ECAP of copper was successfully carried out at room temperature, using 90° tooling with route C in which the sample is rotated 180° along its longitudinal axis in this study, obtaining a total equivalent true strain ~4. Equiaxed grain with clarity boundaries and average grain size of 0.2μm formed after four passes.

The preforming process of 840 railway wheel was simulated by using commercial software MSC/Super Form. The distribution of the total equivalent strain and the metal flow track were analyzed.

Equal Channel Angular Processing of the medium carbon steel (0.45 wt.% C) was successfully carried out at 500 C with route C in which the sample is rotated 180 along its longitudinal axis in this study, obtaining a total equivalent true strain ~4. The microstructure evolution of ferrite and pearlite in ECAP was investigated by means of optical microscopy (OM) and transmission electron microscopy (TEM) .

The multiple deformations in the nonrecrystallization region significantly reduced εC,UFF, although the total equivalent strain for a given thermomechanical condition was higher than that required in single-pass deformation.

The total equivalent gate counts are reduced by 65.5%, maximum combinational path delay is reduced by 56.7%, and maximum net delay is reduced by 80.5% compared to conventional methods.

With protection for leukopenia and thrombocytopenia, a cyclophosphamide/thiotepa combination at very high doses maximizes total equivalent dose.

With no bone marrow protection, combinations with cisplatin offer a small improvement in total equivalent dose over therapy with the more active single-agents.

The estimated error of the total equivalent Poiseuille's resistance for the LAD artery computed from pruned data was 25.2% when compared with that computed from unpruned data.

The mentioned relationships are as follows: (l) the relation between the total equivalent orifice or the total resistance of mines and the ventilation system of mines; (2) the relation between the total equivalent orifi ce or the totol resistance of mines and the air pressure on certain cross sections of air flow and (3) the relation between the total equivalent orifice or the total resistance of mines and the mechanical ventilation pressure with the natural ventilation pressure.

Based on a large number of calculating indicator diagrams and total shear diagrams,, this paper induces a mathematical relationship between the over work ΔE_1~′and the value of the un-uniform torsional moment coefficent K′ produced by gas pressure. When the value of the over work caused by the reciprocating inertia force is added into the relationship, the total over work value results. The error of the total equivalent inertia of engines derived by the method of mathematical formula calculation instead...

Based on a large number of calculating indicator diagrams and total shear diagrams,, this paper induces a mathematical relationship between the over work ΔE_1~′and the value of the un-uniform torsional moment coefficent K′ produced by gas pressure. When the value of the over work caused by the reciprocating inertia force is added into the relationship, the total over work value results. The error of the total equivalent inertia of engines derived by the method of mathematical formula calculation instead of the prevailing method of table calculation can be controlled in the range of five per cent. An estimated formula for the weight of pistons and connecting rods is also presented in the paper by the use of the statistical method, so that a simple and relatively precise predication is provided for the predetermination of the torsional frequency of diesel engines.

A novel approach of modelling a switched DC-DC converter is presented. This method is very simple and suitable for simulation with program SPICE.
