Architecting Information Acquisition To Satisfy Competing Goals with Kenneth J. Hintz

Information Based Sensor Management  (IBSM) was briefly described in an earlier posting, but the question arises as to what are the criteria which led to this inevitable approach to sensor management.  That is, how do you architect the noncommensurate elements of IBSM while satisfying competing mission goals.  We present here a brief synopsis of an …

Cybersecurity vs. Productivity: How Do We Meet In The Middle?

Recently, I have seen many more discussions about cybersecurity breaches. Could this be down to many more people working from home? Or is expected due to the increase of technology in our day-to-day lives? Or both? This Forbes article from 2018 – https://www.forbes.com/sites/sallypercy/2018/11/27/the-top-three-business-priorities-for-leaders-over-the-next-three-years/?sh=26358f834ec9 – said that companies would be making cybersecurity and big data one …

Smart Fibre from Space – Moving the Internet into the Galaxy? with Geoff Varrall

Once in a while we find ourselves writing about topics which are relatively new to us. My comfort zone as an author is RF engineering but suddenly it seems that free space optical wireless is becoming important in space and terrestrial networks. Counter intuitively this became obvious when looking at the economics of subsea fibre …

A Deeper Dive into High-Thoroughput Satellites with Hector Fenech

The satellite communication landscape is evolving. The traditional services are not sustaining the growth that the space industry is used to, and new services are showing new promises. Broadband access is such an area encompassing two main applications, namely fixed broadband and mobile broadband. In these days where economics are becoming the deciding factor in …

Artech House Releases the Definitive Resource for In-Band Full-Duplex Wireless Systems with Kenneth Kolodziej

This book is the definitive resource for in-band full-duplex (IBFD) wireless systems. IBFD technology allows devices to transmit and receive signals on the same frequency at the same time, but has intentionally been avoided in a wide range of traditional systems. This is due to the significant self-interference that is generated by a transmitter co-located …

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 …

Noise Temperature Theory and Applications for Deep Space Communications Antenna Systems with Tom Otoshi

Tom’s Low Gain Antenna (LGA) on Mars Pathfinder that landed on the surface of Mars on July 4, 1997. This is a real photograph of the LGA and landscape of Mars. Courtesy of NASA/JPL-Caltech. March 21, 2009 Tom is age 78 years old Artech House supports its authors long after their books publish, and our …
