1. A Note on the McCormick Second-Order Constraint Qualification
ABSTRACT The study of optimality conditions and constraint qualification is a key topic in nonlinear optimization. In this work, we present a reformulation of the well-known second-order constraint qualification described by McCormick in 17. This reformulation is based on the use of feasible arcs, but is independent of Lagrange multipliers. Using such a refo

2. Similarity as an extension of symmetry and its application to superrationality
Abstract In this paper we present a concept of similarity in games, on which to ground alternative solution concepts, some of which differ from the classical notions in the field. In order to do this we impose a constraint on players’ beliefs that amounts to a variant of the well-known symmetry principle in classical bargaining theory. We show how this sim

3. DOES ELLIPSIS REPAIR HEAD MOVEMENT CONSTRAINT VIOLATIONS?
Abstract Using English data, I show that Head Movement Constraint violations cannot be repaired by deletion and compare this result with cases of both salvation and non-salvation by ellipsis from previous literature. I then consider two possible sources for this lack of repair. The first is to take the Head Movement Constraint as a derivational constraint, a

4. Synthesis of Sparse Arrays Based On CIGA (Convex Improved Genetic Algorithm)
Abstract In this paper, a novel hybrid algorithm on beam pattern synthesis of sparse arrays is proposed, which aims at minimizing the peak sidelobe level (PSLL). Sparse arrays can provide higher spatial resolution and relatively lower sidelobe than general arrays, but it is necessary to solve the multi-constraint problem of nonconvex nonlinear. Thus, we prop

5. Influence of water level in mine sequencing applied to strategic mining planning
Abstract Developing mine sequencing involves a number of factors and a large amount of information, and consequently the profitability of the project will strongly depend on the production schedule. A mining project may be conditioned to non-optimal sequencing, which may affect the economic results of the project and also lead to an inadequate utilization of

6. Simulação computacional de dispositivos de mistura em câmara de combustão para gases de carbonização
Resumo O carvão vegetal proveniente de florestas plantadas é uma fonte de energia renovável utilizada na siderurgia do Brasil, todavia, em sua produção há liberação do gás de pirólise, que pode ser considerado um gás com baixo poder calorífico inferior. A sustentabilidade da produção de carvão vegetal tem demandado a queima destes gases, poden

7. The electric boat charging problem
Abstract Paper aims This paper studies a new optimization problem called the Electric Boat Charging Problem (EBCP), which is based on the application of electric mobility in a river transport operation problem. Originality This work pioneers the studies of the electric mobility on the river operations, by proposing the EBCP. This problem includes real feat

8. MICROMORPHOLOGICAL OBSERVATION OF EUCALYPTUS SEEDS, MULTIVARIATE STATISTICAL ANALYSES AND MODELING OF THEIR GERMINATION UNDER SALT STRESS AND OSMOTIC CONSTRAINT
ABSTRACT Micromorphological characters including surface, length and width of seeds were recorded for 19 species of Eucalyptus (Myrtaceae) using stereomicroscope to determine the importance of seed morphological characters as an additional tool for identification.With the aim of selecting and valorizing abiotic-stress-tolerant species with landscape and indu

10. Ovicidal and larvicidal potential of Rosmarinus officinalis to control gastrointestinal nematodes of sheep
Resumo As infecções por nematódeos gastrintestinais (ING) constituem a maior limitação à produção de pequenos ruminantes. Na busca do controle desses parasitos, estudos com plantas medicinais têm sido uma importante alternativa. Visto isto, o estudo desenvolvido teve como objetivo avaliar a ação ovicida e larvicida in vitro do óleo essencial de R
