1. Power Allocation in PON-OCDMA with Improved Chaos Particle Swarm Optimization
Abstract In this work, it is investigated an improved chaos particle swarm optimization (IC-PSO) scheme to refine the quality of the algorithm solutions regarding to solve the optimal power allocation in next generation passive optical networks (NG-PON)s. The proposed IC-PSO scheme utilizes the Beta distribution instead of uniform distribution of the traditi

2. Processo de formação de estratégias de marketing na hotelaria paraibana
This paper aims to analyze the marketing strategies formation process in hotels, located in the city of João Pessoa. The strategy making process seeks to understand how they are formulated within the organizations, as well as changes occur throughout this process. To understand the strategies formation process, was used as a methodological procedure qualita

3. Modelo matemático para avaliação de desempenho de sistemas de irrigação.
The irrigation performance of any irrigation systems is highly facilitated when using a fitted model to represent the measured data. Several statistical distribution models, such as uniform, normal, lognormal, specialized power, beta, and gamma, have been used to fit applied water from irrigation, as na aid to evaluate the irrigation performance. However, th

4. Estudo de expansões assintóticas, avaliação numérica de momentos das distribuições beta generalizadas, aplicações em modelos de regressão e análise discriminante
Inicialmente, realiza-se uma revisão literária sobre as expansões assintóticas de Daniels, Edgeworth, Lugannani-Rice e Cordeiro-Ferrari. Mediante uso da expansão de Cordeiro- Ferrari, torna-se possível realizar um estudo correspondente a aproximação da distribuição gama G(m;f ) em função da distribuição exponencial com média a. E, ainda, numa

5. The influence of bromazepam on cortical power distribution
O EEG tem sido amplamente empregado na avaliação de mudanças eletrofisiológicas induzidas por medicações distintas.A sensibilidade desta técnica em detectar alterações produzidas por uma substância pode ser aprimorada por métodos de análise quantitativa (EEGq). O presente estudo teve por objetivo investigar os efeitos modulatórios do bromazepam

6. Avaliação de betas por fundamentos: uma análise de empresas do setor elétrico na América Latina / Estimating betas from fundamentals: an analysis of Latin American electric sector companies
It is necessary to calculate the cost of equity which effectively shows the intrinsic business risk. The most used method to estimate the cost of equity encompasses the use of average of traded stocks betas. Although, the number of electrical power companies with different activities: generation, distribution, transmission and trading, and the percentage tha

7. Predição de fator de simultaneidade através de modelos de regressão para proporções contínuas / Prediction of simultaneity factor using regression models for continuous proportions.
The simultaneity factor is fundamental in planning gas distribution networks. It is a multiplicator between 0 and 1 that adjusts the theoretical total consumption of a number of devices to realistic conditions. In 2005, the Instituto de Pesquisas Tecnológicas (IPT) and the Companhia de Gás de São Paulo (COMGÁS) performed a study in which the simultaneity

8. Relativistic jets and accretion phenomena associated with galactic and extragalactic black holes
More than a dozen binary star systems hosting stellar-mass black holes have been discovered in our galaxy. Some of them eject collimated relativistic jets with apparent velocities larger than the light speed. These objects have been named microquasars thanks to their similarity with the distant quasars or active nuclei of galaxies that host supermassive blac

9. Power-Laws in Interferon-B mRNA Distribution in Virus-Infected Dendritic Cells
Interferon-beta (IFNB1) mRNA shows very large cell-to-cell variability in primary human dendritic cells infected by Newcastle disease virus, with copy numbers varying from a few to several thousands. Analysis of data from the direct measurement of the expression of this gene in its natural chromatin environment in primary human cells shows that the distribut

10. Power spectrum analysis of EEG at diagnosis and follow up of patients with solvent induced chronic toxic encephalopathy.
Electroencephalographic changes have been studied in a group of 32 men aged 30-65 (mean 49) with diagnosed chronic toxic encephalopathy. The group had been carefully scrutinised for other possible causes of brain dysfunction and the diagnosis was based on neuraesthenic symptoms and pathological psychometric performance. The EEGs were recorded from four areas

11. Resolution of hypervariable regions in T-cell receptor beta chains by a modified Wu-Kabat index of amino acid diversity.
The Wu-Kabat variability coefficient is a well-established descriptor of the susceptibility of an amino acid position to evolutionary replacements. It conveniently highlights stretches of accentuated amino acid variation that, for example, in an antibody molecule account for most of the antigen contacts (complementarity-determining regions). Diverse opinion

12. Effect of obesity on vancomycin pharmacokinetic parameters as determined by using a Bayesian forecasting technique.
Few data exist concerning the effect of obesity on the pharmacokinetic parameters of vancomycin. The purpose of this investigation was to assess the effect of obesity on vancomycin pharmacokinetic parameters in 95 nonobese and 135 obese adult patients (age range, 18 to 92 years) receiving vancomycin. All subjects had normal renal function as defined by a cre
