This paper presents a new approach to better utilize international air-corridors for formation flights. Using Particle Swarm Optimization, we show how different long-range flights can be brought together to form a formation. The idea serves both to increase international air-corridor capacities together and to decrease fuel consumption up to 8-10%. Case studies show that there are many places which such an approach could effectively be implemented to help cope with increase in fuel price as well as the demand for aerial transport of passengers and goods  

An attempt was made to produce an iron bearing and a titanium bearing product, using solid state reduction of Fanouj mine titanomagnetite concentrate. For this purpose, the concentrate was mixed with pulverised coal and sodium carbonate and was reduced in a muffle furnace. The product was then subjected to magnetic separation. In this work, the effect of temperature, time, added coal and additive amount on reduction was studied. The Separation Efficiency (SE) index was used for optimisation of the process. Using SE is more appropriate than degree of metallization, which is usually used, for optimising reduction processes. The results show that the optimal conditions are 1325°C, 2.5 h, 25...
