A sparsity-preserving spectral preconditioner for power flow analysis
Authors:
Publisher and Date:(TUBITAK Scientific & Technical Research Council Turkey, 2016)Due to the ever-increasing demand for more detailed and accurate power system simulations the dimensions of mathematical models increase. Although the traditional direct linear equation solvers based on LU factorization are robust they have limited scalability on the parallel platforms. On the other hand simulations of the power system events need to be performed at a reasonable time to assess the results of the unwanted events and to take the necessary remedial actions. Hence to obtain faster ...

ARE THE ARBITRATORS SUITABLE TO APPLY PUBLIC POLICY PROVISIONS IN INTERNATIONAL COMMERCIAL ARBITRATION?
Authors:
Publisher and Date:(Seçkin Yayıncılık, 2017)States virtually maintain some restrictions upon the subject matter of arbitration such as states’ public policy provisions. The extent of public policy in the international commercial arbitration becomes more comprehensive than that of the New York Convention, where it might be a defence against enforcement when the arbitral award is rendered; hence the problem occurs only at the final stage of arbitral process. Besides that, arbitrability also directly relates to public policy provisions ...
