We consider multi-agent scenarios where each agent controls a surveillance camera positioned in the plane, with fixed position and angle of view, but rotating freely. The agents can thus observe the surroundings and each other. They can also reason about each other’s observation abilities and knowledge derived from these observations. In this demonstration, cameras are located in the plane. The...

The acid-mediation hypothesis, that is, the hypothesis that acid produced by tumours, as a result of aerobic glycolysis, provides a mechanism for invasion, has so far been considered as a relatively closed system. The focus has mainly been on the dynamics of the tumour, normaltissue, acid and possibly some other bodily components, without considering the effect of an external intervention such ...

This paper refers to some closed two-stage queueing systems with state-dcpendent vacation policy. By means of the markovian rcnewal process and the stochastic decomposition formulas of the quantities in equilibrium for M/Gjl vacation models, we derive both stationary distributions of the queue length and the cyclic time for the closed state-dependcnt vacation model. We try to so!\'e the problem...

Recently, there have appeared interesting correctives or challenges [Entropy 1999, 1, 111-147] to the Second law formulations, especially in the interpretation of the Clausius equivalent transformations, closely related in area to extensions of the Clausius principle to irreversible processes [Chem. Phys. Lett. 1988, 143(1), 65-70]. Since the traditional formulations are central to science, a b...

A reactive system’s slow dynamic behavior is approximated well by its evolution on manifolds of dimension lower than the dimensionality of the full composition space. This work addresses the relation between the isothermal reactive systems’ slow dynamics, described by the actual slow invariant manifolds, and notions from thermodynamics. In addition to mathematical proof, a realistic reactive sy...

The superform construction of supersymmetric invariants, which consists of integrating the top component of a closed superform over spacetime, is reviewed. The cohomological methods necessary for the analysis of closed superforms are discussed and some further theoretical developments presented. The method is applied to higher-order corrections in heterotic string theory up to α. Some partial r...

We investigate the dynamics of a spherically symmetric vaccum on a Randall and Sundrum 3-brane world. Under certain natural conditions, the effective Einstein equations on the brane form a closed system for spherically symmetric Kaluza-Klein dark radiation. We determine exact dynamical and inhomogeneous solutions, which are shown to depend on the brane cosmological constant, on the dark radiati...

In recent years many theorists within the field of critical realism have highlighted the drive within modern mainstream economics towards mathematical modelling (Lawson 1997; Fleetwood 1999). Simultaneously, a group of French economics students have criticised the discipline, describing it as autistic and calling for a return to reality (Devine 2002). More recently, a theory has been advanced d...

Supervisory control and data acquisition (SCADA) systems are widely used to monitor and control operations in electrical power distribution facilities, oil and gas pipelines, water distribution systems and sewage treatment plants. Technological advances over the past decade have seen these traditionally closed systems become open and Internet-connected, which puts the service infrastructures at...

This paper provides a framework for control design and simulation of a closed-loop system with partial input/output data of a plant. Given the input/output crosscorrelation and output autocorrelation data of an open loop dynamic system, a simulation model implemented in fixed-point digital devices which matches these data is obtained using q-Markov Covariance Equivalent Realizations. These resu...
