1. It is feasible to focus and guide nanoparticles with permanent magnets and ferromagnetic particles to achieve clinically significant olfactory dosages. 2. With appropriate magnetophoretic guidance and selective drug release, an olfactory delivery efficiency of more than 20% can be achieved. 3. The optimal particle size range for magnetophoretic guidance is 10−15 µm.

Although cardiac arrest may be statistically insignificant event financial and more important emotional costs in such cases are quite devastating. In this paper we study the effects of multiple grounding pads. Namely, we believe that by placing multiple pads in the lower abdominal part we would be able to decrease the current density that would be dissipated to fetus and amniotic liquid. ...

ELENA is a small cooler decelerator ring at CERN which will be built to increase substantially the number of usable antiprotons delivered to experiments for studies with antihydrogen and antiprotonic nuclei. COMSOL Multiphysics® software has been used to completely model the ELENA electron cooling device in 3D. We have taken advantage of the different physics-based modules of COMSOL ...

β heat treatment of Uranium rods is carried out for randomization of oriented grains (called texture) developed during hot rolling or hot extrusion operation. During this process, Uranium rods undergo heating of up to 740 Deg C followed by water quenching. The objective of this work is to see the feasibility of direct heating technique for heat treatment application. At present, heat treatment ...

Outline of presentation: In electromagnetic technology applications the finite element method is very well suited for a wide range of problem types For many cases, in particular when inhomogeneous materials having complex properties are involved as well as when multiphysics couplings are essential, it is the only option available The somewhat unfavourable performance scaling with problem ...

The main design goals for electromagnetic actuators are force, dynamic behaviour, and energy efficiency. In the development of valves for electronic brake systems at Continental Automotive Systems, COMSOL multiphysics is used in order to assess all three aspects. For instance, the response to a voltage step involves the calculation of time-dependent magnetic fields, of eddy currents, and of ...

Tunnels and their detection have been a problem in warfare since the ancient world. Recent events have highlighted the ongoing problems of tunnels and the difficulties in locating them, not only in military situations, but also in law enforcement and homeland security applications as well. Electromagnetic and acoustic or seismic techniques may provide the significant advantage of a mobile non ...

The Levitron offers an interesting demonstration of natural magnetic levitation using permanent magnets. It is composed by a small magnetized top and a circular magnetized base with a hole on its center. The top is placed in an area where magnetic field configuration and gyroscopic torques allow the existence of a locus of stable equilibrium. In this paper, we intend to dimension and realize a ...

This paper presents the Finite Element Method technique for predicting performance of Induction motor having Electric and Magnetic asymmetry for rotor cage due to some broken rotor bars. The motor parameters like magnetic vector potential, flux density, surface currents have been determined very precisely by carrying out two dimensional quasi static, transient analysis and by using one of the ...

COMSOL, adding SPICE® elements into its FEM, gives the possibility of a direct modeling of oscillators: triode and load are FEM described while all the other components of the circuit are just simulated using SPICE®. The modeling is not a straight application of any module but needs the previous computation of the conductivity of the beam through the PDE interface. This paper is a bench mark ...
