Each year, students in CIE 429 learn about the theory associated with the analysis and design of beams, slabs and columns made of reinforced concrete. This semester, Stavridis and Seyedsina ...

Understanding how helical, curved beams operate — how their spiral cuts accommodate angular and parallel misalignment, axial motion, and system vibrations — is the key to knowing how they will perform ...

There's no escaping it: Though the tractor beam is a staple of sci-fi space-faring scenarios, it's also extremely counter-intuitive. How does one pull something in via an outward-shooting beam? A few ...

The Contact stress and area problems set up like this. Picking calculation produces the outputs shown. Beam-section properties pop up with either of the beam modules, or can be accessed on its own.

First, the payload requirements and problems faced by traditional multi-beam antenna are described. The user beam of the VHTS payload system mainly uses Ka-band multi-beam antenna for a large range of ...

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long ...
