This paper proposes a topology optimization method for dual-threshold (DT) independent-gate (IG) FinFET circuits. In the proposed method, a node extraction algorithm is developed to extract the characteristic nodes of a BDD expression, which are suitable to be realized with the compact logic gates based on the DT IG FinFET devices, and then the equivalent replacement program that these extracted characteristic...
Regarding optimized logic network generation, recent papers have demonstrated that non-series-parallel topologies can deliver arrangements with fewer transistors when compared to the widely used series-parallel approach. However, due to its topology particularities, this paradigm represents a challenge for physical cell design, especially concerning the transistor placement procedure. In this scenario,...
Threat propagation analysis is a valuable tool in improving the cyber resilience of enterprise networks. As these networks are interconnected and threats can propagate not only within but also across networks, a holistic view of the entire network can reveal threat propagation trajectories unobservable from within a single enterprise. However, companies are reluctant to share internal vulnerability...
Recent works demonstrate constant optimizations in the number of transistors necessary to implement some logic functions by using non-series-parallel arrangements. However, these kind of networks can produce non-dual and non-planar structures, which cannot be fully treated by some of the classical algorithms dedicated to placement. In this paper we present two methodologies to place and route non-series-parallel...
Despite their substantial power savings, voltage scaling design increases the concern about sensitivity to manufacturing process and operating conditions variations. These can induce significant delay changes in fabricated circuits. An elegant approach to cope with these issues is to employ quasi delay-insensitive asynchronous design styles, which allow relaxing timing assumptions, enabling simpler...
MOS planar technology has been used in fabrication of integrated circuits in the last decades. However, the short channel effects in the subthreshold operation region are becoming a critical restriction to the channel length reduction. With the use of FinFET devices, the scaling increases due the reduction of short channel effects. FinFET offers the possibility of independent gate controlling that...
Nowadays, in-vehicle network design has become a difficult challenge due to increased complexity and strict real-time constraints.

It firstly allocates electronic control units (ECU) automatically to one of the CAN buses via...
Frequency spectrum resource is the most important and fundamental resource for various information systems such as communication systems, radar systems and so on.

In this paper, we give a comprehensive work on the problem of how...
A wireless mesh employing directional antenna, termed DMesh in this paper, can greatly extend coverage and improve spatial reuse of wireless channels. As beaming direction of the antennas changes network topology which in turns affects routing and channel decisions, we address in this work how to jointly optimize topology (in terms of beaming directions of antennas), routing and channel assignment...
In the context of networks of massively parallel execution models, optimizing the locality if inter-process communication is a major performance issue. We propose two heuristics to solve a dataflow process network mapping problem, where a network of communicating tasks is placed into a set of processors with limited resource capacities, while minimizing the overall communication bandwidth between...
In this work, we investigate upon the potential of considering the Intelligent Transportation Systems (ITS) for cellular traffic offloading as an alternative to Wi-Fi and femtoCells approaches.

Although having high potential for broadband wireless access, wireless mesh networks are known to suffer from throughput and fairness problems, and are thus hard to scale to large size. To this end, hierarchical architectures provide a solution to this scalability problem. In this paper, we address the problem of design and optimization of a tiered wireless access network. At the lower tier, mesh...
