AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Abstract of the book: While the importance of innovation to economic development is widely understood, the conditions conducive to it remain the focus of much attention. This volume offers new theoretical and empirical contributions to fundamental question ...
Does R&D have an impact on firm growth, profits, and value? To most observers, the obvious answer is yes. However, the recent report by Booz-Allen-Hamilton (BAH 2006) seems to conclude that the share of spending devoted to research has no relationship to t ...
Latest fabrication technologies of self-assembly nano-circuits (carbon nanotubes, silicon nanowires, etc.) have deployed bottom-up techniques that reach feature sizes well below 65nm, holding great promise for future large silicon-based integrated circuits ...
The aim of this thesis is to understand the dynamics of the growth of catalyst-free III-V semiconductor nanostructures on silicon substrates, focusing the attention mainly on the early stages of growths. A detailed understanding of this first phase of the ...
Open government is emerging as a core issue for increasing, on the one hand, participation of citizens, and, on the other hand, accountability, transparency, and the capability of delivering digital services by Public Administrations, with a consequent int ...
Integrated natural resources management is an emerging discipline that aims to move beyond piecemeal approaches and promote integrated actions over a wide range of disciplines and actors. One of the technical challenges of this new discipline is the integr ...
Thanks to their special interaction with light, semiconductor nanowires have opened new avenues in photonics, quantum optics and solar energy harvesting. One of the major challenges for their full technological deployment has been their strong polarization ...
In livestock genetic resource conservation, decision making about conservation priorities is based on the simultaneous analysis of several different criteria that may contribute to long-term sustainable breeding conditions, such as genetic and demographic ...
The ongoing scaling and hybridisation of manufacturing technologies enables us to attain unprecedented levels performance as well as to integrate electronic and fluidic circuits with sensors and actuators. Smart micro/nano systems will be the building bloc ...
In this paper the effect of varying temperature, pressure and chemical precursors on the vapour-liquid-solid (VLS) growth of silicon nanowires (Si NWs) have been investigated. Some aspects of nucleation and growth mechanisms are discussed. Control on Si NW ...
