Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control
Advanced Functional Materials, EarlyView.A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

This book on reference systems is the first comprehensive review of the problem of celestial and terrestrial reference systems and frames. Over 20 years, the importance of this problem emerged slowly as the accuracy of new observational techniques improved. The topic has already been approached in several symposia such as Stresa (1967), Morioka (1971),

A change of variables is often used to reduce the complexity of the differential equations (voltage equations) that describe the behavior of electric machines. All known real transformations are obtained from the general transformation by simply assigning the speed of the rotation of the reference frame. This chapter sets forth this transformation and,

The Kyoto Protocol from 1997 heralded a new era toward a sustainable future many believed; however, it should come as no surprise that little has happened. While some might argue that it is because some has not ratified the agreement, the reality is that it could never succeed.

The frame-indifference principle, one of the fundamental concepts of continuum mechanics, means that a physical process remains unchanged when it is observed by different observers.

The objective of this chapter is to provide a frame of reference for the study’s research questions. I will therefore introduce the innovation concept (section 2.1) by distinguishing between innovation as an outcome (section 2.1.1) and innovation as a process (section 2.1.2).

The culture and the politics of early modern England have both inspired prodigious quantities of scholarship. These subjects have normally been studied separately, however, by experts trained in different disciplines, employing different tools, asking different questions and often taking little notice of each other’s preoccupations.

This chapter begins with an introduction to the formalism used to project four-dimensional spacetime into a 3-dimensional spatial 3-space. Then we apply this formalism to deduce the spatial geometry in a rotating reference frame and discuss Ehrenfest’s paradox.
