1. MIMO-PLC Communications in an Experimental Medium Voltage Network: Measurement and Analysis
Abstract This paper presents measurements at a mock-up medium voltage network to verify the feasibility of Broadband Power Line Communication (BPLC). We use the data extracted within the frequency range 2 − 30 MHz to characterize a MIMO PLC network using different phase combinations, defining the best and worst use case scenarios. The empirical data shows

2. A SIR Model with Spatially Distributed Multiple Populations Interactions for Disease Dissemination
ABSTRACT In this contribution we analyze a discretized SIR (Susceptible, Infectious, and Removed) compartmental model, to investigate the role of individual interactions in the spread of diseases. The compartments S i,j , I i , j and R i , j ( i , j , = 1 , 2 , . . . , n ) are spatially distributed in a two-dimensional n × n network. We assume tha

3. Multi-Step-Ahead Spectrum Prediction for Cognitive Radio in Fading Scenarios
Abstract This paper analyzes multi-step-ahead spectrum prediction for Cognitive Radio (CR) systems using several future states. A slot-based scenario is used, and prediction is based on the Support Vector Machine (SVM) algorithm. The aim is to determine whether multi-step-ahead spectrum prediction has gains in terms of reduced channel-switching and increased

4. Editorial Comment: Penile cancer information on the internet: a needle in a haystack
Abstract A good wireless network design depends on technical and financial viability and a number of other criteria that must be met. Following the emergence of new technologies and services, such as 5G transmission and the reuse of frequencies, new work is being carried out to ensure a better design for a particular area. This study examines a discrete radi

6. Relação entre saneamento básico e saúde pública em Bissau, Guiné-Bissau
Resumo Este artigo avalia a relação de custos entre a saúde pública e a implementação do saneamento básico na capital da Guiné-Bissau. Analisaram-se seis cenários, incluindo três opções para o sistema de esgotamento sanitário (sistema coletivo com rede coletora e estação elevatória de esgoto, sistema simplificado individual por latrina e sist

7. Analysis of the long-term effects of groundwater extraction on the water balance in part of the Urucuia Aquifer System in Bahia - Brazil
Resumo Em regiões agrícolas onde há insuficiência de chuva para o cultivo, entender a dinâmica das águas, superficiais e subterrâneas, é fundamental para avaliar o impacto do crescente bombeio de poços sobre o balanço hídrico. O Oeste do estado da Bahia-Brasil, maior área de agronegócio do estado, experimenta uma progressiva ocupação a partir

9. OUTLIER=GROSS ERROR? DO ONLY GROSS ERRORS CAUSE OUTLIERS IN GEODETIC NETWORKS? ADDRESSING THESE AND OTHER QUESTIONS
Abstract This article has theoretically discussed some points regarding outliers caused by errors in geodetic observations (see consideration made). Comments have also been made on the usual 3σ-rule to identify outliers and its common approachs in the simulation of outliers in geodetic networks. Three simulated experiments have been conducted to verify the

10. Channel Characteristics for Fixed and Portable DTV Reception in a Single Frequency Network
Abstract This paper presents the propagation channel characteristics of a digital TV single-frequency network (SFN) obtained by carrying out field measurements using two synchronized transmitters. The measurements are performed at 31 reception points using both a directive reception antenna, which is typical of fixed reception scenarios, and an omnidirection
