Computational methods for multi-criteria decision support in urban planning

Urbanization and climate change induce many challenges for todayâs cities. These challenges have to be faced by urban planners during complex planning processes that involve many stakeholders. Interactive computational approaches can provide assistance d ...

Global well-posedness for the Yang-Mills equation in 4+1 dimensions: Small energy

Joachim Krieger, Daniel Tataru

We consider the hyperbolic Yang-Mills equation on the Minkowski space

\reels^{4+1}

. Our main result asserts that this problem is globally well-posed for all initial data whose energy is sufficiently small. This solves a longstanding open problem. ...

Using Electromagnetic Time Reversal to Locate Faults in Transmission Lines: Definition and Application of the Mirrored Minimum Energy Property

Mario Paolone, Zhaoyang Wang, Reza Razzaghi, Asia Codino

This paper presents an application of the Electro-magnetic Time Reversal (EMTR) in changing media to identify the fault location along a single-conductor transmission line. It is shown that the time-reversed quantities exhibit a property, called Mirrored M ...

An Inexact Ultra-low Power Bio-signal Processing Architecture With Lightweight Error Recovery

David Atienza Alonso, Giovanni Ansaloni, Ruben Braojos Lopez, Soumya Subhra Basu, Loris Gérard Duch

The energy efficiency of digital architectures is tightly linked to the voltage level (Vdd) at which they operate. Aggressive voltage scaling is therefore mandatory when ultra-low power processing is required. Nonetheless, the lowest admissible Vdd is oe ...

Shock waves from nonspherical cavitation bubbles

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Outi Supponen, Marc Tinguely

We present detailed observations of the shock waves emitted at the collapse of single cavitation bubbles using simultaneous time-resolved shadowgraphy and hydrophone pressure measurements. The geometry of the bubbles is systematically varied from spherical ...

Constraints on violation of Lorentz invariance from atmospheric showers initiated by multi-TeV photons

Sergey Sibiryakov

Parameterizing hypothetical violation of Lorentz invariance at high energies using the framework of effective quantum field theory, we discuss its effect on the formation of atmospheric showers by very-high-energy gamma rays. In the scenario where Lorentz ...

Establishing links for the planning of sustainable districts

François Maréchal, Jessen Page, Nils Christian Schüler, Sébastien Cajot

Cities can play a key role in mitigating climate change impacts, as they represent two thirds of the world’s energy consumption and greenhouse gas emissions. This paper presents a model-based approach to support cities in the challenge of including energy ...

Morfología urbana Mediterránea

The city is a very complex system in which many parameters converge. The large number of these parameters greatly hinders not only an accurate analysis of all of them, but also the assessment of the phenomena that occur in the city and its impact on the en ...

Interactive optimization for planning of urban energy systems using parallel coordinates

François Maréchal, Jessen Page, Nils Christian Schüler, Sébastien Cajot

Early-stage urban planning is a complex discipline for spanning over a multitude of aspects and scales while lacking quantified information. Energy is only one of these aspects but crucial to include already at this planning phase in order to achieve globa ...
