Prony Series Representation for the Lightning Channel Base Current

In this paper, a new representation for the lightning channel base current is proposed in terms of the so-called Prony series, obtained by means of a modified time-domain variant of the well-known vector fitting technique. This method allows both to reprod ...

Learning to use novel objects: A training study on the acquisition of novel action representations

Michiel van Elk, Christian Pfeiffer

Many studies have suggested that the motor system is organized in a hierarchical fashion, around the prototypical end location associated with using objects. However, most studies supporting the hierarchical view have used well-known actions and objects th ...

Efficient use of accessibility in microRNA target prediction

Jiri Vanicek, Ray Marcel Marin Florez

Considering accessibility of the 3'UTR is believed to increase the precision of microRNA target predictions. We show that, contrary to common belief, ranking by the hybridization energy or by the sum of the opening and hybridization energies, used in curre ...

OctoMag: An Electromagnetic System for 5-DOF Wireless Micromanipulation

Ali Sengül

We demonstrate five-degree-of-freedom (5-DOF) wireless magnetic control of a fully untethered microrobot (3-DOF position and 2-DOF pointing orientation). The microrobot can move through a large workspace and is completely unrestrained in the rotation DOF. ...

It was easy, when apples and blackberries were only fruits

Karl Aberer, Zoltán Miklós, Surender Reddy Yerva

Ambiguities in company names are omnipresent. This is not accidental, companies deliberately chose ambiguous brand names, as part of their marketing and branding strategy. This procedure leads to new challenges, when it comes to finding information about t ...

Strategy construction for parity games with imperfect information

Laurent Doyen

We consider two-player parity games with imperfect information in which strategies rely on observations that provide imperfect information about the history of a play. To solve such games, i.e., to determine the winning regions of players and corresponding ...

Gaze Behaviors for Virtual Crowd Characters

Daniel Thalmann, Jonathan Maim, Helena Stephanie Grillon Le Gallennec, Barbara Yersin

Nowadays, crowds of virtual characters are used in many domains such as neurosciences, psychology, and computer sciences. Since as human beings, we are natural experts in human being representation and movement, it makes it that much harder to correctly mo ...

A note on the representation of parametric models for multivariate extremes

Marc-Olivier Boldi

In this note, the representations of extremal Dirichlet and logistic distributions are reviewed and extended. These new representations allow exact simulations of the spectral distribution functions and an extension of the extremal logistic case to dimensi ...

Fair Welfare Maximization

Thomas Alois Weber, Ashish Goel

We consider the general problem of finding fair constrained resource allocations. As a criterion for fairness we propose an inequality index, termed “fairness ratio,” the maximization of which produces Lorenz-undominated, Pareto-optimal allocations. The fa ...

Simulating gaze attention behaviors for crowds

Daniel Thalmann, Helena Stephanie Grillon Le Gallennec

Crowd animation is a topic of high interest which offers many challenges. One of the most important is the trade-off between rich, realistic behaviors, and computational costs. To this end, much effort has been put into creating variety in character repres ...
