OBJECTIVE The aim of this study was to evaluate the correlation between the Manchester scale and foot pressure distribution in patients with hallux valgus deformity. METHODS The study included 152 feet of 87 patients with hallux valgus and a control group of 391 feet of 241 individuals without hallux valgus deformity. The severity of hallux valgus was determined using the Manchester scale gra...

PURPOSE To assess the effects of positioning and notching of resurfaced femurs on the mechanical strength of third-generation saw bone (TGSB) femurs using an in vitro analogue bone model. METHODS 30 TGSB femurs were equally divided into 6 resurfaced femur groups (intact, anatomic, varus, valgus, anatomically notched, and valgus notched) for testing the load to failure, stiffness, and total en...

Multiple choice (MC) prøver som eksamensformat har eksisteret længe, og deres anvendelse er udbredt internationalt. Som prøveformat komplementerer MC-prøver de øvrige skriftlige prøve-formater, dets muligheder værd at kende til for fleste undervisere. Med udviklingen af moderne undervisningsteknologi spiller MC-spørgsmål sandsynligvis en stigende rolle på danske universiteter, ikke mindst i for...

This study presents a design method for the continuous switching test circuits of power devices. Depending on relationship between rated voltage DC source and device under (DUT), two types are proposed. These comprise cascaded buck-boost (or boost-buck) converter to achieve regeneration. Based analysis circuits, is proposed ensure that any failure does not spread circuit even when DUT fails dur...

Purpose: The purpose of this study was to investigate the relationship between hip and knee strength with knee valgus angle during drop jump in elite female athletes. Methods: Forty female athletes (mean ± SD age, 21.5 ± 1.99 years height, 169.08 ± 8.25 cm body mass, 61.05 ± 10.06 kg) participated in this study. Isometric hip and knee muscles strength were evaluated using standard clinical...

According to aggressive process scaling, reliability issues on semiconductor devices are becoming dominant such as variability, temporal failure and aging degradation. Temporal failures are mainly caused by alpha particles from packages or neutrons from outer space. These particles generate electron-hole pairs to flip memory or flip-flops, which is so-called soft errors. Alpha particles can be ...

A COMPARISON OF CYCLIC VALGUS LOADING ON RECONSTRUCTED ULNAR COLLATERAL LIGAMENT OF THE ELBOW. Roshan P. Shah, Derek P. Lindsey, Gannon W. Sungar, Timothy R. McAdams. Section of Sports Medicine, Department of Orthopaedic Surgery, Stanford University, Stanford CA. (Sponsored by Michael J. Medvecky, Department of Orthopaedic Surgery, Yale University School of Medicine.) This study compares the bi...

Runtime validation of wireless protocol implementations cannot always employ direct instrumentation of the device under test (DUT). The DUT may not implement the required instrumentation, or the instrumentation may alter the DUT’s behavior when enabled. Wireless sniffers can monitor the DUT’s behavior without instrumentation, but they introduce new validation challenges. Losses caused by wirele...

For reducing the test application time and required tester pins per device, we propose the use of multi-valued logic (MVL) signals, which increases data rate between the device under test (DUT) and automatic test equipment (ATE). An MVL signal sends multiple bits of information per clock cycle on a physical channel. Conversion of signals between binary andMVL is accomplished by digital to analo...

BACKGROUND Knee valgus and varus morbidity is at the second top place in children lower limb deformity diseases. It may cause abnormal stress distribution. The magnitude and location of contact forces on tibia plateau during gait cycle have been indicated as markers for risk of osteoarthritis. So far, few studies reported the contact stress and force distribution on tibial plateau of valgus kne...
