1. Assessment of Total Attenuation and Adaptive Scheme for Quality of Service Enhancement in Tropical Weather for Satellite Networks and 5G Applications in Nigeria
Abstract The dynamic weather condition is a major concern for optimum channel utilization in recent times, especially at higher frequencies with larger bandwidth for 5G applications. Over the years, rain-induced attenuation among the hydrometeors has been linked as the major cause of signal impairment especially at the frequency, f ≥ 10 GHz. However, when

2. Simplified Methodology for Temperature Calculation of Operation and Photovoltaic Modules Yield in Non-Standardized Environmental Conditions
ABSTRACT This work proposes a simplified methodology to obtain the needed data to determine and investigate the variation of photovoltaic modules performance under non-standardized environmental conditions - Standard Test Conditions and Nominal Operating Cell Temperature. This methodology uses a previously developed mathematical model in association with env

4. Zoneamento agroclimático para a cultura do pinus no Estado do Espírito Santo
The objective of this work is to make an agroclimatic zoning for the species Pinus elliottii var. Elliottii, Pinus caribaea var. hondurensis, Pinus taeda and Pinus oocarpa for the State of Espírito Santo, identifying areas with climatic aptitude for implantation of stand of production. It was used eteorological data of the period of 1977 to 2006, from eight

5. Study of the winds in Rio Grande do Sul and simulation for an extratropical cyclone using MM5 Model / Estudo dos ventos no Rio Grande do Sul e simulação para um ciclone extratropical usando o Modelo MM5
Neste trabalho é mostrado o estudo sobre os ventos no Rio Grande do Sul, durante o período 2000-2007, para identificar onde e quando os ventos foram mais intensos no Estado. Foram utilizados dados de velocidades obtidos a 10m de altura, nos três horários de observação (00, 12 e 18UTC) de 15 estações meteorológicas, bem distribuídas no Estado. A ide

6. Simulação do clima do último máximo glacial: um experimento com um modelo estatístico - dinâmico / Simulation of the last glacial maximum climate: a experiment with a statistical-dynamical model
A statistical - dynamical zonally averaged model of primitive equations was used to evaluate the capacity of the model in simulating the zonally averaged climate of the Last Glacial Maximum (LGM), studying the relative importance of the climate forcing in the LGM climate and to diagnosis the monsoon circulation in the LGM. The simulation of the LGM resulted

8. Construção de um instrumento para a medida e estudo do campo elétrico da atmosfera / Fabrication of an instrument for measuring and the study of the atmospheric electric field.
An equipment was constructed for utilizing with the aim at performing the measurement of vertical atmospheric electric field next to the earth surface in Pelotas town, in fair-weather conditions (sky free of clouds) and it uses as a sensor a field mill of the rotating dipole type in stainless steel with 30 centimeter length. This aerial is set in motion by a

9. Impacto de um esquema objetivo de análise nas simulações de eventos meteorológicos num modelo regional. / Impact of an analysis objective scheme to simulate meteorological events regional model.
An objective scheme of data analysis was implemented in a limited area model for numerical forecast. It is composed of two parts: initialization and continuous data assimilation. The hydrostatic numerical model used was developed by the Japan Meteorology Agency. It is written in flux form using s-p vertical coordinates. The initialization procedure combines

11. Métodos de geoprocessamento na avaliação da susceptibilidade do cerrado ao fogo.
Anualmente, o Cerrado é queimado em 20 a 30% de sua área durante a estação seca, principalmente devido a causas antrópicas. Três fatores simultâneos são necessários para que as queimadas ocorram: condições meteorológicas propícias; disponibilidade de combustível vegetal; existência de fonte de ignição. Este trabalho estudou a susceptibilidad

12. The fog formation conditions in Pelotas / Condições para formação de nevoeiro em Pelotas
The fog formation conditions at Pelotas city, during January 1995 to April 1996 period, have been analyzed using conventional synoptic data, adiabatic diagrams, GOES-8 satellites imageries and hourly superface data ( Temperature, Relative Humidity, Wind Velocity and Atmospheric Pressure). These conditions were classificated using the synoptics situations ana
