Exhaust noise must meet legislation targets, customer expectations and cost reduction which call for design optimization of the exhaust systems in the design phase. One solution is to use 3 dimensional linear pressure acoustics and calculate the transfer matrix of the muffler. The ... 詳細を見る

This paper presents an analysis approach of multicondcutor quasi-TEM lines transmission interconnect in a single dielectric region and multimode waveguides using the finite element method (FEM). FEM is especially suitable and effective for the computation of electromagnetic fields in ... 詳細を見る

Introduction of silicone hydrogel contact lens materials provided products of unprecedented capability to deliver oxygen to the eye during wear. One additional material characteristic of interest is the material’s permeability to ions. This paper discusses descriptive tools and ... 詳細を見る

A compression driver is a certain type of electrodynamic loudspeaker which has a phase plug with slits in front of the diaphragm. The slits are narrow enough that the so-called viscothermal effects are of significant importance. In this paper a 2D axisymmetric finite element model of a ... 詳細を見る

Radio Frequency MEMS devices have emerged to overcome the problem of high losses associated with semiconductors at high frequencies. A tunable MEMS capacitor is a micrometre-scale electronic device whose capacitance is controlled through different actuation mechanisms which govern the ... 詳細を見る

New drug discovery and development is costly; of all compounds investigated for use in humans, only a small fraction is approved for treatments around the world. The pharmaceutical industry has started switching from molecular drugs to protein-based drugs due to high specificity, ... 詳細を見る

Materials and their related properties are intrinsically fundamental to the creation, development and solution of viable exploratory models when using numerical analysis software. In many cases, simply determining the location, availability and relative accuracy of the necessary material ... 詳細を見る

Terahertz (THz) technology has been receiving expanding interest in the recent years due to its rich scientific and potential application. For instance, a variety of semiconductor phonons resonate in the THz range; macro-biomolecules have unique fingerprint lines in the THz range; less ... 詳細を見る

A new method is proposed to study battery thermal behavior under nature convection condition, especially focusing on temperature rising and inhomogeneity of battery. Using porous electrode theory, an electrochemical and homogenization heat source thermal coupling model and an ... 詳細を見る

Finite element modeling of three-phase induction machines requires the solution of coupled circuit and field equations. This work aims to solve this problem using a strong coupling approach. This work includes circuit field coupling and proper air-gap meshing, using the AC/DC Module of ... 詳細を見る
