On bandwidth enhancement of compact multiple antennas with parasitic decoupling

Recently, it has been shown that a parasitic element can be used to fully decouple closely spaced antennas. However, the decoupled antennas suffer from narrow bandwidth, as compared to the bandwidth of isolated single antennas, which is also the case for other decoupling methods, such as multiport conjugate match and neutralization line. In this paper, we investigate the potential in bandwidth enh

Efficient crystal plasticity simulations of microstructure evolution

One of the common tools for studying the deformation behavior of the microstructure in polycrystalline materials is crystal plasticity models. These are used to describe texture evolution and hardening due to crystallographic slip. A drawback when using crystal plasticity models is that the calculation of the slip requires solving a set of stiff differential equations for each grain in the microst

Process Oriented Ergonomics - The Ergonomics of the Future? A Case Study of Integrated Ergonomics at an Engine Assembly Plant

Ergonomics are, in most cases, focusing on the human being when evaluating assembly system designs. This results in the human performance being expressed isolated from the technical environment. On the other hand, technicians are prone to concentrate on the hardware. These conditions underline the need to pursue a more integrated evaluation and design procedure in order to avoid the drawbacks of t

Anionic and cationic block copolymers as durable electrolyte membranes

Durable block copolymers combining ionic and non-ionic blocks hold a great promise as membrane materials in next-generation fuel cells and batteries. With a proper macromolecular design, these copolymers self-assemble to form ordered nanostructures in which ion and water transport is facilitated over a wide range of conditions. For example, membranes based on sulfonated block copolymers typically
