## Abstract Aromatic amino groups are replaced with deuterium via a diazonium salt intermediate. Dimethylformamideβd~7~ is the deuterium donor in this mild replacement method that yields aromaticβ__d__~1~ products in high isotopic purity. The presence of methyl groups lowers the isotopic purity of

## Abstract In the process of discreteβsizing optimal design of truss structures by Genetic Algorithm (GA), analysis should be performed several times. In this article, the force method is employed for the analysis. The advantage of using this method lies in the fact that the matrices corresponding
Fuzzy models describe nonlinear input-output relationships with linguistic fuzzy rules. A hierarchical fuzzy modeling is promising for identification of fuzzy models of target systems that have many input variables. In the identification, (1) determination of a hierarchical structure of submodels, (
In this paper, a solution method is presented to solve the eigenproblem arising in the dynamic analysis of non-proportional damping systems with symmetric matrices. The method is based on the Lanczos method to generate one pair of Krylov subspaces consisting of trial vectors, which is then used to r
