Introduction & Objective: The management of mutilated primary incisors in early childhood caries is a clinical challenge. This study's purpose was to compare the resistance strength of 3 different types of posts in restoring broken primary incisors: (1) composite posts, (2) ortho-dontic wire posts and (3) quartz fiber posts. Materials & Methods: This semi experimental in vitro study was perfo...
Long, straight mesoscale silver wires have been fabricated from AgNO3 electrolyte via electrodeposition without the help of templates, additives, and surfactants. Although the wire growth speed is very fast due to growth under non-equilibrium conditions, the wire morphology is regular and uniform in diameter. Structural studies reveal that the wires are single-crystalline, with the [112] direct...
The solution of computational electromagnetic simulations is integral to the design process. As higher performance computers become more available, the application of optimisation techniques to reduce design times becomes more feasible. This paper presents the application of Parallel BFGS and Adaptive Simulated Annealing in minimising the transmission through a ceramic bead suppressor on a stra...
We report a very low-loss hybrid silicon waveguide circuit consisting of straight rib sections with a propagation loss of 0.272±0.012 dB/cm and compact photonic wire bends of 5μm radius with a loss of 0.0273±0.0004 dB/90 o bend.
This study aims at revising the biomechanical principles of the segmented archwire technique as well as describing the clinical conditions in which the rational use of scientific biomechanics is essential to optimize orthodontic treatment and reduce the side effects produced by the straight wire technique.
We study the problem of arranging circuit components on a straight line so as to minimize the total wire length needed to realize the inter component nets. Branch-and-bound and dynamic programming algorithms that find optimal solutions are presented. In addition, heuristic approaches including some that employ the Monte Carlo method are developed and an experimental evaluation provided.
As a result of a revision of the JIS system, the application of the hot wire method for determining thermal conductivity has been expanded from heat-insulating bricks to refractories with higher heat conductivity. In this regard, focusing on magnesia bricks, which are used in the safety lining of converters and a wide variety of other applications, the authors studied the possibility of applyin...
