Allocation of measurement devices is a necessity of distribution system which is an application of state estimation. In this paper, the problem of active and reactive measurement devices is modeling using a multi-objective method. The objectives of the problem are to minimize the use of measurement devices, increase in state estimation output, improve the state estimation quality and reduce cos...
Thermocline layer have remarkable effects on acoustic propagation in Persian Gulf environment. So far, no comprehensive research has been conducted to explore thermocline layer, especially its characteristics including top, thickness, and thermal gradient of thermocline in Persian Gulf. Besides, effects of thermocline on underwater acoustic propagation including transmission loss and sound chan...
Analyzing variability of measured runoff and soil loss data under different condition of measurement system, are critical for advancing erosion science, evaluating hydrologic models, and designing erosion experiments. For this purpose, the current study aimed to evaluate how runoff and soil loss are influenced by hillslope direction and length in Sangane arid rangeland, Razavi Khorasan Provi...
بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Objectives: Real ear measurement plays a critical role in children’s hearing aid fitting. This study aimed to evaluate the conformity of measured and predicted real-ear aided response (REAR) of prescribed formula desired sensation level (DSL) v5 Pediatric in children aged 4 to 7 years. Since there is limited information about the effect of the degree of hearing loss (DOHL), ethnicity, gender, a...
