Analysis of Maximum Ratio Transmission in Ad Hoc Networks with Imperfect Channel State Information
Advances in Intelligent Systems Research, 2013 In this paper, the performance of maximum ratio transmission (MRT) with imperfect channel state information (CSI) is analyzed. Different from previous works, a multiuser scenario is considered. By modeling the source nodes as a homogeneous Poisson point process, the outage probability is derived in closed form.

Non-bifurcation behavior of laminated composite plates under in-plane compression [PDF]
Bulletin of the Polish Academy of Sciences: Technical SciencesThe paper deals with bifurcation and/or non-bifurcation post-buckling curves of composite plates under biaxial compression. For different lay-up sequences, a coupling, i.e. extension-bending (EB) is considered. The current investigations present distinct
