The present paper describes a stator flux oriented control strategy using state space controllers. The optimal determination of different controllers'parameters (suitable placement of poles, continuous adapation of coefficients to the operating point of th ...
The dependence of the dispersion parameter α and of the time dependent diffusion parameter DH(tL) (estimated over a fixed diffusion length L) on annealing temperature Ta was investigated with elastic-recoil detection analysis (ERDA) in an undoped a-Si:H sa ...
The influence of strain on diffusion and nucleation has been studied by means of scanning tunneling microscopy and effective-medium theory for Ag self-diffusion on strained and unstrained (111) surfaces. Experimentally, the diffusion barrier is observed to ...
Richards' equation, the governing equation for single phase unsaturated flow in soil, is highly nonlinear and, consequently, is difficult to solve either analytically or numerically. The nonlinearity enters through the hydraulic functions, viz., the soil m ...
When InP is grown by chemical beam epitaxy on substrates patterned with ridges oriented along [110] with (111)B sidewall planes, the migration of In species on the surface changes direction with growth temperature. The movement is from the ridge to the val ...

Ag aggregation on Ag(111), Pt(111), and 1 ML Ag pseudomorphically grown on Pt(111), has been studied with variable temperature STM. These systems all have in common that dendritic patterns with trigonal symmetry rather than randomly ramified aggregates, wh ...
A new grid-based method is proposed for predicting the behaviour of colour printers. The method takes into account the varying density of dots as well as the light diffusion in the paper by defining at different intensity levels different colorimetric valu ...
We have used variable-temperature scanning tunneling microscopy to study the aggregation of two-dimensional Ag clusters on Pt(111). A transition from randomly ramified to dendritic fractal growth is observed in the diffusion-limited regime. Atomic-scale ob ...
We present a new method to determine surface diffusion constants using specular reflected thermal helium scattering. The specular reflected helium intensity is recorded in real time as a function of surface coverage of the adsorbate and surface temperature ...
