In this paper, a novel analytical method was developed based on statistical energy analysis framework to evaluate sound transmission loss through ventilated windows. The proposed method was compared to numerical and analytical models available in the literature. Results showed the success and advantage of the proposed model in predicting the acoustic performance of the ventilated window and the...

The known ore deposits and mineralization trends are important key exploration criteria in mineral exploration within a specific region. Fry analysis has conventionally been considered as a suitable method to determine the mineralization trends related to linear structures. Based upon literature sources, to date, no investigation has been carried out that includes the Sensitivity Analysis of Fe...

Abstract Creating suitable classrooms that can meet the educational needs of mentally-retarded students is vitally important. The present study explores the effect of three physical characteristics of classroom environment on the creativity of educable mentally-retarded children: window view, window size, and classroom size. The participants, one hundred 9-to-11-year-old girl students, took th...

Introduction: Scatter radiation is one of the major sources of error in nuclear medicine data processing. Different methods of scatter correction have been introduced in order to improve the quality of data. However the best method is to avoid recording of scatter photons in acquisition. The only difference between scattered and non-scattered photons is the energy. Pulse height analyzer i...

introduction: the different factors that affect the camera uniformity of single photon emission computed tomography (spect) technique have been analyzed including peak shift (%) and window width of energy. the effect of peak shift and window width on spect image uniformity has been investigated using a point source to perform intrinsic flood images. methods:the relation between calculated integ...
