Bruker Corporation today announced the launch of the VERTEX NEO Ultra, its most advanced and versatile benchtop vacuum ...
Over at Quanta Magazine [Shalma Wegsman] asks What Is the Fourier Transform? [Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation ...
Abstract: Energy distribution over fractional Fourier transform (FRFT) can represent more characters of face images in different angles, which can improve recognition accuracy. This paper presents a ...
On Thursday French large language model (LLM) developer Mistral launched a new API for developers who handle complex PDF documents. Mistral OCR is an optical character recognition (OCR) API that can ...
ABSTRACT: The exponential transform or modified Fourier transform is an integral transform where the Kernel function is K a ( ξ,t )= a −iξt , and a∈] 1,+∞ [ . This is a general case of the Fourier ...
Abstract: The fractional Fourier transform (FRFT) parametrically generalizes the Fourier transform (FT) by a transform order, representing signals in intermediate time-frequency domains. The FRFT has ...
The sampling process of a signal is of an ideal type as it extends from −∞ to +∞ on the time axis, hence the infinite number of instants t n. This destroys the possibility of using an electronic ...
