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.
The antistatic and hydrophilic properties of acrylic, polyamide, and polyester fibers were improved by treatment with a polymerizable vinyl monomer contg. an ammonium group and a polymerizable monomer contg. a carboxyl or sulfo group and irradiating. Thus, ...

The present invention discloses a device (CD) for converting a first motion (x s ) into a second motion ( y) responsive to said first movement (x s ) under a demagnification scale (i), comprising: a) an input portion (IP) being drivable in a rectilinear tr ...
The scope of this work has been the design of a mechanical actuator in polydimethylsiloxane (PDMS) / glass for precise liquid sampling, based on the electrochemical generation of O2. The device is composed of two chambers separated by a PDMS membrane. In t ...
This research work analyses Theo van Doesburg's Counter-constructions presented in Paris in 1923 at the "L'Effort Moderne" exhibition. These Counter-constructions stand as icons of the Modern Movement due to their role as precursors of a new "boundless" sp ...
This paper presents new implementations of a design method to obtain minimum energy adaptive structures. The design method was formulated in previous work [1, 2] for reticular structures equipped with sensors (e.g. strain, optical) and linear actuators. Th ...
To prepare bactericide textiles, TiO2 has been added in the form of colloid, powder or a combination of both and the TiO2 modified textiles subsequently cured at temperatures adapted to their specific heat resistance. The bactericide textile is activated a ...
This paper presents a method to detect the position of a linear actuator without any position sensor. The actuator winding has a resonance frequency that is very related to the position of the linear actuator Pmoving part. A sinusoidal scan voltage is supe ...
The goal of the project is to explore the possibility of controlling the speed of the actuator’s moving part without using any sensor. The speed has to be set accordingly to the position of the moving part at specific time. This dependency is fixed and is ...
