This book includes nine chapters detailing recent advances in engineering research. Chapter One considers the factors affecting fuel consumption in the open pit mining model by investigating the existing equipment and machinery, and examines the results and consequences of reducing the effects of fuel mismanagement and increasing energy efficiency. Chapter Two aims to address the coaxial mixer principle and comprehensively discuss its agitation mechanism applied to the single and multiphase flows considering Newtonian and non-Newtonian fluids. Chapter Three presents a methodological framework for the implementation of Geographic Information Systems (GIS) for the management of cultural heritage. Chapter Four considers 182 licensed wind farms that are under operation in various parts of Turkey using the Data Envelopment Analysis. Chapter Five discusses the influence of cooling rate on microstructure evolution and mechanical properties for a thermomechanically processed near eutectoid steel, particularly with Nb microalloying. Chapter Six concerns a non-standard multicopter design. Chapter Seven reports on pulse generation via mode-locking and Q-switching. Chapter Eight proposes an energy-efficient write scheme for phase change memory. Finally, Chapter Nine reveals the orbiting satellite dynamics in the form of nonlinear stochastic differential equation (SDE) and state vectors.
