Regional Integration in South Asia: An Analysis of Trade Flows Using the Gravity Model [PDF]

open access: yes
The study deals with trade benefits from the free trade agreement of the SAARC countries. It assesses the trade potential and trade creation with member and non-member countries. The gravity model has been used to measure the bilateral trade flows and to

Why gravity is not an entropic force [PDF]

open access: yes, 2010
The remarkable connections between gravity and thermodynamics seem to imply that gravity is not fundamental but emergent, and in particular, as Verlinde suggested, gravity is probably an entropic force.

A Method for Evaluating Dynamical Friction in Linear Ball Bearings

open access: yesSensors, 2010
A method is proposed for evaluating the dynamical friction of linear bearings, whose motion is not perfectly linear due to some play in its internal mechanism.

Crustal structure of the spreading plate boundary in Iceland and the north Atlantic from gravity data [PDF]

open access: yes, 1994
Gravity datasets from two geothermal areas in Iceland, an Iceland-wide gravity dataset, and marine gravity data from the Reykjanes Ridge at 58˚N, which can be seen as the submarine extension of the Icelandic accretionary system, have been studied in this

Preliminary design of multiple gravity-assist trajectories [PDF]

open access: yes, 2006
In this paper the preliminary design of multiple gravity-assist trajectories is formulated as a global optimization problem. An analysis of the structure of the solution space reveals a strong multimodality, which is strictly dependent on the complexity ...

The Centre of Gravity of a Circular Arc [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 1897
To find the Centre of Gravity of a Ciroular Arc. Let a (Fig. 12) be the radius, 2a the angle at the centre, AB the arc, of total mass m, G its centre of gravity symmetrically situated. Imagine the arc to be part of a circle of string rotating uniformly with velocity u round C and of linear density ...

Centre of gravity of rigid lenses: Some design considerations

open access: yes, 1987
Rigid lens centration and stability are the net result of numerous forces acting on the lens. One of these forces is gravity. The way in which gravitational effects can alter with various lens parameter changes is illustrated using typical lens designs ...

Centre of Gravity of Annual Statistics [PDF]

open access: yesNature, 1910
THE principle of taking the centre, of gravity of annual rainfall is free from objection, but Mr. Cook's method (NATURE, March 31) is mathematically incorrect. Annual statistics should not be plotted on a straight line, but round a circular ring in accordance with the probable etymology of the term (annus, anulus).

Modelling The Trade Flows of The Gulf Cooperation Council Countries: A New Approach to Gravity Model [PDF]

open access: yes
This study analyzes the trade flows of the Gulf Cooperation Council (GCC) both among its member countries and with the rest of the world by employing a panel data gravity model in the context of the single country approach in order to capture the impacts
