Simulation of Auxin Accumulation and Transport in a Plant Root

M. A. Akhmanova [1], M. Fendrych [1], J. Friml [1]
[1] Institute of Science and Technology Austria, Klosterneuburg, Austria

Plant roots have an outstanding ability to grow in the direction of gravity or nutrients. Bending of the root tip in the preferred direction is achieved by asymmetric cell growth on the opposite sides of the root, dictated by asymmetrical distribution of the hormone auxin. Increase in ...

[2] Amphos 21 Consulting S.L., Barcelona, Spain & Université Toulouse III, Toulouse, France

Reactive transport models (RTM) that couple physical and chemical processes are commonly used to solve a large variety of problems in the environmental industry. There are a series of codes designed to solve this kind of problems. However, their use requires typically much effort due to ... Read More

CFD Investigation of Cross Bubbly Flow through a Bubble Column with Rectangular Geometry

N. M. Musa [1], D. Kuvshinov [1], P. Rubini [1],
[1] The University of Hull, Hull, East Yorkshire, United Kingdom

Impact of human activities on the climate is evident, and the recent anthropogenic production and discharge of greenhouse gases into the atmosphere is highest in history. The current climate change have had worldwide influence on human and natural systems for example; global warming, ... Read More

[3] Óbuda University Doctoral School of Material Science & Technology, Budapest, Hungary

The topic of my work is modeling of a multimodal waveguide microprobe which is suitable for deep brain infrared stimulation. The goal of the research is the investigation of the therapeutic effect of optical IR excitation on biological active substances. In the physical model I ... Read More

Multiphysical Simulation of Moved Data Cable

M. Raum [1]
[1] Friedrich-Alexander Universität, Erlangen, BY, Germany

In general this thesis is about the effects of mechanical stress on data cables in moved applications. If a data cable is loaded with different kind of forces and used within high frequency applications it is possible, that the geometrical changes may have an impact on the electrical ... Read More

Keep it Simple and Learn More - On a Stationary Study of a Time-Dependent Problem

B. Baumann [1], J. Schwieger [1, 2], U. Stein [1], M. Wolff [1],
[1] Hamburg University of Applied Sciences, Hamburg, Germany
[2] University of the West of Scotland, Paisley Campus, United Kingdom

Today’s driver hardware for High-intensity discharge (HID) lamps is bulky, expensive and not particularly energy-efficient. A downscaling of the devices seems possible by increasing the operation frequency from typically 400 Hz to some hundred kilohertz. However, efforts to design high ... Read More

Impact of the Forces due to CLIQ Discharges on the New HL-LHC Beam Screen

M. Morrone [1], C. Garion [1],
[1] CERN, Geneva, Switzerland

In the framework of the high luminosity large hadron collider (HL-LHC) project, important upgrades will take place by 2024 including the installation of new superconducting magnets in which new beam screens will be placed. The beam screen is an octagonally shaped pipe inserted into the ... Read More

Modeling and Simulation of Hydrogen Generation in Membrane Reactor via Steam Octane Reforming

N. Ghasem [1], A. Y. Alraeesi [1],
[1] UAE Univeristy, Alain, United Arab Emirates

Various hydrocarbon compounds have been converted into pure hydrogen by using a catalyst and a palladium membrane in one reactor (PMR) in a one-step process where the reaction proceeds to almost complete conversion. Octane is converted into pure hydrogen using of a palladium membrane ... Read More

Dynamic Simulation of a Coaxial Magnetic Gear Using Global ODE's and the Rotating Machinery, Magnetic Interface

M. Ostroushko [1], W. Zhang [1], W. M. Rucker [1],
[1] Institute of Theory of Electrical Engineering, University of Stuttgart, Stuttgart, Germany

The coaxial magnetic gear is a good alternative to classic mechanical gears. The magnetic gear has high mechanical durability, overload protection and lower noise, than a mechanical gear [1,2]. A static model of a magnetic gear [3,4] is used for simulation of the magnetic fields and ... Read More

Simulation and Visualisation of Shielding Gas Flows During Wire-Arc Additive Manufacture

I. Bitharas [1], A. Moore [1],
[1] Heriot-Watt Univerisity, Edinburgh, UK

One of the challenges associated with the wire-arc additive manufacture (WAAM) of metals is to provide adequate inert gas shielding, not only for the molten pool, but also for the long reactive metal surface that follows it. For Ti-6Al-4V, it has been shown that increased levels of ... Read More
