A physically based quadratic rheological model for hyperconcentrated flows is tested with experimental data sets. The model includes components describing: (1) Cohesion between particles; (2) viscous friction between fluid and sediment particles; (3) impact of particles; and (4) turbulence. The resulting quadratic formulation of the shear stress is shown to be in excellent agreement with the ex...

The safety of construction workers is always a major concern at construction sites as the construction industry is inherently dangerous with many factors influencing worker safety. Several studies concluded that psychological factors such as workload, organizational relationships, mental stress, job security, and job satisfaction have significant effects on workers’ safety. However, research on...

Purpose This paper seeks to examine how expectations from business analytics (BA) by members of agile information systems development (ISD) teams affect their perceptions and continuous use BA in ISD projects. Design/methodology/approach Data was collected 153 respondents working projects analysed using partial least squares structural equation modelling techniques (PLS-SEM). Findings Perceived...

In an external prestressing system, there is no strain compatibility between the cable and the concrete at every cross-section, the increment of cable strain must be evaluated by taking into account the whole structure, rather than performing the calculation at each section, independently. In this study, a method for the calculation of cable strain, which is based on the deformation compatibili...

and Applied Analysis 3 At resonance levels, ur should be arbitrary, and then we are deducing a nonlinear equation g ur−1 · · ·u0, φ · · · 0. If the equation f implies g, then the compatibility condition is unconditionally satisfied. An equation for which these three steps can be carried out consistently and unambiguously passes the Painlevé test. Equation 1.3 is called the truncated Painlevé ex...

An equation was developed for calculating the time to failure by slow crack growth (SCG) failure in any polyethylene structure. The equation requires the following experimental inputs: (1) the resistance to SCG as measured by the PENT test (ASTM F1473), (2) the stress intensity of the defect from which failure originates, and (3) the temperature. A simple experiment for determining the stress i...
