chemical hardness (), absolute electronegativity (), and electrophilicity () have importantapplications in inorganic chemistry. these concepts are defined quantitatively as � � �� � ����,� � �� � ����, � � ������where i is the ionization energy and a is the electron affinity. in thisstudy, graphical method was used to see the relation of electron configuration with chemicalhardness, absolute...

abstract the muskingum method is frequently used to route floods in hydrology. however, application of the model is still difficult because of the parameter estimation’s. recently, some of heuristic methods have been used in order to estimate the nonlinear muskingum model. this paper presents a efficient heuristic algorithm, simulated annealing, which has been used to estimate the three paramet...

Abstract Adjacency matrix A(G)=[aij] yields the graph energy, which is equal to addition of absolute values eigenvalues G. This research investigates energy class in terms another after removing a vertex. After deleting vertex, relationship between complete E[ k n ] and splitting E(S’ [ ]) discovered.

Here, we point out on an intriguing mapping between the quantum harmonic oscillator ground state and zero absolute vorticity plane Couette flow of a Boltzmann-like density distributed ideal gas in thermal equilibrium. The is obtained when embedded rotating frame whose rotation rate equal to half frequency oscillator.
