Are flat pedals better if the platform is convex? Concave? Why not both? While the internet argues about which pedal design provides the best grip and feel, OneUp has been testing prototypes of ...

Science gadgets - This is a optical prism made of high quality K9 grade crystal glass. All surfaces of this little prism can be refracted, and it presents different at different angles in the same ...

To deal with the complicated non-convex optimization problem, an alternating optimization (AO)-based algorithm is adopted to decouple it into three subproblems which are further solved individually.

To be specific, we first derive the IRS reflection phase shift by using the semidefinite relaxation (SDR) and concave-convex procedure (CCCP) methods. Then, we obtain the computation and communication ...

The ophthalmic lens industry has grown significantly, due to increasing prevalence of vision disorders due to aging population, employment of digital devices, and lifestyle. Technological advancements ...

The company’s current Z-mount catalog lists forty-seven options, so Nikon fans can expect three or more lens launches over the next year. A key strategy in Nikon’s future plans, however, is expanding ...

There’s a new Scott Gambler prototype downhill bike racing the DH World Cup, and we got a detailed look at it and the hidden tech… Öhlins TTXAir Shocks, and RXF38 and DH38 Forks all get updates to ...

The best protection filters may have no optical effect whatsoever – but it's a heck of a lot cheaper to replace a cracked filter than a cracked lens! When you purchase through links on our site, we ...

Light traveling through a convex lens will converge. If you shined two parallel beams through your gelatin, you saw that parallel beams of light will come together at a point on the far side of a ...
