New IIR digital differintegrators (differentiator and integrator) with very minor absolute relative errors are presented in this paper. The digital integrator is designed by interpolating some of the existing integrators. The optimum value of the interpolation ratio is obtained through linear programming optimization. Subsequently, by modifying the transfer function of the proposed integrator a...

We propose an efficient protocol for digital quantum simulation of quantum chemistry problems and enhanced digital-analog quantum simulation of transport phenomena in biomolecules with superconducting circuits. Along these lines, we optimally digitize fermionic models of molecular structure with single-qubit and two-qubit gates, by means of Trotter-Suzuki decomposition and Jordan-Wigner transfo...

In this article a new algorithm is developed for optimizing computationally expensive simulation models. The optimization algorithm is developed for continues unconstrained single output simulation models. The algorithm is developed using two simulation optimization routines. We employed the nested partitioning (NP) routine for concentrating the search efforts in the regions which are most like...

Computer graphics offer various gadgets to enhance the reconstruction of high-order statistics that are not correctly addressed by the two-point statistics approaches. Almost all the newly developed multiple-point geostatistics (MPS) algorithms, to some extent, adapt these techniques to increase the simulation accuracy and efficiency. In this work, a scrutiny comparison between our recently dev...

A new lock detection algorithm for digital quadrature phase-shift keying (QPSK) receiver is proposed. Analysis of the detector’s output characteristics is given and is verified by using computer simulation. Performance degradation due to carrier jitter is also considered. Analytic and simulation results show that the proposed algorithm is very useful as a lock detector in digital receivers beca...

The digital factory concept offers an integrated approach to enhance products and production engineering processes. Simulation is a key technology within this concept. Different types of simulation, such as discrete event or 3D-motion simulation can be applied in virtual models to various planning tasks and stages to improve the product and process planning at all levels. The focus and key fact...

Logic-level simulation is still one of the most often used operations on digital designs during both design and test stages. This makes it a critical issue affecting the overall cost of a project. In this paper we investigate and show the origins of common advantages of four recently proposed efficient simulation methods of different classes: logic simulation, multi-valued simulation, timing si...

For the Pre-Processor System of the ATLAS Level-1 Calorimeter Trigger we have built a fast signal-processing and readout ASIC (PPrAsic). The novel ASIC design environment incorporates algorithm development with digital hardware synthesis and verification. The purely digital ASIC was designed in Verilog HDL (hardware description language) and embedded in a system wide analog and digital simulati...

During the past fifty years the world has changed and simulation has advanced out of all recognition. The author has progressed from very large analogue computers in the early 1960s, through hybrid analogue/digital systems in the late 60s, to design and construction of digital signal processing computers in the 70s, onto early microcomputers in the 80s, used for simulation, and more recently to...
