سازمان های قانون گذار صنعت دریانوردی، سالهای زیادی سعی خویش را در جهت بهبود این صنعت، از طریق ارائه استانداردهای فنی، کاربرد تکنولوژی های جدید و تصویب قوانین بین المللی مرتبط با این استانداردها و تکنولوژی ها صرف نمودند. بررسی سوانح دریایی نشان داد که عامل انسانی سهم عمده ای از دلایل وقوع حوادث ناگوار دریایی می باشد. imo از سال 1998 در راستای پیشگیری از خطای انسانی در کشتی های کنوانسیونی، استقرا...

background: to reduce the dose to normal tissues surrounding the treated breast, a uniform magnetic field was used within a humanoid phantom in breast radiotherapy. materials and methods: monte carlo simulations were performed with geant4, irradiating humanoid phantoms in a magnetic field. to reconstruct phantoms, computed tomography (ct) data slices of four patients were used for the monte car...

Experiments on the multiterawatt (MTW) laser at the Laboratory for Laser Energetics will study the effect of the focal-spot shape on the forward acceleration and collimation of electrons. A compact electron spectrometer has been developed to record the energy spectra of electrons ejected in the interaction of the laser at multiple angular locations simultaneously. The modular system with replac...

A new β-NMR/β-NQR setup is developed to study nuclear magnetic dipole moments and electric quadrupole moments at the LISE fragment separator at GANIL. Two key elements make the new design very powerful: the homogeneous magnet and the strong radio-frequency amplifier. The combination of both makes it possible to examine a broad spectrum of magnetic dipole and electric quadrupole moments. Several...
