On Lugre Friction Model to Mitigate Nonideal Vibrations
(Asme-amer Soc Mechanical Eng, 2009-07-01)
In this paper, a nonideal mechanical system with the LuGre friction damping model is considered. The mechanical model of the system is an oscillator not necessarily linear connected with an unbalanced motor of excitation ...
Friction losses in valves and fittings for viscoplastic fluids
(Canadian Soc Chemical Engineering, 2005-04-01)
Data on pressure drop were obtained in stainless steel, sanitary fittings and valves during laminar and turbulent flow of aqueous suspensions of sucrose and bentonite. The rheological properties of these suspensions were ...
Entrepreneurship, financial frictions and the welfare gains of business cycles
(2018-08)
I propose a simple method to solve a heterogeneous agent model with entrepreneurship, financial frictions and aggregate uncertainty. Aggregate shocks, in this context, induce potential entrepreneurs to save in order to ...
Dynamic coordination with timing frictions: theory and applications
(2017)
We start by presenting the general model of dynamic coordination with timing frictions and some key theoretical results. We prove the model features a unique rationalizable equilibrium, present a method to solve the social ...

Caboclos, warrior women, f(r)iction Artist: carnations and pearls of soul
(Univ Estado Santa Catarina-udesc, 2015-12-01)
Taking as metaphors the actions of Caboclos de Lanca and Warrior women of the area of northeast woods of Pernambuco, the present work weaves a network of reflections on the sacred encounter between artists and audience in ...
Women’s Footwear Sole for the Elderly Produced with Sustainable Material: Friction Coefficient Analysis
(2020-01-01)
One possibility to intervene in falls due to slipping is to use shoes with soles that can resist possible slips. The objective of this research is to evaluate the friction coefficient of the female footwear for the elderly ...
Frictional properties of surface textures fabricated on hardened steel by elliptical vibration diamond cutting
(Elsevier Inc., 2019)
Surface texturing is a promising approach to tailor friction and wear between rubbing surfaces in mechanical components. In this study, surface textures with different geometries and shapes were fabricated on hardened steel ...
Debris, Roughness and Friction of Stainless Steel Archwires Following Clinical Use
(E H Angle Education Research Foundation, Inc, 2010-05-01)
Objective: To investigate the degree of debris, roughness, and friction of stainless steel orthodontic archwires before and after clinical use.Materials and Methods: For eight individuals, two sets of three brackets (n = ...
