Flow of real hypersurfaces by the trace of the Levi form
 Mathematical Research Letters 6
, 1999
"... Let F0: N2n−1 → Cn, n ≥ 2, be a smooth immersion of a real (2n − 1)dimensional hypersurface in complex nspace. In this paper we study the CauchyRiemann analogue of mean curvature flow [H] in Riemannian geometry: We deform the initial hypersurface N0 = F0(N2n−1) in normal direction ..."

Monitoring and control of real power in RF plasma processing
 J. Electrochem. Soc
, 1991
"... Radiofrequency (RF) plasmas are widely used for materials processing in the manufacturing of integrated circuits, e.g., plasma etching and plasmaenhanced deposition. Presently, plasma processes exhibit differences for runs on "identical " reactors and longterm process drift. Also, it ..."

Multimodal diffusion geometry by joint diagonalization of Laplacians
, 2012
"... We construct an extension of diffusion geometry to multiple modalities through joint approximate diagonalization of Laplacian matrices. This naturally extends classical data analysis tools based on spectral geometry, such as diffusion maps and spectral clustering. We provide several synthetic and re ..."

We also show that many previous attempts to construct multimodal spectral clustering can be seen as particular cases
Geometry C
"... level abstractions such as trimmed NURBS. Detailed surface geometry can many times be rendered by use of texture maps. But as realism is added, more and more raw geometry is required, usually in the form of triangles. Position, color, and normal components of these in full floating point accuracy. ..."

Articulation of Mandarin Sibilants: a multiplane realtime MRI study
"... Production of sibilant fricatives by four speakers of Mandarin Chinese was examined using realtime Magnetic Resonance Imaging (rtMRI). Data were reconstructed at 33.18 frames per second in the midsagittal plane, and additionally acquired in a coronal plane intersecting the vocal tract behind the al ..."

Modified Virtual Reality for Intuitive Semantic Information Visualization
"... In order to make use of domain knowledge and thus to create less abstract visualizations of the available information, we propose to integrate information visualization techniques in 3D visualizations of the application subject. We describe a framework that is build on an ontology, an hierarchical ..."

We achieve this integration by modifying the real world geometry in several ways. Our concept helps nonexpert users to intuitively interact with the system
Determining the Absolute Orientation in a Corridor using Projective Geometry and Active Vision
 IEEE Trans. on Industrial Electronics

"... The capability of a mobile robot to determine its position in the environment (selflocalization) is a prerequisite for achieving autonomous navigation. An approach is proposed for determining the absolute orientation of an autonomous robot in a system of corridors, based on the projective geometry ..."

Basic Topics on Tropical Geometry and Singula.rities
"... berg, and other mathematicians have developed the ”tropical (algebraic) geometry ” [8]. Algebraic curves are tropicalized to piecewiselinear curves. The method was used to construct topological types of real algebraic curves in Hilbert’s 16th problem [24]. In this rough sketch, we present several b ..."
