We give direct experimental evidence for the observation of full transverse self-modulation a long, relativistic proton bunch propagating through dense plasma. The exits plasma with periodic density modulation resulting from radial wakefield effects. show that is seeded by ionization front created using an intense laser pulse copropagating bunch. extends over length following seed point. By varying one order magnitude, we frequency scales expected dependence on density, i.e., it equal to...

Consider a collection of elastic wires folded according to given pattern induced by sequence fractal plane curves. The can act as springs. Therefore it is easy build up corresponding simple oscillators composed the springs clamped at one end and carrying mass opposite end. oscillation periods ordered these are related following power law therefore display structure. each oscillator clearly depend on mechanical properties wire, boundary conditions. there infinitely many possibilities design...

De modo categórico, a indústria da construção civil vem deixando uma alta pegada ecológica, fruto, principalmente, dos materiais empregados e das técnicas adotadas. Neste sentido, torna-se imprescindível endereçarmos nossas atenções ao estudo de alternativas aos métodos convencionais se fazer engenharia. Partindo um viés ecológico socialmente responsável, o presente trabalho coloca em luz as possibilidades utilização do bambu enquanto material construção, realizando, maneira sistemática,...

Este trabalho apresenta um estudo do comportamento mecânico de árvores 2D geradas por geometria fractal sujeitas a momentos ou forças horizontais concentradas nas extremidades livres. O modelo geométrico considerado é o da família autossimilares, seja, aquelas evoluídas partir proporções constantes pré-definidas. Tais definem quantidade ramos filhos cada ramo pai , relação entre os comprimentos e as larguras . Com variação tais parâmetros possível gerar uma infinidade árvores, com diferentes...

The purpose of the present paper is to main applications a new method for determination fractal structure plane curves. It focused on inverse problem, that is, given curve in plane, find its dimension. shown dynamical approach extends characterization as object introducing effects mass density, elastic properties, and transverse geometry. dimension characterizes material objects suggests biological can be much more complete with methodology presented here.
