equipment based on its complexity and compared with simple crude distillation‚ which is assigned a complexity factor of 1.0. The complexity of each piece of refinery equipment is then calculated by multiplying its complexity factor (Table Below) by its throughput ratio as a percentage of crude distillation capacity. Adding up the complexity values assigned to each piece of equipment‚ including crude distillation‚ determines a refinery’s NCI number. The higher the NCI number of a refinery‚ the more complex

broad view of the use of antenna arrays in wireless communications. In particular‚ we will investigate the capacity of systems using multiple transmit and/or multiple receive antennas. This provides a fundamental limit on the data throughput in multipleinput multiple-output (MIMO) systems. We will also develop the use of transmit diversity‚ i.e.‚ the use of multiple transmit antennas to achieve reliability (just as earlier we used multiple receive antennas to achieve reliability via receive diversity)

techniques. MIMO (Multiple Input and Multiple Output) is a technique in which multiple antennas are used both at the receiver and the transmitter for better communication performance. In 1996‚ Greg Raleigh and Gerard J. Foschini refined new approaches to MIMO technology‚ considering a configuration where multiple transmit antennas are co-located at one transmitter to improve the link throughput effectively. It is been said that MIMO offers significant increase in data throughput and quality without additional
