Surface instability of icicles.
Quantitatively unexplained stationary waves or ridges often encircle icicles. Such waves form when roughly 0.1-mm-thick layers of water flow down an icicle. These waves typically have a wavelength of about 1 cm, which is independent of external temperature, icicle thickness, and the volumetric rate of water flow. In this paper, we show that these waves cannot be obtained by a naive Mullins-Seke...
متن کاملExperiments on the morphology of icicles.
Icicles form when cool water drips from an overhanging support under ambient conditions which are below freezing. Ice growth is controlled by the removal of latent heat, which is transferred into the surrounding air via a thin film of water flowing over the ice surface. We describe laboratory experiments in which icicles were grown under controlled conditions. We used image analysis to probe th...
متن کاملBent and generalized bent Boolean functions
In this paper, we investigate the properties of generalized bent functions defined on Z2 with values in Zq , where q ≥ 2 is any positive integer. We characterize the class of generalized bent functions symmetric with respect to two variables, provide analogues of Maiorana–McFarland type bent functions and Dillon’s functions in the generalized set up. A class of bent functions called generalized...
متن کاملSpecial bent and near-bent functions
Starting from special near-bent functions in dimension 2t − 1 we construct bent functions in dimension 2t having a specific derivative. We deduce new families of bent functions.
متن کاملAround bent and semi-bent quadratic Boolean functions
The maximum length sequences, also called m-sequences, have received a lot of attention since the late sixties. In terms of LFSR synthesis they are usually generated by certain power polynomials over finite field and in addition characterized by a low cross correlation and high nonlinearity. We say that such sequence is generated by a semi-bent function. Some new families of such function, repr...
