Lightweight or semi-rigid wings as well as textile kites commonly used in Airborne Wind Energy applications have strong aero-elastic deformations during flight. These effects have been investigated in a number of works. Due to the computational complexity of computational fluid dynamics, fast methods rely on simple inviscid methods or pre-computed assumed functional relations for the aerodynami...

This paper presents a novel robust fractional PIλ controller design for flexible joint electrically driven robots. Because of using voltage control strategy, the proposed approach is free of problems arising from torque control strategy in the design and implementation. In fact, the motor's current includes the effects of nonlinearities and coupling in the robot manipulator. Therefore, cancella...

Microgrid control in isolated mode is a highly important subject area. In the present paper, a new method is used for controlling the isolated microgrids. This method was used based on the classification of the microgrids into two groups, namely fast-dynamic (battery and flywheel) and slow-dynamic (diesel generator, electrolyzer, fuel cell). For the microgrid components with fast dynamics, a se...

We study the scattering of two Skyrmions at low energy and large separation. We use the method proposed by Manton for truncating the degrees of freedom of the system from in nite to a manageable nite number. This corresponds to identifying the manifold consisting of the union of the low energy critical points of the potential along with the gradient ow curves joining these together and by posit...

Chaotic internal degrees of freedom of a molecule can act as noise and affect the diffusion of the molecule on a substrate. A separation of timescales between the fast internal dynamics and the slow motion of the centre of mass on the substrate makes it possible to directly link chaos to diffusion. We discuss the conditions under which this is possible, and show that in simple atomistic models ...

background : in this study, we used both its1 and its2 for molecular identification of fasciola species. methods : the region between 18s and 28s of ribosomal dna was used in pcr-rflp method for molecular identification of fasciola species. ninety trematodes of fasciola were collected during abattoir inspection from livers of naturally infected sheep and cattle from khorasan, east azerbaijan, a...
