It seemed that the city danced to the beat of the generator drum, always one or two roaring somewhere, so that in the end you barely heard them. Maybe the silence of bare feet on sand would be more disturbing. He leant on the marble bar and sipped his drink. It was the perfect mix...
Maybe he needed the insurance money to pay for an operation, or maybe if he had been behind the wheel he would have been in a big pile-up.” My head was spinning. “You’re saying you give them something, some kind of useless potion made of stuff you picked up in an alley, and ...
The problem of remaining useful life estimation (RULE) of hollow worn railway vehicle wheels in terms of remaining mileage via wheel tread depth estimation using on-board vibration signals from a single accelerometer on the bogie frame is presently investigated. This is achieved based on the introdu...
In view of our setup in Figure 2, we model the human–bicycle mechanics by a simple inverted pendulum about the contact point of the bicycle wheel. Based on the time series statistics in Table 1, we also assume that the roll angle 𝜃θ about the equilibrium is sufficiently small; the ...
When the external wind speed changes, the HSVA harvester can enhance the power generation efficiency of the generator to decrease the power error by changing its own mechanical structure to match wind speed. In the random breeze environment, experimental results show that the maximum energy ...
