Dose distributions for (left) an uncollimated plan and (centre) a plan with apertures for proton therapy of an optic glioma; the right panel shows the dose differences. The use of apertures reduces ...

Current satellite communication systems use static beams, with little or no options of adjusting beam capacity to a varying demand. Beam hopping, based on the DVB-S2X broadcasting standard, allows ...

The growing problem of space junk around Earth could be cleaned up in part using the same forces that give you a static shock when you touch a doorknob on a windy day. By shooting space debris with an ...

Optical scintillation imaging is proving feasible as a quality assurance (QA) tool for small static beams and for pre-treatment verification of radiosurgery and volumetric-modulated arc therapy (VMAT) ...

Working with WORK Microwave and Eutelsat, the Fraunhofer Institute for Integrated Circuits (IIS) has successfully demonstrated beam hopping in an over-the-air test for the first time. Current ...

Yongcui Mi has developed a new technology that enables real-time shaping and control of laser beams for laser welding and directed energy deposition using laser and wire. The innovation is based on ...

Tractor beams sound like science fiction straight out of “Star Trek,” but one U.K.-based researcher is showing off how you could make your own using a 3D printer. Short for “attractor” beams, the ...

This course presents the fundamental principles of structural analysis, determination of reactions, internal forces and deflections under the static load conditions. The course is mainly focused to ...
