China has built a machine that treats gravity like a dial, not a constant, turning the pull we feel on our bodies into a variable that can be cranked up hundreds or even thousands of times. In doing ...

Running a single mile — at about a 10-minute pace — consists of 1,700 steps. And each one of those steps produces ground reaction forces of about two and a half times your body weight. And you know ...

Abstract: This paper studies the fundamental limits of the minimum average length of variable-length compression when a nonzero error probability ε is tolerated. We ...

South Korea’s Hanwha Engine has produced what it calls the world’s first X-DF engine equipped with variable compression ratio (VCR) technology for LNG carriers, designed to reduce methane slip by up ...

WinGD-designed X-DF engine built for LNG carrier promises to cut methane slip Engine manufacturer and Hanwha Ocean subsidiary Hanwha Engine has built what it calls the world’s first variable ...

The innovative engine appears to be a victim of its own complexity. It couldn't come at a worse time for Nissan. Nissan's variable-compression engine once held so much promise. The so-called VC-Turbo ...

Abstract: While deep learning image compression methods have shown an impressive coding performance, most of them output a single-optimized-compression rate using a trained-specific network. However, ...

SAE International Journal of Engines, Vol. 10, No. 3 (June 2017), pp. 817-831 (15 pages) ABSTRACT Increasing compression ratio (CR) is one of the most fundamental ways to improve engine efficiency, ...

Swiss marine power company WinGD will realise the first commercial instalments of its new variable compression ratio (VCR) technology on two new dual-fuel LNG powered vessels being built for NYK Line.

Two new LNG dual-fueled vessels being built for NYK Line will be the first with two-stroke engines featuring the variable compression ratio (VCR) technology announced by Swiss-headquartered engine ...
