This research aims provide insights into effective utilization all three these components in order achieve a competitive advantage. aimed assess 210 (SMEs) by evaluating their sales volume. participants for t...

in today's dynamic and uncertain environment, knowledge is a strategic source for organizations to gain the competitive advantage and innovation. in this research, we have investigated mediating role of knowledge management between environmental uncertainty and organizational innovation. data was collected through questionnaire from 89 large and medium sized manufacturing companies in suburb ma...

the objective of this study was to determine the optimum replacement strategy using dynamic programming for dairy herds in fars province. a dairy cow is kept several lactations for milk production in the herd. after spending several lactations, milk production gradually begins to decline, while animal health problems rises simultaneously. so one of the most important management decisions of dai...

In this study, the dynamic buckling of the embedded laminated nanocomposite plates is investigated. The plates are reinforced with the single-walled carbon nanotubes (SWCNTs), and the Mori-Tanaka model is applied to obtain the equivalent material properties of them. Based on the sinusoidal shear deformation theory (SSDT), the motion equations are derived using the energy method and Hamilton's p...
