Pulse period of earthquake records has been known as a key parameter in seismology and earthquake engineering. This paper presents a detailed characterization of this parameter for a special class of earthquake records called pulse-like ground motions. This type of motions often resulting from directivity effects is characterized by a strong pulse in the velocity time history of motion, in norm...

The growth of actin filament networks is a fundamental biological process that drives a variety of cellular and intracellular motions. During motility, eukaryotic cells and intracellular pathogens are propelled by actin networks organized by nucleation-promoting factors that trigger the formation of nascent filaments off the side of existing filaments in the network. A Brownian ratchet (BR) mec...

Previous research into running has demonstrated consistent patterns in pelvic, lumbar and thoracic motions between different human runners. However, to date, there has been limited attempt to explain why observed coordination patterns emerge and how they may relate to centre of mass (CoM) motion. In this study, kinematic data were collected from the thorax, lumbar spine, pelvis and lower limbs ...

When simulating large crowds, it is inevitable that the models and motions of many virtual characters will be cloned. However, the perceptual impact of this trade-off has never been studied. In this paper, we consider the ways in which an impression of variety can be created and the perceptual consequences of certain design choices. In a series of experime ts designed to test people’s perceptio...

کنترل دقیق پارامترهای دخیل در سالن های پرورش قارچ می تواند یکی ازعوامل موثر در کاهش مصرف انرژی و یا حتی افزایش کمی و کیفی محصول باشد. در این پژوهش با استفاده از کنترل فازی و کنترل on/off مدلی برای کنترل دمای کمپوست، رطوبت نسبی داخل سالن و غلظت دی اکسیدکربن همچنین با استفاده از نرم افزار شبیه ساز متلب مدل سالن و تجهیزات کنترلی مانند هواساز، طراحی شد. برای طراحی مدل کنترلی یک سری داده برداری اولی...
