To evaluate the ankle functional instability (AFI) we proposed an analysis approach using the three-dimensional shape of the ankle posture. The three-dimensional shape acquisition system are used the structured light projection technique, which is composed by the digital still camera and the DLP projector. The feature is easily to solve correspondence problem between the projection pattern and camera...
We apply scanning probe microscopy (SPM) to study the morphology and electrical properties of vertical zinc oxide nanorods grown by hydrothermal methods on silicon substrates. It is demonstrated that - against the intuition - SPM techniques can indeed be used to study such fragile high-aspect ratio semiconductor nanorods. Atomic-force microscopy (AFM) operating in tapping mode yields - via the analysis...
Three-dimensional image surface reconstruction with cross-sectional images is a kind of significant model built upon the two-dimensional image in the digital image processing. It reconstructs the three-dimensional shape of the workpiece with a sequence of cross-sectional images. The three-dimensional image surface reconstruction method derived from computed tomography images is focused in this article...
RNA molecules are distinguished by their sequence composition and by their three-dimensional shape, called the secondary structure. The secondary structure of a pre-mRNA sequence may have a strong influence on gene splicing. In our previous work, we showed that a splice-site model employing sequence features built using our feature generation algorithm was very effective in predicting splice sites...
High-intensity fs-laser pulses permanently change the form of silver nanoparticles in glass and result in optical dichroism. Optical and small angle X-ray scattering experiments are shown which clarify the 3-dimensional shape of the resulting particles.
In total knee replacement surgery, also known as total knee arthroplasty, prosthetics are implanted in the knee joint as treatment for progressive diseases such as arthritis or trauma. In this paper, we aim to recover the 3-D shape of bones and prosthetic devices in patients who have undergone total knee replacement. Such an objective is addressed using a collection of 2-D X-rays acquired from multiple...
This paper presents an ultra-wide band stubby antenna that covers all current cell phone communication bands from 824 MHz to 6 GHz. The antenna has a volume of 5*8*30 mm3. The antenna is made of a folded V shape stamped sheet metal, which can be easily manufactured, and folded to form a three-dimensional shape. An efficiency of 55~65% was achieved over 824~960 MHz and an efficiency of 67~88% was achieved...
Summary form only given. In the laser cladding process, a molten pool of the pasted or blown powder with a complex three-dimensional shape is formed on the substrate, by the laser beam interaction with powder material. This interaction time plays a crucial role for the desired successful cladding. In our present analysis, we find that in a narrow range of power density and beam interaction time, the...
Transparency can be a useful device for simultaneously depicting multiple superimposed layers of information in a single image. However, in computer-generated pictures-as in photographs and in directly viewed actual objects-it can often be difficult to adequately perceive the three-dimensional shape of a layered transparent surface or its relative depth distance from underlying structures. Inspired...
