Three- or Two-Stage Stochastic Market-Clearing Algorithm?

Sidi-Rachid Cherkaoui, Farzaneh Abbaspourtorbati, Antonio J. Conejo

As the power industry considers moving from a deterministic paradigm to a stochastic one to clear the day-ahead market in systems with significant stochastic production, the following question arises: how should a stochastic clearing algorithm be formulate ...

Urbaniser la campagne : la Chine, entre croissance massive et réalité du territoire

Marlène Audrey Bertille Leroux

The primary goal of this research is to undertake an analytical study addressing the urbanisation of rural areas as a major territorial, environmental and cultural challenge. The new relations that have developed between urban and rural areas clearly signa ...

Incremental Model Identification using the Concept of Extents

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

Kinetic models contribute greatly to cost reduction during the process development phase and are also helpful for process monitoring and control purposes. Kinetic models describe the underlying reactions, mass transport and operating conditions of the reac ...

Incremental model identification of gas-liquid reaction systems

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

Identification of kinetic models is an important task for monitoring, control and optimization of industrial processes. Kinetic models are often based on first principles, which describe the evolution of the states – numbers of moles, temperature and volum ...

Fixed-order H-infinity and H-2 Controller Design for Continuous-time Polytopic Systems: An LMI-based Approach

Alireza Karimi

In this paper, a convex set of fixed-order H-infinity and H2 dynamic output-feedback controllers for continuous-time systems with polytopic uncertainty is proposed. This approach is based on the use of some instrumental stable matrices, which operate as a ...

Simultaneous or incremental identification of reaction systems ?

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

Identification of kinetic models is essential for monitoring, control and optimization of industrial processes. Robust kinetic models are often based on first-principles and described by differential equations. Identification of reaction kinetics, namely r ...

Paradoxical Evidence Integration in Rapid Decision Processes

Michael Herzog, Wulfram Gerstner, Johannes Rüter, Nicolas Marcille

Decisions about noisy stimuli require evidence integration over time. Traditionally, evidence integration and decision making are described as a one-stage process: a decision is made when evidence for the presence of a stimulus crosses a threshold. Here, w ...

Simultaneous Modeling of Endogenous Influence of Urban Form and Public Transit Accessibility on Distance Traveled

Laetitia Bettex, Luis Fernando Miranda Moreno

This paper describes an attempt to understand better the endogenous relationships between urban form, accessibility to public transit, and daily travel distance. A model of two simultaneous equations was implemented. The model took into account the interac ...

A Two-Step Procedure for Estimating the Parameters in Mass-Balance-Based Bioprocess Models

Benoît Chachuat, Olivier Bernard

In this paper, we consider a two-step procedure for estimating the parameters in mass-balance based bioprocess models. In the first step, the values or combinations of the yield coefficients are calculated from mass-balance considerations without formulati ...
