Learn while tracking. (c2013)

Toukhtarian, Raffi (2013-09-03)

Controlling a plant and automatically driving its output to track a user-defined reference trajectory with sufficiently small error has been an important problem in control theory and application. This problem is referred ...
Bidirectional electronic textile token grid network topology. (c2013)

Khalil, Antonio F. (2013-09-03)

Electronic Textile (e-textile) applications seem to obtain more and more importance in our daily lives; the huge amount of fabrics around us help electronic textile to mingle and integrate seamlessly with our daily life ...
Parallel multi-voltage power minimization in VLSI circuits. (c2013)

Younes, Rabih Halim (2015-02-10)

Power consumption minimization is nowadays considered a main challenge to VLSI designers, especially with the growth of the mobile computing industry. Previous studies have tried minimizing power consumption at the expense ...
Designing policies using a MIMO PID controller for correlated multiple-policy multiple-objective strategic planning. (c2014)

Khalifeh, Joe (2015-02-10)

Strategic planning (SP) is the process of aligning an organization’s activities with its own vision and mission. Several strategic planning frameworks and tools were developed such as SWOC, Porter’s five forces and PEST ...
The graphic novel's West Asian new wave. (c2014)

Sabbagh, Mona Majzoub (2015-02-26)

While the graphic novel is becoming a well-established genre in the West with its own definitions, bi-cultural authors develop a new West Asian trajectory, both in form and subject, from their own displacements as well as ...
Effects of deck transverse cracks on the temperature distribution in composite bridges. (c2014)

Masri, Omar Youssef El (2015-09-18)

Thermally induced stresses in composite steel-concrete bridges are higher than those experienced by their concrete and steel cousins due to dissimilarity in material properties. These thermal stresses are relatively high ...
A Film Thickness Correction Formula for Double- Newtonian Shear-Thinning in Rolling EHL Circular Contacts

Habchi, Wassim; Bair, S.; Qureshi, F.; Covitch, M. (2015-09-21)

Lubricants which contain a polymeric thickener will often display a second Newtonian plateau in measured flow curves. Like other manifestations of shear-dependent viscosity, this shear response will lead to an inaccurate ...
A numerical investigation of local effects on the global behavior of TEHD highly loaded circular contacts

Habchi, Wassim; Vergne, P.; Bair, S.; Fillot, N.; Morales-Espejel, G. E. (2015-09-21)

This paper presents a numerical investigation of the local behavior of highly loaded thermal elastohydrodynamic contacts. The study is a continuation to a previous work of the authors where it was found that neglecting the ...
A numerical model for the solution of thermal elastohydrodynamic lubrication in coated circular contacts

Habchi, Wassim (2015-09-21)

This paper presents a finite element model for the solution of thermal elastohydrodynamic lubrication in coated circular contacts. The model is based on a full-system finite element resolution of the elastohydrodynamic and ...
Full Film, Boundary Lubrication and Tribochemistry in Steel Circular Contacts Lubricated with Glycerol

Habchi, W.; Matta, C.; Joly-Pottuz, L.; De Barros, M.I.; Martin, J.M.; Vergne, P. (2015-09-21)

In this article, the lubricating properties of pure glycerol are investigated under both mild and severe EHL regimes. Amazingly low friction coefficients (about 0.01) are reported by experiments in thick film regimes ...
Influence of Pressure and Temperature Dependence of Thermal Properties of a Lubricant on the Behavior of Circular TEHD Contacts

Habchi, Wassim; Vergne, P.; Bair, S.; Andersson, O.; Eyheramendy, D.; Morales-Espejel, G. E. (2015-09-21)

The aim of this paper is to study the effects of pressure and temperature dependence of a conventional lubricant's thermal properties on the behaviour of heavily loaded thermal elastohydrodynamic lubrication (TEHL) contacts. ...
Stabilized Fully-Coupled Finite Elements for Elastohydrodynamic Lubrication Problems

Habchi, Wassim; Eyheramendy, D.; Vergne, P.; Morales-Espejel, G. (2015-09-21)

This work presents a model for elastohydrodynamic (EHD) lubrication problems. A finite element full-system approach is employed. The hydrodynamic and elastic problems are solved simultaneously which leads to fast convergence ...
On friction regimes in quantitative elastohydrodynamics

Habchi, W.; Bair, S.; Vergne, P. (2015-09-21)

This paper identifies the different friction regimes encountered in elastohydrodynamic lubricated point contacts using a quantitative, physics-based approach. The idea is to link different traction regimes to dimensionless ...
Quantitative Compressibility Effects in Thermal Elastohydrodynamic Circular Contacts

Habchi, W.; Bair, S. (2015-09-21)

This paper investigates the effects of lubricant compressibility on the film-forming performance of thermal elastohydrodynamic lubricated (EHL) circular contacts. Numerical film thickness predictions using the classical ...

Habchi, Wassim; Vergne, P.; Eyheramendy, D.; Morales-Espejel, G. E. (2015-09-21)

This study proposes a numerical investigation of the potential use of machinery working fluids as lubricants in contacts operating under an elastohydrodynamic regime. These fluids are usually of very low viscosity and ...
Fast and reduced full-system finite element solution of elastohydrodynamic lubrication problems

Habchi, W.; Issa, J. (2015-09-21)

This paper presents a reduced full-system finite element solution of elastohydrodynamic lubrication (EHL) problems. It aims to demonstrate the feasibility of this approach by applying it to the simple isothermal Newtonian ...
Thermal Elastohydrodynamic Lubrication of Point Contacts Using a Newtonian/Generalized Newtonian Lubricant

Habchi, W.; Eyheramendy, D.; Bair, S.; Vergne, P.; Morales-Espejel, G. (2015-09-28)

The classical ElastoHydroDynamic (EHD) theory assumes a Newtonian lubricant and an isothermal operating regime. In reality, lubricating oils do not behave as perfect Newtonian fluids. Moreover, in most operating conditions ...
