Genetic algorithm, MIP and improvement heuristic applied to the MLCLP with backlogging
(2013-08-21)
The present paper solves the multi-level capacitated lot sizing problem with backlogging (MLCLSPB) combining a genetic algorithm with the solution of mixed-integer programming models and the improvement heuristic fix and ...
Size variation in the grapsid crab Aratus pisonii (H. Milne-Edwards, 1837) among populations of different subtropical mangroves
(Kluwer Academic/plenum Publ, 2002-01-01)
Size variation in the adult population of the grapsid crab Aratus pisonii (H. Milne-Edwards, 1837) was studied by comparing median values obtained from six different populations from nearby mangrove areas. The mangrove ...
Reduction of the memory size in the microprogrammed controllers
(2011-12-01)
In the paper the method of reduction of the memory size in the microprogrammed controllers with sharing codes is discussed. The idea is based on the modification of internal modules and connections of the device. Next, the ...
A Hybrid Heuristic Approach to Solve the Multi Level Capacitated Lot Sizing Problem
(Ieee, 2011-01-01)
This paper presents preliminary results found by a hybrid heuristic applied to solve the Multi-Level Capacitated Lot Sizing Problem (MLCLSP). The proposed method combines a multi-population genetic algorithm and fix-and-optimize ...

Size-dependent phase transitions in nanostructured zirconia-scandia solid solutions.
(Laboratório Nacional de Luz Síncrotron.Campinas, 2013-02-26)
Size effects on phase stability and phase transitions in technologically relevant materials have received growing attention. Several works reported that metastable phases can be retained at room temperature in nanomaterials, ...
Influence of Nozzle Type, Speed, and Pressure on Droplet Size and Weed Control from Glyphosate, Dicamba, and Glyphosate Plus Dicamba
(Astm International, 2018-01-01)
Improper or suboptimal application techniques can cause decreased weed control and increased environmental contamination. Droplet size is a key factor in pesticide applications in regard to both drift and efficacy. Droplet ...

(2018-01-01)
Improper or suboptimal application techniques can cause decreased weed control and increased environmental contamination. Droplet size is a key factor in pesticide applications in regard to both drift and efficacy. Droplet ...
Methanol oxidation on PtRu/C electrocatalysts prepared by a microemulsion method
(2007-12-01)
PtRu/C nanocatalysts were prepared by a microemulsion method using different values of water/surfactant molar ratio in order to get different particle sizes. Crystallite sizes and structural properties were determined by ...
The integrated lot sizing and cutting stock problem in a furniture factory
(2013-08-08)
This work studies the integrated lot sizing and cutting stock problem, where the goal is to capture the dependency that exists between two important decisions in the production process, in order to economize raw materials ...
