2022年6月25日 · Structure of IgA. Immunoglobulin A (IgA) is present in the serum as a 170 kDa, four polypeptide (two L and two H) chain protein. Its H-chain type is alpha (α). IgA exists in serum in both monomeric and dimeric forms. Although it exists primarily in monomeric form, followed by dimeric, trimeric and some tetrameric forms are also present.

2024年1月1日 · We develop an IGA shape optimization method to widen the band gap of periodic composite plates by optimize its thickness profile smoothly. The thickness, i.e., z-component of control point is defined as optimal design variable and the smooth thickness profile can be obtained with few control points.

Immunoglobulin A (IgA, also referred to as sIgA in its secretory form) is an antibody that plays a role in the immune function of mucous membranes. The amount of IgA produced in association with mucosal membranes is greater than all other types of antibody combined. [3]

Immunoglobulin A (IgA) plays a key role in defending mucosal surfaces against attack by infectious microorganisms. Such sites present a major site of susceptibility due to their vast surface area and their constant exposure to ingested and inhaled ...

2021年5月1日 · This characteristic makes IGA-BEM much suitable numerical technique for shape optimization problems. The advantages offered by this technique in shape optimization are evident e.g. unified design and analysis model calls off interaction with CAD model during the optimization process; reduce problem dimensionality and smoother boundaries in ...

2021年1月14日 · Shape optimization based on isogeometric analysis (IGA) has gained popularity in recent years. Performing shape optimization directly over parameters defining the computer-aided design (CAD) geometry, such as the control points of a spline parametrization, opens up the prospect of seamless integration of a shape optimization step into the CAD ...

2024年10月3日 · We present an open-source Python framework for the shape optimization of complex shell structures using isogeometric analysis (IGA). IGA seamlessly integrates computer-aided design (CAD) and...

2022年3月15日 · Isogeometric analysis (IGA) is a numerical method adopting the same spline representation for geometry representation and solution field. It requires a high-quality parameterization of the computational domain, in which decomposing the domain into a structure composed of quadrilateral (in 2D) or hexahedral (in 3D) patches is a key issue.

MSolve library that support the spatial discretization method of Isogeometric Analysis. .iga File reader. Generates an isogeometric model from Isogeometric Analysis files exported from Autodesk T-Spline plug-in fro Rhino. This reader support the generation of both planar T-Splines 2D geometries as well as T-Splines shells. Custom file readers.

Recently, Isogeometric analysis has evolved as a powerful tool for solving shape optimization problems. The purpose of this study is to see how successfully IGA can tackle shape optimization problems and how it performs in comparison to standard FEM.
