Обычные смартфоны помогут следить за состоянием мостов

Крупные инфраструктурные инженерные сооружения, включая мосты и высотные здания, как и все на свете, стареют — и если за этими процессами должным образом не следить, возможны самые тяжелые последствия.

Исследователи из Массачусетского технологического института (MIT) совместно с Военной академией США опубликовали результаты исследований по использованию данных с акселерометров смартфонов для мониторинга целостности мостов. Это позволит владельцам гаджетов принимать посильное участие в выявлении дефектов конструкций, чтобы их можно было своевременно устранять.

Дело в том, что мосты и небоскребы в ответ на возникшую вибрацию «отвечают» колебаниями определенной, присущей только им частоты. Такой эффект можно сравнить с отпечатками пальцев. Однако, чтобы контролировать техническое состояние объекта требуется целый массив специальных дорогостоящих датчиков, которые, в свою очередь, также требуют обслуживания.

Команда исследователей предложила прибегнуть к помощи владельцев смартфонов, ежедневно проезжающих по мосту. Оказывается, что установленные в гаджетах акселерометры могут фиксировать возникающие в сооружении вибрации и сообщать эту информацию аварийным службам, кратно удешевляя процесс мониторинга.

Правда, многие пользователи смартфонов решили отказаться от оказания подобных добровольных услуг, поскольку, участвуя в проекте, они раскрывали свое местоположение.

Во избежание подобных казусов авторам проекта, возможно, лучше задействовать государственные транспортные средства — к примеру, полицейские и почтовые автомобили, а также транспорт логистических компаний.

    shoulder bursitis. Bursa are small fluid crammed sacs that sit between bone and gentle tissue to permit

    front delts, but they’re way more well-liked.
    I might advocate many «safe» variants of overhead urgent; landmine,
    cables, high incline smith machine, bottoms up KB press,
    are just a few examples. Hence, I truly have no real offering of what to do with shoulder pain with reference to pressing variant actions, other than dont make it worse.
