Due to current limitations in in-vitro biomechanical testing, there is no consensus for the location of the inherent center of rotation (CoR) of the spine. The effects of placement of fixed CoRs of the cervical spine on segmental mechanics were investigated. A custom-designed spine robot able ...

When the J2 perturbation is explained in Chapter 3, the moments of inertia are introduced but not defined. In Section 5.3, a formal definition of the moments of inertia is explained in terms of the angular momentum of a body. The moments of inertia express the rotation of a body about its...

Clamping at the end of the specimen prohibits localized rotation and produces a nonuniform strain field. A uniform strain field can be developed at the center of the specimen provided L/w is sufficiently large [32]. The specimen length is considered to be the region between end tabs. The ...
elegans such as gait synchronization [16], swimming against the flow (rheotaxis) [17, 18], and swimming along surfaces (bordertaxis) [18] can be explained by simple mechanics. Thus, we first examine the obvious potential cause of gravitaxis: are the animals top heavy and if so, does ...

A method for monitoring the misalignment of the magnetic axis in solenoids is proposed. This method requires only a few measurements of the magnetic field at fixed positions inside the magnet aperture, and thus overcomes the main drawback of sturdy movin
As already explained, the symmetry of a space group can be derived from that of a point group by placing the latter at the points of the various lattices appropriate to the crystal system, and by using glide planes and screw axes as well as reflection planes and rotation axes. Thus the ...
Off-axis case: coordinate system rotation For the off-axis case with the coordinate system orientation shown in Fig. 2b, the global acceleration and strain fields can be rotated into material coordinates using the standard rotation matrices, given here with the abbreviations s = sine and...
