cally for a given tim equation (ODE) softw an ordinary differential In addition to combinatorial gates, dynamic fault trees use four additional kinds of gates as modeling elements: Sequence Enforcing (SEQ), Functional Dependency (FDEP), Priority And (PAND), and Cold, Warm and Hot Spare (CSP, WSP and HSP). A SEQ gate asserts that component failures can occur only in the order specified by its in...

Abstract We propose VQE circuit fabrics with advantageous properties for the simulation of strongly correlated ground and excited states molecules materials under Jordan–Wigner mapping that can be implemented linearly locally preserve all relevant quantum numbers: number spin up ( ? ) down ? electrons total squared. demonstrate our entangler circuits are expressive already at low depth paramete...

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...

Digital systems are said to be constructed using basic logic gates. These gates are the NOR, NAND, AND, OR, EXOR & EXNOR gates. This paper presents a robust three transistors (3T) based NAND and NOR gates with precise output logic levels, yet maintaining equivalent performance than the existing logic structures. This new set of 3T logic gates are based on CMOS inverter and Pass Transistor Logic...

We show that a set of gates that consists of all one-bit quantum gates (U(2)) and the two-bit exclusive-or gate (that maps Boolean values (x; y) to (x; xy)) is universal in the sense that all unitary operations on arbitrarily many bits n (U(2 n)) can be expressed as compositions of these gates. We investigate the number of the above gates required to implement other gates, such as generalized D...

This paper investigates the relationship between a single-electron gate probability of failure and the random variations affecting its elements. The study focuses on digital logic gates and circuits. Two major implementations are considered: static complementary logic gates and threshold logic gates (TLG). In addition to implementation, the effect of the gate fan-in on the reliability is invest...

Geometric phase that manifests itself in number of optic and nuclear experiments is shown to be a useful tool for realization of quantum computations in so called holonomic quantum computer model (HQCM). This model is considered as an externally driven quantum system with adiabatic evolution law and finite number of the energy levels. The corresponding evolution operators represent quantum gate...

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...

We construct the exchange gate with small elementary gates on the space of qudits, which consist of three controlled shift gates and three ”reverse” gates. This is a natural extension of the qubit case. We also consider a similar subject on the Fock space, but in this case it is not clear what elementary gates are. We present some related problems.
