A method for the simultaneous spectrophotometric determination of nickel, cobalt and copper based on theformation of their complexes with 2-(2-Thiazolylazo)-p-Cresol (TAC) in micellar media of Triton X-100 isproposed. The absorbance spectra were recorded in the range of 500 to 800 nm. The linear concentrationrange for nickel, cobalt and copper in solution calibration sets were 0.05–1.80, 0.10–6...

Decomposing 3D building models into architectural elements is an essential step in understanding their 3D structure. Although we focus on landmark buildings, our approach generalizes to arbitrary 3D objects. We formulate the decomposition as a multi-label optimization that identifies individual elements of a landmark. This allows our system to cope with noisy, incomplete, outlier-contaminated 3...

The aim of this study is to introduce a stress-based non-binary contact model missing in classical discrete element method (DEM). To tackle issue, force-displacement law generalized by utilizing the trace particle stress tensor make all contacts dependent on other and thus, account for multiple simultaneously acting single particle. Simulation results uniaxial confined (oedometric) compression ...

We propose a numerical method for the finite element simulation of micro-swimmers composed several rigid bodies moving relatively to each other. Three distinct formulations are proposed impose relative velocities between bodies. validate our model on three-sphere swimmer, which analytical results available.
