Investigating the Difference in Mechanical Stability of Retained Austenite in Bainitic and Martensitic High-Carbon Bearing Steels using in situ Neutron Diffraction and Crystal Plasticity Modeling

Metals, 2019
In situ neutron diffraction of the uniaxial tension test was used to study the effect of the surrounding matrix microstructure on the mechanical stability of retained austenite in high-carbon bearing steels.

The coordinate system transformation of a serial kinematic structures and use in the derivation of systems motion equations

MATEC Web of Conferences, 2016
This text discusses the use of transformation matrices to determine the motion equations of the complex mechanical structure. Use of the transformation matrix does not apply only to motion equations but has the general use in relative positions determine

Revisiting the Mathematical Model for Determining Coordinates of Points in a Trimetric Projection

Mathematics
In a recent article in this journal, Nikolić et al. presented a mathematical model for computing the coordinates in the trimetric projection of a 3D object, in terms of the projections of unit areas on the three dihedral planes. We revisit this model and

Selective Downsampling for Fast and Accurate 3D Global Registration with Applications in Medical Imaging

Mathematics
Robust global point-cloud registration remains a key challenge in robotic neurosurgery, particularly for markerless patient registration, where anatomical surface acquisition can be incomplete and noisy. This paper proposes practical pre-processing steps,

Quantitative Analysis of 4 × 4 Mueller Matrix Transformation Parameters for Biomedical Imaging

Photonics, 2019
Mueller matrix polarimetry is a potentially powerful technique for obtaining microstructural information of biomedical specimens. Thus, it has found increasing application in both backscattering imaging of bulk tissue samples and transmission microscopic

Analysis of the algorythms accuracy of the plane and space geodetic coordinates transformation

Geodesy and Cartography, 2012
The accuracy of the coordinates computed by transformation from one system to another is analysed. Values of transformation parameters are computed by the least-square method taking into account the accuracy of the coordinates of the identical points in ...

Realization in Generalized State Space form for 2-D Polynomial System Matrices

Sultan Qaboos University Journal for Science, 2005
In this paper, a direct realization procedure is presented that brings a general 2-D polynomial system matrix to generalized state space (GSS) form, such that all the relevant properties including the zero structure of the system matrix are retained.

Privacy Protection by Matrix Transformation

IEICE Transactions on Information and Systems, 2009
Privacy preserving is indispensable in data mining. In this paper, we present a novel clustering method for distributed multi-party data sets using orthogonal transformation and data randomization techniques. Our method can not only protect privacy in face of collusion, but also achieve a higher level of accuracy compared to the existing methods.
