Packing Circles Within Circular Containers: A New Heuristic Algorithm For The Balance Constraints Case

In this work we propose a heuristic algorithm for the layout optimization for disks installed in a rotating circular container. This is a unequal circle packing problem with additional balance constraints. It proved to be an NP-hard problem, which justifies heuristics methods for its resolution in larger instances. The main feature of our heuristic is based on the selection of the next circle to be placed inside the container according to the position of the system's center of mass. Our approach has been tested on a series of instances up to 55 circles and compared with the literature. Computational results show good performance in terms of solution quality and computational time for the proposed algorithm.36227930

The multi-vehicle covering tour problem: building routes for urban patrolling

In this paper we study a particular aspect of the urban community policing: routine patrol route planning. We seek routes that guarantee visibility, as this has a sizable impact on the community perceived safety, allowing quick emergency responses and providing surveillance of selected sites (e.g., hospitals, schools). The planning is restricted to the availability of vehicles and strives to achieve balanced routes. We study an adaptation of the model for the multi-vehicle covering tour problem, in which a set of locations must be visited, whereas another subset must be close enough to the planned routes. It constitutes an NP-complete integer programming problem. Suboptimal solutions are obtained with several heuristics, some adapted from the literature and others developed by us. We solve some adapted instances from TSPLIB and an instance with real data, the former being compared with results from literature, and latter being compared with empirical data.Comment: 28 pages, 8 figures, 7 tables, Brazilian Operations Research Society; Printed version ISSN 0101-7438 / Online version ISSN 1678-514

Pareto optimality conditions and duality for vector quadratic fractional optimization problems

One of the most important optimality conditions to aid in solving a vector optimization problem is the first-order necessary optimality condition that generalizes the Karush-Kuhn-Tucker condition. However, to obtain the sufficient optimality conditions, it is necessary to impose additional assumptions on the objective functions and on the constraint set. The present work is concerned with the constrained vector quadratic fractional optimization problem. It shows that sufficient Pareto optimality conditions and the main duality theorems can be established without the assumption of generalized convexity in the objective functions, by considering some assumptions on a linear combination of Hessian matrices instead. The main aspect of this contribution is the development of Pareto optimality conditions based on a similar second-order sufficient condition for problems with convex constraints, without convexity assumptions on the objective functions. These conditions might be useful to determine termination criteria in the development of algorithms.Coordenação de aperfeiçoamento de pessoal de nivel superior (Brasil)Ministerio de Ciencia y TecnologíaConselho Nacional de Desenvolvimento Científico e Tecnológico (Brasil)Fundação de Amparo à Pesquisa do Estado de São Paul

AGRICULTURA FAMILIAR E COOPERATIVISMO

A agricultura familiar vem historicamente relegada à marginalização por parte do Estado, ou seja, até a virada do século deu quase nenhuma/pouquíssima atenção a esse setor produtivo brasileiro, porém com o avanço de governos progressistas ao comando do Estado, passou a ter políticas públicas direcionadas à manutenção dos trabalhadores no campo e na zona rural, através de linhas de créditos e de financiamento das produções. Outro fator que minimizou o êxodo rural foi às cooperativas que por décadas trabalharam aliadas a esses agricultores na manutenção, no fornecimento de tecnologia e formação técnica qualificada, para minimizar os estragos causados pelo avanço do capitalismo e do agronegócio com os latifúndios de commodities. Diante disso, o presente artigo pretende desenvolver um panorama sobre a agricultura familiar no Brasil e sobre o cooperativismo rural, analisando as dificuldades e possibilidades de uma agricultura familiar comprometida com a sustentabilidade e com o meio ambiente. O presente artigo está disposto em um capítulo com dois subtópicos, no primeiro subtópico é construído um panorama histórico sobre a agricultura familiar, analisando as condições dos agricultores se manterem no campo e das novas gerações terem possibilidades de educação, lazer e condições de trabalho e renda a partir da agricultura familiar. O segundo subtópico analisa o papel das cooperativas nesse processo e quais entraves e possibilidades podem ser vistas para a melhoria de renda e de condições sociais para a agricultura familiar. Por fim, as considerações finais são um apanhado das possibilidades e dificuldades que a agricultura familiar, consequentemente os agricultores familiares enfrentam; ainda é abordada nessa parte conclusiva a resistência vivenciada perante o agronegócio, e avaliam-se as possibilidades e a importância da agricultura familiar para o Brasil

Association between seroprevalence of IgG anti-Toxoplasma gondii and risk factors for infection among pregnant women in Climério de Oliveira Maternity, Salvador, Bahia, Brazil

Maternal Toxoplasma gondii (T. gondii) infection can lead to spontaneous abortion, fetal malformation, and numerous sequelae in the newborn, including visual and hearing impairment. T. gondii serology was determined in pregnant women and their newborns who were referred to Climério de Oliveira Maternity, Federal University of Bahia, and the possible associations with the risk factors for maternal infection were investigated. This cross-sectional study was conducted from January to December 2014 and included 712 pregnant women, aged 15 to 49 years, and 235 newborns. Seroprevalence was determined by the detection of T. gondii-specific immunoglobulin (Ig) M (IgM) and IgG antibodies using enzyme-linked immunoassay. In addition, mothers completed a questionnaire that focused on socioeconomic aspects, and survey data were tabulated using the SPSS statistical software program (version 21.0 for Windows). The seroprevalence rate for specific IgG antibodies was 51% (362) among mothers and 93% (219) among neonates. All the mothers and their newborns were negative for specific-IgM antibodies. Higher age group and lower maternal education were the only risk factors statistically associated with the presence of specific IgG. In summary, high levels of specific IgG antibodies were observed in pregnant women. The knowledge of risk factors for toxoplasmosis can help in the orientation of newly pregnant women
