Kakaee, Keshavarz,

In this study it has been tried, to compare results and convergence rate of sensitivity analysis and conjugate gradient algorithms to reduce fuel consumption and increasing engine performance by optimizing the timing of opening and closing valves in XU7/L3 engine. In this study, considering the strength and accuracy of simulation GT-POWER software in researches on the internal combustion engine...

With respect to importance of the conjugate gradient methods for large-scale optimization, in this study a descent three-term conjugate gradient method is proposed based on an extended modified secant condition. In the proposed method, objective function values are used in addition to the gradient information. Also, it is established that the method is globally convergent without convexity assu...

In this paper, an efficient conjugate gradient method for unconstrained optimization is introduced. Parameters of the method are obtained by solving an optimization problem, and using a variant of the modified secant condition. The new conjugate gradient parameter benefits from function information as well as gradient information in each iteration. The proposed method has global convergence und...

ELISA data is usually handled in the MS Excel worksheets through different methods and different formulas. Accurate and precise calculations of the data is time consuming and tedious. ELISA Analyzer was developed with a user friendly interface to streamline titration and analysis of the data obtained from ELISA and improve rapid and lucid presentation of the results. The software can also hel...

carpal fracture-dislocation is regarded as an unusual orthopedic injury and, thus, orthopedic surgeons are less experienced in dealing with and treating these fractures and dislocations. we report a 20-year-old worker man suffering from an unusual carpal fracture-dislocation. there was trans-scaphoid fracture and lunate dislocation with other carpal proximal bones toward volar of the wrist. two...
