Innovative ship designs and optimized production techniques are key factors for the success of European shipbuilders in the market for complex one-of-a-kind ships. German and European shipyards benefited significantly from the worldwide increase in orders, resulting in order books well filled for the coming years.

Maintaining and improving this market position requires developing s

Newly published research by a Princeton engineer suggests that understanding how air travels across the sunroof of a car may one day make jet engines less noisy.

Clarence Rowley, an assistant professor of mechanical and aerospace engineering, did not actually conduct his experiments on a sunroof. Rather, he and collaborators used computer simulations and subsonic wind tunnels at Princeton and at the U.S. Air Force Academy in Colorado Springs, to experiment with models that rese

The research team led by Norberto López de La Calle at the Department of Mechanical Engineering at the University of the Basque Country, have designed a new model for optimising the high-speed, 3- or 5- axis milling of complex parts. One of the objectives in this field has been the development of a methodology for the a priori estimation of errors due to flexion of the milling-machine housing system given that some errors, induced by cutting forces, lead to non-compliance with the tolerances of c

A pioneering manufacturing process that can turn titanium, stainless steel and many other metals into a new breed of engineering components could have a big impact across industry.

Unlike conventional solid-metal components, the new parts have a tiny lattice-like structure, similar to scaffolding but with poles twice the diameter of a human hair, making them ultra-light. Because loads are channelled along the poles, the parts can comprise up to 70% air while remaining strong enough

In what promises to be an important advance, researchers at the University of California, Santa Barbara have developed a novel laser by bonding optical gain layers directly to a silicon laser cavity. This hybrid laser offers an alternative to silicon Raman lasers and is an order of magnitude shorter. The laser is optically pumped, operates in continuous wave mode, and only needs 30 mW of input pump power.

This evanescent silicon laser demonstration is the first step toward an electrica

Surface alignment of liquid crystal multilayers evaporated on a photoaligned polyimide film observed by surface profiler

In order to successfully fabricate a commercial Liquid Crystal Display, uniform orientation of the liquid crystal (LC) molecules is required. Traditionally this molecular alignment of liquid crystal is achieved by physically or chemically treating the surface. A simple method used to achieve preferred orientation is rubbing but this may produce dust, static chargi
