Gypsum Plaster is an important building materials, and because of the availabilty of its raw materials.In this research the effect of various additives on the properties of plaster was studied , like Polyvinyl Acetate, Furfural, Fumed Silica at different rate of addition and two types of fibers, Carbon Fiber and Polypropylene Fiber to the plaster a
The supercritical CO2 Brayton cycle system is an important development direction of underwater platform power technology.However, due to the low temperature in the deep sea which is far away from the critical temperature of CO2, the cycle system has temperature adaptability problems.This paper proposed the plan to use CO2-based mixed working fluid
BackgroundThroughout the pandemic, governments worldwide have issued guidelines to manage the spread and impact of COVID-19 in schools, including measures around social distancing and contact tracing.Whether schools required support to implement these guidelines has not yet been explored in depth.Despite the development of a range of technologies t
This paper introduces a new color image superresolution algorithm in an adaptive, robust M-estimation framework.Using a robust error norm in the objective function, and adapting the estimation process to each of the low-resolution frames, the proposed method effectively suppresses the dragon ball lg disney outliers due to violations of the assumed
