This study investigated the performance and aeroelastic characteristics of a wind turbine blade based on strongly coupled approach (two-way fluid structure interaction) to simulate the transient FSI[1] responses of HAWT[2]. Aerodynamic response was obtained by 3D CFD-URANS approach and structural response was obtained by 3D Finite element method. ...

In addition to medical recognition applications, X-ray CT-scan images are increasingly found to have more innovative and widespread applications. Due to the ability of producing high resolution and high contrast images from soft tissues with low attenuation coefficients, the usage of X-ray micro-focus source, which has a very small focal point (in the range of micrometer), plays an important ro...
Several methodologies published in the literature can be used to construct realistic pore networks for simple rocks, whereas in complex pore geometry formations, as formed in tight reservoirs, such a construction still remains a challenge. A basic understanding of pore structure and topology is essential to overcome the challenges associated with the pore scale modeling of tight porous media. A...
In the frame work of relativistic density functional theory, using full potential local orbital band structure scheme (FPLO), the magnetic properties of single 3d transition metals (3d-TM) adsorbed on 2D hexagonal boron nitride (2D h-BN) are investigated. Binding energies between 3d-TM adatoms and 2D h-BN in three different compositions, local spin magnetic moments of 3d-TM and total spin magne...
Throughout human history, the most valuable inventions have been those that, even decades after their initial introduction, affected the lives of people around the world. 3D printers similar to steam engines, light bulbs, and the World Wide Web are thought to be among the inventions that will revolutionize the future of different industries. This technology is generally introduced as the manuf...
in this paper, an object-based, highly scalable, lossy-to-lossless 3d wavelet coding approach for volumetric medical image data (e.g. mr and ct) is proposed. the new method, called 3dobhs-spiht, is based on the well known set partitioning in hierarchical trees (spiht) algorithm and supports both quality and resolution scalability. the 3d input data is grouped into groups of slices (gos) and eac...
shaded pole induction motors, despite the simplicity and low cost, are difficult to analyze particularly in the equivalent circuit methods, due to the asymmetric structure, saturation, harmonics, inaccurate estimation of leakage inductances and skew. hence, 3d numerical methods could be very useful in the design and optimization stage. this paper presents the 3d transient finite element analysi...
We perceive real-world objects as three-dimensional (3D), yet it is unknown which brain area underlies our ability to perceive objects in this way. The macaque inferotemporal (IT) cortex contains neurons that respond selectively to 3D structures defined by binocular disparity. To examine the causal role of IT in the categorization of 3D structures, we electrically stimulated clusters of IT neur...
background: collagen-based three-dimensional (3d) in vitro systems have been introduced to study the physiological states of cells. as a biomolecule, collagen is usually extracted from terrestrial animals whilst aquatic animals like squid contain large amounts of collagen. methods: in order to make effective use of marine organisms, we selected persian gulf squid in 2015 to extract the required...
