A computer program has been developed to calculate inviscid transonic flow over a swept wing in a wind tunnel with specified normal flow at the walls. An approximately orthogonal computational grid which conforms to the wing and the tunnel walls was developed for application of the JamesonCaughey finite volume algorithm. the full potential equations in fully conservative form using line relaxat...

Tunnel enlargement can appear after anterior cruciate ligament reconstruction. We investigated the influence of the bone block position of a patellar tendon autograft on the tunnel enlargement in the femur and in the tibia from two aspects. On the one hand, we examined the influence of the tunnel position in respect to the ap-diameter. On the other hand, we examined the influence of the bone bl...

Acromicric dysplasia is a skeletal dysplasia that is characterized by short stature, short hands and feet, typical facial dysmorphism, normal mental development, and characteristic hand radiology. Carpal tunnel syndrome may be seen in adults with acromicric dysplasia; however, to the authors' knowledge, it has not been reported in pediatric patients. This article describes a 9-year old boy with...

We aimed to assess the CT-based bony tunnel valuations and their correlation with knee function after patellar dislocation triple surgeries. A retrospective study was performed on 66 patients (70 knees) who underwent patellar dislocation triple surgeries. The surgery was MPFL reconstruction primarily, combined with lateral retinaculum release and tibial tubercle osteotomy. CT examinations were ...

This thesis presents the characterization of tunnel junctions and tunnel-junction-coupled lasers. The reverse-biased leakage current in a tunnel junction can be exploited to tunnel electrons from the valence band of one active region to the conduction band of a second active region. Thus, tunnel-junction-coupled lasers are highly efficient as they allow electrons to stimulate the emission of ph...

With the large-scale construction and rapid development of underground engineering, a large number of underground engineering construction, such as tunnel and subway emerged. The geological structure of the tunnel is complex and the roc is fragmented. Tunnel seismic image is a new geophysical technique. This method has advantages such as high resolution, high reliability and obvious image chara...

BACKGROUND This paper reports an in-vitro study for evaluating the influence of the femoral tunnel orientation in anterior cruciate ligament (ACL) double-bundle reconstructions. METHODS This work describes the experimental protocol and results obtained for six cadaver knees using the FlashPoint optical system (Image Guided, Boulder, Colorado, USA) and a computer-assisted technique for the ela...

NSIS Quality of Service (QoS) signaling enables applications to perform QoS reservation along a data flow path. When the data flow path contains IP tunnel segments, NSIS QoS signaling has no effect within those tunnel segments. Therefore, the resulting tunnel segments could become the weakest QoS link and invalidate the QoS efforts in the rest of the end-to-end path. The problem with NSIS signa...

excess pore pressure under seismic loadings has always been a main concern in geotechnical engineering practices. the phenomenon in soil can cause an effective stress and hence cause the shear strength of the soil to decrease considerably and large deformations to occur in the area. generally, increases in pore pressure occur in un-drained conditions. if it is formed, its consequences decrease ...
