Rotational Seismology caused highly interest in investigation of rotational movements generated by earthquake, mines and existing in engineering structures. The most oppressive aspect of research in this field is technical requirements for sensors. However, the instruments basing on the Sagnac effect seem to be the most appropriate to investigate rotational effects due to the fact that they are entirely...
The article presents the theme of stereoscopic images quality assessment. The first part of the paper describes the definition of stereoscopy and provides a preliminary discussion of the issue. The second part of the paper lists a set of commonly used metrics for the evaluation of 3D image divided into subjective and objective metrics, and these in turn, based on the analogical 2D metrics and metrics...
Cubic boron nitride is commonly used as a cutting tools material for the sake of its high hardness and wear-resistance. Pulse Plasma Sintering was proposed to decrease the production costs. This method is very attractive for industry, because it significantly decreases the costs of production. The goal of this paper is to present the control system prototype for Pulse Plasma Sintering processes based...
This article presents methodology of simple model building for risk stratification of sudden cardiac death based on an original ECG signal analysis platform. The method includes the analysis of the ECG signal, extraction of selected parameters and model optimization for predicting sudden cardiac death.
In this article an on-line student examining system is presented. The system was developed for use in primary and secondary schools in Poland and features a connection fault tolerant examining engine supporting a wide range of possibilities for presenting questions and answers. System was successfully deployed as a part of “e-egzamin” project which took place in September 2011, during its course more...
In this paper is presented further development of ECG signal analysis software system “Cardio” with capability of Deceleration Capacity (DC) assessment. In the first part of the paper the algorithms used for DC assessment are described. In the second part of the paper are presented results of our implementation verification on ECG signals from group of patients. In the third part is presented proposed...
The article describes development process and operation of an advanced web application based on modern, popular frameworks available for J2EE platform. Capabilities of Spring, Hibernate, JSF and Rich Faces are considered based on auction service application.
The aim of the research presented in this paper was to analyze different e-learning solutions and compare them in the field of functionality and standards compatibility. As most popular applications Moodle, WBT and EXE programs have been chosen. The possibility of export/import courses between them has been discussed.
The aim of the research presented in this paper was to test and evaluate the possibility of T-wave alternans (TWA) detection with the use of standard ambulatory ECG monitors. In development work there is proposal of author's advanced method allowing to remove from signal any distortion and disturbances making impossible further analysis.
The article, by describing features of sample application for project management, presents methods of creating graphical interfaces of modern applications that run in web browser environment. Sample program is written with the use of FLEX Framework and some FLEX supporting tools.
This paper presents the idea of convergence of the IT and telecommunication worlds, based on an example application. The program has been developed in Microsoft Visual Web Developer 2008 environment. As one of the aims the possibilities of convergence are being described. The example application allows users to communicate by video conference using soft phone on one side and WWW browser on the other,...
The purpose of this article is to present research into the inspection of software possibilities of using 8-bit Holter monitor in the study of cardiac arrhythmia (virulent ventricular arrhythmia) appearing in the T wave alternans. The first part of the article concentrates on the preparation of the ECG signal for the alternans analysis and the methods used in the analysis. The second part presents...
This paper describes a sample test implementation of an cost effective Voice over IP network. The implementation is currently taking place at Department of Microelectronics and Computer Science in Technical University of Lodz, Poland
