Capacitive MEMS (Micro-Electro-Mechanical Systems) accelerometers may be directly soldered to the printed circuit board by an array of solder balls. Differences in the thermal expansion coefficients of the pertinent materials cause deformations of the accelerometer under temperature change. This may cause a relative movement of the sensing masses with respect to the sensing electrodes, resulting ...

Partial differential equations have recently become popular and useful tools for several image processing tasks such as image de-noising and segmentation.In this work, we implement a unified image de-noising and segmentation approach which is based on a nonlinear diffusion equation with a reactive term for achieving edge preserving smoothing and segmentation. This model is highly nonlinear and ...

During the past 50 years, Computational Science has developed as its own branch of mathematics. This development was mainly initiated by the progress of modern computers. Todays modeling of physical phenomena must not only account for the computational time but also the time engineers spend on setting up the computation. This in turn has introduced new fields, such as human interaction, to ...

As biologists uncover the structural and functional complexity of living organisms, it is increasingly clear that mathematical models are needed to synthesize experimental data and predict biological responses to external stimuli. Bioengineers are well-suited to develop such models and to add mechanics, fluid flow and other physical cues to the understanding of biological structure and ...

In this paper we present a novel approach for modeling spatial distributed bio- chemical and environmental processes like the growth of plants and the related biochemical reactions. The physical phenomena like flow and mass transport can be described by fluid dynamics equations, but for effects like growth rates often no analytic models are available. However, in many cases experts have knowledge ...

Augmented reality is predestined for visualization of electromagnetic fields in air or inside transparent matter. Real existing objects are studied and invisible electromagnetic fields are added as virtual objects. Hence, experts as well as students are able to connect electromagnetic fields easily with studied objects. They can concentrate on physical effects instead on reading figures. Here, an ...

Zebrafish development of the dorsoventral axis relies on the spatiotemporal distribution of Bone Morphogenetic Protein (BMP) signaling, which is regulated by numerous secreted molecules such as Tolloid, Sizzled, and Chordin. The rich dorsal/ventral patterning network must achieve both spatial precision in the patterning of downstream targets and confernspatial precision at distinct time points in ...

Partial differential equations which exhibit solutions that are spatial temporal patterns are often found in biological and chemical systems, e.g. when describing pattern formation in reaction-diffusion systems.Special classes of such patterns are relative equilibria and relative periodic orbits, which are solutions that in an appropriately co-moving frame of reference are stationary and ...

The flux of a fluid in permeable media can be modelled using a continuous. To link the real system with the continuous model is mandatory to realize a suitable average of the equations and of the variables. The dispersion term comes from this averaging but it is not only a mathematical product of the modelling. The dispersion is due to the intrinsic geometry of the permeable media that forces ...
