Abstract:

As a solution to mid-air haptic actuation with strong and continuous tactile force, Magnetic Rendering is presented as an intuitive haptic display method applying an electromagnet array to produce a magnetic field in mid-air where the force field can be felt as magnetic repulsive force exerted on the hand through the attached magnet discs. The magnetic field is generated by a specifically designed electromagnet array driven by direct current. By attaching small magnet discs on the hand, the tactile sensation can be perceived by the user. This method can provide a strong tactile force on multip

Abstract:

The 1-D 1/2-spin XXZ model with staggered external magnetic field, when restricting to low field, can be mapped into the quantum sine-Gordon model through bosonization: this assures the presence of soliton, antisoliton and breather excitations in it. In particular, the action of the staggered field opens a gap so that these physical objects are stable against energetic fluctuations. In the present work, this model is studied both analytically and numerically. On the one hand, analytical calculations are made to solve exactly the model through Bethe ansatz: the solution for the XX + h staggere

Abstract:

The magnetic carpet is defined to be the small-scale photospheric magnetic field of the quiet Sun. Observations of the magnetic carpet show it to be highly dynamic, where the time taken for all flux within the magnetic carpet to be replaced is on the order of just a few hours. The magnetic carpet is continually evolving due to the Sun's underlying convection and the interaction of small-scale magnetic features with one another. Due to this, the small-scale coronal field of the magnetic carpet is also expected to be highly dynamic and complex. Previous modelling has shown that much of the flux

Abstract:

Lorentz TEM observations of magnetic nanoparticles contain information on the magnetic and electrostatic potentials of the sample. These potentials can be extracted from the electron wave phase shift by separating electrostatic and magnetic phase shifts, followed by 3D tomographic reconstructions. In past, Vector Field Electron Tomography (VFET) was utilized to perform the reconstruction. However, VFET is based on a conventional tomography method called filtered back-projection (FBP). Consequently, the VFET approach tends to produce inconsistencies that are prominent along the edges of the sam

Abstract:

Magnetic ﬁelds are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted ﬁelds visible in solar ﬁlaments/prominences. The free magnetic energy contained in such ﬁelds is the primary source of energy for coronal mass ejections, which are important—but still poorly understood drivers of space weather in the near-Earth environment. In this thesis, a new model is developed for the evolution of the large-scale magnetic ﬁeld in the global solar corona. The model is based on observations of the radial magnetic ﬁeld

Abstract:

We have used techniques of nonlinear dynamics to compare a special model for the reversals of the Earth's magnetic field with the observational data. Although this model is rather simple, there is no essential difference to the data by means of well-known characteristics, such as correlation function and probability distribution. Applying methods of symbolic dynamics we have found that the considered model is not able to describe the dynamical properties of the observed process. These significant differences are expressed by algorithmic complexity and Renyi information.

This ability to manipulate the flow field is of technological importance in industrial processes.

This dissertation addresses the problem of elevation of the T wave of an electrocardiogram (ECG) signal in the magnetic resonance imaging (MRI). In the MRI, due to the strong static magnetic field the interaction of the blood flow with this strong magnetic field induces a voltage in the body. This voltage appears as a superimposition at the locus of the T wave of the ECG signal. This looses important information required by the doctors to interpret the ST segment of the ECG and detect diseases such as myocardial infarction.

In one dimension the development of domain walls precludes long-range order in discrete systems; this is as free energy savings due to entropy outweigh the energetic cost of a domain wall.

Abstract:

Analysis of electromagnetic stepper motor at work have been performed. Types of stepper motors and its characteristics have been described generally. The programmes of modelling have been searching using internet and analysed. The programme QuickField 5.2 Studen‘s edition is in consort to demands and requests. Using QuickField 5.2 Student‘s edition the model of electromagnetic motor have been created and experimentations have been performed. Varying displacement of motor magnetic part the distribution of magnetic flux density and magnetic field lines have been analysed. The experimentations in

Abstract:

Vortex flows in the solar atmosphere may contribute significantly to the energy flux requirements for heating the quiet Sun atmosphere. This thesis presents evidence that the expected number of vortices in the solar photosphere is significantly larger than estimated and most importantly their lifetime is, in the mean, much shorter than previously believed. This suggests that vortex flows are highly dynamic and that their formation and dissolution is highly temporally localised. The measurements and statistics that support this evidence were made possible by use of an automated vortex identific

Abstract:

This thesis reports the research work performed during the three years of my Ph.D. course at the Physics Department ''Galileo Galilei'' of the Università di Padova. Most of my research activity has been carried out at the Consorzio RFX, located inside the Consiglio Nazionale delle Ricerche (CNR) area of Padova, where operates the Reversed Field eXperiment, namely RFX-mod, the largest fusion experiment currently operating in the Reversed-Field Pinch (RFP) configuration. The RFP, together with the Tokamak and the Stellarator, is one of the main configurations used to confine a plasma in a tor

Abstract:

Gravity gradient tensor (GGT) data contains the second derivatives of the Earth’s gravitational potential in three orthogonal directions. GGT data can be measured either using land, airborne, marine or space platforms. In the last two decades, the applications of GGT data in hydrocarbon exploration, mineral exploration and structural geology have increased considerably. This work focuses on developing new interpretation techniques for GGT data as well as pseudo-gravity gradient tensor (PGGT) derived from measured magnetic field. The applications of developed methods are demonstrated on a GGT d
