On the Quasi-Isotropic Inflationary Solution
In this paper we find a solution for a quasi-isotropic inflationary Universe which allows to introduce in the problem a certain degree of inhomogeneity. We consider a model which generalizes the (flat) FRW one by introducing a first order inhomogeneous term, whose dynamics is induced by an effective cosmological constant. The 3-metric tensor is constituted by a dominant term, corresponding to a...
متن کاملQuasi-static Energy Absorption of Wood
This study presents the experimental results for a series of tests on the uniaxial quasi-static crushing of cubical specimens of 50mm side for two species of wood such as Jack wood and Indian Fig. Compression tests were conducted on universal testing machine of 400kN capacity and at a constant deformation rate of 8mm/min. The woods were separately tested in the two principal directions i.e., gr...
متن کاملIntersection Quasi-Orderings: An Alternative Proof
This note provides an alternative proof of a known result on the existence of collections of orderings generating intersection quasi-orderings. Instead of proving the result from first principles, it is illustrated how it can be obtained by making use of an analogous relationship between partial orders and linear orders. Journal of Economic Literature Classification Nos.: C60, D11, D71. ∗ I tha...
متن کاملProof techniques in quasi-Monte Carlo theory
In this survey paper we discuss some tools and methods which are of use in quasiMonte Carlo (QMC) theory. We group them in chapters on Numerical Analysis, Harmonic Analysis, Algebra and Number Theory, and Probability Theory. We do not provide a comprehensive survey of all tools, but focus on a few of them, including reproducing and covariance kernels, Littlewood-Paley theory, Riesz products, Mi...
متن کاملCalibration of quasi-isotropic parallel kinematic machines: Orthoglide
The paper proposes a novel approach for the geometrical model calibration of quasi-isotropic parallel kinematic mechanisms of the Orthoglide family. It is based on the observations of the manipulator leg parallelism during motions between the specific test postures and employs a low-cost measuring system composed of standard comparator indicators attached to the universal magnetic stands. They ...
