On Deza graphs with triangular and lattice graph complements as parameters

Under consideration are the strictly Deza graphs that are obtained from the complements to triangular and lattice graphs, the Chang graphs, and the Shrikhande graph, by means of their order two automorphisms. It is shown that these graphs are characterized in the class of strictly Deza graphs by the parameters and the structure of neighborhoods.  

Entropy Generation and Thermal Radiation Effects on Nanofluid over Permeable Stretching Sheet

In the present paper, effects of entropy generation and nonlinear thermal radiation on Jeffery nanofluid over permeable stretching sheet with partial slip effect were analyzed. The suitable similarity transformation is utilized for the reduction of a set of governing equations, which are solved by using Differential Transformation Method (DTM) with the help of symbolic software MATHEMATICA. The accuracy of impact of slip parameter on coefficient of skin friction by using DTM and numerical method (Shooting technique with fourth-order Runge-Kutta) is illustrated and good agreement is found. Further, velocity, temperature, nanoparticle volume fraction and entropy generation profiles are shown graphically and studied in detail for various physical parameters. We notice that, as slip parameter rises the velocity and entropy generation profile rises. Enhancement in the effect of nonlinear thermal radiation reduces the entropy generation.
