How to reconfigure a logic gate for a variety of functions is an interesting topic. In this paper, a different method of designing logic gates are proposed. Initially, due to the training ability of the multilayer perceptron neural network, it was used to create a new type of logic and full adder gates. In this method, the perceptron network was trained and then tested. This network was 100% ac...

Gates are a new notation for representing mixture models and context-sensitive independence in factor graphs. Factor graphs provide a natural representation for message-passing algorithms, such as expectation propagation. However, message passing in mixture models is not well captured by factor graphs unless the entire mixture is represented by one factor, because the message equations have a c...

in this paper a novel all-optical logic nand, nor and xor gate based on nonlinear directional coupler theory is demonstrated. we use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. in other words, while a beam with 4 w/μm in power considered as logical one, the output is nand gate and if a beam w...

In this paper, we have proposed a new design technique of BCD Adder using newly constructed reversible gates are based on NMOS with pass transistor gates, where the conventional reversible gates are based on CMOS with transmission gates. We also compare the proposed reversible gates with the conventional CMOS reversible gates which show that the required number of Transistors is significantly r...

The ubiquitous Catalan numbers Cn = (2n n ) / (n + 1) occur as t (n,−n) in the following table showing the number of ways to reach the point (n,m) on a rectangular grid under certain traffic restrictions, indicated by arrows. m 1↑→ 3↑→ 6↑→ 9↑→ 12↑→ 12↑→ 12↓→ ↘ 2 1↑→ 2↑→ 3↑→ 3↑→ 3↓→ ↘ 12↓→↘ 1 1↑→ 1↑→ 1↓→ ↘ 3↓→↘ 3↓→↘ 12↓→↘ start here 1↑→gate ↘ 1↓→↘ 1↓→↘ 3↓→↘ 6↓→↘ 15↓→↘ −1 ≈ 1 →↘ 1↓→↘ 2↓→↘ 4↓→↘ 9↓...

This paper addresses predicting the impact of access gates on pedestrian flow operations in terms of levels-of-service, congestion levels, average walking times, delays incurred at the gates, etc. To tackle the problem at hand, pedestrian traffic operations for different station design alternatives are predicted using the microscopic pedestrian flow model NOMAD. This is done for reference situa...
