Various books and articles have highlighted problems inherent in a least squares analysis of disproportionate cell data. The method of unweighted means, an approximate but much simpler technique, was ...

Abstract. The periodic matrix equations are strongly related to analysis of periodic control systems for various engineering and mechanical problems. In this work, a matrix form of the conjugate ...

IT is rather difficult to describe this little book. It is in no sense a systematic discussion of the construction of magic squares. Rather it consists of a series of examples to show how, by the ...
