Performance analysis of jump-gliding locomotion for miniature robotics

Dario Floreano, Mirko Kovac, Jean-Christophe Zufferey

Recent work suggests that jumping locomotion in combination with a gliding phase can be used as an effective mobility principle in robotics. Compared to pure jumping without a gliding phase, the potential benefits of hybrid jump-gliding locomotion includes ...

Optimization of an Airborne Wind Energy System using Constrained Gaussian Processes with Transient Measurements

Colin Neil Jones, Ioannis Lymperopoulos, Sanket Sanjay Diwale

Airborne wind energy systems are built to exploit the stronger and more consistent wind available at high altitudes that conventional wind turbines cannot reach. This however requires a reliable controller design that can keep the airborne system flying fo ...

A Betz-Inspired Principle for Kite-Power Generation Using Tethered Wings

Dominique Bonvin, Grégory François, Sean Costello

This paper’s main contribution is a theoretical result that can be used to evaluate the maximum powergenerating potential of any kite-power system. An upper bound is derived for the power a wing can generate in a given wind speed. It is proven that the ang ...

Detection of Aircrafts on a Collision Course using Spatio-Temporal HOG

Pascal Fua, Vincent Lepetit, Artem Rozantsev, Christos Marios Christoudias

We have developed a method for the detection of both generic flight neighbouring aircrafts and those on a collision course. Our approach employs a sliding window linear Support Vector Machine (SVM) classifier with a Histogram of Oriented Gradients (HOG) fe ...

Evolution of the Aerodynamic Stability of an Oscillating Annular Compressor Cascade with Inlet Reverse Flow Condition Variations

Peter Ott, Virginie Anne Chenaux

While the advancement of computing hardware now enables accurate predictions of flutter and forced response at normal flow conditions during the compressor design phase, aeroelastic computations at off-design or reverse flow conditions remain a challenging ...

Enhanced second harmonic generation from InAs nano-wing structures on silicon

Eleonora Russo, Anna Dalmau Mallorquí, Ignasi Canales Mundet

We demonstrate morphology-dependent second-harmonic generation (SHG) from InAs V-shaped nanomembranes. We show SHG correlation with the nano-wing shape and size, experimentally quantify the SHG efficiency, and demonstrate a maximum SHG enhancement of about ...

An integrated fleet assignment and itinerary choice model for a new flexible aircraft

Michel Bierlaire, Matteo Salani, Bilge Atasoy

In this paper we present methodologies for improving the demand-responsiveness of air transportation systems. The main ingredients are the flexibility in transportation capacity provided by an innovative aircraft and an integrated model where supply-demand ...

A UAV Motor Denoising Technique to Improve Localization of Surrounding Noisy Aircrafts: Proof of Concept for Anti-Collision Systems

Hervé Lissek, Xavier Falourd, Patrick Marmaroli

Unmanned Aerial Vehicles (UAVs) have become very affordable and small in recent years, and are increasingly used in a wide range of monitoring and surveillance applications. A major problem when operating with swarm of UAVs is the risk of mid-air collision ...

Multiphase mixed-integer optimal control framework for aircraft conflict avoidance

Maryam Kamgarpour

This paper formulates the problem of aircraft conflict avoidance as a multiphase mixed-integer optimal control problem. In order to find optimal maneuvers, accurate models of aircraft nonlinear dynamics and flight envelop constraints are used. Wind forecas ...
