2. ERROR BEHAVIOR OF ATOMIC CLOCKS ABOARD GPS SATELLITES
Abstract: The signal transmission and position quality obtained by GNSS positioning directly depends on the time control. The atomic clocks aboard the satellites are responsible for this control. In this research, the satellites clock errors of GPS are studied, using data from the pseudorange, the satellite semi-major axis and the correction parameters of th

5. CONDICIONANTES DAS EMISSÕES DE DIÓXIDO DE CARBONO (CO2) NO BRASIL: EVIDÊNCIAS EMPÍRICAS DE UMA CURVA NO FORMATO DE “N”
RESUMO Este artigo tem como objetivo investigar empiricamente quais os principais condicionantes das emissões de CO2 no Brasil no período 1971-2011. Além disso, este trabalho procura evidências da hipótese da Curva de Kuznets Ambiental (CKA) para o Brasil. As variáveis utilizadas para explicar as emissões de CO2 foram a renda per capita, consumo per c

6. Digital Soil Mapping of Soil Properties in the “Mar de Morros” Environment Using Spectral Data
ABSTRACT Quantification of soil properties is essential for better understanding of the environment and better soil management. The conventional techniques of laboratory analysis are sometimes costly and detrimental to the environment. Thus, development of new techniques for soil analysis that do not generate residues, such as spectroscopy, is increasingly n

7. Application of Response Surface Modeling and Chemometrics Methods for the Determination of Ofloxacin in Human Urine Using Dispersive Liquid-Liquid Microextraction Combined with Spectrofluorimetry
Dispersive liquid-liquid microextraction (DLLME) and spectrofluorimetry, coupled with chemometrics methods, are proposed in this work for the pre-concentration and determination of ofloxacin concentration in spiked human urine. Chloroform and acetonitrile were selected as the extraction and dispersive solvents by the one-variable-at-a-time process. The Box-B

8. ANALYTICAL COMPARISON OF THE PERFORMANCE OF ADAPTIVE MODULATION AND CODING IN WIRELESS NETWORK UNDER RAYLEIGH FADING
Abstract In this paper, an analytic comparison between adaptive modulation (AdM) and adaptive Forward Error Correction (AdFEC) in wireless network telecommunication systems is performed. Through the Gilbert-Elliott model's, the Packet Error Rate (PER) is calculated and both the throughput and the delay, for different modulations and error correction capacity

9. A Hybrid Path Loss Prediction Model based on Artificial Neural Networks using Empirical Models for LTE And LTE-A at 800 MHz and 2600 MHz
Abstract This article presents the analysis of a hybrid, error correction-based, neural network model to predict the path loss for suburban areas at 800 MHz and 2600 MHz, obtained by combining empirical propagation models, ECC-33, Ericsson 9999, Okumura Hata, and 3GPP's TR 36.942, with a feedforward Artificial Neural Network (ANN). The performance of the hyb

10. A correction method for the analytical model in Raman amplifiers systems based on energy conservation assumption
Abstract This paper presents a modification for the already consolidated analytical model that calculates the gain and ripple in multi-pump Raman amplifiers by considering energy conservation. The original analytical model precisely computes the pump-pump interaction to the C- and L-band for a WDM input signal. However, when this method is used to amplify a

11. Determinantes de la oferta de exportación de mango: estudio de caso para el Perú
Mango is one of the most consumed fruit in the world and the most exported by Peru. At present, Peru is the sixth largest exporter in the world. Therefore, the objective of this paper is to analyze the determinants of mango exports by Peru by making more focus to the main target markets, namely the United States and the European Union for the period from 200

12. The impact of OFDI on economic growth countries. An econometric approach using panel data and time-series evidence
The thesis at hand adds to the existing literature by investigating the relationship between economic growth and outward foreign direct investments (OFDI) on a set of 16 emerging countries. Two different econometric techniques are employed: a panel data regression analysis and a time-series causality analysis. Results from the regression analysis indicate a
