Predicting Fusing Time of Overloaded PCB Traces Can We Predict It At All? with Douglas Brooks, PhD and Dr. Johannes Adam

When Traces Melt:  Figures 1 and 2 (Note 1) illustrate traces on two different boards. Each figure illustrates the trace at the moment it fuses (melts) due to a significant current overload. The fusing mechanisms are clearly different. So what was different? Here is the first hint. Assume there is a current that is just …

Next-Generation Emergency Services, the current state of emergency services; how to plan and execute a move to a standards-compliant NG9-1-1 service with Barbara Kemp and Bart Lovett

Waves, either electromagnetic (EM) or acoustic (AC) interact with objects and scatter. The addition of incident and scattered fields form the total fields. Scattered fields include (but not limited with) reflections, refractions, and diffractions. The Handbook of Next Generation Emergency Services by Barbara Kemp and  Bart Lovett is about diffraction modeling and simulation. Scattering has gained …

Applications of Geographic Information Systems for Wireless Network Planning with Francisco Saez De Adana, Josefa Gómez Pérez, Abdelhamid Tayebi Tayebi and Juan Casado Ballesteros

A Geographic Information System (GIS) is a computer system that gathers, analyses, stores, checks, manipulates, manages, and visualizes data related to spatial locations on Earth’s surface. A GIS works as a database with geographic information (alphanumeric data) that is associated by an identifier common to the graphic objects of digital maps. In this way, when …

Everything You Know About Via Temperatures is Wrong! with Doug Brooks

Everything You Know About Via Temperatures is Wrong! Via temperatures are not related to via current Via temperatures are not related to current density Douglas Brooks, PhD and Dr. Johannes Adam Via Temperatures and Current: The common understanding in the electronics industry is that via temperatures, just like trace temperatures, are a function of the …

Problem Solving 101 with Y.J. Liu – On understanding the OFDM algorithms

At Artech House, we ask our authors what problems their books can help readers solve. In this series, we share what our authors aim to do in their writing. Read on to find out what Y.J. Liu, who wrote Introduction to OFDM Receiver Design and Simulation had to say: Best source for fundamental understanding of …
