The researcher measured the least number of frequency response functions required for the identification of modal parameters, in order to simplify the identification of modal properties of such systems. In this work, the orbital machines are supposed to be a combination of orbital and non-orbital components. Structural Approach specified the identification of dynamic properties only to those ph...

Abstract -Regenerated (FRF curves), synthesis of (FRF) curves there are two main requirement in the form of response model, The first being that of regenerating “Theoretical” curve for the frequency response function actually measured and analysis and the second being that of synthesising the other functions which were not measured,(FRF) that isolates the inherent dynamic properties of a mechan...

Flavonoid-rich fraction (FRF) from Seabuckthorn leaves extract was prepared by acid hydrolysis process. Total flavonoid content of Seabuckthorn leaves extract and FRF estimated as rutin equivalent was found to be 116.98±3.06 and 277.14 ± 6.78 mg/g of extract/FRF respectively. Its major constituents myrcetin, quercetin, kaempferol and isorhamnetin, were determined by reverse phase high performan...

BACKGROUND Syngonanthus arthrotrichus and Syngonanthus bisulcatus, currently known for Comanthera aciphylla (Bong.) L.R.Parra & Giul. and Comanthera bisulcata (Koern.) L.R. Parra & Giul, popularly known in Brazil as "sempre-vivas," are plants from the family Eriocaulaceae. They are found in the states of Minas Gerais and Bahia. The species are known to be rich in flavonoids to which their gastr...

This paper describes a method of utilizing an “F0 Reliability Field” (FRF), which we have proposed in our previous work, for estimating prosodic commands on F0 contour generation model. This FRF is the time-frequency representation of F0 likelihood, and an advantage of FRF is that it is not necessary to consider F0 errors that occur during an automatic F0 determination. Therefore, it is thought...

Road simulation algorithm is the key point of developing a next-generation road simulation testing system. Traditional algorithms need to excite the test system to estimate the FRF matrixes and then iterate again and again until the real response approaches the expect response. The purpose of this paper is to develop a real-time control algorithm of vehicle road simulation test. Road simulation...

To accurately determine the dynamic response of a structure is of relevant interest in many engineering applications. Particularly, it is of paramount importance to determine the Frequency Response Function (FRF) for structures subjected to dynamic loads in order to avoid resonance and fatigue problems that can drastically reduce their useful life. One challenging case is the experimental deter...

OBJECTIVES To document overall, racial, ethnic and intent-specific spatiotemporal trends of firearm-related fatality rates (FRF rates) in the USA. DESIGN Cross-sectional study per year from 2000 to 2010. SETTING USA PARTICIPANTS Aggregate count of all people in the USA from 2000 to 2010. OUTCOME MEASURES Data from the Web-based Injury Statistics Query and Reporting System from 2000 to 201...

Initiation of abscission at the pedicel-fruit zone in the sour cherry (Prunus cerasus L. cv. Montmorency) occurs near the transition of Stage II to Stage III of fruit growth. The preinitiation phase is characterized by a high fruit removal force (FRF) and explants prepared from fruits during this period do not undergo abscission as indexed by a reduction in FRF. Ethylene does not cause a signif...

The time-variant frequency response function (TV-FRF) uniquely characterizes the dynamic behaviour of a linear timevariant (LTV) system. This paper proposes a method for estimating nonparametrically the dynamic part of the TV-FRF from known input, noisy output observations. The arbitrary time-variation of the TV-FRF is modelled by Legendre polynomials. In opposition to existing solutions, the p...
