A Fully-Electric Performance Motorcycle
Why do many people hesitate to go electric? The main reason is range. What exactly is range? Just like mileage is distance travelled per litre of fuel, range of an electric vehicle (EV) is total distance driven on one full charge of the battery pack. And just like mileage of an internal combustion engine (ICE), range of an EV is also affected by circumstantial and environmental changes, such as city versus highway, road conditions, age of vehicle, operating temperatures, average weight riding and so on
AI-Based Intelligent Baggage Scanner System
With millions of people travelling during the holidays, it is a busy time for any airport and/or metro station. Long lines, delays and pushing carry-ons into a scanner are common things people encounter. Currently, information is sent to the computer it is connected to, which identifies the objects using identification algorithms. Algorithms calculate z effective number (number of protons in a nucleus) and mass density of objects in the bag to construct an image showing the position of objects and their density. That is how existing technology differentiates flour from cocaine, talcum powder from explosive ones and regular plastic from a bomb casing
