To gain a better understanding of the forces working on the cervical spine, a spatial biomechanical computer model was developed. The first part of our research was concerned with the development of a kinematic model to establish the axes of rotation and the mutual position of the head and vertebrae with regard to flexion, extension, lateroflexion and torsion. The next step was the introduction...

A hybrid fuzzy sliding mode controller is applied to the control of motorised tether spin-up coupled with an axial oscillation phenomenon. A six degree of freedom dynamic model of a motorised momentum exchange tether is used as a basis for interplanetary payload exchange. The tether comprises a symmetrical double payload configuration, with an outrigger counter inertia and massive central facil...

The aim of this study was to determine the effects that soft tissue motion has on ground reaction forces, joint torques and joint reaction forces in drop landings. To this end a four body-segment wobbling mass model was developed to reproduce the vertical ground reaction force curve for the first 100 ms of landing. Particular attention was paid to the passive impact phase, while selecting most ...

Choosing a career within the military has many positive and negative factors associated with it. For instance, many recruits join as young adults when they are beginning to shape their own values, beliefs and attitudes about their self, world and others. The armed forces (AF) culture socialises these young adults, leading them to adopt military values and ideals as their own which they will pro...

The equine distal forelimb is a common location of injuries related to mechanical overload. In this study, a two-dimensional model of the musculoskeletal system of the region was developed and applied to kinematic and kinetic data from walking and trotting horses. The forces in major tendons and joint reaction forces were calculated. The components of the joint reaction forces caused by wrappin...

“We are without allies amongst the Iraqi populace, including those who have benefited from the ouster of Saddam. . . . Across Baghdad, Latifiyah, Mahmudiyah, Salman Pak, Baqubah, Balad, Taji, Baiji, Ramadi, and just about everywhere else you can name, the people absolutely hate us. . . . The Iraqi people have not bought into what the Americans are selling, and no amount of military activity is ...
