In order to shorten concrete temperature difference between inside and outside, the internal temperature of concrete were considered. The method of laying cooling pipes in concrete was proposed. First of all, a certain thickness of concrete was cast in the pit or groove, and its surface was slotted. After that, the steel and scaffolding were installed on it. Using the method, we can reduce the internal...
In this paper we consider the problem of determining whether an unknown arithmetic circuit, for which we have oracle access, computes the identically zero polynomial. This problem is known as the black-box polynomial identity testing (PIT) problem. Our focus is on polynomials that can be written in the form f(xmacr) = Sigmai=1k hi(xmacr) ldr gi(xmacr), where each hi is a polynomial that depends on...
