The paper studies a unit cell mismatch scrambling method for high-resolution unary DAC based on virtual 3-dimensional (3D) layout, to improve its spurious-free dynamic range (SFDR) communication applications. This can be implemented with relatively simple interconnections and circuits, compared that the 2-dimentional (2D) layout.

Dielectric responces of the one-dimentional electron system is investigated numerically. We treat an interacting one-dimentional spinless fermion model with disorder by using the Density Matrix Renormalization Group(DMRG) method which is extended for nonuniform systems. We apply an electric field E to the system and calculate dielectric responces. Dielectric responce of the Mott insulator and t...

In this paper, we propose a new genetic algorithm based on the two-dimensional encoding method. Appropriate two-dimensional crossover and mutation operations are designed based on the two-dimensional representation to generate the next generations. A twodimensional repairing mechanism is also proposed to adjust infeasible chromosomes into feasible ones. Experiments are finally made to show the ...

In the previous chapter the work is done using one dimensional Poisson’s equation. The work is extended in order to develop better understanding aspects of the submicronic device to be used as PD. The chapter starts with discussion on the existing theoretical models and their limitations which stimulate to propose the new physics based 2D model. The chapter is divided into four sections. Sectio...

Building 3-dimensional (3D) molecules is the starting point in molecular modeling. Conformer search and identification of a global energy minimum structure are often performed computationally during spectral analysis of data from NMR, IR, and VCD or during rational drug design through ligand-based, structure-based, and QSAR approaches. I herein report a convenient script that allows for automat...

Motion perception is one of the mod important aspect of the biological visual system, @om which we get a lot of infort?tation of the natural world. From the physiological and anatomical study on biological vision system, it is shown tliat the perception of two dimentional (20) t?rotion is in two steps: one dimentional (ID) motion detection arid I D motion information fusion. This paper we pay a...

In this work we consider symplectic Runge Kutta Nyström (SRKN) methods with three stages. We construct a fourth order SRKN with constant coefficients and a trigonometrically fitted SRKN method. We apply the new methods on the two-dimentional harmonic oscillator, the Stiefel-Bettis problem and on the computation of the eigenvalues of the Schrödinger equation.
