A novel concurrent core test approach is proposed to reduce the test cost of SOC. Prior to test, the test sets corresponding to cores under test (CUT) are merged by using the proposed merging algorithm to obtain a minimum merged test set. During test, the proposed scan tree architecture is employed to support the concurrent core test using the merged test set. The approach achieves concurrent c...

Avascular necrosis (AVN) of the hips is associated with significant disability, and the majority of established cases require major surgery. In a retrospective analysis of 185 patients with systemic lupus erythematosus (SLE) 13 (7%) were found to have AVN. Of these, six had Raynaud's phenomenon, all had been on corticosteroids, and one had digital vasculitis. The mean duration of corticosteroid...

BACKGROUND Revitalizing the necrotic subchondral bone and preserving the intact cartilage layer by retrograde drilling is the preferred option for treatment of undetached osteochondral lesions of the talus (OLT). We assessed the effectiveness of Endoscopic Core Decompression (ECD) in treatment of OLT. MATERIAL AND METHODS Seven patients with an undetached OLT of the medial talar dome underwent ...

Multilayer insulation (MLI) components are important parts of spacecraft, in which thin films the core elements. The film thicknesses generally small, between 10 and 30 μm, to reduce weight spacecraft. During launch a there is rapid drop internal pressure, causes gas flow out rapidly through component. resulting fluid force may cause damage failure, thereby directly affecting normal operation T...

BACKGROUND Osteonecrosis of the femoral head (ONFH) is an important indication for total hip arthroplasty in Taiwan. We demonstrated the etiologies of ONFH and outcomes based on stratification of patients according to different etiologies. METHODS We reviewed medical records and images from January 2000 to May 2010 in our database with the diagnosis of "osteonecrosis of the femoral head." We ...

BACKGROUND The aim of this study was to contrast the collapse values of the postoperative weight-bearing areas of different tantalum rod implant positions, fibula implantation, and core decompression model and to investigate the advantages and disadvantages of tantalum rod implantation in different ranges of osteonecrosis in comparison with other methods. MATERIAL AND METHODS The 3D finite el...

OBJECTIVES The aim of this study is to investigate the efficacy of fibula fixation in the early treatment of osteonecrosis of the femoral head (ONFH). METHODS 130 patients with ONFH were selected and randomly divided into control group and observation group. Patients in the control group received core decompression treatment, while patients in the observation group received fibula fixation. T...

Tantalum rod implant following core decompression is reported to be effective in early stage of osteonecrosis of the femoral head (ONFH). The purpose of this study was to assess the survivorship and prognostic factors for radiographic progression and conversion to total hip arthroplasty (THA) after treatment with a modified tantalum implant technology. 59 consecutive hips (45 patients) in whom ...

The constantly increasing complexity of polygonal models in interactive applications poses two major problems. First, the number of primitives that can be rendered at real-time frame rates is currently limited to a few million. Second, less than 45 million triangles – with vertices and normal – can be stored per gigabyte. While the rendering time can be reduced using level-of-detail (LOD) algor...
