DOI: 10.1002/nme.6243
Abstract: Projected reduced order methods (PROM) such as the proper orthogonal decomposition (POD) rely on the quality of the underlying reduced basis (RB) used to approximate the solution. The RB is generally constructed by the low‐rank… read more here.

DOI: 10.1007/s11071-018-4476-7
Abstract: Precise model-based control of parallel robots necessitates an analytically accurate and consolidated model of the robotic platform. Lack of accuracy in modeling causes lots of dynamic uncertainties. This fact can result in higher control gains… read more here.

DOI: 10.1007/s40430-018-1031-x
Abstract: Shot peening is a cold-working process that induces a small indentation on a metallic surface by impacting shots onto it causing residual compressive stresses which delays the initiation of fatigue cracking. The experimental assessment of… read more here.

DOI: 10.1016/j.postharvbio.2019.05.024
Abstract: Abstract A 3D scanner was used to reverse engineer a model to assess impact bruising of fresh Goji (Lycium barbarum L.) fruit. Based on the results of physical compression tests, an elastic-plastic model was selected… read more here.
