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 ...
Does cycling infrastructure reduce stress biomarkers in commuting cyclists? A comparison of five European cities
(Elsevier B.V., 2020-10-01)
There is substantial evidence that the environment has an important impact on the use of bicycles. Changes in the built environment, such as cycling infrastructure provision, usually aim at improving the efficiency, ...
Post-cycling Interface Strength Test of Geogrids
(2020-07-01)
Geosynthetic-reinforced soil structures are commonly used in seismic design in regions. The performance of GRES under seismic conditions can be found to range from very good to catastrophic. This paper presents the ...

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 ...
Effect of thermal and mechanical cycles on the hardness and roughness of artificial teeth
(2015)
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 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 ...
Life, Seasonal Cycles, and Population Fluctuation of Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae), in the Central Plain of La Araucanía Region, Chile
(Instituto de Investigaciones Agropecuarias, INIA, 2009)
Influence of the number of load cycles to obtain the stiffness properties of angico preto (<i>Anadenanthera macrocarpa</i>) wood specie
(2015)
The tests used to obtain the stiffness properties of wood are made with two loading cycles, as defined by the Brazilian standard ABNT NBR 7190 (Design of Timber Structures). However, the possibility of reducing the number ...
