Optmization of coils for field map synthesis
International Journal of Applied Electromagnetics and Mechanics, 2013The paper proposes an optimization procedure suited to design the shape and the current feed of active coils. A suitable spline-based basis is used for the coil geometry modeling, based on a rather limited number of optimization parameters. In order to simplify the constraints treatment, a set of knot points are introduced, linked with the design ...

A light field parameterized on the surface offers a natural and intuitive description of the view-dependent appearance of scenes with complex reflectance properties. To enable the use of surface light fields in real-time rendering we develop a compact representation suitable for an accelerated graphics pipeline.

Journal of the ASB Society, 2020
This work focuses on creating maps of the geomagnetic field and areas of increased cosmic radiation surrounding the Earth. Data were measured by Proba-V satellite at Low-Earth orbit 820 kilometres above the Earth during 2015. The actual measured data were compared with the calculated magnetic values.

Flow field mapping in the anesthetized rat
Microsurgery, 1990AbstractThis study measured the hemodynamics of peripheral arterial sites in the rat, using 20 MHz pulsed ultrasonic Doppler velocimeter (PUDVM) methods. The lower extremities of 14 male Sprague‐Dawley rats were studied. The targeted sites included the abdominal aorta, external iliac, proximal femoral, mid‐femoral, and saphenous arteries.

Optical force field mapping in microdevices
Lab Chip, 2006We present a method for characterizing microscopic optical force fields. Two dimensional vector force maps are generated by measuring the optical force applied to a probe particle for a grid of particle positions. The method is used to map out the force field created by the beam from a lensed fiber inside a liquid filled microdevice. We find transverse

Magnetic field mapping in NMR imaging
Magnetic Resonance Imaging, 1987The Hahn spin preparation sequence provides a practical means for rapid and sensitive mapping of magnetic field inhomogeneity in NMR imaging applications. Choice of the rf pulse delay times tau 1 and tau 2 as well as conditions and limitations on the proposed use of this sequence for chemical shift imaging are discussed.

Reconnaissance surveys are usually carried out to establish the main topographical, geological and engineering criteria that will influence the selection and design of a new alignment (e.g. Brunsden et al. 1975) or the key issues that need to be addressed in the case of a road improvement project (environmental and social impact reviews also form ...

Geomorphological Field Mapping
2011Abstract This chapter discusses the principles and applications of geomorphological field mapping, using areas of upland terrain for example, where the presence of well-defined landforms either demonstrates ongoing geomorphic activity associated with specific process–response systems or relates to the former operation of cold climate processes ...

Magnetic Field Mapping by Selective Equipotential Excitation
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006A new magnetic field mapping method in MRI is presented. This technique is ideal for severe inhomogeneities where plane warp cannot be ignored. The present study employs a ferromagnetic ball to create a perturbation within the imaged volume. The magnetic moment and position of the device are acquired experimentally with a new technique that excites ...
