Infrared thermography based seepage and erosion detection in earthen dams using laboratory scale models
The small patch of seepage is observed near the downstream face as soon as the reservoir on the upstream face is filled to the required head. The volumetric water contents near three locations within the bund, marked as 1, 2, and 3, were measured…

On the second gradient nonlinear spectral constitutive modelling of viscoelastic composites reinforced with stiff fibers
In this Section, we give results for two boundary value problems, the pure bending of a slab and the extension and inflation of a solid cylinder, where their deformations are prescribed. We note that, up to our current knowledge, we believe that…

Energy consumption prediction of PEVs incorporating traffic flow information
Structure of the algorithm
In conventional energy consumption prediction method, the average of \(ECR_{b}\) over a past period of time is usually used as a proxy for future \(ECR_{b}\)
$$EC_{b}^{pred} = ECR_{b}^{pred} \times x_{future} \approx…
