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 dissertation is concerned with the development of a methodology and appropriate tools for the investigation of chemical reaction systems using measured data. More specifically, the determination of reaction stoichiometry and kinetics from concentratio ...
Glucose and lactate profiles in Chinese hamster ovary cell cultures were accurately monitored in real time and in situ during three bioreactor batch cultures lasting 11, 15, and 15 days performed within a 60-day period. Monitoring was accomplished using in ...
A pulse height analysis (PHA) x-ray system has been successfully implemented on the tokamak TCV, aiming at a low cost monitor system of the plasma electron temperature and impurity content. To meet the need for high throughput and fast acquisition, mandato ...
A method to measure search engines, namely the quality of the pages in a search engine index, is presented. An algorithm is introduced to approximate the quality of an index by performing a random walk on the Web. This methodology is used to compare the in ...
Sinusoidal structured light projection (SSLP) technique, specifically- phase stepping method, is in widespread use to obtain accurate, dense 3-D data. But, if the object under investigation possesses surface discontinuities, phase unwrapping (an intermedia ...
A new method for the determination of low concentrations (0.03-35 mu M) of the aqueous ferrate (Fe(VI)) was developed. The method is based on the reaction of Fe(VI) with 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) which forms a green radical ...
Any innovative design of a chem. or biol. reactor has to consider the dynamics of the primary phys. and chem. steps involved in the overall process. For homogeneous highly viscous systems the mixing time is of crucial importance for the product quality. In ...
For many years, calorimetry has been recognized as a powerful and universal tool for monitoring chem. and biol. processes. A lab.-scale reaction calorimeter (RC1, Mettler-Toledo), initially developed for chem. reaction studies with a sensitivity of 100-150 ...
A method for the online calcn. of conversion rates and yield coeffs. under dynamic process conditions was developed. The method is based on cumulated mass balances using a moving av. method. Elemental balances were used to test the measured cumulated quant ...
We develop an estimation technique for problems that involve multiple sources of uncertainties or errors in the data. The method allows the designer to explicitly incorporate into the problem formulation bounds on the sizes of the uncertainties; thus leadi ...
