Finite limits and monotone computations: the lower bounds criterion
Proceedings of Computational Complexity. Twelfth Annual IEEE Conference
Apparently this is the rst combinatorial lower bounds criterion for monotone computations. It is symmetric and yields (in a uniform and easy way) exponential lower bounds. ...
The proof is relatively simple and direct, and combines the bottlenecks counting approach of Haken with the idea of nite limit due to Sipser. ...

I thank Armin Haken, Alexander Razborov and Avi Wigderson for interesting discussions and remarks. ...

SPARQL for a Web of Linked Data: Semantics and Computability
[chapter]
2012
Lecture Notes in Computer Science
For both models we discuss properties such as monotonicity and computability as well as the implications of querying a Web that is infinitely large due to data generating servers. ...
The World Wide Web currently evolves into a Web of Linked Data where content providers publish and link data as they have done with hypertext for the last 20 years. ...
It is easy to see that any SPARQL LD(R) query which uses an empty set of seed URIs is not satisfiable and, thus, monotonic and finitely computable. ...

A Finite-Volume Method for Convection Problems with Embedded Moving-Boundaries
[chapter]
2009
Computational Fluid Dynamics 2008
Tailor-made limiters are derived such that the resulting scheme is monotone. The results obtained are very accurate, without requiring much computational overhead. ...
Monotonicity and Limiters Noting that the EB-affected cell-face states (7) are higher-order accurate and linear, wiggles are imminent. ...
We define non-standard monotonicity arguments,r i− 1 2 andr i+ 3 2 , and derive the limited forms of c i− 1 2 and c i+ 3 2 (see [1] for details). c i+ 1 2 , however, is not limited as we can not define ...

We also intro- duce the idea of a limit automaton of a class and using this concept we analyse the finite recognizability of a class and its subclasses. ...
We show that all the automata belonging to a finite definable class, except for the limit automata, form a finitely recognizable class of automata. ...

The expressive power of indeterminate dataflow primitives
1992
Information and Computation
The trace set of any finite network built out of Hoare-monotone and limit-closed processes by aggregation, feedback and output hiding is Hoare-monotone, and hence the input-output relation is also Hoaremonotone ...
The aggregate of two networks, N and M, with Hoaremonotone and limit-closed trace sets has a Hoare-monotone and limit-closed trace set. ...

Statistical properties of the error covariance in a Kalman filter with random measurement losses
2010
49th IEEE Conference on Decision and Control (CDC)
A similar analysis leads to a necessary condition on the measurement arrival probability for the error covariance to have a finite asymptotic variance. 49th IEEE Conference on Decision and Control ...
Although we have not yet shown the monotonic convergence of this whole sequence, monotonic convergent subsequences are identified. ...

The Theory of WSTS: The Case of Complete WSTS
[chapter]
2012
Lecture Notes in Computer Science
Karp and Miller [KM69] proposed an algorithm, for Petri nets, which computes a finite representation of the cover , i.e., of the downward closure of the reachability set of a Petri net. ...
This computes the so-called clover of a state. When S is the completion of a WSTS X, the clover in S is a finite description of the downward closure of the reachability set. ...

Physical Review D, Particles and fields
As a result of a two-loop computation we obtain, in the large N 't Hooft limit, F(g^2N→ 0)≈ -π^2/6N^2V_3T^4(1-3/2π^2g^2N). ...
