New shape control implementations and dynamics studies on the National Spherical Torus eXperiment (NSTX) (Ono et al 2000 Nucl. Fusion 40 557–61) are summarized. In particular, strike point position, X-point height and squareness control, and two new system-identification methods/control-tuning algorithms were put into operation. The PID controller for the strike point was tuned by analysing the...

Fly strike in sheep has been estimated to cost the Australian sheep industry approximately $280m dollars annually (Sackett et al. 2006) as a result of sheep losses, cost of treatment and loss of wool and carcase production and value. Historically Australian sheep producers have surgically removed skin from around the tail (mulesing) to help avoid fly strike. Although this has proved highly succ...

in reporting of wildlife strikes with civil aircraft and in identification of species struck under a primarily Executive Summary Reporting of wildlife strikes with civil aircraft is voluntary for airports and pilots but strongly encouraged by the FAA via Advisory Circulars and other activities. In 2009, the FAA undertook a review of the trends in strike reporting from 1990-2008 to determine if ...

BACKGROUND This study aimed to investigate the relation between key strike forces and musculoskeletal symptoms (MSS). Moreover, this study presents a key strike force measurement method to be used in a workplace setting. The correlation between key strike force characteristics and MSS was previously studied, but the measurement methods used either a single-key switch or force platforms applied ...

[1] Motivated by observations in the 2008Mw 7.9 Wenchuan earthquake, we study effects of systematic changes in the principal stress orientation along the fault strike on rupture dynamics and ground motion using a 3‐D finite‐element method. Based on Anderson’s theory of faulting, we set up the initial stress field with rotations in stress orientations along strike for a dynamic rupture model of ...

This paper shows that the quantitative predictions of an equilibrium asset-pricing model with financial frictions are consistent with key features of the Sudden Stop phenomenon. Foreign traders incur costs in trading assets with domestic agents, and a collateral constraint limits external debt to a fraction of the market value of domestic equity holdings. When this constraint does not bind, sta...

Sudden stratospheric warmings (SSWs) are the most prominent vertical coupling process in the middle atmosphere, which occur during winter and are caused by the interaction of planetary waves (PWs) with the zonal mean flow. Vertical coupling has also been identified during the equinox transitions, and is similarly associated with PWs. We argue that there is a characteristic aspect of the autumn ...

Many conceptual change theories posit that change occurs when the learner becomes dissatisfied with the current conception (Ohlsson, 2011; Strike & Posner, 1992). A necessary component of dissatisfaction is falsifying feedback. The present experiments investigate whether participants exposed to a novel method for eliminating the ability to directly falsify a misconception will still be able to ...
