TL;DR: In this article, a general approach to magnetic losses in soft magnetic composites (SMC) is discussed, based on the statistical theory of losses (STL) and the related concept of loss separation is extended to the case of granular heterogeneous materials.
Abstract: A general approach to magnetic losses in soft magnetic composites (SMC) is discussed. It is applied to exciting conditions typical of applications, where the induction waveform is most frequently nonsinusoidal. The standard predicting approach, based on the statistical theory of losses (STL) and the related concept of loss separation, is extended to the case of granular heterogeneous materials. As a starting point, the classical loss component is calculated, taking into account that in small enough samples the measured loss is independent of the specimen cross-sectional area, because of negligible grain-to-grain (macroscopic) eddy currents. The loss separation is then performed under the conventional sinusoidal induction regime and the STL is used to identify a limited set of parameters, associated with the prediction of the excess loss, by which the energy loss under distorted induction can be predicted. Significant predicting examples are provided, regarding two different SMCs, where the induction waveform is either triangular or distorted by introduction of a third harmonic component.

TL;DR: In this article, a series of boron dipyrromethene derivatives bearing an electron-donating 4-(dimethylamino)phenylethynyl group and an electronwithdrawing 4-nitrophenyl group in the opposite 2-and 6-positions have been synthesized by Knoevenagel condensation followed by sequential Sonogashira coupling reactions.

TL;DR: In this paper, a vibrating string, modelled by the wave equation, with an interior mass is considered, and a trajectory tracking problem is solved using a new type of controllability.
Abstract: A vibrating string, modelled by the wave equation, with an interior mass is considered. It is viewed as a linear delay system. A trajectory tracking problem is solved using a new type of controllability.

07 Nov 2009TL;DR: A new classification of work in this area is presented, i.e. work related to the theory and/or applications of image analysis filters, systems, or algorithms based on mathematical morphology that are adaptive w.r.t. to space or intensity or use any other adaptive scheme.
Abstract: In this paper we briefly overview emerging trends in ‘Adaptive Morphology’, i.e. work related to the theory and/or applications of image analysis filters, systems, or algorithms based on mathematical morphology, that are adaptive w.r.t. to space or intensity or use any other adaptive scheme. We present a new classification of work in this area structured along several major theoretical perspectives. We then sample specific approaches that develop spatially-variant structuring elements or intensity level-adaptive operators, modeled and implemented either via conventional nonlinear digital filtering or via geometric PDEs. Finally, we discuss some applications.

TL;DR: In this paper, the authors present a new modeling paradigm for computing the complete failure of metal frames by combining the stress-resultant beam model and the shell model, which takes into account elastoplasticity with strain-hardening and strain-softening, as well as geometrical nonlinearity.
