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...
In this paper, we use stimulated Raman adiabatic passage technique to implement single-qutrit quantum gates in tripod systems. It is shown by using the Morris-Shore (MS) transformation, the six-state problem with 5 pulsed fields can be reduced to a basis that decouples two states from the others. This imposes three pulses not connected to the initial condition with have the same shape. Using th...
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...
Traditional cost-benefit analysis (CBA) quantifies the value of information security safeguards in terms of their expenses compared to their savings before and after their implementation. This paper considers CBA from the attacker's viewpoint, adding another type of measurement, the willingness to endure consequences. We propose a new set of equations and examine their implications vis-à-vis tw...
hydraulic simulation of water flow in irrigation canals may reveal management shortcomings and help managers find solutions to them. hydraulic simulation models can be appropriate tools for understanding hydraulic behavior of irrigation systems. in the present study, the steady state hec-ras model was tested and compared with the mike 11 unsteady state model. a secondary irrigation canal in the...
The electrical properties and rectification behavior of the graphene self-switching diodes by side gates doping with nitrogen and boron atoms were investigated using density functional tight-binding method. The devices gates doping changes the electrical conductivity of the side gates and the semiconductor channel nanoribbons. As a result, the threshold voltage value under the forward bias is s...
Accurate delay calculation of circuit gates is very important in timing analysis of digital circuits. Waveform shapes on the input ports of logic gates should be considered, in the characterization phase of delay calculation, to obtain accurate gate delay values. Glitches and their temporal effect on circuit gate delays should be taken into account for this purpose. However, the explosive numbe...
Introduction: Cleaning and shaping of the root canal system with an efficient and safe technique are the major goals of root canal treatment. The aim of this study was to compare the conventional root canal preparation technique by hand instruments and Gates Glidden drills with ProTaper Universal Rotary system on the root susceptibility to vertical fracture. Methods: Thirty extracted human man...
the usage of turbochargers in diesel engines has led to the downsizing of the motors as well as usage of the waste gates in turbochargers. any dimensional reduction in turbochargers and appurtenant leads to an enhancement on the performance of internal combustion engines and in environmental problems in terms of aerodynamic, thermodynamic and mechanical specifications for both engines and turbo...
residual microorganisms in the root canal system (rcs) after endodontic therapy such as candida albicans are a major cause of endodontic failure. calcium hydroxide (ch) and chlorhexidine (chx) have suitable antimicrobial activity against bacteria and can be used as intracanal medicaments. nanosilver has also shown antimicrobial activity against microorganisms. this study aimed to compare the an...
