This letter proposes a limited feedback-based selfish linear precoding (SLP) strategy for downlink twouser MIMO systems. In the proposed strategy, each user selfishly chooses the other user’s precoding matrix which minimizes its capacity loss. The proposed SLP strategy has two advantages comparing with traditional linear precoding strategies. First, SLP improves the system capacity by resisting...

Incremental Dynamic Analysis (IDA) procedure is now considered as a robust tool for estimating the seismic sidesway collapse capacity of structures. However, the procedure is time-consuming and requires numerous nonlinear response-history analyses. This paper proposes a simplified Modal Pushover Analysis (MPA) procedure for IDA of RC moment-resisting frames. The proposed method uses the dynamic...

In order to study planting date impacts and ending season drought stress  on grain yield and  gaining weight  rate  and wheat filling period characteristics in new advanced bread wheat genotypes ,this research  is done by using plan statistical  of spilt plot  in form of complete random blocks basic  plot with 3 replications in both common separated irrigation  and ending season drought  stress...

The work presented in this paper investigates the strength of moment-resisiting apex brackets cold-formed steel portal frames. results two previously reported full-scale frame tests, where frames failed through buckling bracket, were used to validate a finite element model that included material nonlinearity, geometric imperfections, and bolt bearing behaviour. From test as well results, import...

The Glass Fiber-Reinforced Polyurea (GFRPU) which is the composite by elastic polyurea and milled glass fiber have mechanical characteristics to enhance tensile strength as well ductility. It must be reinforcement materials in repair retrofit applications for strengthening structural capacity has a merit of simple construction spray coating prevent debonding from concrete surfaces unlike existi...

cascading models in network optimization tasks. As a further step in the comparison between topological and flow-based models, in [Fang et al., 2015b] we have tackled the problem of searching for the most favorable pattern of link capacity allocation for a CI power network with the objective of resisting to cascading failures with limited investment costs. As before, low vulnerability and low c...
