Review of the characterization of sodium alginate by intrinsic viscosity measurements: Comparative analysis between conventional and single point methods
(Open Science Publishing, 2014-05)
In the pharmaceutical and food industry, alginate is used in aqueous solutions and excipients as thickener, gelling agent, coagulant and encapsulant. This biopolymer is very important, with many key industrial applications, ...
A hybrid approach combining interior-point and branch-and-bound methods applied to the problem of sugar cane waste
(2017-02-01)
This paper proposes a hybrid approach for solving the multi-objective model related to the minimisation of sugar cane waste collection costs and/or the maximisation of produced energy by this waste, with the aid of strategies ...
Digital signal processing of acoustic emission signals using power spectral density and counts statistic applied to single-point dressing operation
(Inst Engineering Technology-iet, 2017-08-01)
Dressing is an important operation for the grinding process. Its goal is to recondition the wheel tool to re-establish its cutting characteristics, owing to the wear produced after successive passes. Monitoring systems ...
Solving the multiobjective environmental/economic dispatch problem using weighted sum and ε-constraint strategies and a predictor-corrector primal-dual interior point method
(2014)
This paper proposes a technique for solving the multiobjective environmental/economic dispatch problem using the weighted sum and ε-constraint strategies, which transform the problem into a set of single-objective problems. ...
Solving the multiobjective environmental/economic dispatch problem using weighted sum and ε -constraint strategies and a predictor-corrector primal-dual interior point method
(2014-01-01)
This paper proposes a technique for solving the multiobjective environmental/economic dispatch problem using the weighted sum and \varepsilon ε -constraint strategies, which transform the problem into a set of single-objective ...
Evaluation of Quadrature Signal Generation Methods with Reduced Computational Resources for Grid Synchronization of Single-Phase Power Converters through Phase-Locked Loops
Low-cost single-phase grid connected converters require synchronization with the grid voltage to obtain a better response and protection under diverse conditions, such as frequency perturbations and distortion. Phase-locked ...
