Ranked preference data arise in the situation that a large number of people (voters) rank several objects (candidates) in order of their extent of preference, for instance, multiple voting with ranking or a questionnaire of preference ranking. Such data are supposed to include the information about similarity among candidates in the sense that those who are highly preferred by the same voter wo...

To increase the maximum span of cable-stayed bridges, Uwe Starossek has developed a modified statical system. The basic idea of this new concept is the use of pairs of inclined pylon legs that spread out longitudinally from the foundation base or from the girder level. Spread-pylon cable-stayed bridge has distinct advantage like reduction of sag of cables and oscillation of cable during earthqu...

Existing real-time audio rendering architectures provide rigid development frameworks which are not adapted to a wide range of applications. In particular, experimenting with new rendering techniques is virtually impossible. In this paper, we present a novel, platform-independent software architecture that is well suited for experimenting with multichannel audio mixing, geometrical acoustics an...

Haliangicin is a beta-methoxyacrylate-type polyene antibiotic isolated from the unique marine myxobacterium Haliangium ochraceum. A further investigation of the extract of this microorganism has resulted in the isolation of haliangicin as well as its geometrical isomers. The configuration of the epoxide in haliangicin, which was unknown previously, was determined in this study. The planar struc...

In this paper we address the issue of a creeping wave by investigating a twodimensional configuration which involves a surface-braking crack in a traction free planar backwall. We assume that this back-wall is irradiated by a shear Gaussian beam which is incident at a critical angle and hits the wall away from the crack edge. We show that the generated wave known in the engineering literature a...

Two-dimensional (2D) materials provide a platform for strong light-matter interactions, creating wide-ranging design opportunities via new-material discoveries and new methods for geometrical structuring. We derive general upper bounds to the strength of such light-matter interactions, given only the optical conductivity of the material, including spatial nonlocality, and otherwise independent ...

We present a component-based, trainable system for detecting frontal and near-frontal views of faces in still gray images. The system consists of a two-level hierarchy of Support Vector Machine (SVM) classifiers. On the first level, component classifiers independently detect components of a face. On the second level, a single classifier checks if the geometrical configuration of the detected co...

Any practical realization of entanglement-based quantum communication must be intrinsically secure and able to span long distances avoiding the need of a straight line between the communicating parties. The violation of Bell's inequality offers a method for the certification of quantum links without knowing the inner workings of the devices. Energy-time entanglement quantum communication satisf...

We present analytical simulations for the performance of nanocoaxial and -hemispherical drift-limited solar cells, to determine optimal geometrical configuration and to interpret results of experimental nanocoaxial solar cell arrays. The material system considered in these simulations is hydrogenated amorphous silicon (a-Si:H), with solar cells designed in an n–i–p stack. Simulations conducted ...

Multiple plasmonic Fano resonances are generally considered to require complex nanostructures, such as multilayer structure, to provide several dark modes that can couple with the bright mode. In this paper, we show the existence of multiple Fano resonances in single layer core-shell nanostructures where the multiple dark modes appear due to the geometrical symmetry breaking induced by axial of...
