an h-magic labeling in a h-decomposable graph g is a bijection f : v (g) ∪ e(g) → {1, 2, ..., p + q} such that for every copy h in the decomposition, σνεv(h) f(v) +  σeεe(h) f(e) is constant. f is said to be h-e-super magic if f(e(g)) = {1, 2, · · · , q}. a family of subgraphs h1,h2, · · · ,hh of g is a mixed cycle-decomposition of g if every subgraph hi is isomorphic to some cycle ck, for k ≥ ...

this study examins effects of trade liberalization on the wage inequality across industries and between genders within these industries by utilizing the data of micro-level households’ income and expenditures surveys and trade statistics over 2001-2011. the analysis is carried based on the heckscher–ohlin’s theory in international trade and baker’s taste discrimination theory at firms. we use q...

In this study, delay-dependent robust stability problem is investigated for uncertain neutral systems with discrete and distributed delays. By constructing an augmented Lyapunov-Krasovskii functional involving triple integral terms and taking into account the relationships between the different delays, new less conservative stability and robust stability criteria are established first using the...

polyester polyol can be used in high energy propellant as a binder.In this research, polyazido polyester was synthesized from direct polycondensation reaction between adipic acid and 2,2-bis(bromomethyl)-1,3-propanediol. Then, azidation of poly bromoester afford polyazidoester as an energetic polyester. polyazidoester have identified and characterized by FTIR,HNMR,GPC,DSC and elemental analysis...

the effect of fiber surface modification on physical and mechanical properties of kraft pulp wasstudied with and without chitosan. first, the amount of carboxyl groups of kraft pulp at differentaddition levels (0, 2, 3, 4 and 6%) of hydrogen peroxide was determined by means of methylene bluetest. then, the samples containing the highest carboxyl groups were treated at ph=8.5 with chitosan at0.7...

Cylotrimethylenetrinitramine (RDX), with the chemical formula C3H6N6O6,is an energetic organic molecule used widely in military and industrial commodities ofexplosives. By stimulating RDX through exerting temperature or mechanical conditionssuch as impact or friction, decomposition reaction occurs at a very high rate. Moleculardynamics techniques and LAMMPS code with Rea...

The aim of this study is decomposition of the changes in energy consumption with emphasizing the structural changes in Iran during 2001-2011 using Input- Output Structural Decomposition Analysis (I_O SDA). Structural changes in this study represent the changes in structure of intermediate input in sectors and also changes in structure of final demand categories. Structural changes in intermedia...
