Hardened Steel Surface Waviness Created by Rolling Burnishing Process
PublikacjaThe surface of the finishing machined parts is defined mainly by roughness parameters. Growing demands on the part, especially mating sliding or rolling, require the specification of additional parameters, such as waviness parameters, particularly when there is significant resistance to seizing or noise reduction. This paper presents surface waviness characteristics of hardened burnished steel.

Effect of the let-through energy of overcurrent protective devices on the temperature of conductors during short-circuits
PublikacjaThe scope of the verification of low-voltage systems covers the earth fault loop impedance measurement. This measurement is usually performed with the use of low-value current meters, which force a current many times lower than the one occurring during a real short-circuit. Therefore, the international standard recommends consideration of the increase of resistance of conductors with the increase of temperature, which may occur...

A Web-GIS tool for diagnosing spatial orientation of young adults: design and evaluation of Geo-Survey
PublikacjaSpatial orientation is the effectiveness with which one is able to assess the mutual location of objects relative to a point of reference or a system of coordinates. Traditionally, this ability has been evaluated through field navigation tests, which do not take into account the prevailing influence of free online maps and virtual walks on a person’s interpretation of space. In this context, this study presents a Web-GIS tool designed...

The Main Buildings of Technical Universities in Lviv, Warsaw, Gdańsk and Wrocław. Neo-Renaissance „Architecture parlante”
PublikacjaThe article compares the buildings of historical campuses of four technical universities located in areas related to Polish culture. At the turn of the 19th and 20th centuries, several new technical universities were established in Central and Eastern Europe. In 1844, the Technical Academy was opened in Lviv. In 1899, the Russian who were occupying the east and central part of Poland established the Polytechnic Institute in Warsaw....

Low-Voltage LDO Regulator Based on Native MOS Transistor with Improved PSR and Fast Response
PublikacjaIn this paper, a low-voltage low-dropout analog regulator (ALDO) based on a native n-channel MOS transistor is proposed. Application of the native transistor with the threshold voltage close to zero allows elimination of the charge pump in low-voltage regulators using the pass element in a common drain configuration. Such a native pass transistor configuration allows simplification of regulator design and improved performance,...

A theoretical framework for understanding trust and distrust in internet voting
PublikacjaEach and every case of success and failure in the implementation of internet voting is permeated by a common element: the concept of trust. Several researchers highlighted the relevance of creating trust for the successful implementation of technology [15] and, in particular, of internet voting [13]. But the concept itself is complex and challenging to define, for one fundamental reason: it is a concept of everyday social use...
