A New Elimination-Based Data Flow Analysis Framework Using Annotated Decomposition Trees [chapter]

Bernhard Scholz, Johann Blieberger
Lecture Notes in Computer Science  
We introduce a new framework for elimination-based data flow analysis. We present a simple algorithm and a delayed algorithm that exhibit a worstcase complexity of O(n 2 ) andÕ(m).  ...  The algorithms use a new compact data structure for representing reducible flow graphs called Annotated Decomposition Trees.  ...  Acknowledgement We would like to thank Bernd Burgstaller, Shirley Goldrei, and Wei-ying Ho for their useful comments and for proof-reading the manuscript.  ...

Assurance via workflow+ modelling and conformance [article]

Zinovy Diskin, Nicholas Annable, Alan Wassyng, Mark Lawford
2019 arXiv   pre-print
Precise dataflow modelling signifies a crucial distinction of (WP+)-based and GSN-based assurance, in which the data layer is mainly implicit.  ...  These workflows are based on precise data modelling as in functional block diagrams, but their distinctive feature is the presence of relationships between the output data of a process and its input data  ...  ,Process 3b.1 takes a pair (H,PS) consisting of a hazard H and a PS intended to mitigate H, uses this data to conduct a fault tree analysis, and outputs the Real Probability of H occuring with PS in place  ...

Multiple targets can be tracked simultaneously within a unified framework without explicit data association between observations and tracking targets.  ...  Initially, points of interest (POIs) are divided by the proposed colored R-tree (RC-tree)-based algorithm into the bounded areas for each station.  ...  Besides, there are three large-scale data sets that annotate both vehicles and license plates, where one is a private data set and the other two are re-annotated from the public data sets.  ...

2010 Proceedings of the 2010 ICSE Workshop on Software Engineering for Sensor Network Applications - SESENA '10  
Developing of a robust macroprogramming compiler framework poses a unique challenge because users need to create optimized function decompositions, in a modular way, such that they can be composed with  ...  Our results show that the introduction of new decompositions and compiler optimizations can be accomplished with a small number of lines of code and typically written in a matter of hours.  ...  Once a control flow graph is constructed, dependency analysis will be used to eliminate variables that are not part of an actuation.  ...

2013 Proceedings of the 2nd ACM SIGPLAN workshop on Functional high-performance computing - FHPC '13  
For large scale graphs that have billions of edges or vertices, these problems are hard to be computed directly even using popular data-intensive frameworks like MapReduce or Pregel that are deployed on  ...  In this paper, we propose a novel programming framework which provides a user-friendly programming interface and automatic in-black-box parallelization.  ...  As a tree decomposition of a graph is an instance of the tree data structure, our parallelization approach for graph problems is based on both tree decomposition and tree parallelization.  ...
