• #### Electronic Textbook of Electromagnetic Waves ﻿

Teaching university courses, which deal with the phenomena of the electromagnetic (EM) substantiality and their applications, is rather difficult due to their abstract nature. Therefore, teaching has to be accompanied by ...
• #### Wireless LAN Network Design: Site Survey or Propagation Modeling? ﻿

There are two basic ways to deploy wireless LAN access points in an indoor scenario: manual deployment using a site survey based on empirical measurements or planning using a software tool with built-in signal propagation ...
• #### Comparative Evaluation of UMTS, WLAN, BWA, MBWA, and UWB Systems ﻿

UMTS, WLAN, BWA and UWB systems are compared in this paper. The comparative analysis covers system capacity, QoS, and radiowave propagation.
• #### Compatibility of Data Transfer between CAD Applications ﻿

Compatibility of data transfers between individual CAD programs is topical when in another program we need to use a drawing or a 3D model created in a program that uses a different modeling kernel. The paper characterizes ...
• #### Clear-Air Propagation Modeling using Parabolic Equation Method ﻿

Propagation of radio waves under clear-air conditions is affected by the distribution of atmospheric refractivity between the transmitter and the receiver. The measurement of refractivity was carried out on the TV Tower ...
• #### Modification of Ordinary Differential Equations MATLAB Solver ﻿

Various linear or nonlinear electronic circuits can be described by the set of ordinary differential equations (ODEs). The ordinary differential equations can be solved in the MATLAB environment in analytical (symbolic ...
• #### Modeling of Imaging Systems in MATLAB ﻿

For many applications in image processing it is necessary to know model of imaging system, which has been used for image data obtain. Knowledge about system can be used for the simulation of an image data in astronomy ...
• #### Statistics of Radio Refractivity Derived from Prague Radiosounding Data ﻿

Vertical gradient of radio refractivity in the lowest 100 m is derived from the meteorological radio-sounding data of the Prague-Libus station. The data cover the measurements at the terms 00, 06, 12, and 18UTC, and the ...
• #### Utilization of MATLAB for Digital Image Transmission Simulation., ﻿

The paper deals with the utilization of Matlab for simulation and analysis of the digital image transmission and transmission distortions in DTV (Digital Television) and DVB (Digital Video Broadcasting) area. The simulation ...
• #### An Accuracy Comparison of the Digital Filter Poles-Zeros Analysis ﻿

In the paper, a comparison of MATLAB and CIA procedures for computing the poles and zeros of digital filters is performed. The accuracy of both tools is tested using finite impulse response filters of a higher order - the ...
• #### Using MATLAB for Analysis of TRAP System ﻿

This article describes a Matlab function for reading and processing file outputs from a structure of classifiers. These classifiers - neural nets - are used in speech recognition based on temporal trajectories (TRAP) of ...
• #### Utilization of MATLAB in Simulation of Linear Hybrid Circuits ﻿

In the paper a MATLAB-based method for simulating transient phenomena in linear hybrid circuits containing parts with both lumped and distributed parameters is presented. Distributed parts of the circuit are multiconductor ...
• #### Mobile Radio Channels Modeling in MATLAB ﻿

In this paper, a MATLAB based approach for mobile radio channels modeling is presented. Specifically, the paper introduces the basic concepts for modeling flat fading channels in MATLAB by means of user-defined m-files. ...
• #### A Computer Simulation of Ultrasound Thermal Bio-Effect in Embryonic Model ﻿

At the present time, the usage of ultrasound diagnostic equipment has become an inseparable part of diagnosis for a number of medical investigations. Several scientific studies published in the last years showed that when ...
• #### Modeling the Substrate Skin Effects in Mutual RL Characteristics., ﻿

The goal of this work was to model the influence of the substrate skin effects on the distributed mutual impedance per unit length parameters of multiple coupled on-chip interconnects. The proposed analytic model is based ...
