The fields of rapidly moving sources are studied within nonlinear electrodynamics by boosting the fields of sources at rest. As a consequence of the ultrarelativistic limit the δ-like electromagnetic shock waves are found. The character of the field within ...
The invention concerns a method of and an apparatus for the measurement of the Amplitude Point Spread Function (APSF), of an Optical Imaging System (OIS), wherein the APSF is defined as the complex field distribution of the beam delivered by the OIS and or ...
This paper reports the continuation of the authors' work in the field of linear and rotary submicrometric positioning using electrostatic glass motors. Electrostatic glass motors, a recent development where a glass rotor, once polarized using a static elec ...
We consider the rate-distortion problem for recording a Gaussian acoustic field with an array of sensors equipped with microphones. Our analysis is based on the field's spatiotemporal correlation structure, which is induced by the physics of sound propagat ...
Digital color, by its ambiguous nature, which always oscillates between a writing and a sensation, is always shifting, elusive, intangible, and yet, well presents, through the increasing use of computers in every field. Since it seems impossible to solve n ...
This article raises various issues in the design of an efficient BCI system in multimedia applications. The main focus is on one specific modality, namely an electroencephalography (EEG)-based BCI. In doing so, we provide an overview of the most recent pro ...
This review sums up the activity in the field of in situ product removal in whole cell bioprocesses over the last 20 yr. It gives a complete summary of ISPR operations with microbial cells and cites a series of interesting ISPR applications in plant and an ...
Standardization can be performed only in a field in which the knowledge of the physical phenomena and of the behavior of the given installation is sufficiently known. The role of the universities is to perform research in order to clarify such these points ...
We have designed and realized a new integrated Hall structure that converts the magnetic field vector in the chip plane, into an ac signal, whose amplitude and phase correspond to the magnitude and direction of the field, respectively. It is the first Hall ...
We present an application of the conformal mapping (CM) method to determine the magnetic field and force in an electromechanical actuator. First, we show how to find, using a special type of CM known as the Schwarz-Christoffel mapping, the magnetic field i ...
