Personification of interface agents has been speculated to have several advantages, such as a positive effect on agent credibility and on the perception of learning experience. However, important questions less often addressed so far are what effect personification has on more objective measures, such as comprehension and recall, and furthermore, under what circumstances this effect (if any) oc...

There is a profound connection between gravity and Earth's motion. It the force of that ensures smooth operation our planet in its designated orbit, enables it to receive radiant heat generated by Sun, gives rise four seasons throughout journey. This paper provides concise elucidation concept focuses on interrelation motion, presenting substantial data evidence refute traditional notion tilt so...

Identity is seen as a cultural and social construct, which indicates how we have been embodied and how we might represent ourselves. The knowledge that identities are the outputs of discourses is a familiar characteristic of some societal concepts. Gender, as an identity or a sense of our identity we build for ourselves, rather than something we are born with, is a constructed cultural category...

The dynamics of wavepackets in a relativistic Dirac oscillator (DO) is considered. A comparison to nonrelativistic spin-orbit pendulum effect is discussed. Particular relativistic effects, like Zitterbewegung in spin motion, are found in Dirac representation. This trembling motion disappears in Foldy-Wouthuysen representation. A substantial difference between the dynamics of wavepackets corresp...

Despite technical advances, respiratory motion remains a major impediment in a substantial amount of patients undergoing coronary magnetic resonance angiography (CMRA). Traditionally, respiratory motion compensation has been performed with a one-dimensional respiratory navigator positioned on the right hemi-diaphragm, using a motion model to estimate and correct for the bulk respiratory motion ...

Dynamic models and power models of autonomous ground vehicles are needed to enable realistic motion planning Howard & Kelly (2007); Yu et al. (2010) in unstructured, outdoor environments that have substantial changes in elevation, consist of a variety of terrain surfaces, and/or require frequent accelerations and decelerations. At least 4 different motion planning tasks can be accomplished usin...

the present paper is concerned with the generalization of the holditch theorem under oneparameterhomothetic motion on lorentzian planes. in this paper, for the homothetic lorentzian motion, weexpressed the steiner formula. furthermore, we present the holditch-type theorems.

background: 3dcrt (three-dimensional conformal radiotherapy) and imrt (intensity-modulated radiotherapy) has provided us with tools to delineate the radiation dose distribution of tumor targets. however, the precision of radiation can be compromised by respiratory motion, which usually limits the geometric and dosimetric accuracy of radiotherapy. the purpose of this study is to evaluate the imp...

purpose: this study aimed to assess the effect of boston brace on trunk muscles length as well as lower limbs and trunk range of motion in patients with idiopathic scoliosis. methods: five patients with idiopathic scoliosis with c shape curve and mean (sd) age, height, and weight of respectively 12.61(1.16) years, 1.53(0.08) m, and 35.6(6.1) kg participated in this study. spatiotemporal paramet...
