A new instrument used for treating femoral head osteonecrosis was recently proposed: the umbrella-shaped, Ni-Ti memory femoral head support device. The device has an efficacy rate of 82.35%. Traditional radiographic study provides limited information about the mechanical behaviour of the support device during an implant operation. Thus, this study proposes a finite element analysis method, whic...

This paper presents our approach for exploring the design space of input devices for three-dimensional graphics applications. We use an extended input device taxonomy as an inspiring source for generating permutations of sensors to suggest sensor configurations for new input devices. The taxonomy uses the integrated and separated degrees of freedom of an input device as a major classification c...

An automated system is described for the sensor-based precision docking and manipulation of large objects. Past work in the remote handling of large nuclear waste containers is extensible to the problems associated with the handling of large objects such as coils of flat steel in industry. Computer vision and ultrasonic proximity sensing as described here are used to control the precision docki...

(1) Objective: Keloid and hypertrophic scars are a challenge in clinical management, causing functional psychological discomfort. These pathological caused by proliferation of dermal tissue following skin injury. The TGF-β/Smad signal pathway the fibroblasts myofibroblasts is involved scarring process fibrosis. Today, multiple therapeutic strategies that target evaluated to attenuate aberrant s...

This paper proposes a novel way to realize augmented reality (AR) systems. Unlike previous AR systems, which use head-mounted or head-up displays, our approach employs a palmtop-sized video see-through device to present computer augmented view of the real world. This conguration, which w e call the magnifying glass approach, has several advantages over traditional head-up or head-mounted congur...
