This journal's issue includes articles that describe the latest research results in alloy metallurgy, building materials and construction technologies including building seismic provision and results of analytical modelling of mechanical properties of shrink-fitted thick-walled cylinders and nose landing gear for Boeing 777. There is also analysed a hybrid system solar chimney-air soil heat exchanger for natural ventilation and modified particle swarm optimisation for maximum power point tracking for solar photovoltaic systems and presented mathematical modelling of agricultural insurance pricing in Morocco. This volume will be helpful to many engineers in machinery, manufacturing, energy industry and construction.
