Inventor: JULIE KERROD
IPC: C09D5/00
Filed: 2016-10-21
Abstract: REVESTIMENTOS DE REDUÇÃO DE NOX E MÉTODOS PARA REDUZIR NOX COM OS MESMOS. A presente divulgação refere-se a construções e métodos de uso destas para melhorar a redução de NOx no ar. Em particular, foi descoberto que melhorias na redução de NOx são obtidas quando uma formulação de sol de dióxido de titânio fotocatalítica, transparente ou translúcida é fornecida como uma camada sobre uma superfície branca ou superfície semelhante que fornece reflexão alta de luz incidente. A superfície pode ser a superfície de uma estrutura de base subjacente ou uma camada aplicada, tal como uma tinta. A base à qual a(s) camada(s) é(são) aplicada(s) pode ser uma estrutura que é localizada onde a concentração de NOx na atmosfera é particularmente alta, tal como perto de uma estrada ou outras áreas sujeitas a tráfego veicular significante.

IPC: G06Q50/02
Filed: 2017-06-27
Abstract: Em uma modalidade, um método compreende determinar, em dados de rendimento recebidos, uma ou mais passagens, cada passagem incluindo uma pluralidade de observações. Para cada passagem da uma ou mais passagens, uma ou mais derivadas discretas são determinadas e, com base na uma ou mais derivadas discretas, primeiros dados de discrepância são gerados. Os primeiros dados filtrados são gerados por remover os primeiros dados de discrepância a partir dos dados de rendimento. Além disso, para cada observação nos dados de rendimento, uma pluralidade de observações vizinhas mais próximas é determinada, e usada para determinar uma pluralidade de diferenças absolutas nos valores de rendimento. Com base na pluralidade de diferenças absolutas, segundos dados de discrepância são determinados. Os segundos dados filtrados são gerados por remover os segundos dados de discrepância a partir dos primeiros dados filtrados. Usando uma camada de apresentação de um sistema de computador, uma representação gráfica dos segundos dados filtrados é gerada e exibida no sistema de computação.
