An ion trap resonator, used for mass spectrometry, is investigated. Simulations are used to define the stabilization criterion of ion trajectories by optimization of the electrode configurations. The ion interactions are investigated and shown to help in reduction of ion-diffusion. Space charge effects simulate the induced voltages on pickup electrodes.

Uma das formas de se conseguir a multiplexação modal de informações em uma fibra óptica é através do uso do momento angular orbital (OAM). Neste trabalho exploramos a riqueza estrutural das fibras de cristal fotônico (PCF) para aprimorar a transmissão de modos OAM. Usamos o RF Module do software COMSOL Multiphysics para calcular os modos de propagação de uma PCF. Então, através do Livelink™ for ...

Ocean is the cornerstone in Earth’s system because the surface of the Earth is covered by ocean about 71%. Ocean also holds approximate 97% of the Earth’s water. Ocean is always moving and continuous. This study is focusing on the ocean movement in Southern Ocean which is located in the southernmost of the Earth. It can be called as Antarctica Ocean because it consists of the waters extending ...

The novel concept of distributing the food super chilled (partially frozen) in order to prolong the shelf life has been suggested in the project. The temperature of the distribution chain is envisaged to be +5C. The suggested application has the following advantages: 1) Partial thawing of the product in the distribution chain makes it easier to handle. 2) The unhealthy and labour-demanding ...

One of the crucial topics in this century is sustainable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of potential aquifer systems. Essential issues are convection, conduction and dispersion. This article focuses on Lauwerier’s problem. As an extension, it is suggested that beside ...
Dynamic Observation of Magnetic Particles in Continuous Flow Devices by Tunneling Magnetoresistance Sensors

Dynamic measurement of magnetic particles in continuous flow devices is made very difficult by the limitations imposed by the sensors themselves. Thus, certain sensor layouts are restricted to either number sensitive or spatial resolutive measurements of magnetic particles. We investigate different new strategies to increase the detection threshold and introduce designs accomplishing both: ...
COMSOL Multiphysics® as a Tool for Reducing Animals in Biomedical Research: An Application in Dermatology

In biomedical research the use of animal models gives rise to several ethical problems. COMSOL Multiphysics® may be used as a non-animal technique, very useful in overcoming all these concerns. In this presentation a particular application in dermatology is shown. Bioheat equation mode and diffusion approximation were used to design a theoretical model of blue LED light interaction with an ...

This paper presents an Analog to Digital Microfluidic Converter (ADMC) using passive valves and enabling the conversion of a continuous liquid flow into droplets for Electro-Wetting On Dielectric (EWOD) actuation. Valves calibration, geometry characteristics and losses reduction have been optimized using microfluidic application mode of COMSOL Multiphysics®.
Modeling Dispersal of Genetic Information in Structured Agricultural Landscapes with Partial Differential Equations

We present a model for plant dispersal in agricultural landscapes to evaluate the gene dispersal from genetically modified (GM) plants. Dispersal from seed and pollen is modeled with partial differential equations. In scenarios, we investigated the effect of roadside application of non-selective herbicides on dispersal of herbicide tolerant oilseed rape (HT OSR). We showed that OSR growing on ...
