Fatigue Damage and Small Crack Growth During Biaxial Loading
… nature of fatigue damage under biaxial loading has been investigated. Experiments were performed on thin-wall tubular specimens of 1045 steel in tension, torsion, and combined tension-torsion loading. Two equivalent strain amplitudes, one in the high cycle fatigue (HCF) region and one in …

Cross-sectional Morphology and Mechanical Loading in Plio-Pleistocene Hominins: Implications for Locomotion and Taxonomy
… cross-sectional properties and mechanical loading patterns in the proximal and midshaft femur of Paranthropus, fossil Homo sp. and H. erectus. Modern human and Pan models are used for comparative purposes. Cross-sectional properties in the proximal and midshaft femur of fossil hominins are …

Segmental Movement Compensations in Patients with Transtibial Amputation Identified Using Angular Momentum Separation
… and result in increased and asymmetric joint loading patterns. As a result, this population is at an increased risk of overuse injuries, such as low back pain (LBP). Clinical gait analysis is used to guide diagnostics in movement retraining following amputation, and is performed using …

A Technique For Estimating System-Wide Phasors In Real Time
… load flow was computed for various possible loading situations. Various loading patterns were created around a base summer time load flow case. Using the results from these computations, an empirical relationship was developed between phasors from a fixed set of locations and the unknown …

A simulation study of tooling effects in automated manufacturing.
… identical, nonidentical and hybrid, and two part loading patterns; batch and random loading. In addition, a new tool refilling concept, tool replenishing, is also examined. The replenishing concept consists of two policies; preventive and failure replenishing. The effects of shared and dedicated …

Modelling the impact of total stress changes on groundwater flow
… to total stress changes caused by tailings pile loading at the ground surface to be modelled. The modified code was verified before applying to present study.Long-term pore pressure generation and dissipation due to pile construction was investigated for eleven hydrostratigraphic scenarios …

The Greedy Exhaustive Dual Binary Swap methodology for fuel loading optimization in PWR reactors using the poropy reactor optimization Tool
… for the optimization of nuclear reactor core loading patterns. The goal of this optimization scheme is to emulate the approach taken by an engineer when manually optimizing a reactor core loading pattern. This is to determine if this approach is able to locate high quality patterns that, due …

Quantifcation of Physical Loading, Energy Intake and Expenditure In English Premier League Soccer Players
… distance and duration), seasonal high-intensity loading patterns are dependent on players’ match starting status thereby having potential implications for training programme design and prescription of player-specific nutritional guidelines. Additionally, daily energy expenditures (EE) and energy …

Biomechanical Comparison of Lumbar Disc Replacements
… could be distinguished in both motion and loading patterns. It was also hypothesized that either disc replacements offered preservation of harvested motion at all motion levels whereas the pedicle screw fixation would not. Using a previously established non-destructive testing protocol, …

Assessing Symmetry in Landing Mechanics During Single-Leg and Bilateral Tasks in Healthy Recreational Athletes
… exhibit side-to-side asymmetries in movement and loading patterns after surgery, some of which are predictive of a secondary ACL injury. These asymmetries have not been fully assessed in healthy athletes. PURPOSE: To quantify side-to-side symmetry in secondary injury predictors in healthy athletes …

Drought in the Colorado River Basin: Spatiotemporal Analysis using an Edge Detection Filter
… outputs to determine whether there were specific patterns within the data. This data analysis identified repeating spatial patterns between each of the identified drought periods during drought onset, with the first principal component of the edge detection accounting for 60% of the variance in …

Surrogate Model Optimisation for PWR Fuel Management
… factors and changing goals mean that fuel loading pattern design problems are multiobjective and, by design, have many input variables. This causes a combinatorial explosion, known as the ‘curse of dimensionality’, which makes these complex problems difficult to investigate. In this thesis, …

Finite Element Analysis of the Effect of Low-Speed Rear End Collisions on the Medial Meniscus
… may produce a combination of compressive loading and torque about the knee that will injure the medial meniscus during the initial impact and the rebound phase. The purpose of this study is to determine if it is possible for rear end low-speed collisions to tear the medial meniscus when …

Exploring the Effect of Ankle Braces on Foot Posture
… that can affect kinematics, plantar loading, and injury risk. Arch height is one common aspect of foot posture, and it is estimated that about 60% of the population has normal arches while 40% of the population is either pes planus or pes cavus. It is important to be able to …

Development of a core design optimization tool and analysis in support of the planned LEU conversion of the MIT Research Reactor (MITR-II)
… applies the correlations to identify an optimal loading pattern, defined as the core which has the lowest maximum radial peaking factor in the set of valid solutions with the minimum number of fuel shuffling actions. The correlations that are utilized by the optimization tool were developed using …

Assessing environmental equivalents for water quality trading
… were also applied on subbasin level. The variant loading patterns and time distributions of each subbasin showed strong site-specific phenomena. The ANOVA of in-field nutrient load showed significant differences among the design criteria of scenarios. The results also showed a significant delivery …

An Instrumented Spatial Linkage to Measure In-Vivo Kinematics and Motion Reproduction with a Robotic Test System
… beginning at hoof strike. Results showed similar loading patterns between animals but with some quantitative differences. With respect to the gait cycle beginning at hoof strike, the PCL reached a peak load just after hoof strike (5%) followed by rapid unloading. The ACL was loaded immediately …
