KINGSLEY, M. C. S. 1979. Fitting the von Bertalanffy growth equation to polar bear age-weight data. Can. J. Zool. 57: 1020-1025. Heavy sea ice in the Canadian Arctic in the winter of 19731974 reduced seal populations; polar bears, preying principally on seals, consequently lost weight. The nature and degree of this weight loss was investigated by examining the parameters of von Bertalanffy grow...

Simulation optimization is an approach that is used to solve problems involving stochastic components. This paper presents a Lexicographic Nelder–Mead (LNM) based simulation optimization (LNM-SO) method to solve multi-criteria simulation optimization problems. The method is designed to be relatively easy-to-implement and be applicable to a wide range of problem domains. To effectively evaluate ...

We calibrate the k-ωSST turbulence model for free surface flows in channel or on slope using machine learning techniques. To model, an experiment is carried out inclined rectangular research chute. In experiment, pressure values flow are measured at different distances from bottom; after transforming data, velocity profile obtained. The calibrated based experimental data Nelder-Mead optimizatio...

Although the brain is not perfectly symmetrical with respect to the mid-sagittal plane, the automatic detection of this plane and of the degree of symmetry is of interest for many anatomical and functional studies. We propose a method for detecting the best symmetry plane in 3D MR brain images. We express this problem as a registration problem and compute a degree of similarity between the imag...

The aim of the present study was to...

Scatter search is an evolutionary method that shares with genetic algorithms, a well-known evolutionary approach, the employment of a combination method that combines the features of two parent vectors to form several offspring. Furthermore, it uses improvement strategies to efficiently produce the local tuning of the solutions. An important aspect concerning scatter search is the trade-off bet...

In the robotic soccer domain, many factors, such as the speed of individual robots, the effectiveness of kicks, and the choice of the appropriate attacking strategy, determine the success of a team. Consequently, soccer robots, and in particular legged ones, require fine tuning of the parameters not only for the vision processes, but also in the implementation of behaviors and basic control act...

Counting cells and following the evolution of the biological layers are important applications in microscopic imagery. In this paper, a microscopic image segmentation method with two-dimensional (2D) exponential entropy based on hybrid microcanonical annealing is proposed. The 2D maximum exponential entropy does not consider only the distribution of the gray-level information but also takes adv...
