Self-Structuring Of Cellular And Channel Type In Complex System Dynamics In The Framework Of Scale Relativity Theory

In the framework of Scale Relativity Theory, by analyzing dynamics of complex system structural units based on multifractal curves, both Schrodinger and Madelung approaches are functional and complementary. The Madelung selected approach involve synchronou ...

A proof of equivalence of two force methods for active structural control

Gennaro Senatore, Arka Prabhata Reksowardojo

This paper gives a proof of equivalence between two existing force methods (FM) for structural analysis: The Integrated Force Method (IFM) and a force method based on singular value decomposition (SVD) of the equilibrium conditions here named as SVD-FM. Re ...

Neutron Diffraction and Diffraction Contrast Imaging for Mapping the TRIP Effect under Load Path Change

Helena Van Swygenhoven, Efthymios Polatidis, Markus Strobl

The transformation induced plasticity (TRIP) effect is investigated during a load path change using a cruciform sample. The transformation properties are followed by in-situ neutron diffraction derived from the central area of the cruciform sample. Additio ...

Three-dimensional radiative transfer effects on airborne and ground-based trace gas remote sensing

Alexis Berne, Dominik Brunner, Thomas Wagner

Air mass factors (AMFs) are used in passive trace gas remote sensing for converting slant column densities (SCDs) to vertical column densities (VCDs). AMFs are traditionally computed with 1D radiative transfer models assuming horizontally homogeneous condi ...

Electron backscatter diffraction study of variant selection during ordering phase transformation in L1(0)-type red gold alloy

Roland Logé, Cyril Cayron, Margaux Nathalie Dominique Larcher

A shape-memory effect is known to appear in red gold alloys with compositions close to Au-Cu. The aim of this paper is to study by electron backscatter diffraction (EBSD) the variant selection in the A1 -> L1(0) transformation occurring under stress, in be ...

A Review and Mathematical Treatment of Infinity on the Smith Chart, 3D Smith Chart and Hyperbolic Smith Chart

Mihai Adrian Ionescu, Andrei Müller

This work describes the geometry behind the Smith chart, recent 3D Smith chart tool and previously reported conceptual Hyperbolic Smith chart. We present the geometrical properties of the transformations used in creating them by means of inversive geometry ...

Shape Memory Micro- and Nanowire Libraries for the High-Throughput Investigation of Scaling Effects

Jürgen Brugger, Shenqi Xie, Alfred Ludwig

The scaling behavior of Ti-Ni-Cu shape memory thin-film micro-and nanowires of different geometry is investigated with respect to its influence on the martensitic transformation properties. Two processes for the high throughput fabrication of Ti-Ni-Cu micr ...

Copper-catalysed cyanoalkylative cycloetherification of alkenes to 1,3-dihydroisobenzofurans: development and application to the synthesis of citalopram

Qian Wang, Jieping Zhu, Minh Tu Ha

A copper-catalysed cyanoalkylative cycloetherification of alkenes was developed. Heating a solution of substituted (2-vinylphenyl)methanol in MeCN/MeOH (v/v 7/3) in the presence of a catalytic amount of copper(II) tetrafluoroborate hydrate [Cu(BF4)26H2O], ...
