This paper presents some practical and guaranteed ways of studying the discrete-time/ continuous-time stability quality of large sparse matrices. The methods use projection techniques for computing an invariant subspace associated with a few outermost eigenvalues (those with largest real parts for the continuous-time case and with largest magnitudes in the discrete-time case). Standard Lyapunov...

Introduction: Studies concerning the biology and ecology of scorpions in Iran are very limited , and these studies must be begun with identification of habitats and funa of scorpions of each region in the country and completed with biological and ecological charactristics .The aim of this study was to identify and determine the funa of Lorestan scorpions. Materials and Methods: In this descrip...
