Biomechanical characteristics of multidirectional single-leg landing
… the biomechanics of the lower extremities during multidirectional SLL. The results indicate that only SLL in a forward direction is tested in the majority of the literature using three-dimensional (3D) motion analysis, indicating the importance of examining other directions that seen in sports or …

Hydrodynamic modeling of towed buoyant submarine antenna's in multidirectional seas
A finite difference computer model is developed to simulate the exposure statistics of a radio frequency buoyant antenna as it is towed in a three-dimensional random seaway. The model allows the user to prescribe antenna properties (length, diameter, density, etc.), sea conditions (significant wave …

Multidirectional relationships between chronic pain, cannabis use, sleep quality, and anxiety
Chronic pain is prevelant in approximately 15 to 40% of the pediatric population and impacts an individual’s daily functioning ability, as well as their social, personal, and professional lives. This study examines the relationships between chronic pain, cannabis use, sleep quality, and anxiety. A …

Extraction methods for multidirectional driving point accelerance and transfer point accelerance matrices
<p>To experimentally determine the multidirectional driving point and transfer accelerance matrices is a difficult task that has remained unsolved for 30 years. These matrices relate both linear and rotational degrees of freedom in three dimensions. The direct measurement of dynamic moments and …

Evaluation of cyclic behavior of dense sands under multidirectional loading using centrifuge tests
… loading. However, since seismic events are multidirectional in nature, design based on unidirectional studies may lead to underestimation of vertical strains, and nontrivial settlements that can impact structures. While correlations to estimate vertical strains from drained and undrained …

Effects of micro- and nano-structure on the deformation response of a Ag60Cu40 lamellar and rod-in-matrix eutectic alloy
… material system can be produced as either a multidirectional lamellar or unidirectional reinforcement-in-matrix micro-structure. Specimens of each micro-structure type were studied under quasi-static and dynamic loading conditions. The first part of this work focuses on the study of the …

Can information about Preston revealed by an artist employing a dialectic methodology of interaction and mapping, while working collaboratively with a community undergoing regeneration, be made useful to a wider audience in that city?
… environment. This study aims to investigate a multidirectional dialogic approach to the practice of contextual art. I have used mapping techniques for documenting direct experience of particular areas of Preston at different times of the day. I initiated face to face interaction with …

Micromechanics analysis of space simulated thermal deformations and stresses in continuous fiber reinforced composites
… analysis, was used to determine the stresses in multidirectional laminates. Thermally-induced damage initiation predictions were also made. The type of analysis (i.e. CC or FE) was shown to significantly affect the distributions and magnitudes of the predicted stresses. Thermally-induced matrix …

Effect of fatigue on hamstring strain injury risk in soccer
… experimental chapters that examine the effect of multidirectional soccer-specific fatigue on the primary aetiological risk factors and mechanism of injury. This was then used to create and evaluate an injury prevention programme aimed at reducing the risk of hamstring strains in soccer.

Calculation of electrical conductivity and electrothermal analysis of multilayered carbon reinforced composites: application to damage detection
… of temperature. All cases involved the study of multidirectional and unidirectional carbon fiber materials without the presence of matrix (porous form – CF preform) as well as in the presence of polymeric matrix (CFRP). The validation of the equivalent tensor was achieved through three different …
