The Autonomous Photovoltaic MarXbot

Francesco Mondada, Philippe Rétornaz, Florian Christopher Vaussard, Martin Olivier Liniger

Domestic service robots are currently powered by the mains electricity. The growing multiplication of such devices negatively impacts our environment. In this study, we show the feasibility of harvesting energy from natural light in an indoor environment. ...

Electric field within lightning protection volume in presence of a descending leader

Electric field distributions within lightning protection volume of a single lightning rod are studied for the case of a vertical downward leader. The boundaries of volumes with the electrical strength exceeding its critical value for ionization in air are ...

Design and Analysis of NoCs for Low-Power 2D and 3D SoCs

Giovanni De Micheli, Luca Benini, Srinivasan Murali, Ciprian Seiculescu

Networks-on-Chip (NoC), being a system-level interconnect, can play a major role in achieving low-power SoC designs. In many designs, the cores are grouped in to Voltage Islands (VIs). To reduce the leakage power consumption, an island containing cores tha ...

Cyclotron Designs for Ion Beam Therapy with Cyclinacs

Adriano Garonna

This thesis presents new superconducting compact (as opposed to separated-sector ) cyclotron designs for injection in CABOTO, a linac developed by the TERA Foundation delivering C6+/H2+ beams up to 400 MeV/u for ion beam therapy. This association of a vari ...

NoC Topology Synthesis for Supporting Shutdown of Voltage Islands in SoCs

Giovanni De Micheli, Luca Benini, Srinivasan Murali, Ciprian Seiculescu

In many Systems on Chips (SoCs), the cores are clustered in to voltage islands. When cores in an island are unused, the entire island can be shutdown to reduce the leakage power consumption. However, today, the interconnect architecture is a bottleneck in ...

Climate change and its influence on the planning and operation of electric power systems

Edgard Gnansounou, Raphaël Barben

The IPCC Report (Intergovernmental Panel on Climate Change 2007) raises serious concerns about the increase of extreme weather events (storms, rains, snowfalls). Over the past 100 years the average global temperature has risen by around 0.75°C and the sea ...

Multi-unit global energy management and optimization for network-on-chip applications

Zeynep Toprak Deniz

The problem of energy optimization in multi-core systems (such as single-chip multiprocessors) where the individual energy demands of various processing elements are governed by instantaneous workload requirements is well defined in literature. The signifi ...

Voltage peaks of low voltage induction motors due to PWM inverter supply

Jean-Jacques Simond, Basile Kawkabani

In industrial variable speed drives, the supply of low voltage induction motors by IGBT-PWM inverters through screened cables may cause dangerous over-voltage surges at the motors terminals. These voltage peaks of about twice the de link voltage, with a sh ...
