When computer-aided design (CAD) software and digital 3D modeling began replacing manual drafting tables and clay modeling ...

Phil Goldstein is a former web editor of the CDW family of tech magazines and a veteran technology journalist. He lives in Washington, D.C., with his wife and their animals: a dog named Brenna, and ...

Computer-aided designs, such as this model of a fingertip-sized heart pump, can reduce the number of physical prototypes that must be made. Computer-aided design (CAD) is a tool intended to facilitate ...

In the early days of the semiconductor industry, integrated circuits were designed by one or two engineers with slide-rules, hand-drawn on paper, and then given to a lithographer to print onto silicon ...

Computer Aided Design (CAD) encompasses the digital authoring, modification and documentation of two- and three-dimensional models for engineering and manufacturing. At its core are two principal ...

The selection of the proper materials for a structural component is critical to engineering design. Existing design procedures may currently be sufficient, especially where experience exists, but ...

RoboGrammar is a new system that automates and optimizes robot design. The system creates arthropod-inspired robots for traversing a variety of terrains. It could spawn more inventive robot forms with ...

There’s nothing new about testing and analyzing product prototypes virtually. Finite element analysis (FEA) and computational fluid dynamics (CFD), collectively CAE, have been around for years.

A novel MIT-developed system makes it possible to design robot shapes and determine its optimal ability to traverse a particular terrain. The simulation-based system is called RoboGrammar and is a ...

Selecting the proper materials for a structural component is critical to engineering design. Materials selection is governed by many factors, some of which are in opposition. The principal selection ...

The aerospace and electronics industries have long applied computational models to not only design airplanes and chips, but also to simulate and optimize their performance. There have, until recently, ...
