Decarbonizing the fertilizers sector: an alternative pathway for urea and nitric acid production

François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos

In order to alleviate the environmental impact that nitrogen fertilizers production is responsible for, several efforts have been addressed to incentivize the partial or total decarbonization of the supply chains of ammonia and its derivatives. The decarbo ...

Protecting Mobile Food Diaries from Getting too Personal

Daniel Gatica-Perez, Lakmal Buddika Meegahapola

Smartphone applications that use passive sensing to support human health and well-being primarily rely on: (a) generating low-dimensional representations from high-dimensional data streams; (b) making inferences regarding user behavior; and (c) using those ...

Multi-objective optimization of utility systems and heat exchanger networks: method and application to the solar assisted hydrothermal gasification case

François Maréchal, Alberto Mian, Adriano Viana Ensinas, Emanuele Martelli

This work presents a novel framework for the multi-objective synthesis of utility systems and Heat Exchanger Networks (HEN) under single or multi-period operations. In order to solve the resulting Mixed Integer Non Linear (MINLP) programming problem, a bi- ...

Automatic generation of program execution that reaches a given failure point

George Candea, Cristian Zamfir

An execution of a target software program that causes a particular bug to manifest itself is generated. A target software program is received. A bug report generated by an execution of the target software program is received. The bug report describes a par ...

A dual representation for targeting process retrofit, application to a pulp and paper process

François Maréchal, David Brown

A method for the analysis of process energy requirements has been used to identify in an early design stage the potential process retrofit measures in an integrated pulp and paper mill. The minimum energy requirements (MER) of the process were computed by ...
