RESULTS: Researchers have developed a new approach to analyzing networks and have used it to create a map of the physical links between Internet service providers (ISPs). The map shows that the Internet consists of a dense core of a few well-connected nodes, surrounded by a large number of nodes that can connect to one another without going through the core and an intermediate number of nodes that link to the rest of the network through the core only.

Manufacturing in the United States is in trouble. That's bad news not just for the country's economy but for the future of innovation.
This document is part of the “How-To Guide for Most Common Measurements” centralized resource portal. This tutorial provides a detailed guide for measurement and device considerations to take temperature measurements using thermocouples. Get an introduction to thermocouples, which are inexpensive sensing devices widely used with PC-based data acquisition systems. Also review some specific thermocouple examples and learn how thermocouples work and ways to integrate them into a data acquisition measurement system.
