A method for optimally synthesizing multicomponent structural assemblies of an aluminum space frame (ASF) vehicle body is presented, which simultaneously considers structural stiffness, manufacturing and assembly costs and dimensional integrity under a unified framework based on joint libraries. The optimization problem is posed as a simultaneous determination of the location and feasible types...

Traditional methods of correcting malunited distal humeral fractures in children involve complex wedge osteotomies held with pins or internal fixation devices. These require a large exposure and challenging fixation. We elected to perform simple transverse osteotomies, without wedges, using a lateral incision. These were maintained by the small AO external fixator. Between 1987 and 2004, five c...

Abstract Parametric interpolatory curves play a vital part in geometric modeling. Cubic Catmull–Rom spline is well-known tool for constructing parametric curves, but it cannot be modified once its control points are fixed. We propose novel quartic with free parameters to tackle this issue. The owns shape adjustability based on inheriting the features of cubic spline. Some modeling examples show...

Photonic crystal has become a powerful technique for regulating electromagnetic waves due to its excellent features, such as structure designability and dynamic adjustability; in addition, it great application value. In this paper, we visualize colors on the Ostwald color model analyze differences of each group patches via minimum difference model. The manipulation law particle size, temperatur...

Filterbanks for digital hearing aids must use significantly different criteria than those designed for coding applications. For digital hearing aids, the filterbank channel gains must be adjustable over a large dynamic range to compensate for the hearing loss. This adjustability violates the alias cancellation properties of critically sampled filterbanks designed for coding. This paper describe...
