This paper presents a study of the Modified Discrete Cosine Transform (MDCT) and its implications for audio coding and error concealment from the perspective of Fourier frequency analysis. A relationship between the MDCT and DFT via Shifted Discrete Fourier Transform (SDFT) is established, which provides a possible fast implementation of MDCT employing an FFT routine. The concept of Time Domain...

This article presents two networks that improve upon the behavior and performance of previously published sliding discrete Fourier transform (SDFT) algorithms. The proposed are structurally simple, computationally efficient, guaranteed stable used for real-time spectrum analysis. first network computes one spectral output sample, equal to a single-bin an N-point DFT, each input signal sample. s...

Background A common cause of lameness in horses is tenovaginitis the digital flexor tendon sheath (DFTS). Ultrasound and contrast tenography have become frequently used diagnostic tools for abnormalities DFTS, but are considered insufficiently accurate describing specific lesions. Objectives To determine sensitivity specificity computed tomographic (CTT) 3 Tesla magnetic resonance imaging (MRI)...

twelve left camel forelimbs were collected, and ultrasonography was performed at five different levels around the metacarpal region. limbs were then cut in the transverse plane at levels corresponding to the ultrasound images. transverse and sagittal plane images were taken at each of the five levels, keeping all ultrasound imaging factors constant. echogenicity, diameter, width and cross secti...

Objective-To determine the effect of ultrasound therapy on hydroxyproline (HP) content in superficial digital flexor tendon (SDFT) in horses.Design - Experimental in vivo study.Animals - Eight adult castrated horses.Procedure- The mediocaudal surface of right metatarsal bone in was exposed and after complete separation of SDFT, it was splitted (striking 15 times) in full thickness in longitudin...
