Following the famous Netflix Prize competition, accuracy metrics (such as RMSE) became a de facto standard in the community to evaluate and compare performance of recommendation algorithms. However, it has been shown, that accuracy is not the best way to quantify the quality of recommendations, especially in the context of predicting online performance from offline evaluations [1]. Thus, it mak...

The geology of the Himalayas is intricated and intriguing. It features numerous tectonic bodies structures too complex to interpret. Along with such mysteries it has many common geohazards, as landslides. In this study, a detailed geological investigation carried out overcome discrepancies in structural interpretation, nature two crystalline bodies, non-uniformity mapping central Himalayan arc,...

In recent decades, the construction of statistically similar representative volume elements (SSRVEs) materials for use in numerical analyses has been accomplished utilizing various methods, tools, and frameworks. Such a framework is introduced this work, where creation 3D SSRVEs metal matrix composites was investigated to assess their mechanical properties with reference material’s microstructu...

this work is a primary achievement in studying the co2 and n2–oil systems. to predict gas-liquid relative permeability curves, a shan-chen type multicomponent multiphase lattice boltzmann model for two-phase flow through 2d porous media is developed. periodic and bounce back boundary conditions are applied to the model with the guo scheme for the external body force (i.e., the pressure gradient...

Plotting solution sets for particular equations may be complicated by the existence of turning points. Here we describe an algorithm which not only overcomes such problematic points, but does so in the most general of settings. Applications of the algorithm are highlighted through two examples: the first provides verification, while the second demonstrates a non-trivial application. The latter ...

A suitable model for predicting the product quality of vacuum gas oil (VGO) catalytic hydrocracking is developed. Data were obtained using an experimental catalytic hydrocracking reactor loaded with the Ni-Mo/Al2O3-SiO2 catalyst. A set of experimental runs was conducted under various operating temperatures from 380 to 450 ℃. Three distribution models were used t...
