The geometrical modeling method of real details elements, the analytical and experimental methods are used in the research. The tasks of the work are, firstly, to classify as linear sizes the elements additionally linear coordinating sizes that determine the detail elements location and, secondly, to justify the basic deviation of the tolerance interval for the element's linear size. The aim of the paper is to develop alternatives for improving the system linear sizes tolerances and dimensional fits in the international standard ISO 286-1. The study is carried out on the urgent topic for technical products quality providing in the tolerancing process of the component parts. The linear sizes tolerances and fits system modernization This software should facilitate the proper fitting of measurements with a simple Interface. Compared to the commonly used York fit, this method has the correct prescription for measurement error propagation. This program takes the users' Input data and fits a linear regression to it using the prescription presented by Mahon (1996). We find that by using information in the non- linear power spectrum, and combining the GC and WL probes, we can constrain the dark matter-dark energy coupling constant squared, β 2, with precision smaller than 4% and all other cosmological parameters better than 1%, which is a considerable improvement of more than an order of magnitude compared to corresponding linear power spectrum forecasts with the same survey specificationsįitting program for linear regressions according to Mahon (1996) We then use these fitting functions to perform forecasts on the constraining power that future galaxy-redshift surveys like Euclid will have on the coupling parameter, using the Fisher matrix method for galaxy clustering (GC) and weak lensing (WL). These fitting formulas can be used to test the predictions of the model in the non- linear regime without the need for additional computing-intensive N-body simulations. Their validity is demonstrated for all available simulations in the redshift range 0z=–1.6 and wave modes below 0k=1 h/Mpc. We obtain fitting functions for models in which the dark matter-dark energy coupling is constant. Our interest resides in estimating forecasts for future surveys like Euclid when we take into account non- linear effects, relying on new fitting functions that reproduce the non- linear matter power spectrum obtained from N-body simulations. We consider cosmological models in which dark matter feels a fifth force mediated by the dark energy scalar field, also known as coupled dark energy.
