Tool runout, cutting edge radius-size effect, and tool wear have significant impacts on the force of micro-milling. In order to predict micro-milling related performance, it is necessary establish a model including radius, wear. this study, an instantaneous uncut chip thickness (IUCT) considering nonlinear shear/ploughing coefficient cutting-edge friction embedded with flank width are respectiv...

The aim of this study was to analyze the force and deformation law an artificial frozen wall. Thus, frost heave coefficient introduced describe characteristics, wall regarded as a heterogeneous material whose properties changed in parabolic pattern with radius. elastoplastic stress displacement formulas non-uniform considering characteristics were derived according different strength criteria. ...

Recent investigations have shown that cell radius is a much better metric of RF coverage than area reliability. Given the maximum allowable path loss of the radio equipment and assuming a Hata path loss model, cell radius predictions are shown to be a monotonically decreasing function of the desired area reliability. A useful, technology independent nomograph is given that predicts the cell rad...

SolC. P. and T. Zaslavsky, The covering radius of the cycle code of a graph, Discrete Applied Mathematics 45 (I 993) 63-70. The cycle code of a graph is the binary linear span of the characteristic vectors of circuits. We exploit a connection between the covering radius of this code and minimum T-joins. We obtain a lower bound on the covering radius which is met with equality when the graph is ...

We report on observations of shear Alfvén waves radiated from a source of small transverse size, and the subsequent radial confinement of wave magnetic field energy within a cylindrical plasma. The radius of confinement lies between the kinetic regime of the bulk plasma and the inertial regime at the plasma edge; this radius is found to be a function of wave frequency. Numerical calculations us...

A new method is proposed to detect circular arcs. The detection of a circular arc includes the determination of its center, radius, length, and midpoint. The Hough transform is applied to detect circular arcs by using center and radius as parameters. A peak value in the parameter space of the Hough transform indicates the existence of a circular arc. The center and radius of the circular arc ar...

Let G be a 3-edge-connected graph of order n and radius rad(G). Then the inequality rad(G) ≤ 1 3 n+ 17 3 is proved. Moreover, graphs are constructed to show that the bound is asymptotically sharp.

This work explores the edge agreement problem of second-order nonlinear multiagent system under quantized measurements. Under the edge agreement framework, we introduce an important concept about the essential edge Laplacian and also obtain a reduced model of the edge agreement dynamics based on the spanning tree subgraph. The quantized edge agreement problem of second-order nonlinear multi-age...
