Stochastic intervals for the family of quadratic maps
Open Research Data
open access
- P. Pilarczyk
- G. Graff
Numerical analysis of chaotic dynamics is a challenging task. The one-parameter families of logistic maps and closely related quadratic maps f_a(x)=a-x^2 are well-known examples of such dynamical systems. Determining parameter values that yield stochastic-like dynamics is especially difficult, because although this set has positive Lebesgue measure,...
Angular welding distortion - one sided fillet weld
Open Research Data
open access
- J. Kowalski
- J. Kozak
- A. Wierzbicka
Welding 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...
