We describe an importance-sampling method for approximating likelihoods of population parameters based on multiple summary statistics. In this first application, we address the demographic history of closely related members of the Drosophila pseudoobscura group. We base the maximum-likelihood estimation of the time since speciation and the effective population sizes of the extant and ancestral ...

In earthquake resistance design of structures, two general concepts have been used. The first is to increase the capacity of the structures to resist the earthquake load effects (mostly horizontal forces) or to increase the dynamic stiffness such as the seismic energy dissipation ability by adding damping systems (both devices and/or structural fuses). The second concept includes seismic isolat...

In contrast to the large amount of ecological information supporting the role of natural selection as a main cause of population divergence and speciation, an understanding of the genomic basis underlying those processes is in its infancy. In this paper, we review the main findings of a long-term research programme that we have been conducting on the ecological genomics of sympatric forms of wh...

In this paper, a semi-active nonlinear artificial intelligence compound controller for marine engines was developed to improve vibration reduction characteristics across wide frequency range. A mathematical model and investigated two-stage isolation systems (Virgin IslandsS) considering vertical, roll, pitch motion. The passive of the magnetorheological damper also integrated with VIS. numerica...

objective: early maladaptive schemas (emss) or fundamental beliefs that underpin stable and trait-like psychological disorders are chronic and relapsing. in, active schemas in dysthymic patients with major depression have been compared with healthy individuals.the purpose of this study was to compare early maladaptive schemas (young, 2003, 1990) in dysthymic patients with major depression and h...

A typical passive mechanical isolation system utilizes a mass-spring-damper as a mechanical filter. Active isolation control systems typically include an electromagnetic transducer to develop the required control forces. In this paper, the technique of sensor-less active shunt control is applied to a mechanical isolation system. An electrical impedance is designed and connected to an electromag...

In this paper, we propose an operator model to detect and identify causes of failure in an emergency, based on which an alarm system in a process can be evaluated and improved. The operator model is a human processor model that includes a perceptual processor, short-term and long-term memories, a cognitive processor, and a motor processor. Knowledge bases for variable information, failure-sympt...
