Abstract: For any linear and time-invariant system, its output is the linear convolution between the variable input sequence and the constant system impulse response. When the input is long and the ...

A new technique developed at the University of Helsinki uses fatty acids, hydrogen peroxide and visible light to dissolve and recover silver from waste, offering a safer alternative to conventional ...

Abstract: Convolution is fundamental in digital signal processing across many applications. Existing works enable N-point linear convolution via N-point right-angle circular convolution (RCC) based on ...

The need to move on from dirty energy sources such as oil is well-established, but though it may not get as much attention, the need to move on from oil-based products is incredibly important as well.

GA, UNITED STATES, May 26, 2025 / EINPresswire.com / -- Researchers have developed a novel method to detect 75 emerging contaminants in sewage sludge and e-waste (WEEE), identifying several chemical ...

A team of European researchers has developed a method to identify hazardous chemicals in two of the most dominant waste types: sewage sludge and electronic waste (WEEE). The new technique, based on ...
