Lebensohn et al. [1] recently introduced an alternative description of crystal plasticity based on a fast-Fourier transform (FFT) algorithm. The FFT approach solves for the equilibrium stress and strains under the constraint of strain compatibility for systems with periodic microstructures. As currently developed, the FFT model describes plasticity with a set of elasto-viscoplastic constitutive...

In this paper the design of 128/64 point Fast Fourier transform processor (FFT Processor) is proposed to support future generation Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO OFDM) based IEEE 802.11n wireless local area network base band processor. The pipelined mixed radix delay feedback (MRMDF) FFT architecture is proposed to provide a higher throughput rat...

INTRODUCTION Impaired heart rate variability (HRV) is associated with poor outcome in diabetic patients. The present prospective study compared spectral components of HRV obtained by either fast Fourier transform (FFT) or autoregressive (AR) analyses in diabetic patients. METHODS Thirty patients (49+/-12 years; 11 F/19 M; 60% with insulin-dependent type 1 diabetes) underwent 24-h ambulatory e...

This paper is concerned with fast Fourier transform (FFT) approach to option valuation, where the underlying asset price is governed by a regime-switching geometric Brownian motion. An FFT method for the regime-switching model is developed first. Aiming at reducing computational complexity, a near-optimal FFT scheme is proposed when the modulating Markov chain has a large state space. To test t...

Background: Multisystemic Therapy (MST) and Functional Family (FFT) are evidence-based Blueprint programs shown to be effective towards youth problem behaviors. Purpose: The present study aimed investigate treatment outcomes following MST FFT among Norwegian youths with serious behavior problems. Research design: Routine Outcome Monitoring (ROM) data of the Youth Level Service/Case Management I...

Fast Fourier Transform (FFT) plays an important role in the field of digital signal processing. High performance FFT processors are widely used in different application, such as speech processing, image processing, and communication system. In this paper, we proposed a novel register array based low power FFT processor for Mel Frequency Cepstral Coefficient (MFCC). Compared with [9-12], this no...

The discovery of the fast Fourier transform (FFT) algorithm and the subsequent development of algorithmic and numerical methods based on it have had an enormous impact on the ability of computers to process digital representations of signals, or functions. At first, the FFT was regarded as entirely new. However, attention and wide publicity led to an unfolding of its pre-electronic computer his...

This evaluation compared the efficiency and effectiveness of Functional Family Therapy-Child Welfare (FFT-CW®, n=1625) to Usual Care (UC: n=2250) in reducing child maltreatment. FFT-CW® is a continuum of care model based on the family's risk status. In a child welfare setting, families received either UC or FFT-CW® in a quasi-experimental, stepped wedge design across all five boroughs of New Yo...
