The Effects of Population Size Histories on Estimates of Selection Coefficients from Time-Series Genetic Data. [PDF]

, 2016
Many approaches have been developed for inferring selection coefficients from time series data while accounting for genetic drift. These approaches have been motivated by the intuition that properly accounting for the population size history can ...

Time history analysis formulation in SCAD FEA software [PDF]

Journal of Measurements in Engineering, 2018
This paper provides the formulation of the problem of forced vibrations of structures, which has the following peculiarities: equations of motion are formulated in absolute coordinates allowing to take into account the asynchronous excitations of the supports, smoothing of the time functions for forced displacements with the help of Hermite polynomials,

The dynamics of proving uncolourability of large random graphs I. Symmetric Colouring Heuristic [PDF]

, 2003
We study the dynamics of a backtracking procedure capable of proving uncolourability of graphs, and calculate its average running time T for sparse random graphs, as a function of the average degree c and the number of vertices N. The analysis is carried

Fast and Reliable Time Delay Estimation of Strong Lens Systems Using Method of Smoothing and Cross-Correlation [PDF]

, 2015
The observable time delays between the multiple images of strong lensing systems with time variable sources can provide us with some valuable information to probe the expansion history of the Universe.

Mass proportional damping in nonlinear time-history analysis [PDF]

Proceedings of the 3rd International Conference on Material, Mechanical and Manufacturing Engineering, 2015
Rayleigh damping is the main form in direct integral method for structural nonlinear dynamic analysis under seismic wave. As stiffness proportional damping usually should be neglected for its significant influence on limit time increment, reasonable mass proportional damping becomes more important in actual engineering.

A Bayesian Account of Quantum Histories

, 2005
We investigate whether quantum history theories can be consistent with Bayesian reasoning and whether such an analysis helps clarify the interpretation of such theories.

Optimization of TFRC loss history initialization [PDF]

, 2007
This letter deals with the initialization of the loss history structure in the TFRC (TCP-Friendly Rate Control) mechanism. This initialization occurs after the detection of the first loss event after every slowstart phase.

Seismic Isolation Performance of Nuclear Power Plant Containment Structures

Buildings
Non-isolated structures have strong destructive effects and poor isolation effects when encountering earthquakes. Setting isolation bearings can prolong the natural vibration period of the structure, reduce the horizontal seismic response of the ...
