A Study on Mining User-Aware Uncommon Consecutive Topic Patterns in Report Streams

Ankit Gururaj
2016 Asia-pacific Journal of Convergent Research Interchange  
Rare Sequential Topic Patterns (URSTPs) in archive streams on the Internet.  ...  In this paper, keeping in mind the end goal to describe and identify customized and anomalous practices of Internet clients, we propose Sequential Topic Patterns (STPs) and figure the issue of mining User-mindful  ...  Advantages of proposed system To the best of our insight, this is the principal work that gives formal definitions of STPs and their irregularity measures, and advances the issue of mining URSTPs in document  ...

Engineering mathematics

Georges Gonthier
2013 SIGPLAN notices  
By combining tools and techniques from type theory, language design, and software engineering we have managed to capture enough of these practices to formalize the proof of the Odd Order theorem, a landmark  ...  Even with the assistance of computer tools, the formalized description and verification of research-level mathematics remains a daunting task, not least because of the talent with which mathematicians  ...  The prerequisites represent about twice that amount, from a variety of sources. The Coq formalization of the 1300 lemmas of the proof spans 47,000 LOC (out of 170,000 for the full archive).  ...

Nonoutsourceable Scratch-Off Puzzles to Discourage Bitcoin Mining Coalitions

Andrew Miller, Ahmed Kosba, Jonathan Katz, Elaine Shi
2015 Proceedings of the 22nd ACM SIGSAC Conference on Computer and Communications Security - CCS '15  
We argue that the prevalence of mining coalitions is due to a limitation of the Bitcoin proof-of-work puzzle -specifically, that it affords an effective mechanism for enforcing cooperation in a coalition  ...  Recently, the largest mining pool has accounted for more than half of network's total mining capacity.  ...  Acknowledgments We thank the readers and reviewers of earlier drafts of this paper. This work was supported in part by NSF awards #0964541, #1223623, and #1518765.  ...

Moreover, we implement a proof-of-concept tool named PLCInspector that supports directly mining LTL specifications and data invariants from PLC programs.  ...  It only requires users to review specifications mined from the program behaviors instead of model checking for specified specifications, which can greatly improve the efficiency of safety verification  ...  [2] provided the semantics of SFC and IL, formalized in the proof assistant Coq, while [3] and [27] discussed their verification based on model checking.  ...
