چکیده

In this paper, a new equidistant filling theory based on the level set function and corresponding numerical algorithm dynamic finite difference method were proposed. Firstly, closed curve is defined as zero-value contour of function. Then, equation, partial differential was built to get function, proposed solve Secondly, three types cross sections, simple polygon, multi-island multi-hole used test effect algorithm. The results show that in paper solved problem these sections well. addition, any complex section can be filled by calculation cost significantly related number offsets, but not directly complexity. Finally, remanufacturing typical crankshaft hot forging die proves effectively produce repair path die. surface remanufactured smooth, there no efects such porosity slag inclusion after machining. Compared with making die, manufacturing saved more than 50%, efficiency improved 60%. This because machining allowance additive very small, it quickly repaired site.

A path following interior-point algorithm for semidefinite optimization problem based on new kernel function

In this paper, we deal to obtain some new complexity results for solving semidefinite optimization (SDO) problem by interior-point methods (IPMs). We define a new proximity function for the SDO by a new kernel function. Furthermore we formulate an algorithm for a primal dual interior-point method (IPM) for the SDO by using the proximity function and give its complexity analysis, and then we sho...

A New Method for Root Detection in Minirhizotron Images: Hypothesis Testing Based on Entropy-Based Geometric Level Set Decision

In this paper a new method is introduced for root detection in minirhizotron images for root investigation. In this method firstly a hypothesis testing framework is defined to separate roots from background and noise. Then the correct roots are extracted by using an entropy-based geometric level set decision function. Performance of the proposed method is evaluated on real captured images in tw...
