric Vehicles: The Future of Driving‖, indicates that although these vehicles are increasing in popularity, running out of battery power on the road is the top concern for consumers (71% of adults surveyed). Thus developing advanced battery health management techniques is very important. the RUL pdf. This is turn can motivate and inform mission replanning activity. The PF prognostic framework can also be used to evaluate the effectiveness of possible mitigation actions, thus improving operational safety and optimizing battery power.

Physical Sciences Informatics (PSI) System data repository- International Space Station (ISS)

NASA’s Physical Sciences Research Program, along with its predecessors, has conducted significant fundamental and applied research in the physical sciences.  The International Space Station (ISS) is an orbiting laboratory that provides an ideal facility to conduct long-duration experiments in reduced gravity and allows continuous and interactive research similar to Earth-based laboratories.  This enables scientists to pursue innovations and discoveries not currently achievable by other means.  NASA’s Physical Sciences Research Program also benefits from collaborations with several of the ISS International Partners—Europe, Russia, Japan, and Canada—foreign governments with space programs, such as France, Germany, and Italy.

Terra MODIS Level-Regional Regional 11µm Day/Night Sea Surface Temperature (SST) Data, version R2019.0

MODIS (or Moderate-Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.

EnviroAtlas - Los Angeles, CA - Domestic Water Demand per Day by U.S. Census Block Group

As included in this EnviroAtlas dataset, community level domestic water demand is calculated using locally available water use data per capita in gallons of water per day (GPD), distributed dasymetrically, and summarized by Census block group. Domestic water use, as defined in this case, is intended to represent residential indoor and outdoor water use (e.g., cooking, hygiene, landscaping, pools, etc.) for primary residences (i.e., excluding second homes and tourism rentals). For the purposes of this metric, these publicly-supplied estimates are also applied and considered representative of local self-supplied water use. Specific to Los Angeles, CA, Urban Water Management Plans (available via data.ca.gov and individual providers) and an average of available Residential Gallons Per Capita per Day (R-GPCD) data (available through the California State Water Resources Control Board (CSWRCB)) were used. Within the EnviroAtlas community boundary, provider estimates range from 42 to 255 GPD.

SAL and PVS Model of TTEthernet Synchronization Protocol

Timed-Triggered Ethernet (or TTEthernet)is a communication infrastructure that enables the use of Ethernet in real-time, distributed systems. TTEthernet is compatible with traditional IEEE 802.3 switched Ethernet standards, and is designed to support dataflows of mixed criticality on a single network. For traffic of the highest criticality, TTEthernet provides a timed-triggered communication service that relies on a fault-tolerant clock-synchronization protocol.

We have developed formal models of parts of the TTEthernet protocols and analyzed safety-critical properties using both SAL and PVS. Related work by Wilfried Steiner is described in the SAL Wiki.
