In this work, arithmetic distribution matching (ADM) is presented. ADM invertibly transforms a discrete memoryless source (DMS) into a target DMS. ADM can be used for probabilistic shaping and for rate adaption. Opposed to existing algorithms for distribution matching, ADM works online and can transform arbitrarily long input sequences. It is shown analytically that as the input length tends to...

Most existing Multi-View Stereo (MVS) algorithms employ the image matching method using Normalized Cross-Correlation (NCC) to estimate the depth of an object. The accuracy of the estimated depth depends on the step size of the depth in NCC-based window matching. The step size of the depth must be small for accurate 3D reconstruction, while the small step significantly increases computational co...

Most of the multi-loop analytical calculations in quantum field theories have been dine for socalled single-scale problems. This means that the evaluated integrals are basicaly expressed as numerical constants up to a trivial scale factor. Examples of such problems include almost all renormalization group calculations, evaluations of the critical exponents, anomalous magnetic moments of the ele...

The increased power of small computers makes the use of parameter estimation methods attractive. Such methods have a number of uses in analytical chemistry. When valid models are available, many methods work well, but when models used in the estimation are in error, most methods fail. Methods based on the Kalman filter, a linear recursive estimator, may be modified to perform parameter estimati...

The design of Nt -section matching transformer operating at Nt arbitrary frequencies using the particle swarm optimization (PSO) method is presented. Although analytical methods based on standard transmission line theory can be used in such designs, however, the analysis becomes cumbersome if Nt exceeds two, and numerical methods should be used to solve the resulting nonlinear equations. The de...

In this work, we explore the existence of spoof surface plasmons (SSPs) supported by deep-subwavelength high-contrast gratings (HCGs) on a perfect electric conductor plane. The dispersion relation of the HCGs-based SSPs is derived analyt- ically by combining multimode network theory with rigorous mode matching method, which has nearly the same form with and can be degenerated into that of the S...

The mode-matching technique is deployed in this paper in order to analyze and design a substrate integrated waveguide (SIW) T-junction diplexer in Ku-band. The diplexer has bandwidths of 4.12% and 3.79% at 14.55 and 15.85 GHz, respectively. Also in Ku-band, an SIW corner filter is analyzed and designed with the same technique. Analytical results are compared with simulated data obtained from co...
