Grand theft algorithm: purposeful play, appropriated play and aberrant players
(ACM Press, 2008)This paper explores ideas about 'appropriated play' within computer games. It identifies different forms of 'purposeful' and 'aberrant' playing and proposes a model of players' motivations. This will enable a discussion ... -
Grand-design spirals in the core of NGC 5248
(2001)We report the detection of a bisymmetric nuclear spiral structure in the spiral galaxy NGC 5248.The two red spiral arms can be followed for about 3 arcsec, before they appear to end inside the radius of the circumnuclear ... -
GRAPE-SPH chemodynamical simulation of elliptical galaxies - I : Evolution of metallicity gradients
(2004-01-21)We simulate the formation and chemodynamical evolution of 124 elliptical galaxies using a GRAPE-SPH code that includes various physical processes that are associated with the formation of stellar systems: radiative cooling, ... -
GRAPE-SPH chemodynamical simulation of elliptical galaxies - II : Scaling relations and the fundamental plane
(2005-08-21)We simulate the formation and chemodynamical evolution of 128 elliptical galaxies using a GRAPE-SPH code that includes various physical processes that are associated with the fort-nation of stellar systems: radiative ... -
Graph-Based Patent Mining for Mechanical Designs
(Institute of Electrical and Electronics Engineers (IEEE), 2024-06-25)Patents represent a rich source of design innovations, prompting the application of different technologies. Machine learning, text and data mining, similarity scoring, and evolving ontology methods are among the various ... -
A graph-based spectral classification of Type II supernovae
(2023-06-06)Given the ever-increasing number of time-domain astronomical surveys, employing robust, interpretative, and automated data-driven classification schemes is pivotal. Based on graph theory, we present new data-driven ... -
Graphetics: When mark-making becomes writing
(2018-04-01)Graphetics is the study of how one recognizes text, and how one differentiates it from other marks and drawings, for example when one views a manuscript and has to decide ‘is this writing or just scribble?’. This article ... -
Graphical and text based challenge questions for secure and usable authentication in online examinations
(Institute of Electrical and Electronics Engineers (IEEE), 2014-12)In traditional online examination environments, physical interaction is often replaced with authentication mechanisms. The absence of face-to-face interaction increases the number of authentication challenges. The authors ... -
Graphical problems in Wittgenstein's Nachlaß
(Die Osterreichische Ludwig Wittgenstein Gesellschaft, 1995)This paper describes some features of Wittgenstein's Nachlaß which lie on the boundary between text and graphics. These deliberately ambiguous features are introduced as part of Wittgenstein's method of using "text-experiments" ... -
A graphical representation for communicating sequential processes
(University of Hertfordshire, 1997)The use of formal notations has many advantages in the specification of interactive systems. However, validating specifications written using formal notations is generally difficult as these specifications are often hard ... -
Grasps recognition and evaluation of stroke patients for supporting rehabilitation therapy
(2014-09-02)Stroke survivors often suffer impairments on their wrist and hand. Robot-mediated rehabilitation techniques have been proposed as a way to enhance conventional therapy, based on intensive repeated movements. Amongst the ... -
Grass(mannian) trees and forests: Variations of the exponential formula, with applications to the momentum amplituhedron
(2023-03-15)The Exponential Formula allows one to enumerate any class of combinatorial objects built by choosing a set of connected components and placing a structure on each connected component which depends only on its size. There ... -
Grassland futures in Great Britain – Productivity assessment and scenarios for land use change opportunities
(2018-09-01)To optimise trade-offs provided by future changes in grassland use intensity, spatially and temporally explicit estimates of respective grassland productivities are required at the systems level. Here, we benchmark the ... -
The Grassmannian for celestial superamplitudes
(2021-11-25)Recently, scattering amplitudes in four-dimensional Minkowski spacetime have been interpreted as conformal correlation functions on the two-dimensional celestial sphere, the so-called celestial amplitudes. In this note we ... -

The Gravitational Torque of Bars
(Astronomical Society of the Pacific, 2002)We have determined the gravitational torque of a sample of 45 galaxies observed at K band with the 4.2m William Herschel Telescope. The results of this sample, combined with those for a sample of 30 galaxies previously ... -
Gravitationally induced inflow in Starbursts and Agn
(2005)There is considerable evidence that the circumnuclear regions of galaxies are intimately related to their host galaxies, most directly through their bars. There is also convincing evidence for relations between the properties ... -
Gravity dependence at the bottom of the main sequence
(1999)We investigate the effects of gravity on the infrared spectra of objects around the M dwarf to brown dwarf transition. We focus on observations of the very low-mass objects TVLM513–46546 and GJ 569B from 1 to 2.5 m. These ...
