Bifurcations and chaos in discrete-time gonorrhea model
(2019)A deterministic epidemic model for the spread of gonorrhea is investigated in discrete-time by taking into account the interval between successive clinical cases. It is shown that the discrete-time dynamical system exhibits ... -
Buckling of thin-walled long steel cylinders under bending
(2010)The present paper investigates structural response and buckling of long unstiffened thin-walled cylindrical steel shells, subjected to bending moments, with particular emphasis on their stability design. The cylinder ... -
Compression-only behavior: Effect of prestress and shell rheology on bifurcation diagrams and parametric stability of coated microbubbles in an unbounded flow
(2022)Lipid-shelled microbubbles exhibit a strain-softening behavior and thus are characterized by preferential excursion from equilibrium during expansion at insonation. However, experimental studies have reported a counterintuitive ... -
Nonlinear supply and demand model with two interrelated markets
(2011)Our target in this paper is to observe how the presence of nonlinear terms in the supply and demand model changes the price behavior of the system. The dynamical analysis refers, mainly, to discrete dynamical systems. We ... -
Numerical implementation of J 2 non-associative flow plasticity models
(2009)The present paper describes a J2 non-associative plasticity model, which takes into account the "corner-like" effects at the loading point on the yield surface, and is suitable for shell buckling calculations. The plastic ... -
Remodeling effects of carotid artery stenting versus endarterectomy with patch angioplasty in terms of morphology and hemodynamics
(2022)Background: Carotid endarterectomy (CEA) remains the first-line treatment option of symptomatic and asymptomatic carotid stenosis, while stenting (CAS) is reserved for selected patients at high surgical risk. Here, we ... -
Wrinkling of lined pipes under bending
(2012)The present study is motivated by the use of lined pipes in energy pipeline applications (oil, gas, etc.) where a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The paper focuses on ... -
Wrinkling of lined steel pipes under bending
(2013)Lined pipes are used in energy pipeline applications (oil, gas, etc.); a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The paper focuses on wrinkling of lined pipes (sometimes also ...
