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.
Understanding stakeholders’ needs is necessary to design requirements for organizations and IT systems. We present a systemic modeling method to identify and categorize stakeholders within value networks, to analyze the relationships between these value ne ...
This paper describes the methodology used to transform the 2001 Swiss SAM devised at ETH Zürich and align it to the requirements of the GEMINI-E3 model which is based on the GTAP database. ...
An electronically switching-beam reflectarray antenna to be used in X-band has been designed, manufactured and tested, using PIN diodes as switching device. The antenna has 244 elements arranged in a circular aperture. With the aim of saving electronic dev ...

In this paper we describe a service modeling project done at an IT department that provides IT services to a network of state owned healthcare providers in the state of Vaud in Switzerland. The goal of the project is to un- derstand how to maintain busines ...
Intelligent Transportation Systems (ITS) can only operate successfully if selection and training of personnel is carried out in a systematic, theoretically sound way. Given the increasing responsibility of operators working in the control room, a scientifi ...
In this study, a dual frequency circularly polarized reconfigurable reflectarray (RA) cell with RF-MEMS switches is designed. RA combines the advantages of reflector-based and phased array antennas, providing a low-cost and high performance antenna array s ...

This communication presents a review of the developments carried out towards the electromagnetic modeling, design and practical implementation of the basic building block of a planar antenna for the reception of Ku-band satellite broadcasting services from ...
With the increasing requirement of a high-density, high-performance, low power alternative to traditional SRAM, Gain Cell (GC) embedded DRAMs have gained a renewed interest in recent years. Several industrial and academic publications have presented GC mem ...
Optical phased arrays are versatile components enabling rapid and precise beam steering. An integrated approach is followed in which a 1D optical phased array is fabricated on silicon-on-insulator. The optical phased array consists of 16 parallel grating c ...
Most civil structures are passive and static. They are designed according to serviceability and safety requirements. When subjected to actions, they generally deflect in a passive manner. For example, they do not adapt actively to external loading. A more ...
