Building three-dimensional pedestrian networks in cities
, 2020 With the rapid growth of automobile transport over the last century, conflicts between automobile and pedestrian transport have been viewed as a major concern in urban and transport planning. Elevated and underground pedestrian networks, which compensate

Three-Dimensional Circular Trapdoor Stability
, 2022 The stability of a circular opening trapdoor in undrained cohesive soils is numerically investigated using three-dimensional (3D) numerical simulations. FLAC3D, a finite difference program using the shear strength reduction method (SSRM), is employed to ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

THREE DIMENSIONAL ILLUSTRATING – 2D-3D TRANSFORM [PDF]
Studia Universitatis Babeş-Bolyai. Psychologia-Paedagogia, 2010 . We present in this paper a special computer technique, which can lead us to opportunities of making three dimensional pictures from two dimensional pictures (2D-3D conversion) and we give some examples of illustrating this.

Optimizing Image Focus for Shape From Focus Through Locally Weighted Non-Parametric Regression
IEEE Access, 2019 Shape from focus is a passive optical technique that uses multiple images with different focus levels. To compute the sharpness of each pixel in the image sequence, obtained by translating the object plane at a constant step size along the optical axis ...

Three-dimensional flow instability in a lid-driven isosceles triangular cavity
, 2011 Linear three-dimensional modal instability of steady laminar two-dimensional states developing in a lid-driven cavity of isosceles triangular cross-section is investigated theoretically and experimentally for the case in which the equal sides form a ...

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Comparison of algorithms for converting 3D objects into rolls, using a spiral coordinate system
Virtual and Physical Prototyping, 2017 The definition of a point’s location in volume by Cartesian, spherical and cylindrical coordinate systems requires three dimensions (x, y, z), (r, θ, ϕ) and (ρ, ϕ, z) accordingly.

Three-dimensional Echocardiography
European Cardiology Review, 2006 Although two-dimensional echocardiography (2DE) was a major step forward for the noninvasive assessment of cardiac structure and function, the diagnosis of complex disorders remained a difficult mental conceptualization process. In addition, the measurement of left ventricular volume and function, the most common referral reason for echocardiography ...

Three‐dimensional ultrasound [PDF]
Ultrasound in Obstetrics & Gynecology, 1995 The papers in this issue show that the feasibility of three-dimensional ultrasound methods in the clinical setting using commercially available equipment is nearby. Their results demonstrate some of the advantages compared to two-dimensional ultrasound and other diagnostic modalities, including reduced scanning times that will offer more cost-effective
