The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a ...

Abstract: Microelectromechanical system (MEMS) wind sensors manufactured from polysilicon semiconductors require precise operating conditions, primarily temperature control, to ensure accurate ...

Cooler temperatures rule today, feeling like fall! The more robust showers and storms have shifted east with the cold front. Clouds are still prevalent farther south, whereas a clearer sky resides ...

Abstract: The main purpose of this paper is to develop an adaptive PID controller of a quadrotor. We first developed a linear PID controller based on Ziegler and Nichols method, then we developed a ...
