Application of Machine Learning and Swarm Intelligence to Wastewater Treatment

, Cascade Clean Energy, Inc., US

Swarm intelligence (SI) is a branch of artificial intelligence, which has been existing in nature among grouping and activities of animals, birds, ants, fish or even microbes. Swarm Intelligence is the collective behavior of decentralized, [...]

Two Examples of Nonclassical Fullerenes with Dodecahedral Structure

Sanchez Bernabe F., Universidad Autónoma Metropolitana, MX

Two nonclassical fullerene are presented. The first one contains heptagonal faces, besides pentagons, and hexagons.This example contains 420 carbons. There are 60 heptagons. The number of hexagons is 80, and finally, we have 72 pentagons. [...]

Molecular Modeling of Silicon-Based Anode Material for High-Performance Lithium-Ion Batteries

Schweizer S., Low J.J., Subramanian L., Scienomics, US

Lithium(Li)-ion batteries are widely used in portable electronic devices. Their use as energy storage system in other important industrial fields - such as electric vehicles, wind turbines, or photo voltaic plants - is limited by [...]

Recent Advances in Industrial Coarse-Grained Method Development & Modeling

Handgraaf J.-W., Fraaije J.G.E.M., Culgi, NL

In present day the crux of performing coarse-grained simulations is the actual parameterization of the (molecular) interactions and the validation of the outcome of a simulation. In a recent effort we have work on the [...]

Materials data management in research & development: improving innovation and product liability

Ehrig T., Klepsch L., IMA Materialforschung und Anwendungstechnik GmbH, DE

Challenge Companies produce a huge amount of notes and tables, especially for their research and development processes. A lot of different tools are used to store such information:  Note-taking apps, like Mind-Mappers, One-Note, ... [...]

Simulation of Breakdown Voltage Enhancement in AlGaN/GaN HEMTs with Double Passivation Layers

Horio K., Hanawa H., Shibaura Institute of Technology, JP

It is well known that the introduction of field plate increases the breakdown voltage of AlGaN/GaN HEMTs [1, 2]. However, it increases the parasitic capacitance, leading to the degradation of high-frequency performance. As another way [...]

Positioning of Thermal Via Regions for Reducing Hotspot Temperature in 3D ICs

Maj C., Galicia M., Zajac P., Napieralski A., Lodz University of Technology, PL

The increase of the processor performance is the most desired result of technology evolution. As today’s technology reaches its limits, some other methods has to be developed to uphold performance increase. One of the promising [...]

Effects of Buffer Acceptors on Breakdown Voltages of AlGaN/GaN HEMTs with a High-k Passivation Layer

Kawada Y., Hanawa H., Horio K., Shibaura Institute of Technology, JP

AlGaN/GaN HEMTs are now receiving great interest for application to high-power microwave devices and high-power switching devices. However, the breakdown voltage is known to be greatly lower than that theoretically predicted. To improve the breakdown [...]

Reduction in Lags and Current Collapse in Field-Plate AlGaN/GaN HEMTs with High Acceptor Density in a Buffer Layer

Saito Y., Tsurumaki R., Noda N., Horio K., Shibaura Institute of Technology, JP

We make a two-dimensional transient analysis of field-plate AlGaN/GaN HEMTs with a semi-insulating buffer layer, where a deep acceptor above the midgap is considered. It is studied how the deep-acceptor density and the field plate [...]
