Stream : School of EE & T Lecture Notes Chapter 5 : Digital Circuits

This chapter can be read at any time after Chapter 1 (“Induction: Instruments, Components and Circuits”). At the end of that document, we introduced elementary digital logic and showed how it could be constructed from simple combinations of transistors. Many of you will, by now, have constructed and tested these logic circuits in the laboratory. Where your project calls for digital logic, you a...

Addendum to Lecture Notes in Mathematical and Systems Biology

Recent developments in configuration design and optimization of mineral separation circuits; A Review

The present research reviews two basic approaches for the separation circuit configuration analysis. The first approach is to optimize the circuit configuration. In this method, after a circuit modeling, a variety of search algorithms and mathematical optimization methods are used. Previous works show that this approach has more application in the flotation process. The second approach called t...

Stage specialization for design and analysis of flotation circuits

This paper presents a new approach for flotation circuit design. Initially, it was proven numerically and analytically that in order to achieve the highest recovery in different circuit configurations, the best equipment must be placed at the beginning stage of the flotation circuits. The size of the entering particles and the types of streams including pulp and froth were considered as the bas...

Design and Construction of a Sensorless Circuit for Brushless DC Motor using Third Harmonic back Electromotive Force

In this paper the method of sensorless startup of direct current brushless motor using third harmonic back Electromotive Force (EMF) and motor startup using microcontroller for pulse width modulation, power switch control and motor output analysis is presented which renders RPM control and high speed achievement for motor. The microcontroller is used for processor and MOSFETs are used for power...
