A Combined Model-Based and Data-Driven Prognostic Approach for Aircraft System Life Management

Failure prognosis - as a natural extension to the fault detection and isolation (FDI) problem - has become a key issue in a world where the economic impact of system reliability and cost-effective operation of critical assets is steadily increasing. Failure prognostic algorithms aim to characterize the evolution of incipient fault conditions in complex dynamic processes, thus allowing to estimate of the remaining useful life (RUL) of subsystems and components. Several examples can be used here to illustrate the range of possible applications for these algorithms: electro-mechanical systems, continuous-time manufacturing processes, structural damage analysis, and even fault tolerant
software architectures. Most of them have in common the fact that they are highly complex, nonlinear, and affected by large-grain uncertainty.

We introduce in this chapter an integrated failure prognosis architecture that is applicable to a variety of aircraft systems and industrial processes. We are targeting a specific rotorcraft system as a prototypical testbed for proof-of-concept. The overall architecture consists of an on-board and an off-board module for eventual on-platformimplementation purposes.

GO A PWS RESAMP SUMMARY GASPRA SPECTRUM ANALYZER 60S V1.0

This data set includes 1-minute averages of the electric and magnetic wave spectra obtained during the period that the Galileo plasma wave receiver was operated during the electric field spectrum is the electric field spectral density in units of V^2/m^2/Hz. The magnetic field spectrum is provided in units of magnetic field spectral density, nT^2/Hz.  The spectral information is averaged and binned into 49 logarithmically-spaced channels from about 6 Hz to 5.6 MHz for the electric measurements and 34 channels from about 6 Hz to 75 kHz for the magnetic.  Note that these 'channels' do not generally correspond to the 158 specific channels described in the instrument description document. The reduction in spectral resolution for this data set was performed in order to make the set more conducive to use as a browse data set.   The sources of this browse data set are the High Frequency Receiver, Sweep Frequency Receiver, and Spectrum Analyzer which make up the Low Rate Science portion of the PWS.

DAWN GRAND MAP VESTA NEUTRON            
                                     ABSORPTION V1.0

A global map of a unitless               compositional parameter, delta-C_perpendicular (DCP), and propagated    1-sigma uncertainties is provided.  DCP varies linearly with the        macroscopic thermal neutron absorption cross section of Vesta's         regolith.  An equation for converting tabulated DCP values to           absorption units is provided in this document. DCP was determined from  thermal and epithermal neutron counting rates measured by the NASA      Dawn mission's Gamma Ray and Neutron Detector (GRaND) while in low      altitude mapping orbit, about 210 km from Vesta's surface.  The         measurements are representative of Vesta's bulk regolith composition    to depths of a few decimeters with a spatial resolution of about        300-km full-width-at-half-maximum of arc length on the surface.  The    methods used to determine neutron absorption are described by           PRETTYMANETAL2013.

Transcription profiling of Drosophila exposed to a levitation magnet for different lengths of time

Drosophila samples were exposed to the levitation magnet inside a 25mm diameter tubes with 3 ml of yeast-based Drosophila food in the bottom and a chamber of only 5 mm of height over the food. This small region is needed in order to guarantee that all the flies were located in the effective g area so a maximum of 35 to 40 imagos or pupa can be exposed to each condition per experiment. All experiments were carried out with a parallel 1g external control in a temperature regulated incubator outside the magnet. Three experiments of different duration were performed inside the magnet system to analyze the effect of strong magnetic fields and magnetic levitation during different stages of the Drosophila development

RNAseq analysis of the response of Arabidopsis thaliana to fractional gravity under blue-light stimulation during spaceflight

Traveling to nearby extraterrestrial objects having a reduced gravity level (partial gravity) compared to Earth's gravity is becoming a realistic objective for space agencies. The use of plants as part of life support systems will require a better understanding of the interactions among plant growth responses including tropisms, under partial gravity conditions. Here, we present results from our latest space experiments on the ISS, in which seeds of Arabidopsis thaliana were germinated, and seedlings grew for six days under different gravity levels, namely micro-g, several intermediate partial-g levels, and 1g, and were subjected to irradiation with blue light for the last 48 hours. RNA was extracted from 20 samples for subsequent RNAseq analysis. Transcriptomic analysis was performed using the HISAT2-Stringtie-DESeq pipeline. Differentially expressed genes were further characterized for global responses using the GEDI tool, gene networks and for Gene Ontology (GO) enrichment.

Gravitational signature of synchronized cell cultures in particular cell cycle stages

Cell cycle and cell proliferation are decoupled under altered gravity conditions. We have previously shown that semisolid cell cultures of Arabidopsis suffer overall genome changes in response to altered gravity and also that cell cycle stages duration is altered. By using synchronized cell cultures we will demonstrate the precise alterations in cell cycle duration and also the transcriptional signature in any of them. - Experiments consists on exposures of Arabidopsis cell cultures to 1g control/simulated microgravity (RPM) conditions. Asynchronous cells exposed for 14 h + Syncronous populations choosen to have an enrichment of cell cycle phases were used (being T7/T10 samples on G2 phase T14/T16 samples on G1 phase). 6 dye-swap - time course,treated vs untreated comparison

Gene expression profiling of PBL in response to ionising radiation and modeled microgravity

BACKGROUND: Ionizing radiation (IR) can be extremely harmful for human cells since an improper DNA-damage response (DDR) to IR can contribute to carcinogenesis initiation. Perturbations in DDR pathway can originate from alteration in the functionality of the microRNA-mediated gene regulation being microRNAs (miRNAs) small noncoding RNA that act as post-transcriptional regulators of gene expression. In this study we gained insight into the role of miRNAs in the regulation of DDR to IR under microgravity a condition of weightlessness experienced by astronauts during space missions which could have a synergistic action on cells increasing the risk of radiation exposure. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed miRNA expression profile of human peripheral blood lymphocytes (PBL) incubated for 4 and 24 h in normal gravity (1 g) and in modeled microgravity (MMG) during the repair time after irradiation with 0.2 and 2Gy of gamma-rays. Our results show that MMG alters miRNA expression signature of irradiated PBL by decreasing the number of radio-responsive miRNAs. Moreover let-7i* miR-7 miR-7-1* miR-27a miR-144 miR-200a miR-598 miR-650 are deregulated by the combined action of radiation and MMG. Integrated analyses of miRNA and mRNA expression profiles carried out on PBL of the same donors identified significant miRNA-mRNA anti-correlations of DDR pathway. Gene Ontology analysis reports that the biological category of Response to DNA damage is enriched when PBL are incubated in 1 g but not in MMG. Moreover some anti-correlated genes of p53-pathway show a different expression level between 1 g and MMG. Functional validation assays using luciferase reporter constructs confirmed miRNA-mRNA interactions derived from target prediction analyses. CONCLUSIONS/SIGNIFICANCE: On the whole by integrating the transcriptome and microRNome we provide evidence that modeled microgravity can affects the DNA-damage response to IR in human PBL. Overall Design: Gene expression signature was defined in PBL irradiated with gamma-rays (2.0 Gy) and incubated in modeled microgravity (mmg) and in parallel ground conditions (1g) for 24h. Five independent experiments were performed for each donor to address which mRNAs were regulated on IR stress. The level of each transcript was represented as Log2.

Land Surface Reflectance - L4-5

The surface reflectance CDR is generated from specialized software called Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS). LEDAPS was originally developed through a National Aeronautics and Space Administration (NASA) Making Earth System Data Records for Use in Research Environments (MEaSUREs)grant by NASA Goddard Space Flight Center (GSFC) and the University of Maryland (Masek et al., 2006). The software applies Moderate Resolution Imaging spectroradiometer (MODIS) atmospheric correction routines to Level-1 Landsat Thematic Mapper (TM) or Enhanced Thematic Mapper Plus (ETM+)data.  Water,vapor, ozone, geopotential height, aerosol optical thickness,and digital elevation are input with Landsat data to the Second Simulation of a Satellite Signal in the Solar Spectrum (6S) radiative transfer models to generate top of atmosphere (TOA)reflectance, surface reflectance, brightness temperature, and masks for clouds, cloud shadows, adjacent clouds, land, and water.  The result is delivered as the Landsat surface reflectance CDR.

Detection and Prognostics on Low Dimensional Systems

This paper describes the application of known and novel prognostic algorithms on systems that can be described by low dimensional, potentially nonlinear dynamics. The methods rely on estimating the conditional probability distribution of the output of the system at a future time given knowledge of the current state of the system. We show how to estimate these conditional probabilities using a variety of techniques, including bagged neural networks and kernel methods such as Gaussian Process Regression (GPR). The results are compared with standard method such as the nearest neighbor algorithm. We demonstrate the algorithms on a real-world data set and a simulated data set. The real-world data set consists of the intensity of an NH3 laser. The laser data set has been shown by other authors to exhibit low-dimensional chaos with sudden drops in intensity. The simulated data set is generated from the Lorenz attractor and has known statistical characteristics. On these data sets, we show the evolution of the estimated conditional probability distribution, the way it can act as a prognostic signal, and its use as an early warning system. We also review a novel approach to perform Gaussian Process Regression with large numbers of data points.
