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. Investigation on Solar PV generation and design of switched reluctance motor for Smart Agriculture actuation system
ABSTRACT This paper presents standalone solar photovoltaic (PV) powered fed actuation system employing a switched reluctance motor (SRM) particularly used in remote and rural areas. The converter efficiency is achieved by changing ON and OFF state of solar PV drive. An electronic commutation drives SRM drive with achieved by position hall sensor and encoder.

5. Comparação entre mapas de solos obtidos pelos métodos convencional e digital numa área complexa / Comparison between soil maps obtained by conventional and digital methods in complex area
Soil maps are essential for the development of agricultural areas in an economically viable and environmentally friendly manner. So far, Brazil only has soil maps of small scale (1:250,000 to 1:1,000,000), whose use is limited to agricultural and environmental planning at the farm. Despite its importance, in Brazil a few mappings have been carried out by pub

6. Implementação e avaliação de desempenho de estratégias de controle aplicadas em um sistema de armazenamento refrigerado / Implementation and performance evaluation of control strategies applied in a storage system for refrigerated
The cold storage of agricultural products intended to meet a demand for healthier products by markets and consumers. You can also give producers an alternative to extend the time for the marketing of products stored. Cold storage is important for a better conservation of perishable products. Because with the decrease in storage temperature, the metabolic rea

8. Controlador Fuzzy aplicado a um sistema de controle de posição acionador por motores de indução trifásicos / Fuzzy controller applied to a position control system powered by tree-phases induction motors.
This work presents the project of fuzzy controllers for a X-Y coordinate table with two degrees of freedom. Both bases of the table moves horizontally, powered by tree-phases induction motors operated by frequency inverts. For detection position of bases, optical encoders were engaged to the axes of the engines to be obtained the angular displacement. A data

9. Fluxo de carga trifasico com modelagem de incertezas via função de pertinencia sinusoidal / Three-phase power flow with modelling of sinusoidal membership function
A fuzzy direct approach for unbalanced three-phase distribution load flow solutions was developed in this work. The special topological characteristics of distribution networks have been fully utilized to make the direct solution possible. Due to the distinctive solution techniques of the proposed method, the time-consuming LU decomposition and forward/backw
