BackgroundUsing fewer distal screws in volar plate fixation of radius fractures could reduce treatment costs and complications. However, there is currently no consensus on the ideal screw configuration, likely due to experimental limitations its subject-specific nature. In this study, finite element analysis was used investigate (1) if reducing number biomechanically feasible (2) an optimal con...

This research extends on previous work which has its origin in a method, Space Syntax Analysis [2], to describe and analyse patterns of architectural space – both at the building and urban level. In the process of applying space syntax analysis [3] the space (roads, parks, etc.) in the town is partitioned into the smallest number of convex polygons to cover the whole town. Then the axial lines ...

The design and application of a patented active actuator design that combines the radial and axial actuator into one combination radial-axial actuator is presented. The theory of operation of the actuator is defined and magnetic finite element analysis modeling shown verifying operation. Its mechanical construction is then presented to show how this actuator configuration is successfully integr...

The M & S configuration ** gives equilibrium for a toroidal plasma without net current in the azimuthal direction and without rotational transform. Explicit solutions are obtained only for the restricted cases ß = 0 , and ß 1 in the surface current model, but configurations with continuous pressure profile are proved to exist. The use of the M & S configuration to confine a toroidal theta pinch...

A hybrid fuzzy sliding mode controller is applied to the control of motorised tether spin-up coupled with an axial oscillation phenomenon. A six degree of freedom dynamic model of a motorised momentum exchange tether is used as a basis for interplanetary payload exchange. The tether comprises a symmetrical double payload configuration, with an outrigger counter inertia and massive central facil...

Temporal focusing multiphoton microscopy is a technique for performing highly parallelized multiphoton microscopy while still maintaining depth discrimination. While the conventional wide-field configuration for temporal focusing suffers from sub-optimal axial resolution, line scanning temporal focusing, implemented here using a digital micromirror device (DMD), can provide substantial improvem...

This paper presents a new type of contractile polymer-based electromechanical linear actuator. The device belongs to the class of dielectric elastomer actuators, which are typically capable of undergoing large deformations induced by an applied electric field. It is based on a novel helical configuration, suitable for the generation of electrically driven axial contractions and radial expansion...

The stiffness of fracture fixation devices together with musculoskeletal loading defines the mechanical environment within a long bone fracture, and can be quantified by the interfragmentary movement. In vivo results suggested that this can have acceleratory or inhibitory influences, depending on direction and magnitude of motion, indicating that some complications in fracture treatment could b...

A mathematical programming problem is proposed for form-finding of cable domes. The optimality conditions of the problem are derived to guarantee that the optimal solution coincides with the self-equilibrium configuration of the cable dome with specified member axial forces. The number of independent axial forces is investigated under the geometrical constraints as well as equilibrium condition...

The NiN 4 –Cl SAs/N–C electrocatalyst consisting of active sites with axial Ni–Cl coordination was synthesized. Cl-coordination modulates the electronic configuration Ni–N and enhances interaction Ni–H efficiently.
