Finite fields

In this study, it is split into two main steps. First, an analytical design is proposed to define the desired parameters with affects of different flux air gaps. Then, a finite element approach is introduced to simulate magnetic field quantities (such as inductance, fringing flux, magnetic flux density, electromagnetic force, current, voltage) of the SRs.

This book is intended as a guide for security professionals, developers, and those interested in learning how elliptic curve cryptography can be deployed to secure applications. The presentation is targeted to a diverse audience, and generally assumes no more than an undergraduate degree in computer science, engineering, or mathematics. The book was not written for theoreticians as is evident from the lack of proofs for mathematical statements.

Ebook "Room acoustics (Sixth edition)" presents several additional new sections, for instance on the reflection of a spherical wave from a wall, on finite element methods for sound field calculation and on virtual reality, as well as giving an overhaul of the standard material. Particular emphasis is given to the properties and calculation of reverberation, the most obvious acoustical feature of a room.

In this paper, the corner chamfer of SR core is proposed to investigate the distribution of magnetic fields along the core block and EMF acting on the core block, as well. This development is performed with two steps: an analytical model is first presented to define main parameters of SR, then a finite element method is applied to calculate and simulate the electromagnetic parameters such as magnetic fields and electromagnetic forces of the SR.

We explored a new helical spring magnet (HSM) concept using micromagnetic simulation along with analytical modeling. The present HSMs can be made of a single magnetic material or micro/nano-scale magnetic particles in a polymer matrix, which provides for active control over the motion of the HSMs by additional forces generated by the magnetic interactions inside the HSMs.

In this paper, vibration of Timoshenko microbeams with an axial force in microelectromechanical systems (MEMS) is studied for the first time by using a nonlinear finite element procedure. Based on the von Karm´ an geometric nonlinearity and the modified couple stress theory (MCST), a beam element is formulated by employing hierarchical functions to interpolate the displacement field.
