Algebraic Limit Cycles in Piecewise Linear Differential Systems
(World Scientific Publ Co Pte Ltd, 2018-03-01)
This paper is devoted to study the algebraic limit cycles of planar piecewise linear differential systems. In particular, we present examples exhibiting two explicit hyperbolic algebraic limit cycles, as well as some ...

Estimating common sectoral cycles
(Elsevier Science Bv, 1995-02)
We investigate in this paper the degree of short-run and long-run comovement in U.S. sectoral output data by estimating sectoral trends and cycles. A theoretical model based on Long and Plosser (1983) is used to derive a ...
Almost partitioning 2-edge-colourings of 3-uniform hypergraphs with two monochromatic tight cycles
(Elsevier B.V., 2017)
We show that any 2-colouring of the 3-uniform complete hypergraph Kn (3) on n vertices contains two disjoint monochromatic tight cycles of distinct colours covering all but o(n) vertices of Kn (3). The same result holds ...
Almost partitioning 2-colored complete 3-uniform hypergraphs into two monochromatic tight or loose cycles
(Wiley-Liss Inc., 2019)
© 2018 Wiley Periodicals Inc. We show that for every η > 0 there exists an integer n 0 such that every 2-coloring of the 3-uniform complete hypergraph on n ≥ n 0 vertices contains two disjoint monochromatic tight cycles ...

Effect of thermal and mechanical cycles on the hardness and roughness of artificial teeth
In this study the effects of thermal and mechanical cycles on the hardness and roughness of artificial teeth were evaluated. Materials and Methods:Specimens were prepared and stored in distilled water at 37ºC for 48 hours ...
Life-cycle inventory for hydroelectric generation: a Brazilian case study
(Elsevier B.V., 2010-01-01)
Representative Life-Cycle Inventories (LCIs) are essential for Life-Cycle Assessments (LCAs) quality and readiness. Because energy is such an important element of LCAs, appropriate LCIs on energy are crucial, and due to ...
Life cycle assessment and life cycle cost of sugar plants evaporators
(ESCOLA DE MINAS, 2010)
The evaporators of sugar plants in Brazil have used carbon steel intensively because of it is, a low priced material, which possesses inferior corrosion resistance. The materials more indicated for the substitution of ...
