Improvement of cycles slip threshold for the TD method in the relative positioningMelhoria no limiar de detecção de perda de ciclos para o método das TD no posicionamento relativo
(2021-02-20)
Carrier phase and code observable are used in high accuracy positioning by global navigation satellite systems. However, the carrier phase measurement may suffer cycle slip during signal tracking. Cycles slip is a discontinuity ...
Risk factors for rapid cycling in bipolar disorder.
(John Wiley & Sons A/S. Published by John Wiley & Sons Ltd., 2015)
The aim of this study was to investigate the clinical factors associated with the development of rapid cycling, as well as to elucidate the role of antidepressants.
METHODS:

Partitioning two-coloured complete multipartite graphs into monochromatic paths and cycles
(Wiley-Liss Inc., 2019)
© 2018 Wiley Periodicals, Inc. We show that any complete k-partite graph G on n vertices, with k≥3, whose edges are two-coloured, can be covered with two vertex-disjoint monochromatic paths of distinct colours, given that ...
Yeast Activities Involved in Carbon and Nitrogen Cycles in Antarctica
(Springer Nature Switzerland AG, 2019)
Antarctica and sub-Antarctic regions are characterized by extreme conditions for life such as low temperatures and nutrient availability, high solar irradiation, and dryness; however, microorganisms from the three domains ...
Optimization of an irreversible Otto and Diesel cycles based on ecological function
(2018-01-01)
In this work, a mathematical model is presented for the irreversible Otto and Diesel cycles using finite time thermodynamics. The cycle is analyzed between two reservoirs with infinite thermal capacitances, where the ...
Solar Cycle and Seasonal Distribution of Geomagnetic Storms with Sudden Commencement
(Canadian Center of Science and Education, 2014-02)
In this brief paper the seasonal and solar cycle distribution of storms with sudden commencement is presented. A correlation between the number of geomagnetic storms by month and monthly sunspot numbers is observed. Also, ...
On the Limit Cycles for a Class of Continuous Piecewise Linear Differential Systems with Three Zones
(World Scientific Publ Co Pte Ltd, 2015-04-01)
Lima and Llibre [2012] have studied a class of planar continuous piecewise linear vector fields with three zones. Using the Poincare map, they proved that this class admits always a unique limit cycle, which is hyperbolic. ...
Limit Cycles Bifurcating from a Period Annulus in Continuous Piecewise Linear Differential Systems with Three Zones
(World Scientific Publ Co Pte Ltd, 2017-02-01)
We study a class of planar continuous piecewise linear vector fields with three zones. Using the Poincare map and some techniques for proving the existence of limit cycles for smooth differential systems, we prove that ...
