In this thesis, we present our approach to add dynamism support to simulation environments, which adopts DEVS-based modeling and simulation approach and builds upon previous work on SiMA, a DEVS-based simulation framework developed at TUBITAK UEKAE. Defining and executing simulation models of complex and adaptive systems is often a non-trivial task. One of the requirements of simulation software frameworks for such complex and adaptive systems is that supporting variable structure models, which can change their behavior and structure according to the changing conditions. In the relevant literature there are already proposed solutions to the dynamism support problem. One particular contribution offered in this study over previous approaches is the systematic and automatic framework support for poststructural-change state synchronization among models with related couplings, in a way that benefits from the strongly-typed execution environment SiMA provides. In this study, in addition to introducing theoretical extensions to classic SiMA, performance comparisons of dynamic version with classic version over a sample Wireless Sensor Network simulation is provided and possible effects of dynamism extensions to the performance are discussed.

Variable structure and dynamism extensions to SiMA, a DEVS based modeling and simulation framework Deniz, Fatih; Kara, Ahmet; Nedim Alpdemir, M.; Oğuztüzün, Mehmet Halit S. (null; 2009-12-01) In this paper we take a particular stand to the problem of dynamism support in simulation environments by adopting DEVS based modeling and simulation approachand by building upon our previous work on SiMA, a DEVS- based simulation framework developed at TUBITAK UEKAE. Our contribution to the work in this field is two fold: 1 - we have implemented a specialized form of basic DEVS formalism via SiMA (Simulation Modeling Architecture) 2- We have extended SiMA with dynamism support by building upon our speciali...
A comparison of predator teams with distinct genetic similarity levels in single prey hunting problem Yalçın, Çağrı; Şehitoğlu, Onur Tolga; Department of Computer Engineering (2009) In the domain of the complex control problems for agents, neuroevolution, i.e. artificial evolution of neural networks, methods have been continuously shown to offer high performance solutions which may be unpredictable by external controller design. Recent studies have proved that these methods can also be successfully applied for cooperative multi-agent systems to evolve the desired team behavior. For a given task which may benefit from both cooperation and behavioral specialization, the genetic diversity...
Supporting dynamic simulations with Simulation Modeling Architecture (SiMA): a Discrete Event System Specification-based modeling and simulation framework Deniz, Fatih; Alpdemir, M.

DISTRIBUTED 3D DYNAMIC MESH CODING Bici, M. Oguz; Akar, Gözde (2008-10-15) In this paper, we propose a distributed 3D dynamic mesh coding system. The system is based on Slepian and Wolf's and Wyner and Ziv's information-theoretic results. Our system extends the ideas in distributed video coding to 3D dynamic meshes with constant connectivity. The connectivity of the sequence and key frames are encoded and decoded by a conventional static mesh coder. The Wyner-Ziv frames are encoded independent of key frames but decoded jointly with decoded key frames. The joint decoding is perform...
Utilization of feature modeling in axiomatic design Üçtepe, Orhan; Doğru, Ali Hikmet; Department of Computer Engineering (2008) This thesis provides an approach to use feature modeling with a set of guidelines for requirements definition and decomposition activities of the axiomatic design methodology. A tool that supports the development of feature models and modeling of the Axiomatic Design activities is implemented to be utilized for guiding the designer. Axiomatic Design suggested four domains of information in the transformation of the problem definition to the solution, and provided mechanisms for supporting the mapping among ...
