On the transition from local regular to global irregular #uctuations
We present a general framework for understanding the transition from local regular to global irregular (chaotic) behaviour of nonlinear dynamical models in discrete time. The fundamental mechanism is the unfolding of quadratic tangencies between the stable and the unstable manifolds of periodic saddle points. To illustrate the relevance of the presented methods for analysing globally a class of...
متن کاملTransition Radiation Spectra of Electrons from 1 to 10 GeV/c in Regular and Irregular Radiators
We present measurements of the spectral distribution of transition radiation generated by electrons of momentum 1 to 10 GeV/c in different radiator types. We investigate periodic foil radiators and irregular foam and fiber materials. The transition radiation photons are detected by prototypes of the drift chambers to be used in the Transition Radiation Detector (TRD) of the ALICE experiment at ...
متن کاملDeformable texture : the irregular-regular-irregular cycle
Departures from a regular texture pattern can happen in many di erent dimensions. Previous related work has focused on faithful texture synthesis for near-regular texture departing along the color and intensity axes while the underlying geometric regularity is well preserved. In this paper, we address the issue of faithful texture synthesis for textures that have both the structural and color/i...
متن کاملFrom Local to Global Consistency* from Local to Global Consistency*
In reasoning tasks involving the maintenance of consistent databases (so called "constraint net works") it is customary to enforce local consistency conditions in order to simplify the construc tion of a globally coherent model of the data. In this paper we present a relationship between the sizes of the variables' domains and the level of local consistency sufficient to ensure global con si...
متن کاملTransition from First Drug Use to Regular Injection among People Who Inject Drugs in Iran
Background: The study aimed to evaluate the interval between first drug use and regular injection and factors associated with transition from first injection into premature regular injection among people who inject drugs (PWIDs).Methods: In a multicenter cross-sectional study, we recruited 400 PWIDs using snowball sampling. Age of first drug use, age of initiation of regular injection, and demo...
