This note calls attention to a variant formulation of the least-squares adjustment procedure [1] that should prove increasingly attractive as electronic dataprocessing equipment becomes ever more widely available. It indicates that the statistician need not concern himself with the two rituals featured in traditional textbook presentations—namely, the construction and solution of the convention...

A least-squares formulation of the Moving Discontinuous Galerkin Finite Element Method with Interface Condition Enforcement (LS-MDG-ICE) is presented. This method combines MDG-ICE, which uses a weak that separately enforces conservation law and corresponding interface condition treats discrete geometry as variable, Petrov-Galerkin (DPG) methodology Demkowicz Gopalakrishnan to systematically gen...

Tone mapping is used to compress the dynamic range of image data without distortion. To HDR images and prevent halo artifacts, a tone method proposed based on least squares method. Our first uses weights for estimation illumination, detail layer obtained by Retinex model. Then, global function with parameter range, fitting histogram equalization. Finally, illumination are fused obtain LDR image...

In terms of observational data, there are some problems in the standard Big Bang cosmological model. Inflation era, early accelerated phase of the evolution of the universe, can successfully solve these problems. The inflation epoch can be explained by scalar inflaton field. The evolution of this field is presented by a non-linear differential equation. This equation is considered in FLRW model...

least squares method (lsm) is an accurate and rapid method for solving some analytical andnumerical problems. this method can be used to estimate the average reservoir pressure in well testanalysis. in fact, it may be employed to estimate parameters such as permeability (k) and porevolume (vp). regarding this point, buildup, drawdown, late transient test data, modified muskatmethod, interferenc...
