The so-called synthesis problem for nets which consists in deciding whether a given automaton is isomorphic to the case graph of a net and then constructing the net has been solved for various type of nets ranging from elementary nets to Petri nets. Though P/T nets admits polynomial time synthesis algorithms, the synthesis problem for elementary nets is known to be NP-complete. Applying the pri...

Intrinsic Physical Unclonable Functions or PUFs have been introduced as a highly secure method to extract digital identifiers and keys from integrated circuits. In the setting of reconfigurable devices, like FPGAs, they can be used to protect the IP contained in the design in a cost-effective and tamper-evident way. In this work, a new type of PUF construction for reconfigurable devices is intr...

The fuzzy flip-flop based multilayer perceptron, named Fuzzy Neural Network, FNN is proposed for function approximation. In recent years much effort has been made for the development of a special kind of bacterial memetic algorithm for optimization and training of the fuzzy neural network parameters. In this approach the FNN parameters have been encoded in a chromosome and participate in the ba...

In our previous work we proposed a Multilayer Perceptron Neural Networks (MLP NN) consisting of fuzzy flipflops (F3) based on various operations. We showed that such kind of fuzzy-neural network had good learning properties. In this paper we propose an evolutionary approach for optimizing fuzzy flip-flop networks (FNN). Various popular fuzzy operation and three different fuzzy flip-flop types w...

The relationship between magnetic order and ferroelectric properties has been investigated for MnWO4 with a long-wavelength magnetic structure. Spontaneous electric polarization is observed in an elliptical spiral spin phase. The magnetic-field dependence of electric polarization indicates that the noncollinear spin configuration plays a key role for the appearance of the ferroelectric phase. A...

The dynamics of the flip-flop motion of single buckled dimers of Si(100) was elucidated by locating the tip of a scanning tunneling microscope over a single flip-flopping dimer and measuring the tunneling current (time trace). Based on a statistical analysis of the time trace, we succeeded in estimating the activation energy and the energy splitting between the two stable configurations of buck...

Equivalence checking tools often use a flip-flop matching step to avoid the state space traversal. Due to sequential optimizations performed during synthesis (merge, replication, redundancy removal, . . . ) and don’t care conditions, the matching step can be very complex as well as incomplete. If the matching is incomplete, even the use of a fast and efficient SAT solver during the combinationa...

of BDDbased 32-bit CRC encoder and decoder using LFSR methodology, with low power and less area. Generally 32-bit CRC is used in Ethernet frame for fault recognition at the transmitted data. The functional required for LFSR implementation is shift registers, flip flop which works for high frequency and yields less delay and consumes less power, the TSPC flip flop which is suitable for high spee...

Most biological membranes possess an asymmetric transbilayer distribution of phospholipids. Endogenous enzymes expend energy to maintain the arrangement by promoting the rate of phospholipid translocation, or flip-flop. Researchers have discovered ways to modify this distribution through the use of chemicals. This review presents a critical analysis of the phospholipid asymmetry data in the lit...
