The consequences of hip fracture and femoral fracture are widely known. The mechanical strength of the femur varies in every person, but it is possible to predict the mechanical resistance with parameters like density, dimensions and mineral content. This paper uses different models and empirical studies to determine the mechanical properties of the human femur, developing isotropic and ...

Imaging of tissue with near-infrared diffuse optical tomography is emerging as a practical method to map hemoglobin concentrations within tissue for breast cancer detection and diagnosis. The accurate recovery of images by using numerical modeling requires an effective image reconstruction method. We illustrate a comparison between two widely used reconstruction methods using finite element ...

Vein visualization systems such as the VeinViewer are vein-contrast enhancement devices that use an infrared camera to highlight blood or the underlying vasculature and project the image in real time onto the skin. Understanding the light propagation in a realistic skin model is critical, but only a few computational models have been developed to account for this particular system. We have ...

Worldwide attention in the computational modeling and simulation of the human intestine is increasing in order to help understand its complex behavior and improve health. Computational fluid dynamics is an essential tool to understand the mechanics and transport phenomena of the human intestine, thereby advancing the diagnosis and treatment of gastrointestinal related diseases. The aim of this ...
Improving Detection Sensitivity for Nanoscale Targets Through Combined Photonic and Plasmonic Techniques

Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection sensitivity may not be sufficient when the size of the detection target is in nanoscale. To change this, we ...

CFD simulations were carried out to predict the convective heat and mass transfer coefficients in the rice bed, and correlations were developed for the convective heat and mass transfer coefficients as a function of drying air flow rate. The developed correlations were used to extend the model developed by ElGamal et al. (2013) for thin-layer rice drying to volumetric heat and mass transfer in a ...

During peripheral intravascular interventions one of the main issues is the correct deployment of the guidewire (GW) to the anatomical site which has to be treated, often supported by a microcatheter. There is a trade-off between the microcatheter flexibility and its push-ability to be able to reach the anatomical site. The catheter design has been defined with 2 transition zones. A parametric ...

This work aims to investigate the behaviour of a simple interdigital sensor structure for glucose monitoring in response to distortions in the skin-topology and differences in skin undulation during use. The study then extends to consider a flexible sensor structure which is better able to contour to the skin variations. The simulation work shows that skin distortions and undulation ...

Retinitis Pigmentosa (RP) and Age-related Macular Degeneration (AMD) are diseases causing blindness in a large number of people. In this type of degenerative disease, mostly the photoreceptors are damaged. Thus attempts have been made to electrically stimulate the surviving inner retinal neurons and retinal ganglion cells (RGC) in order to restore vision. In this paper, the electrode-tissue ...

In this paper, the gross electrical characterization of biological cells on porous substrate is analyzed using COMSOL Multiphysics®. Dynamic electrical characterization during cell growth is used as a non-invasive and label-free technique to understand the growth kinetics of cells. It is observed from the COMSOL simulation that the percentage change in the current density is greater in porous ...
