Due to the outbreak of Covid-19 pandemic, college tours are no longer available, so many students have lost opportunity see their dream school’s campus. To solve this problem, we developed a product called “Virtourgo,” university virtual tour website that uses Google Street View images gathered from web scraper allowing what campuses like even when unavailable during pandemic. The project consi...

As a floating system connecting hydraulic support and scraper conveyor, the path planning of pushing mechanism is great significance for their coordinated movement. In this paper, method based on extreme learning machine (ELM) Descartes proposed. According to motion characteristics moving mechanism, it transformed into industrial robot model, coordinates key points ear seat conveyor when advanc...

effect of water gas shift reaction (co+h2o=co2+h2) on wustite reduction has been investigated by a transient, non-isothermal mathematical model based on grain model. in this model, wustite porous pellet is reduced using syngas, namely a mixture of hydrogen, carbon monoxide, carbon dioxide and water vapor. for this purpose, governing equations containing continuity equation of species and energy...

We present an efficient method for the reduction of model equations in the linearized diffuse optical tomography (DOT) problem. We first implement the maximum a posteriori (MAP) estimator and Tikhonov regularization, which are based on applying preconditioners to linear perturbation equations. For model reduction, the precondition is split into two parts: the principal components are consid...
