Multi-body dynamic and finite element modeling of ultra-large dump truck - haul road interactions for machine health and haul road structural integrity
… systems. Ultra-large trucks impose high dynamic loads on haul roads. The dynamic loads are exacerbated by road surface roughness and truck over-loading. The dynamic forces also subject trucks to high torsional stresses, which affect truck health. Current haul road response models are 2D …

Ousia and the Poiesis of Character Findings from an Interaction
Allowing the interaction of two dynamic forces that vie for dominance to be a form, a new character emerges. The character of the new form is present in the qualities of its making.

Heating effects on magnetorheological dampers
… and prevent civil structures against external dynamic forces such as strong wind and earthquakes. Indeed, damping devices absorb and dissipate the energy input during an earthquake, for instance and thus make structures safer and stable. Many types of devices are currently used such as viscous, …

Dynamic ergonomic analysis and simulation of fastening operation
… at awkward postures is subjected to external forces that may pose a risk of developing ergonomic injuries. For design of safe workplaces and selection of tools it is necessary to identify the probable causes of discomfort by simulating the work conditions and quantifying the risk factors. An …

Molecular Basis of Cell Adhesion Mechanics
… multiple adhesion bonds in parallel subject to dynamic forces. Correlations between the dynamic strength and measurable kinetic and thermodynamic properties of the molecular bond are predicted based on the model. The model is further extended to a sphere-on-plane geometry commonly used in …

The experience of restlessness: a study of movement in the shorter fiction of Franz Kafka
… and purposive activity and their experience of dynamic forces that escape or resist any form of containment. This conflict results in an oscillating motion that dominates the physical, mental and narrative movements shaping Kafka’s stories. Analysing the relation between early and later texts, …

Strength in Flexibility; Research into Innovative Flexible Bearing Designs for Wave Convertor Permanent Magnet Generators
… of the MMA concepts. The magnitude of the forces within the generators, during operation, lead to the creation 2-stage bearing and MMA concepts. The key reasons for them being to reducing dynamic forces within the generator and increase tolerance to design flaws and damage. Reducing the …

Epochs of Ecology: The Transition from Feudalism to Capitalism
… Marxian approach to grasp the social and natural dynamic forces involved in the transition from feudalism to capitalism in England from the 14th to the 19th century. This thesis historically examines the dissolution of the feudal mode and the rise of the capitalist mode by highlighting three …

Design and characterization of a low cost dual differential proving ring force sensor utilizing Hall-effect sensors
… the most common methods of measuring static and dynamic forces, yet they suffer from a wide array of negative attributes including: high cost due to signal amplification instrumentation, high temperature sensitivity, and only moderate dynamic range. The goal of the research herein described was …

Robotic manipulation by pushing at a single point with constant velocity : modeling and techniques
… influence the object motion through the dynamic effects of inertia and friction rendering the quasi-static assumption invalid. Numerical simulations explore the system behavior under a variety of configurations revealing the effect of the dynamic forces on the object motion and the …

An approximate method for the transient response of nonlinear systems
… of engineering structures which are subjected to dynamic forces is an area of study which has received considerable attention in recent years. In some cases, an understanding of the behavior of a structure under its expected time-varying loads is imperative so that the designed facility fulfills …

Discourse and Psyche: Three Women's Texts of Empire
… and resistance. Rather than exploring the dynamic psychic processes that give rise to colonial women's representations of the colonized, critics have largely, indeed almost exclusively, identified and categorized the ideological positions of colonial women's texts, concluding that the texts …

An instrumentation system for the measurement and display of the dynamic force distribution under the foot during locomotion
… which have been proposed for recording the dynamic forces acting on the foot are either too complex for clinical practise or there is difficulty in relating the measured force distribution to the physical surface of the foot. The system that has been developed measures the vertical …

A bioclimatic approach to integrated design : form, technology, and architectural knowledge
… which architectural elements can engage the dynamic forces of natural phenomena and integrate the spatial and temporal experience of building form with its physical environment. The framework for this exploration is a contextual mapping of dynamical systems and complexity theory to the …

Development of an apparatus to quantify the volitional muscle performance of rat plantar flexors in vivo
… at the bottom of the tube to measure the dynamic force exerted by the plantar flexors. Inside the tube, a neck ring was supported by a yoke that moved along two vertical shafts via linear bearings. A displacement transducer (LVDT) was attached to the weight pan to measure the range of …

Imaging of crust and mantle structures with teleseismic reflected waves
… suggest that petrological heterogeneities or dynamic forces must also play a role in mantle buoyancy. To improve mantle transition zone imaging, we developed an array processing technique to remove random and signal-generated noise that contaminating SS precursors. Application of our scheme to …
