In modified atmosphere packaging (MAP) of horticultural produce, prediction of the evolution of gaseous O2 and CO2 concentrations inside packages is important to evaluate package performance and to reduce number of experimental trials needed to select packaging conditions. Mathematical modelling constitutes a useful tool in MAP design. A mathematical model for predicting oxygen (O2), carbon dio...

The advent of nanocrystalline metal oxide semiconductor permits microheater to be incorporated into integrated gas sensors to heat the sensing layer to a low temperature. The low temperature sensing allows the use of a relatively thin silicon membrane instead of zero Silicon membrane resulting into temperature uniformity across the entire active area (2mmx2mm) which in turn reduces the reliabil...

Finite element (FE) modelling of ultrasonic propagation using Comsol Multiphysics, or indeed any other FE software, inevitably involves large computations because two or three dimensional time-stepping models are needed to predict the behaviour of these kinds of travelling mechanical waves. Comsol can be used to create video of waves in these models, which is both attractive and informative. Un...

Evaluating the capabilities of GEANT4 code and COMSOL Multiphysics software can be achieved through coupling for an betavoltaic battery design. Spatial distribution deposited energy beta particles in semiconductor transducer has been simulated by using then, electron-hole pair generation rate obtained. Subsequently, output performances such as current-voltage (I–V) characteristics maximum elect...

ABSTRACT: Radiofrequency ablation (RFA) is the most promising, extensively studied and widely applied technique in clinical practice for the local treatment of solid tumors, viz., liver, kidney, lung, bone, etc. However, the application of RFA in treatment of breast cancer Radiofrequency ablation (RFA) is the most promising, extensively studied and widely applied technique in clinical practice ...
