Top-down Process Mining from Multi-source Running Logs Based on Refinement of Petri Nets

Qingtian Zeng, Hua Duan, Cong Liu
2020 IEEE Access  
Running logs are a valuable source of information about the actual execution of the distributed information systems.  ...  Today's information systems of enterprises are incredibly complex and typically composed of a large number of participants.  ...  The firing rules of the top-level process model are defined as follows: t is enabled under M iff ∀p ∈ • t, M (p) ≥ 1. These rules are different from that of a standard Petri net.  ...

2015 arXiv   pre-print
In public discussions of the quality of forecasts, attention typically focuses on the predictive performance in cases of extreme events.  ...  However, the restriction of conventional forecast evaluation methods to subsets of extreme observations has unexpected and undesired effects, and is bound to discredit skillful forecasts when the signal-to-noise  ...  ACKNOWLEDGMENTS The support of the Volkswagen Foundation through the project 'Mesoscale Weather Extremes -Theory, Spatial Modeling and Prediction (WEX-MOP)' is gratefully acknowledged.  ...

Squashed embedding of E-R schemas in hypercubes

Chaitanya K. Baru, Piyush Goel
1990 Journal of Parallel and Distributed Computing  
In general, the dimension of the cube required for squashed embedding of a graph is called the weak cubical dimension or WCD of the graph.  ...  We have been investigating an approach to parallel database processing based on treating Entity-Relationship (E-R) schema graphs as datallow graphs.  ...  Thus, the bounds on the RS-WCD of G,,, are dmin = r log,( m + n)l 6 RS-WCD < rlog,ml + llog,nl = d,,,,.  ...

Temporal dynamics of gene expression and histone marks at the Arabidopsis shoot meristem during flowering

Yuan You, Aneta Sawikowska, Manuela Neumann, David Posé, Giovanna Capovilla, Tobias Langenecker, Richard A. Neher, Paweł Krajewski, Markus Schmid
2017 Nature Communications  
At the time of flowering, the SAM of Arabidopsis thaliana switches fate and starts producing flowers instead of leaves.  ...  How epigenetic regulation contributes to the floral transition has eluded analysis so far, mostly because of the poor accessibility of the SAM.  ...  Work on flowering time in the Schmid lab is supported through grants from the Vetenskapsrådet (VR; 2015-04617) and the Knut and Knut and Alice Wallenberg Foundation (KWA; 2016.0025).  ...

Shortest path queries in planar graphs

Danny Z. Chen, Jinhui Xu
2000 Proceedings of the thirty-second annual ACM symposium on Theory of computing - STOC '00  
The problem of processing shortest path queries in graphs arises in application areas such as intelligent transportation system (ITS), geographic information system (GIS), and robotics.  ...  This data structure enables us to process each length query in O(v/-rlog r + a(n)) time and report an actual shortest path in an additional O(L) time, where a(n) is the inverse of Ackermann's function.  ...  (Experiments have shown that a database or disk based approach cannot meet the requirements of such real-time systems [20] .)  ...
