THE equation of the plot of thermogravimetric data is useful in kinetic analysis (1–12), but since it contains an exponential integral, many workers prefer approximate expressions. The best balance of ...

The questions in this quiz are suitable for GCSE maths students studying approximation, rounding to decimal places, rounding to significant figures, truncation, estimating calculations, limits of ...

Make sure you are confident in calculating with negative numbers, which is a skill often needed to solve equations. To solve the equation, do the inverse operation. The inverse of multiplying by 12 is ...

Abstract: Reachable sets for a dynamical system describe collections of system states that can be reached in finite time, subject to system dynamics. They can be used to guarantee goal satisfaction in ...

Abstract: A power electronic transformer (PET) can flexibly regulate the power flow of a network and facilitate the integration of distributed energy resources via AC/DC networks. With the continuous ...
