17 p, 476.7 KB A quasiconvex asymptotic function with applications in optimization / Martínez Legaz, Juan Enrique (Universitat Autònoma de Barcelona) ; Hadjisavvas, Nicolas (University of the Aegean) ; Lara, Felipe (Universidad de Tarapacá)
We introduce a new asymptotic function, which is mainly adapted to quasiconvex functions. We establish several properties and calculus rules for this concept and compare it to previous notions of generalized asymptotic functions. [...]

30 p, 729.0 KB Modelling human network behaviour using simulation and optimization tools : the need for hybridization / Gruler, Aljoscha (Universitat Oberta de Catalunya. Internet Interdisciplinary Institute (IN3)) ; Armas Adrián, Jésica de (Universitat Pompeu Fabra) ; Juan, Ángel A. (Universitat Oberta de Catalunya. Internet Interdisciplinary Institute (IN3)) ; Goldsman, David (Georgia Institute of Technology (Atlanta, Estats Units d'Amèrica))
The inclusion of stakeholder behaviour in Operations Research / Industrial Engineering (OR/IE) models has gained much attention in recent years. Behavioural and cognitive traits of people and groups have been integrated in simulation models (mainly through agent-based approaches) as well as in optimization algorithms. [...]

The mechanisms of plant trait adaptation and acclimation are still poorly understood and, consequently, lack a consistent representation in terrestrial biosphere models (TBMs). Despite the increasing availability of geo-referenced trait observations, current databases are still insufficient to cover all vegetation types and environmental conditions. [...]

God created this universe and all living and non-living entities. Human is one of the best among His creations and in Human beings, eyes are the best gift of God to see His creations. As of now, humans are considered as the only developed creatures among God's creations and have developed themselves from Stone Age to the Computing Era. [...]

21 p, 2.8 MB Optimal control of wastewater treatment plants using economic-oriented model predictive dynamic strategies / Revollar, Silvana. (Universidad de Salamanca. Departamento de Informática y Automática) ; Vega, Pastora (Universidad de Salamanca. Departamento de Informática y Automática) ; Vilanova i Arbós, Ramon (Universitat Autònoma de Barcelona. Departament de Telecomunicació i Enginyeria de Sistemes) ; Francisco, Mario (Universidad de Salamanca. Departamento de Informática y Automática)
This paper addresses the implementation of economic-oriented model predictive controllers for the dynamic real-time optimization of the operation of wastewater treatment plants (WWTP). Both the economic-optimizing controller (pure-EMPC) and the economic-oriented tracking controller (Hybrid-EMPC, or HEMPC) formulations are validated in the benchmark simulation model (BSM1) platform that represents the behavior of a characteristic activated sludge process.

9 p, 1.7 MB Overall key performance indicator to optimizing operation of high-pressure homogenizers for a reliable quantification of intracellular components in Pichia pastoris / Garcia-Ortega, Xavier (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental) ; Reyes León, Cecilia (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental) ; Montesinos Seguí, José Luis (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental) ; Valero Barranco, Francisco (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental)
The most commonly used cell disruption procedures may present lack of reproducibility, which introduces significant errors in the quantification of intracellular components. In this work, an approach consisting in the definition of an overall key performance indicator (KPI) was implemented for a lab scale high-pressure homogenizer (HPH) in order to determine the disruption settings that allow the reliable quantification of a wide sort of intracellular components.

21 p, 1.1 MB A general nonconvex multiduality principle / Bonenti, Francesca (Open Capital Partners SGR) ; Martínez Legaz, Juan Enrique (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica) ; Riccardi, Rossana (Università degli Studi di Brescia. Dipartimento di Economia e Management)
We introduce a (possibly infinite) collection of mutually dual nonconvex optimization problems, which share a common optimal value, and give a characterization of their global optimal solutions. As immediate consequences of our general multiduality principle, we obtain Toland-Singer duality theorem as well as an analogous result involving generalized perspective functions. [...]
