Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
This study presents a wireless power and data transmission system to overcome the problems in intracranial epilepsy monitoring associated with transcutaneous wires. Firstly, a wireless power transfer link based on inductive coupling is implemented and a po ...
This paper reports the design, fabrication, and testing of a soft electroactive polymer power generator that has a volume of 1cm(3). The generator provides an opportunity to harvest energy from environmental sources to power wireless sensor networks becaus ...
Recently, European Union advocates the smart Solid-State Lighting (SSL). The key factors are a smart-control scheme and an interaction with other networks, such as communication networks and traffic monitoring sensor networks. Public lighting represents a ...
The method of the invention, comprising at the user side: a) checking if the load of a first gateway to which a user terminal device is wirelessly connected, falls below a given low load threshold; b) if said first gateway load has fallen below said given ...
Approximately one billion users have access to mobile broadband, through which they intend to obtain the same data they can reach using a wired connection. Because of the cost of transmitting data over a mobile-broadband connection and given that 3G networ ...
This work studies how to build wireless network protocols that achieve better reliability, lower delay and higher throughput than existing alternatives by using network coding and by exploiting the broadcast nature of the wireless channel. In the first par ...
This paper considers a single source transmitting data to one or more receivers/users over a shared wireless channel. Due to random fading, the wireless channel conditions vary with time and from user to user. Each user has a buffer to store received packe ...
In this paper, we consider the problem of monitoring soil moisture evolution using a wireless network of in situ sensors. Continuously sampling moisture levels with these sensors incurs high-maintenance and energy consumption costs, which are particularly ...
This thesis evaluates the potential of Ultra Wideband Impulse Radio for wireless sensor network applications. Wireless sensor networks are collections of small electronic devices composed of one or more sensors to acquire information on their environment, ...
Highly miniaturized low-power drop-coated metal-oxide gas sensors on polyimide foil are presented. Drop-coating of SnO2-based material was successfully achieved on transducers as small as 15 μm on polyimide, a substrate compatible with the printed electron ...
