On Irregularities of Distribution

Investigation of Wagon Derailment Moving on Random Rail Irregularities using Nonlinear 3-Dimentional Model (RESEARCH NOTE)

Rail irregularity is one of the most effective factors in train derailment. theste irregularities have generally random distribution that are assumed to be stationary random and ergodic processes in space, with Gaussian amplitude probabiliy densities and zero mean values. The quality of irregularities, their distribution along the rails and wagon speed are the main factors for train derailment ...

Mechanical Properties of Irregular Fiber (Invited Review Paper)

Irregularities are inherent to virtually all fibers, including the conventional textile fibers, the high-performance brittle fibers and newly developed nano-fibers. These irregularities can fall into two main categories: dimensional or geometrical irregularity (external) and structural irregularity (internal). For natural fibers such as wool, diameter variation along fiber length is atypical ex...

Assessment of ASCE 41-06 Pushover Procedure in Performance Evaluation of Concrete Vertical Irregular Buildings

Irregular buildings make up a large portion of  urban infrastructure. Presence of irregularities can be due to architectural and  user changes in building stories. Main objective of this article is evaluate seismic performance of structures with vertical irregularities. Seismic responses are obtained by enveloping peak inelastic responses resulting from pushover analyses according to provided p...

Modeling the Tensile Behavior of Fibers with Geometrical and Structural Irregularities

Virtually all fibers exhibit some dimensional and structural irregularities. These include the conventional textile fibers, the high-performance brittle fibers and even the newly developed nano-fibers. In recent years, we have systematically examined the effect of fiber dimensional irregularities on the mechanical behavior of the irregular fibers. This paper extends our research to include the ...

On Roth’s Orthogonal Function Method in Discrepancy Theory

Motivated by the recent surge of activity on the subject, we present a brief non-technical survey of numerous classical and new results in discrepancy theory related to Roth’s orthogonal function method. Communicated by Yukio Ohkubo The goal of this paper is to survey the use of Roth’s orthogonal function method in the theory of irregularities of distribution, which, in a broad sense, means app...
