Altered hip muscle forces during gait in people with patellofemoral osteoarthritis

Crossley, K. M.; Dorn, T. W.; Ozturk, H.; van den Noort, J.; Schache, A. G.; Pandy, M. G. (ELSEVIER, 2012-11-27)

Objectives: The study aimed to (1) assess whether higher vasti (VASTI), gluteus medius (GMED), gluteus maximus (GMAX) and gluteus minimus (GMIN) forces are associated with participant characteristics (lower age, male gender) ...

Industrial Environmental Performance Evaluation: a Markov-based model considering data uncertainty

SHOKRAVI, SAMANEH; Smith, Alan J. R.; BURVILL, COLIN (Elsevier, 2014)

Commonly, operational aspects of an industrial process are not included when evaluating the process environmental performance. These aspects are important as operational failures can intensify adverse environmental impacts ...

Effects of changing aspect ratio through a wind tunnel contraction

Callan, J.; Marusic, I. (American Institute of Aeronautics & Astronautics, 2001)

No abstract.

The feasibility of downsizing a 1.25 liter normally aspirated engine to a 0.43 liter highly turbocharged engine

Attard, William; Konidaris, Steven; Toulson, Elisa; Watson, Harry (SAE Technical Paper Series, 2007)

In this paper, performance, efficiency and emission experimental results are presented from a prototype 434 cm3, highly turbocharged (TC), two cylinder engine with brake power limited to approximately 60 kW. These results ...

Compression ratio effects on performance, efficiency, emissions and combustion in a carbureted and PFI small engine

Attard, William; Konidaris, Steven; Hamori, Ferenc; Toulson, Elisa; Watson, Harry (SAE Technical Paper Series, 2007)

This paper compares the performance, efficiency, emissions and combustion parameters of a prototype two cylinder 430 cm3 engine which has been tested in a variety of normally aspirated (NA) modes with compression ratio ...

A wall-wake model for the turbulence structure of boundary layers. Part 2. Further experimental support

Marusic, I.; Perry, A. E. (Cambridge University Press, 1995)

In Part 1 an extension of the attached eddy hypothesis was developed and applied to equilibrium pressure gradient turbulent boundary layers. In this paper the formulation is applied to data measured by the authors from ...

The effect of aspect ratio and divergence on the turbulence structure of boundary layers

Jones, M. B.; Marusic, I.; Perry, A. E. (2007)

The effect of the aspect ratio of a turbulent boundary layer on the mean flow, broadband turbulence intensities and Reynolds shear stress has been studied. The aspect ratio (AR) is defined as the boundary layer thickness ...

Surface shear stress fluctuations in the atmospheric surface layer

Monty, J. P.; Chong, M. S.; Hutchins, N.; Marusic, I. (2006)

A lightweight, high frequency response, floating element sensor was used to measure wall shear stress fluctuations in an atmospheric surface layer. The sensor uses a laser position measurement system to track the motion ...

A wall-wake model for the turbulence structure of boundary layers. Part 1. Extension of the attached eddy hypothesis

Perry, A. E.; Marusic, I. (Cambridge University Press, 1995)

The attached eddy hypothesis developed for zero pressure gradient boundary layers and for pipe flow is extended here to boundary layers with arbitary streamwise pressure gradients, both favourable and adverse. It is found ...

Wall turbulence closure based on classical similarity laws and the attached eddy hypothesis

Perry, A. E.; Marusic, I.; Li, J. D. (1994)

A new look at the closure problem of turbulent boundary layers is taken here using recently derived analytical expressions for the shear stress distributions. These expressions are based on logarithmic law of the wall and ...
