Study of Steady-State Wake Characteristics of Variable Angle Wedges
… In addition, several different combinations of wedges were also examined to see if single wedge analysis could be applied to arrays of wedges. Analysis was done on combinations of wedges aligned vertically as well as combinations that were done horizontally. It was found that single wedge …

"Hammering in the wedges": The political praxis of Harriette Colenso in Zululand and Natal, 1884 to 1913
… this study refers to as her ‘hammering in the wedges.' The study shows that she had a series of small successes that in the long-term contributed in important ways to political gains by the Zulu monarchy. The study highlights the characteristic features of Colenso's political praxis, …

Behavior of Hybrid Thick- and Thin-Skinned Orogenic Wedges in the Western Interior USA and South-Central Andes
The western interiors of North and South America host two of the largest fold and thrust belts on Earth, recording upper-plate processes active during ocean-continent convergence and the construction of Cordilleran orogenic systems. These systems are at dramatically different stages in their …

Analysis and characterization of the integrated dielectric slab waveguide-wedge antenna using iterative mode-matching technique
… and exhibit very low side lobes. Longer length wedges are shown to produce higher directivity and smaller half-power beamwidths (HPBW). For TB polarization, wedges with larger values of dielectric constant yield smaller directivity and broader HPBW. In contrast, for TM polarization, wedges with …

Ultrasonic inspection methods for defect detection and process control in roll-to-roll flexible electronics manufacturing
… roll-to-roll manufacturing. A variety of custom wedges were designed and machined from multiple materials to test their suitability at launching ultrasonic Lamb waves along Polyethylene Terephthalate (PET) film. Using hydrogel wedges, the fundamental antisymmetric (Ao) Lamb wave mode was …

On Motion Mechanisms of Freight Train Suspension Systems
… system experiences impacts and friction between wedges and bolster. The impacts cause the chatter motions between wedges and bolster, and the friction will cause the stick and non-stick motions between wedges and bolster. Due to the wedge effect, the suspension system may become stuck and not …

Complex Bogie Modeling Incorporating Advanced Friction Wedge Components
… a bolster, two spring nests, and four friction wedges. The two sideframes sit on the axels. The bolster rides on springs on top of the sideframes. The friction wedges also ride on springs on top of the sideframe, and are positioned between the bolster and sideframe, acting as a damping …

Understanding the mechanism of injury associated with long bone fractures through dynamic bending impact
… 11.8% of the fractures produced were tension wedges and 14.7% were compression wedges. When applying the existing methods of inferring directionality to the fractured sample, the accuracies ranged from 5.9% to 59%, while the method developed during this study achieved an accuracy of 97.1%. …

The synthesis, structure and chemistry of some novel organometallic dendrimers
… several series of novel organometallic dendritic wedges and small dendrimers containing iron, ruthenium, cobalt and tungsten have been investigated. The compounds have been synthesised using the convergent methodology of Hawker and Fréchet. Haloalkyl complexes such as Cp*Fe(CO)₂(CH₂)₃Br and …

On the impact of arbitrary two-dimensional sections
… The linearized formulation of Wagner (1932) for wedges of small deadrise angles is adopted and extended to general body geometries with the boundary condition on the body satisfied exactly. For wedges and circular cylinders, we derive closedform solutions by using the conformal mapping …

Peak pressure under the forefoot in classical ballet
… modalities in the form of a gel sock and gel toe wedges, determining the ability to alleviate pressure under the forefoot. Fifteen female dancers aged between 18 and 25 (mean age 19 years) were examined, and local loading of the forefoot was assessed under three conditions: a) in the absence of …

Synthesis of functional polyimide and its application in nanostructured films
… has been synthesized and modified with dendrimer wedges. The effect of dendrimer wedges in formation of porous structure in bulk film was investigated. Lower density and higher extend of butanol intrusion of the modified polyimide bulk film after thermal treatment shows uniform porous structure. …

Gröbner bases in rational homotopy theory
… to compute directly the E2 term for pushouts of wedges of spheres. In particular, for a cofiber sequence A --> X --> C where A and X are wedges of spheres, we use this calculations to generalize a result of Anick by giving necessary and sufficient conditions for the map X --> C to be surjective …
