The interpenetration and interaction of supersonic, magnetized tungsten plasma flows has been directly observed via spatially and temporally resolved measurements of the Thomson scattering ion feature. A novel scattering geometry allows independent measurements of the axial and radial velocity components of the ions. The plasma flows are produced via the pulsed power driven ablation of fine tun...
The Delannoy numbers were introduced and studied by Henri-Auguste Delannoy (1833–1915). He investigated the possible moves on a chessboard: the numbers under consideration appear when one studies “la marche de la Reine,” i.e., how the queen moves (the binomial coefficients appear similarly for the moves of the rook). The asymptotic behavior of the array of Delannoy numbers is studied. The regul...
Microfluidic devices on CD have benefited from the advantages of centrifugal pumping. To date, only channels in the radial direction have been sed in these devices. In this work, we have designed numerous spiral channels on CD. Through a two-step assembly process, these spiral channels ntersect with pre-immobilized radial DNA probe line to form an array of DNA that covers the whole CD surface. ...
As a key component in microwave applications such as antenna feeding network, power distribution network, and array systems requiring beam forming network(BFN) in satellite communication, the power divider/combiner is widely designed and implemented by using various analysis methods[1,2] and various integration method[6-8]. In array systems employing microstrip feeding network, the beam forming...
Purpose – Force output is extremely important for electromagnetic linear machines. The purpose of this study is to explore new permanent magnet (PM) array and winding patterns to increase the magnetic flux density and thus to improve the force output of electromagnetic tubular linear machines. Design/methodology/approach – Based on investigations on various PM patterns, a novel dual Halbach PM ...
This paper presents a fast and novel algorithm for both radial and bilateral symmetry detection based on inverted gradient hash maps (IGHMs). A hash map is an associative array that stores image gradient magnitudes and orientations in the form of an inverted index. This mapping of image gradients to their locations permits points of interest to be located very rapidly without needing to search ...
