بازیابی میدان جاذبه زمین در مقیاس جهانی به صورت ضرایب هارمونیک کروی با استفاده از مشاهدات ماهواره های اختصاصی ثقل سنجی، به روش های مختلفی صورت می گیرد. برای بازیابی از روش اندازه گیری شتاب و روش انتگرال انرژی استفاده شده است. در این دو روش، محاسبه بردار شتاب و سرعت ماهواره برای بازیابی میدان جاذبه با استفاده از روش های مشتق گیری عددی ضروری می باشد. روش های مشتق گیری نیوتن، اسپیلاین و تیلور و فو...

Introduction: It has been shown that low levels of pigmentation increase susceptibility to noise-induced hearing loss in humans. For this reason, white populations develop more pronounced noise- induced hearing loss in comparison to black populations. Similarly, blue-eyed individuals exhibit greater temporary threshold shift than brown-eyed subjects; still, no strong correlation has been veri...

the stochastic models for ship heave motion in irregular sea waves based on white and colored noises are examined. for this purpose the deterministic model transfers to stochastic models by adding different noise terms in force and then these models are solved analytically and numerically. finally an investigation is undertaken to examine the parameter estimation problem of second order stochas...

Traditionally, stochastic differential equations used in the physical sciences have involved Gaussian white noise. ' In recent times, however, white noise has been replaced by colored noise in a variety of contexts. Laser noise problems and first passage time problems have been shown to necessitate the use of colored noise instead of white noise. Even the mathematical foundations for the theory...

Introduction: The study of noise has always been of interest to occupational health professionals as a harmful physical factor in the workplace. However, the psychological and psychoacoustic aspects of noise in the workplace have been less studied. This study has dealt with different colors of noise and their applications in psychoacoustics. Material and Methods: This review study was conducte...
