DEVICE DEVELOPMENT FOR DETERMINING THE EQUIVALENT HARMFUL ELECTRICALMAGNETIC RADIATION

Design an Equivalent Left Ventricular Assist Device for Medical Equipment Labs

LVAD is a mechanical pump supporting a weak heart function and blood flow. Sometimes, the heart may not recover fast enough to take over the pumping action immediately after surgery, in such patients a temporary support device has been employed to maintain the pumping action until the patient’s own heart recovers. This device can be considered as a temporary alternative before the process of ar...

Determining attenuation of impulse noise with an electrical equivalent of a hearing protection device.

Determining the effectiveness of impulse noise attenuation with hearing protection devices (HPDs) is an important part of their selection. Measuring impulse noise parameters under an HPD would involve exposing subjects to impulses with a high peak sound pressure level. This paper presents a computational method of determining impulse noise parameters under the cups of earmuffs. Calculations are...

Determining The Degree Of Development Of The OIC State Members, For Establishing A Common Market

Presenting an Optimal Model for Determining the Potential Areas of Industrial Development in Alborz Province

In this study, three criteria and 10 sub-criteria and 18 indicators based on the ecological, economic and social characteristics of the Alborz province, while reviewing the internal and external resources, and using 30 expert opinions were sought in order to reach a collective consensus. Also to measure their weight, the FAHP fuzzy hierarchy process was used. Then, using weighted linear combina...

Calculation the phantom scatter factor for the linear accelerators device

Introduction: In the last few decades, a lot of monte carlo codes have been introduced for medical applications. this is important because through simulation, we are fully independent of the spectral scattering factor that we are not able measure in real terms. The effect of the radiation energy, the dimension of the radiation field, the sensitive volume of the ion chamber on t...
