New challenges in certification for aircraft software

John Rushby
2011 Proceedings of the ninth ACM international conference on Embedded software - EMSOFT '11  
We outline the current approach to certification of aircraft software, and the rôle of the DO-178B guidelines. We consider evidence for its effectiveness and discuss possible explanations for this.  ...  We then describe how changes in aircraft systems and in the air traffic system pose new challenges for certification, chiefly by increasing the extent of interaction and integration.  ...  Methods of software development and assurance evolve much more rapidly than aircraft systems.  ...

On Software Certification: We Need Product-Focused Approaches [chapter]

Alan Wassyng, Tom Maibaum, Mark Lawford
2010 Lecture Notes in Computer Science  
We make the case that productfocused certification is required to produce reliable software intensive systems. These techniques will have to be domain and even product specific to succeed.  ...  We then review current practices in software certification and contrast the software regime's process-oriented approach to certification with the product-oriented approach typically used in other engineering  ...  The documents do not do a good enough job of describing the artefacts that will be assessed.  ...

Assurance cases and prescriptive software safety certification: A comparative study

Richard Hawkins, Ibrahim Habli, Tim Kelly, John McDermid
2013 Safety Science  
There has been much debate surrounding the relative merits of prescriptive and safety assurance argument approaches to certification. In many ways this debate can lead to confusion.  ...  This approach to certification is often described as prescriptive or process-based certification.  ...  For reasons of brevity, we do not define those criteria here. These software safety requirements will be further refined as more design detail becomes available (Lee et al., 2010) .  ...

Formal Methods and their Role in the Certification of Critical Systems [chapter]

John Rushby
1997 Safety and Reliability of Software Based Systems  
Its purpose is to outline the technical basis for formal methods in computer science, to explain the use of formal methods in the specification and verification of software and hardware requirements, designs  ...  benefits, weaknesses, and difficulties in applying these methods to digital systems used in critical applications, and to suggest factors for consideration when formal methods are offered in support of certification  ...  expect a large piece of software to be more of a challenge than a smaller one.  ...

Justifying Class Action Limits: Parsing the Debates over Ascertainability and Cy Pres

2017 Kansas Law Review  
Some judges believe they have more latitude to approve a cy pres provision in a settlement than they do to employ cy pres after a trial judgment. See, e.g., Marshall v.  ...  It is possible, for example, that an attorney would be more willing to sell out a class with anonymous members than a class whose members the attorney knows or could imagine knowing.  ...  flexible approach, 219 and the analogy with (b)(2) supports doing so.  ...

The Next Generation Internet: a selection of contributions to the debate

Nadia El-Imam
2021 Zenodo  
This, in the NGI consortium's intentions, would make the platform more thought-provoking, and therefore more engaging.  ...  To do so, we used a combination of open calls for contributions and targeted interviews to identified thought leaders.  ...  The debate centres around whether it will be used for good or evil.  ...

Debating Abortion, Deliberative Reciprocity and Parliamentary Advocacy

Albert Weale, Aude Bicquelet, Judith Bara
2012 Political Studies  
Utilising the software Alceste to conduct automated text analysis, it finds that debate does not match the prediction of parties merely talking past one another.  ...  The inconsistency could arise from not considering plausible conditions of democratic debate in which reciprocity might be respected, such as legislative debates free of party discipline.  ...  knight, who spoke very movingly. after all, a woman has much more right to speak in this debate than has any other hon.  ...

Standards for Duty of Care? Debating Intermediary Liability from a Sectoral Perspective

Carsten Ullrich
2017 Social Science Research Network  
Then forcing information sharing duties on intermediaries, which risk exposing company confidential data, would do more to alienate stakeholders rather than bringing them together.  ...  They will then be awarded with a certificate identifying them as an approved online pharmacy, which they will need to display on each offer detail page.  ...  know-your-customer (KYC) obligations applied to intermediaries. 127 While Article 5 ECD refers only to the information Member States may require of ISPs, it appears rights holders lament the fact that intermediaries do  ...

Gender, Candidate Emotional Expression, and Voter Reactions During Televised Debates

CONSTANTINE BOUSSALIS, TRAVIS G. COAN, MIRYA R. HOLMAN, STEFAN MÜLLER
2021 American Political Science Review  
Consistent with our expectations, Angela Merkel expresses less anger than her male opponents, but she is just as emotive in other respects.  ...  Relying on full-length videos of four German federal election debates (2005–2017) and a minor party debate, we use video, audio, and text data to measure candidate facial displays of emotion, vocal pitch  ...  express more happiness than will men, and men will express more anger than will women.  ...

Kurt Eggert
2007 Housing Policy Debate  
Subprime servicers depend far more on ancillary income, such as late fees, than prime servicers do.  ...  Given the large number of subprime borrowers with loans that are resetting to significantly higher rates, servicers will often have to do more to prevent foreclosures than just make early contact and offer  ...
