Fluχ: a quality-driven dataflow model for data intensive computing

Sérgio Esteves, João Nuno Silva, Luís Veiga
2013 Journal of Internet Services and Applications  
For example, considering dataflows that continuously analyze data upon the insertion/update of new entries in a data store, it would be wise to assess the level of modifications in data, before the trigger  ...  on the evaluation and dynamic enforcement of QoD constraints that are defined (and possibly adjusted automatically) for different sets of data.  ...  We also would like to thank the anonymous reviewers who greatly contributed to the betterment of this work.  ...

Improving the Precision of Equality-Based Dataflow Analyses [chapter]

Erik Ruf
2002 Lecture Notes in Computer Science  
We present two new, orthogonal techniques for improving the precision of equality-based dataflow analyses.  ...  Subtype expansion models objects at a per-type granularity, enabling a form of subtype-restricted equality constraint, while mutation tracking uses a simple effect analysis to avoid a class of false aliases  ...  Acknowledgements We thank the ex-members of the Advanced Programming Languages group at Microsoft Research for developing the Marmot compiler infrastructure, and Todd Knoblock, Bjarne Steensgaard, and  ...

A Language for Modelling False Data Injection Attacks in Internet of Things [article]

Mathieu Briland, Fabrice Bouquet
2021 arXiv   pre-print
Internet of Things (IoT) is now omnipresent in all aspects of life and provides a large number of potentially critical services. For this, Internet of Things relies on the data collected by objects.  ...  In this work, we dissect and present a method that uses a Domain-Specific Language (DSL) to generate altered data, allowing these attacks to be simulated and tested.  ...  This approach can then be used for several purposes as to test the resilience of a system or to train machine learning tools to detect such attacks.  ...
