In this paper, surface and piezoelectric effects on the vibration behavior of nanowires (NWs) are investigated by using a Timoshenko beam model. The electric field equations and the governing equations of motion for the piezoelectric NWs are derived with the consideration of surface effects. By the exact solution of the governing equations, an expression for the natural frequencies of NWs with ...

In all the production domains, we usually notice a difference between the user's idea and the designer's proposition product. This variable difference often depends of the design process methodology used by the company. Nowadays, more and more surgical interventions are carried out in Minimally Invasive Surgery, to make the post-operative constraints less painful for the patient. New surgical t...

[1] Traveltime determinations have found increasing application in the characterization of groundwater systems. No algorithms are available, however, to optimally design sampling strategies including this information type. We propose a first-order methodology to include groundwater age or tracer arrival time determinations in measurement network design and apply the methodology in an illustrati...

In this work, we present a novel framework that comprises four stages of process modeling and multiobjective decision-makings considering monetary and non-monetary aspects. Four stages in early design phases are considered and characterized by the available information for process modeling and assessment. Appropriate modeling methods, and evaluation indicators for economy, life-cycle environmen...
