This paper presents a Monte Carlo method for analyzing the space of trajectories entailed by a qualitative differential equation and deriving statistical properties of qualitative behaviors. Estimates of the occurrence probability of behaviors and estimates of parameters defined over numerical trajectories can be computed and used in several ways. For example, behavior probability can be used t...

BACKGROUND Sampling methods have proven to be a very efficient and intuitive method to understand properties of complicated spaces that cannot easily be computed using deterministic methods. Therefore, sampling methods became a popular tool in the applied sciences. RESULTS Here, we show that sampling methods are not an appropriate tool to analyze qualitative properties of complicated spaces u...

1 Abstract All the qualitative simulation algorithms so far proposed depend upon local propagation paradigm, and hence produce spurious states. Recent approaches use topological constraints in phase space diagrams for filtering the spurious states. We propose an alternative method of recognizing global properties in the graphically expressed qualitative model. Qualitative versions of such syste...

We consider a switched network, a fairly general constrained queueing network model that has been used successfully to model the detailed packet-level dynamics in communication networks, such as input-queued switches and wireless networks. The main operational issue in this model is that of deciding which queues to serve, subject to certain constraints. In this paper, we study qualitative perfo...

Qualitative spatial and temporal reasoning is based on socalled qualitative calculi. Algebraic properties of these calculi have several implications on reasoning algorithms. But what exactly is a qualitative calculus? And to which extent do the qualitative calculi proposed meet these demands? The literature provides various answers to the first question but only few facts about the second. In t...

In this study, physico-chemical properties of honeys samples obtained from different locations of Turkey were investigated. Moisture, diastase activity, Hydroxy Methyl Furfural (HMF), viscosity, acidity, total glucose+fructose, protein and ash contents of honey samples ranged from 17.1% to 20.0%, 10.9 to 17.9, 1.34 to 31.28 mg/kg, 2.48 to 8.42 Pa s, 18.2 to 47.5 meq/kg, 51.31% to 68.30%, 0.60% ...

When we construct mathematical or numerical models in order to solve a real-life problem, it is important to preserve the characteristic properties of the original process. The models have to possess the equivalents of these properties. Parabolic partial equations generally serve as the mathematical models of heat conduction or diffusion processes, where the most important properties are the mo...

Suppose that a consistent one-step numerical method of order r is applied to a smooth system of ordinary differential equations. Given any integer m > 1, the method may be shown to be of order r + m as an approximation to a certain modi"ed equation. If the method and the system have a particular qualitative property then it is important to determine whether the modi"ed equations inherit this pr...
