The Mathematical Foundations of Physical Systems Modeling Languages [article]

Albert Benveniste
2021 arXiv   pre-print
For our mathematical development, we rely on nonstandard analysis, which allows us to cast hybrid systems dynamics to discrete time dynamics with infinitesimal step size, thus providing a uniform framework  ...  In this paper, we develop a comprehensive mathematical approach supporting compilation and code generation for this class of languages. Its core is the structural analysis of multimode DAE systems.  ...  We had extensive fruitful discussions with John Pryce on both structural analysis of DAEs, including the Σ-method}, and physical modeling in general; this helped us bring out the need for an explicit distinction  ...

Provisioning QoS features for input-queued ATM switches

S. Li, N. Ansari
1998 Electronics Letters  
ABSTRACT ON SCHEDULING INPUT QUEUED CELL SWITCHES by Shizhao Li Output-queued switching, though is able to offer high throughput, guaranteed delay and fairness, lacks scalability owing to the speed up  ...  This dissertation presents three approaches toward resolving the major problem encountered in input-queued switching that has prohibited the provision of quality of service guarantees.  ...  Since SSF is a non-work-conserving scheduler, the performance analysis can be extended from a single node to a network with arbitrary topology, and more efficient usage of buffer space than work-conserving  ...
