AC loss curves measured for the same conductors at SULTAN (CRPP) and at University of Twente (UT) in higher and respectively lower frequency range are compared to draw consistent results. From the unified curves, the coupling time constant (n tau) to be us ...
The paper proposes a new method to determine the tooth cogging force in a brushless DC (BLDC) motor which is used in a hard-disk application. This force might be a source of tooth vibrations and motor noise. In the new method, the permanent-magnet (PM) pol ...
In a recent paper [R. Finn, Phys. Fluids 18, 047102 (2006)] the attention has been drawn on the tension component perpendicular to the solid surface that results from Young's law. Considering the problem of a solid sphere floating in zero gravity, it has b ...
The MilliNewton force sensor is sensitive to lateral forces, in the direction of the length of the beam. The degree of sensitivity of such sensors depends essentially on the size of the force centring ball and the length of the cantilever beam. On the othe ...
The sustainable development of rivers requires a knowledge on the three-dimensional mean flow field and the turbulence in complex morphologies. In a future, the computational capacity will be sufficient to simulate numerically the fine details of the flow. ...
Cell divisions that create daughter cells of different sizes are crucial for the generation of cell diversity during animal development. In such asymmetric divisions, the mitotic spindle must be asymmetrically positioned at the end of anaphase. The mechani ...
In modern robots and industrial machine tools, acceleration times begin to prevail over cruising times. This paper demonstrates the important relations between acceleration shape and the various characteristics of a drive system. These characteristics are ...
Existing unreinforced masonry (URM) buildings, many of which have historical and cultural importance, constitute a significant portion of existing buildings around the world. Recent earthquakes have shown the vulnerability of such URM buildings. This thesi ...
In the framework of rockfall trajectory modelling, the bouncing phenomenon occurring when a rock block impacts with the slope surface is the most difficult to predict, owing to its complexity and its very limited understanding. Up to now, the rebound is co ...
Plasma inhomogeneity caused by standing-wave effects in rf parallel plate reactors can be removed if one of the electrodes is replaced by a shaped electrode. The proposed shape is calculated using Maxwell's equations in vacuum. In this solution, the electr ...
