Sometimes as engineers we get depressed by the marketing hype applied to what are perceived as new technology opportunities. Smart Cities are an exemplar of this problem. A local satirical journalist used to point out that the easiest way to uncover absurdity was to proposition the opposite, for example, ‘Dumb Cities, the future?’ But there …
In recent years the proliferation of internet connected devices is enabling the Internet of Things paradigm, which is already disrupting and revolutionizing entire sectors of the global economy including healthcare, transport, trade, energy and industry.

Read on to find out what Rolf Oppliger, who wrote End-to-End Encrypted Messaging, had to say: What are some problems your book can help readers solve? The …
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 …
Reliability engineering and management primarily focuses on preventing and minimizing failures and their consequences, whether those failures gravely threaten safety, reduce mission effectiveness, or simply increase costs. Most engineering disciplines and systems can effectively use this body of knowledge. But statistical analysis of data is perhaps the area of reliability engineering that discourages the most people. …
The Long Read Every so often we find ourselves embarking on a small piece of research that explodes into a major project. This happened to me this month after a chance encounter with a neighbour who is a senior strategist for one of the oil majors. We were talking about the electric car that sits …
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 …
