• #### ﻿﻿Blisk blades manufacturing technologies analysis ﻿

(2019-06)
The paper presents blisk blades manufactured by different manufacturing processes. In this sense, different milling trajectories are presented, and, super abrasive machining strategies and EDM technologies are also tested. ...
• #### Borehole Resistivity Simulations of Oil-Water Transition Zones with a 1.5D Numerical Solver ﻿

(2020)
When simulating borehole resistivity measurements in a reservoir, it is common to consider an oilwater contact (OWC) planar interface. However, this consideration can lead to an unrealistic model since in the presence of ...
• #### Characterizing envelopes of moving rotational cones and applications in CNC machining ﻿

(2020-10)
Motivated by applications in CNC machining, we provide a characterization of surfaces which are enveloped by a one-parametric family of congruent rotational cones. As limit cases, we also address ruled surfaces and their ...
• #### Combined model-based and machine learning approach for damage identification in bridge type structures ﻿

(2022-06)
In this work, we propose a combined approach of model-based and machine learning techniques for damage identification in bridge structures. First, a finite element model is calibrated with real data from experimental ...
• #### Compensation effect analysis in DIE method for through-casing measuring formation resistivity ﻿

(2011-08)
The measuring technique based on Double-Injection-Electrodes (DIE) and its compensation arithmetic method have been proven to be very useful for eliminating the errors caused by electrode-scale mechanical tolerances in ...
• #### Computational cost estimates for parallel shared memory isogeometric multi-frontal solvers ﻿

(2014-12-31)
• #### Discrete maximum principles for nonlinear parabolic PDE systems ﻿

(2012-12-31)
Discrete maximum principles (DMPs) are established for finite element approximations of systems of nonlinear parabolic partial differential equations with mixed boundary and interface conditions. The results are based on ...
• #### Discrete nonnegativity for nonlinear cooperative parabolic PDE systems with non-monotone coupling ﻿

(2013-12-31)
Discrete nonnegativity principles are established for finite element approximations of nonlinear parabolic PDE systems with mixed boundary conditions. Previous results of the authors are extended such that diagonal dominance ...
