Musculoskeletal mineralized tissues (MMTs), e.g. bone, are hierarchical composite materials. Their effective elastic properties at different scales are of interest for computational studies of the MMT’s response to mechanical loading but also to realistically simulate implant osseointegration. We combine multi-scale and multi-modal experimental techniques with mathematical modelling of MMTs ...

A resonant MEMS sensor for viscosity and mass density measurements of liquids was modeled. The device is based on Lorentz-force excitation and features an integrated piezoresistive readout. The core sensing element is a rectangular vibrating plate suspended by four beam springs. The liquid surrounding the plate influences the resonant behavior of the system. Thus, evaluating the properties of ...

Superparamagnetic nanoparticles have a wide range of applications in modern electric devices. Recent developments have identified them as components for a new type of magnetoresistance sensor. We propose a model for the numeric evaluation of the sensor properties. Based on the solutions of the Landau-Lifshitz-Gilbert equation for a set of homogeneously magnetized spheres arranged in highly ...

This paper is a part of a study on energy piles for heating and cooling of buildings. Energy piles are used for two reasons: (1) to transfer structural loads to foundation soils, and (2) to transfer heat from foundation soils to the building for space heating in winter time and for cooling purposes in summer time by transferring heat from the building to the foundation soils. The efficiency of ...

Ferrimagnetic based, coaxial nonlinear transmission lines (NLTLs) provide a means to generate sub-nanosecond risetime pulses (from nano-second input pulses) or megawatt level high power microwave oscillations, depending on the geometry, material, and external bias fields. This investigation uses the commercially available, finite element solver COMSOL to provide insight into pulse behavior. ...

This paper reports on the application of COMSOL Multiphysics’ Richard\'s Equation Interface in the assessment of irrigation moisture sensors for detecting the level of water saturation in a spatial variably saturated soil. The Richard\'s Equation (in COMSOL) provides the interface which automates the van Genuchten equation. A hypothetical soil column 4m by 4m was set up with seven irrigation ...

The main reason for stent implantation is to provide mechanical support to the arterial wall. So it is important to consider the different mechanical properties of different stent materials while studying the stent implant’s efficacy. The present study gives a comparative overview of mechanical aspects of different stent materials which are most commonly used in angioplasty. Deformation ...
