Recently, as the result of development in modern imaging, computerized three dimensional data processing and advanced engineering techniques, a prosthesis that match the skeletal anatomy can be accurately designed using computer aided design (CAD) where the physical model of prosthesis or skull replica can be produced through rapid prototyping (RP), rapid tooling (RT), and computer aided manufa...

Managing severe periacetabular bone loss during revision total hip arthroplasty (THA) is a challenging task. Multiple treatment options have been described. A custom triflanged acetabular component is a recent treatment option. The authors retrospectively reviewed 19 hips in 19 patients with massive periacetabular bone loss (Paprosky types 3A/3B and AAOS types III/IV) treated with custom trifla...

A rare case of local recurrence of a high-grade osteosarcoma of the pelvis is described, 19 years after initial presentation, highlighting the need for continued long-term follow-up of patients with osteosarcoma. We review the literature concerning osteosarcoma of the pelvis, local recurrence and treatment with custom-made hemipelvic replacements.

This paper provides a comparative case study detailing parallel experiences with both a modified commercial off-theshelf lens and a custom lens for small satellite applications. These lens designs were employed in two successive hardware generations of the ST-16 star tracker. The two designs are compared experimentally, measuring effective aperture, photometric efficiency, point-spread function...

BACKGROUND AND PURPOSE Femoral deformity associated with osteoarthritis is a challenge for both the surgeon and the implant. Many of the patients with these deformities are young. Standard implants can be difficult to fit into these femurs. We prospectively evaluated the outcome of custom uncemented femoral stems in young patients. METHODS 61 consecutive patients (72 hips) underwent surgery f...

Custom operators, working at custom precisions, are a key ingredient to fully exploit the FPGA flexibility advantage for high-performance computing. Unfortunately, such operators are costly to design, and application designers tend to rely on less efficient off-the-shelf operators. To address this issue, an open-source architecture generator framework is introduced. Its salient features are an ...

A semi-custom high-speed datapath design flow is described using commercial ASIC design CAD tools interacting with a simple hierarchical placement Matlab code. The flow leverages the vast automation and verification capabilities of ASIC design CAD tools, while providing a precision close to a fully custom-designed circuit. The methodology is applied to the design of a 4channel, 3-GHz per-channe...
