Angular welding distortion - one sided fillet weld
Dane BadawczeWelding is the basic method of joining ship hull elements during its construction. However, this method of joining structural elements generates shrinks. Shrinks causes deformation of the entire welded structure, both linear and angular. In the shipbuilding industry, there is a tendency to oversize fillet welds, at the design as well as manufacturing...

Od podstawy programowej do standardów kształcenia
PublikacjaWprowadzenie "nowej matury" w prowadzenie nowej matury w 2005 roku zrewolucjonizowało proces rekrutacji na wyższe uczelnie. Szkoły wyższe nie chciały początkowo rezygnować z egzaminów wstępnych, próbując zmienić ich formułę, jednak w 2006 roku Ministerstwo Edukacji ograniczyło możliwości przeprowadzania takich „testów kompetencji” tylko do nielicznych przypadków. Co roku egzamin maturalny zmienia niektóre...

Balance error generated by numerical diffusion in the solution of Muskingum equation
PublikacjaIn the paper the conservative properties of the lumped hydrological models with variable parameters are discussed. It is shown that in the case of the non-linear Muskingum equation the mass balance is not satisfied. The study indicates that the mass balance errors are caused by the improper form of equation and by the numerical diffusion which is generated in the solution. It has been shown that the classical way of derivation...

Ultrawideband transmission in physical channels: a broadband interference view
PublikacjaThe superposition of multipath components (MPC) of an emitted wave, formed by reflections from limiting surfaces and obstacles in the propagation area, strongly affects communication signals. In the case of modern wideband systems, the effect should be seen as a broadband counterpart of classical interference which is the cause of fading in narrowband systems. This paper shows that in wideband communications, the time- and frequency-domain...

Waves in a short cable at low frequencies, or just hand-waving? What does physics say? (Invited paper)
PublikacjaWe address the question of low-frequency signals in a short cable, which are often considered as waves in engineering calculations. Such an assumption violates several laws of physics, but exact calculations can be carried out via linear network theory.
