Generalized complex structures were introduced as a common format for discussing both symplectic and complex manifolds, but the most interesting examples are hybrid objects – part symplectic and part complex. One such class of examples consists of holomorphic Poisson surfaces, but in [5],[6] Cavalcanti and Gualtieri also construct generalized complex 4-manifolds with similar features which are ...

 This paper present unequal-sized facilities layout solutions generated by a genetic search program named LADEGA (Layout Design using a Genetic Algorithm). The generalized quadratic assignment problem requiring pre-determined distance and material flow matrices as the input data and the continuous plane model employing a dynamic distance measure and a material flow matrix are discussed. Computa...

Future wireless Am networks are expected to support a variety of services with different bit-rates and Quality-of-Service (QoS) requirements. A major challenge for these networks is the de= sign of the multiple access scheme. In our previous works, we proposed hybrid CDMA/TDMA technique as an appropriate multiple access control (MAC) scheme for wireless Am networks. We also investigated the pro...

Timed modal speciications have proven useful for the veri-cation of real time systems. In the paper, we show how the notion of modal transitions systems, the basic formalism of timed modal specii-cations, can be generalized to modal hybrid systems. This allows verii-cation problems for hybrid systems to be formulated using the notion of (weak) reenement, a generalization of bisimulation. We als...

In practice the systems are not only pure discrete event or pure continuous, but they are combined from discrete and continuous parts together. These systems are called hybrid systems. Hybrid Petri nets (HPNs) allow modeling and analysis of hybrid systems. Since classical HPNs cannot properly model the systems with the delays on continuous product flow, extended Hybrid Petri nets and generalize...

given a mapping $f:xto x$ we naturally associate to it a monotonic map $gg_f:exp xto exp x$ from the power set of $x$ into itself, thus inducing a generalized topology on $x$. in this paper we investigate some properties of generalized topologies which are defined by such a procedure.

Hybrid automata provide a language for modeling and analyzing digital and analogue computations in real-time systems. Hybrid automata are studied here from a dynamical systems perspective. Necessary and sufficient conditions for existence and uniqueness of solutions are derived and a class of hybrid automata whose solutions depend continuously on the initial state is characterized. The results ...

In this paper, we present a framework for the hybrid omnidirectional and perspective robot vision system. Based on the hybrid imaging geometry, a generalized stereo approach is developed via the construction of virtual cameras. It is then used to rectify the hybrid image pair using the perspective projection model. The proposed method not only simplifies the computation of epipolar geometry for...

It is known that the restarted full orthogonalization method (FOM) outperforms the restarted generalized minimum residual method (GMRES) in several circumstances for solving shifted linear systems when the shifts are handled simultaneously. On the basis of theWeightedArnoldi process, aweighted version of the Restarted Shifted FOM is proposed, which can provide accelerating convergence rate with...
