We derive a model for a wind turbine tower in the plane of the turbine blades, which comprises an Euler–Bernoulli beam coupled with a nacelle (rigid body) and a two-mass drive-train model (with gearbox). This model has two possible control inputs: the torque created by the electrical generator and the force created by an electrically driven mass located in the nacelle. First, we consider the ca...

The present work describes the methodology for predicting the behavior of extrapolation curves obtained in radionuclide standardization by 4pb-g coincidence measurements, applied to Na, developed at the Laboratório de Metrologia Nuclear of IPEN-CNEN/SP (LMN–Nuclear Metrology Laboratory). The LMN system consists of a proportional counter (PC) in 4p geometry coupled to a single or a pair of NaI(T...

Chronic equine laminitis causes persistent pain and lameness in affected animals and often necessitates euthanasia when pain management strategies become ineffective. Published studies as well as anecdotal reports suggest that this chronic inflammatory disease is associated with systemic alterations in immune responsiveness, perhaps involving an autoimmune component. We investigated this broad ...

Abstract We test the hypothesis that internal waves observed in flow over forest canopies are generated by Kelvin–Helmholtz instability. The were at night, under stably stratified and weak wind conditions, with a horizontally scanning aerosol lidar an instrumented tower. images used to determine salient wavelength phase propagation velocity of each episode. Time series data measured tower then ...

In the design of DC system, more than one MVU tower may be used between pole-to-neutral voltages. This is especially common for UHVDC systems. The insulation design of these MVU’s need to be verified by dielectric type tests as specified by international standards. However, the application of several MVU’s in series makes the test set-up complicated. One straightforward solution is to install a...

Salmon genomics is an emerging field that represents a convergence between socially important scientific innovation and a politically volatile topic of significant interest to the public. These factors provide a strong rationale for public input. This report describes such input from a public engagement event based on the principles of deliberative democracy. The event involved a random, demogr...

In this paper, we study the convergence rates of homogenization problems for composites with general stratified periodic structure. After introduced auxiliary function, we get the representation formula satisfied by oscillatory solution and homogenized solution. Then we utilize the formula in combination with the asymptotic estimates of Green functions to obtain convergence rates in p L of solu...

In this paper, we consider double sequence iteration processes for strongly $rho$-contractive mapping in modular space. It is proved, these sequences, convergence strongly to a fixed point of the strongly $rho$-contractive mapping.

In this paper we derive convergence theorems for an -nonexpansive mappingof a nonempty closed and convex subset of a complete CAT(0) space for SP-iterative process and Thianwan's iterative process.
