Surface wind vector measurements over the oceans are vital for scientists and forecasters to understand the Earth's global weather and climate. In the last two decades operational measurements of global ocean wind speeds were obtained from passive microwave radiometers (SSM/I’s); and over this period, full ocean surface wind vector data were obtained from several NASA and ESA scatterometry miss...

Brain-derived neurotrophic factor (BDNF) is known to be crucial for the development of peripheral vestibular neurons. However, the maturation profile of the BDNF signal transducing receptor, tyrosine kinase B (TrkB) in functionally activated otolith-related vestibular nuclear neurons of postnatal rats remains unexplored. In the present study, conscious Sprague-Dawley rats (P4 to adult) were sub...

background and aim: the video head-impulse test (vhit) measures the vestibulo-ocular reflex (vor) driven by each semicircular canal, follo­wing high-acceleration head rotations. the main measurable response is the ratio of eye mov­ement velocity to the angular head velocity, which reflects canal function. although norma­tive data is available for vor gain, most studies only report horizontal vo...

Abstract Horizontal and vertical generating functions recursion relations have been investigated by Comtet for triangular double sequences. In this paper we investigate the horizontal log-concavity of sequences assigned to polynomials which show up in combinatorics, number theory physics. This includes Laguerre polynomials, Pochhammer D’Arcais Nekrasov–Okounkov polynomials.

The need to further exploit offshore wind resources in deeper waters has led to a re-emerging interest in vertical axis wind turbines (VAWTs) for floating foundation applications. However, there has been little effort to systematically compare VAWTs to the more conventional horizontal axis wind turbine (HAWT). This article initiates this comparison based on prime principles, focusing on the tur...

The aim of this research work is to modulate the pitch angle both types wind turbines based on fuzzy logic control (FLC), as changes in have various functions horizontal and vertical axis turbines. For HAWT, applied shield electrical components turbine when speed exceeds rated without shutting down turbine. FLC used angular velocity using two inputs one output with three membership for output. ...
