Basic relation between numerical range and Davis-Wielandt shell of an operator $A$ acting on a Hilbert space with orthonormal basis $xi={e_{i}|i in I}$ and its conjugate $bar{A}$ which is introduced in this paper are obtained. The results are used to study the relation between point spectrum, approximate spectrum and residual spectrum of $A$ and $bar{A}$. A necessary and sufficient condition fo...

We present an example of Kakutani equivalent and strong orbit equivalent substitution systems that are not conjugate. Introduction. The motivation for this example came from [2], in which Dartnell, Durand, and Maass show that a minimal Cantor system and a Sturmian subshift are conjugate if and only if they are Kakutani equivalent and orbit equivalent (or equivalently strong orbit equivalent for...

elisa data is usually handled in the ms excel worksheets through different methods and different formulas. accurate and precise calculations of the data is time consuming and tedious. elisa analyzer was developed with a user friendly interface to streamline titration and analysis of the data obtained from elisa and improve rapid and lucid presentation of the results. the software can also help ...

In this paper, we present a new approach for solving absolute value equation (AVE) whichuse Levenberg-Marquardt method with conjugate subgradient structure. In conjugate subgradientmethods the new direction obtain by combining steepest descent direction and the previous di-rection which may not lead to good numerical results. Therefore, we replace the steepest descentdir...
