Developing IVHM Requirements for Aerospace Systems

The term Integrated Vehicle Health Management (IVHM) describes a set of capabilities that enable sustainable and safe operation of components and subsystems within aerospace platforms. However, very little guidance exists for the systems engineering aspects of design with IVHM in mind. It is probably because of this that designers have to use knowledge picked up exclusively by experience rather than by established process. This motivated a group of leading IVHM practitioners within the aerospace industry under the aegis of SAE’s HM-1 technical committee to author a document that hopes to give working engineers and program managers clear guidance on all the elements of IVHM that they need to consider before designing a system. This proposed recommended practice (ARP6883 [1]) will describe all the steps of requirements generation and management as it applies to IVHM systems, and demonstrate these with a “real-world” example related to designing a landing gear system. The team hopes that this paper and presentation will help start a dialog with the larger aerospace community and that the feedback can be used to improve the ARP and subsequently the practice of IVHM from a systems engineering point-of-view.

Automated External Defibrillator

<div style='text-align:Left;'><div><div><p><span>An AED is an electronic device that analyzes the heart’s rhythm and tells the user to deliver a defibrillation shock when it is required. An AED is portable and easy to use. Anyone who has successfully completed a nationally-recognized CPR/AED course can use an AED. The AED program will train the public to recognize early warning signs of cardiac arrest, perform cardio-pulmonary resuscitation (CPR), and promote the placement of AEDs in places where people work, exercise, and congregate. DC Fire/EMS partners in this effort are the American Heart Association, the DC Chamber of Commerce, the National Capital Chapter of the American Red Cross and Medtronic Physio-Control. Together we are promoting healthy eating and proper exercise, public education programs encouraging people to learn CPR and how to operate an AED, and increasing the availability of AEDs in the District.

National Emissions Inventory (NEI), County-Level, US, 2008, 2011, 2014, EPA OAR, OAPQS

This US EPA Office of Air and Radiation, Office of Air Quality Planning and Standards, Air Quality Assessment Division, Air Quality Analysis Group (OAR, OAQPS, AQAD, AQAG) web service contains the following layers created from the 2008, 2011 and 2014 National Emissions Inventory (NEI): Carbon Monoxide (CO), Lead, Ammonia (NH3), Nitrogen Oxides (NOx), Particulate Matter 10 (PM10), Particulate Matter 2.5 (PM2.5), Sulfur Dioxide (SO2), Volatile Organic Compounds (VOC). Each of these layers conatin county level emissions for 2008, 2011, and 2014. Layers are drawn at all scales. The National Emission Inventory (NEI) is a comprehensive and detailed estimate of air emissions of criteria pollutants, criteria precursors, and hazardous air pollutants from air emissions sources. The NEI is released every three years based primarily upon data provided by State, Local, and Tribal air agencies for sources in their jurisdictions and supplemented by data developed by the US EPA. The NEI is built using the Emissions Inventory System (EIS) first to collect the data from State, Local, and Tribal air agencies and then to blend that data with other data sources. NEI point sources include emissions estimates for larger sources that are located at a fixed, stationary location. Point sources in the NEI include large industrial facilities and electric power plants, airports, and smaller industrial, non-industrial and commercial facilities. A small number of portable sources such as some asphalt or rock crushing operations are also included. Some states voluntarily also provide facilities such as dry cleaners, gas stations, and livestock facilities, which are otherwise included in the NEI as nonpoint sources. The emissions potential of each facility determines whether that facility should be reported as a point source, according to emissions thresholds set in the Air Emissions Reporting Rule (AERR). NEI Point Sources are all included in the EIS Point Data Category. NEI nonpoint sources include emissions estimates for sources which individually are too small in magnitude to report as point sources. These emissions sources are included in the NEI as a county total or tribal total (for participating tribes). Examples include residential heating, commercial combustion, asphalt paving, and commercial and consumer solvent use. NEI nonpoint sources are all included in the EIS Nonpoint Data Category.

Lead Paint Certifications

The Philadelphia Lead Paint Disclosure and Certification Law requires owners of property built before 1978 to provide a certification that a property is lead free or lead safe before it may be rented to a tenant (either a new or renewed lease, formal or informal). This certification (or statement of exemption) must be submitted to the Lead and Healthy Homes Program through the [Lead Certification Submission System](https://leadcertification.phila.gov/login) a requirement to obtain a rental license. This dataset provides the current certification status of each property in the city by OPA account number, based on the information submitted to the Lead and Healthy Homes Program. Note that the certification information must be consistent with the details of the rental license in order for the rental license to be granted.

Fairbanks Large Building VI Data Set

Passive and active VOC measurements were collected weekly for 15 months between December 2020 and April 2022 at the Fairbanks, AZ site. Various indicators and tracers (I&T), including indoor radon, differential pressure, temperature, and other environmental factors, were also collected. Results from this study help clarify the factors that influence temporal trends in VOC concentrations across multiple sampling zones in commercial buildings in a subarctic climate zone and thus inform vapor intrusion sampling strategies.

Convex Hulls for Species Richness and Individual Species

These are .tiff files, with bands for total distance to the convex hull (Distance), as well as individual distances for the 5 dimensions of pH (pH), precipitation (Precipitation), temperature (Temperature), nitrogen deposition (Nitrogen), and sulfur deposition (Sulfur). Note that for open and closed canopy convex hulls, sulfur was not included in the original analysis (Simkin et al. 2016) and thus are not included in the convex hulls. The units for all distances are in standard deviations (based on Mahalanobis distance). Distances are unitless and based on Mahalanobis distance. This dataset is not publicly accessible because: The files are too big for Science Hub (15.9 GB). It can be accessed through the following means: Email Christopher Clark (clark.christopher@epa.gov) for access to the data. Format: The data are .tif files for convex hulls for richness (2 convex hulls, open and closed canopy communities) and species (198 convex hulls).

City Council Legislation: Bills and Local Laws

This dataset contains information on New York City bills from <strong>1998 through 2024</strong>.</br>
The <strong>New York City Council</strong> is the City’s legislative body, responsible for proposing, debating, and voting on legislation that affects all aspects of city governance. The legislative process for Introductions in NYC follows these steps:
<ul>
<strong>Bill Introduced</strong> – A bill is introduced by a Council Member and assigned a number.</br>
<strong>Committee Hearings</strong> – The bill is referred to a committee for review, where public hearings may be held for discussion, public comment, and stakeholder engagement.</br>
<strong>Committee Vote</strong> – The committee votes on whether to advance the bill to the full Council.</br>
<strong>Full Council Vote</strong> – If approved by the committee, the bill is voted on by the entire Council. A majority vote is required for passage.</br>
<strong>Mayoral Action</strong> – Once passed by the Council, the bill is sent to the Mayor, who may sign it into law, veto it, or allow it to become law without a signature. If vetoed, the Council can override the veto with a two-thirds majority vote.</br>
<strong>Enactment</strong> – Once signed or passed via override, the bill is assigned a local law number and becomes part of the city’s legal code. Bills may be enacted immediately, or upon a date defined in the bill.
</ul>
This dataset provides information on all introductions, regardless of whether they were enacted.
