Scientists in Finland have created a special platform to assess the performance of PV modules operating under Arctic conditions. Specifically, it provides data for efficient system design and ...

3D printers can produce a wide range of three-dimensional objects using various materials. Depending on the technology, this may involve curing a liquid resin with a light source (SLA, DLP, LCD) or ...

Abstract: The lack of range information for passive measurements complicates sensor registration, requires one to address the arctangent function's singularities, and prevents one from applying ...

Abstract: This paper describes the architecture and IC implementation of a rectangular-to-polar coordinate converter for digital communication applications. The architecture core uses small lookup ...

Chalk is fun to draw with, and some people even get really good at using it to make art on the sidewalk. If you don’t like tediously developing such skills, though, you could go another route.

Use AutoCAD's "Extrude" and "Revolve" commands to turn 2-D designs into 3-D models. "Extrude" is how 3-D modelers to refer to the technique of stretching a 2-D shape into 3-D space. AutoCAD performs ...

In all the commentary about Donald Trump’s choice of Senator J. D. Vance as his running mate—he’s the survivor of a tumultuous upbringing in small-town Ohio, a former marine, a Yale Law graduate, the ...

Faced with global platforms, we need global responses. Thanks to the creation of this global network of regulators, hosted by UNESCO and already supported by participants from 124 countries, we will ...

Polar coordinates are an alternative coordinate system to the commonly used Cartesian (rectangular) coordinates. They are particularly useful in situations where data can be more easily represented ...

It’s a boom time for higher education organizing. Last year alone, 26 new bargaining units representing over 40,000 graduate student workers, postdoctoral workers or researchers earned certification ...
