Membrane-based processes: Optimization of hydrogen separation by minimization of power, membrane area, and cost
(MDPI, 2018-11)
This work deals with the optimization of two-stage membrane systems for H2 separation from off-gases in hydrocarbons processing plants to simultaneously attain high values of both H2 recovery and H2 product purity. First, ...
Análise das vantagens de duas técnicas anestésicas - Venosa e inalatória - Para colecistectomia por videolaparoscopia
(2001-02-19)
Background and Objectives - It is essential to reduce health care costs without impairing the quality of care. Propofol is associated to faster recovery and it is known that post-anesthesia care unit (PACU) costs are high. ...

On Robust Switched Controller Design to Minimize the Guaranteed Cost of Polynomial Fuzzy Systems
(2019-06-01)
This paper presents a robust switched controller design to minimize an upper bound of a quadratic index (guaranteed cost) based on the output and the control input of uncertain nonlinear systems described by polynomial ...
Configuration optimization of series flow double-effect water-lithium bromide absorption refrigeration systems by cost minimization
(Pergamon-Elsevier Science Ltd, 2018-02-15)
An optimal process configuration for double-effect water-lithium bromide absorption refrigeration systems with series flow – where the solution is first passed through the high-temperature generator – is obtained by ...
Output feedback controller design for quadratic cost minimization for linear systems with polytopic uncertainties
(2021-08-15)
This paper proposes a new robust static output feedback control design considering the linear quadratic regulator (LQR) problem based on Linear Matrix Inequalities (LMIs). The output static feedback controller can be used ...
The use of simulation for forecasting the number of docks necessary in an expedition department
(Int Centre Innovation & Industrial Logistics-iciil, 2006-01-01)
The simulation is a very powerful tool to develop more efficient systems, hence it is been widely used with the goal of productivity improvement. Its results, if compared with other methods, are not always optimum; however, ...
Memetic algorithm to minimize costs of activities in rcpsp
(Universidad Nacional de Colombia Sede Medellín, 2012)
The Resource-Constrained Project Scheduling Problem (RCPSP) is a classic and important problem in project management and has got much attention from researchers. In this paper, we consider the case in which the cost of ...
