A new method is proposed to realize the blind separation of speech signals under underdetermined conditions. Before estimating mixed parameters, single-source interval pre-extraction operation first "filters" out a part which obviously not single source. The time-frequency source analysis domain category.The simulation results show good performance algorithm.

The unidirectional rolled Mg–Zn–Gd sheet usually exhibited non-basal texture with two peaks whose tilting angle were about 42° from normal direction to transverse (TD), which would cause the mechanical anisotropy. In this study, multi-cross rolling followed by annealing was used tailor and anisotropy for alloy. With increasing temperature, basal gradually transformed into circle multi-peaks. or...

obviously navigation is one of the most complicated issues in mobile robots.intelligent algorithms are often used for error handling in robot navigation. thispaper deals with the problem of inertial measurement unit (imu) error handling byusing extended kalman filter (ekf) as an expert algorithms. our focus is put onthe field of mobile robot navigation in the 2d environments. the main challenge...

The recognition and the calculation of all branches of solutions of the nonlinear boundary value problems is difficult obviously. The complexity of this issue goes back to the being nonlinearity of the problem. Regarding this matter, this paper considers steady state reactive transport model which does not have exact closed-form solution and discovers existence of dual or triple solutions in so...

The range conditions explain its health as a management tool. Obviously, theimplementation of this important assessment requires the most appropriate study methodfor each region. In order to select the most appropriate methods of range conditions inKabirkooh grasslands of Zagros in Iran, five estimation methods (i.e. six-factor, fourfactor,vegetation and soil combination, value of pasture and c...

Herbal medicines include a range of pharmacologically active compounds: in some cases it is not well understood which ingredients are important for a therapeutic effect. The supporters of herbal medicine believe that isolated ingredients in the majority of cases have weaker clinical effects than whole plant extract, a claim that would obviously require proof in each case. Generalizations about ...

Conglomerate reservoir is an important part of unconventional oil and gas resources, which has great developmental potential. However, its sedimentary environment structural background are complex, cementation types, gravel volume fraction shape quite different, leads to strong heterogeneity. When developing a conglomerate reservoir, it extremely difficult drill because It obtain the mechanical...

this paper considers the automatic design of fuzzy rule-basedclassification systems based on labeled data. the classification performance andinterpretability are of major importance in these systems. in this paper, weutilize the distribution of training patterns in decision subspace of each fuzzyrule to improve its initially assigned certainty grade (i.e. rule weight). ourapproach uses a punish...
