Biomechanical properties of the costovertebral joint
Medical Engineering & Physics, 2010Proper modeling of the human trunk requires a quantitative assessment of the stiffness of the costovertebral joints. Twelve samples (adjacent thoracic vertebrae and one rib segment) were harvested from three subjects. The ribs were loaded in the cranial-caudal direction, the ventral-dorsal direction and in torsion around the cervical rib axis.

Frictional Properties of Artificial Hip Joints
Engineering in Medicine, 1988A 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 ...

Properties of joint gaussian statistics
Radio Science, 1978In 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.

Joint Synchronization Using Cyclic Property
2009 IEEE International Conference on Communications, 2009It 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

Properties of wet welded joints
Welding International, 1993Summary 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.

Properties of Wet Welded Joints
Offshore Technology Conference, 1989ABSTRACT 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 Large Multispot Ultrasonically Welded Joints
Journal of Aircraft, 1980Using ultrasonic spotwelds, two series of overlap joints were prepared with aluminum alloys and tested in tension. In the first series between 4x12x0.063 in.-thick panels, it is shown that on a one-for-one basis ultrasonic welds produce joints superior to those made with Vi-in. steel fasteners.

The Spectral Properties of Temporomandibular Joint Sounds
Journal of Dental Research, 1987Spectral 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.

Mechanical properties of rock joints
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1985Abstract 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.
