The On-line Evolutionary Method for Soft Fault Diagnosis in Diode-transistor Circuits

The paper is devoted to diagnostic method enabling us to perform all the three levels of fault investigations, it means, detection, localization and identification. It is designed for analog diode-transistor circuits, in which the circuit state is defined by DC sources values causing elements operating points and the harmonic components with small amplitudes being calculated in accordance with small signal circuit analysis rules. Gene expression programming (GEP), differential evolution (DE) and genetic algorithms (GA) are a mathematical background of the proposed algorithms. Time consumed by diagnostic process rises rapidly with the increasing number of possible faulty circuit elements in case of using any of mentioned algorithms. Use of two different circuit models with partly different elements allows us to decrease a number of possibly faulty and possibly concurrently faulty elements in all of them, and results in an increasing number of measurement points. This significantly increases probability of creating conditions for carrying out an effective on-line circuit testing, without necessity of performing additional simulations

A verification technique for multiple soft fault diagnosis of linear analog circuits

The paper deals with multiple soft fault diagnosis of linear analog circuits. A fault verification method is developed that allows estimating the values of a set of the parameters considered as potentially faulty. The method exploits the transmittance of the circuit and is based on a diagnostic test leading to output signal in discrete form. Applying Z-transform a diagnostic equation is written which is next reproduced. The obtained system of equations consisting of larger number of equations than the number of the parameters is solved using appropriate numerical approach. The method is adapted to real circumstances taking into account scattering of the fault–free parameters within their tolerance ranges and some errors produced by the method. In consequence, the results provided by the method have the form of ranges including the values of the tested parameters. To illustrate the method two examples of real electronic circuits are given

Biological properties of surface layers for ring of heart valve application

Oryginalna sztuczna komora wspomagania serca POLVAD opracowana w Polsce, została zastosowana dotychczas w leczeniu ponad 210 pacjentów. Najdłuższe wspomaganie serca za pomocą komory POLVAD trwało ponad rok. Dla protezy tej opracowywana jest innowacyjna zastawka dyskowa, z nisko profilowym pierścieniem wykonanym ze stopu tytanu. Dla zminimalizowania trombogenności pierścienia zastawki opracowano dyfuzyjne warstwy powierzchniowe: azotowaną typu TiN+Ti2N+αTi(N) i tlenoazotowaną typu TiO2+TiN+Ti2N+αTi(N), wytwarzane obróbką jarzeniową na potencjale plazmy. Trombogenność różnych kompozycji warstw została porównana w aspekcie aktywacji i adhezji płytek krwi do powierzchni biomateriału. Oceniono również wpływ metody sterylizacji biomateriału na intensywność adhezji trombocytów do jego powierzchni. Warstwy TiN oraz TiO2wykazały najniższą trombogenność, przy czym dla warstwy TiN korzystniejsza jest sterylizacja gazowa, podczas gdy dla warstwy TiO2- sterylizacja plazmowa.The original ventricular assist device POLVAD developed in Poland was used in over 210 patients so far. The longest POLVAD heart assistance excided one year. The innovative tilting disk valve with low profile ring made of titanium is developed for POLVAD. To minimize the valve ring thrombogenicity the diffusive surface layers were manufactured: nitriding TiN+Ti2N+αTi(N) and oxynitriding TiO2+TiN+Ti2N+αTi(N), in the glow discharge process on the plasma potential level. The thrombogenicity of different layers compositionwas compared regarding platelets activation and platelets adhesion to the material surface. The influence of material sterilization method on the platelets adhesion intensity was evaluated in addition. The nitriding TiN and oxynitriding TiO2layers have demonstrated the lowest thrombogenicity while the gas sterilization was the most profitable for nitriding layers – TiN and the plasma sterilization for oxynitriding layers – TiO2

The paper presents the methodology and partial results of an empirical study on the professionalization and mediatization of the local government election campaign from the perspective of its coverage by the regional press. The study was conducted by a research team from four academic centers in Poland, under a research project entitled The elections to local governments in regional media. Regional dailies and television election programs as platforms of political communication. One of the aims of the project was to analyze how election campaigns were covered by local press at the time of the local government election campaign in Poland in 2010. Quantitative and qualitative methods of analysis were applied to the content of press releases concerning the elections collected over the last two weeks of the election campaign, prior to the elections of 21st November 2010, in the regional issues of the printed versions of “Gazeta Wyborcza” and regional variations of the “Polska The Times”, published in four regional capitals – Katowice, Kraków, Poznań and Warsaw. In the case of newspapers, an examined entity was a press release on the elections.The paper presents the methodology and partial results of an empirical study on the professionalization and mediatization of the local government election campaign from the perspective of its coverage by the regional press.

Comparing Genetic Variation among Latin American Immigrants: Implications for Forensic Casework in the Arizona- and Texas-México Borderlands

The humanitarian crisis on the United States-México border is a long standing and evolving crisis in which nearly 8,000 deaths have been reported in the last two decades. These deaths are largely distributed across the Arizona-México and Texas-México border regions where demographic trends for immigrants attempting to cross into the U.S. have shifted dramatically. The demographic change and volume of immigrants seeking shelter in the U.S. presents new challenges for the forensic practitioners entrusted with the identification of individuals who lose their lives during the final segment of their journey. Within this Border context, the present study investigates how genetic variation inferred from forensically significant microsatellites can provide valuable information on regions of origin for unidentified remains on the group level. To explore how we can mobilize these genetic data to inform identification strategies, we conduct a comparative genetic analysis of identified and unidentified immigrant cases from the Arizona- and Texas-México contexts, as well as 27 other Latin American groups. Allele frequencies were utilized to calculate FST, and relationships were visually depicted in a multidimensional scaling plot. A Spearman correlation coefficient analysis assessed the strength and significance of population relationships and an agglomerative clustering analysis assessed population clusters. Results indicate that Arizona-México immigrants have the strongest relationship (\u3e80%) with groups from El Salvador, Guatemala, México, and an indigenous group from Southern México. Texas-México immigrants have the strongest relationships (\u3e80%) with groups from Belize, Colombia, Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. These findings agree with, and are discussed in comparison to, previously reported demographic trends, population genetics research, and population history analyses. We emphasize the utility and necessity of coupling genetic variation research with a nuanced anthropological perspective for identification processes in the U.S-México border context
