Captação de dados da Internet para a criação de uma simulação do Campeonato Brasileiro de Futebol com R
Este artigo explora a utilização de dados obtidos da internet para construir uma simulação do Campeonato Brasileiro de Futebol. O processo envolve a extração de informações, como a força do elenco e históricos de jogos do campeonato. A simulação é realizada por meio de um código em R, que incorpora métricas como força do elenco, fator mandante, fator visitante, confronto direto e saldo de gols para determinar os resultados dos jogos. As métricas são aplicados à simulação dos 760 jogos do campeonato, culminando na criação de uma tabela com a classificação final, apresentada de forma intuitiva por meio do PowerBI.This article explores the use of data obtained from the internet to build a simulation of the Brazilian Football Championship. The process involves extracting information such as team strength and historical match data from the championship. The simulation is conducted through an R code, incorporating metrics such as team strength, home factor, away factor, direct confrontation, and goal difference to determine match outcomes. These metrics are applied to simulate the 760 championship matches, resulting in the creation of a table with the final standings, intuitively presented through PowerBI
Impact of injection on reservoir performance in the NCPA steam field at The Geysers
A managed injection program implemented by the NCPA in The Southeast Geysers reservoir continues to positively impact reservoir performance. Injection effects are determined by the application of geochemical and geophysical techniques to track the movement of injectate. This information, when integrated with reservoir pressure, flowrate, and thermodynamic data, is used to quantify the overall performance and efficiency of the injection program. Data analysis indicates that injected water is boiling near the injection wells, without deeper migration, and is recovered as superheated steam from nearby production wells. Injection derived steam (IDS) currently accounts for 25 to 35 percent of total production in the NCPA steamfield. Most importantly, 80 to 100% of the injectate is flashing and being recovered as steam. The amount of IDS has increased since 1988 due to both a change in injection strategy and a drying out of the reservoir. However, significant areas of the reservoir still remain relatively unaffected by injection because of the limited amount of injectate presently available. That the reservoir has been positively impacted in the injection areas is evidenced by a decrease in the rate of pressure decline from 1989 through 1992. Correspondingly, there has been a reduction in the rate of steam flow decline in the areas' production wells. Conversely, little evidence of reservoir cooling or thermal breakthrough is shown even in areas where IDS accounts for 80 percent or more of production. Finally, since injection water is a relatively low-gas source of steam, noncondensible gas concentrations have been reduced in some steam wells located within the injection dominated areas
Unmanned Aerial Systems in Occupational Hygiene—Learning from Allied Disciplines
Unmanned Aerial System (UAS) technologies are rapidly developing, lowering cost, and technology barriers for their use in numerous applications. This review and commentary summarizes relevant literature in allied fields and evaluates potential application and utility of UAS technology in the discipline of occupational hygiene. Disciplines closely related to occupational hygiene are moving to investigate potential uses—and in some cases—already employing this technology for research or commercial purposes. The literature was reviewed to formulate a cross-sectional picture of how UAS technology is being used in these closely allied disciplines which could inform or guide potential use in occupational hygiene. Discussed are UAS applications in environmental monitoring, emergency response, epidemiology, safety, and process optimization. A rapidly developing state of the art indicates that there is potential utility for this technology in occupational hygiene. Benefits may include cost savings, time savings, and averting hazardous environments via remote sensing. The occupational hygiene community can look to allied fields to garner lessons and possible applications to their own practice.Abstract © 2015 Oxford University Pres
