Frequency-dependent equivalent linearization method based on strain interval reduction theory
Yantu gongcheng xuebao, 2021 In order to overcome the problem of underestimating the high-frequency Fourier spectrum amplification ratio obtained by the original equivalent linearization method, a frequency-dependent equivalent linearization method considering the effective strain ...

Statistical Properties of the Site-Frequency Spectrum Associated with Λ-Coalescents [PDF]
Genetics, 2013 Abstract Statistical properties of the site-frequency spectrum associated with Λ-coalescents are our objects of study. In particular, we derive recursions for the expected value, variance, and covariance of the spectrum, extending earlier results of Fu (1995) for the classical Kingman coalescent.

The site effect investigation using nonlinear and Iranian seismic code methods in Babol city
Magazine of Civil Engineering, 2022 Site effect is known as one of the important issues in geotechnical earthquake engineering. The site effect can change the characteristics of seismic waves and amplify the vibrations which results in the casualties and financial damages. Nonlinear method

5G Network Coverage Planning and Analysis of the Deployment Challenges
Sensors, 2021 The 5G cellular network is no longer hype. Mobile network operators (MNO) around the world (e.g., Verizon and AT&T in the USA) started deploying 5G networks in mid-frequency bands (i.e., 3–6 GHz) with existing 4G cellular networks. The mid-frequency band

The site-frequency spectrum associated with Ξ-coalescents [PDF]
, 2015 Abstract We give recursions for the expected site-frequency spectrum associated with so-called Xi-coalescents , that is exchangeable coalescents which admit simultaneous multiple mergers of ancestral lineages. Xi-coalescents arise, for example, in

The Genomic Signature of Population Reconnection Following Isolation: From Theory to HIV
G3: Genes, Genomes, Genetics, 2016 Ease of worldwide travel provides increased opportunities for organisms not only to colonize new environments but also to encounter related but diverged populations. Such events of reconnection and secondary contact of previously isolated populations are

A New Method for the Calibration of Site-Related Response Spectra
Advances in Civil Engineering, 2022 The calibration of response spectra is an important issue that needs further research in engineering earthquake resistance. This paper proposes an improved calibration method for site-related response spectra.

Computation of the Likelihood in Biallelic Diffusion Models Using Orthogonal Polynomials
Computation, 2014 In population genetics, parameters describing forces such as mutation, migration and drift are generally inferred from molecular data. Lately, approximate methods based on simulations and summary statistics have been widely applied for such inference ...
