abstract most structural failures are because of break in consisting materials. these breaks are initiated with crack extension, which is a serious threat to the behavior of structure, so different methods have been developed for distinguishing and showing such cracks. meanwhile, the new methods based on original wavelet transform are efficient and very important in the subject of signals. the ...

Purpose – This paper aims to describe a project conducted by the University of Oklahoma Libraries to create a digital collection consisting of three-dimensional scientific objects. Design/methodology/approach – The University of Oklahoma Libraries developed the following methodology for creating a digital collection of three-dimensional objects. Digital still photographs of six sides of each ob...

Quantum transport has far-reaching applications in modern electronics as it enables the control of currents nanoscale systems such quantum dots. In this paper we introduce tinie: a state-of-the-art simulation framework, which can efficiently perform first-principle calculations based on Landauer-B\"uttiker formalism. The computational repertoire tinie includes transmission, conductivity, and ru...

In this paper, a systematic approach is presented for optimal design of tunnel support lining using two-dimensional finite element analysis models of soil-structure interaction developed in ABAQUS software and the Modified Colliding Bodies Optimization (MCBO) algorithm implemented in MATLAB environment. This approach is then employed to study the influence of variable geometrical and geo-mechan...

The dynamical behavior of real-world phenomena is implausible graphically due to the complexity mathematical coding. present article has mainly focused on some one-dimensional real maps’ irrespective using In continuation, linear, quadratic, cubic, higher-order, exponential, logarithmic, and absolute value maps have been used scrutinize their behavior, including characteristics orbit points. Dy...

A number of sculptures have been created based on three-dimensional mathematical forms and surfaces. In most cases, the sculpture is an exact copy of the mathematics that it is based on. This paper explores another method to mathematically create sculptural forms by starting with a two-dimensional figure. The goal is to develop methods and insights on which elements in the original figure can b...

Virtual Synergy is a three-dimensional environment for collaboration between humans, software agents and robots. We have created several tools to enable the use of Virtual Synergy as a viable tool for classroom instruction as well as research work. We have created software to enable robots to work inside of a three-dimensional environment of Virtual Synergy as well as libraries for agent creati...
