Application of Inductive Monitoring System to Plug Load Anomaly Detection

NASA Ames Research Center’s Sustainability Base is a new
50,000 sq. ft. LEED Platinum office building. Plug loads
are expected to account for a significant portion of the overall
energy consumption. This is because building design choices
have resulted in greatly reduced energy demand from Heating,
Ventilation, and Air Conditioning (HVAC) and lighting
systems, which are major contributors to energy consumption
in traditional buildings. In anticipation of the importance of
plug loads in Sustainability Base, a pilot study was conducted
to collect data from a variety of plug loads. A number of cases
of anomalous or unhealthy behavior were observed including
schedule-based rule failures, time-to-standby errors, changed
loads, and inter-channel anomalies. These issues prevent effective
plug load management; therefore, they are important
to promptly identify and correct. The Inductive Monitoring
System (IMS) data mining algorithm was chosen to identify
errors. This paper details how an automated data analysis program
was created, tested and implemented using IMS. This
program will be applied to Sustainability Base to maintain
effective plug load management system performance, identify
malfunctioning equipment, and reduce building energy
consumption.

RTO-TR-26

Computational Unsteady Aerodynamics computer codes are being increasingly used. In order to
validate their results they must be tested against valid experimental data. The present report aims at
collecting reliable experimental data on unsteady aerodynamics and presenting them in a form
which permits use for verification of codes. For ease of handling, the data are also presented in
machine readable form (CD-ROM). Data on increasingly complex generic forms were selected and
the following categories are covered: flutter, buffet, stability and control, dynamic stall, cavity
flows, store separation. Computational solutions are included in order to permit evaluation of codes
and analysis of solutions which differ from experimental data.

GPM GROUND VALIDATION NASA MICRO RAIN RADAR (MRR) GCPEX V2

The GPM Ground Validation NASA Micro Rain Radar (MRR) GCPEx dataset was collected by a Micro Rain Radar (MRR), which is a vertically pointing Doppler radar which provides measurements of vertical velocity, drop size distribution, rainfall rate, attenuation, liquid water content, and reflectivity factor obtained during the GPM Cold-season Precipitation Experiment (GCPEx), which took place in Canada during Winter 2011-2012. GCPEx addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. The MRR is a frequency-modulated continuous wave (FMCW) vertically pointing Doppler radar, which operates at 24.24GHz, and it is the second generation of the instrument manufactured by METEK (http://metek.de/product/mrr-2/). NASA MRR data was collected from late October 2011 through March 2013. Version 2 of the dataset became active on 13-May-2015.

An Approach to Prognostic Decision Making in the Aerospace Domain

The field of Prognostic Health Management (PHM) has been undergoing rapid growth in recent years, with development of increasingly sophisticated techniques for diagnosing faults in system components and estimating fault progression tra- jectories. Research efforts on how to utilize prognostic health information (e.g. for extending the remaining useful life of the system, increasing safety, or maximizing operational ef- fectiveness) are mostly in their early stages, however. This process of using prognostic information to determine a sys- tem’s actions or its configuration is beginning to be referred to as Prognostic Decision Making (PDM). In this paper we, first, propose a formulation of the PDM problem with the at- tributes of the aerospace domain in mind, outline some of the key requirements on PDM methods, and explore techniques that can be used as a foundation of PDM development. The problem of Pareto set viability, i.e. satisfaction of perfor- mance goals set for objective functions, is discussed next, followed by ideas for possible solutions. The ideas, termed Dynamic Constraint Redesign (DCR), have roots in the fields of Multidisciplinary Design Optimization and Game Theory. Prototype PDM and DCR algorithms are also described and results of their testing are presented.

Superconducting Resonator Spectrometer for Millimeter- and Submillimeter-Wave Astrophysics Project

"We propose to develop a novel ultra-compact spectrograph-on-a-chip for the submillimeter and millimeter waveband. SuperSpec uses planar lithographed superconducting transmission-line filters to sort incident radiation by frequency to an array of direct detectors such as MKIDs. The system is naturally wideband and can be very low loss, enabling background-limited spectroscopy on the ground and in space, as is currently done with a diffraction grating spectrographs. But while moderate-resolution grating systems for the mm and submm bands have sizes measured in tens of centimeters, SuperSpec can have a size measured in millimeters. If successful, SuperSpec will pave the way for a new kind of astronomical instrument for the submm/mm: a 2-D array of hundreds to thousands of individual spectrometers, each simultaneously measuring a separate spectrum. With the possible exception of polarization, such an instrument extracts all available information from the light at a telescope focal plane.



SuperSpec thus offers the potential to revolutionize astrophysics in the far-IR through millimeter, an important spectral regime for which the the Astro2010 Decadal Survey made two specific recommendations for this decade: 1) Participate in the Japanese-led SPICA space telescope with a spectrometer instrument such as BLISS, and 2) Construct CCAT and its associated instrumentation. Depending on SPICA's schedule, SuperSpec technology could be injected and would enhance and extend the long-wavelength capability of BLISS or a similar instrument. Whether or not SPICA moves ahead quickly, our demonstration will position SuperSpec to be used in on CCAT and suborbital platforms this decade, paving the way for optimal science return with future NASA-led cryogenic far-IR space missions on the drawing board for the next decade: CALISTO/SAFIR and SPIRIT.



SuperSpec is based on propagation on a superconducting transmission line (TL). As radiation propagates along the line, it encounters a seri

JPSS-2 CrIS IMG_COL: Array indices for collocated VIIRS observations V3.0 (SNDRJ2CrISL1BIMGC) at GES DISC

The Cross-track Infrared Sounder (CrIS) Level 1B Full Spectral Resolution (FSR) data files contain radiance measurements along with ancillary spacecraft, instrument, and geolocation data of the CrIS instrument on the Joint Polar Satellite System-2 (JPSS-2) platform. This platform is also know as NOAA-21 (National Oceanic and Atmospheric Administration). 

The IMG product supplements the CrIS Level 1B (L1B) hyperspectral radiance product by providing collocated high-spatial resolution data from the Visible Infrared Imaging Radiometer Suite (VIIRS) imager located on the same platform. VIIRS radiance and cloud mask values are grouped and aggregated for every CrIS field of view (FOV) and made available in a format intended for use alongside the CrIS L1B data. The collocated VIIRS level 1 / cloud mask statistical summary (collection name SNDRJ2CrISL1BIMG) is the main product and consists of collocated CrIS field of views with the VIIRS cloud mask and radiances/reflectances. This can be thought of as a match-up between CrIS and VIIRS. The supplementary product, array indices for collocated VIIRS observations (SNDRJ2CrISL1BIMGC), product additionally makes available CrIS and VIIRS data array index values that result from the collocation process that is performed as part of producing IMG. These index values can be leveraged by end users to further augment CrIS data by extracting collocated observations from any additional VIIRS data products that aren’t already present in IMG.

The FSR files have 2,223 channels (*2211 apodized channels): 637 (*633) shortwave channels from 3.9 to 4.7 microns (2555 to 2150 cm-1), 869 (*865) midwave channels from 5.7 to 8.05 microns (1752.5 to 1242.5 cm-1), and 717 (*713)longwave channels from 9.1 to 15.41 microns (1096.25 to 648.75 cm-1). Each CrIS field-of-regard (FOR) contains 9 field-of-views (FOVs) arranged in a 3X3 array. The Level 1B files contain 30 FORs in the cross track direction and 45 in the along track direction. Data products are constructed on six minute boundaries.

The Visible Infrared Imaging Radiometer Suite (VIIRS) has 22 imaging and radiometric bands covering wavelengths from 0.41 to 12.5 microns. It provides the sensor data records for clouds, sea surface temperature, ocean color, and others. This IMG_COL product contains the colocation indices of the VIIRS pixels within each CrIS footprint.

Probabilistic Fault Diagnosis in Electrical Power Systems

Electrical power systems play a critical role in spacecraft and aircraft. This paper discusses our development of a diagnostic capability for an electrical power system testbed, ADAPT, using probabilistic techniques. In the context of ADAPT, we present two challenges, regarding modelling and real-time performance, often encountered in real-world diagnostic applications. To meet the modelling challenge, we discuss our novel high-level specification language which supports auto-generation of Bayesian networks. To meet the real-time challenge, we compile Bayesian networks into arithmetic circuits.  Arithmetic circuits typically have small footprints and are optimized for the real-time avionics systems found in spacecraft and aircraft. Using our approach, we present how Bayesian networks with over 400 nodes are auto-generated and then compiled into arithmetic circuits. Using real-world data from ADAPT as well as simulated data, we obtain average inference times smaller than one millisecond when computing diagnostic queries using arithmetic circuits that model our real-world electrical power system.

Plume Mitigation for Mars Terminal Landing: Soil Stabilization Project

&lt;p&gt;A sustained human presence on the Moon,&amp;nbsp;Mars, or other celestial bodies, will require&amp;nbsp;numerous disciplines to create technologies,&amp;nbsp;solve current known problems, and anticipate&amp;nbsp;new ones. One problem identified during the&amp;nbsp;Apollo missions is plume ejecta: the expulsion of&amp;nbsp;dust, regolith, or other loose material from&amp;nbsp;the force of launch or landing.&amp;nbsp; Rocket plume effects on Mars will be&amp;nbsp;different from those on the Moon. Because Mars has an atmosphere, ejected particles will&amp;nbsp;not travel as far, meaning that infrastructure&amp;nbsp;could be placed at a safe distance from the&amp;nbsp;launch pad and not receive blast effects.&amp;nbsp;However, the presence of an atmosphere will&amp;nbsp;cause the rocket exhaust to collimate, which&amp;nbsp;will probably produce much deeper craters&amp;nbsp;than the Apollo missions produced on the&amp;nbsp;Moon.&amp;nbsp;&lt;/p&gt;&lt;p&gt;Plume ejecta was observed and&amp;nbsp;photographed during the recent landing of&amp;nbsp;the Mars rover, Curiosity. Even though the&amp;nbsp;sky crane landing system was designed to&amp;nbsp;minimize plume effects on the Mars surface,&amp;nbsp;areas of surface erosion were observed after&amp;nbsp;landing. Curiosity is the largest&amp;nbsp;vehicle that has landed on Mars. A human-sized&amp;nbsp;lander will be considerably larger, will&amp;nbsp;have more powerful rockets, and therefore,&amp;nbsp;will probably disturb the surface soil much&amp;nbsp;more. Deploying a landing pad or stabilizing&amp;nbsp;the soil can mitigate this problem.&lt;/p&gt;&lt;p&gt;The goal of this project was to develop technology for building a landing pad through the following tasks:&lt;/p&gt;&lt;ol&gt;&lt;li&gt;Demonstrate microwave sintering under Mars like conditions.&lt;/li&gt;&lt;li&gt;Investigate surface stabilization methods used for terrestrial applications and develop recommendations for a Mars landing pad based on these methods.&lt;/li&gt;&lt;li&gt;Develop a plan for implementing a microwave sintering system on a mobile rover.&lt;/li&gt;&lt;/ol&gt;&lt;p&gt;The project was completed successfully, achieving the first ever sintering of a Mars simulant under Mars like conditions.&amp;nbsp; In addition, a design for a rover mounted sintering system was created.&amp;nbsp; Recommendations for initial soil measurements were developed based of off terrestrial experience.&lt;/p&gt;
