Quantum-dot cellular automata (QCA) are an emerging technology and a possible alternative for semiconductor transistor based technologies. A novel fault-tolerant QCA full-adder cell is proposed: This component is simple in structure and suitable for designing fault-tolerant QCA circuits. The redundant version of QCA full-adder cell is powerful in terms of implementing robust digital functions. ...

the graphical technique for nonlinear circuits was described that enable us to optimize circuits to obtain maximum output power, maximum efficiency or minimum intermodulation. according to this method a high power amplifier in the ka band was designed. using a nonlinear model of the transistor, optimum slope for load-line was determined so that maximum power at the output was obtainable, then ...

In order to achieve a comprehensive understanding of complex biological systems, researchers must develop new techniques that incorporate key features of the system across all relevant spatial and temporal scales. Recent advances in molecular biology and genetics have generated a wealth of experimental data that provides details with respect to gene-expression patterns and individual gene and p...

The paper presents a recent development of an interdisciplinary research exploring innovative computational approaches to the scientific study of criminal behavior. The attention is focused on an attempt to combine social network analysis and agent-based modelling into CrimeMiner, an experimental framework that seamlessly integrates document-enhancement, visualization and network analysis techn...

The advent of “distant reading” methods has created the opportunity to look at texts in a new way. But with the shift from close to distant reading, there is also a danger of loosing sight of fine-grained text structure. Like any method, distant reading methodology is not theoretically neutral, but carries a bundle of presuppositions. In this paper, a new method of text network analysis is prop...

Knowledge diffusion takes place over network structures and is also a mechanism of network creation. The use of network analysis techniques and of the ideas coming from recent developments of the theory of complex networks may be of utility to study knowledge diffusion processes among organizational populations. In this work, the network approach is used to analyze the results obtained by an ag...

In this paper, some of the main results of an interdisciplinary research project on standards are presented and integrated into a single framework of technology diffusion. Based on network effect theory and diffusion theory, we present an agent-based simulation model that extends the traditional economical network perspective by incorporating structural determinants of networks (centrality, top...

In recent years, size of VLSI circuits is dramatically grown and layout generation of current circuits has become a dominant task in design flow. Standard cell placement is an effective stage of physical design and quality of placement affects directly on the performance, power consumption and signal immunity of design. Placement can be performed analytically or heuristically. Analytical placer...

ZHENGQI PAN: Global Value Chains and Production Networks: State-Business Relations and Complexity in Economic Crises (Under the direction of Thomas Oatley) The proliferation of global value chains and production networks (GVCs/GPNs) has significantly altered the complexion and complexity of international trade. Much research fervor has been generated to examine the economic organization and spa...
