Design optimization of a 3-stage membrane cascade for oligosaccharides purification using mixed integer non-linear programming.
Rizki, Zulhaj; Janssen, Anja E.M.; Hendrix, Eligius María Theodorus; van der Padt, Albert; Boom, Remko M.; Claassen, G.D.H.[et al.] (2020)
Inhomogeneous membrane cascade systems have been utilized to purify fructooligosaccharides (FOS). Such a process allows a different setup at every stage of the cascade. Varying the setup at every stage implies an optimization ... -
Experiments with Active-Set LP Algorithms Allowing Basis Deficiency
Hendrix, Eligius María Theodorus; Guerrero-García, Pablo (IOAP-MDPI, 2022-12-23)
n interesting question for linear programming (LP) algorithms is how to deal with solutions in which the number of nonzero variables is less than the number of rows of the matrix in standard form. An approach is that of ... -
Exploring multiprocessor approaches to time series analysis
Quislant-del-Barrio, Ricardo; Gutiérrez-Carrasco, Eladio Damián; Plata-González, Óscar Guillermo (Elsevier, 2024-02-08)
A time series is a chronologically ordered set of samples of a real-valued variable that can have millions of observations. Time series analysis seeks extracting models in a large variety of domains [31] such as epidemiology, ... -
Floating Point HUB Adder for RISC-V Sargantana Processor
Bandera-Burgueño, Gerardo; Salamero, Javier; Moreto, Miquel; Villalba-Moreno, Julio (Cornell University, 2023)
