Estimating the Likelihood of Wireless Coexistence Using Logistic Regression: Emphasis on Medical Devices - IEEE Journals & Magazine
Mohamad Omar Al Kalaa ; Seth J. Seidman ; Hazem H. Refai
Medical device manufacturers incorporate wireless technology in their designs to offer convenience and agility to both patients and caregivers. However, the use of unlicensed radio spectrum bands by both medical devices and other equipment raises concerns about wireless coexistence. Work by the accredited standards committee C63 of the American National Standards Institute (ANSI) to provide the community with a consensus standard for coexistence evaluation resulted in the publication of the ANSI C63.27 standard, which was later recognized by the U.S. Food and Drug Administration. Estimating the likelihood of wireless coexistence of a system under test (SUT) in a given environment is central to the evaluation and reporting of wireless coexistence, as made clear in the C63.27 standard. However, no method to perform this estimation is provided. In this paper, we propose the use of logistic regression (LR) to estimate the likelihood of wireless coexistence of a medical device in its intended environment. Radiated open environment coexistence testing was used to realize a test scenario in which the interfering network was IEEE 802.11n Wi-Fi and the SUT was ZigBee; exemplary wireless technologies for interfering network and medical device, respectively. LR model fitting was then performed to derive a model that describes the performance of SUT under a range of wireless coexistence phenomena. Finally, results were incorporated with the outcome of a spectrum survey using Monte Carlo simulation to estimate the SUT likelihood of wireless coexistence in a hospital environment.

Lightfoot calls for enlightened approach to risk management at NASA - SpaceNews.com April 2018
"In his last major speech as NASA’s acting administrator before retiring, Robert Lightfoot said he believes the space agency needs to do a better job assessing risks and making decisions in order to carry out its exploration plans"

"One problem, he said, is that missions are often sold on their benefits, but once under development, the focus shifts to their risks."

He also said that decisions are slowed down because information on various options and their risks isn’t brought fast enough to key officials. “The elevation of risk to senior leadership doesn’t happen fast enough,” he said. “That processes crushes decision velocity.”

Report: “Taking the Pulse of Hacking: A Risk Basis for Security Research” | Center for Democracy & Technology
Via Blake Reid

"Over the past three decades, the community that investigates vulnerabilities in computers and networks – the computer and information security research community – has grown. Beginning as a hobby of early computer scientists such as Cliff Stoll, the security research community has become a well-defined industry element that seeks to help defend information systems and networks, and to discover and repair new weaknesses in systems that billions use everyday.

We sought to study the interaction between the law, technology, and this community. Specifically, since security researchers tend to push into grey areas where the law is unclear, an understanding of the law’s “chilling effects” (inhibition or discouragement) on security research has been a major concern of those who work in and with information security."

UK Government responds to GNSS dependence - call for action - Innovate UK - Mar 2018
"There has been much hype in the GNSS community around a recent report from the Government’s Office for Science (GO-Science) that investigated the dependencies of the UK’s critical services to satellite navigation technology, specifically Global Navigation Satellite Systems (GNSS), such as the American GPS system. The report called for some action and with typical British understatement and quiet resolve, things are happening."

"This article outlines the report, the key findings and the recommendations but also addresses what happens next, which is ultimately the call to arms of the report – take action."

"The key point from this chapter is no single mitigation technology can protect GNSS in all applications. A layered approach, application by application is required to deliver a resilient or robust system. "

"The recommendations do have a common theme; that our GNSS awareness is out of step with our dependence to GNSS and that our knowledge of the vulnerabilities and weaknesses of GNSS should be better. . . . the recommendations can be grouped into some simple sub-sets; improving awareness, improving the legal mechanisms and improving our technical expertise."

Risk Analysis Finds Nuclear Deterrence Wanting - IEEE Spectrum Apr 2008
"Modern nuclear reactors are designed to have a rate of failure, involving the release of significant radiation, of just 1 in 1 million per year per reactor. But what about that other potential source of lethal radiation—nuclear war? Martin E. Hellman, emeritus professor of electrical engineering at Stanford University and IEEE Fellow, applied engineering risk-analysis methods to the question of what the failure rate is for the strategy of nuclear deterrence. His conclusion? The failure rate of nuclear deterrence is a lot higher than you might think."

"The result is a range from 2 chances in 10 000 per year to 5 chances in 1000 per year for just this one type of trigger mechanism. The values are valid only for the Cold War years, writes Hellman. "

[pdf] Coexistence of new services in the 700 MHz band with digital terrestrial television (May 9, 2017)
Via Cyprien De Cosson

Explicitly frame analysis in terms of risk, and risk mitigation.

Exec Summary

1.6 Our projections based on data from the current 800 MHz mitigation scheme indicate that there will be between 25,000 and 36,000 confirmed interference cases by the end of 800 MHz network roll-out. This is less than 0.2% of DTT households in the UK. We expect that the number of 700 MHz interference cases will be broadly similar.

1.9 Households with television receivers that perform poorly1 and that are in an area of relatively high handset activity might experience a single transient picture interruption on average around once every 100 hours of viewing standard definition TV. For high definition (HD), the equivalent figure would be just one interruption in 10,000 hours of viewing.

Accelerating Satellite Data Collection with Regulatory Reform
via Brandt Pasco

"we partnered with DigitalGlobe (DG) and NVIDIA to release labeled, very high resolution satellite imagery on Amazon Web Services as part of SpaceNetTM in order to accelerate this exploration. Other organizations such Planet, Draper, Dstl, IEEE and IARPA have all launched competitions focusing on the analysis of satellite imagery."

" it is worth taking a moment to examine an important factor influencing how startups and incumbents are able to collect and sell satellite data: regulation"

"Venture capital funding and new company starts are at an all-time high (see CB Insights report) and incumbent aerospace firms have made a series of new product announcements (e.g. DG’s Legion story). On the other hand, there has been a growing list of public and private sector stakeholders bemoaning the current state of the U.S.’s outdated remote sensing regulatory framework (e.g., U.S. Rep. Babin, U.S. Rep. Kilmer, Planet, and DG)."

"There are three major concerns with the current process: (1) timeliness of review; (2) predictability; and (3) transparency."

"... the 1992 Land Remote Sensing Policy Act was designed for companies developing a limited number of large satellites. The development timeline for these systems was usually long and required extensive financing. As one might expect, this licensing process has been unable to keep pace with the new, more rapid development and deployment schedules posed by space startups and incumbents with new product lines."

"... NOAA CRSRA is supposed to issue a licensing decision no later than 120 days after submission. Some have described this timeline as “almost an impossible feat” for a variety of reasons ranging from staffing issues to the “stop clock” requirement ..."

"Second, industry’s frustration with licensing delays has been further exacerbated by the lack of predictability of those timelines"

"Third and finally, industry stakeholders have repeatedly expressed their concern with the lack of transparency regarding licensing questions or changes to the existing license conditions. "

FCC: companies "have also expressed some frustration with the increasingly frequent delays. There are two primary causes for these delays: (1) spectrum interference claims and (2) orbital interference claims."

"Despite the legitimate concerns regarding access to spectrum and interference and momentary service disruptions, many interference claims lack detailed analyses quantifying the level of projected risk especially from a low earth orbit (LEO) constellation"

"Proposed policy solutions to the existing regulatory framework remain in their formative stages. Stakeholder opinion ranges from advocating for adjustments to the existing system to a “fundamental rethinking” of the licensing process."

What if…? How reimagining history could help insurers better analyse risk - Lloyd's - The world’s specialist insurance market. Also known as Lloyd's of London; is a market where members join together as syndicates to insure risks.
"Lloyd’s, together with modelling company RMS, have published a new report – entitled Counterfactual Disaster Risk Analysis: Reimagining history – setting out how a type of lateral thinking, called counterfactual, can be applied to complement how insurers analyse risk. The report discusses how downward counterfactual analysis – in other words considering how historical near misses might have become major disasters – can be carried out in practice. It acts as a starting point for future research into counterfactual events and their characteristics. "

[Woo, Catastrophist at RMS, explained]: “Downward counterfactual risk analysis helps address the bias that can be inherent in some models that are based on the same historical data sets. By expanding the data available based on what could have happened, these models can be built with less reliance on single-source data, which might improve their accuracy. It also provides a useful tool for regulators to stress-test catastrophe risk models.”

Aerospace Cybersecurity Challenges Need To Be Identified, Addressed | Connected Aerospace content from Aviation Week
via Dale Hatfield

"The situation illustrates the level of reliance that integral parts of the aviation ecosystem are placing on network connectivity, and the importance of ensuring those networks are both reliable and secure as the industry’s digitalization gains momentum."

"Aviation’s emphasis on systems safety through risk identification and mitigation is well-established."

Pete Cooper, Atlantic Council senior fellow: “Previously, aviation systems were relatively secure due to the bespoke nature of their design, isolation from other systems, and little in the way of communication protocols.”

"Among the [Atlantic Council] study’s key takeaways: Aviation’s march toward an increasingly digital future is opening it up to significant cybersecurity threats, and the industry must move purposefully and quickly to ensure that systemic challenges do not increase an already formidable risk."

"But the consensus among cybersecurity experts and aviation IT specialists is that, while secure systems are the goal, breaches are inevitable. That places the onus on recovery."

Sagan, S.D.: The Limits of Safety: Organizations, Accidents, and Nuclear Weapons (Paperback) | Princeton University Press
Via Steven Bellovin

"Environmental tragedies such as Chernobyl and the Exxon Valdez remind us that catastrophic accidents are always possible in a world full of hazardous technologies. Yet, the apparently excellent safety record with nuclear weapons has led scholars, policy-makers, and the public alike to believe that nuclear arsenals can serve as a secure deterrent for the foreseeable future. In this provocative book, Scott Sagan challenges such optimism. Sagan's research into formerly classified archives penetrates the veil of safety that has surrounded U.S. nuclear weapons and reveals a hidden history of frightening "close calls" to disaster."

Towards an Integrated Assessment of Global Catastrophic Risk by Seth D. Baum, Anthony M. Barrett :: SSRN
Integrated assessment is an analysis of a topic that integrates multiple lines of research. Integrated assessments are thus inherently interdisciplinary. They are generally oriented toward practical problems, often in the context of public policy, and frequently concern topics in science and technology. This paper presents a concept for and some initial work towards an integrated assessment of global catastrophic risk (GCR). Generally speaking, GCR is the risk of significant harm to global human civilization. More precise definitions are provided below. Some GCRs include nuclear war, climate change, and pandemic disease outbreaks. Integrated assessment of GCR puts all these risks into one study in order to address overarching questions about the risk and the opportunities to reduce it. The specific concept for integrated assessment presented here has been developed over several years by the Global Catastrophic Risk Institute (GCRI). GCRI is an independent, nonprofit think tank founded in 2011 by Seth Baum and Tony Barrett (i.e., the authors). The integrated assessment structures much of GCRI’s thinking and activity, and likewise offers a framework for general study and work on the GCR topic.

[pdf] Over-flight Risk Considerations for the Launch of an ELV Rocket to an ISS Inclination
Presented by Steven Millard, AIAA Atmospheric and Space Environments Conference, 2 - 5 August 2010, Toronto, Ontario Canada

"Congress granted the FAA the authority to license commercial launch and reentry operations to ensure protection of public, property, the national security and foreign policy interests of the United States and to encourage, facilitate, and promote U.S. Commercial Space Transportation. To meet this responsibility, the FAA performs safety evaluations of license applications to conduct commercial launches from the United States or outside the United States by a U.S. citizen or an entity organized under the laws of the United States. This paper discusses an example FAA analysis of the risk to the public resulting from the launch of a space vehicle to the International Space Station from a launch site at the Eastern Range, headquartered at Cape Canaveral, Florida, and the Mid-Atlantic Regional Spaceport, located in Wallops, Virginia. This work is presented to address some of the challenges launch operators competing for the Commercial Orbital Transportations Services (COTS) and the FAA face in their efforts to promote commercial space activities while ensuring the launch operator meets their regulatory obligations and responsibility for protecting the public.

"Satellites swarms could increase space junk risk by 50 per cent
SWARMS of cheap CubeSats set to deliver internet access to every corner of the globe could cause a 50 per cent rise in catastrophic collisions with other satellites, unleashing hazardous space junk."

"Hugh Lewis at the University of Southampton, UK, and his colleagues used a supercomputer to simulate 200 years of possible orbits for 300 different scenarios.

The results, presented this week at a European Space Agency conference on space debris in Darmstadt, Germany, suggest that these megaconstellations boost the risk of a catastrophic collision – in which a satellite is destroyed – by 50 per cent."

Proposal to Amend EU Comitology Rules: Stretching the Limits of the Precautionary Principle | Global Policy Watch
"The European Commission has presented a proposal to amend the EU’s examination comitology procedure with the aim of forcing Member States to vote and take responsibility in the adoption of controversial decisions mostly affecting health and the environment, such as pesticides, GMOs, and chemicals.  If adopted, the proposed amendments are likely to result in an even stronger precautionary approach and the adoption of fewer approvals of politically sensitive products in the EU.  The amendments would also mean that companies who seek to have such products approved will need to put more efforts into influencing Member States and their national constituencies.  They are also likely to result in increased litigation before the EU Courts."

"In practice, the examination procedure results in a no opinion situation that forces the Commission to decide on its own in around less than 2% of all the proposals that the Commission presents."

"Given the domestic political sensitivity of approvals on pesticides, GMOs and similar decisions, Member States will often prefer not to participate in the adoption of what is ultimately a political decision even if the Commission’s proposal is supported by the EU’s scientific bodies."

"In effect, the proposed amendments would emphasize the application of the precautionary principle in the EU and, are likely to discredit it in the long run."

"Research Question: What are the research and other needs that either address concerns or take advantage of opportunities related to emerging technologies and the protection of individuals' constitutional rights in the criminal justice system?"

"Via a Delphi-based prioritization of the results, the panel crafted a research agenda — including best practice and training development, evaluation, and fundamental research efforts — to provide the criminal justice community with the knowledge and capabilities needed to address these important and complex technological questions going forward."

"The panel's research agenda prioritized needs that fell into three categories: best practice and training development, addressing such issues as criminal justice data quality and its implications for individuals' rights; evaluation work to better understand how analytic tools (such as risk assessment instruments) perform; and fundamental research on such topics as how the exploding volume of electronic data could affect the protection of rights."

"Among the issues raised by the panel, the need to educate participants in the criminal justice system was most prominent."

FAA Reauthorization Bill Still Leaves Much To Be Desired For Commercial Drone Operators | TechCrunch Feb 2016
"The U.S. Federal Aviation Administration is due for reauthorization and the Transportation & Infrastructure Committee introduced the first draft of the FAA bill today. While the efforts to reform the air traffic control system will likely take center stage in the discussion around the bill, it also includes a number of items around the commercial use of drones." "For the most part, the new bill rehashes the FAA’s language around commercial drones. What’s new, though, is that the bill asks the FAA to take a risk-based approach to permitting. The idea here is to look at, among other things, location, the nature of the mission, known failure modes and both the technology’s and the operator’s safety record."

Ozone hole: How we are misled in the fight to cut smog - opinion - 02 February 2015 - New Scientist
"Republicans now control both houses of Congress and are all for throttling President Barack Obama's plans to lower the federal limit on ozone smog, announced by the US Environmental Protection Agency (EPA) right after the elections. They say it is unachievable, except at vast cost. This might surprise Europeans, who have been living with a tougher limit for some time. However, an analysis for New Scientist suggests that Europe's limits are less stringent than they appear." - "In the US, being in breach of the regulations means exceeding the limit on four or more days in a year, averaged over three years. So 11 breaches in any three-year period is fine, but 12 is not. In Europe, the limit can be exceeded up to 25 days a year, again averaged over three years. So up to 75 bad-air days are allowed in that time. That's a lot, but even so large parts of southern Europe failed that test for the period 2011 to 2013, because of a spike during the hot summer of 2013."

The latter is an inherently political question." "Both pro- and anti-nuclear advocates have argued that nuclear plants should be restarted if and only if they can withstand a "worst-case" scenario – albeit with each side trying to game the definition of the worst case. This may sound sensible, but it is logically flawed. When it comes to natural hazards there is no "worst case"."

How ‘hazards’ drive broadband economics
The broadband supply has four key properties: Connectivity; Continuity; Capacity; Stationarity - "These four factors in turn determine the performance hazards of the application. For instance, what are the chances that a streaming video application will exhaust its buffer and show the ‘circle of death’? This concept of hazards is a central and critical idea. It is borrowed from the study of safety-critical systems (like air traffic control) and the analysis of their failure modes. A performance hazard can be latent, i.e. it could happen, but not in the current circumstances. This is a bit like being the carrier of a gene sequence that pre-disposes you to a disease that will only afflict you in later life. Alternatively, the hazard could bearmed, and could happen in the current circumstances. Armed hazards have a certain probability of maturing which results in an impact that drives business risk."

In order to affect design and procurement decisions, DoD Components shall: Identify spectrum-related risks as early as possible via Spectrum Supportability Risk Assessments (SSRA). Review these assessments at acquisition milestones. Manage the risks throughout the system’s lifecycle. These FAQs will serve as the vehicle to address the TriSysCom (NAVSEA, SPAWAR,NAVAIR) questions that have accumulated with the SSRA submittal process and SSRA content. They are to be used in conjunction with the DoD “Joint Services Guide for Development of a Spectrum Supportability Risk Assessment (SSRA)”.

Spectrum Supportability Risk Assessment (SSRA)
"DoDI 4650.01 requires system developers of spectrum dependent (S-D) systems and equipment to identify and mitigate regulatory, technical, and operational spectrum supportability (SS) and electromagnetic environmental effects (E3) risks during the development process. The instruction also requires that the resulting spectrum supportability risk assessment (SSRA) be updated to provide increasing levels of detail as the item's design matures. The SSRA constitutes the basis for milestone decision authority determinations of spectrum supportability and provides increasing levels of detail regarding a system’s regulatory, technical, and operational requirements in Initial, Detailed, and Updated SSRAs."

Announcement from Electromagnetics and Spectrum Engineering Group | LinkedIn
"I invite you to join the new LinkedIn Group Spectrum Supportability Risk Assessments! SSRAs are a relatively new US DoD requirement to identify and assess an systems's potential to affect its required performance or the performance of other systems within the operational EME. This assessment must be accomplished with due consideration given to regulatory, technical, and operational spectrum and E3 issues and assigned risks. This new group will provide a forum for discussions and questions related to the development, submittal and review of SSRAs. Try https://www.linkedin.com/groups?home=&gid=8252522&trk=anet_ug_hm&goback=%2Egmr_8252522 or search in the groups for Spectrum Supportability!"

To Hit the Road, Driverless Cars Must Be Safe, Not Perfect | RAND
"Once driverless cars are safer than the average human driver, we should let them hit the road. Indeed, waiting for autonomous vehicles to be perfect would be its own safety concern because it would mean the needless perpetuation of the risks posed by human drivers. In the United States alone, some 30,000 people are killed and more than 2 million injured in crashes every year (PDF), and the vast majority (PDF) of them are caused by human error."
