Electrical effects in winding of large electrical ac machines application to advanced large size DFIM

To meet the electrical grid's demand on pump power variation, GE Renewable Energy develops since 10 years variable speed machines (also called Doubly Fed Induction Generators or DFIG). Within turbogenerators, the phenomenon of circulating currents in Roebe ...

Out-of-plane transport in ZrSiS and ZrSiSe microstructures

Philip Johannes Walter Moll, Maja Deborah Bachmann, Kent Robert Shirer

A recent class of topological nodal-line semimetals with the general formula MSiX (M = Zr, Hf and X = S, Se, Te) has attracted much experimental and theoretical interest due to their properties, particularly their large magnetoresistances and high carrier ...

Deformation of the moving magnetic skyrmion lattice in MnSi under electric current flow

Henrik Moodysson Rønnow, Ivica Zivkovic, Jonathan White, Zhuo Quan Im

Topological defects are found ubiquitously in various kinds of matter, such as vortices in type-II superconductors, and magnetic skyrmions in chiral ferromagnets. While knowledge on the static behavior of magnetic skyrmions is accumulating steadily, their ...

Radiation Performance of Highly Miniaturized Implantable Devices

Denys Nikolayev

Miniature wireless implantable bioelectronics provide powerful capabilities for biotelemetry, therapeutics, and neural interfacing. These technologies rely on antennas to communicate with external receivers, yet existing systems suffer from poor radiation ...

Potential erosion capacity of gravity currents created by changing initial conditions

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Jessica Zordan

We investigate to what extent the initial conditions (in terms of buoyancy and geometry) of saline gravity currents flowing over a horizontal bottom influence their runout and entrainment capacity. In particular, to what extent the effect of the introducti ...

Mass loss of density currents travelling over pourous bed

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sara Venuleo

Polluted liquids leaking from their storages over the surrounding gravel beds or oil spilling into aquifers, are examples of gravity currents moving over a porous terrain. Density-driven flows provoked by saline or temperature differences or turbidity curr ...

Highly anisotropic interlayer magnetoresitance in ZrSiS nodal-line Dirac semimetal

Oleg Yazyev, Quansheng Wu, Shengnan Zhang, Xiaoqiang Wang

We instigate the angle-dependent magnetoresistance (AMR) of the layered nodal-line Dirac semimetal ZrSiS for the in-plane and out-of-plane current directions. This material has recently revealed an intriguing butterfly-shaped in-plane AMR whose origin is n ...

Ontology-Based Resource Allocation for Internet of Things

Damiano Nunzio Arena, Zeinab Nezami

The Internet of Things has revolutionized the lifestyle in all aspects. Considering the huge number of connected objects and the plethora of real-time services, edge computing approaches have emerged. Resource allocation is one of the most important challe ...

Modelling of non-linear edge harmonic oscillations and the effect of non-axisymmetric magnetic coils

Jonathan Graves, Wilfred Anthony Cooper, Daniele Brunetti, Andreas Kleiner, Guillermo Bustos Ramirez

Quiescent H-mode (QH-mode) operation is highly desirable relative to the well known H- mode operation because it allows for high energy density in the core as well as potentially im- proved confinement of energy and particles. A feature of QH-mode is that ...

In situ observation of picosecond polaron self-localisation in alpha-Fe2O3 photoelectrochemical cells

Ludmilla Steier

Hematite (alpha-Fe2O3) is the most studied artificial oxygen-evolving photo-anode and yet its efficiency limitations and their origin remain unknown. A sub-picosecond reorganisation of the hematite structure has been proposed as the mechanism which dictate ...
