Even if Einstein’s General Relativity achieved a great success and overcame lots of experimental tests, it also showed some shortcomings and flaws which today advise theorists to ask if it is the definitive theory of gravity. In this letter Proceeding we show that, by assuming that advanced projects on the detection of Gravitational Waves (GWs) will improve their sensitivity, allowing to perfor...
in this thesis, a structured hierarchical methodology based on petri nets is used to introduce a task model for a soccer goalkeeper robot. in real or robot soccer, goalkeeper is an important element which has a key role and challenging features in the game. goalkeeper aims at defending goal from scoring goals by opponent team, actually to prevent the goal from the opponent player’s attacks. thi...
evaluation of functional disability using proper instruments, like health assessment questionnaire (haq) in patients with rheumatoid arthritis (ra), is necessary not only for quality of life assessment, but also as a useful marker for disease activity. haq has been translated into many languages. to validate the persian version of stanford haq. persian version of the haq (pe-haq) with culturall...
1.1 introduction “i see translation as the attempt to produce a text so transparent that it does not seem to be translated. a good translation is like a pane of glass. you only notice that it’s there when there are little imperfections- scratches, bubbles. ideally, there shouldn’t be any. it should never call attention to itself.” “norman shapiro” (venuti, 1995:1) edward fitzgerald is the br...
Let be a differentiable action of a Lie group on a differentiable manifold and consider the orbit space with the quotient topology. Dimension of is called the cohomogeneity of the action of on . If is a differentiable manifold of cohomogeneity one under the action of a compact and connected Lie group, then the orbit space is homeomorphic to one of the spaces , , or . In this paper we suppo...
Abstract Parallel mechanisms have the advantage of high rigidity, large payload capability, and so on, but positioning accuracy is affected by elastic deflection arising from external load gravity. An approach to improving compensating presented with a 3- R RS parallel mechanism as research object. The implemented introducing springs on moving platform limbs. Taking load, spring force, gravity,...
in the present work properties of rossby and inertia gravity waves are investigated based on proper orthogonal decomposition (pod) functions. the pod functions are constructed using analytical, experimental or numerical data recorded as snapshots. the pod basis can be carried out to make a reduced order model by galerkin projection of governing equations onto these functions. in this paper, the...
This paper describes a prototype virtualized file system, Prism, for supporting hosted servers and utility computing. Prism provides a filesystem service that allows lightweight creation of filesystems for new users from existing filesystems. All users’ filesystems are mutable and yet isolated from each other. In our experiments, new filesystems can be created from existing ones in under one-fi...
simultaneous capillary dominated displacement of the wetting and non-wetting phases are processes of interest in many disciplines including modeling of the penetration of polluting liquids in hydrology or the secondary migration in petroleum reservoir engineering. percolation models and in particular invasion percolation is well suited to characterize the slow immiscible displacement of two flu...
