BACKGROUND The Dynesys system provides stability for destabilized spines while preserving segmental motion. However, clinical studies have demonstrated that the Dynesys system does not prevent adjacent segment disease. Moreover, biomechanical studies have revealed that the stiffness of the Dynesys system is comparable to rigid fixation. Our previous studies showed that adjusting the cord preten...

Title of Document: HUMERAL FRACTURE FIXATION TECHNIQUES: A FEA COMPARISON OF LOCKING AND COMPRESSION TECHNIQUES WITH CADAVERIC PULLOUT COMPARISON OF CORTICAL COMPRESSION AND INTERNAL LOCKING SCREWS. Aaron Johnson, MS Mechanical Engineering, 2007 Directed By: Professor, Donald Barker, Mechanical Engineering Locking and non-locking humeral repair techniques provide different mechanical constructs...

In this study, a hybrid iteration force density method (HIFDM) was proposed to ensure both tension uniformity and accuracy of an antenna mesh reflector. Based on genetic algorithm (GA), the boundary cable reflector net optimized, which further improved precision The static model large deployable structure established using finite element (FEM), thus, iterative strategy for form-finding proposed...

mooring chains are critical components in the maritime industry used to secure ships and floating oil gas platforms such as FSOs stay their designated positions. The loads exerted on during routine operations additional offloading can cause structural fatigue. Therefore, fatigue life analysis of is essential ensure safety optimal performance. This study aims conduct by considering an important ...

conclusions this study indicates that low-load rt results in greater accumulations in vl compared to high-load rt over the course of 8 weeks of training. results after adjusting for the pre-test scores, there was a significant difference between the two intervention groups on post-intervention total vl with a very large effect size (f (1, 15) = 16.598, p = .001, ηp2 = .525). there was a signifi...

Detecting Ideas of Rationalization in Mediaeval Islamic Building Design – what is the point of this investigation? To tell it straight away: it’s about the interpretation of design under an economic perspective as analyzed in the case of the Rizk Cami in Hasankeyf. In this respect ‟rationalization” is not meant to describe the rule of ratio, proportions or other formal methods to produce design...

Considerable advances in robotic actuation technology have been made in recent years. Particularly the use of compliance has increased, both as series elastic elements as well as in parallel to the main actuation drives. This work focuses on the model formulation and control of compliant actuation structures includingmultiple branches andmultiarticulation, and significantly contributes by propo...
