Evaluation of the power quality from a seawave power farm for different interconnection schemes

2007

In this paper we present an approach to the interconnection of a seawave power farm to the grid The generator type used in the farm is a Permanent Magnet (PM) linear generator driven from the seawaves that generates, therefore, highly distorted emfs. We propose and compare two possible ways to interconnect the farm to the grid. One is based on an approach where for each generator there is a conversion subsystem that permits the direct connection of each generator to the a.c. network, the other one is based on an ac.-d.c. converter that is connected to the generator, the converter is connected to a dc link that can receive the power from every unit and that can supply a dc-ac converter direc…

Multimodal Intraoperative Neuromonitoring in Aneurysm Surgery

2017

Following aneurysmal subarachnoid hemorrhage, the primary goal of treatment is to exclude the vascular malformation from the intracranial circulation, while preserving the parent artery. In unruptured aneurysms, the decision whether to treat or observe the malformation is made on a case-by-case basis. In this regard, the ISUIA (International Study of Unruptured Intracranial Aneurysms) investigators suggested that aneurysm size and location were independent predictors for aneurysm rupture.1 ISUIA examined 1692 patients with cerebral aneurysms with a mean follow-up time of 4.1 years. Rupture rates differed depending on size and location, ranging from 0% in aneurysms <7 mm located in the in…

A Simulation Analysis of VSM Control for RES plants in a Small Mediterranean Island

2020

The paper presents an application of Virtual Synchronous Machine control for managing inverter-interfaced renewable energy sources in a small Mediterranean island not supplied by the main grid. In the proposed analysis, the island's renewables-based generators area assumed interfaced to the grid by voltage source converters with a swing controller and a vector-current controller with two different options for the reference current for regulating the voltage at the Point of Common Coupling and the active power output. The system, modeled in PScad environment, allows to verify the response of the renewables-based generators with VSM control in the presence of a fault in the grid.

Juegos motores para niños y niñas con parálisis cerebral

2015

This paper suggests using motor games with children with functional diversity, specifically, with cerebral palsy. As any other child, those with cerebral palsy should play and learn while playing. The characteristics of these children are described because knowing about them will help to adapt the motor games so that they will take more advantage of the benefits of this methodological tool. This is the reason why here some methodological indications are explained, because if they are taken into account, children with cerebral palsy will be more easily included in the games and will take more profit from them.

Kilohertz and Low-Frequency Electrical Stimulation With the Same Pulse Duration Have Similar Efficiency for Inducing Isometric Knee Extension Torque …

2017

International audience; Objective To test the hypotheses that, as compared with pulsed current with the same pulse duration, kilohertz frequency alternating current would not differ in terms of evoked-torque production and perceived discomfort, and as a result, it would show the same current efficiency.Design A repeated-measures design with 4 stimuli presented in random order was used to test 25 women: (1) 500-microsecond pulse duration, (2) 250-microsecond pulse duration, (3) 500-microsecond pulse duration and low carrier frequency (1 kHz), (4) 250-microsecond pulse duration and high carrier frequency (4 kHz). Isometric peak torque of quadriceps muscle was measured using an isokinetic dyna…

From a bodily-based format of knowledge to symbols. The evolution of human language

2013

Although ontogeny cannot recapitulate phylogeny, a two-level model of the acquisition of language will be here proposed and its implication for the evolution of the faculty of language will be discussed. It is here proposed that the identification of the cognitive requirements of language during ontogeny could help us in the task of identifying the phylogenetic achievements that concurred, at some point, to the acquisition of language during phylogeny. In this model speaking will be considered as a complex ability that arises in two different steps. The first step of competence widely relies on a bodily-based format of knowledge. The second step relies on more abstract meta-representations …

P26-S Left and right motor cortical excitability and relationship to motor functions in healthy adolescents

2019

Background The interhemispheric difference in cortical excitability and its relationship to motor functions is unclear. Aim We examined the relationship between handedness, left and right motor cortex excitability and fine and gross motor functions in adolescence. Methods 28 healthy adolescents (age 16–19 years, 19 girls) were studied. Handedness was determined by the Waterloo Handedness Questionnaire. Motor threshold (MT) of the abductor pollicis brevis was measured on both hemispheres using biphasic stimulation, and on the left hemisphere also with monophasic stimulation. Box and block test (BBT) was used for manual dexterity, line run and standing long jump for gross motor tasks. Spearma…
