Impact of pressure anisotropy on tokamak equilibria and the toroidal magnetic precession

Jonathan Graves, Wilfred Anthony Cooper, Martin Jucker

Using a generalized anisotropic tokamak equilibrium and an exact guiding centre drift formulation, the effect of parallel and perpendicular anisotropy on the toroidal precession drift is investigated. Signiﬁcant differences between parallel and perpendicul ...

Orthogonal fluxgate type magnetic microsensors with wide linear operation range

Ozge Zorlu

This thesis presents a study on the development of microfabricated fluxgate type magnetic sensors operating within a wide linear operation range. Fluxgate type magnetic sensors are powerful devices due to their high sensitivity, low offset, and high temper ...

Improvement of Orientation Estimation in Pedestrian Navigation by Compensation of Magnetic Disturbances

Phillip Tomé, Okan Yalak

Over the last few years there has been a growing interest in the domain of pedestrian navigation, stimulated by the increasing demand for Location Based Services. Pedestrian Dead Reckoning (PDR) based on MEMS sensors has been at the heart of most high-end ...

Magnetic correlations at graphene edges: Basis for novel spintronics devices

Oleg Yazyev

Magnetic zigzag edges of graphene are considered as a basis for novel spintronics devices despite the fact that no true long-range magnetic order is possible in one dimension. We study the transverse and longitudinal fluctuations of magnetic moments at zig ...

Magnetic anisotropy of paramagnetic and ferromagnetically ordered state of single crystal BaVSe3

László Forró, Helmuth Berger, Ana Akrap

Anisotropic magnetism of single crystal BaVSe3 was Studied for the first time by the combination of the susceptibility and torque methods. As reported previously for polycrystalline sample, BaVSe3 undergoes ferromagnetic ordering below 43 K. Well above fer ...

Innovative devices for electron spin resonance spectroscopy on small samples

Malika Bouterfas

Within the past few years, the field of Electron Spin Resonance has become an important tool in physical, chemical and biological research. However, in many cases its usefulness is limited by the sensitivity of the experimental setup. A typical example is ...

Optimal Data Fusion for Pedestrian Navigation based on UWB and MEMS

Bertrand Merminod

Indoor pedestrian navigation is probably a very challenging research area. In this context, an optimal data fusion filter that hybridises a large set of observations: angles of arrival (AOA), time differences of arrival (TDOA), accelerations, angular veloc ...

Full on-chip nanoliter immuno-assay by geometrical magnetic trapping of nanoparticle chains

Martinus Gijs, Caroline Vandevyver, Frédéric Lacharme

We propose an original concept to perform a complete on-chip sandwich immunoassay on magnetic nanoparticles that are self-assembled in chains in a uniform magnetic field. The magnetic chains are retained over periodically enlarged cross sections of a micro ...

The role of the density gradient on intermittent cross-field transport events in a simple magnetized toroidal plasma

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Benoît Labit, Christian Gabriel Theiler, Mario Ludovico Podesta, Francesca Maria Poli

Intermittent cross-field particle transport events (ITEs) are studied in the basic toroidal device TORPEX [TORoidal Plasma EXperiment, A. Fasoli et al., Phys. Plasmas 13, 055902 (2006)], with focus on the role of the density gradient. ITEs are due to the i ...

Delta-sigma loop based on charge pumping in SOI optical sensor

Maher Kayal, Jean-Michel Sallese, Louis Harik

In this paper, the partially depleted SOI phototransistor has been used as a light intensity sensor. A pixel implementing the technique elaborated in [1] was designed and implemented on SOI technology. The circuit implements a first order delta-sigma modul ...
