Male, born in 1959. Professor and doctoral supervisor. He gained his Ph.D from University of Science and Technology Beijing in 1991. His research interests mainly focus on metal solidification, new continous casting technology, cast alloys and materials, etc. By now, his more than 220 academic papers have been published in journals demestic and abroad. He also holds 22 invention patents of Chin...

This paper reports on the results of an investigation to minimize and control the distribution of porosity in edge-gated copper rotor die castings. A Flow 3-D computer modeling exercise was used to simulate shot profiles that result in formation of large pores in the end rings, as well as to predict improved profiles that will reduce or eliminate the residual porosity. These model results were ...

In political science and economics, voting is traditionally conceived as a quasi-rational decision made by self-interested individuals. In these models citizens are seen as weighing the anticipated trouble they must go through in order to cast their votes, against the likelihood that their vote will improve the outcome of an election times the magnitude of that improvement. Of course, these mod...

Partially phosphorylated polyvinyl alcohol (PPVA) with aluminum phosphate (ALPO4) composites was synthesized by solution casting technique to produce (PPVA)(100-y) - (ALPO4)(y) (y = 0, 1, and 2). The surface structure and thermal properties of the films were characterized using Fourier transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA). The results showed that the films...

Casting had symbolic significance and was strictly controlled in the Shang dynasty of ancient China. Vessel casting was mainly distributed around the Shang capital, Yin Ruins, which indicates a rigorous centralization of authority. Thus, for a casting mold to be excavated far from the capital region is rare. In addition to some bronze vessel molds excavated at the Buyao Village site, another ke...

Instrumental licking of .4% saccharin solution was increased by the contingent opportunity to lick a less-preferred saccharin solution when the contingency schedule deprived the subject of the contingent response, but not otherwise. Schedules that imposed comparable amounts of response deprivation produced comparable increases in instrumental responding. The results support the hypothesis that ...

In the renewal of old process computer system of the continuous casting plant, Nippon Steel Corporation has attained cost reduction by the introduction of general-purpose PC server and OS, and middleware (NS SEMI SYSTEM) originally developed in the activity of open system solution. Also the adopting general purpose RDB to the continuous casting plant has been realized in the first time. The red...

In this communications we present an algorithm to solve an inverse electromagnetic casting problem. We look for a suitable set of electric wires such that the electromagnetic field induced by an alternating current passing through them makes a given mass of liquid metal acquire a predefined shape. The inverse electromagnetic casting problem is formulated as an optimization problem using a shape...
