Restricted Predicates for Hypothetical Datalog [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
Hypothetical Datalog is based on an intuitionistic semantics rather than on a classical logic semantics, and embedded implications are allowed in rule bodies.

On Some Generalizations of Reverse Dynamic Hardy Type Inequalities on Time Scales

open access: yesAxioms, 2022
In the present paper, we prove some new reverse type dynamic inequalities on T. Our main inequalities are proved by using the chain rule and Fubini’s theorem on time scales T. Our results extend some existing results in the literature.

Mine Productivity Upper Bounds and Truck Dispatch Rules

open access: yesMining, 2023
This paper proposes an upper bound for mine productivity (useful for long-term planning) and also a simple truck dispatch rule (useful for short-term operations) that demonstrates how tight the upper bound can be using a simulation.

Taming Existence in RDF Querying [PDF]

open access: yes, 2008
We introduce the recursive, rule-based RDF query language RDFLog. RDFLog extends previous RDF query languages by arbitrary quantifier alternation: blank nodes may occur in the scope of all, some, or none of the universal variables of a rule.

Semantic Rule-Based Equipment Diagnostics [PDF]

open access: yes, 2017
Industrial rule-based diagnostic systems are often data-dependant in the sense that they rely on specific characteristics of individual pieces of equipment. This dependence poses significant challenges in rule authoring, reuse, and maintenance by engineers.

Compositionality of Approximate Bisimulation for Probabilistic Systems [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
Probabilistic transition system specifications using the rule format ntmuft-ntmuxt provide structural operational semantics for Segala-type systems and guarantee that probabilistic bisimilarity is a congruence.

Initial Draft of a Possible Declarative Semantics for the Language [PDF]

open access: yes, 2005
This article introduces a preliminary declarative semantics for a subset of the language Xcerpt (so-called grouping-stratifiable programs) in form of a classical (Tarski style) model theory, adapted to the specific requirements of Xcerpt’s constructs ...

Multi-Step Quantum Numerical Techniques for Finding the Solutions of Nonlinear Equations

open access: yesMathematics, 2022
In this paper, we analyze the q-iterative schemes to determine the roots of nonlinear equations by applying the decomposition technique with Simpson’s 13-rule in the setting of q-calculus.

Rule-Based Semantic Sensing [PDF]

open access: yes, 2011
Rule-Based Systems have been in use for decades to solve a variety of problems but not in the sensor informatics domain. Rules aid the aggregation of low-level sensor readings to form a more complete picture of the real world and help to address 10 identified challenges for sensor network middleware. This paper presents the reader with an overview of a

Evaluating the performance of model transformation styles in Maude [PDF]

open access: yes, 2011
Rule-based programming has been shown to be very successful in many application areas. Two prominent examples are the specification of model transformations in model driven development approaches and the definition of structured operational semantics of ...
