OF THE DISSERTATION A Multiobjective Approach for Addressing Dynamism and Heterogeneity in Parallel Scientific Simulations by SUMIR CHANDRA Dissertation Director: Professor Manish Parashar Scientific simulations offer the potential for accurate solutions of realistic models of complex physical phenomena. These simulations are based on systems of partial differential equations and are playing an...

Software development is a constant endeavor to optimize qualities like performance and robustness while ensuring functional correctness. Architecture Description Languages (ADLs) form a foundation for modeling and analyzing functional and non-functional properties of software systems, but, short of programming, only the simulation of those models can ensure certain desired qualities and functio...

The business values of intellectual capital (IntC) and innovation capability (InnoC) are enduring research questions, especially for high-tech firms. Although each one has been recognized as a critical factor for firm’s competitiveness, few studies discussed the influence of IntC and InnoC on firm performance in one integrated framework. Moreover, the moderating effects of environmental dynamis...

a r t i c l e i n f o Some scholars hold that dynamic capability is one of the key in searching for competitive advantage in strategic management. But there are still debates on the definition and effects of dynamic capabilities and the role of environmental dynamism. In the context of Chinese-like emerging economies, from a strategic process perspective, this study defines dynamic capability a...

Secure multicast communication is a significant requirement in emerging applications in adhoc environments like military or public emergency network applications. Membership dynamism is a major challenge in providing complete security in such networks. This paper proposes a efficient Group Based Multicast Hierarchy (GBMH) algorithm for secret multicast communication, in which source nodes used ...

In this paper, we present our approach to introduce dynamism support to simulation environments, which adopts a Discrete Event System Specification (DEVS)-based modeling and simulation approach and builds upon previous work on Simulation Modeling Architecture (SiMA), a DEVS-based simulation framework developed at TUBITAK UEKAE. In the relevant literature there are already proposed solutions to ...

decline in business dynamism is evident in a pronounced declining trend in the pace of both gross job creation and gross job destruction. An important component of these declining trends has been the decline in the firm startup rate. The decline in the startup rate has yielded a significant decline in the share of employment accounted for by young firms – this share has declined by almost 30 pe...

Transition intermediaries are actors that support socio-technical transition processes by bridging structural deficiencies in a transitioning domain. Previous research has identified what roles perform and how. However, while domains definition state of change, the dynamics have hardly been studied. Therefore, we explore mechanisms driving change transition-supportive intermediaries, kind condi...

The computational requirements of applications targeting multiand manycore systems increase rapidly. In order to achieve optimized execution, streaming applications must dynamically adapt to changes of their input. In this work, this intra-application dynamism is explored using an H.264 standard complying Codec pair. Initially, an encoder/decoder pair of applications is implemented for the DAL ...
