The Spectral Properties of Temporomandibular Joint Sounds

Journal of Dental Research, 1987
Spectral analyses were performed on sounds recorded from TMJ's that had previously been classified into different intracapsular categories, in an attempt to determine whether the inherent properties of these sounds were unique for each different disorder.

Frictional Properties of Artificial Hip Joints

Engineering in Medicine, 1988
A new generation of hip replacements has been designed incorporating compliant layers to promote fluid film lubrication when the joints are implanted in patients. Tests in the Durham hip function simulator show that the friction in these joints is up to an order of magnitude lower than in currently used prostheses, and because this is due to complete ...

Joint Synchronization Using Cyclic Property

2009 IEEE International Conference on Communications, 2009
It is well known that the cyclic property of transmitted signal can be used to achieve joint frame and carrier frequency synchronization, while the uncompensated sampling frequency offset (SFO) would still be a problem. Based on the observation that the impact of SFO on the received cyclic block and its replica is equivalent to a relative time shift, a

Implications of Joint Properties on the Strength of a Jointed Rock Mass

Advances in Unsaturated Soil, Geo-Hazard, and Geo-Environmental Engineering, 2011
In order to minimize the environmental and physical hazards of rock slope failures in deep open cut mines, evaluation of rock mass strength with a reasonable degree of accuracy is required. The task is made much more difficult due to the presence of discontinuities or joints, as the strength of a rock mass depends on both the strength of intact rock ...

Dynamic Shear Properties of the Temporomandibular Joint Disc

Journal of Dental Research, 2003
Shear stress might be an important factor associated with fatigue failure and damage of the temporomandibular joint disc. Little information, however, is available on the dynamic behavior of the disc in shear. Since the disc is an anisotropic and viscoelastic structure, in the present study the dependency of the dynamic shear behavior on the direction ...

Dynamic Properties of the Human Temporomandibular Joint Disc

Journal of Dental Research, 2001
The cartilaginous intra-articular disc of the human temporomandibular joint shows clear anteroposterior variations in its morphology. However, anteroposterior variations in its tissue behavior have not been investigated thoroughly. To test the hypothesis that the mechanical properties of fresh human temporomandibular joint discs vary in anteroposterior

Properties of joint gaussian statistics

Radio Science, 1978
In this paper joint‐ or complex‐gaussian statistics are assumed to apply to the in‐phase and quadrature components of an electromagnetic wave which has propagated through a turbulent medium, and the consequences of this assumption are compared to tropospheric, ionospheric, and laboratory propagation experiments.

Properties of Wet Welded Joints

Offshore Technology Conference, 1989
ABSTRACT The work presently reported is a part of a joint Rand D program between GKSS Research Centre and Comex Services to develop a wet welding procedure for structural application. The main objective of the report is the presentation of so far evaluated results achieved in a wet welding test program down to a ...

Properties of wet welded joints

Welding International, 1993
Summary The increasing interest taken by the international diving industry in wet welding plays an important part in determining research activities to improve the process and consumables for offshore applications, particularly for higher strength steels at greater water depths.

Mechanical properties of rock joints

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1985
Abstract Sliding on rock joints occurs in situ under various boundary conditions. A servo-controlled direct shear testing machine was constructed to simulate these boundary conditions in the laboratory. Thirty-one sandstone samples were tested with two varying loading paths: (a) constancy of the normal force and (b) restriction of the dilation.
