On Planar Affine Transform Determination.

Comput. Artif. Intell., 1997
An effective direct method for determination of planar affine transform coefficients is described. It is based on construction of triangles defined by barycentric centroids of corresponding parts of reference and transformed images which are cut by straight lines determined by barycentric centroids. Numerical experiments performed have confirmed a good

A Direct Method for Estimating Planar Projective Transform [PDF]

, 2011
Estimating planar projective transform (homography) from a pair of images is a classical problem in computer vision. In this paper, we propose a novel algorithm for direct registering two point sets in R2 using projective transform without using intensity values.

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Capacitorless Solid-State Power Filter for Single-Phase DC-AC Converters

CES Transactions on Electrical Machines and Systems
Converters rely on passive filtering as a crucial element due to the high-frequency operational characteristics of power electronics. Traditional filtering methods involve a dual inductor-capacitor (LC) cell or an inductor-capacitor-inductor (LCL) T ...

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

Advanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Characteristics of a New Implantable Transformer with Planar Shape

IEEE Translation Journal on Magnetics in Japan, 1989
This paper describes the output characteristics of a new transformer for an implantable artificial heart. The implantable transformer consists of Co-base amorphous magnetic fiber and conductive fibers. Features include a thin, planar shape and high flexibility. A trial-fabricated transformer can supply an electric power of 10 W.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.
