Analysing the new Saturnian rings, R/2004 S1 and R/2004 S2
(Springer, 2005-12-01)
The Cassini-Huygens arrival into the Saturnian system brought a large amount of data about the satellites and rings. Two diffuse rings were found in the region between the A ring and Prometheus. R/2004 S1 is coorbital to ...
Compact triplexer with open ring resonators as microstrip trisection bandpass filters for asymmetric response
(Scopus, 2013)
Open loop ring resonators are used as the basic block of a compact planar triplexer, they are used in cascaded trisection (CT) filters, in order to reduce the circuit size. The CT filter has a cross coupling that produces ...
Construction and decoding of BCH codes over chain of commutative rings
(2012)
In this paper, we present a new construction and decoding of BCH codes over certain rings. Thus, for a nonnegative integer t, let A0 ⊂ A1 ⊂···⊂ At−1 ⊂ At be a chain of unitary commutative rings, where each Ai is constructed ...
Central quasipolar rings
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Matemáticas - Sociedad Colombiana de Matemáticas, 2015-07-01)
In this paper, we introduce a kind of quasipolarity notion for rings, namely, an element a of a ring R is called central quasipolar if there exists p2 = p ∈ R such that a + p is central in R, and the ring R is called central ...
Elimination of quantifiers of a theory of real closed rings.
(2022-10-09)
Let T* be the theory of lattice-ordered subrings, without minimal (non zero) idempontents, convex in von Neumann regular real closed rings that are divisible-proyectable and sc-regular. In this paper, a local divisibility ...
Moonlets wandering on a leash-ring
(Blackwell Publishing, 2007-09-01)
Since the Voyager flybys, embedded moonlets have been proposed to explain some of the surprising structures observed in Saturn's narrow F ring. Experiments conducted with the Cassini spacecraft support this suggestion. ...

Passive scalar transport mediated by laminar vortex rings
(Institute of Physics Publishing, 2017)
Numerical simulations were used to study the dynamics of a passive conservedscalar quantity entrained by a self-propelling viscous vortex ring. The trans-port and mixing process of the passive scalar variable were studied ...
Evaluating the annual nature of juvenile rings in Bolivian tropical rainforest trees
(SPRINGER, 2011)
Knowledge on juvenile tree growth is crucial to understand how trees reach the canopy in tropical forests. However, long-term data on juvenile tree growth are usually unavailable. Annual tree rings provide growth information ...
