Residual stresses have become an important player in the field of the structural integrity for many years. Having an exact knowledge of residual stress distributions can be essential in designing the engineering components as unexpected failures are inevitable where such stresses are ignored.  There are many residual stresses measurement techniques including destructive and non-destructive ones...

Longitudinal repeated-measures data have often been visualized with spaghetti plots for continuous outcomes. For large datasets, the use of spaghetti plots often leads to the over-plotting and consequential obscuring of trends in the data. This obscuring of trends is primarily due to overlapping of trajectories. Here, we suggest a framework called lasagna plotting that constrains the subject-sp...

In this paper, we use the modified exp−ψθ-function method to observe some of solitary wave solutions for microtubules (MTs). By treating issues as nonlinear model partial differential equations describing microtubules, were able solve problem. We then found specific evolution equation (NLEE) covering various parameters that are particularly significant in biophysics and nanobiosciences. additio...

We analyze the impact of financial crises on major stock markets from 2000 to COVID-19 pandemic using Fourier series. Analyzing behaviors spectra obtained monthly returns their indices, we identify three global 2015, with different characteristics. In addition, applying Z-test and color-contour plotting method propagations frequencies each index, developments in market around by comparing patte...

In contour milling, to render the machining process more automated with significant productivity without remaining material after machining, a new recovery coefficient was developed. The coefficient was inserted in the computation of contour parallel tool paths to fix the radial depth of cut in the way to ensure an optimized overlap area between the passes in the corners, without residuals. Thu...

Quantitative risk analysis (QRA) of industrial facilities has to take into account multiple hazards threatening critical equipment. Nevertheless, engineering procedures able to evaluate quantitatively the effect of seismic action are not well established. Indeed, relevant industrial accidents may be triggered by loss of containment following ground shaking or other relevant natural hazards, eit...
