Digital Twin
Digital Twin: Above is an image from the digital twin (DT) of BMW’s factory in Regensburg, Bavaria, created in NVIDIA’s Omniverse. There are two versions of a BMW factory in the medieval town of Regensburg, Germany. One is a physical plant that cranks out thousands of cars a year. The other is a virtual 3-D replica, accessed by screen or VR headset, in which every surface and every bit of machinery looks exactly the same as in real life. Soon, whatever is happening in the physical factory will be reflected inside the virtual one in real time: frames being dipped in paint; doors being sealed onto hinges; avatars of workers carrying machinery to its next destination. The latter factory is an example of a “digital twin”: an exact digital re-creation of an object or environment. The concept might at first seem like sci-fi babble or even a frivolous experiment: Why […]
THE CYCLONE
THE CYCLONE: _ _ Prologue: I am not fond of weather analysis. Many times I inadvertently watch weather forecast on TV which I find quite boring. Nonetheless, after discussing earthquakes and tsunamis, I felt that I should discuss adverse weather events which also affect our lives. A storm is any disturbed state of atmosphere, and strongly implying severe weather; marked by strong wind, thunder, lightning and heavy precipitation (rain, ice etc). Storms are created when a center of low pressure develops, with a system of high pressure surrounding it. This combination of opposing forces can create winds and result in the formation of storm clouds. Storms generally lead to significant negative impacts to lives and property. The vertical wind shear in thunderstorm can cause airplane crashes. Severe weather is also responsible for plenty of helicopter crashes, and delay launch of space shuttles. There are various types of storms including tropical […]
