Electrical steels are important alloys widely used in electrical instruments. The magnetic properties and low core loss of grain oriented silicon steels are closely related to the sharpness of Goss texture ({110} ).The direction of is the softest direction for magnetism.  In this work, the microstructure and dependence of orientation density along the major texture fibers on the applied cold ro...

Waste detection is one of the main problems preventing realization automated waste classification, which a basic function for robotic arms. In addition to object identification in general image analysis, waste-sorting arm not only needs identify target but also accurately judge its placement angle so that it can determine an appropriate grasping. order solve problem low-accuracy caused by irreg...

In this paper, we report our experiments in the TREC 2009 Million Query Track. Our first line of study is on proximitybased feedback, in which we propose a positional relevance model (PRM) to exploit term proximity evidence so as to assign more weights to expansion words that are closer to query words in feedback documents. The second line of study is to improve the weighting of feedback docume...

2-amino-n-benzthioazolyl benzamide (abtb) was synthesized, characterized and used for thefabrication of a potentiometric sensor for cu2+ metal ions. the electrode exhibits linear response to cu(ii) over a wide concentration range (4.79×10 -8 – 1.85×10 -1 m) with nernstian slope of 30 ± 1.5 mvper decade. the electrode can be used in the ph range from 2 to 9. it has a fast response time of about1...
