the evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. the rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. in the current study, the mentioned phenomen...

The lower structure of a building construction consists foundation and layer soil to support the load upper construction. condition under is closely related behavior itself when it receives loads, for example failures that occur in sub-grade embankment foundation, namely too soft so carrying capacity withstand small, as result settlement occurs large. So must be strong, stable, safe, does not d...

conclusions our study demonstrated that 3d tvs has a good efficacy and reliable agreement with hysteroscopy in diagnosis of uterine lesions among infertile women. therefore, it can decrease the number of diagnostic hysteroscopies. results totally, 153 women were recruited in the investigation. patients aged 30.78 ± 4.79 years in average and the duration of infertility was 4.2 ± 2.91 years among...

objective: the aim of this study was to evaluate the influences of reconstruction and attenuation correction on the differences in the radioactivity distributions in 123i brain spect obtained by the hybrid spect/ct device. methods: we used the 3-dimensional (3d) brain phantom, which imitates the precise structure of gray mater, white matter and bone regions. it was filled with 123i solution (20...

introduction: three-dimensional (3d) scanners are widely used in medicine. one of the applications of 3d scanners is the acquisition of anthropometric dimensions for ergonomics and the creation of an anthropometry data bank. the aim of this study was to evaluate the precision and accuracy of a modified 3d scanner fabricated in this study. methods: in this work, a 3d scan of the human body was o...
