We present empirical data on flight speed for 30 species of Australian bats representing seven families. These data show five characteristic level flight speeds: ‘minimum’ (Vmin), ‘best efficiency’ (Veff), ‘most common’ ...

Over the years, grinding has been considered one of the most important manufacturing processes. Grinding is a high precision process, and the loss of a single workpiece in this stage of the production is unacceptable, for ...

Previous bat aerodynamic power models are refined by (1) varying the value of wing profile drag with lift coefficient, which varies with both flight speed and Reynolds number, (2) allowing for the aerodynamic cleanliness ...

In this paper, the fundamentals of a prospective Internet that aims to collect electric charge of virions at streets is presented. The purpose of this paper is twofold: (i) In one hand to demonstrate the capability of ...

A nonlinear analysis is performed on a two-degree-of-freedom wing-based system. Structural nonlinearities are introduced in the pitch degree of freedom when considering two different forms of the aerodynamic loads. Comparisons ...

In this work, the authors present a two-dimensional computational model for predicting the aeroelastic response as well as the output power of vertically arranged harvesters by taking into account all aerodynamic interactions. ...

The effects of the aerodynamic loads on continuous wing-based systems can be represented using a quasi-steady or a fully unsteady reduced-order modeling. Frequently, the quasi-steady formulation is used to model the ...
