Introduction: Type II photodynamic therapy (PDT) is an experimental modality for cancer treatment based on the combined action of a photosensitizing drug (photosensitizer), a special wavelength of light and singlet oxygen (1O2) generation; the cell killing is caused by the reaction of cellular acceptors with 1O2. A mathematical model has been previously developed to incorporate the macroscopic ...

The extraordinary electromagnetic response of nanostructured material, usually made up of a metallic structures distributed in within a dielectric matrix has attracted a lot of interest in recent years. These materials are technically called metamaterial (MM) since they possess different properties from their constituent materials. Several applications of metamaterials have already been ...

The knowledge of the acoustical transfer paths in active noise control systems is very important for the performance of the system. Unfortunately, simulation is challenging since even simple configurations require comprehensive experience in physics and modeling. Two test setups were chosen for basic investigations on modeling, simulation and validation. The first results presented here are ...

A novel propellant technology requires extruding two formulations with differential burning rates (slow and fast) together as a multilayered propellant. This multilayered propellant is processed into a concentric cylinder configuration, in the form of slow-fast-slow with single perforation. The main challenge originated from the different path lengths between the inner and outer sections of the ...

Previous to the present work, a formal calculation was approved [1,2] to support the operation of the High Flux Isotope Reactor (HFIR) Horizontal Beam-Tube 1 of 4 (HB-1). The present calculation [3,4] repeats the previous work using COMSOL Multiphysics® software and extends the analysis to cover a broader range of coolant flow. In addition, this new calculation expands the analysis much further ...

To obtain large transparent ceramic samples, we optimized the drying step process using COMSOL Multiphysics®. Indeed, green body's drying in a climate chamber is the critical step when large size and complex shape samples are needed. Then we obtained 75 mm diameter and 10 mm thickness highly transparent spinel ceramics.

Fluid-structure interaction (FSI) refers to a class of problems in which the motions of fluid and solid are coupled. FSI is of great significance in many applications such as aero-elasticity, biomechanics, and design of various engineering systems. Typically, the multiphysics involved in the FSI problems render them too complex to solve analytically, necessitating the use of numerical ...

We describe the thermal modeling of a crate hosting boards with Associative Memories (AM) designed for the Fast Tracker Trigger (FTK) system of the ATLAS detector at the CERN Large Hadron Collider. FTK is a highly paralleled hardware system designed to provide global tracks reconstructed in the inner detector. The hardware system is based on AM for pattern recognition and fast FPGAs for track ...

This work aims at the modelling of a 5 cm^2 Direct Methanol Fuel Cell (DMFC) with mixed serial/parallel serpentine flow fields in terms of current/voltage behavior. One of the main challenge to overcome consists on lowering the so-called methanol cross over from the anode through the polymer membrane to the cathode that is responsible for mixed-potential formation at the cathode where both ...

Recent studies report problems related to premature aging and degradation of high-voltage polymeric insulators. Corona activity, which is induced in areas of high electric field levels, is considered one of the leading causes of these problems. The insulator operation under adverse conditions including rain, fog, dew and pollution is affected by these key factors that modify the electric field ...
