fl-. on the traditional toroidal coil windings is presented. Abstract Field-containing inductors are required in certain simulator applications e.g., elements of pulse shaping networks, terminators for transmission lines etc. Typical coils such as solenoids have a large magnetic dipole moment resulting in excessive interfering magnetic fields. An improved design based on the traditional toroida...

The Hough Transform is a well-known method for detection of parametrized objects. It is the de facto standard for detecting lines and circles in 2-dimensional data sets. For 3D it has attained little attention so far. Apart from computation costs, the main problem lies in the representation of the accumulator: Usual implementations favor geometrical objects with certain parameters due to uneven...

This paper introduces Eureka (see video), a new parallel mechanism providing five motions: three translations plus two rotations. This device is able to reach high tilting angles ( about a first given axis and a whole revolution about the following axis). This is due to actuation redundancy and to the specific traveling plate. Kinematic models are derived. Due to its particular shape the forwar...

An innovative computational tool (DAG-MCNP) has been developed for efficient and accurate 3-D nuclear analysis of geometrically complex fusion systems. Direct coupling with CAD models allows preserving the geometrical details, eliminating possible human error, and faster design iterations. DAG-MCNP has been applied to perform 3-D nuclear analysis for several fusion designs and demonstrated the ...

Patient-to-patient variations in artery geometry may determine their susceptibility to stenosis formation. These geometrical variations can be linked to variations in flow characteristics such as wall shear stress through stents, which increases the risk of restenosis. This paper considers computer models of stents in non-symmetric flows and their effects on flow characteristics at the wall. Th...

Geometrical designs of interacting nanomagnets have been studied extensively in the form two-dimensional arrays called artificial spin ice. These systems are usually designed to create geometrical frustration and interest for unusual often surprising phenomena that can emerge. Advanced lithographic element growth techniques enabled realization complex involve elements arranged three dimensions....

The paper explores an omnidirectional antenna configuration composed of a reflector fed by shaped dielectric lens associated with coaxial TEM horn. A simple formula describes the shape obtained applying Fermat’s principle to control rays’ caustic emerging from interface. Based on geometrical optics (GO) principles, synthesis technique defines radiation pattern in vertical plane. Concatenated co...

Geometrical optical projection three-dimensional profile measurement has the advantages of non-contact, non-destructive, and fast data acquisition. Its system is most promising kind macro-optical profiler. The thesis analyzes laser light source image acquisition processing, designs tomographic reconstruction display experimental imaging system, conducts theoretical analysis its theory, quality ...

The Raychaudhuri equation is derived by assuming geometric flow in space–time M of n+1 dimensions. turns into a harmonic oscillator form under suitable transformations. Thereby, relation between geometrical entropy and mean geodesic deviation established. This has connection to chaos theory where the trajectories diverge exponentially. We discuss its application cosmology black holes. Thus, we ...

in this study, geometrical, gravimetrical and frictional properties of four common varieties of iranian canola seeds (namely: slm, hyola, okapi, orient), containing the mean moisture value of 6.5% (w.b.) were investigated. geometrical and gravimetrical properties included length, diameter, geometric mean diameter, sphericity, thousand seed mass, volume, true density, bulk density and porosity. ...
