Various methods have been presented to improve the performance of buildings against earthquakes. Friction damper device is one of the energy dissipation devices that appropriately absorbs and dissipates the input energy and decreases displacements. In this paper, the possibility of using endurance time method to determine the efficiency index and optimum slip load for these dampers was investig...

In this paper, the relationship between time and frequency domain joint channel estimation (JCE) in multi-branch, i.e., multi-user and/or multiple antenna, systems is explained. It is proved that the design criterion of optimum pilots for frequency domain JCE can be deduced from the design criterion of optimum pilots for time domain JCE, and vice versa. This uncovers that the optimum pilots in ...

oil production optimization is one of the main targets of reservoir management. smart well technology gives the ability of real time oil production optimization. although this technology has many advantages; optimum adjustment or sizing of corresponding valves is still an issue to be solved. in this research, optimum port sizing of inflow control devices (icds) which are passive control valves ...
