Heterogeneous parallel systems are becoming mainstream computing platforms nowadays. One of the main challenges the development community is currently facing is how to fully exploit the available computational power when porting existing programs or develo ...
In this paper we propose the Middle-Axis-Rotation (MAR) parametrization of human limbs that addresses the ill-conditioned cases of analytical Inverse Kinematics (IK) algorithms. The MAR parametrization is singularity-free in the reach space of the human li ...
Space is at the core of many environmental problems. From everyday objects to large infrastructures the way we construct things has an impact on issues at global scale… ...
The canton of Valais can be considered, in many respects, as a synecdoche of the Swiss territory. Presenting many linguistic, cultural or economical polarities that extend over short distances, exacerbating the tension between the ecumene and the ereme, su ...
Integrated optics has distinct advantages for applications in space because it integrates many elements onto a monolithic, robust chip. As the development of different building blocks for integrated optics advances, it is of interest to answer the importan ...
During the last decades, geography has lost its epistemological exceptionality, but is this enough? Social sciences are commonly threatened by methodological nationalism and, more generally, by methodological communalism, that is the corruption of a scient ...
We present a new algorithm for computational caustic design. Our algorithm solves for the shape of a transparent object such that the refracted light paints a desired caustic image on a receiver screen. We introduce an optimal transport formulation to esta ...
The main topic of this presentation is the justification of the interview protocol developed in my doctoral research, a research that studies the collective representations of what a just space is, for the city-society of the Metropolitan Area of Porto. Th ...
l existe une ambiguïté sur la réalité de la présence de l’espace au cinéma. On pourrait dire que le cinéma est, par excellence, un art spatial. En fait, on peut discuter, avec des arguments forts, cette évidence apparente. Cet article s’intéresse plus part ...
The modern expressions for polarization P and orbital magnetization M are k-space integrals. But a genuine bulk property should also be expressible in r space, as an unambiguous function of the ground-state density matrix, "nearsighted'' in insulators, ind ...
