mathematical modeling and simulation of microbial polyhydroxybutyrate (phb) production process is beneficial for optimization, design, and control purposes. in this study a batch model developed by mulchandani et al., [1] was used to simulate the process in matlab environment. it was revealed that the kinetic model parameters were estimated off the optimal or at a local optimal point. therefore...

in this study, the effective factors on warpage in short fibre reinforced thermoplastic composites has been studied. first of all, the effective factors in manufacturing process were detected and then in order to decrease the number of experiments, the approach of design of experiments has been applied. by using micromechanics theory in composites and coefficients of thermal expansion models, a...

Optimization of process parameter is one of the ideal goals in laser sintering. The results of this process were measured as output parameters like: density, micro hardening, macro hardening, tension, roughness, stiffness, balling. In this paper, the influence of input parameter such as laser power, scan speed, material powder and etc are surveyed on output parameter like balling affection and ...
