49 A n elegant and versatile technique, line integral convolution (LIC) 1,2 represents directional information via patterns of correlation in a texture. Although most commonly used to depict 2D flow, or flow over a surface in 3D, LIC methods can also portray 3D flow through a volume. 1,3 However, the popularity of LIC as a device for illustrating 3D flow has historically been limited by the com...

Objective(s): Nanobodies, the single domain antigen binding fragments of heavy chain-only antibodies occurring naturally in camelid sera, are the smallest intact antigen binding entities. Their minimal size assists in reaching otherwise largely inaccessible regions of antigens. However, their camelid origin raises a possible concern of immunogenicity when used for human therapy. Humanization is...

Three-dimensional (3D) networks of carbon nanotubes (CNTs) were fabricated on a pillarpatterned substrate by plasma-enhanced chemical vapor deposition (PECVD). To fabricate 3D networks of CNTs, highly crystalline single-walled CNTs (SWCNTs) should be synthesize on the substrate. PECVD has advantages for low temperature growth and alignment of CNTs on the substrate, but it is difficult to synthe...

In all our experiments, at training time we pick top 2000 RPN generated 3D proposals using NMS (non-maximum suppression). At test time we select top 1000 3D proposals. However, a lower number of proposals, e.g. top 300 proposals does not effect the detection performance, and increase the test time detection speed significantly. In Section 3.2, we show that extracting less number of 3D proposals...

The formation and evolution of 3D synthetic jets is examined using direct numerical simulations. The primary focus of the current study is on examining the formation of 3D synthetic jets and the effect of changes in the jet aspect-ratio on the flow produced by the jet. Jets in quiescent and cross-flow cases are investigated. The study compares the vortex dynamics, velocity profiles and the othe...

Focusing on the visual effect deficiency in the application of standard LOD algorithm for 3D landscape design, 3D landscape designing model based on terrain complexity collision and shading rendering is built in this paper. First, 3D landscape design models are devided into two categories, regular terrain and irregular terrain, and different rules are respectively adopted during model building....

the aim of radiation therapy treatment planning is to achieve an optimal balance between delivering a high dose to target volume and a low dose to healthy tissues. in order to refrain any complications resulting from the dose to the surrounding normal organs, the role of treatment plan has been critically evaluated in term of how large the volume or mass of normal tissues exposed in the radiati...

The success of the 3D-printing process depends upon the proper selection of process parameters. However, the majority of current related studies focus on the influence of process parameters on the mechanical properties of the parts. The influence of process parameters on the shape-memory effect has been little studied. This study used the orthogonal experimental design method to evaluate the in...
