Georges Perec's La Vie mode d'emploi ( Life: A User's Manual) was famously based on a number of meticulously crafted lists, including list errors that should be made in the writing each chapter. The engagement with imperfection novel is central way it balances structure and composition random exchangeable elements throughout his work plays significant role. In this article, I will move from to ...

We consider quasi-perfect codes in Z over the `p metric, 2 ≤ p <∞. Through a computational approach, we determine all radii for which there are linear quasi-perfect codes for p = 2 and n = 2, 3. Moreover, we study codes with a certain degree of imperfection, a notion that generalizes the quasi-perfect codes. Numerical results concerning the codes with the smallest degree of imperfection are pre...

The unfolding due to imperfections of a gluing bifurcation occurring in a periodically forced Taylor–Couette system is analyzed numerically. In the absence of imperfections, a temporal glide-reflection Z2 symmetry exists, and two global bifurcations occur within a small region of parameter space: a heteroclinic bifurcation between two saddle two-tori and a gluing bifurcation of three-tori. As t...

This paper presents a joint imperfection detection method for on-line process monitoring of laser brazing processes. The method uses images from two spectral ranges and fuses their features with the scores of the separately calculated log-likelihood ratios to decide whether the currently generated part of a joint contains an imperfection or not. To avoid unconfident classifications, a decision ...
