U.S. Finds No Evidence of Alien Technology in Flying Objects, but can’t rule it out, either

WASHINGTON — American intelligence officials have found no evidence that aerial phenomena observed by Navy pilots in recent years are alien spacecraft, but they still cannot explain the unusual movements that have mystified scientists and the military. The report determines that a vast majority of more than 120 incidents over the past two decades did not originate from any American military or other advanced US government technology, the officials said. That determination would appear to eliminate the possibility that Navy pilots who reported seeing unexplained aircraft might have encountered programs the government meant to keep secret. But that is about the only conclusive finding in the classified intelligence report, the officials said. And while a forthcoming unclassified version, expected to be released to Congress by June 25, will present few other firm conclusions, senior officials briefed on the intelligence conceded that the very ambiguity of the findings meant the government could not definitively rule out theories that the phenomena observed by military pilots might be alien spacecraft. Americans’ long-running fascination with UFOs has intensified in recent weeks in anticipation of the release of the government report. Former President Barack Obama encouraged the interest when he gave an interview last month about the incidents on “The Late Late Show with James Corden” on CBS. “What is true, and I’m really being serious here,” Mr. Obama said, “is that there is film and records of objects in the skies that we don’t know exactly what they are.’’ The report concedes that much about the observed phenomena remains difficult to explain, including their acceleration, as well as ability to change direction and submerge. One possible explanation — that the phenomena could be weather balloons or other research balloons — does not hold up in all cases, the officials said, because of changes in wind speed at the times of some of the interactions. Many of the more than 120 incidents examined in the report are from Navy personnel, officials said. The report also examined incidents involving foreign militaries over the last two decades. Intelligence officials believe that at least some of the aerial phenomena could have been experimental technology from a rival power, most likely Russia or China. One senior official said without hesitation that U.S. officials knew it was not American technology. He said there was worry among intelligence and military officials that China or Russia could be experimenting with hypersonic technology.

He and other officials spoke about the classified findings in the report on the condition of anonymity.

Um banco tem agências em três regiões do país. Em cada região, trabalha-se com a comercialização de três segmentos: seguros (X), previdência (Y) e consórcios (Z). Cada equação linear que compõe o sistema abaixo representa a capacidade de uma regional produzir valor agregado para o banco, em cada segmento de atuação (lado esquerdo das equações), visando ao alcance das metas de lucro operacional em milhares de reais (lado direito das equações).

  • 2X + 5Y + 4Z = 690 (região Sul)
  • 5X + 2Y + 4Z = 720 (região Sudeste)
  • 3X + 3Y + 2Z = 540 (região Norte)

De acordo com esses dados, verifica-se que a contribuição de um dado segmento que atinge exatamente a meta de sua região é de

Um estudante precisa fazer um trabalho escolar em seu aparelho de telefone celular. Para isso, usará dois aplicativos, A e B, um de cada vez. Ele sabe que a bateria do seu aparelho, estando com carga total, é suficiente para até 4 horas de uso do aplicativo A e sabe também que, com carga total, a bateria é suficiente para até 1 hora e 20 minutos de uso do aplicativo B. Após se certificar de que a bateria de seu aparelho estava com carga total, deu início ao trabalho com o uso do aplicativo A. Depois de algum tempo, ele interrompeu o uso desse aplicativo e, imediatamente, iniciou o uso do aplicativo B, até a bateria descarregar completamente, 3 horas depois do início do trabalho.

Por quanto tempo o estudante usou o aplicativo A?
