The characteristics of shale gas reservoirs and the engineering characteristics of "factory" operation lead to repeated production performance among wells, which is the theoretical basis of a probability Madeleine Pans/Molds method to calculate estimated ultimate recovery (EUR).Compared to the conventional deterministic method, the probability meth
In economic researches, much effort was devoted to the problem of how to increase the economics of countries.However, the development of a country may fluctuate a lot due to international and domestic problems.Thus, we should also evaluate the robustness of countries against unexpected economic recessions.In this paper, we use perturbation to throw
Introduction.Radar images of aircraft propellers can significantly improve the quality of their recognition and protection against simulating interference.Such images can be obtained using algorithms based on an inverse antenna aperture synthesis.A key factor determining the quality of image acquisition is the accuracy of the rotor blade rotation f
OBJECTIVE: This research aimed at comparing the qualitative chemical compositions and the surface morphology of fracture regions of eight types of Nickel (Ni) Titanium (Ti) conventional wires, superelastic and heat-activated (GAC, TP, Ormco, Masel, Morelli and Unitek), to Soda the wires with addition of copper (CuNiTi 27oC and 35oC, Ormco) after tr
The STAFF-DWP wave instrument on board the equatorial spacecraft (TC1) of the Double Star Project consists of a combination of 2 instruments which are a heritage of the Cluster mission: the Spatio-Temporal Analysis of Field Fluctuations (STAFF) experiment and the Digital Wave-Processing experiment (DWP).On DSP-TC1 STAFF consists of a three-axi
