At the current stage of integration renewable energy sources into power systems many countries, requirements for compliance with established technical characteristics are being applied to generation. One such requirement is installed capacity utilization factor, which extremely important optimally placing facilities based on and successful development energy. Efficient placement maximizes facto...

In the field of cold bending, it is necessary to use ball mandrels, especially bend thin-walled tubes with a small radius. However, bending process mandrel complex and expensive, easy jam core inside tube. To solve these issues, we designed two kinds hollow non-ball schemes low stiffness that were suitable for radius tubes. We evaluated forming quality numerically influence section length thick...

Blind voice separation refers to retrieve a set of independent sources combined by an unknown destructive system. The proposed separation procedure is based on processing of the observed sources without having any information about the combinational model or statistics of the source signals. Also, the number of combined sources is usually predefined and it is difficult to estimate based on the ...

Feature selection is a fundamental pre-processing step in machine learning that aims to reduce the dimensionality of dataset by selecting most effective features from original features. This process regarded as combinatorial optimization problem, and grey wolf optimizer (GWO), novel meta-heuristic algorithm, has gained popularity feature due its fast convergence speed easy implementation. In th...

The hexapod wall climbing robots have the advantages of traversing complex surfaces. To traverse environments autonomously, it must possess capability to select gait parameters and paths appropriate for surface. Path planning optimization is a fundamental issue in aspect stable, energy efficient robot navigation with static dynamic obstacles. Traditional statistical models been developed get op...
